Warren Buffett tells CNBC's Becky Quick that Berkshire Hathaway has talked to five big financial firms about buying their tax credits.
Buffett says he can't name any names due to confidentiality agreements, but notes that Berkshire has been buying tax credits since 1990 and will continue to do so in the future.
This morning's Wall Street Journal reports Berkshire has joined with Goldman Sachs in an effort to buy $3 billion in tax credits from Fannie Mae , the big government owned mortgage company.
