Ambac Financial

( ABK) was one of several stocks poised to move on above-average volume Friday after the embattled bond insurer announced debt-for-equity exchange transactions.

said late Thursday it will issue approximately 5.03 million share of common stock in exchange for a total of $8.5 million in debt to bondholders. Following the transactions, there will be more 293.42 million shares of Ambac common stock outstanding.

as liquidity may run out before the second quarter of 2011. That news dropped Ambac shares to a 52-week low of 51 cents.

Ambac shares were rising by 4 cents, or 5.1%, to 82 cents in the premarket session. The three-month average daily share volume for Ambac is 57.96 million, according to Yahoo! Finance.
