Why GAO Did This Study: 

During the late 1990s, many petroleum companies merged to stay 
profitable while crude oil prices were low, and in recent years mergers 
have continued. Congress and others have concerns about the impact 
mergers might be having on competition in U.S. petroleum markets. The 
Federal Trade Commission (FTC) has the authority to maintain 
competition in the petroleum industry and reviews proposed mergers to 
determine whether they are likely to diminish competition or increase 
prices, among other things. GAO was asked to examine (1) mergers in the 
U.S. petroleum industry and changes in market concentration since 2000 
and (2) the steps FTC uses to maintain competition in the U.S. 
petroleum industry, and the roles other federal and state agencies play 
in monitoring petroleum industry markets. In conducting this study, GAO 
worked with petroleum industry experts to delineate regional markets 
and to develop estimates of refinery gasoline production capacity in 
order to calculate market concentration. GAO used public and private 
data as well as interviews for its analyses. 

What GAO Found: 

More than 1,000 U.S. mergers occurred in the petroleum industry between 
2000 and 2007, mostly between firms involved in crude oil exploration 
and production. According to experts and industry officials, mergers in 
this segment were generally driven by the challenges associated with 
producing oil in extreme physical environments, such as deepwater, as 
well as increasing concerns about competition with national oil 
companies and access to oil reserves in regions of relative political 
instability. Industry officials from the segments of the petroleum 
industry that transport, refine, and sell petroleum products reported 
that mergers were generally driven by the desire for greater efficiency 
and cost savings. Despite these gains, mergers have the potential to 
enhance a firm’s ability to exercise “market power,” which potentially 
allows it to raise prices without being undercut by other firms. GAO 
measured market concentration with an index that FTC uses, where market 
regions with few, large firms are considered to be highly concentrated 
and have a greater potential for market power. Conversely, market 
regions with many smaller firms are considered to have low or moderate 
concentration and generally have less potential for firms to exercise 
market power. GAO found that market concentration changed little but 
varied by industry segment and market region. GAO found that market 
concentration among firms involved in crude oil exploration and 
production was low and stable between 2000 and 2006, while 
concentration among refiners was generally moderate across those years. 
Regarding wholesale gasoline suppliers on a state-by-state basis, 35 
states were moderately concentrated in their number of wholesale 
gasoline suppliers in 2007, and this number was fairly stable from 
2000. GAO found that the following 8 states had highly concentrated 
wholesale gasoline supplier markets in 2007: Alaska, Hawaii, Indiana, 
Kentucky, Michigan, North Dakota, Ohio, and Pennsylvania. 

While FTC reviews evidence and considers a number of competitive 
factors to predict a merger’s potential effects on competition in its 
analyses of proposed mergers, it does not regularly look back at past 
merger decisions to assess the actual effects of the merger on 
competition or prices after the merger has been completed. Although 
these reviews can be resource intensive, experts, industry 
participants, and FTC agree that regular retrospective reviews would 
allow the agency to better inform future merger reviews and to better 
measure its success in maintaining competition. In addition to FTC’s 
efforts in reviewing proposed mergers, other federal agencies, 
including FTC, and some states also monitor aspects of petroleum 
industry markets. For example, the Federal Energy Regulatory Commission 
monitors petroleum product pipeline markets and regulates pipeline 
rates accordingly. 

What GAO Recommends: 

To enhance FTC’s effectiveness in maintaining competition in the U.S. 
petroleum industry, GAO is recommending that FTC (1) conduct more 
regular analyses of past petroleum industry mergers and (2) develop 
risk-based guidelines to determine when to conduct them. FTC reviewed a 
draft of this report and said that the recommendations were consistent 
with its self-evaluation initiative, and that it would consider them as 
part of that process.

During the late 1990s, a wave of mergers swept through the petroleum 
industry as a number of companies combined their operations to stay 
profitable while crude oil prices were low. During this time, large oil 
companies such as Exxon and Mobil merged, as did British Petroleum and 
Amoco, leaving fewer major petroleum industry players. In recent years, 
petroleum companies have continued to merge, despite strong profits. 
Because the petroleum industry plays a critical role in providing the 
transportation fuel that moves people and products throughout the 
United States, and with oil prices reaching record levels, Congress and 
others have questioned whether more recent mergers have allowed 
petroleum companies to control too large a share of the markets in 
which they participate, thus reducing their incentive to provide 
competitively priced fuel. 

The Federal Trade Commission (FTC) and the Department of Justice (DOJ) 
have the authority to enforce federal antitrust laws to generally 
maintain competition in all industries, including the petroleum 
industry. To that end, FTC and DOJ generally review proposed mergers 
that are likely to impact U.S. markets to determine whether they are 
likely to diminish competition or increase prices. FTC has lead 
responsibility for federal reviews of petroleum industry mergers, and 
has said publicly that it scrutinizes mergers in the energy industry 
more closely than those in any other industry.[Footnote 1] In reviewing 
a proposed merger, FTC generally looks at the participants' market 
shares--the percentage of the same products that companies supply to a 
particular geographic market--and other factors that affect 
competition. FTC uses the market shares to develop an index of market 
concentration, where firms with large market shares are weighted more 
heavily. Market areas with a number of small firms would be 
unconcentrated or moderately concentrated, while areas with fewer large 
firms would be highly concentrated. Other things being equal, mergers 
that cause a market area to become highly concentrated potentially 
allow one firm, or a small group of firms, to exercise "market power" 
and control the market to increase consumer prices above competitive 
levels. On the other hand, mergers that lead to a more highly 
concentrated market might also improve efficiency and reduce costs, and 
firms may pass these savings on to consumers in the form of lower 
prices. Federal antitrust authorities try to predict the impact of a 
merger on competition, including the impact on prices, before allowing 
the merger to take place. After a merger is completed, an agency may 
review past merger decisions to monitor how well the agency achieved 
its goals.[Footnote 2] In fact, federal government standards for 
internal control require federal agencies, including FTC and others, to 
establish goals and measure performance to improve management and 
program effectiveness. [Footnote 3] 

Antitrust enforcement agencies generally examine concentration in the 
petroleum industry by first defining the segment of the industry 
involved and then defining the geographic region where this portion of 
the industry operates. More specifically, the industry is divided into 
three segments: the crude oil exploration and production segment 
(upstream), the refining and marketing segment (downstream), and a 
segment that consists of the infrastructure used to transport crude oil 
and petroleum products to customers (midstream). Some companies operate 
in all three segments of the petroleum industry and are deemed "fully 
vertically integrated," while others operate in only one or two of the 
industry segments and may be referred to as "independent," among other 
things. Chevron is an example of a fully integrated petroleum company, 
with operations in all three segments, while Wawa--the convenience 
store chain--is an example of a firm operating in only one market 
segment as a downstream independent fuel retailer. A proposed merger 
between companies in the same industry segment and geographic market 
region would likely spur FTC to look at each company's market shares 
and other competitive factors in that geographic market region. 

In this context, we were asked to examine (1) mergers in the U.S. 
petroleum industry, and changes in market concentration since 2000, and 
(2) the steps that FTC uses to maintain competition in the U.S. 
petroleum industry, and the roles other federal and state agencies play 
in monitoring petroleum industry markets. GAO will examine the 
potential effect of mergers and market concentration on wholesale 
gasoline prices in a forthcoming report. 

To examine U.S. mergers since 2000, we purchased and analyzed petroleum 
industry merger data from John S. Herold, Inc.[Footnote 4] (J.S. 
Herold), and interviewed a number of industry experts and market 
participants. U.S. mergers included mergers that had a reported 
location in the United States or were diversified across multiple 
countries, but we had reasonable evidence to believe included a United 
States location. We decided this definition coincided with mergers that 
would affect U.S. markets and, hence, that FTC could potentially 
review. We also limited our analysis to mergers (1) that occurred 
between January 2000 and May 2007, (2) that had a transaction value of 
$10 million or more, and (3) whose key asset was not related to natural 
gas or other natural gas products. In examining changes in market 
concentration, we focused on the upstream crude oil production segment 
and two downstream subsegments: gasoline refiners and wholesale 
gasoline suppliers. We did not examine changes in concentration in the 
midstream segment because of a lack of available data. We purchased 
data on upstream crude oil production from the Oil and Gas Journal, and 
used data from the Department of Energy's Energy Information 
Administration (EIA) on downstream gasoline refining and wholesale 
gasoline suppliers. We worked with petroleum industry experts to define 
geographic market regions in order to calculate market concentration in 
these segments of the industry. We calculated changes in concentration 
in a single global market for upstream crude oil producers, seven U.S. 
"spot market" regions for gasoline refiners, and U.S. states for 
wholesale gasoline suppliers. The markets we defined were intended to 
provide an overview of petroleum industry concentration and would not, 
in many cases, correspond to geographic markets that FTC might use to 
inform its judgments about anticompetitive market conditions for the 
purposes of enforcement. We assessed the reliability of the data we 
collected and found it sufficiently reliable for the purposes of this 
report. To examine FTC's steps for maintaining competition and other 
federal and state agencies' roles, we interviewed FTC staff; reviewed 
official agency documents; and interviewed experts in the fields of 
antitrust and industrial organization, as well as petroleum industry 
officials. In addition, we reviewed documents and interviewed officials 
from other federal and state agencies that have roles in monitoring 
petroleum industry markets, such as the Federal Energy Regulatory 
Commission (FERC) and the Commodity Futures Trading Commission (CFTC), 
who are involved in monitoring pipeline and futures markets, 
respectively. See appendix I for more detailed information on our 
objectives, scope, and methodology. We conducted this performance audit 
from March 2007 to September 2008 in accordance with generally accepted 
government auditing standards. Those standards require that we plan and 
perform the audit to obtain sufficient, appropriate evidence to provide 
a reasonable basis for our findings and conclusions based on our audit 
objectives. We believe that the evidence obtained provides a reasonable 
basis for our findings and conclusions based on our audit objectives. 

Results in Brief: 

More than 1,000 U.S. mergers occurred in the petroleum industry between 
2000 and 2007, and we found that market concentration changed little 
but varied by industry segment and market region. Most of the mergers, 
as well as the mergers of greatest value, occurred in the upstream 
segment, including 6 mergers valued at more than $10 billion each. 
According to many of the experts and industry officials with whom we 
spoke, key drivers of upstream mergers included challenges associated 
with exploring and producing oil in extreme physical environments, such 
as deepwater, as well as concerns about competition with national oil 
companies and access to oil reserves in regions of political 
instability. Petroleum industry experts with whom we spoke noted that 
mergers can better position oil companies to successfully explore in 
extreme environments and compete in the global oil market, as well as 
diversify their exploration interests across multiple countries or 
regions. U.S. mergers in the midstream and downstream segments were 
less numerous and had lower overall transaction values than the 
upstream segment. Mergers in these segments were reportedly driven by 
the desire to improve efficiencies and reduce costs, particularly in 
the pipeline, refining, and marketing subsegments. Despite the gains 
that can result from mergers in the petroleum industry, officials and 
experts reported that mergers have the potential to allow companies to 
exercise market power and raise consumer prices. Regarding industry 
market concentration, concentration levels in the crude oil producing 
segment of the industry remained relatively low and stable between 2000 
and 2006, while concentration among refiners in several regions 
throughout the United States also changed little but was generally 
moderate. Regarding wholesale gasoline suppliers on a state-by-state 
basis, 35 states were moderately concentrated in their number of 
wholesale gasoline suppliers in 2007, and this number was fairly stable 
from 2000. The following 8 states had a highly concentrated number of 
wholesale gasoline suppliers in 2007: Alaska, Hawaii, Indiana, 
Kentucky, Michigan, North Dakota, Ohio, and Pennsylvania. 

FTC primarily reviews proposed mergers to maintain petroleum industry 
competition, while other federal and state agencies, including FTC, 
have roles in monitoring petroleum industry markets. While FTC reviews 
evidence and considers a number of competitive factors to predict a 
merger's potential effects on competition in its analysis of proposed 
mergers, it does not regularly look back at past merger decisions to 
assess the actual effects of the merger on prices--there have been only 
three such reviews, despite the many mergers that occurred in the 
petroleum industry between 2000 and 2007. Although these reviews can be 
resource intensive, experts, industry participants, and FTC agree that 
regular retrospective reviews would allow the agency to better inform 
future merger reviews and better measure its success in maintaining 
competition. However, FTC does not plan to develop guidelines for more 
frequently conducting these retrospective reviews and told us it has 
limited resources to devote to such reviews. FTC also performs 
supplemental activities to monitor petroleum industry markets in 
general--not necessarily related to mergers. For example, FTC staff 
told us the agency monitors wholesale gasoline prices in some locations 
to identify and investigate unusual price spikes. Other federal 
agencies also monitor petroleum industry markets; for example, FERC 
monitors petroleum product pipeline markets and regulates pipeline 
rates accordingly. Some states also monitor petroleum industry markets, 
although they generally do so in response to complaints from consumers, 
and the level of monitoring varies from state to state. Some states 
actively monitor market competition and fuel prices on a continual 
basis, while other states do not monitor the petroleum industry at all. 

To enhance FTC's effectiveness in maintaining competition in the U.S. 
petroleum industry and make efficient use of FTC's resources, we are 
recommending in this report that FTC (1) conduct more regular 
retrospective analyses of past petroleum industry mergers and (2) 
develop risk-based guidelines to determine when to conduct these 
analyses given its limited resources. In general, the FTC Chairman 
commented that the recommendations in this report were consistent with 
the goals outlined in a current self-evaluation initiative, and that 
the agency would consider our recommendations to conduct more regular 
retrospective analyses of petroleum industry mergers using a risk-based 
approach along with other recommendations resulting from this 
initiative. 

Background: 

In 2007, the United States produced an average of 8.5 million barrels 
of petroleum per day, or about 10 percent of the global average 
production of 84.4 million barrels per day. As a percentage of total 
world consumption, the United States was the largest consumer of crude 
oil and petroleum products in 2007, with an average consumption of 20.7 
million barrels per day. According to EIA statistics, imports provide 
the United States with about 60 percent of its overall petroleum needs. 
Of the petroleum refined in the United States, approximately 46 percent 
is used for gasoline, primarily for use in the transportation sector. 
Second to gasoline, distillate fuel oil (including diesel)--which is 
used for a variety of heating, energy, and transportation purposes-- 
accounts for 21 percent of petroleum refined in the United States, 
followed by kerosene-type jet fuel at 9 percent. The remaining 24 
percent of crude is used to make other products, such as heavy fuel oil 
or asphalt. 

Firms operating in the petroleum industry range widely, from large 
corporations that operate in multiple countries and across various 
segments of the industry, to small firms that operate exclusively in 
the United States or in only one segment of the industry. Companies 
operating in the upstream segment--which includes the exploration and 
production of crude oil--include fully vertically integrated companies 
as well as independent producers. Fully vertically integrated companies 
are generally large, multibillion-dollar publicly traded companies, 
such as Exxon Mobil. By contrast, independent producers range from 
extremely small, privately owned operations to multibillion-dollar 
publicly traded companies, such as Occidental. 

Companies operating in the midstream segment--which includes the 
transport of crude oil and refined petroleum products--include firms 
that manage pipelines, marine tankers and barges, railways, and trucks. 
Midstream companies also range widely in size and can include large, 
vertically integrated companies as well as smaller independent 
operators of pipelines or other modes of transportation. Pipelines are 
the most common, and considered the most efficient, mode of 
transporting crude oil and petroleum products in the United States from 
production points to refineries and from refineries to storage 
terminals. Nationwide, there are about 200,000 miles of pipeline across 
all 50 States, through which approximately 66 percent of petroleum 
products are transported.[Footnote 5] 

Companies operating in the downstream segment include firms that refine 
crude oil as well as firms that market refined petroleum products. 
Refining involves the transformation of crude oil into the various 
petroleum products, such as gasoline, distillate fuel oil, and jet 
fuel, as well as heavier products, such as asphalt. According to data 
from EIA, as of January 1, 2008, there were 150 operable refineries in 
the United States. In 2002, about 60 firms, including large, fully 
vertically integrated companies and independent firms, owned these 
refineries. For example, as of January 2007, ConocoPhillips owned 12 
U.S. refineries and 19 refineries worldwide. Petroleum marketing 
involves purchasing refined petroleum products from refiners and 
selling them to wholesaler and retail firms. There are different 
classes of wholesale gasoline purchasers in the United States, and the 
prices they pay depend, in part, on the type of relationship they have 
with the refiners. 

Given the nation's dependence on gasoline and other petroleum products, 
competition among petroleum industry firms has long been considered of 
paramount importance to the economy. In 1890, Congress passed the 
Sherman Act[Footnote 6] to counter anticompetitive practices in several 
industries, including some of Standard Oil's practices in the petroleum 
industry. In 1914, Congress expanded its antitrust authority by 
creating FTC and enacting the Clayton Act.[Footnote 7] As such, merger 
activity in all three segments of the industry and the potential for 
anticompetitive behavior through industry consolidation has long been 
the subject of interest on the part of many industry observers and 
government regulators. 

FTC is the federal antitrust agency that is responsible for reviewing 
proposed mergers in the petroleum industry, with the goal of 
maintaining industry competition. FTC reviews mergers of firms in the 
petroleum industry if their operations are likely to impact U.S. 
markets, and the agency enforces various antitrust laws. Although FTC 
says that it scrutinizes mergers in the petroleum industry more than 
any other industry, FTC's statutory authority to review proposed 
mergers in the petroleum industry is the same as in other industries. 
FTC has enforcement and administrative responsibilities from over 60 
laws, but uses 3 statutes to guide its review of all proposed mergers-
-the Clayton Act, the Federal Trade Commission Act, and the Hart-Scott- 
Rodino Act--as outlined in table 1. 

Table 1: Federal Antitrust Statutes--Merger Enforcement: 

Statute: Clayton Act[A]; 
Description: Enacted in 1914, Section 7 of the Clayton Act, 15 U.S.C. § 
18, prohibits an acquisition of stock or assets by any person engaged 
in commerce or in any activity affecting commerce, in any section of 
the country, when the effect of such acquisition may be substantially 
to lessen competition, or tend to create a monopoly. 

Statute: Hart-Scott-Rodino Act[B]; 
Description: Enacted in 1976, Section 201 of Hart-Scott-Rodino added 
Section 7A to the Clayton Act, 15 U.S.C. § 18a, which established 
premerger notification and waiting requirements for persons making an 
acquisition of stock or assets. Both the parties to the acquisition and 
the amount of the acquisition must meet statutory threshold amounts to 
be subject to the premerger notification and waiting requirements. The 
2001 amendments to Hart-Scott-Rodino, among other things, raised the 
threshold size of person and size of transaction amounts and specified 
that they would be adjusted annually on the basis of the prior year's 
Gross National Product. 

Statute: Federal Trade Commission Act[C]; 
Description: Section 5 of the FTC Act, 15 U.S.C. § 45, prohibits unfair 
methods of competition in or affecting commerce and unfair or deceptive 
acts or practices in or affecting commerce. Generally, if an action 
violates Section 7 of the Clayton Act, it is also likely to violate 
Section 5 of the FTC Act.

[End of table] 

While the three statues help direct FTC's review of proposed mergers in 
all industries, Hart-Scott-Rodino provides the framework for the 
premerger review. Hart-Scott-Rodino requires all persons contemplating 
a merger valued at $50 million or more and meeting certain other 
conditions to formally notify FTC and DOJ. The act imposes a 15-day 
waiting period for cash tender offers and a 30-day waiting period for 
most other transactions to allow FTC and DOJ to review the proposed 
merger in an effort to predict its potential effect on competition. 
[Footnote 8] If the initial review does not indicate a need for further 
investigation, the merger can be completed. To ease compliance with 
Hart-Scott-Rodino, FTC and DOJ established a premerger notification 
program in 1978 that set a systematic process for FTC to follow in 
reviewing all proposed mergers and allows the agencies to avoid the 
difficulties and expense of challenging mergers that harm competition 
after they are completed. This gives them the ability to challenge 
proposed mergers before they are completed when remedial action would 
be most effective, if warranted. See figure 1 below for a summary of 
FTC's merger review procedures. 

Figure 1: FTC's Premerger Review Program: 

[See PDF for image] 

This figure provides a description of FTC's Premerger Review Program, 
as follows: 

Reporting: 
A party is required to report a merger to FTC if: 
* the parties to the transaction meet the statutory size thresholds (as 
adjusted) and; 
* the transaction meets the statutory size threshold (as adjusted). 

Waiting Period: 
Filing parties must provide certain financial and legal documents 
pertaining to the merger and must observe a 15-day waiting period 
related to cash tender offers and a 30-day waiting period for all other 
transaction types. 

Initial Review (15-30 days): 
The agency substantively reviews the filing using the information 
provided by the parties as well as publicly available data. Merger can 
be completed if the agency determines that the merger will not harm 
competition. 

Second Request: 
The agency requests additional detailed information if the initial 
filing did not capture the merger’s full impact on competition. 

Response To Second Request: 
Once the parties respond to the second request, the agency has 10 or 30 
days to seek an injunction, unless an extension is negotiated. In some 
cases, this stage lasts between 9 and 12 months and then the agency 
takes action. 

Agency Actions: 
* Allow the merger to be completed. 
* Challenge the merger legally. 
* Require remedial actions, such as divestures, and then allow the 
merger.

FTC staff and DOJ officials told us that they divided their merger 
review portfolio, and that FTC handles all of the petroleum industry 
merger review cases because it has more expertise in that area. 
[Footnote 9] FTC's merger review process is conducted by staff in 
various bureaus and offices throughout the agency, but mainly by the 
Bureau of Economics and the Bureau of Competition. The agency also has 
a Merger Screening Committee composed of at least the Director of the 
Bureau of Competition, section heads of that bureau's divisions, 
representatives from the Bureau of Economics, and other relevant FTC 
staff. The purpose of the group is to determine whether to recommend 
that the Chairman approve and issue a request for additional 
information and to decide other policy matters. 

FTC often calculates market concentration as the first step in 
providing insight into potentially anticompetitive market conditions 
during merger reviews, although each review also involves examining a 
unique set of circumstances and competitive factors that correspond to 
the specific merger. In general, high levels of market concentration-- 
a small number of firms controlling a large percentage of the product 
and geographic market share--have the potential to allow these firms to 
raise prices because the remaining firms are too few to "discipline" 
the market by offering lower-priced products. When firms are able to 
raise prices, either unilaterally or by collusion without other 
producers undercutting them, they are said to have market power. FTC 
and DOJ jointly developed merger guidelines that use the Herfindahl- 
Hirschman Index (HHI) as a key initial measure to evaluate market 
concentration. HHI is based on the market shares and number of firms 
that sell similar products in a given geographic market.[Footnote 10] 
Calculating HHI not only requires estimating market share by firm, it 
also involves identifying the appropriate geographic markets in which 
the firms operate. Firms selling a given product may compete at the 
global level--in which case, the relevant geographic market includes 
sellers worldwide--or in regional, statewide, or smaller markets. For 
example, FTC staff told us that they generally consider crude producers 
to compete globally, refiners to compete regionally, and wholesale 
gasoline suppliers to compete at a more local level. FTC and DOJ merger 
guidelines define three broad categories of market concentration as 
measured by HHI: an unconcentrated market has an HHI of less than 
1,000; a moderately concentrated market has an HHI between 1,000 and 
1,800; and a highly concentrated market has an HHI over 1,800.

More than 1,000 U.S. Mergers Occurred in the Petroleum Industry between 
2000 and 2007, and Market Concentration Changed Little but Varied by 
Market Region and Industry Segment: 

More than 1,000 U.S. mergers occurred in the petroleum industry between 
2000 and 2007. The largest number and greatest value mergers occurred 
in the upstream segment, primarily due to increasingly challenging 
conditions for oil exploration, while midstream and downstream mergers 
were primarily driven by the desire to improve efficiencies and reduce 
costs. We also found in our analysis of the upstream crude oil 
production segment of the industry and the downstream refining and 
wholesale gasoline supply segments of the industry that, in most 
regions, petroleum industry market segments were moderately 
concentrated. Lacking data on midstream, we were not able to determine 
concentration in this segment of the industry. 

Mergers in the Petroleum Industry between 2000 and 2007 Primarily 
Occurred in the Upstream Segment in Response to Increasingly 
Challenging Conditions for Oil Exploration: 

Between January 2000 and May 2007, 1,088 U.S. mergers occurred in the 
petroleum industry.[Footnote 12] The number of mergers that occurred 
each year during this period[Footnote 13] generally increased over the 
period, from 124 mergers in 2000 to 167 in 2006,[Footnote 14] as shown 
figure 2.

About 75 percent of these mergers were asset mergers, or mergers where 
one firm purchases only a portion of another firm's assets, such as 
Tesoro's purchase of 140 retail gasoline stations in California from 
USA Petroleum in early 2007. The remaining 25 percent were corporate 
mergers, or mergers where one firm generally acquires all of another 
firm's stock and assets such that the two firms become one firm. For 
example, in 2002, Phillips Petroleum acquired all of Conoco's stock, 
creating the new firm ConocoPhillips. 

Reported transaction values for U.S. petroleum mergers during this 
period ranged widely, from $10 million to over $10 billion. As shown in 
figure 3, the greatest number of mergers during this period were valued 
between $10 million and $49 million, and between $100 million and $499 
million, accounting for 39 percent and 29 percent of merger activity, 
respectively. Overall, 61 percent of mergers were valued at more than 
$50 million, which is the threshold above which merging firms are 
required to notify FTC so that it can review them for potential 
anticompetitive effects.[Footnote 15] The average value for mergers 
during this period was $497 million, while the median value for mergers 
during this period was $72 million.

The upstream segment of the industry--comprised of oil exploration and 
production endeavors--accounted for approximately 69 percent of the 
1,088 mergers. The midstream segment of the industry--mainly comprised 
of firms that operate pipelines and other infrastructure used to 
transport oil and gas--accounted for about 13 percent. The downstream 
segment of the industry--comprised of firms that refine crude oil and 
market petroleum products--accounted for 18 percent. Figure 4 
highlights this distribution across the segments.

Upstream Segment: 

In the U.S. upstream petroleum segment, some trends were similar to 
those that we previously discussed for the industry overall, with the 
number of mergers over the period generally rising and asset mergers 
comprising approximately 75 percent of all mergers. Upstream mergers 
had the highest transaction values of the three segments, accounting 
for the six most valuable mergers highlighted in table 2 that exceeded 
$10 billion in value. Overall, the average value for upstream mergers 
was $539 million, while the median value was $67 million. 

A key reported driver of U.S. mergers in the upstream segment was the 
increasing challenge associated with exploring and producing oil in 
extreme physical environments. Industry officials at oil companies 
reported that reserves that can be easily and economically produced are 
declining, and that remaining exploration opportunities are 
increasingly located in physically extreme environments, making the 
development of new petroleum resources more costly and technologically 
challenging. Extreme physical environments, such as offshore oil 
reserves in deep water, require costly capital investments in 
specialized drills, pipes, and platforms equipped to operate in deep 
marine environments; operating costs in these environments can be 3.0 
to 4.5 times higher than costs for typical shallow water rigs. In 
addition, extreme physical environments can include "nonconventional" 
oil reserves, such as oil sands,[Footnote 16] that require the use of 
additional and expensive technologies--including additional mining and 
heating--to produce crude oil. Academics and industry officials 
reported that mergers better position oil companies to acquire capital 
and achieve the organizational efficiencies that help enable successful 
exploration and production in these environments. 

Another reported driver of U.S. mergers in the upstream segment was the 
increasing challenge associated with reliably accessing oil reserves 
worldwide. As national oil companies increasingly expand their 
exploration efforts and contend for access to reserves in third-party 
countries, researchers and industry representatives reported that 
national firms, operating on behalf of their home country, often have 
access to more capital, have fewer financial constraints, and have more 
bargaining power via political influence. In light of these reported 
negotiating advantages, companies reported that being large provides 
them with more capital and influence with which to directly compete 
with the national oil companies. Representatives from oil companies 
also reported concerns about political uncertainties in regions where 
key oil reserves are located, because more than 60 percent of world oil 
reserves are in countries where relatively unstable political 
conditions could constrain oil exploration and production.[Footnote 17] 
For example, in 2007, ConocoPhillips abandoned a multibillion-dollar 
investment in Venezuela, after a breakdown in negotiations with the 
government and the national oil company, PDV, resulting in a $4.5 
billion loss for the firm. In light of these concerns, academic and 
industry representatives reported that large firms are better 
positioned to diversify their exploration interests across multiple 
countries or regions, thereby lessening the risk their interests face 
in any one country. 

Despite these rationales, it is uncertain whether mergers have yielded 
the desired results in the upstream segment. One group of academic 
researchers reported that large, international companies have not 
generally expanded their exploration efforts, since exploration 
spending by these companies has not increased above premerger levels 
and some have been unable to replace their reserve assets in recent 
years. These researchers noted in a report on oil companies[Footnote 
18] that this may be a result of the decline in the number of 
accessible large oil fields that afford big companies a comparative 
advantage, due to the increased presence of national oil companies and 
the increasing restrictions on some oil assets worldwide. The report 
noted that smaller production companies have been able to replace their 
existing reserves in recent years, suggesting that large companies are 
not necessarily better positioned for increased exploration in the 
current market. Furthermore, according to industry publications, 
private capital is increasingly available, thereby challenging the 
notion that firms must be large to have access to capital for expensive 
exploration projects. As a result of these concerns, industry and 
academic experts noted that smaller participants in the upstream 
segment remain an effective and competitive force in developing new 
projects, raising questions about the viability of large oil mergers in 
the future. 

Given that the upstream market is a global market, we also briefly 
examined global upstream mergers from January 2000 through May 2007. 
Worldwide, there were 1,722 mergers in the upstream segment during this 
period, the geographic distribution of which is highlighted in figure 
5. As shown in the figure, U.S. mergers comprised about 41 percent of 
total global merger activity in the upstream segment.

Second to the United States, Canada had the highest number of upstream 
mergers, at 31 percent of total upstream merger activity. Taken 
together, this evidence highlights that upstream merger activity during 
this period was heavily concentrated in North America. According to 
industry reports and academic researchers, recent high levels of merger 
activity in Canada have been driven by strong growth in the production 
of crude oil from oil sands, previously considered too technically 
complicated and expensive, but of growing interest to oil companies 
given the high price of oil. This activity was also driven out of 
concern for reliable access to oil, since Canada is considered more 
politically stable than many other regions of the world with oil 
reserves. 

Midstream Segment: 

In the U.S. midstream petroleum segment, the number of asset mergers 
was slightly higher than for the industry overall, accounting for 81 
percent of total U.S. midstream merger activity. Over the period, the 
number of midstream mergers varied somewhat, from a low in 2000 of 6 
mergers, to a high in 2005 of 26 mergers (see fig. 6).

The top reported transaction values for midstream mergers were the 
lowest of the three segments, with the most valuable midstream merger 
totaling $2.8 billion, and a total of eight midstream mergers that 
exceeded $1.0 billion (see table 3). Overall, the average midstream 
merger was valued at $252 million, while the median value was $92 
million. Looking at the subsegment level, merger activity was split 
fairly evenly across the pipelines and tankers/other transportation 
subsegments, with pipelines accounting for 47 percent of mergers and 
tankers/other transportation accounting for 53 percent.

[End of table] 

In the midstream segment, industry representatives reported that U.S. 
mergers have been driven in part by the desire to improve the overall 
financial performance of midstream operators.[Footnote 19] According to 
one industry report, developments in recent years have prompted a 
renewed focus on risk mitigation and portfolio management in the 
midstream segment, thereby prompting pipeline and other midstream 
operators to pursue merger activity. The industry report also noted 
that midstream merger activity has been further encouraged by the 
increased involvement of investment banks and the availability of 
private equity in such endeavors. Furthermore, a government report 
noted that reduced domestic production of oil has created excess 
capacity for many U.S. pipelines, which, according to one firm, has 
prompted pipeline operators to pursue mergers as a means to remain 
economically viable. 

Downstream Segment: 

In the U.S. downstream petroleum segment, trends generally followed 
those for mergers overall, with asset mergers, comprising approximately 
73 percent of all downstream U.S. mergers and the annual number of 
mergers rising from 27 to 32 mergers from 2000 to 2006. Top transaction 
values for the downstream segment fell between those for the upstream 
and midstream segments, with the largest downstream merger valued at 
$9.8 billion, for the Phillips Petroleum Company and the Tosco Corp. As 
shown in table 4, the top 6 downstream mergers each totaled over $5 
billion in transaction value.

Looking at downstream mergers by subsegment, the terminals/storage 
subsegment drove the most merger activity, totaling 37.5 percent of 
mergers during this period (see fig. 7). Second to terminals/storage, 
the refining subsegment totaled 21.5 percent of all the downstream 
mergers that we examined, followed by mergers in the gasoline service 
stations subsegment at 16.0 percent.

[End of figure] 

In the downstream segment, industry officials reported that key drivers 
of U.S. mergers included a need to increase efficiencies and costs 
savings in the petroleum refining and marketing segments. On the 
refining end, industry officials reported that mergers can help achieve 
operational efficiencies through the integration of refinery operations 
and infrastructure. For example, officials reported that a larger 
refinery system allows firms to use feedstocks and blending stocks 
across refineries, which can improve efficiencies at individual 
refineries. In addition, industry representatives reported that 
purchasing crude oil for multiple facilities can allow refiners to 
secure volume discounts that yield cost savings. On the marketing end, 
industry representatives reported that mergers can better position 
marketers for competition through economies of scale and improved 
efficiencies. According to one industry official, refiners prefer 
larger marketers because (1) they are usually a lower credit risk than 
their smaller counterparts and (2) it is more efficient to sell larger 
volumes of fuel through fewer entities, because transaction and 
administrative costs can be minimized. One marketer reported that, 
after mergers occurred, the larger refiners made it clear that they 
only wanted to deal with marketers that bought fuel in quantities above 
a certain minimum. Smaller marketers that were not able to meet these 
minimums found it difficult to compete, and many were subsequently 
purchased by other marketers. In addition, some marketer 
representatives with whom we spoke said that they operate on slim 
profit margins, as little as 1 cent per gallon, and the economies of 
scale that can be achieved via mergers help improve profitability. 
Despite the gains that mergers can provide in the downstream segment, 
as well as in the upstream and midstream segments, policy makers and 
industry officials reported that mergers can also allow companies to 
exercise market power and reduce competition in the industry. 

Market Concentration Changed Little, but Varied by Market Region and 
Industry Segment: 

We found that the upstream market segment for crude oil production was 
unconcentrated and remained so between 2000 and 2006. We looked at all 
the sellers that produce crude oil worldwide because the price of crude 
oil is set in global markets. We calculated each firm's relative market 
share of worldwide crude oil production and then calculated HHIs from 
2000 to 2006. We found relatively unconcentrated HHIs (i.e., below 
1,000 according to FTC's merger guidelines) in this segment of the 
industry and that these numbers remained stable over time, despite the 
mergers that occurred in this segment (see fig. 8). In addition, we 
found that individual crude suppliers throughout the world have 
relatively low market share compared with other suppliers worldwide. 
Even a relatively large producer such as Saudi Arabia had only about 13 
percent of global crude production in 2006, according to our analysis 
of Oil and Gas Journal data. However, the coordination among global 
crude producers that are members of the Organization of the Petroleum 
Exporting Countries cartel can contribute to their ability to exercise 
market power beyond what the market concentration figures would 
indicate.

Although global crude oil markets appear to be unconcentrated, in some 
instances smaller, landlocked refineries, such as those in Oklahoma, 
rely heavily on only local crude producers. Under these circumstances, 
the crude supplier market would be more concentrated, and there could 
be more potential for the crude producers to raise prices. We heard 
from some industry experts and one small, independent refiner that it 
can sometimes be difficult to purchase crude oil under these 
circumstances because of the limited choice of suppliers. 

We found that between 2000 and 2007, in the downstream gasoline 
refining segment, market regions in the United States were stable and 
generally moderately concentrated. We analyzed concentration in what 
experts consider key market regions: Los Angeles, San Francisco, the 
Gulf Coast, New York Harbor (East Coast), Chicago, Tulsa (or the Mid- 
continent), and the Pacific Northwest.[Footnote 20] Although 
concentration was generally moderate in these regions between 2000 and 
2007, the New York and San Francisco regions had concentrations above 
or near 1,800, which FTC considers highly concentrated (see fig. 9). 
Petroleum industry experts consider refinery market analysis 
particularly important because most U.S. refiners have minimal spare 
capacity, and the barriers to entry for new refiners are high.

Between 2000 and 2007, the HHI for the New York Harbor region increased 
from 1,630 to 2,104, but because foreign and Gulf Coast refineries ship 
a significant amount of gasoline into the East Coast (around 60 percent 
of consumption), the high measure of concentration probably overstates 
the actual concentration for the market.[Footnote 22] The potential for 
market power is likely lower than the HHI would indicate because 
refiners from outside of this region have the ability to challenge 
potentially anticompetitive behavior from local refiners over longer 
periods of time by providing lower-priced gasoline. Calculating HHI 
with these potential competing refiners included would provide a more 
accurate representation of concentration levels in this region. 

Between 2000 and 2007, the HHI for the Chicago region went from 1,417 
to 1,268, keeping it moderately concentrated throughout the period of 
our study. In addition, this region--which serves large parts of the 
Midwest, according to industry experts--also receives shipments of 
gasoline from the Gulf Coast via pipeline, and, according to our 
analysis of EIA data, shipments from outside of the region accounted 
for about 28 percent of the gasoline consumed in the Midwest region. 
[Footnote 23] This indicates that numerous refiners outside of the 
Chicago region help to keep the market supplied and could provide 
adequate gasoline to prevent long-run price increases. 

Between 2000 and 2007, the HHI for the Gulf Coast region, which 
includes refineries in Texas, Louisiana, and Alabama, went from 761 to 
938, an increase of 177 points. This region remained unconcentrated 
throughout our study period and has, by far, the greatest number of 
refineries. As a result, the Gulf Coast region generally produces more 
gasoline than it uses, and about two-thirds of it is shipped outside of 
the region,[Footnote 24] mostly to the Midwest and East Coast. 

Between 2000 and 2007, the HHI for the Mid-continent region went from 
1,029 to 882, a decrease of 147 points. This region became 
unconcentrated during our study period. However, some experts mentioned 
that some Mid-continent refineries in states such as Montana, Utah, and 
Wyoming primarily supply only their local regions, making these regions 
subject to potentially more highly concentrated local market conditions 
rather than lower concentrated regional Mid-continent conditions. 

In general, the West Coast of the United States was moderately 
concentrated. Between 2000 and 2007, the Pacific Northwest region was 
moderately concentrated, although the HHI increased 293 points, from 
1,146 to 1,439. In addition, the HHI for the San Francisco region 
remained in "nearly" highly concentrated territory over the entire span 
of our study. The HHI for the Los Angeles region went from 1,460 to 
1,285, keeping it firmly in the moderately concentrated range between 
2000 and 2007. As is the case with the New York Harbor region, West 
Coast regions have some access to imported gasoline, and gasoline can 
also move between West Coast regions. This clearly helps to mitigate 
potential issues of high concentration, according to experts with whom 
we spoke. Imports to California markets, however, are limited by the 
state's unique gasoline specifications and many refineries outside of 
the state are not able to produce gasoline for California. 

In our analysis of downstream wholesale gasoline suppliers, we found 
that most states had a moderately concentrated number of wholesale 
gasoline suppliers between 2000 and 2007. However, markets for 
wholesale gasoline marketing may not correspond to states; therefore, 
in some cases, the relevant geographic market would be either larger or 
smaller than state boundaries, according to some petroleum industry 
experts with whom we spoke. Fewer states were unconcentrated or highly 
concentrated, and this overall trend was fairly stable over time (see 
fig. 10). In addition, we found that eight states in 2007 were highly 
concentrated: Alaska, Hawaii, Indiana, Kentucky, Michigan, North 
Dakota, Ohio, and Pennsylvania (see fig. 11), although we were not able 
to link concentration levels to gasoline prices. To calculate these 
market concentrations for wholesale gasoline supply, we used EIA data 
that contained the gasoline volumes sold in every state, by wholesale 
supplier. EIA only collects these data by state.

[End of figure] 

We were not able to calculate market concentration in the midstream 
segment of the petroleum industry, which transports crude oil and 
refined products throughout the United States, because of a lack of 
comprehensive data on pipeline and barge ownership and associated 
transportation markets. In addition, many petroleum product pipelines 
are considered "common carriers"; therefore, they are subject to FERC 
rates if they cross state boundaries and state-mandated rates if they 
remain within state boundaries, which FERC officials told us limits the 
ability of pipeline owning firms to increase prices anticompetitively. 
However, in some cases, pipeline firms can apply for "market-based" 
rates, although they have to demonstrate to FERC that they ship fuel 
between locations where there are ample shipping alternatives. This is 
not very often the case, and, according to FERC officials, there are 
few pipeline firms that charge market-based rates as a result. 

However, despite the lack of data, experts raised some important 
considerations regarding competition in the midstream segment. For 
example, petroleum marketers told us that in some instances, pipeline 
firms also own the terminals that connect to their pipelines and have 
the ability to set their own prices for fuel storage or other terminal- 
related services, potentially leaving shippers with few alternatives 
but to pay. In addition, according to some oil industry experts with 
whom we spoke, some pipeline companies are master limited partnerships-
-publicly traded limited partnerships, not subject to corporate income 
tax--which may have little interest in the long-term viability of their 
business, and, according to some industry experts with whom we spoke, 
may defer maintenance and limit increases in pipeline capacity to 
maximize profits in the short term. We noted in a 2007 report on energy 
markets that, in some states, such as Arizona, California, Colorado, 
and Nevada, there was a systemic lack of pipeline capacity that was 
insufficient in meeting increases in demand, creating conditions of 
higher prices and price volatility.[Footnote 25] Like refining, 
midstream infrastructure often has very high barriers to entry, thereby 
making it difficult for new competitors to enter the market. For 
example, it is difficult to get regulatory permits to build or expand 
pipelines, and the costs can run $1 million or more per mile, according 
to pipeline companies and other industry experts. 

FTC Primarily Reviews Proposed Mergers to Maintain Petroleum Industry 
Competition, While FTC and Other Agencies Also Have Roles in Monitoring 
Petroleum Industry Markets: 

FTC primarily reviews proposed mergers to maintain competition in the 
petroleum industry, while other federal and state agencies, including 
FTC, have roles in monitoring petroleum industry markets. FTC does a 
review to predict the effects of proposed mergers on competition, but 
generally does not look back to evaluate the actual effects after the 
merger has been completed, even though experts and FTC agree that 
postmerger reviews would allow the agency to better inform future 
merger reviews and to better measure its success in maintaining 
competition. In addition, the agency also conducts other activities to 
monitor petroleum product markets, such as monitoring wholesale 
gasoline prices for evidence of unusual price spikes. Other federal and 
state agencies also have roles in monitoring petroleum industry 
markets. 

FTC Reviews Proposed Mergers, but Does Not Regularly Review the Effects 
of Past Merger Decisions: 

In reviewing proposed mergers, FTC follows guidelines that it developed 
jointly with DOJ for predicting the effects of mergers--including 
petroleum industry mergers--on competition. The unifying theme in the 
guidelines is that mergers should not be permitted to enhance a firm's 
market power or to make it easier for a firm to exercise market power. 
The guidelines describe the analytical process that FTC will use in 
determining whether to challenge a merger, and they outline five broad 
areas for FTC to consider: (1) defining markets and analyzing 
concentration, (2) predicting potential adverse effects on competition, 
(3) evaluating barriers to new market entrants, (4) evaluating 
potential gains in efficiency, and (5) giving consideration to 
potentially failing firms. We discuss these five areas in the following 
text: 

Defining markets and analyzing concentration: FTC initially defines 
merging companies' markets and analyzes their market concentration. To 
do this, FTC first reviews merging firms' products; identifies any 
similar products they sell; and identifies the geographic markets in 
which the firms operate, which it defines as the area in which a 
company could monopolize the market and impose a small price increase 
without competing firms bringing prices back down by adding supply to 
the market. FTC then determines the industry market share--the 
percentage of products that companies supply to one geographic market 
area--and calculates an index of market concentration, HHI, where firms 
with larger market shares are weighted more heavily. If the proposed 
merger were to substantially raise HHI, there would be a greater 
likelihood that one firm, or a small group of firms, could exercise 
market power and increase consumer prices above competitive levels. 
This situation may trigger FTC to request more information from the 
merging firms to look more closely at several factors affecting market 
competition (see table 5). 

Table 5: FTC's Concentration Guidelines for Initial Analysis of 
Proposed Mergers: 

Postmerger HHI: Less than 1,000; 
Degree of market concentration: Unconcentrated; 
Change in HHI that would result from the proposed merger: Not 
applicable; 
Potential competitive consequences and likely need for further DOJ/FTC 
analysis: Ordinarily no further analysis. 

Postmerger HHI: Between 1,000 and 1,800; 
Degree of market concentration: Moderately concentrated; 
Change in HHI that would result from the proposed merger: Increase 
<100; 
Potential competitive consequences and likely need for further DOJ/FTC 
analysis: Ordinarily no further analysis. 

Postmerger HHI: Between 1,000 and 1,800; 
Degree of market concentration: Moderately concentrated; 
Change in HHI that would result from the proposed merger: Postmerger 
HHI Greater than 1,800: Increase >100; 
Potential competitive consequences and likely need for further DOJ/FTC 
analysis: Could raise significant competitive concerns, depending on 
other factors. 

Postmerger HHI: Greater than 1,800; 
Degree of market concentration: Highly concentrated; 
Change in HHI that would result from the proposed merger: Increase <50; 
Potential competitive consequences and likely need for further DOJ/FTC 
analysis: Ordinarily no further analysis. 

Postmerger HHI: Greater than 1,800; 
Degree of market concentration: Highly concentrated; 
Change in HHI that would result from the proposed merger: Increase >50; 
Potential competitive consequences and likely need for further DOJ/FTC 
analysis: Could raise significant competitive concerns, depending on 
other factors. 

Postmerger HHI: Greater than 1,800; 
Degree of market concentration: Highly concentrated; 
Change in HHI that would result from the proposed merger: Increase 
>100; 
Potential competitive consequences and likely need for further DOJ/FTC 
analysis: Likely to create or enhance market power or facilitate its 
exercise. 

Sources: FTC and DOJ. 

Note: FTC staff told us that they do not ordinarily conduct further 
analysis in the specific HHI regions listed in this table, but they can 
do so if there are other factors that indicate a merger would likely 
harm competition. 

[End of table] 

Predicting potential adverse effects on competition: FTC's second step 
is to predict the nature of adverse effects of a merger on competition 
in the petroleum industry. To do this, FTC examines whether market 
conditions would be conducive for firms to coordinate or to act 
unilaterally to raise prices. The analysis of competitive harm at the 
retail level might involve looking for the presence of firms with 
different business models than their rivals, which would indicate less 
likelihood for coordination. For example, FTC noted that the presence 
of "big-box" retailers that sell discount gasoline and groceries, such 
as Costco or Wal-Mart, generally boost competition because they tend to 
sell large volumes of fuel at lower prices than traditional service 
stations. FTC might allow a merger to take place in a retail market 
with a large number of such retailers that it would otherwise challenge 
in a different market. 

Evaluating barriers to entry for new market entrants: FTC's third step 
is to evaluate the barriers to market entry for potential new 
competitors. When FTC identifies that it is unlikely that new firms 
could enter a market in a relatively short time, they consider the 
market to be less competitive and, therefore, would be less likely to 
approve a merger. FTC staff told us the petroleum industry is generally 
hard to enter because of the high capital costs; for example, building 
a new refinery could take 6 years and cost $10 billion, according to 
estimates for one proposed new facility. In general, FTC staff told us 
that because of factors like the high barriers to entry in the 
petroleum industry, they challenge mergers at lower levels of 
concentration than they do in other industries. As a result, the FTC 
staff said that they scrutinize the petroleum industry more closely 
than other industries, while still using the same merger review 
guidelines. 

Evaluating potential gains in efficiency: FTC's fourth step is to 
evaluate any claims from the merging parties' that the merger would 
improve efficiency in the petroleum industry. For example, some mergers 
have the potential to make the merged firms more efficient in their 
daily operations by allowing them to achieve economies of scale, and 
this may result in lower prices for consumers. If FTC determines that a 
merger could result in substantial efficiency gains, it may allow a 
merger that would otherwise potentially harm consumers. However, the 
guidelines acknowledge that these efficiency gains may not be realized 
in the way that merging firms claim. 

Considering potential failing assets argument: FTC's fifth step is to 
evaluate whether the merger will result in a firm remaining in the 
market that would have otherwise gone out of business. FTC would be 
less likely to challenge such a merger if it would allow a firm to 
remain a viable market participant, according to FTC staff with whom we 
spoke. 

To determine the extent of the competitive factors that we have 
previously discussed, FTC staff told us they work closely with 
petroleum industry participants, often review thousands of pages of 
evidence, and work with antitrust officials in the states affected by 
the merger. The merger review process could last under 30 days if the 
agency does not request additional information from the merging 
parties; however the process could last 12 months or more if extensive 
analysis is needed and the agency issues a second request for more 
information, according to FTC staff. After analysis of the factors in 
the guidelines, FTC has three options: (1) allow the merger; (2) 
challenge the merger in court; or (3) allow the merger with certain 
remedial actions, such as requiring firms to sell off, or divest, 
overlapping assets that have the greatest potential to harm 
competition. For example, in the petroleum industry, this might mean 
requiring one of the merging firms to sell a product terminal in an 
area where the merging partner owns one. 

According to FTC data, between 2000 and 2007, there were 360 mergers in 
the petroleum industry that were required to file with the agency. 
[Footnote 26] After reviewing these proposed mergers, FTC opened 
investigations in 64 mergers and issued second requests in 24 of them. 
FTC allowed 9 mergers to proceed with remedial actions, while the 
threat of agency challenges led to the abandonment of 5 of them. FTC 
allowed the rest to proceed without modification. To make these 
decisions, FTC performed prospective merger reviews to predict the 
effects of the mergers before they were completed. However, we found 
that after reviewing proposed mergers, FTC does not regularly look back 
at past decisions to determine the actual effects of the merger on 
competition or prices. In 2004, we reported that FTC had released its 
first retrospective review[Footnote 27] of any kind for approved 
mergers in the petroleum industry.[Footnote 28] FTC has since released 
two additional retrospective reviews of petroleum industry mergers. The 
first one, in 2004, was of a 1998 joint venture between Marathon Oil 
Company and Ashland Incorporated; the second one, in 2005, was of a 
1999 acquisition of Ultramar Diamond Shamrock Corporation by Marathon 
Ashland Petroleum; and the third one, in 2007, was of the 1997 
acquisition of Thrifty Oil Company by ARCO. According to its published 
reports on these studies, FTC chose to review these mergers because 
evidence suggested there was a chance that they might have led to 
higher gasoline prices in areas affected by the mergers. None of the 
studies found that the mergers had any adverse effects on gasoline 
prices, although FTC indicated that the studies provided important 
lessons that would inform their future merger review work. 

A number of petroleum industry experts, industry participants, and FTC 
all view retrospective merger reviews as a potentially valuable part of 
FTC's efforts to maintain competition in the petroleum industry. An FTC 
commissioner, who is now the FTC Chairman, noted in a 2006 article that 
without retrospective reviews, it is rarely possible to determine 
whether the assumptions and hypotheses that motivated a merger review 
decision were sound.[Footnote 29] Some experts also noted that 
examining mergers retrospectively can provide valuable insights that 
FTC can apply during subsequent merger reviews. Specifically, 
retrospective reviews bring to light any effects that do not occur as 
predicted. For example, a study that FTC published in 1999 looked back 
at a number of cases where it had required divestitures in a variety of 
industries and found that only three-quarters of divestitures succeeded 
to some degree, which would leave fewer competitors than predicted and 
potentially harm competition. In addition, as noted in FTC and DOJ's 
Merger Guidelines, efficiency gains that could mitigate the harmful 
effects of a merger may not always be realized. Retrospective reviews 
would allow FTC to identify such situations, and this could help inform 
the agency's future merger reviews. 

FTC staff told us that if they find anticompetitive behavior in 
retrospective reviews, they have the ability to pursue corrective 
action to reintroduce competition into the market. For example, FTC has 
the power to pursue actions, such as forced divestures or conduct-based 
remedies, to bring competition back into the market place. In fact, FTC 
has identified anticompetitive behavior in retrospective merger reviews 
it conducted in other industries and has taken corrective actions. In 
2005, FTC, using results from a retrospective review of a hospital 
merger in suburban Chicago, found that the merged hospital used market 
power to set prices in an anticompetitive manner.[Footnote 30] Using 
these findings, FTC filed suit and the courts issued numerous cease-and-
desist orders to the hospitals, which brought price competition back 
into the healthcare market according to FTC staff. 

In addition, some experts with whom we spoke said that retrospective 
merger reviews would allow FTC to better measure the success of its 
merger review program. The Government Performance and Results Act of 
1993 (GPRA)[Footnote 31] emphasizes that agencies need to establish and 
measure performance toward results-oriented goals, which in FTC's case 
means that the agency should not measure success by how many mergers it 
reviews, but rather by whether merger reviews achieved the goal of 
maintaining competition.[Footnote 32] Currently, FTC's key measure of 
its merger review performance is to determine the number and the value 
of potentially anticompetitive mergers that it successfully challenged. 
However, this measure does not involve an evaluation of mergers that 
ended up being harmful, but that the agency did not challenge after 
predicting they would be harmless. In addition, in cases where mergers 
proceed with remedial actions, FTC's key performance measure indicates 
a successful outcome, even though remedial actions, such as 
divestitures, may not always succeed. Using retrospective merger 
reviews to look at the actual effects of completed mergers on 
competition would better show whether the program achieved the goal of 
maintaining competition. 

However, FTC does not have--and does not plan to develop--formal 
guidelines or criteria on how often retrospective reviews should occur 
or how to conduct them, instead the agency relies on an informal 
approach. For example, staff reported that in the past two 
retrospective reviews, staff chose to review completed mergers that FTC 
subjected to careful antitrust investigation, but did not challenge; 
otherwise, there are no defined guidelines. In the absence of regular 
retrospective reviews, FTC may not be able to regularly apply lessons 
learned from past merger decisions to future reviews, assess the 
performance of its merger review program, or take remedial actions in 
instances where completed mergers ended up harming competition. FTC 
staff cited a lack of time and resources as the primary challenge to 
its ability to conduct retrospective reviews. Specifically, staff 
reported that it was difficult to devote the time and staff resources 
required to conduct these types of reviews, and stated that 
retrospective reviews of mergers in the petroleum industry are 
important, yet lower priority, compared with other mission-central 
activities, such as premerger reviews. In addition, according to 
economists with whom we spoke, developing the statistical models needed 
to conduct retrospective reviews is complex and time consuming. They 
indicated that there are numerous factors affecting the price of 
gasoline that must be controlled for in order to attribute any changes 
in price to a particular merger. Nonetheless, we have reported in prior 
work that agencies with limited resources can implement risk-based 
guidelines to selectively look back at agency decisions.[Footnote 33] 
Risk-based guidelines provide criteria for taking action based on the 
likelihood that agency goals were not met. These would allow FTC to 
selectively use resources to evaluate past merger decisions in 
circumstances where it deems there is greater likelihood, and hence 
risk, that the goal of maintaining competition was not met. 

FTC Performs Other Supplemental Activities to Monitor Petroleum 
Industry Markets: 

In addition to its efforts to maintain competition through merger 
review, FTC also performs other activities to monitor petroleum 
markets, including monitoring fuel prices, conducting special 
investigations, and engaging in consumer protection activities. FTC 
implemented a price-monitoring program in 2002 for wholesale and retail 
prices of gasoline in an effort to identify possible anticompetitive 
activities and determine whether a law enforcement investigation was 
warranted. The program tracks retail gasoline and diesel prices in 360 
cities across the nation and wholesale prices in 20 major urban areas. 
FTC's Bureau of Economics staff receives daily data from the Oil Price 
Information Service (OPIS), receives weekly information from the 
Department of Energy's public Gas Price Hotline, and reviews other 
relevant information that might be reported to FTC directly by the 
public or other federal or state government entities. FTC uses a 
statistical model to determine whether current retail and wholesale 
prices each week are consistent with historical patterns and to alert 
FTC staff when gasoline prices are out of expected ranges for that 
region. Staff can then conduct more in-depth analyses to determine 
whether there are violations of antitrust laws. Since its establishment 
in 2002, the price-monitoring program has not identified any price 
anomalies that would violate the antitrust laws; it attributes most 
price anomalies to refinery or pipeline outages or changes in air 
quality standards. FTC staff reported that outside economists and FTC 
staff reviewed the program's methodology and found it to be effective. 

FTC's staff indicated that they also conduct special investigations of 
the petroleum industry when warranted. Occasionally, such 
investigations are requested by Congress. For example, in 2006, the 
agency published a congressionally mandated report entitled 
Investigation of Gasoline Price Manipulation and Post Katrina Gasoline 
Price Increase that evaluated price anomalies after Hurricanes Katrina 
and Rita. This investigation did not find evidence of anticompetitive 
behavior in any of the industry segments during or after the 
disruptions. The agency also completed an investigation into gasoline 
and diesel prices in the Pacific Northwest in 2006 and 2007 that found 
prices appeared to be consistent with ordinary market conditions. In 
addition to their special investigations, the agency also publishes 
various reports on the petroleum industry that are, mainly, agency- 
driven. For example, in 2004, FTC published a report on mergers and its 
antitrust enforcement activities in the petroleum industry.[Footnote 
34] Furthermore, the Commission's Bureau of Consumer Protection has 
brought actions to protect consumers from false or unsubstantiated 
advertising claims regarding the effectiveness or energy-saving of 
fuels or automotive products. 

In addition, on August 13, 2008, FTC issued a proposed rule that would 
make it unlawful for any person to engage in fraudulent or deceptive 
acts in connection with the purchase or sale of crude oil, gasoline, or 
petroleum distillates to manipulate wholesale petroleum markets. 
Therefore, fraudulent or deceptive acts--including false reporting to 
private reporting services or misleading announcements by refineries, 
pipelines, or investment banks--may be covered by the proposed rule. 
However, it is not yet clear how this rule will impact FTC's 
enforcement or monitoring in petroleum industry markets. 

Other Federal and State Agencies Also Monitor Petroleum Industry 
Markets: 

Besides FTC, other federal agencies have a role in monitoring petroleum 
industry markets. Table 6 provides general examples of three federal 
agencies' responsibilities regarding petroleum markets. Some states are 
also involved in monitoring petroleum markets that affect their 
constituents. 

Table 6: Other Federal Agencies That Monitor Petroleum Industry Markets 
and Examples of Their Roles: 

Federal agency: Federal Energy Regulatory Commission; 
Examples of roles in monitoring petroleum industry markets: Determines 
pipeline shipping rates by regulating the terms of contracts for 
pipelines to create open access to all parties. 

Federal agency: Commodity Futures Trading Commission; 
Examples of roles in monitoring petroleum industry markets: Monitors 
futures markets to encourage their competitiveness and efficiency and 
to protect market participants against fraud, manipulation, and abusive 
trading practices. 

Federal agency: Energy Information Administration; 
Examples of roles in monitoring petroleum industry markets: Collects, 
analyzes, and forecasts petroleum data to allow for market monitoring, 
to promote sound policy making, and to create efficient energy markets.

FERC has a role in monitoring and regulating petroleum industry markets 
at the midstream level--where crude oil and petroleum products are 
transported--by ensuring that all parties have access to common-carrier 
pipelines.[Footnote 35] While FERC does not proactively monitor 
pipeline markets, it regulates the open access to pipelines by 
determining and enforcing tariffs--that is, the rates charged and the 
terms under which shippers send their products through the pipelines 
and the rules governing pipeline access. According to FERC officials, 
pipeline companies establish their initial rates either (1) by filing 
an application with FERC requesting a rate based on the total cost-of-
service for the pipeline or (2) by proving to FERC that shippers have 
agreed to pay another proposed rate. As we have previously discussed, 
FERC also allows some pipelines to charge market-based rates in regions 
where it deems there is adequate competition. FTC still has the 
authority to enforce antitrust legislation and review mergers to 
maintain competition in this segment of the industry. In some 
instances, FERC can also intervene to prevent potentially 
anticompetitive behavior. For example, FERC officials cited an instance 
where a pipeline company denied access to a crude oil producer who 
wanted to ship high sulfur crude oil out of the Gulf Coast. The 
pipeline company said that it did not want to have high sulfur crude 
contaminating its pipeline, although the shipper alleged that the 
pipeline company was acting in collusion with a rival crude oil 
producer by restricting access to the pipeline. After receiving the 
complaint, FERC officials worked with the parties to resolve the 
matter. 

The Commodity Futures Trading Commission (CFTC) monitors futures 
markets to ensure competitiveness and efficiency, and protects market 
participants against fraud, manipulation, and abusive trading 
practices.[Footnote 36] Participants in futures markets, such as the 
New York Mercantile Exchange, often use futures contracts,[Footnote 37] 
which contribute to the smooth functioning of petroleum product markets 
throughout the United States. Buyers and sellers in the futures markets 
primarily enter into futures contracts to lock in prices on volatile 
goods or to speculate rather than to exchange physical goods, which is 
the primary activity of the spot markets. 

CFTC has several divisions that monitor and enforce competition in the 
futures markets. The Division of Enforcement investigates and 
prosecutes alleged violations of the Commodity Exchange Act and 
Commission regulations. One example of market manipulation in the crude 
oil markets occurred in 2003, when one company attempted to manipulate 
the spot market price of West Texas Intermediate crude oil. The case 
was brought by CFTC and settled in 2007 for a $1 million civil penalty. 
In addition, CFTC has created advisory committees to provide input and 
make recommendations to the Commission on a variety of regulatory and 
market issues that affect the integrity and competitiveness of U.S. 
markets. These committees include an Energy Markets Advisory Committee 
that was created in 2008 to advise CFTC on important new developments 
in energy markets that may raise new regulatory issues, and on the 
appropriate regulatory response to protect market competition, increase 
efficiency, and create opportunities in the futures markets. 

The Department of Energy's EIA also has a role in analyzing and 
monitoring petroleum industry markets. Specifically, EIA collects, 
analyzes, and forecasts data on the supply, demand, and prices of crude 
oil and petroleum products, including inventory levels, refining 
capacity and utilization rates, and product movements into and within 
the United States. EIA's reports are prepared independently of 
Administration policy, and EIA does not provide conclusions or 
recommendations in its analyses. FTC relies on EIA's comprehensive and 
independent data and several state agencies with whom we spoke use 
these data to review mergers, conduct market concentration analysis, 
and analyze wholesale and retail gasoline markets. For example, FTC 
uses EIA data to support enforcement action cases and, in 2007, 33 
cases were pursued, the highest number of cases in the last 5 years. 
[Footnote 38] 

In addition to the agencies that monitor petroleum industry markets, 
the Environmental Protection Agency (EPA) also has a role in helping to 
maintain the flow of petroleum products during emergency supply crises 
by providing waivers for refineries to allow them to sell products that 
would not normally meet environmental standards. For example, after 
supply disruptions resulting from Hurricanes Katrina and Rita, EPA 
indicated that it met with local market participants and, following 
review of the market circumstances, granted waivers on environmental 
quality specifications. According to EPA, this ensured there were no 
regulatory obstacles to providing an adequate supply of gasoline and 
diesel to the affected regions. 

Most states do not proactively monitor petroleum industry markets, 
although the level of monitoring varies from state to state, according 
to the National Association of Attorneys General (NAAG). Some states do 
not monitor fuel prices or other aspects of the petroleum industry at 
all, while other states actively monitor market structure or fuel 
prices on a continual basis.[Footnote 39] Financial, political, and 
other factors may be the reason for whether and how actively states 
monitor petroleum industry markets. State agency officials with whom we 
spoke described a number of steps they can take in monitoring their 
petroleum industry markets. 

First, some states collect and analyze data on the industry--especially 
at the gasoline wholesale and retail levels. For example, after 
Hurricane Katrina, according to the Pennsylvania Office of Attorney 
General, the state decided to monitor retail gasoline prices during 
that period of reduced gasoline supply. The state ended up bringing 
charges against retailers that were allegedly setting unfair prices. 
States may also enact legislation to make it mandatory for companies to 
provide data on wholesale gasoline sales. For example, Maine 
implemented a statute called the Petroleum Market Share Act, which 
requires petroleum wholesalers and refiners to provide annual reports 
to the attorney general who uses this information to calculate market 
concentration for fuel suppliers, ensuring that the state has 
historical data to proactively track market concentrations. Second, 
states may enact legislation to prosecute unfair practices that lead to 
very high prices, that is, "price gouging." According to a study by the 
Congressional Research Service (CRS),[Footnote 40] at least 28 states, 
the District of Columbia, and 2 U.S. territories have some form of 
price gouging legislation, although several states we spoke with said 
it was generally difficult to prove that unfair pricing had occurred. 
Currently, there is no federal price gouging law, but the 110th 
Congress has proposed several bills that address the issue. Third, most 
of the states we contacted also develop gasoline pricing reports to 
inform the public of the changes in the petroleum industry. For 
example, the state of Washington published a comprehensive interagency 
report in 2008 to address how gasoline prices have increased over the 
years and identified in a comparative analysis the different components 
contributing to the rising prices. Finally, several states often 
collaborate with FTC on merger reviews because they have local 
knowledge of the companies and provide expertise that federal agencies 
may lack. For example, the California Attorney General has worked 
cooperatively with FTC to review a number of mergers, including large 
mergers such as the Exxon Mobil merger, and provided legal and 
technical expertise on the California market, such as knowledge of the 
intricacies of California pipelines. Overall, states are interested in 
improving their monitoring of petroleum industry markets in their 
areas, according to NAAG. 

Conclusions: 

Because there are few substitutes for transportation fuels such as 
gasoline, consumers have little choice but to pay higher prices when 
they rise. As a result, consumers want assurance that the prices they 
pay are determined in a competitive and fair marketplace. FTC plays a 
key role in maintaining petroleum industry competition and in assuring 
the public that mergers have not led to unfair price increases. 
Maintaining competition in the petroleum industry requires FTC to fully 
understand the effects of its merger decisions on competition and fuel 
prices. While FTC considers the potential effects of mergers during its 
proposed merger review, the agency does not routinely look back to 
determine whether the actual effects of the merger reflect what the 
agency predicted. It is possible that the actual effects of a completed 
merger could be different and not realized until much later. Without 
more regular retrospective reviews, the agency does not know whether a 
completed merger contributed to fuel price increases or decreases or 
whether the merger improved or harmed competition. In addition, FTC 
cannot apply lessons learned to future merger reviews and is unable to 
effectively monitor its own performance in delivering the intended 
result of "maintained" competition. We believe, along with the experts 
with whom we spoke, including those at FTC, that regular retrospective 
analyses would help the agency better understand the actual impacts of 
mergers. While not all completed mergers would likely warrant 
retrospective reviews, an approach that uses risk-based guidelines 
would allow the agency to selectively review key mergers with the goal 
of maintaining competition in the petroleum industry. 

Recommendations for Executive Action: 

To enhance FTC's effectiveness in maintaining competition in the U.S. 
petroleum industry, and to make efficient use of FTC's resources, we 
recommend that the FTC Chairman lead efforts to (1) conduct more 
regular retrospective analyses of past petroleum industry mergers and 
(2) develop risk-based guidelines to determine when to conduct them. 

Agency Comments: 

We provided a copy of our draft report to FTC for its review and 
comment. FTC's Chairman provided written comments, which are reproduced 
in appendix III, along with our responses. In general, the Chairman 
commented that the recommendations in this report were consistent with 
the goals outlined in FTC's current self-evaluation initiative, and 
that FTC would consider our recommendations to conduct more regular 
retrospective analyses of petroleum industry mergers using a risk-based 
approach along with other recommendations resulting from this 
initiative. The Chairman also noted that analyzing market concentration 
is just the starting point in FTC's antitrust analysis, and emphasized 
that each merger involves a unique set of facts and other competitive 
factors that the agency considers. He also noted the difficulties in 
delineating geographic antitrust markets, and we responded to each of 
these concerns in appendix III. We clarified other material in this 
report in response to technical comments by the Chairman as 
appropriate. 

We are sending copies of this report to interested congressional 
committees and the FTC Chairman. Copies of this report will be made 
available to others upon request. In addition, this report is available 
at no charge on the GAO Web site at [hyperlink, http://www.gao.gov].

Appendix I: Objectives, Scope, and Methodology: 

The objectives of this report were to examine (1) mergers in the U.S. 
petroleum industry and changes in market concentration since 2000 and 
(2) the steps that the Federal Trade Commission (FTC) uses to maintain 
competition in the U.S. petroleum industry, and the roles other federal 
and state agencies play in monitoring petroleum industry markets. 

To examine U.S. petroleum industry mergers since 2000, we primarily 
used merger data that we purchased from John S. Herold, Inc. (J.S. 
Herold), an independent research and consulting firm that collects data 
and conducts analyses for the energy sector. J.S. Herold collects 
information on all publicly announced mergers in the petroleum industry 
and records key financial and operational data about these mergers in a 
large database. Prior to purchasing information from this database, we 
assessed the reliability of these data and found them sufficiently 
reliable for the purposes of this report. The data purchased from J.S. 
Herold included extensive information on all petroleum industry mergers 
from 1991 through 2007, including but not limited to, company names, 
locations, merger values, and key assets involved in the mergers. The 
J.S. Herold data were limited to mergers that exceeded $10 million in 
value, and we limited our review to mergers that were principally 
located in the United States or that we had reason to believe involved 
U.S. locations.[Footnote 41] In addition, we excluded mergers whose 
main asset was natural gas or a natural gas product as well as mergers 
that occurred before 2000. For the remaining data, we conducted a 
variety of analyses to better understand merger activity. These 
analyses included, but were not limited to, evaluating the number, 
type, and transaction value of mergers over time as well as evaluating 
the distribution of mergers across industry segments and subsegments. 
To better understand and contextualize the results of our analysis of 
the J.S. Herold data, we also reviewed industry journal articles and 
conducted interviews with industry officials and experts to better 
interpret merger activity over time. 

To examine the rationale for petroleum industry mergers since 2000, we 
conducted interviews with various representatives from all three 
segments of the petroleum industry. For information on the upstream 
segment, we interviewed representatives from large, vertically 
integrated oil companies as well as a smaller, independent exploration 
and production company. For information on the midstream segment, we 
primarily relied on industry publications because midstream operators-
-including pipeline and tanker operators--were less available for 
interviews or comment. For information on the downstream segment, we 
interviewed representatives from vertically integrated companies. In 
addition, we interviewed a number of other firms operating in the 
downstream segment, including refiners, marketers, and retailers of 
petroleum. To better contextualize the information provided in these 
interviews, we also conducted a literature search of articles that 
addressed rationales for petroleum industry mergers from 2000 through 
2007. Lastly, we interviewed a number of experts--including academics 
specializing in the petroleum industry or antitrust matters as well as 
industry representatives--for additional context and information on 
recent merger activity. 

To calculate market concentrations (HHI) at the upstream level, we 
purchased data from the Oil and Gas Journal containing crude oil 
production information for the 100 largest international companies 
between 2000 and 2006. These data included state-owned oil companies, 
such as those in Iran and Saudi Arabia. After conducting data 
reliability assessments, such as looking for out-of-range and missing 
values, we found these data to be sufficiently reliable for our use in 
calculating upstream HHI. We used a single global market to calculate 
HHI in this segment because, according to experts with whom we spoke, 
crude oil prices are set on world markets. 

Because of the lack of readily accessible data on the midstream 
petroleum industry, which simultaneously includes the pipeline, barge, 
and trucking industries, we were not able to calculate HHI in this 
segment. 

To calculate HHI for the refining segment we defined geographic markets 
(see app. II for more details on how we defined geographic markets), 
and then estimated the gasoline production capacity of United States 
refineries by using annual data from EIA that contained capacity 
information for refineries in the United States and the Caribbean. 
After conducting data reliability assessments, such as looking for out- 
of-range and missing values, we found these data to be sufficiently 
reliable for our use in calculating HHI. 

After discussions with the Department of Energy's Energy Information 
Administration (EIA), we chose to look specifically at the capacity of 
the following three units that account for most gasoline production 
capacity at U.S. refiners: 

1. Catalytic reformer. 

2. Fluid catalytic cracker. 

3. Alkylation unit. 

Because, according to EIA, two of these three units do not exclusively 
contribute to gasoline capacity, we had to adjust their output values 
in the data. For example, according to EIA estimates, only about 65 
percent of fluid catalytic cracker (FCC) output is likely to contribute 
to gasoline capacity, while 90 percent of a catalytic reformer's output 
is likely to contribute to gasoline capacity. These values can vary 
from refinery to refinery, but they were sufficient for our purposes. 
Footnote 42] For most refineries, we followed EIA's guidance and 
multiplied the capacity of the catalytic reformer by 0.9, the capacity 
of FCC by 0.65, and the capacity of the alkylation unit by 1.0. 
[Footnote 43] By summing these three values, we were able to estimate 
the relative gasoline production capacity of each refinery. [Footnotes 
44 and 45] 

EIA completed the HHI calculations for wholesale gasoline suppliers at 
the state level for us, due to the proprietary nature of these data. 
EIA used its prime supplier data to make these calculations, which 
contain the gasoline volumes sold in every state by wholesale supplier. 
[Footnote 46] After discussions with EIA officials, we found these data 
to be sufficiently reliable for EIA to calculate HHI for us. 

To examine FTC's processes for ensuring competition in the petroleum 
industry, we interviewed FTC staff on several occasions regarding their 
merger review procedures. In addition, we asked FTC staff a series of 
questions in writing, and they provided us with detailed written 
responses. We also analyzed a number of official agency documents. 
Finally, we interviewed experts in the fields of antitrust and 
industrial organization, and petroleum industry officials who provided 
us with comments on FTC's merger review procedures. 

To identify federal and state agencies' role in monitoring petroleum 
industry markets, we conducted interviews and reviewed studies and 
reports from several federal and state agencies. We chose certain 
federal agencies to be studied on the basis of their regulatory 
involvement with the various segments of the petroleum industry. We 
contacted the Federal Energy Regulatory Commission, Commodity and 
Futures Trading Commission, Environmental Protection Agency, Department 
of Transportation, Department of Energy, EIA, and Federal Maritime 
Commission because of their potential involvement in monitoring 
petroleum industry markets. We reviewed the federal agency Web sites, 
press releases, and reports published by these agencies before the 
interviews to understand their role in monitoring the petroleum 
industry markets and whether they would be good resources for further 
exploration. We conducted interviews with several federal officials 
from the aforementioned federal agencies. The questions were tailored 
to effectively obtain the information necessary to understand their 
involvement in monitoring. 

To identify state agencies' role in monitoring petroleum industry 
markets, we conducted interviews and reviewed studies and reports from 
several state attorneys general and energy-specific agencies. We chose 
the states to be studied on the basis of whether we thought they (1) 
had significant crude oil extraction and production; (2) had numerous 
refineries; (3) had isolated markets; (4) had coastal port terminals; 
and (5) were, according to expert opinion, progressive or proactive, or 
both, in monitoring competition in the segment of the petroleum 
industry active in their state. We also wanted to make sure that we had 
adequate geographic coverage of the country. The selected state 
attorneys general were from Alaska, California, Connecticut, Louisiana, 
Maine, New York, Pennsylvania, Texas, and the state of Washington. 
During the interviews with the selected states, we conducted a snowball 
sample where we asked our many interviewees if they knew of other 
states that had proactive market monitoring. We also asked if their 
state had an energy commission or another authority to monitor the 
petroleum industry. We also interviewed an official with the National 
Association of Attorneys General (NAAG), who catalogues information on 
individual state roles in monitoring petroleum industry competition. 
Before each interview, we reviewed the state agency Web sites, press 
releases, and reports published by the agencies and developed 
semistructured questions that addressed monitoring petroleum industry 
markets. 

We conducted this performance audit from March 2007 to September 2008 
in accordance with generally accepted government auditing standards. 
Those standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives. 

[End of section] 

Appendix II: Defining Geographic Refinery Markets: 

To define geographic refinery regions for the purposes of calculating 
HHI, we collaborated with staff from the Oil Price Information Service 
(OPIS), EIA, and FTC who had expertise on petroleum product markets, 
and who helped us to assign individual refineries to market regions. 

Our methodology used "spot markets" as the basis for defining 
geographic refinery regions. Spot markets reflect the historical 
grouping of U.S. refineries into seven refining centers. Energy traders 
consider gasoline available for delivery at these refining spot markets 
in order to price gasoline that is bought and sold at the wholesale 
level, and gasoline production in these refining groups drives prices 
on the spot markets. The seven spot markets in the United States, which 
we used as our refinery regions, are in Los Angeles, San Francisco, the 
Gulf Coast, New York Harbor, Chicago, Tulsa (or Mid-continent), and the 
Pacific Northwest. Most refineries in each region are able to supply 
gasoline to the larger geographic region that surrounds them, which 
also includes areas to which they are linked via pipeline.[Footnote 47] 
In addition, gasoline can flow between regions, although, according to 
experts with whom we spoke, under normal market conditions (i.e., 
absent a supply disruption, such as a hurricane) refiners are usually 
unable to ship gasoline to other regions in short notice to discipline 
the market because of the following reasons: 

* Gasoline specifications in one region may not be suitable for other 
regions. 

* Many refiners operate at near maximum capacity and may not have the 
ability to increase production to meet additional demand in other 
markets. 

* Transportation options between regions may be nonexistent or too 
costly to ensure a profit with only small price differentials between 
gasoline in each region. 

* When pipelines are present, it may not be feasible to use them 
because of the following: 

* The refinery may not have a link to the pipeline. 

* The refinery may not have the rights to an adequate allocation of 
pipeline space. 

* It may take too long for gasoline shipped via pipeline to arrive in 
another region, and experts with whom we spoke said that the industry 
is reluctant to respond to what it often perceives as temporary price 
increases. 

Despite these factors that support using spot markets as the basis for 
geographic refinery regions, there are still limitations. For example, 
according to experts, there are certain areas of the country where 
isolated refiners cannot send gasoline to any of the seven spot market 
centers and end up selling it locally, which suggests that there are, 
in addition to the seven spot markets, other smaller local refinery 
markets. Experts from EIA, FTC, and OPIS, mentioned that refineries in 
states like Alaska and Hawaii primarily supply their local regions, 
making them more subject to local market conditions, rather than larger 
regional factors. As a result, we removed these refineries from our 
calculations.[Footnote 48] In a number of cases, we counted a refinery 
in two spot markets. For example, according to the experts with whom we 
spoke, refineries in Bakersfield, California, can supply either the San 
Francisco region or the Los Angeles region.[Footnote 49] However, 
according to one OPIS official, gasoline suppliers still tend to 
predict their future fuel costs based on prices in one of the seven 
regional spot markets that we described, even though the fuel they buy 
may come only from a local refinery. In addition, FTC staff indicated 
that for merger review purposes, they would define more specific 
geographic markets, often using private company data, although they 
indicated that the markets we defined here are still useful for looking 
at U.S. refinery market concentration more broadly.

Appendix III: Comments from the Federal Trade Commission: 

Note: GAO comments supplementing those in the report text appear at the 
end of this appendix. 

Federal Trade Commission: 
The Chairman: 
Washington, DC 20580: 

September 17, 2008: 

Mr. Mark E. Gaffigan: 
Director, Natural Resources and Environment: 
United States Government Accountability Office: 
Washington, D.C. 20548: 

Mr. Thomas McCool: 
Director, Center for Economics Applied Research and Methods: 
United States Government Accountability Office: 
Washington, D.C. 20548: 

Dear Messrs. Gaffigan and McCool: 

The Federal Trade Commission ("FTC" or "Commission") is grateful for 
the opportunity to comment on the draft report submitted by the 
Government Accountability Office ("GAO") to the Commission on September 
2, 2008, and entitled: Energy Markets: Analysis of More Past Mergers 
Could Enhance Federal Trade Commission's Efforts to Maintain 
Competition in the Petroleum Industry (GAO-08-1082) ("Report"). The 
Report discusses market concentration in various segments of the 
petroleum industry from 2000 to 2007 and the steps the FTC takes to 
maintain competition in the petroleum industry. [Footnote 50] 

The Commission staff has been pleased to work with GAO staff conducting 
this review since March 2007, by providing information and discussing 
the processes that the Commission uses in reviewing mergers and 
acquisitions in the petroleum industry.[Footnote 51] The Commission 
believes that the Report will add to the understanding of the complex 
petroleum industry and the Commission's role in enforcing the antitrust 
laws related to mergers in that industry. Finally, as discussed in more 
detail below, the Commission thinks that GAO's recommendation that the 
FTC conduct regular reviews of some past petroleum mergers using risk-
based criteria is consistent with the Commission's self-evaluation 
initiative currently underway in connection with the upcoming 100th 
anniversary of the Commission's creation. The Commission provides below 
more detailed comments on the draft Report.[Footnote 52] 

I. Comments On The GAO Report: 

Description of the Petroleum Industry and Mergers in the Petroleum 
Industry: 

GAO's purpose in looking at the industry was to describe the general 
competitive status of the petroleum industry for the period 2000-2007. 
The Report describes segments of the petroleum industry and concludes 
that concentration has not changed significantly during the period 
January 2000-May 2007. 

Concentration is just the starting point for the Commission's antitrust 
analysis of a merger or acquisition. [See comment 1] The Commission 
notes that when it describes a petroleum market for antitrust law 
enforcement purposes, the Herfindahl-Hirschman Index ("HHI") numbers 
must relate to a relevant antitrust market. HHI numbers that do not 
describe relevant antitrust markets have little competitive 
significance. Even in properly delineated antitrust markets, the 
Commission would look beyond the HHI numbers to the competitive 
behavior of the participants in a given market and several other 
factors, including, but not limited to, barriers to entry and product 
differentiation, in order to determine whether the antitrust laws have 
been violated. As modem District Court and Court of Appeals decisions 
have emphasized, using HHI numbers alone to assess the competitiveness 
of a petroleum market sector provides a one-dimensional view rather 
than the multifaceted picture required for a thorough analysis of 
competitive conditions in a market. Before the Commission could draw 
any conclusions about the competitive effects of a particular merger, 
the law would also require the Commission to examine, among other 
things, the barriers to entry, the relationship of the players in a 
given market, and how closely the merging parties' products or services 
can substitute for one another. Accordingly, the Report's utility as a 
guide to conducting an antitrust assessment of a specific market or 
transaction is constrained. [See comment 1] 

Description of the FTC's Processes in Reviewing Petroleum Mergers and 
Monitoring the Industry: 

The Report describes five steps that the FTC takes in reviewing 
petroleum mergers: (1) defining markets and analzying competition; (2) 
predicting potential adverse effects on competition; (3) evaluating 
barriers to entry for new market entrants; (4) evaluating potential 
gains in efficiency; and (5) considering potential failing assets. The 
Report does not make clear that each merger involves a unique set of 
facts particular to that transaction, or that the factors to be 
analyzed in an antitrust evaluation of a merger - market concentration, 
barriers to entry, efficiencies, etc. - may vary in relative 
significance in each case. For example, the Report uses the HHI 
extensively to describe the markets and the first step of the FTC 
analysis. This measure of concentration is used only very initially in 
the antitrust analysis of a merger and may not play a determinative 
role in the final analysis. See, e.g., Commentary on the Merger 
Guidelines 2 (Mar. 2006), available at [hyperlink, 
http://www.ftc.gov/os/2006/03/CommentaryontheHorizontalMergerGuidelinesM
arch2006.pdf]. [See comment 2] 

For example, the Report identifies seven U.S. "spot market" regions in 
which to evaluate changes in concentration. As the Report correctly 
notes, these regions do not correspond to properly delineated antitrust 
geographic markets. In other words, the refining regions described in 
the Report should not be read to suggest that one of these regions is 
more or less likely to include the indicia required to demonstrate that 
any potential merger may have adverse competitive effects. 
Significantly, the refiners GAO associates with the New York region do 
not include a large number of actual and potential suppliers of bulk 
gasoline shipments that would affect the NY Harbor spot price data used 
in the Report. Moreover, although GAO also identifies states as 
geographic markets for wholesale supply, relevant wholesale markets are 
unlikely to conform with state boundaries. In some situations, 
wholesale markets may consist of only a part of a state; in other 
cases, they may consist of at least parts of more than one state. [See 
comment 3] 

To the extent that appropriate product and geographic markets are 
defined, other factors significant to competitive outcomes seem to be 
ignored if the analysis relies too heavily on simple concentration 
measures. [See comment 1] For example, despite a seemingly significant 
market share based on a first-cut HHI measurement, a competitor that 
cannot expand its output in response to a price increase may have very 
limited significance as a constraining factor in the market. In this 
case, the HHI may severely understate a merger's competitive 
significance. On the other hand, consider a market that allows quick 
and easy access by suppliers from outside the market; players that have 
a very small market share but an ability to provide additional product 
in response to a price increase could have a significant effect in 
constraining the behavior of market participants. In yet another 
scenario, a merger between parties with significant shares could pose 
little antitrust concern where the products offered by each firm are 
highly differentiated from each other. Market differentiation affects 
the ability of one firm to substitute its product for another in a 
given market. This condition would mitigate concern arising from a 
simple calculation of market shares in an undifferentiated market. In 
sum, HHIs or other arithmetic measures of market concentration may end 
up playing minor roles in the overall analysis in such instances. [See 
comment 1] 

Generally, steps 4 and 5 as described in the GAO Report (efficiencies 
and failing assets) are defenses that the merging parties raise in 
response to evidence that suggests that the merger may be 
anticompetitive. For example, if the FTC is convinced that efficiencies 
produced by the merger outweigh its potential harm, or if the acquirer 
provides the least anticompetitive acquisition of a failing firm that 
would prevent its assets from exiting the market, these factors may 
shift the balance in determining whether the merger would potentially 
violate the antitrust laws. 

Other Considerations: 

Footnote 15 to GAO's draft Report mentions that the FTC can - and 
does - challenge mergers that are not subject to the Hart-Scott-Rodino 
("HSR") Act's filing requirements. This point deserves greater 
emphasis, because some large transactions can escape the HSR filing 
requirements because of the structure of the transaction. In addition, 
the FTC sometimes investigates mergers between firms that operate in 
different, but related, segments of the industry. This concept also is 
not captured in GAO's analysis of the market segments. [See comment 1] 

The Gasoline and Diesel Price Monitoring Project: 

The Report also recognizes that the Commission staff monitors petroleum 
industry markets. The methodology that the staff uses in the Gasoline 
and Diesel Price Monitoring Project was extensively reviewed by FTC 
staff (including the Director of the Bureau of Economics) and by 
several outside economists, as noted in staff's written response to GAO 
questions on that Project. 

Retrospective Reviews of Petroleum Mergers: 

Since 2004, the Commission staff has released publicly three 
retrospective reviews of petroleum mergers.[Footnote 53] FTC staff 
chose to review the 1998 joint venture between Marathon and Ashland, 
the 1999 acquisition of Ultramar Diamond Shamrock by Marathon Ashland 
Petroleum, and the 1997 acquisition of Thrifty Oil Company by ARCO. FTC 
staff chose to review these acquisitions because these transactions' 
structural impact suggested the potential for significant competitive 
concerns or because commenters suggested that they possibly had led to 
higher gasoline prices in the geographic areas affected by the mergers. 
The studies found, however, that none of the mergers had any adverse 
effect on gasoline prices. 

The Report notes that not all consummated mergers would likely warrant 
retrospective reviews. We agree. As discussed below, the Commission's 
current self-evaluative initiatives cover not only petroleum mergers 
but all of the Commission's activities. 

II. The FTC'S Continuing And Evolving History Of Self-Evaluation: 

The Commission's Self-evaluative Initiatives: 

The Commission is first and foremost a law enforcement agency. Its 
primary task is to enforce the laws with respect to both competition 
and consumer protection. The Commission also recognizes that the design 
and implementation of future law enforcement efforts can benefit 
substantially from efforts to evaluate past enforcement decisions. As 
indicated below, the Commission actively seeks to achieve a sensible 
balance in the allocation of its resources between law enforcement and 
other activities, including retrospectives as part of its self-
evaluation process. 

Beyond the three Bureau of Economics retrospectives on the petroleum 
industry mentioned above, the Commission has a longstanding history of 
evaluating its activities, particularly with respect to antitrust law 
enforcement in the merger area.[Footnote 54] For example, in 1999 the 
Commission authorized release of the staff report, A Study of the 
Commission's Divestiture Process, which examined Commission orders 
issued from 1990 to 1994 that required divestiture to remedy the 
anticompetitive effects resulting from a merger. The study recommended 
a number of changes in the FTC's divestiture process and divestiture 
order provisions. Following this effort, the Commission continued to 
examine merger remedies and to adjust its policies accordingly. 
[Footnote 55] The Commission conducted retrospectives of the hospital 
industry to determine whether the harms alleged to arise from certain 
transactions came to fruition when the FTC did not obtain the relief it 
sought. The amount of effort and expertise that the Commission has 
devoted to evaluations of its actions has increased over time. 

Recently, the Commission has provided additional stimulus for putting 
evaluation into its decision-making processes. On June 18, 2008, the 
Commission formally announced the agency's latest self-evaluative 
initiative.[Footnote 56] A two-day roundtable entitled The FTC at 100: 
Into Our Second Century was held on July 29-30, 2008. This ongoing 
Commission self-assessment will focus on six general questions: (1) 
When we ask how well the Commission is carrying out its 
responsibilities, by what criteria should we assess its work? (2) What 
techniques should we use to measure the agency's success in meeting 
these normative criteria? (3) What resources - personnel, facilities, 
equipment - will the FTC need to perform its duties in the future? (4) 
What methods should the FTC use to select its strategy for exercising 
its powers? (5) How can the FTC strengthen its processes for 
implementing its programs? (6) How can the FTC better fulfill its 
duties by improving links with other governmental bodies and 
nongovernment organizations? This fall, the Commission plans to hold 
additional roundtable discussions within the United States and 
overseas.[Footnote 57] Among other ends, this initiative seeks to 
identify the best techniques for evaluation and ensure that the 
Commission incorporates them into its competition program. 

The Commission will consider GAO's recommendations along with other 
recommendations, including those resulting from the current self-
evaluations. The Commission anticipates that the ongoing self-
assessment will provide the framework for, among other things, 
evaluating past mergers in the petroleum industry and in other 
industries. 

By direction of the Commission.

Chairman: 

Enclosure: [See comment 4] 

The following are GAO's comments on the Federal Trade Commission's 
letter dated September 17, 2008. 

GAO Comments: 

1. The FTC Chairman commented that HHI concentration numbers are just 
the starting point for merger antitrust analysis and noted that FTC 
considers other competitive factors when examining a merger. We agree 
with these points and note that we calculated petroleum industry market 
HHIs to shed light on the general level of concentration in the 
petroleum industry, not to conduct an antitrust analysis regarding 
specific mergers or market regions or to provide a guide for conducting 
antitrust assessments. Such analysis would have involved looking at 
other competitive factors as noted in the Chairman's letter, such as 
barriers to entry or examining mergers between firms that operate in 
different, but related, segments of the industry, which was beyond the 
scope our work. Nonetheless, we believe that concentration analysis for 
broader regions, which may not exactly correspond to antitrust markets, 
is useful for assessing regional concentration in the same way that 
national-level indicators of unemployment or Gross Domestic Product 
growth are useful in examining the economic health of the country. Our 
report, therefore, indicates that there are regions that may have more 
or less potential for firms to exercise market power, and we did not 
draw further conclusions about the impact of market concentration on 
competition in any given region. In addition, FTC conducted 
concentration analysis with similar market definitions for such 
purposes in its 2004 report on competition in the petroleum industry. 
We made no changes to the report for this comment. 

2. The FTC Chairman commented that each merger involves analyzing a 
unique set of facts, such as examining barriers to entry or efficiency 
gains. We agree that each merger inevitably involves a unique set of 
circumstances and correspondingly unique considerations. We added 
language to the report to clarify this point. 

3. The FTC Chairman commented on the difficulties of delineating 
geographic antitrust markets and noted, in this regard, that we did not 
include a large number of suppliers that could affect the New York 
Harbor refining market. We recognize the difficulty of delineating 
markets and understand that the use of spot markets for evaluating 
market concentration in the refining subsegment includes a number of 
limitations, most notably that spot market regions do not necessarily 
correspond to geographic regions that could be used as antitrust 
markets. On the basis of our consultations with experts at OPIS, EIA, 
and the Chairman's own experts at FTC, and for the reasons highlighted 
in appendix II, we decided that spot market HHIs were appropriate for 
analysis of the general state of concentration in the refining 
industry. We also recognize that there are other factors, in addition 
to market concentration, that are important in evaluating the 
competitive conditions in a given market. In our reporting of spot 
market concentrations we presented other factors that were unique to 
each spot market, including--for example, in the New York market--the 
sizable shipments of gasoline into this market from foreign and Gulf 
Coast refineries. Since the draft report already noted these 
limitations, which were raised by the FTC Chairman, we made no change 
for this comment.

Footnotes: 

[1] A merger, as defined in this study, involves either the sale of all 
or part of the stock or assets of a company to another. FTC generally 
uses the term “merger” to refer to the purchase of all of the stock of 
one company by another company and uses the terms “asset acquisition” 
or “partial stock acquisition” to describe other types of transactions. 

[2] Antitrust enforcement agencies can also challenge completed mergers 
if they violate antitrust laws. 

[3] For an example of the need for internal control, see: GAO, 
Financial Audit: Restated Financial Statements—Agencies’ Management and 
Auditor Disclosures of Causes and Effects and Timely Communication to 
Users, [hyperlink, http://www.gao.gov/cgi-bin/getrpt?GAO-07-91] 
(Washington, D.C.: Oct. 5, 2006).

in the energy sector that provides financial and operational data for, 
as well as analyses of, more than 400 oil and gas companies.

Pipelines, The Liquid Pipeline Industry in the United States: Where 
It’s Been, Where It’s Going (2004).

[7] Clayton Antitrust Act of 1914, 15 U.S.C. §§ 12–27, 29 U.S.C. §§ 
52–53. 

[8] The threshold for transaction size was $50.0 million in 2000, but 
changes on the basis of the prior year’s Gross National Product. For 
2008, the threshold was $63.1 million. Because our review covered a 
range of years and the actual thresholds varied from year to year, we 
often refer to the 2000 baseline. 

[9] DOJ has responsibility for investigating mergers, joint ventures, 
and potentially anticompetitive conduct in the oil field services and 
equipment industry. Companies in this industry provide services to the 
petroleum exploration and production industry but do not produce 
petroleum themselves. Examples of oil field services include the 
manufacture and supply of oil rigs and oil rig drilling equipment, 
diving support for offshore rigs, and pipeline services. 

[10] HHI gives proportionally greater weight to firms with larger 
market shares. For example, if there are two firms that sell products 
in a market with market shares of 60 percent and 40 percent, 
respectively, the calculation of HHI would be 602+402 = 5,200. 

[11] The maximum value for HHI is 10,000, which occurs when a single 
market participant has 100 percent of the market share. 

[12] As we have previously mentioned, for the purpose of this report, 
“U.S. mergers” includes mergers that had a reported location in the 
United States or were diversified across multiple countries, but that 
we had reasonable evidence to believe included a United States 
location. We decided this definition coincided with mergers that would 
affect U.S. markets, and, hence, FTC could potentially review. FTC 
staff noted that many of these mergers might not have any competitive 
overlap and, therefore, would not pose antitrust concerns. 

[13] Unless otherwise noted, we use the term “this period” to refer to 
the January 2000 through May 2007 time frame throughout this section of 
the report. 

[14] Given that our analysis included mergers through May 2007, we only 
show the total number of mergers for 2006. 

[15] Despite the threshold for premerger notification under Hart-Scott-
Rodino, FTC staff said that they can still review mergers of any size 
to determine whether they violate antitrust laws. 

[16] While there is no universally agreed-upon definition of what is 
meant by conventional versus nonconventional oil, the International 
Energy Agency states that “conventional” sources are considered to be 
those that can be produced using today’s mainstream technologies, while 
“nonconventional” sources require more complex or more expensive 
technologies to extract, such as oil sands and oil shale. 

[17] Estimates of oil reserves are based on data from Oil and Gas 
Journal, as reported in GAO, Crude Oil: Uncertainty about Future Oil 
Supply Makes It Important to Develop a Strategy for Addressing a Peak 
and Decline in Oil Production, [hyperlink, http://www.gao.gov/cgi-
bin/getrpt?GAO-07-283] (Washington, D.C.: Feb. 28, 2007).

Companies, The James A. Baker III Institute for Public Policy (Rice 
University, November 2007). 

[19] Less information is provided on the rationale for mergers in the 
midstream segment, relative to the information provided for the 
upstream and downstream segments. This is due to a number of factors, 
including but not limited to the following: (1) less information was 
publicly available on the rationale for mergers in the midstream 
segment and (2) midstream operators were generally less available for 
interviews and comment. 

[20] These refining regions are based on historical groupings of U.S. 
refiners. FTC staff indicated that these regions would not always 
correspond to bulk gasoline supply markets, which would include the 
supply of gasoline that comes from outside refiners. See appendix II 
for a more detailed discussion of how we defined “spot markets” and the 
limitations of this approach. 

[21] Over the past 25 years, spare refinery capacity has been reduced, 
in part, because no new refineries have been built in the United States 
since the 1970s. Industry officials cited stringent environmental 
regulations and low expectations of profitability as the reason that 
they have not built any new refineries. In addition, refiners have been 
reluctant to invest the billions of dollars needed to build new 
facilities when faced with uncertain demand growth in the future. There 
has been, however, a steady expansion of existing refinery capacity 
since the 1970s. Despite these expansions, refineries often run at or 
near 90 percent capacity. 

[22] There are no reliable data sources for the size of these shipments 
by refinery or for the origins of imported fuel into the United States. 
EIA collects data on the basis of the name of the fuel shipper, which 
is often different than the name of the refining company in the country 
of origin. It was, therefore, not possible for us to accurately 
calculate HHIs with foreign refiners included. The 60 percent 
consumption rate is based on 2007 EIA data as of August 20, 2008. 

[23] This percentage is based on 2007 EIA data as of August 20, 2008. 

[24] This percentage is based on 2007 EIA data as of August 20, 2008.

14] (Washington, D.C.: Dec. 20, 2007). 

[26] These data reflect the increasing merger value thresholds for 
filings required under Hart-Scott-Rodino. 

[27] We define “retrospective review” to be a quantitative post merger 
analysis to determine the effects on price or competition, if any, 
resulting from a completed merger.

[37] A futures contract is a financial contract in which a buyer and 
seller agree to buy or sell a commodity, such as crude oil, in the 
future for a particular price. Almost all futures contracts change 
ownership without the actual physical delivery of the commodity. 

[38] FTC staff indicated that they obtain permission from private firms 
before using data reported to EIA for law enforcement purposes. 

[39] States can monitor petroleum markets through their state energy 
commissions or through their state attorneys general offices. 

[40] Angie A.Welborn and Aaron M. Flynn, Gasoline Price Increases: 
Federal and State Authority to Limit “Price Gouging,” CRS Report for 
Congress (May 18, 2006). 

[41] In support of our analysis of the upstream segment, we conducted 
one analysis of global petroleum industry mergers that exceeded $10 
million in value. 

[42] These calculations did not take into account a refinery’s ability 
to produce gasoline blends designed to meet specific regional air 
quality requirements, such as those in states like California. 

[43] Our capacity data used “barrels per stream day,” which reflects 
the number of barrels processed in a refinery on an average day when it 
is in operation. 

[44] In general, if a refinery did not have one of these three units, 
we did not assign it any gasoline production capacity. Refineries 
without one of these units most likely do not produce any gasoline 
(i.e., asphalt refineries). However, there are some older refineries 
that use hydrocrackers to produce gasoline, rather than the more common 
FCC. We worked with EIA to identify these and then used data from 
company publications to account for the gasoline production capacity of 
these refineries. We did not include capacities from the isomerization 
units or cokers because, according to our discussion with EIA 
officials, these units feed into reformers and FCCs, which we capture 
in our approach. 

[45] According to EIA, our capacity estimates are more relative than 
actual because we were not able to account for the light components 
(hydrocarbons with four to six carbon atoms) that make up a portion of 
blended gasoline depending on the fuel’s vapor pressure and octane 
requirements. Therefore, a refinery’s actual gasoline capacity will be 
slightly more than our estimates. However, the capacities of refineries 
relative to one another will not be significantly affected because we 
treated all of the refineries the same by not including the light 
components, and the estimates will be accurate for the purposes of 
calculating HHI. EIA agreed that our overall approach is better than 
using total operable, or operating, capacity to estimate refinery 
gasoline production. 

[46] Fuel “exchanges” are not included in the wholesale supply data. 
During an exchange, fuel is sold under a different brand than where it 
originated. Exchanges allow refiners to have retail locations where 
they do not have any refining presence. These volumes are recorded as 
being sold by the original producer. For example, if ConocoPhillips 
were to agree to sell fuel to Chevron dealers who rebrand the fuel as 
Chevron, the prime supply data would still list the fuel sale under the 
name ConocoPhillips. 

[47] A refinery’s ability to serve a spot market is based on its 
ability to supply fuel to the market in 7 to 10 days and to do so with 
a profit margin of less than 5 cents per gallon, according to one OPIS 
official. FTC staff told us that their market definitions for antitrust 
enforcement usually involve profit margins of 1 to 2 cents per gallon, 
and longer supply windows, usually 1 to 2 years. 

[48] We also removed from our calculations refineries in Kentucky, 
Montana, Nevada, and West Virginia that, according to the experts, only 
supplied their local regions. 

[49] In addition, some refineries in the Pacific Northwest can also 
produce gasoline that meets California specifications, and it is 
periodically shipped to either California market. We included these 
refineries in the California regions where appropriate. Also, we 
included a number of Mid-continent refineries in the Pacific Northwest 
region if they were also able to ship gasoline to that region. We also 
included some Texas refineries in the Mid-continent market if they had 
access to the Magellan pipeline. We made the above inclusions on the 
basis of comments from EIA and FTC. 

[50] Law enforcement involving both merger and non-merger cases is a 
key component of the FTC's program to maintain competition in the 
petroleum industry. The FTC carefully analyzes proposed mergers, 
reviewing all pertinent facets of the relevant petroleum markets, and 
challenges transactions that likely would substantially reduce 
competition or result in higher prices. Similarly, the FTC focuses on 
anticompetitive conduct and other activities involving pricing and 
competition in the petroleum industries. All told, in the past year, 
between 125 and 150 FTC staff members - attorneys, economists, 
paralegals, research analysts, and others - have worked on matters 
involving antitrust and pricing issues in the oil and natural gas 
sector. Most notably, in the past year, two transactions were 
abandoned - one after the Commission challenged the proposed 
acquisition in court, and the other during the Commission's 
investigation. See FTC. v. Equitable Resources, Inc., Dominion 
Resources, Inc. et al., Civ. Action No. 07-cv-490 (W.D. Pa.), vacated 
as moot (3d Cir. Feb. 5, 2008) (parties advised the FTC that they were 
abandoning the transaction), available at [hyperlink, 
http://www.ftc.gov/os/closings/staff/0810052marathonclosingletter_stepto
e.pdf]. The Commission last year sought unsuccessfully to block a 
merger involving New Mexico refining. Federal Trade Commission v. 
Foster et al., No. Civ. 07-352 JB/ACT (D.N.M. May 29, 2007), available 
at 2007 WL 1793441. The Commission also recently concluded an 
investigation into gasoline and diesel prices in the Pacific Northwest, 
and the agency continues its Gasoline and Diesel Price Monitoring 
Project (discussed in more detail below). The Commission fully expects 
to maintain its intensive antitrust scrutiny of the energy sector. 

[51] For this letter, we will use the term "merger" to include both 
stock and asset acquisitions, as GAO did in its Report.
