Earning asset bals exceeded our est. given less dep attrition, and the NIM came in 3bp above as mgmt shifted cash into higher-yielding secs.

4Q Miss Due to Credit; Pressures to Persist

Worse-than-expected credit results drove the 4Q miss ZION reported EPS of ($0.62), missing UBSe & cons. estimates of ($0.45) &($0.36), resp. NII came in higher, but credit costs offset. We increase ’11E (to aloss of $0.40 from a loss of $1.00) & ‘12E (to $0.80 from $0.75) due to faster LLRrelease and to acc’t for the NII beat.

Credit recovery likely, but pace to disappoint Credit losses were 5% higher than our estimate. Worse-than-expected term CRE & const. trends offset better results within resi RE. Const recovery will likelyimprove losses, but we believe cont’d duress w/in term CRE & resi RE will keeplevels elevated. We are lowering our ’11 (to 160bp from 175bp) & ’12 loss est. (to80bp from 85bp ) to account for this qtr’s resi RE beat. Fortunately, we believeZION still has meaningful credit leverage ahead (LLR ratio = 3.9%).

Lending revs to trend down in the near-term Lending revs trended flat and were 2% above our forecast. Earning asset balsexceeded our est. given less dep attrition, and the NIM came in 3bp above as mgmtshifted cash into higher-yielding secs. Cont’d mix-shift will likely enhance the core NIM, but it will unlikely offset the decline in loans. As such, we are forecasting a5% decline in NII for ’11.

Maintain Sell Rating; expectations remain elevated ZION trades at 29x our ’12E vs. our 13x target multiple. Our three-prong valuation methodology (P/E, P/TBV, and DCF) drives our price target to $17 from $16.

Zions Bancorporation

Zions Bancorporation is a Salt Lake City-based bank holding company with a balance sheet in excess of $50 billion. Zions operates in Utah, Arizona, Nevada, Texas, California, New Mexico, Colorado, Oregon, and Washington. The company's outstanding loans include commercial real estate (39%), C&I (24%), construction (18%), and residential real estate (15%). In early 2009, Zions issued ~$255 million as part of the US Treasury's TARP program.

Statement of Risk

Upside risks to our Sell rating include: 1) a more robust economic recovery, which would translate into lower losses in commercial and CRE loans; 2) Fed tightening that is either or both greater and faster than anticipated, driving lending margins upward; and 3) more aggressive reserve drawdown, enhancing credit leverage to normalized EPS.

KEY DEFINITIONS Forecast Stock Return (FSR) is defined as expected percentage price appreciation plus gross dividend yield over the next 12 months. Market Return Assumption (MRA) is defined as the one-year local market interest rate plus 5% (a proxy for, and not a forecast of, the equity risk premium). Under Review (UR) Stocks may be flagged as UR by the analyst, indicating that the stock's price target and/or rating are subject to possible change in the near term, usually in response to an event that may affect the investment case or valuation. Short-Term Ratings reflect the expected near-term (up to three months) performance of the stock and do not reflect any change in the fundamental view or investment case. Equity Price Targets have an investment horizon of 12 months. EXCEPTIONS AND SPECIAL CASES UK and European Investment Fund ratings and definitions are: Buy: Positive on factors such as structure, management, performance record, discount; Neutral: Neutral on factors such as structure, management, performance record, discount; Sell: Negative on factors such as structure, management, performance record, discount. Core Banding Exceptions (CBE): Exceptions to the standard +/-6% bands may be granted by the Investment Review Committee (IRC). Factors considered by the IRC include the stock's volatility and the credit spread of the respective company's debt. As a result, stocks deemed to be very high or low risk may be subject to higher or lower bands as they relate to the rating. When such exceptions apply, they will be identified in the Company Disclosures table in the relevant research piece. Research analysts contributing to this report who are employed by any non-US affiliate of UBS Securities LLC are not registered/qualified as research analysts with the NASD and NYSE and therefore are not subject to the restrictions contained in the NASD and NYSE rules on communications with a subject company, public appearances, and trading securities held by a research analyst account.

Source: UBS; as of 24 Jan 2011 Note: On August 4, 2007 UBS revised its rating system. (See 'UBS Investment Research: Global Equity Rating Definitions' table for details). From September 9, 2006 through August 3, 2007 the UBS ratings and their definitions were: Buy 1 = FSR is > 6% above the MRA, higher degree of predictability; Buy 2 = FSR is > 6% above the MRA, lower degree of predictability; Neutral 1 = FSR is between -6% and 6% of the MRA, higher degree of predictability; Neutral 2 = FSR is between -6% and 6% of the MRA, lower degree of predictability; Reduce 1 = FSR is > 6% below the MRA, higher degree of predictability; Reduce 2 = FSR is > 6% below the MRA, lower degree of predictability. The predictability level indicates an analyst's conviction in the FSR. A predictability level of '1' means that the analyst's estimate of FSR is in the middle of a narrower, or smaller, range of possibilities. A predictability level of '2' means that the analyst's estimate of FSR is in the middle of a broader, or larger, range of possibilities. From October 13, 2003 through September 8, 2006 the percentage band criteria used in the rating system was 10%.
