PrivateBancorp has moved up the date for its shareholders to vote on a deal that could see Toronto-based Canadian Imperial Bank of Commerce (CIBC) buy the Chicago-based lender.

The U.S. bank announced on Monday that its special meeting to vote on the acquisition is now expected to be held on or about May 4.

Previously, a shareholder vote scheduled for December 2016 was postponed after shares of PrivateBancorp rose above the value implied in the proposed takeover deal, which was announced in June of last year.

At the time, PrivateBancorp said its shareholders needed more time to consider the transaction.

The acquisition of PrivateBancorp would allow CIBC to expand its business in the U.S. amid slowing loan growth at home.

CIBC is Canada’s fifth largest bank by market capitalization.
