ITEM 8.01. OTHER EVENTS

Zions Bancorporation (“Zions”) previously disclosed its expectation that increased prepayments experienced in its collateralized debt obligation (“CDO”) portfolio during the fourth quarter would lead to higher other-than-temporary impairment (“OTTI”) charges as a result of the use of higher constant prepayment rate (CPR) speeds in its valuation models for these securities.

Additionally, following discussions with federal banking regulators, which are ongoing, Zions is reviewing assumptions in its valuation models for certain bank holding company trust preferred securities that underlie certain of Zions’ CDO securities. The trust preferred securities in question are those that are currently deferring distributions and nearing the end of their deferral periods. Zions currently expects that, in combination with the effect of the higher CPR speeds, this could lead to the incurrence of OTTI in Zions’ CDO portfolio in the fourth quarter in an amount that Zions anticipates would not exceed $100 million.

The foregoing consists of forward-looking statements which are expressly subject to the safe harbor provided by the Private Securities Litigation Reform Act of 1995. There are many factors that could cause actual results to differ, perhaps materially, from Zions’ expectations set forth above, including the fact that Zions has not completed its review of these matters. For other important factors that could cause future events to differ from Zions’ current expectations, please see Zions’ most recent Annual Report on Form 10-K for the year ended December 31, 2011 and its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2012, June 30, 2012 and September 30, 2012, including without limitation under the captions “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures About Market Risk” and in other documents that Zions may file with the SEC.
