Subject: File No. S7-09-00 Date: 03/24/2000 1:36 PM Dear Mr. Jonathan G. Katz: Ref. S7-09-00 I am the president of the investment advisory firm named Dynamic Capital Management. In my practice I have solved the mathematical problems associated with tax efficiency, or rather tax optimization. We have received notification of the allowance of a patent on our about to be release product called DynamicTaxOptimizer. It involves inputs of a set of facts and alternate price performance expectations. In it we are able to calculate for investors on a lot-by-lot basis at what price it makes sense to sell a stock, pay the tax, and reinvest for higher after tax wealth. We expect it to become a standard in the industry because it represents a higher value goal of maximizing wealth instead of minimizing taxes. The reason I mention this is that one of the essential elements of the discipline is to discriminate not only on the basis of each lot by purchase date, and cost basis, but also of tax rates. Lower tax rated individuals can justify higher turnover than higher ones. Lower cost basis lots, or those subject to higher tax rates, need higher rates of returns to justify a sale. This because the additional tax burden suffered by the selling and reinvesting, as opposed to the continued holding of a lot, needs to be offset by the superior performance of a substitute investment as compared with holding a position. The practical consequence is that given an assumed reinvestment rate, only higher sale prices warrant a sale for such lower cost basis, or higher tax burdened lots. Therefore, since this will also work in commingled environments, mutual funds will eventually want to offer different funds targeted at different tax rated individuals in order to optimize after tax results. Using the same turnover for all tax rated individuals will either result in lost opportunities for lower tax rated individuals, or too high taxes for higher ones. Therefore a requirement that the highest tax rates should be assumed for all reporting of mutual fund performance may substitute for what may possibly be more accurate results associated with a properly executed tax optimization discipline. Or it may inadvertently disaffect an otherwise more sophisticated and optimal strategy that must discriminate by purchase date, cost basis, and tax rates, in order to be fully effective. We believe that the only way for accurate after tax results to be represented is either to have an investors tax rates inputted into a system before performance numbers are presented, or that a table, or set of tables, be presented whereby investors could match their respective short and long term tax rates and identify their appropriate respective performance. The importance and application of all this in the separate account arena is no less. Our website will be available to the mass market by May, and institutionally in the months that follow. We believe it represents what is the first fundamental, and we think best, solution to date, for this complex subject. If you would like some material on the efficacy of DynamicTaxOptimizer, or would like a demonstration of it's logic and power, I would be happy to offer it to you. The math is compelling, and we are receiving a substantial reception from the investment community, even prior to market availability. We also anticipate the patent issuance by June, having satisfied all federal requirements. Our goal here is to perhaps alert you to the potential regulatory impedance that a flat based measurement benchmark might generate, at what could otherwise be the forefront of significant market sophistication and customer service enhancement and disclosure capability. Across perhaps a variety of technology supported products. We applaud your move to improve the customer protection environment. We would be delighted to work with you to that end. I hope this has been helpful, and would look forward to brief you further should you desire. Thank you for your time. Respectfully; David Gottstein President DynamicTaxOptimizer LLC
