Financial paper that is insured by the FDIC's Temporary Liquidity Guarantee Program is not excluded from relevant indexes, nor is any financial, nonfinancial, or asset-backed commercial paper that may be directly or indirectly affected by one or more of the Federal Reserve's liquidity facilities. Thus the rates published after September 19, 2008, likely reflect the direct or indirect effects of the new temporary programs and, accordingly, likely are not comparable for some purposes to rates published prior to that period.

Through November 4, the documentation on the "About" page of this release indicated that paper issued under "credit-enhanced programs" was excluded from the samples of issues used to calculate reported rates. This wording was intended to convey that asset-backed commercial paper was excluded from the calculation of financial rates. Indeed, consistent with that intent, the Federal Reserve has, since 2006, published a separate rate series for asset-backed commercial paper. To avoid confusion, the reference to "credit-enhanced programs" will be dropped.

On May 29, 2008, the Federal Reserve Board will release revisions to the values of seasonally adjusted and not seasonally adjusted commercial paper outstanding levels based on updated issuer information. The revisions affect weekly and monthly outstanding data from January 2001 to May 2008 as well as year-end values and maturity distribution of outstanding commercial paper.

The Federal Reserve Board will be closed on Monday, December 24. Commercial paper data will not be updated on that day. The data for Friday, December 21 and Monday, December 24 will be available on Wednesday, December 26.

The commercial paper rates and volume statistics for November 15, which are derived from source data provided by the Depository Trust & Clearing Corporation (DTCC), have been reissued to reflect corrected source data.

On June 18, 2007, the Federal Reserve Board stopped using Fitch Investors Service as a credit rating source. Classification as AA or A2/P2 for rate calculations and classification as Tier-1 or Tier-2 for outstanding calculations are done using Moody's Investors Service and Standard & Poor's.
