One of the nation's leading credit rating agencies has assigned an "above average," or A1, rating to the up-to-$38 million in certificates of participation Colorado Springs plans to issue to fund U.S. Olympic Committee improvements.

The rating by Moody's Investors Service reflects the creditworthiness of such types of municipal borrowing, according to an explanation on Moody's Web site. The A1 rating falls short of an Aa rating, which means "very strong" creditworthiness, or Aaa, which is Moody's "strongest" rating.
