Western Alliance Bancorporation and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

Note 1. Nature of Business and Summary of Significant Accounting Policies

(Dollars in thousands, except per share amounts)

Nature of business

Western Alliance Bancorporation is a bank holding company providing a full range of banking services to commercial and consumer clientele through its wholly owned subsidiaries: Bank of Nevada and First Independent Bank of Nevada, operating in Nevada; Alliance Bank of Arizona, operating in Arizona; Torrey Pines Bank and Alta Alliance Bank, operating in California; Miller/Russell & Associates, Inc., operating in Nevada, Arizona and Southern California; Premier Trust, Inc., operating in Nevada and Arizona and Shine Investment Advisory Services, Inc., operating in Colorado. These entities are collectively referred to herein as the Company. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America and general industry practices.

Use of estimates in the preparation of financial statements

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes in the near term relate to the determination of the allowance for loan losses, fair value of collateralized debt obligations (CDOs), classification of impaired securities as other-than-temporary and impairment of goodwill and other intangible assets.

Principles of consolidation

With the exception of certain trust subsidiaries which do not meet the criteria for consolidation pursuant to Financial Accounting Standards Board (FASB) Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities, the consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Bank of Nevada and its subsidiary BW Real Estate, Inc., Alliance Bank of Arizona, Torrey Pines Bank, Alta Alliance Bank, First Independent Bank of Nevada (collectively referred to herein as the Banks), Miller/Russell & Associates, Inc., Premier Trust, Inc., and Shine Investment Advisory Services, Inc. All significant intercompany balances and transactions have been eliminated in consolidation.

Interim financial information

The accompanying unaudited consolidated financial statements as of September 30, 2008 and 2007 have been prepared in condensed format, and therefore do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. These statements have been prepared on a basis that is substantially consistent with the accounting principles applied to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2007.

The information furnished in these interim statements reflects all adjustments which are, in the opinion of management, necessary for a fair statement of the results for each respective period presented. Such

7

Western Alliance Bancorporation and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

adjustments are of a normal recurring nature. The results of operations in the interim statements are not necessarily indicative of the results that may be expected for any other quarter or for the full year. The interim financial information should be read in conjunction with the Company’s annual audited financial statements.

Repurchase program

For the nine months ended September 30, 2008, the Company repurchased 20,000 shares of common stock on the open market with a weighted average price of $17.75 per share. The Company has the remaining authority to repurchase shares with an aggregate purchase price of $30.6 million under a share repurchase program authorized by the Board of Directors through December 31, 2008. All repurchased shares are retired as soon as is practicable after settlement.

Recent Accounting Pronouncements

On October 10, 2008, the FASB issued Staff Position (FSP) No. 157-3, which clarifies the application of Statement of Financial Accounting Standards (SFAS) No.157,Fair Value Measurements (SFAS 157), in an inactive market and illustrates how an entity would determine fair value when the market for a financial asset is not active. The FSP states that an entity should not automatically conclude that a particular transaction price is determinative of fair value. In a dislocated market, judgment is required to evaluate whether individual transactions are forced liquidations or distressed sales. When relevant observable market information is not available, a valuation approach that incorporates management’s judgments about the assumptions that market participants would use in pricing the asset in a current sale transaction would be acceptable. The FSP also indicates that quotes from brokers or pricing services may be relevant inputs when measuring fair value, but are not necessarily determinative in the absence of an active market for the asset. In weighing a broker quote as an input to a fair value measurement, an entity should place less reliance on quotes that do not reflect the result of market transactions. Further, the nature of the quote (for example, whether the quote is an indicative price or a binding offer) should be considered when weighing the available evidence. The FSP is effective immediately and applies to prior periods for which financial statements have not been issued, including interim or annual periods ending on or before September 30, 2008. Accordingly, the Company adopted the FSP prospectively, beginning July 1, 2008.

On October 14, 2008, the SEC’s Office of the Chief Accountant (OCA), clarified its views on the application of other-than-temporary impairment guidance in SFAS No. 115, to certain perpetual preferred securities. The OCA stated that it would not object to a registrant applying an other-than-temporary impairment model to investments in perpetual preferred securities that possess significant debt-like characteristics that is similar to the impairment model applied to debt securities, provided there has been no evidence of deterioration in credit of the issuer. An entity is permitted to apply the OCA’s views in its financial statements included in filings subsequent to the date of the letter. At September 30, 2008, based on the OCA guidance, the Company recorded no other-than-temporary impairment for investments in investment-grade perpetual preferred securities that had no evidence of credit deterioration and that the Company has the intent and ability to hold to recovery.

In September 2007, the FASB ratified the consensus of the Emerging Issues Task Force (EITF) Issue No. 06-4,Accounting for Deferred Compensation and Postretirement Benefit Aspects of Endorsement Split-Dollar Life Insurance Arrangement(EITF 06-4). EITF 06-4 applies to endorsement split dollar life insurance policies that provide a benefit to an employee that extends to postretirement periods and

8

Western Alliance Bancorporation and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

requires an employer to recognize a liability for future benefits over the service period based on the substantive agreement with the employee. EITF 06-4 is effective for fiscal years beginning after December 15, 2007, with early adoption permitted. The adoption of EITF 06-4 resulted in a cumulative effect adjustment charge of $0.2 million, effective January 1, 2008.

In December 2007, the FASB issued SFAS No. 141R, Business Combinations (SFAS 141R), and SFAS No. 160,Non-controlling Interests in Consolidated Financial Statements, an amendment of ARB No. 51 (SFAS 160). These new standards significantly change the accounting for and reporting of business combination transactions and non-controlling interests (previously referred to as minority interests) in consolidated financial statements. These statements are effective for the Company beginning on January 1, 2009. The Company does not expect SFAS 141R and SFAS 160 to have a material impact on the financial statements. These standards will change the Company’s accounting treatment for business combinations on a prospective basis.

In June 2008, the FASB issued FASB Staff Position No. EITF 03-6-1,Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities(FSP No. EITF 03-6-1). FSP No. EITF 03-6-1 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in the earnings allocation incomputing earnings per share, or EPS, under the two-class method described in paragraphs 60 and 61 of FASB Statement No. 128,Earnings per Share(SFAS 128). The guidance in this FSP applies to the calculation of EPS under SFAS 128 for share-based payment awards with rights to dividends or dividend equivalents. FSP No. EITF 03-6-1 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those years. All prior-period EPS data presented should be adjusted retrospectively to conform with the provisions of this FSP. Early application is not permitted. The implementation of this standard will not have a material impact on our consolidated financial position or results of operations.

Derivative Financial Instruments

All derivatives are recognized on the balance sheet at their fair value, with changes in fair value reported in current-period earnings. These instruments consist primarily of interest rate swaps.

Note 2. Fair Value Accounting

SFAS 157 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under SFAS 157 are described below:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 — Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market;

Level 3 — Valuation is generated from model-based techniques where all significant assumptions are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect our own

Western Alliance Bancorporation and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models and similar techniques.

For the three and nine months ended September 30, 2008, gains and losses from fair value changes included in the Consolidated Statement of Income were as follows (in thousands):

The difference between the aggregate fair value of $46.7 million and the aggregate unpaid principal balance of $66.5 million of junior subordinated debt was $19.8 million at September 30, 2008.

The difference between the aggregate fair value of $30.7 million and the aggregate unpaid principal balance of $30.0 million of fixed-rate term borrowings measured at fair value was $0.7 million at September 30, 2008.

Interest income on securities measured at fair value is accounted for similarly to those classified as available-for-sale and held-to-maturity. As of January 1, 2007, a discount or premium was calculated for each security based upon the difference between the par value and the fair value at that date. These premiums and discounts are recognized in interest income over the term of the securities. For mortgage-backed securities, estimates of prepayments are considered in the constant yield calculations. Interest expense on junior subordinated debt is also determined under a constant yield calculation.

Fair value on a recurring basis

The Company measures certain assets and liabilities at fair value on a recurring basis, including securities available-for-sale, securities measured at market value and junior subordinated debt. The fair value of these assets and liabilities were determined using the following inputs at September 30, 2008 (in thousands):

The value of the Company’s fixed-rate term borrowings and junior subordinated debt (level 3) are estimated by projecting the expected cash flows and discounting those cash flows at a rate reflective of the current market environment. For the junior subordinated debt, the Company factored in adjustments to the discount rate used in the cash flow projection for nonperformance risk and uncertainty in the model. The factors used in the estimation of value incorporate the Company’s own best estimates of assumptions that market participants would use in pricing the instruments or valuations that require significant judgment or estimation.

Fair value on a nonrecurring basis

Certain assets are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following table presents such assets carried on the balance sheet by caption and by level within the SFAS 157 hierarchy as of September 30, 2008 (in thousands):

The specific reserves for collateral dependent impaired loans are based on the fair value of the collateral less estimated costs to sell. The fair value of collateral was determined based on appraisals. In some cases, adjustments were made to the appraised values due to various factors including age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in the collateral. When significant adjustments were based on unobservable inputs, such as when a current appraised value is not available or management determines the fair value of the collateral is further impaired below appraised value and there is no observable market price, the resulting fair value measurement has been categorized as a Level 3 measurement. These Level 3 impaired loans had an aggregate carrying amount of $43.9 million and specific reserves in the allowance for loan losses of $9.6 million as of September 30, 2008.

In accordance with SFAS No. 142, Goodwill and Other Intangible Assets, goodwill was written down to its implied fair value of $138.6 million by a charge to earnings of $79.2 million at September 30, 2008. The key inputs used to determine the implied fair value of the Company and the corresponding amount of the impairment included the quoted market price of our common stock, market prices of common stocks of other banking organizations, common stock trading multiples, discounted cash flows, and inputs from comparable transactions. The Company attempted to maximize the use of observable (level 2) inputs. However, due to the adjustment for $79.2 million, which is based on the Company’s assumptions, the resulting, fair value measurement was determined to be level 3.

Note 3. Earnings Per Share

Diluted earnings per share are based on the weighted average outstanding common shares during each period, including common stock equivalents. Basic earnings per share are based on the weighted average outstanding common shares during the period.

Basic and diluted earnings per share, based on the weighted average outstanding shares, are summarized as follows:

Notes to Unaudited Consolidated Financial Statements

As of May 31, 2008, the Company transferred its trust preferred CDO portfolio from available-for-sale to held-to-maturity. The par value and fair value of these securities at the date of transfer were $121.4 million and $85.7 million, respectively. The unrealized losses of $35.7 million on the securities transferred to held-to-maturity remain included in other comprehensive loss and continue to be subject to the other-than-temporary impairment consideration rules of SFAS 115.

Net unrealized losses, net of taxes, increased $23.3 million for the nine months ended September 30, 2008 to $52.1 million from $28.7 million at December 31, 2007. The increase in unrealized losses is generally due to widening interest spreads which began in the third quarter of 2007. During March 2008 and thereafter, the near insolvency of Bear Stearns and other financial businesses, followed by the collapse of several major financial institutions in the third quarter of 2008 caused the debt of almost all financial companies to decline in value. This compounded the lack of liquidity for such securities that existed since late 2007. The Company is actively monitoring these portfolios for declines in fair value that are considered other-than-temporary. These combined unrealized losses were not considered as other-than-temporary as of September 30, 2008.

The Company conducts an other-than-temporary impairment analysis on a quarterly basis. The initial indication of other-than-temporary impairment for both debt and equity securities is a decline in the market value below the amount recorded for an investment, and the severity and duration of the decline. In determining whether an impairment is other than temporary, the Company considers the length of time and the extent to which the market value has been below cost, recent events specific to the issuer, including investment downgrades by rating agencies and economic conditions of its industry, and the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery. For marketable equity securities, the Company also considers the issuer’s financial condition, capital strength, and near-term prospects. For debt securities and for perpetual preferred securities that are treated as debt securities for the purpose of other-than-temporary analysis, the Company also considers the cause of the price decline (general level of interest rates and industry- and issuer-specific factors), the issuer’s financial condition, near-term prospects and current ability to make future payments in a timely manner, the issuer’s ability to service debt, and any change in agencies’ ratings at evaluation date from acquisition date and any likely imminent action. For perpetual preferred securities with a fair value below cost that is not attributable to the credit deterioration of the issuer, such as a decline in cash flows from the security or a downgrade in the security’s rating below investment grade, the Company may avoid recognizing an other-than-temporary impairment charge by asserting that it has the intent and ability to continue holding the securities for a sufficient period to allow for an anticipated recovery in market value. This assessment may include the intent and ability to hold the securities indefinitely.

At September 30, 2008, the Company was holding perpetual preferred stock of six issuers with an aggregate fair value of $45.4 million and an aggregate unrealized loss of $46.1 million. These securities are classified as available for sale. All of these securities remain investment grade (i.e. are rated BBB or higher) and continue to pay dividends. Since there has been no evidence of deterioration in the credit of the issuers, the Company is analyzing these securities using an impairment model similar to a debt security. Since the Company has the intent and ability to hold these securities indefinitely until they recover, the declines in fair value have been deemed to be temporary.

Gross unrealized losses at September 30, 2008 are primarily caused by interest rate changes, credit spread widening and reduced liquidity in applicable markets. The Company has reviewed securities on which there is an unrealized loss in accordance with its accounting policy for other-than-temporary impairment described above and recorded impairment charges totaling $38.0 million for the nine months ended September 30, 2008. This includes a $19.8 million impairment charge related to unrealized losses in the Company’s CDO portfolio, $15.2 million related to impairment losses in the Company’s adjustable rate preferred stock portfolio (ARPS) and $3.1 million related to an auction-rate leveraged security that was discussed in the Company’s Form 10-K for the year ended December 31, 2007.

The Company does not consider any other securities to be other-than-temporarily impaired as of September 30, 2008. However, without recovery in the near term such that liquidity returns to the

15

applicable markets and spreads return to levels that reflect underlying credit characteristics, additional other-than-temporary impairments may occur in future periods. At September 30, 2008, the Company had the ability and intent to hold all securities with significant unrealized losses in the available-for-sale portfolio.

Note 6. Goodwill

Goodwill arises from purchase business combinations. Goodwill and other intangible assets deemed to have indefinite lives generated from purchase business combinations are not subject to amortization and are instead tested for impairment no less than annually.

The majority of the Company’s goodwill has been assigned to the Nevada segment. The Nevada operating segment has two reporting units: the Bank of Nevada reporting unit and the First Independent Capital of Nevada reporting unit.

As a result of the current market volatility and changes in the financial services market environment, the Company determined it was necessary to test whether and to what extent the Company’s goodwill asset was impaired. The analysis performed compared the implied fair value of each reporting unit to the carrying amount of goodwill on the Company’s balance sheet. If the carrying amount of the goodwill exceeds the implied fair value of that reporting unit’s goodwill, an impairment loss must be recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as goodwill recognized in a business combination is determined. That is, the estimated fair value of the Company is allocated to all of the Company’s individual assets and liabilities, including any unrecognized identifiable intangible assets, as if the Company had been acquired in a business combination and the estimated fair value of the Company is the price paid to acquire it. The allocation process is performed only for purposes of determining the amount of goodwill impairment, as no assets or liabilities are written up or down, nor are any additional unrecognized identifiable intangible assets recorded as a part of this process.

After this analysis, it was determined the implied fair value of the goodwill assigned to the First Independent reporting unit was less than the carrying value on the Company’s balance sheet, and the Company reduced the carrying value of goodwill related to the First Independent Capital of Nevada (FICN) reporting unit by $79.2 million, through an impairment charge to earnings. Such charge had no effect on the Company’s cash balances or liquidity. In addition, because goodwill is not included in the calculation of regulatory capital, the Company’s regulatory ratios were not affected by this non-cash expense. No assurance can be given that goodwill will not be further impaired in future periods.

The Company also evaluated the goodwill of the Bank of Nevada reporting unit. The methodology used to evaluate the goodwill of the Bank of Nevada reporting unit was consistent with the method described above for the FIBN reporting unit. As a result of the analysis, it was determined that the fair value of the Bank of Nevada reporting unit exceeded the carrying value and therefore, there is no impairment of the goodwill assigned to the Bank of Nevada reporting unit.

The following table presents the changes in goodwill for the quarter ended September 30, 2008 (in thousands):

Deferred tax assets and liabilities are included in the financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred taxes assets and liabilities are adjusted through the provision for income taxes. For the nine months ended September 30, 2008, the net deferred tax assets increased $29.1 million to $55.0 million. This increase was primarily the result of a $13.8 million increase in deferred tax assets related to unrealized securities losses and a $13.7 million increase in deferred tax assets related to other-than-temporary impairment charges on the securities portfolio for the nine months ended September 30, 2008.

Note 9. Contingencies

In the normal course of business, the Company is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the consolidated financial statements.

Note 11. Segment Information

SFAS No. 131,Disclosures about Segments of an Enterprise and Related Information(SFAS 131), provides for the identification of reportable segments on the basis of discreet business units and their financial information to the extent such units are reviewed by an entity’s chief operating decision maker (which can be an individual or group of management persons).

The Company adjusted its segment reporting composition in the current period in accordance with SFAS 131. The Company’s reporting segments were modified to more accurately reflect the way the Company manages and assesses the performance of the business. The segments were changed to report the banking operations on a state-by-state basis rather than on a per bank basis, as was done in the past, and the Company also created new segments to report the asset management and credit card operations. Previously, the asset management operations were included in “Other” and the credit card operations were included in “Torrey Pines Bank.”

The new structure is segmented as “Nevada” (Bank of Nevada and First Independent Bank of Nevada), “Arizona” (Alliance Bank of Arizona), “California” (Torrey Pines Bank and Alta Alliance Bank), “Asset Management” (Miller/Russell, Premier Trust and Shine), “Credit Card Services” (PartnersFirst) and “Other” (Western Alliance Bancorporation holding company and miscellaneous). Prior period balances were restated to reflect the change.

Transactions between segments consist primarily of borrowings and loan participations. Federal funds purchases and sales and other borrowed funds transactions result in profits that are eliminated for

reporting consolidated results of operations. Loan participations are recorded at par value with no resulting gain or loss. The Company allocates centrally provided services to the operating segments based upon estimated usage of those services.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2007 and our unaudited consolidated financial statements and related footnotes in the Quarterly Report on Form 10-Q. Unless the context requires otherwise, the terms “Company”, “us”, “we”, and “our” refer to Western Alliance Bancorporation on a consolidated basis.

Forward-Looking Information

Certain statements contained in this document, including, without limitation, statements containing the words “believes”, “anticipates”, “intends”, “expects”, “should” and words of similar import, constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Act of 1934. Such forward looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such factors include, among others, the following: general economic and business conditions in those areas in which we operate, demographic changes, competition, fluctuations in interest rates, changes in business strategy or development plans, changes in governmental regulation, credit quality, the availability of capital to fund the expansion of our business, and other factors referenced in this Report. Except as required by law, we disclaim any obligation to update any such factors or to publicly announce the results of any revisions to any of the forward-looking statements contained herein to reflect future events or developments.

Overview

During the third quarter of 2008, our earnings continue to be challenged by difficult economic conditions in our primary markets and the economic downturn generally causing heavy reserves to our loan portfolio and losses in our securities portfolio. We continue to explore and invest in new and expanded business lines and products, including cash management services, credit cards, wealth management and equipment financing. Loan growth for the quarter ended September 30, 2008 was $72.6 million, or 1.9%, as compared to $157.6 million, or 4.7% for the same period in 2007. Customer funds (customer deposits and customer repurchase agreements) decreased $34.9 million to $3.80 billion for the quarter ended September 30, 2008, comprised of a $144.7 million decrease in deposits and a $109.8 million increase in customer repurchase agreements. We reported a net loss of $94.7 million, or ($2.84) loss per diluted share, for the quarter ended September 30, 2008, as compared to net income of $11.1 million, or $0.35 per diluted share, for the same period in 2007. The decrease in earnings is primarily due to securities impairment charges of $20.9 million (net of tax) related to overall decline in financial markets and institutions, a non-cash goodwill impairment charge of $79.2 million and a $10.8 million increase to the provision for loan losses from the previous year due to challenging economic conditions in our primary markets. Non-interest income excluding changes in fair value of financial instruments measured at fair value, for the quarter ended September 30, 2008 increased 24.2% to $7.4 million from the same period in the prior year, due to increases in trust and investment advisory fees, service charges and other revenue. Non-interest expense for the quarter ended September 30, 2008, not including the goodwill impairment charges of $79.2 million, increased 17.4% from the same period in 2007, due primarily to increases in salaries and benefits and occupancy costs related to the growth of the PartnersFirst affinity credit card division and

23

continued branch expansion during 2007 and early 2008. We expect to open one office in Los Angeles, California in the fourth quarter of 2008.

On October 24, 2008, the Company announced its third quarter 2008 financial results in a press release and Form 8-K, which included earnings per share data. The reported earnings per share data included basic net loss per share of $2.84, diluted net loss per share of $2.78 and diluted net operating income per share of $0.16 for the three months ended September 30, 2008. For the nine months ended September 30, 2008, the Company reported basic net loss per share of $2.86, diluted net loss per share of $2.79 and diluted net operating income per share of $0.49. The correct diluted net loss per share for the three and nine months ended September 30, 2008 is $2.84 and $2.86, respectively. All other earnings per share ratios were correct as reported.

Selected financial highlights are presented in the table below.

Primary Factors in Evaluating Financial Condition and Results of Operations

As a bank holding company, we focus on several factors in evaluating our financial condition and results of operations, including:

• Return on Average Equity (ROE) and Return on Average Tangible Equity (ROTE);

• Return on Average Assets (ROA) and Return on Average Tangible Assets (ROTA);

• Asset Quality;

• Asset and Deposit Growth; and

• Operating Efficiency.

Return on Average Equity. Our net income for the three months ended September 30, 2008 decreased $105.8 million to a $94.7 million net loss compared to $11.1 million net income for the three months ended September 30, 2007. The decrease in net income was due primarily to securities impairment charges of $20.9 million (net of tax), a non-cash goodwill impairment charge of $79.2 million and a $10.8 million increase to the provision for loan losses caused by challenging economic conditions in our primary markets, partially offset by a $9.5 million decrease in interest expense due to lower costs of funds. Basic loss per share was $2.84 per share for the three months ended September 30, 2008 compared to $0.38 basic earnings per share for the same period in 2007. Diluted loss per share was $2.84 per share for the three month period ended September 30, 2008, compared to $0.35 diluted earnings per share for the same period in 2007. The decrease in net income and the increase in equity resulted in an ROE of (71.63)% for the three months ended September 30, 2008 compared to 8.46% for the three months ended September 30, 2007. ROTE decreased to (131.90)% for the three months ended September 30, 2008 compared to 15.99% for the three months ended September 30, 2007.

Our net income for the nine months ended September 30, 2008 decreased $118.6 million to a $88.2 million net loss compared to $30.4 million net income for the nine months ended September 30, 2007. The decrease in net income was due primarily to securities impairment charges of $24.4 million (net of tax) related to overall decline in financial markets and institutions, a non-cash goodwill impairment charge of $79.2 million and a $29.5 million increase to the provision for loan losses caused by challenging economic conditions in our primary markets, partially offset by a $11.3 million increase in net interest income and a $5.2 million increase in non-interest income excluding securities and fair value gains (losses). Basic loss per share was $2.86 per share for the nine months ended September 30, 2008 compared to $1.06 basic earnings per share for the same period in 2007. Diluted loss per share was $2.86 per share for the nine month period ended September 30, 2008, compared to $0.98 diluted earnings per share for the same period in 2007. The decrease in net income and the increase in equity resulted in an ROE and ROTE of (23.06)% and (43.68)%, respectively, for the nine months ended September 30, 2008 compared to 8.40% and 14.84%, respectively, for the nine months ended September 30, 2007.

27

Return on Average Assets. Our ROA for the three and nine months ended September 30, 2008 decreased to (7.23)% and (2.27)%, respectively, compared to 0.90% for both of the same periods in 2007. The ROTA for the three and nine months ended September 30, 2008 decreased to (7.58)% and (2.38)%, respectively, compared to 0.95% and 0.94% for the three and nine months ended September 30, 2007. The decreases in ROA and ROTA are primarily due to the decreases in net income as discussed above.

Asset Quality. For all banks and bank holding companies, asset quality plays a significant role in the overall financial condition of the institution and results of operations. We measure asset quality in terms of nonaccrual and restructured loans and assets as a percentage of gross loans and assets, and net charge-offs as a percentage of average loans. Net charge-offs are calculated as the difference between charged-off loans and recovery payments received on previously charged-off loans. As of September 30, 2008, impaired loans, including nonaccrual loans, were $43.9 million compared to $16.3 million at September 30, 2007. Non-accrual loans as a percentage of gross loans were 0.71% as of September 30, 2008, compared to 0.46% as of September 30, 2007. For the three and nine months ended September 30, 2008, net charge-offs as a percentage of average loans were 1.65% and 0.98%, respectively. For the same periods in 2007, net charge-offs as a percentage of average loans were 0.07% and 0.14%, respectively.

Asset Growth. The ability to produce loans and generate deposits is fundamental to our asset growth. Our assets and liabilities are comprised primarily of loans and deposits, respectively. Total assets increased 4.5% to $5.23 billion as of September 30, 2008 from $5.00 billion as of September 30, 2007. Gross loans grew 11.3% to $3.95 billion as of September 30, 2008 from $3.55 billion as of September 30, 2007. Total deposits decreased 7.5% to $3.51 billion as of September 30, 2008 from $3.79 billion as of September 30, 2007.

Operating Efficiency. Operating efficiency is measured in terms of how efficiently income before income taxes is generated as a percentage of revenue. Excluding the goodwill impairment charge, our tax-equivalent efficiency ratio (non-interest expenses divided by the sum of net interest income and non interest income, tax adjusted) for the three and nine months ended September 30, 2008 was 70.5% and 69.8%, respectively, compared to 65.1% and 63.9%, respectively, for the same periods in 2007. The increase was primarily driven by increases in salaries and benefits and occupancy costs associated with the growth of the PartnersFirst affinity credit card division 2007 and continued branch expansion during 2007 and early 2008.

Critical Accounting Policies

The Notes to Audited Consolidated Financial Statements for the year ended December 31, 2007 contain a summary of our significant accounting policies, including discussions on recently issued accounting pronouncements, our adoption of them and the related impact of their adoption. We believe that certain of these policies, along with various estimates that we are required to make in recording our financial transactions, are important to have a complete picture of our financial position. In addition, these estimates require us to make complex and subjective judgments, many of which include matters with a high degree of uncertainty. The discussion of these critical accounting policies and significant estimates can be found in Note 1 of the Audited Consolidated Financial Statements filed with the Company’s Annual Report on Form 10-K.

Results of Operations

Our results of operations depend substantially on net interest income, which is the difference between interest income on interest-earning assets, consisting primarily of loans receivable, securities and other short-term investments, and interest expense on interest-bearing liabilities, consisting primarily of deposits and borrowings. Our results of operations are also dependent upon our generation of noninterest income, consisting primarily of income from trust and investment advisory services and banking service fees. Other factors contributing to our results of operations include our provisions for loan losses, gains or losses on sales of securities and income taxes, as well as the level of our noninterest expenses, such as compensation and benefits, occupancy and equipment and other miscellaneous operating expenses.

The following table sets forth a summary financial overview for the three and nine months ended September 30, 2008 and 2007:

The $105.8 million decrease in net income for the three months ended September 30, 2008 compared with the same period in 2007 was attributable primarily to securities impairment charges of $20.9 million (net of tax) due mainly to widening of credit spreads, which negatively affected the market values of our trust preferred CDO and adjustable rate preferred stock portfolios, a non-cash goodwill impairment charge of $79.2 million based on the assessment that goodwill was significantly impaired and a $10.8 million

29

increase to the provision for loan losses related to the challenging economic conditions in our primary markets, partially offset by a $9.5 million decrease in interest expense due to lower costs of funds compared with the same period in 2007. Net income for the nine months ended September 30, 2008 decreased $118.6 million over the same period in 2007 due to the above mentioned items as well.

Net Interest Income and Net Interest Margin.The 6.6% increase in net interest income for the three months ended September 30, 2008 compared with the same period in 2007 was due to a decrease in interest expense of $9.5 million in excess of the $6.4 million decrease in interest income.

Net interest income for the nine months ended September 30, 2008 increased 8.4% over the same period in 2007. This was due to a decrease in interest expense of $12.4 million in excess of the $1.1 million decrease in interest income, reflecting the effect of a 1.27% decrease in average costs of funds.

The average yield on our interest-earning assets was 6.45% and 6.57% for the three and nine months ended September 30, 2008, respectively, compared to 7.50% and 7.52% for the same periods in 2007. The decrease in the yield on our interest-earning assets is primarily a result of a decrease in market rates, repricing on our adjustable rate loans, and new loans originated with lower interest rates due to the lower interest rate environment.

The cost of our average interest-bearing liabilities decreased to 2.58% and 2.86% in the three and nine months ended September 30, 2008, respectively, from 4.14% and 4.13% in the three and nine months ended September 30, 2007, respectively, which is a result of lower rates paid on deposit accounts and borrowings due to a lower interest rate environment.

Average Balances and Average Interest Rates.The tables below set forth balance sheet items on a daily average basis for the three and nine months ended September 30, 2008 and 2007 and present the daily average interest rates earned on assets and the daily average interest rates paid on liabilities for such periods. Nonaccrual loans have been included in the average loan balances. Securities include securities available-for-sale, securities held-to-maturity and securities carried at market value pursuant to SFAS 159 elections. Yields on tax-exempt securities and loans are computed on a tax equivalent basis.

Provision for Loan Losses.The provision for loan losses in each period is reflected as a charge against earnings in that period. The provision is equal to the amount required to maintain the allowance for loan losses at a level that, in our judgment, is adequate to absorb probable loan losses inherent in the loan portfolio.

Our provision for loan losses was $14.7 million and $35.9 million for the three and nine months ended September 30, 2008, respectively, compared to $3.9 million and $6.4 million the same periods in 2007. Factors that impact the provision for loan losses are net charge-offs or recoveries, changes in the size and mix of the loan portfolio, the recognition of changes in current risk factors and specific reserves on impaired loans.

Non-Interest Income.We earn non-interest income primarily through fees related to:

33

• Trust and investment advisory services,

• Services provided to deposit customers, and

• Services provided to current and potential loan customers.

The following tables present, for the periods indicated, the major categories of non-interest income, excluding securities and fair value gains (losses):

	Three Months Ended							Nine Months Ended

Non-interest income, excluding securities and fair value gains (losses)	$	7,380	$	5,940	$	1,440		$	22,750	$	17,548	$	5,202

The $1.4 million and $5.2 million, or 24.2% and 29.6%, respectively, increases in non-interest income excluding net investment securities gains and net unrealized gain/loss on assets and liabilities measured at fair value from the three and nine months ended September 30, 2007 to the same periods in 2008 were due primarily to increases in investment advisory revenues, service-related charges and operating lease income.

Assets under management at Miller/Russell and Associates were $1.26 billion at September 30, 2008, down 21.3% from $1.60 billion at September 30, 2007. At Premier Trust, assets under management increased 18.8% from $276 million to $328 million from September 30, 2007 to September 30, 2008. On July 31, 2007, we acquired a majority interest in Shine Investment Advisory Services. Assets under management were $410 million as of the acquisition date and $384 million on September 30, 2008. The net growth in assets under management resulted in 1.3% and 19.3% increases, respectively, in trust and advisory fee revenue for the three and nine month periods ending September 30, 2008.

Service charges increased 26.6% and 26.8%, or $0.3 million and $0.9 million, respectively, from the three and nine months ended September 30, 2007 to the same periods in 2008 due to increased analysis and fee charges on deposit accounts.

Other income increased 132.0% and 88.3% from the three and nine months ended September 30, 2007 to the same periods in 2008 due primarily to increases in operating lease income, credit card charges and affinity income related to growth of our operations, as well as non-recurring income amounts of approximately $1.1 million.

Unrealized gains/losses on assets and liabilities measured at fair value. During the three and nine month periods ended September 30, 2008, we recognized net unrealized gains of $5.3 million and net unrealized gains of $7.3 million, respectively, on assets and liabilities measured at

34

fair value. These gains are primarily the result of gains on our trust preferred liabilities due to a widening of interest rate spreads. We view the majority of these gains as temporary in nature since the changes in value on most of our financial instruments were not related to a change in credit profile, but rather such gains were the result of fluctuations in market yields.

Non-Interest Expense.The following table presents, for the periods indicated, the major categories of non-interest expense:

	Three Months Ended							Nine Months Ended

Noninterest expense grew $85.3 million and $99.1 million, respectively, from the three and nine months ended September 30, 2007 to the same periods in 2008. These increases are attributable specifically to a $79.2 million non-cash goodwill impairment, our overall growth, and to merger and acquisition activity and the opening of new branches. At September 30, 2008, we had 1,017 full-time equivalent employees compared to 987 at September 30, 2007.

Intangible amortization increased $0.7 million and $1.6 million, respectively, from the three months and nine months ended September 30, 2007 to the same periods in 2008 as a result of decreases in the estimated amortizable lives of the core deposit intangibles acquired through prior acquisitions.

Other noninterest expense increased, in general, as a result of the growth in assets and operations of our banking subsidiaries, including the acquisitions of First Independent and Shine.

Financial Condition

Total Assets

35

On a consolidated basis, our total assets as of September 30, 2008 and December 31, 2007 were $5.23 billion and $5.02 billion, respectively. Assets experienced growth from the period ending September 30, 2007 to the period ending September 30, 2008 of $225.5 million, or 4.5%, including loan growth of $400.7 million, or 11.3%.

Loans

Our gross loans including deferred loan fees on a consolidated basis as of September 30, 2008 and December 31, 2007 were $3.95 billion and $3.63 billion, respectively. Our overall growth in loans from December 31, 2007 to September 30, 2008 is a result of targeting quality credit customers in our markets.

The following table shows the amounts of loans outstanding by type of loan at the end of each of the periods indicated:

Non-Performing Assets

Non-performing assets include loans past due 90 days or more and still accruing interest, non-accrual loans, restructured loans, and other real estate owned, or OREO. In general, loans are placed on nonaccrual status when we determine timely recognition of interest to be in doubt due to the borrower’s financial condition and collection efforts. Restructured loans have modified terms to reduce either principal or interest due to deterioration in the borrower’s financial condition. OREO results from loans where we have received physical possession of the borrower’s assets that collateralize the loan.

Impaired loans are loans for which it is probable that the Company will not be able to collect all amounts due according to the original contractual terms of the loan agreement. Other impaired loans include certain loans that are classified as substandard or doubtful for which it is probable full payment of principal and interest according to the contractual terms of the loan agreement will not be received.

As of September 30, 2008 and December 31, 2007, non-accrual loans totaled $27.9 million and $17.9 million, respectively. Nonaccrual loans at September 30, 2008 consisted of 69 loans.

OREO increased $9.3 million for the nine months ended September 30, 2008 to $12.7 million. This increase in 2008 was due to higher foreclosure volume and a longer period of time required to sell properties in the current market.

Allowance for Loan Losses

Like all financial institutions, we must maintain an adequate allowance for loan losses. The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when we believe that collectibility of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. The allowance is an amount that we believe will be adequate to absorb probable losses on existing loans that may become uncollectible, based on evaluation of the collectibility of loans and prior credit loss experience, together with the other factors noted earlier.

Our allowance for loan loss methodology incorporates several quantitative and qualitative risk factors used to establish the appropriate allowance for loan loss at each reporting date. Quantitative factors include our historical loss experience, peer group experience, delinquency and charge-off trends, collateral values, changes in non-performing loans, other factors, and information about individual loans including the borrower’s sensitivity to interest rate movements. Qualitative factors include the economic condition of our operating markets and the state of certain industries. Specific changes in the risk factors are based on perceived risk of similar groups of loans classified by collateral type, purpose and terms. Statistics on local trends, peers, and an internal five-year loss history are also incorporated into the allowance. Due to the credit concentration of our loan portfolio in real estate secured loans, the value of collateral is heavily dependent on real estate values in Nevada, Arizona and California. While management uses the best information available to make its evaluation, future adjustments to the allowance

37

may be necessary if there are significant changes in economic or other conditions. In addition, the Federal Deposit Insurance Corporation, or FDIC, and state banking regulatory agencies, as an integral part of their examination processes, periodically review the Banks’ allowance for loan losses, and may require us to make additions to the allowance based on their judgment about information available to them at the time of their examinations. Management periodically reviews the assumptions and formulae used in determining the allowance and makes adjustments if required to reflect the current risk profile of the portfolio.

The allowance consists of specific and general components. The specific allowance relates to impaired loans. For such loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan, pursuant to SFAS 114,Accounting by Creditors for Impairment of a Loan. The general allowance covers non-impaired loans and is based on historical loss experience adjusted for the various qualitative and quantitative factors listed above, pursuant to SFAS 5,Accounting for Contingencies.

The following table summarizes the activity in our allowance for loan losses for the period indicated:

Net charge-offs totaled $16.3 million and $0.6 million for the three months ended September 30, 2008 and 2007, respectively. For the nine months ended September 30, 2008 and 2007, net

38

charge-offs totaled $28.1 million and $3.4 million, respectively. The provision for loan losses totaled $14.7 million and $35.9 million for the three and nine months ended September 30, 2008, respectively, compared to $3.9 million and $6.4 million for the same periods in 2007. The increase in the provision for loan losses is due to higher historical losses, changes in size and mix of the loan portfolio and increases in specific reserves on impaired loans.

Investments

Securities are identified as either held-to-maturity, available-for-sale, or measured at fair value based upon various factors, including asset/liability management strategies, liquidity and profitability objectives, and regulatory requirements. Held-to-maturity securities are carried at cost, adjusted for amortization of premiums or accretion of discounts. Available-for-sale securities are securities that may be sold prior to maturity based upon asset/liability management decisions. Securities identified as available-for-sale are carried at fair value. Unrealized gains or losses on available-for-sale securities are recorded as accumulated other comprehensive income in stockholders’ equity. Amortization of premiums or accretion of discounts on mortgage-backed securities is periodically adjusted for estimated prepayments. Securities measured at fair value are reported at fair value, with unrealized gains and losses included in current earnings.

We use our investment securities portfolio to ensure liquidity for cash requirements, manage interest rate risk, provide a source of income and to manage asset quality. The carrying value of our investment securities as of September 30, 2008 totaled $622.0 million, compared to $736.2 million at December 31, 2007.

In 2007 and 2008 we maintained a high level of investment in mortgage-backed securities while shifting from U.S. Government agency obligations to higher yielding debt obligations (primarily collateralized debt obligations secured by bank and other financial company trust preferred liabilities) and adjustable rate preferred stock of bank and other financial companies.

The carrying value of our portfolio of investment securities at September 30, 2008 and December 31, 2007 was as follows:

	Carrying Value
	At September 30,		At December 31,
	2008		2007
	(in thousands)
U.S. Treasury securities	$	8,172	$	—
U.S. Government-sponsored agencies		14,722		24,128
Mortgage-backed obligations		437,635		502,784
State and Municipal obligations		19,467		22,211
Adjustable rate preferred stock		45,891		29,710
Debt obligations and structured securities		81,167		142,127
Other		14,953		15,240
Total investment securities	$	622,007	$	736,200

As of May 31, 2008, the Company transferred its trust preferred CDO portfolio from available-for-sale to held-to-maturity. The Company considers the held-to-maturity classification to be more appropriate because it has the ability and the intent to hold these securities to maturity. The

39

par value and fair value of these securities at the date of transfer were $121.4 million and $85.7 million, respectively. The unrealized losses of $35.7 million on the securities transferred to held-to-maturity remain in other comprehensive loss and continue to be subject to the other-than-temporary impairment consideration rules of SFAS No. 115,Accounting for Certain Investments in Debt and Equity Securities.

Net unrealized losses, net of taxes, increased $23.3 million for the nine months ended September 30, 2008 to $52.1 million from $28.7 million at December 31, 2007. The increase in unrealized losses is generally due to widening interest spreads which began in the third quarter of 2007. During March 2008, the near insolvency of Bear Stearns, followed by the collapse of several major financial institutions in the third quarter of 2008 caused the debt of almost all financial companies to decline in value. This compounded the lack of liquidity for such securities that existed since late 2007. The Company is actively monitoring these portfolios for declines in fair value that are considered other-than-temporary. These combined unrealized losses were not considered as other-than-temporary as of September 30, 2008.

The Company conducts an other-than-temporary impairment analysis on a quarterly basis. The initial indication of other-than-temporary impairment for both debt and equity securities is a decline in the market value below the amount recorded for an investment, and the severity and duration of the decline. In determining whether an impairment is other than temporary, the Company considers the length of time and the extent to which the market value has been below cost, recent events specific to the issuer, including investment downgrades by rating agencies and economic conditions of its industry, and the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery. For marketable equity securities, the Company also considers the issuer’s financial condition, capital strength, and near-term prospects. For debt securities and for perpetual preferred securities that are treated as debt securities for the purpose of other-than-temporary analysis, the Company also considers the cause of the price decline (general level of interest rates and industry- and issuer-specific factors), the issuer’s financial condition, near-term prospects and current ability to make future payments in a timely manner, the issuer’s ability to service debt, and any change in agencies’ ratings at evaluation date from acquisition date and any likely imminent action.

Gross unrealized losses at September 30, 2008 are primarily caused by interest rate changes, credit spread widening and reduced liquidity in applicable markets. The Company has reviewed securities on which there is an unrealized loss in accordance with its accounting policy for other-than-temporary impairment described above and recorded impairment charges totaling $38.0 million. This includes a $19.8 million impairment charge related to unrealized losses in the Company’s CDO portfolio, $15.2 million related to impairment losses in the Company’s adjustable rate preferred stock portfolio (ARPS) and $3.1 million related to an auction-rate leveraged security that was discussed in the Company’s Form 10-K for the year ended December 31, 2007.

The Company does not consider any other securities to be other-than-temporarily impaired. However, without recovery in the near term such that liquidity returns to the applicable markets and spreads return to levels that reflect underlying credit characteristics, additional other-than-temporary impairments may occur in future periods. At September 30, 2008, the Company had the ability and intent to hold all securities in the available-for-sale portfolio that have significant unrealized losses.

40

Goodwill

The Company recorded $217.8 million of goodwill from its merger-related activities during 2006 and 2007. In accordance with SFAS No. 141, goodwill is not amortized but rather tested for impairment annually. Impairment testing consists of comparing the fair value of the acquired reporting units with their carrying amounts, including goodwill. An impairment loss would be recorded to the extent the carrying value of the goodwill exceeds the fair value of the goodwill. At September 30, 2008, it was determined the implied fair value of the goodwill related to the acquisition of the FICN reporting unit was less than the carrying value on the Company’s balance sheet, which is one factor that is considered when determining goodwill impairment. Based on the assessment that goodwill was significantly impaired, we wrote down the $79.2 million of goodwill related to the FICN reporting unit, incurring a non-cash impairment charge. The remaining goodwill was also tested for impairment during the third quarter 2008; however, no impairment was deemed necessary based on the results of the testing.

Deposits

Deposits have historically been the primary source for funding our asset growth. As of September 30, 2008, total deposits were $3.51 billion, compared to $3.55 billion as of December 31, 2007. Our deposits related to customer relationships decreased approximately $98 million, and we acquired third party brokered certificates of deposit totaling approximately $60 million. Other time deposits were $318.4 million as of September 30, 2008, compared to $66.5 million as of December 31, 2007. The increase was due primarily to $150.7 million in new deposits associated with our certificate of deposit account registry service (CDARS), a $40.0 million increase in certificates of deposits (in the under $100 million category), and the acquired $60 million of brokered certificates of deposit mentioned above. We do not anticipate utilizing brokered deposits as a significant source of funding in future periods.

Although we expect deposit growth to continue to be the primary source of funding the asset growth of the Company, we anticipate further augmenting our liquidity through the use of alternative sources of funding, including overnight and term advances from the Federal Home Loan Bank and Federal Reserve Bank, repurchase agreements, subordinated debt and lines of credit.

The following table provides the average balances and weighted average rates paid on deposits for the three and nine months ended September 30, 2008:

Our customer repurchases increased $20.4 million to $295.4 million from December 31, 2007 to September 30, 2008.

Liquidity

The goals of our liquidity management are to ensure the ability of the Company to meet its financial commitments when contractually due and to respond to other demands for funds such as the ability to meet the cash flow requirements of customers who may be either depositors wanting to withdraw funds or borrowers who may need assurance that sufficient funds will be available to meet their credit needs.

Historically, the Company’s primary liquidity source has been its core deposit base. Over the past few months the Company’s reliance on collateralized FHLB and FRB borrowings has increased as one of its sources of affordable and immediately available liquidity. The level of such wholesale funding is monitored based on the Company’s liquidity requirements, and we maintain at all times what we believe to be an acceptable level of this collateralized borrowing capacity. The Company’s secured borrowing capacity was $1.34 billion, of which $607 million was available as of September 30, 2008. In addition to the secured borrowing relationship with the FHLB and FRB, the Company maintains adequate balances in liquid assets, which include cash and due from banks, Federal Funds sold, interest-bearing deposits in other financial institutions, and unpledged loans and investment securities available-for-sale. The Company also maintains unsecured lines of credit, subject to availability, of $140.0 million with correspondent banks for purchase of overnight funds. Another source of liquidity is the holding company’s $15.0 million revolving line of credit, all of which was available as of September 30, 2008.

The recent disruption in the financial credit and liquidity markets has had the effect of decreasing overall liquidity in the marketplace. While we have experienced modest net outflows of customer funds, we have augmented our funding needs with collateralized FHLB and FRB borrowings as well as CDARs and other brokered deposits. At September 30, 2008, the Company had $151.3 million of CDARs time deposits and $60.0 million of brokered time deposits, the availability of which is uncertain and subject to competitive market forces.

Capital Resources

Current risk-based regulatory capital standards generally require banks and bank holding companies to maintain three minimum capital ratios. Tier 1 risk-based capital ratio compares “Tier 1” or “core” capital, which consists principally of common equity, and risk-weighted assets for a minimum ratio of at least 4%. Tier 1 capital ratio compares Tier 1 capital to adjusted total assets for a minimum ratio of at least 4%. Total risk-based capital ratio compares total capital, which consists of Tier 1 capital, certain forms of subordinated debt, a portion of the allowance for loan losses, and preferred stock, to risk-weighted assets for a minimum ratio of at least 8%. Risk-weighted assets are calculated by multiplying the balance in each category of assets by a risk factor, which ranges from zero for cash assets and certain government obligations to 100% for some types of loans, and adding the products together.

The following table provides a comparison of our risk-based capital ratios and leverage ratios to the minimum regulatory requirements as of September 30, 2008:

						Adequately-					Minimum For
						Capitalized					Well-Capitalized
	Actual					Requirements					Requirements
	($ in thousands)
As of September 30, 2008	Amount		Ratio			Amount		Ratio			Amount		Ratio
Total Capital (to Risk Weighted Assets)	$	537,557		11.4	%	$	376,898		8.0	%	$	471,123		10.0	%
Tier I Capital (to Risk Weighted Assets)	$	420,198		8.9	%	$	188,449		4.0	%	$	282,674		6.0	%
Leverage ratio (to Average Assets)	$	420,198		8.3	%	$	202,251		4.0	%	$	252,813		5.0	%

The Company and each of its banking subsidiaries met the “well capitalized” guidelines under regulatory requirements as of September 30, 2008. The increases in our capital ratios for the quarter ended September 30, 2008, are primarily due to a private placement of approximately 4.3 million shares of common stock to a limited number of accredited investors at a price of $11.50 per share, resulting in gross proceeds to the company of $50 million before deducting offering expenses.

Segment Reporting

The Company adjusted its segment reporting composition in the current year in accordance with SFAS 131. We modified our reporting segments to more accurately reflect the way we manage and assess the performance of our business. We changed our segments to report our banking operations on a state-by-state basis rather than on a per bank basis, as we had done in the past, and we also created new segments to report our asset management and credit card operations. Previously, our asset management operations were included in “Other” and our credit card operations were included in “Torrey Pines Bank.”
The new structure is segmented as “Nevada” (Bank of Nevada and First Independent Bank of Nevada), “Arizona” (Alliance Bank of Arizona), “California” (Torrey Pines Bank and Alta Alliance Bank), “Asset Management” (Miller/Russell, Premier Trust and Shine), “Credit Card Services” (PartnersFirst) and “Other” (Western Alliance Bancorporation holding company and miscellaneous). Prior period balances were restated to reflect the change.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of loss in a financial instrument arising from adverse changes in market prices and rates, foreign currency exchange rates, commodity prices and equity prices. Our market risk arises primarily from interest rate risk inherent in our lending, investing and deposit taking activities. To that end, management actively monitors and manages our interest rate risk exposure.

There have not been any material changes in the market risk disclosure contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.
