Banco Bilbao Vizcaya Argentaria, S.A. (NYSE: BBV) (MAD: BBVA) and Compass Bancshares, Inc. (NASDAQ: CBSS) today preliminarily announced the transaction consideration to be received by Compass stockholders in BBVA’s pending acquisition of Compass.

Based on election results and applying the proration procedures described in the transaction agreement, holders of Compass stock upon the closing of the transaction are preliminarily expected to receive the following transaction consideration:
