April 5 (Reuters) - Proxy advisers Glass Lewis and

Institutional Shareholder Services (ISS) on Friday both urged

Bank of America ( BAC ) to split the CEO and chairman roles held

by Brian Moynihan.

"Appointment of a chair of the board who is independent of

management, i.e. not also serving as CEO, is nearly always

preferable to having a single individual lead both the board and

the executive team," Glass Lewis said in a note.

The second-largest U.S. bank appointed Moynihan as chief

executive in 2009, followed by his appointment as chair in 2014.

Earlier this week, the advisers also urged Goldman Sachs ( GS )

to split its CEO and chair roles, which are held by David

Solomon, and urged a further break with management by calling on

shareholders to reject the bank's executive pay plans.

After the 2008 financial crisis, investors seeking to

improve risk oversight mounted efforts to separate the chair and

CEO roles at Goldman and other Wall Street giants like JPMorgan

Chase ( JPM ).

Banks often fended these off by making other changes, such

as giving new powers to a lead independent director, which

Goldman also did in 2013.
