Equity [Abstract]
PREFERRED STOCK AND RELATED WARRANT	PREFERRED STOCK AND RELATED WARRANT On November 21, 2008, as part of the Capital Purchase Program established by the Treasury under the Emergency Economic Stabilization Act of 2008 (the EESA), the Company entered into a Purchase Agreement with Treasury pursuant to which the Company issued and sold to Treasury 124,000 shares of Series A Preferred Stock, having a liquidation preference of $1,000 per share ($124 million liquidation preference in the aggregate), and as more fully explained below, a ten-year warrant to purchase up to 243,998 shares (post reverse-split) of the Company’s common stock, par value $0.01 per share, at an initial exercise price of $76.23 per share (post reverse-split), for an aggregate purchase price of $18.6 million in cash. The warrant issued is immediately exercisable, in whole or in part, has a ten-year term and the number of shares is subject to certain customary anti-dilution and other adjustments. The warrant is not subject to any contractual restrictions on transfer. The Company has granted the warrant holder piggyback registration rights for the warrant and the common stock underlying the warrant and has agreed to take such other steps as may be reasonably requested to facilitate the transfer of the warrant and the common stock underlying the warrant. The holder of the warrant is not entitled to any common stockholder rights. The Treasury agreed not to exercise voting power with respect to any shares of common stock of the Company issued to it upon exercise of the warrant. On March 29, 2012, the Company's $124 million of Series A Preferred Stock was sold by the Treasury as part of its efforts to manage and recover its investments under the TARP. While the sale of these preferred shares to new owners did not result in any proceeds to the Company and did not change the Company's capital position or accounting for these securities, it did eliminate restrictions put in place by the Treasury on TARP recipients. The Treasury retained its related warrant to purchase up to $18.6 million in Banner common stock. Subsequent to March 29, 2012, the Company repurchased or redeemed all of its Series A Preferred Stock, realizing gains aggregating $2.5 million, which was partially offset by accelerated amortization of a portion of the initial discount recorded at the issuance of the Series A Preferred Stock. As a result, the accrual for the quarterly dividend was reduced by the retirement of these shares. As of December 31, 2012, all of the Series A Preferred Stock had been retired.
