Teekay Tankers said two of the main proxy voting firms have given their okay on a shareholder vote that is needed to consummate the merger with Tanker Investments (TIL).

Institutional Shareholder Services and Glass, Lewis & Co recommend that shareholders in the New York-listed firm vote for the proposed charter amendment.

The charter amendment faced scrutiny after the second largest shareholder in Teekay, Huber Capital Management, balked at the original terms of the TIL deal.
