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), synthetic CDOs and related embedded derivatives; 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 June 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.

Notes to Unaudited Consolidated Financial Statements
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 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 audited financial statements.
Repurchase program
For the six months ended June 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
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 applies to endorsement split dollar life insurance policies that provide a benefit to an employee that extends to postretirement periods and 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 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 March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (SFAS 161). SFAS 161 amends and expands the disclosure requirements of FASB Statement No. 133, requiring enhanced disclosures about (a) how and why the Company uses derivative instruments, (b) how derivative instruments and related hedge items are accounted for under FASB Statement No. 133 and its related interpretations, and (c) how derivative instruments and related hedged items affect the Company’s financial position, results of operations, and cash flows. SFAS 161 is effective January 1, 2009 on a prospective basis, with comparative disclosures of earlier periods encouraged upon initial adoption.
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, or 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 in

computing earnings per share, or EPS, under the two-class method described in paragraphs 60 and 61 of FASB Statement No. 128, Earnings per Share, or 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 an 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
For the three and six months ended June 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 $54.3 million and the aggregate unpaid principal balance of $66.5 million of junior subordinated debt was $12.2 million at June 30, 2008.
The difference between the aggregate fair value of $30.8 million and the aggregate unpaid principal balance of $30.0 million of fixed-rate term borrowings measured at fair value was $0.8 million at June 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 June 30, 2008 (in thousands):

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 June 30, 2008.

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, the resulting fair value measurement has been categorized as a Level 3 measurement. These Level 3 impaired loans had an aggregate carrying amount of $59.1 million and specific reserves in the allowance for loan losses of $12.8 million as of June 30, 2008.
Note 3. Earnings Per Share
Diluted earnings per share is based on the weighted average outstanding common shares during each period, including common stock equivalents. Basic earnings per share is based on the weighted average outstanding common shares during the period.

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 No. 115, Accounting for Certain Investments in Debt and Equity Securities.
Net unrealized losses, net of taxes, increased $17.4 million for the six months ended June 30, 2008 to $46.1 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 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 June 30, 2008.
During the six months ended June 30, 2008, the Company recorded impairment charges totaling $5.3 million, including $2.2 million related to a security which suffered a significant downgrade 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.

Note 10. 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 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.
The following is a summary of selected operating segment information as of and for the periods ended June 30, 2008 and 2007:

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 second 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 leasing, and we believe the current economic climate presents our Company with the opportunity to differentiate ourselves from our competitors. Loan growth for the quarter ended June 30, 2008 was $151.9 million, or 4.1%, as compared to growth of $52.9 million, or 1.6% for the same period in 2007. Deposit growth was $23.4 million, including $60.0 million of brokered deposits, or 0.6%, for the three months ended June 30, 2008, compared to growth of $33.3 million, or 0.9% for the same period in 2007. We reported net income of $2.4 million, or $0.08 per diluted share, for the quarter ended June 30, 2008, as compared to $7.9 million, or $0.25 per diluted share, for the same period in 2007. The decrease in earnings is primarily due to an increase of $4.9 million in noninterest expenses related to expansion efforts and an $11.1 million increase in the provision for loan losses related to higher historical losses, changes in size and mix of the loan portfolio and increases in specific reserves on impaired loans. Noninterest income, excluding changes in fair value of financial instruments measured at fair value, for the quarter ended June 30, 2008 increased 15.5% from the same period in the prior year due to increases in trust and investment advisory fees, service charges and other revenue. Noninterest expense for the quarter ended June 30, 2008 increased 14.3% from the same period in 2007, due primarily to increases in salaries and benefits and occupancy costs caused by the acquisitions of Shine Investment Advisory Services in 2007, the establishment of the PartnersFirst affinity credit card initiative in 2007 and continued branch expansion during 2007. Branch expansion is expected to be nominal through the remainder of 2008.
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 Tangible Average Equity (ROTE);
 
    Return on Average Assets (ROA) and Return on Average Tangible Assets (ROTA);
 
    Asset Quality;

    Operating Efficiency.
Return on Average Equity. Our net income for the three months ended June 30, 2008 decreased 69.6% to $2.4 million compared to $7.9 million for the three months ended June 30, 2007. The decrease in net income was due primarily to an $11.1 million increase to the provision for loan losses caused by challenging economic conditions in our primary markets, partially offset by a $6.3 million decrease in interest expense due to lower costs of funds. Basic earnings per share decreased to $0.08 per share for the three months ended June 30, 2008 compared to $0.27 per share for the same period in 2007. Stockholders’ equity increased $31.5 million from the quarter ended March 31, 2008 due primarily to a private placement of 3.8 million shares of common stock totaling $30.2 million. Diluted earnings per share was $0.08 per share for the three month period ended June 30, 2008, compared to $0.25 per share for the same period in 2007. The decrease in net income and the increase in equity resulted in an ROE of 1.95% for the three months ended June 30, 2008 compared to 6.15% for the three months ended June 30, 2007. ROTE decreased 65.0% to 3.79% for the three months ended June 30, 2008.
Our net income for the six months ended June 30, 2008 decreased 66.1% to $6.6 million compared to $19.3 million for the six months ended June 30, 2007. Basic earnings per share decreased to $0.22 per share for the six months ended June 30, 2008 compared to $0.68 per share for the same period in 2007. Diluted earnings per share was $0.21 per share for the six month period ended June 30, 2008, compared to $0.63 per share for the same period in 2007. The decrease in net income combined with the increase in equity resulted in an ROE and ROTE of 2.64% and 5.07%, respectively, for the six months ended June 30, 2008 compared to 8.37% and 13.75%, respectively, for the six months ended June 30, 2007.
Return on Average Assets. Our ROA for the three and six months ended June 30, 2008 decreased to 0.19% and 0.26%, respectively, compared to 0.68% and 0.89%, respectively, for the same periods in 2007. The ROTA for the three and six months ended June 30, 2008 decreased to 0.20% and 0.27%, respectively, compared to 0.71% and 0.93%, respectively, for the three and six months ended June 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 June 30, 2008, impaired loans, including nonaccrual loans, were $59.1 million compared to $8.0 million at June 30, 2007. Nonaccrual loans as a percentage of gross loans were 1.15% as of June 30, 2008, compared to less than 0.02% as of June 30, 2007. For the three and six months ended June 30, 2008, net charge-offs as a percentage of average loans were 0.55% and 0.63%, respectively. For the same periods in 2007, net charge-offs as a percentage of average loans were 0.31% and 0.18%.
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 10.0% to $5.22 billion as of June 30, 2008 from $4.75 billion as of June 30, 2007. Gross loans grew 14.3% to $3.87 billion as of June 30, 2008 from $3.39 billion as of June 30, 2007. Total deposits decreased 4.2% to $3.65 billion as of June 30, 2008 from $3.82 billion as of June 30, 2007.

Operating Efficiency. Operating efficiency is measured in terms of how efficiently income before income taxes is generated as a percentage of revenue. Our tax-equivalent efficiency ratio (noninterest expenses divided by the sum of net interest income and noninterest income, tax adjusted) was 70.68% for the three months ended June 30, 2008, compared to 64.23% for the same period in 2007. Our tax-equivalent efficiency ratios for the six months ended June 30, 2008 and 2007 were 69.43% and 63.16%, respectively. The increase was primarily driven by increases in salaries and benefits and occupancy costs associated with the acquisitions of First Independent Bank of Nevada and Shine Investment Advisory Services in 2007, the establishment of the PartnersFirst affinity credit card initiative in 2007 and continued branch expansion during 2007.
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 69.6% decrease in net income for the three months ended June 30, 2008 compared to the same period in 2007 was attributable primarily to an $11.1 million increase to the provision for loan losses caused by challenging economic conditions in our primary markets, partially offset by a $6.3 million decrease in interest expense due to lower costs of funds. Net income for the six months ended June 30, 2008 and June 30, 2007 decreased $12.8 million from $19.3 million, which is due to the above mentioned items as well.
Net Interest Income and Net Interest Margin. The 4.7% increase in net interest income for the three months ended June 30, 2008 compared to the same period in 2007 was due to a decrease in interest expense of $6.3 million in excess of the $4.2 million decrease in interest income.
Net interest income for the six months ended June 30, 2008 increased 9.4% over the same period in 2007 due to an increase in interest income of $5.3 million, reflecting the effect of an increase of $689.0 million in average interest-bearing assets which was funded primarily with an increase of $159.3 million in average deposits and $684.9 million in average short-term borrowings and due to a decrease in interest expense of $2.9 million, reflecting the effect of a 1.13% decrease in average costs of funds.
The average yield on our interest-earning assets was 6.41% and 6.63% for the three and six months ended June 30, 2008, respectively, compared to 7.56% and 7.54% 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 2.68% and 3.00% in the three and six months ended June 30, 2008, respectively, from 4.14% and 4.13% in the three and six months ended June 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 six months ended June 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.

29


Table of Contents

Our provision for loan losses was $13.2 million and $21.2 million for the three and six months ended June 30, 2008, respectively, compared to $2.0 million and $2.5 million for 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.
Noninterest Income. We earn noninterest income primarily through fees related to:
    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 noninterest income:

Non-interest income, excluding securities and fair value gains (losses)
  $ 6,952     $ 6,019     $ 933     $ 15,370     $ 11,608     $ 3,762  
         
The $0.9 million and $3.8 million, or 15.5% and 32.4%, respectively, increases in noninterest income excluding net investment securities gains and net unrealized gain/loss on assets and liabilities measured at fair value, from the three and six months ended June 30, 2007 to the same periods in 2008 was due to increases in investment advisory revenues, increases in service-related charges and other revenue.
Assets under management at Miller/Russell and Associates were $1.31 billion at June 30, 2008, down 17.1% from $1.58 billion at June 30, 2007. At Premier Trust, assets under management increased 26.6% from $259 million to $328 million from June 30, 2007 to June 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 $403 million on June 30, 2008. This growth resulted in 28.0% and 30.4% increases, respectively, in trust and advisory fee revenue for the three and six month periods ending June 30, 2008, as compared to the three and six month periods ending June 30, 2007.
Service charges increased 20.9% and 26.9% or $0.2 million and $0.6 million, respectively, from the three and six months ended June 30, 2007 to the same periods in 2008 due to higher deposit balances and the growth in our customer base.

Other income increased 27.3% and 73.6% from the three and six months ended June 30, 2007 to the same periods in 2008 due primarily to the growth of the company and its operations, as well as non-recurring income amounts of approximately $1.1 million, including a gain on the sale of a foreclosed property of approximately $0.4 million.
Unrealized gains/losses on assets and liabilities measured at fair value. During the three and six month periods ended June 30, 2008, we recognized net unrealized losses of $0.1 million and net unrealized gains of $1.3 million, respectively, on assets and liabilities measured at fair value. These gains and losses are primarily the result of losses caused by changes in market yields on securities similar to those in our portfolio, offset by a gain on our trust preferred liabilities due to a widening of interest rate spreads. We view the majority of these gains and losses 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 and losses were the result of fluctuations in market yields.

Noninterest expense grew $4.9 million and $13.9 million, respectively, from the three and six months ended June 30, 2007 to the same periods in 2008. These increases are attributable to our overall growth, and specifically to merger and acquisition activity and the opening of new branches. At June 30, 2008 and at June 30, 2007, we had 1,000 full-time equivalent employees.
Intangible amortization increased $0.4 million and $0.9 million, respectively, from the three months and six months ended June 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
On a consolidated basis, our total assets as of June 30, 2008 and December 31, 2007 were $5.22 billion and $5.02 billion, respectively. Assets experienced growth from the period ending June 30, 2007 to the period ending June 30, 2008 of $472.5 million, or 10.0%, including loan growth of $485.6 million, or 14.3%.
Loans
Our gross loans including deferred loan fees on a consolidated basis as of June 30, 2008 and December 31, 2007 were $3.87 billion and $3.63 billion, respectively. Our overall growth in loans from December 31, 2007 to June 30, 2008 is a result of targeting quality credit customers in our markets.

Non-Performing Assets
Non-performing assets include loans past due 90 days or more and still accruing interest, nonaccrual 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 collateralized 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 for which the original terms have been extended or modified, but which are well collateralized and for which no loss is expected.
The following table summarizes the loans for which the accrual of interest has been discontinued, loans past due 90 days or more and still accruing interest, restructured loans, other impaired loans and OREO.

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

33


Table of Contents

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 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.

Net charge-offs totaled $5.3 million and $2.7 million for the three months ended June 30, 2008 and 2007, respectively. For the six months ended June 30, 2008 and 2007, net charge-offs totaled $11.8 million and $2.8 million, respectively. The provision for loan losses totaled $13.2 million and $21.2 million for the three and six months ended June 30, 2008, respectively, compared to $2.0 million and $2.5 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 June 30, 2008 totaled $621.7 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 June 30, 2008 and December 31, 2007 was as follows:

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 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 $17.4 million for the six months ended June 30, 2008 to $46.1 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 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. We are actively monitoring these portfolios for declines in fair value that are considered other-than-temporary. If current market conditions persist, we may have impairment charges against earnings next quarter for declines in securities fair values that are considered other-than-temporary.

During the six months ended June 30, 2008, we recorded impairment charges totaling $5.3 million, including $2.2 million related to a security which suffered a significant downgrade and $3.1 million related to an auction-rate leveraged security that was discussed in our Form 10-K for the year ended December 31, 2007.
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 on October 1. 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 June 30, 2008, the Company’s market capitalization was less than the total shareholders’ equity, which is one factor that is considered when determining goodwill impairment. If current market conditions persist, it is possible that we will have a goodwill impairment charge against earnings in a future period.
Deposits
Deposits have historically been the primary source for funding our asset growth. As of June 30, 2008, total deposits were $3.65 billion, compared to $3.55 billion as of December 31, 2007. Our deposits related to customer relationships increased approximately $47 million, and we acquired third party brokered certificates of deposit totaling approximately $60 million. 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 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.

Our customer repurchases declined $89.4 million from December 31, 2007 to June 30, 2008 due primarily to the transfer of customer funds to other products offered by our banks.
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 Company and each of its banking subsidiaries met the “well capitalized” guidelines under regulatory requirements as of June 30, 2008. The increases in our capital ratios for the quarter ended June 30, 2008, are primarily due to a private placement of 3.8 million shares of common stock to a limited number of accredited investors. Of the shares sold, approximately 45 percent were purchased by a total of 40 directors and officers of the Company and its subsidiaries. The issue was priced after the close of business on Tuesday, June 24, 2008 at $7.94 per share for an aggregate offering price of $30.2 million.
Segment Reporting
The Company adjusted its segment reporting composition in the current period 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.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls
Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, the Chief Executive Officer and Chief Financial Officer have concluded that the disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported in within the time periods specified in Securities and Exchange Commission rules and forms, except for the following:
Changes in Internal Control over Financial Reporting
There have not been any changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2008, which have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
