SECTION 9. CREDIT RATE

For each issue of clean renewable energy bonds, a separate credit rate will apply to each of the level annual repayments of principal of the issue (each, a “principal maturity”). The credit rate for a principal maturity of an issue of clean renewable energy bonds is the applicable clean renewable energy bond credit rate published each business day by the Bureau of Public Debt on its Internet site for State and Local Government Series securities at: http://www.publicdebt.treas.gov . The applicable clean renewable energy bond credit rate shall be applied to a principal maturity of an issue of clean renewable energy bonds on the day the issue is sold. The credit rates will be determined by the Treasury Department based on its estimate of the yield on outstanding AA rated corporate bonds of a similar maturity for the business day immediately prior to the date on which the issue is sold.
