NEW YORK (Bloomberg) — Bermuda-based Assured Guaranty Ltd.'s AAA bond insurer credit rating was affirmed by Moody's Investors Service on the heels of the company getting an investment of as much as $1 billion from Wilbur Ross.

The outlook is stable, New York-based Moody's said in a statement yesterday. The ratings affirmation reflects "Moody's assessment of the capital adequacy and strengthened market position of" Assured Guaranty and its units, Moody's said.
