Bank of America is giving up a months-long fight with regulators, and plans to turn over documents revealing legal advice it received on its purchase of Merrill Lynch.

In a turnabout, the bank will waive attorney-client privilege that kept it from telling regulators about recommendations it received from outside attorneys over whether to disclose details to shareholders about Merrill’s mounting troubles.

Yesterday, BofA spokesman Larry DiRita said, “Given the pressure in multiple inquiries to provide additional insight, we’ve decided to waive it in this matter to get the issue behind us.”

“We’ve got nothing to hide and are certain we did everything proper in the context of the Merrill acquisition,” he added.
