April 3 (Reuters) - Top proxy adviser Institutional Shareholder Services (ISS) on Wednesday recommended investors support a call for an independent board chair at Goldman Sachs.

"Shareholders would benefit from more independent oversight in the form of an independent chair," ISS wrote in a report sent by a representative, ahead of the bank's annual shareholder meeting on April 24.

ISS also recommended votes 'for' all the bank's director nominees and said that "cautionary support" was warranted for its executive pay although the pay program relies too much on discretion. (Reporting by Ross Kerber)
