Business Acquisition, Pro Forma Information [Table Text Block] | The following table presents certain unaudited pro forma information for illustrative purposes only, for the years ended December 31, 2013 and 2012 as if West Coast had been acquired on January 1, 2012. The unaudited estimated pro forma information combines the historical results of West Coast with the Company's consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred on January 1, 2012. In particular, no adjustments have been made to eliminate the impact of other-than-temporary impairment losses and losses recognized on the sale of securities that may not have been necessary had the investments securities been recorded at fair value as of January 1, 2012. The unaudited pro forma information does not consider any changes to the provision for credit losses resulting from recording loan assets at fair value. Additionally, Columbia expects to achieve further operating cost savings and other business synergies, including revenue growth, as a result of the acquisition which are not reflected in the pro forma amounts that follow. As a result, actual amounts will differ from the unaudited pro forma information presented.
