Clear Channel buyout in trouble

The $20 billion leveraged buyout of U.S. radio operator Clear Channel Communications Inc was in jeopardy on Tuesday, with banks increasingly reluctant to provide financing, a source familiar with the situation said.

The banks appear unwilling to account for any losses on the loans they agreed to make for the deal, the source said. But the final resolution is unclear, with the private equity buyers still wanting to do a deal, the source added.
