Notes to Unaudited Consolidated Financial Statements

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

Nature of business

Western Alliance Bancorporation is a bank holding company providing a full range of banking services to commercial and consumer customers through its wholly owned subsidiaries Bank of Nevada (formerly BankWest of Nevada), operating in Nevada, Alliance Bank of Arizona, operating in Arizona, Torrey Pines Bank, operating in Southern California, Miller/Russell & Associates, Inc., operating in Nevada, Arizona and Southern California, and Premier Trust, Inc., operating in Nevada and Arizona. 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.

A summary of the significant accounting policies of the Company follows:

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. A material estimate that is particularly susceptible to significant change in the near term relates to the determination of the allowance for loan losses. Additionally, the defalcation discussed in Note 9 required management to estimate a loss before a full investigation had been completed.

Principles of consolidation

The consolidated financial statements include the accounts of Western Alliance Bancorporation and its wholly owned subsidiaries, Bank of Nevada, Alliance Bank of Arizona, Torrey Pines Bank (collectively referred to herein as the Banks), Miller/Russell & Associates, Inc., and Premier Trust, Inc. Nevada First Bank was acquired on March 31, 2006, and as a result was included in the consolidated balance sheet as of that date. During the quarter ended June 30, 2006, Nevada First Bank was merged into Bank of Nevada, the surviving entity. All significant intercompany balances and transactions have been eliminated in consolidation.

Interim financial information

The accompanying unaudited consolidated financial statements as of June 30, 2006 and 2005 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.

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.

Condensed financial information as of December 31, 2005 has been presented next to the interim consolidated balance sheet for informational purposes.

Note 1. Nature of Business and Summary of Significant Accounting Policies (continued)

Stock compensation plans

The Company has the 2005 Stock Incentive Plan (the Plan) which is described more fully in Note 7. Effective January 1, 2006 (the adoption date), the Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2005), Share Based Payment (SFAS 123R). Prior to adoption of SFAS 123R, the Company accounted for stock option grants using the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. No stock option-based compensation was reflected in net income, as all options are required by the Plan to be granted with an exercise price equal to the estimated fair value of the underlying common stock on the date of grant.

Prior to the adoption of SFAS 123R, the Company applied the disclosure provisions of SFAS 123,Accounting for Stock-Based Compensation. SFAS 123 required the disclosure of the pro forma impact on net income and earnings per share if the value of the options were calculated at fair value. SFAS 123 permitted private companies to calculate the fair value of stock options using the minimum value method while public companies were required to use a fair value model. Prior to the Company’s initial public offering (IPO) the Company used the minimum value method to calculate the fair value of stock options. Subsequent to the Company’s IPO, the Company utilizes the Black-Scholes model to calculate the fair value of stock options.

The Company has adopted SFAS 123R using the prospective method for options granted prior to the IPO and the modified prospective method for options granted subsequent to the IPO. Under the Company’s transition method, SFAS 123R applies to new awards and to awards that were outstanding on the adoption date that are subsequently modified, repurchased, or cancelled. In addition, the expense recognition provision of SFAS 123R applies to options granted prior to the adoption date but subsequent to the IPO that were unvested at the adoption date.

The following table illustrates the effect on net income and earnings per share had compensation cost for all of the stock-based compensation plans been determined based on the grant date fair values of awards (the method described in FASB Statement No. 123, Accounting for Stock-Based Compensation):

Recent accounting pronouncements

In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement 109 (FIN 48), which clarifies the accounting for uncertainty in tax positions. This Interpretation provides that the tax effects from an uncertain tax position can be recognized in our financial statements only if the position is more likely than not of being sustained on audit, based on the technical merits of the position. The provisions of FIN 48 are effective for fiscal years beginning after December 15, 2006, with the cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. We do not expect FIN 48 to have a material impact on our financial statements.

Note 2. Merger and Acquisition Activity

Effective March 31, 2006, the Company acquired 100% of the outstanding common stock of Intermountain First Bancorporation (Intermountain), headquartered in Las Vegas, Nevada. Intermountain was the parent company of Nevada First Bank. The tax-free merger was accomplished according to the Agreement and Plan of Merger (the Merger Agreement), dated December 30, 2005. At the date of acquisition, Nevada First Bank became a wholly-owned subsidiary of the Company, and on April 29, 2006, Nevada First Bank was merged into BankWest of Nevada. As the merger closed on March 31, 2006, Intermountain’s results for the three months ended March 31, 2006 were not included with the Company’s results of operations. The merger increases the Company’s presence in Las Vegas, Nevada and expands the Company’s market into Northern Nevada.

As provided by the Merger Agreement and based on valuation amounts determined as of the merger date, approximately 1.486 million shares of Intermountain common stock were exchanged for $6.85 million in cash and 3.39 million shares of the Company’s common stock at a calculated exchange ratio of 2.44. The exchange of shares represented approximately 13% of the Company’s outstanding common stock as of the merger date.

Intermountain had 57,150 employee stock options outstanding at the acquisition date (March 31, 2006). All of the Intermountain stock options vested upon change in control. On the acquisition date, the

Note 2. Merger and Acquisitions Activity (continued)

Company replaced the Intermountain stock options with options to purchase shares of the Company’s stock. In order to determine the number of options to be granted, the number of Intermountain options was multiplied by the exchange ratio of 2.44 and the exercise price was divided by the exchange ratio. All other terms (vesting, contractual life, etc.) were carried forward from the Intermountain options. As a result, the Company granted a total of 139,446 stock options with a weighted average exercise price of $7.70 to former Intermountain employees on the acquisition date. The fair value of the stock options of $3.4 million is included in the purchase price.

The merger was accounted for under the purchase method of accounting in accordance with Statement of Financial Accounting Standard No. 141, Business Combinations. Accordingly, the purchase price was allocated to the assets acquired and the liabilities assumed based on their estimated fair values at the merger date (March 31, 2006) as summarized below (in thousands, except share and per share amounts):

Effective April 29, 2006, the Company acquired 100% of the outstanding common stock of Bank of Nevada, headquartered in Las Vegas, Nevada. The tax-free merger was accomplished according to the Agreement and Plan of Merger (the Bank of Nevada Merger Agreement), dated January 16, 2006. At the date of acquisition, Bank of Nevada was merged into BankWest of Nevada (whose name was subsequently changed to Bank of Nevada). As the merger closed on April 29, 2006, Bank of Nevada’s results for the one month ended April 30, 2006 were not included with the Company’s results of operations. The merger increases the Company’s presence in Las Vegas, Nevada.

As provided by the Bank of Nevada Merger Agreement, approximately 844,000 shares of Bank of Nevada common stock and 119,000 stock options were exchanged for $74.0 million in cash.

The merger was accounted for under the purchase method of accounting in accordance with Statement of Financial Accounting Standard No. 141, Business Combinations.

Note 6. Commitments and Contingencies

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.

Financial instruments with off-balance sheet risk

The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. They involve, to varying degrees, elements of credit risk in excess of amounts recognized on the consolidated balance sheets.

17

Western Alliance Bancorporation and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

Note 6. Commitments and Contingencies (continued)

Financial instruments with off-balance sheet risk (continued)

The Company’s exposure to credit loss in the event of nonperformance by the other parties to the financial instrument for these commitments is represented by the contractual amounts of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. A summary of the contract amount of the Company’s exposure to off-balance sheet risk is as follows:


	June 30,		December 31,
	2006		2005
	(in thousands)
Commitments to extend credit, including unsecured loan commitments of $239,218 in 2006 and $111,522 in 2005	$	1,133,067	$	750,349
Credit card guarantees		7,008		7,616
Standby letters of credit, including unsecured letters of credit of $15,288 in 2006 and $4,550 in 2005		45,028		28,720

	$	1,185,103	$	786,685

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate and income-producing commercial properties.

The Company guarantees certain customer credit card balances held by an unrelated third party. These unsecured guarantees act to streamline the credit underwriting process and are issued as a service to certain customers who wish to obtain a credit card from the third party vendor. The Company recognizes nominal fees from these arrangements and views them strictly as a means of maintaining good customer relationships. The guarantee is offered to those customers who, based solely upon management’s evaluation, maintain a relationship with the Company that justifies the inherent risk. Essentially all such guarantees exist for the life of each respective credit card relationship. The Company would be required to perform under the guarantee upon a customer’s default on the credit card relationship with the third party. Historical losses under the program have been nominal. Upon entering into a credit card guarantee, the Company records the related liability at fair value pursuant to FASB Interpretation No. 45 (FIN 45), Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.Thereafter, the related liability is evaluated pursuant to FASB 5. The total of such credit card balances outstanding at June 30, 2006 and December 31, 2005 (in thousands) are $1,203 and $1,566, respectively. During the second quarter of 2006, the Company began offering its own credit card product and will no longer guarantee new credit cards under the arrangement as described above.

Western Alliance Bancorporation and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

Note 6. Commitments and Contingencies (continued)

Financial instruments with off-balance sheet risk (continued)

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral held varies as specified above and is required as the Company deems necessary. Essentially all letters of credit issued have expiration dates within one year. Upon entering into a letter of credit, the Company records the related liability at fair value pursuant to FIN 45. Thereafter, the related liability is evaluated pursuant to FASB 5.

The total liability for financial instruments with off-balance sheet risk as of June 30, 2006 and December 31, 2005 was (in thousands) $826 and $455, respectively.

Concentrations

The Company grants commercial, construction, real estate and consumer loans to customers through offices located in the Company’s primary markets. The Company’s business is concentrated in these areas and the loan portfolio includes significant credit exposure to the commercial real estate industry of these areas. At June 30, 2006, commercial real estate related loans accounted for approximately 66% of total loans, and approximately 8% of real estate loans are secured by undeveloped land. Substantially all of these loans are secured by first liens with an initial loan to value ratio of generally not more than 80%. Approximately one-half of real estate loans are owner occupied. In addition, approximately 6% and 5% of total loans are unsecured as of June 30, 2006 and December 31, 2005, respectively. Approximately 30% of our residential real estate loan portfolio is comprised of five and ten year interest only loans. The loans have an average loan-to-value of less than 60% and convert to fully-amortizing adjustable rate mortgages at the end of the interest-only period.

The commercial and commercial real estate loans are expected to be repaid from business cash flows or proceeds from the sale of selected assets of the borrowers. The Company’s policy for requiring collateral is to obtain collateral whenever it is available or desirable, depending upon the degree of risk the Company is willing to take.

At June 30, 2006, approximately $366.5 million of the Company’s non-interest bearing demand deposits consisted of demand accounts maintained by title insurance companies.

Note 7. Stock Options and Restricted Stock

During 2005, the stockholders approved the 2005 Stock Incentive Plan (the Plan). The Plan is an amendment and restatement of our prior stock compensation plans, and therefore supersedes the prior plans while preserving the material terms of the prior plan awards. The Plan gives the Board of Directors the authority to grant up to 3,253,844 stock awards consisting of unrestricted stock, stock units, dividend equivalent rights, stock options (incentive and non-qualified), stock appreciation rights, restricted stock, and performance and annual incentive awards. Stock awards available to grant at June 30, 2006 are 373,211.

The Plan contains certain individual limits on the maximum amount that can be paid in cash under the Plan and on the maximum number of shares of common stock that may be issued pursuant to the Plan in a calendar year. The maximum number of shares subject to options or stock appreciation rights that can be issued under the Plan to any person is 150,000 shares in any calendar year. The maximum number of shares that can be issued under the Plan to any person, other than pursuant to an option or stock appreciation right, is 150,000 in any calendar year. The maximum amount that may be earned as an annual incentive award or other cash award in any fiscal year by any one person is $5.0 million and the maximum amount that may be earned as a performance award or other cash award in respect of a performance period by any one person is $15.0 million.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model that uses the assumptions noted in the following table. The expected volatility is based on the historical volatility of the stock of similar companies that have traded at least as long as the expected life of the Company’s options. The Company estimates the life of the options by calculating the average of the vesting period and the contractual life. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The dividends rate assumption of zero is based on management’s intention not to pay dividends for the foreseeable future. A summary of the assumptions used in calculating the fair value of option awards during the three and six months ended June 30, 2006 and 2005 is as follows:

Stock options granted in 2005 generally have a vesting period of 4 years and a life of 7 years. Restricted stock granted in 2005 generally has a vesting period of 3 years. The Company recognizes compensation cost for options with a graded vesting on a straight-line basis over the requisite service period for the entire award.

Note 9. Employee Defalcation

On July 26, 2006, the Company identified evidence of an employee defalcation pertaining to certain accounts at a branch office of its Bank of Nevada (formerly BankWest of Nevada) subsidiary. The alleged defalcation involved improper draws and payments on legitimate notes and the creation of fraudulent loans, resulting in fraudulent balances and the potential for legitimate loans with undetected credit problems. The Company understands the employee made payments on impaired credits to avoid scrutiny of other loans in the affected portfolio. The Company is reflecting an estimate of the loss resulting from this defalcation in its results of operations for the three months ended June 30, 2006, as reported herein.

Although investigation of the fraud is still underway, the Company has recognized a net pretax loss of $898,000, including loan losses from impaired credits which were being concealed from management of $527,000 as well as other operating losses from fraudulent loans of $371,000. This amount is net of restitution the Company has secured from the former employee, which include cash payments, assignments of proceeds from the liquidation of certain retirement and profit sharing plans, and the former employee’s personal residence. While we do not currently believe our losses will materially exceed the amount accrued in our results of operations for the three months ended June 30, 2006, we will not have a definitive quantification of the loss until we complete an internal investigation by the end of the third quarter of 2006. In addition, the Company maintains an insurance policy which management believes covers the Company’s fraud losses from this incident.

Note 10. Subsequent Events

In July 2006, the Company issued a Private Placement Offering Memorandum with the intent of issuing $10,000,000 in common stock. The offering has not been completed as of the date of this filing. The proceeds from this offering will be used to capitalize the proposed de novo bank in Oakland, California.

Overview

During the second quarter of 2006, we remained focused on increasing our earnings through growth of our interest earning assets funded with low-cost deposits. Organic loan growth for the quarter ended June 30, 2006 was $181.6 million, or 9.3%, as compared to $121.5 million, or 9.1% for the same period in 2005. At June 30, 2006, gross loans acquired in the Intermountain and Bank of Nevada mergers were $642.5 million. Organic deposit growth was $57.5 million, or 2.3%, for the three months ended June 30, 2006, compared to $170.9 million, or 8.5% for the same period in 2005. Total deposits acquired in the Intermountain and Bank of Nevada mergers were $605.6 million. We reported net income of $11.0 million, or $0.38 per diluted share, for the quarter ended June 30, 2006, as compared to $6.6 million, or $0.32 per diluted share, for the same period in 2005. The increase in earnings is primarily due to higher net interest income, due primarily to an increase in loans and the increase in interest rates. The provision for loan losses increased $742,000 from the three months ended June 30, 2005 to the same period in 2006, due to stronger loan growth. Non-interest income for the quarter ended June 30, 2006 increased 53.6% from the same period in the prior year, due to increases in trust and investment advisory fees, service charges and income from bank owned life insurance. Non-interest expense for the quarter ended June 30, 2006 increased 55.1% from the same period in 2005, due primarily to increases in salaries and benefits, occupancy and customer service costs caused by continued branch expansion and the acquisitions of Nevada First Bank and Bank of Nevada.

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, or ROE;

	•		Return on Average Tangible Equity, or ROTE;

	•		Return on Average Assets, or ROA;

	•		Asset Quality;

	•		Asset and Deposit Growth; and

	•		Operating Efficiency.

Return on Average Equity. Our net income for the three months ended June 30, 2006 increased 66.0% to $10.9 million compared to $6.6 million for the three months ended June 30, 2005. The increase in net income was due primarily to an increase in net interest income of $15.0 million, an increase in non-interest income of $1.6 million, offset by increases of $1.3 million and $8.6 million to the provision for loan losses and in other expenses, respectively. Basic earnings per share increased to $0.41 per share for the three months ended June 30, 2006 compared to $0.35 per share for the same period in 2005. Diluted earnings per share was $0.38 per share for the three month periods ended June 30, 2006, compared to $0.32 per share for the same period in 2005. The increase in net income offset by the increase in equity resulted in an ROE and ROTE of 12.02% and 18.63%, respectively, for the three months ended June 30, 2006 compared to 17.71% and 18.37%, respectively, for the three months ended June 30, 2005.

Our net income for the six months ended June 30, 2006 increased 62.7% to $19.3 million compared to $11.9 million for the six months ended June 30, 2005. The increase in net income was due primarily to an increase in net interest income of $22.5 million and an increase in non-interest income of $2.5 million, offset by an increase of $13.6 million in other expenses. Basic earnings per share increased to $0.79 per share for the six months ended June 30, 2006 compared to $0.65 per share for the same period in 2005. Diluted earnings per share was $0.71 per share for the six month periods ended June 30, 2006, compared to $0.59 per share for the same period in 2005. The increase in net income offset by the increase in equity resulted in an ROE and ROTE of 12.72% and 16.30%, respectively, for the six months ended June 30, 2006 compared to 16.53% and 17.16%, respectively, for the six months ended June 30, 2005.

Return on Average Assets. Our ROA for the three and six months ended June 30, 2006 increased to 1.16% and 1.18%, respectively, compared to 1.10% and 1.05%, respectively, for the same periods in 2005. The increases in ROA are primarily due to the increases 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 non-accrual and restructured loans and assets as a percentage of

29

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, 2006, non-accrual loans were $20,000 compared to $503,000 at June 30, 2005. Non-accrual loans as a percentage of gross loans were less than 0.01% as of June 30, 2006, compared to 0.03% as of June 30, 2005. For the three and six months ended June 30, 2006, net charge-offs/ (recoveries) as a percentage of average loans were 0.02% and (0.01%), respectively. For the same periods in 2005, net charge-offs as a percentage of average loans were 0.01% for each period.

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 48.4% to $3.9 billion as of June 30, 2006 from $2.6 billion as of June 30, 2005. Gross loans grew 90.8% (46.6% organically) to $2.8 billion as of June 30, 2006 from $1.5 billion as of June 30, 2005. Total deposits increased 46.1% (18.4% organically) to $3.2 billion as of June 30, 2006 from $2.2 billion as of June 30, 2005.

Operating Efficiency. Operating efficiency is measured in terms of how efficiently income before income taxes is generated as a percentage of revenue. Our efficiency ratio (non-interest expenses divided by the sum of net interest income and non interest income) was 55.8% for the three months ended June 30, 2006, compared to 58.5% for the same period in 2005. Our efficiency ratios for the six months ended June 30, 2006 and 2005 were 57.3% and 58.9%, respectively.

Critical Accounting Policies

The Notes to Audited Consolidated Financial Statements for the year ended December 31, 2005 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 following is a discussion of these critical accounting policies and significant estimates. Additional information about these policies can be found in Note 1 of the Audited Consolidated Financial Statements filed with the Company’s Annual Report on Form 10-K.

Allowance for Loan Losses. The allowance for loan losses is a valuation allowance for probable losses incurred in the loan portfolio. Our allowance for loan loss methodology incorporates a variety of risk considerations in establishing an allowance for loan loss that we believe is adequate to absorb losses in the existing portfolio. Such analysis addresses our historical loss experience, delinquency and charge-off trends, collateral values, changes in nonperforming loans, economic conditions, peer group experience and other considerations. This information is then analyzed to determine “estimated loss factors” which, in turn, are assigned to each loan category. These factors also incorporate known information about individual loans, including the borrowers’ sensitivity to interest rate movements. Changes in the factors themselves are driven by perceived risk in pools of homogenous loans classified by collateral type, purpose and term. Management monitors local trends to anticipate future delinquency potential on a quarterly basis. In addition to ongoing internal loan reviews and risk assessment, management utilizes an independent loan review firm to provide advice on the appropriateness of the allowance for loan losses.

30

The allowance for loan losses is increased by the provision for loan losses charged to expense and reduced by loans charged off, net of recoveries. Provisions for loan losses are provided on both a specific and general basis. Specific allowances are provided for classified and impaired credits for which the expected/anticipated loss may be measurable. General valuation allowances are based on a portfolio segmentation based on collateral type, purpose and risk grading, with a further evaluation of various factors noted above.

We incorporate our internal loss history to establish potential risk based on collateral type securing each loan. As an additional comparison, we examine peer group banks to determine the nature and scope of their losses. Finally, we closely examine each credit graded “Watch List/Special Mention” and below to individually assess the appropriate specific loan loss reserve for such credit.

At least annually, we review the assumptions and formulae by which additions are made to the specific and general valuation allowances for loan losses in an effort to refine such allowance in light of the current status of the factors described above. The total loan portfolio is thoroughly reviewed at least quarterly for satisfactory levels of general and specific reserves together with impaired loans to determine if write downs are necessary.

Although we believe the level of the allowance as of June 30, 2006 was adequate to absorb probable losses in the loan portfolio, a decline in local economic or other factors could result in increasing losses that cannot be reasonably estimated at this time. Also, we have not completed our analysis of the loan portfolio affected by the defalcation, as discussed below and as such, additional losses could result.

Available-for-Sale Securities. Statement of Financial Accounting Standards No. 115,Accounting for Certain Investments in Debt and Equity Securities, requires that available-for-sale securities be carried at fair value. Management utilizes the services of a third party vendor to assist with the determination of estimated fair values. Adjustments to the available-for-sale securities fair value impact the consolidated financial statements by increasing or decreasing assets and stockholders’ equity.

Stock Based Compensation. Effective January 1, 2006 (the adoption date), the Company adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share Based Payment (SFAS 123R). Prior to adoption of SFAS 123R, the Company accounted for stock option grants using the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. No stock-based compensation was reflected in net income, as all options are required by the Plan to be granted with an exercise price equal to the estimated fair value of the underlying common stock on the date of grant.

Prior to the adoption of SFAS 123R, the Company applied the disclosure provisions of SFAS 123,Accounting for Stock-Based Compensation. SFAS 123 required the disclosure of the pro forma impact on net income and earnings per share if the value of the options were calculated at fair value. SFAS 123 permitted private companies to calculate the fair value of stock options using the minimum value method while public companies were required to use a fair value model. Prior to the Company’s initial public offering (IPO) the Company used the minimum value method to calculate the fair value of stock options. Subsequent to the Company’s IPO, the Company utilizes the Black-Scholes model to calculate the fair value of stock options.

The Company has adopted SFAS 123R using the prospective method for options granted prior to the IPO and the modified prospective method for options granted subsequent to the IPO. Under the Company’s transition method, SFAS 123R applies to new awards and to awards that were outstanding on the adoption date that are subsequently modified, repurchased, or cancelled. In addition, the expense recognition provision of SFAS 123R applies to options granted prior to the adoption date but subsequent to the IPO that were unvested at the adoption date.

Beginning in 2006, the Company’s stock-based compensation strategy involves granting restricted stock to key employees and stock options to senior executives. Prior to 2006, key employees were primarily granted stock options.

As of June 30, 2006, there was (in thousands) $8,484 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted average period of 3.3 years.

Intangible assets. We closed our acquisitions of Intermountain First Bancorp and Bank of Nevada on March 31 and April 29, 2006, respectively. A portion of the purchase prices of Intermountain First Bancorp and Bank of Nevada have been allocated to core deposit intangible. These intangible assets are initially recorded at fair value as determined by a qualified independent valuation specialist engaged by management. We will amortize these intangible assets over their estimated useful lives. In addition, we will reassess the fair value of these assets each reporting period to determine whether any impairment losses should be recognized.

Defalcation. On July 26, 2006, the Company identified evidence of an employee defalcation pertaining to certain accounts at a branch office of its Bank of Nevada (formerly BankWest of Nevada) subsidiary. The alleged defalcation involved improper draws and payments on legitimate notes and the creation of fraudulent loans, resulting in fraudulent balances and the potential for legitimate loans with undetected credit problems. The Company understands the employee made payments on impaired credits to avoid scrutiny of other loans in the affected portfolio. The Company is reflecting an estimate of the loss resulting from this defalcation in its results of operations for the three months ended June 30, 2006, as reported herein.

Although investigation of the fraud is still underway, the Company has recognized a net pretax loss of $898,000, including loan losses from impaired credits which were being concealed from management of $527,000 as well as other operating losses from fraudulent loans of $371,000. This amount is net of restitution the Company has secured from the former employee, which include cash payments, assignments of proceeds from the liquidation of certain retirement and profit sharing plans, and the former employee’s personal residence. While we do not currently believe our losses will materially exceed the amount accrued in our results of operations for the three months ended June 30, 2006, we will not have a definitive quantification of the loss until we complete an internal investigation by the end of the third quarter of 2006. In addition, the Company maintains an insurance policy which management believes covers the Company’s fraud losses from this incident.

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

32

operations are also dependent upon our generation of non-interest income, consisting 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 non-interest expenses, such as compensation and benefits, occupancy and equipment and other miscellaneous operating expenses.

The 66.0% increase in net income in the three months ended June 30, 2006 compared to the same period in 2005 was attributable primarily to an increase in net interest income of $15.2 million and an increase in non-interest income of $1.6 million, offset by an increase of $8.6 million in other expenses and an increase to the provision for loan losses of $1.3 million. Net income for the six months ended June 30, 2006 increased 62.7% over the same period in 2005, which is due to an increase in net interest income of $22.5 million and an increase in non-interest income of $2.5 million, offset by an increase in non-interest expenses of $13.6 million. The increases in net interest income for the three and six months ended June 30, 2006 over the same periods for 2005 were the result of an increase in the volume of and yield earned on interest-earning assets, primarily loans.

Net Interest Income and Net Interest Margin. The 62.2% increase in net interest income for the three months ended June 30, 2006 compared to the same period in 2005 was due to an increase in interest income of $27.6 million, reflecting the effect of an increase of $1.1 billion in average interest-bearing assets which was primarily funded with an increase of $960.4 million in average deposits, of which $227.0 million were non-interest bearing.

Net interest income for the six months ended June 30, 2006 increased 48.6% over the same period in 2005. This was due to an increase in interest income of $22.5 million, reflecting the effect of an increase of $866.5 million in average interest-bearing assets which was primarily

33

funded with increase of $747.7 million in average deposits, of which $185.8 million were non-interest bearing.

The average yield on our interest-earning assets was 7.09% and 6.82% for the three and six months ended June 30, 2006, respectively, compared to 5.73% and 5.68% for the same periods in 2005. The increase in the yield on our interest-earning assets is a result of an increase in market rates, repricing on our adjustable rate loans, and new loans originated with higher interest rates due to the higher interest rate environment. Additionally, the loan portfolios of Nevada First Bank and Bank of Nevada, both of which were acquired in the six months ended June 30, 2006, generally yielded more than the loan portfolio held by the former BankWest of Nevada. Loans, which typically yield more than our other interest-bearing assets, increased as a percent of total interest-bearing assets from 62.0% for the three months ended June 30, 2005 to 79.9% for the same period in 2006.

The cost of our average interest-bearing liabilities increased to 3.47% and 3.26% in the three and six months ended June 30, 2006, respectively, from 2.14% and 2.06% in the three and six months ended June 30, 2005, respectively, which is a result of higher rates paid on deposit accounts, borrowings and junior subordinated debt caused by the steady upward pressure on short-term interest rates driven by the Federal Open Market Committee’s (FOMC) rate increases. Due in part to our acquisitions, we have also seen a shift in our deposit mix whereby non-interest bearing deposits comprise a smaller percentage of our entire deposit portfolio, thus increasing our funding costs. Average non-interest bearing deposits as a percent of deposits declined from 41.2% for the three months ended June 30, 2005 to 35.6% for the same period in 2006.

Despite the increase in our cost of funding, we have experienced steady margin expansion since the FOMC began raising interest rates. We anticipate that such expansion will become more difficult to achieve as long as the yield curve remains flat and alternate sources of funding such as subordinated debt become a more significant part of our funding mix. Furthermore, we expect modest margin contraction in the third quarter 2006 due to the mid-second quarter close of our acquisition of the former Bank of Nevada for cash, which was not reflected for the entire second quarter.

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, 2006 and 2005 and present the daily average interest rates earned on assets and the daily average interest rates paid on liabilities for such periods. Non-accrual loans have been included in the average loan balances. Securities include securities available for sale and securities held to maturity. Securities available for sale are carried at amortized cost for purposes of calculating the average rate received on taxable securities above. 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 $2.5 million and $3.0 million for the three and six months ended June 30, 2006, respectively, compared to $1.2 million and $2.9 million the same periods in 2005. Factors that impact the provision for loan losses are net charge-offs or

37

recoveries, changes in the size of the loan portfolio, and the recognition of changes in current risk factors. For the three and six months ended June 30, 2006, the provision includes the impact of $542,000 in charged-off credits associated with the employee defalcation.

Non-Interest Income. We earn non-interest 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 non-interest income:


	Three Months Ended						Six Months Ended

Total non-interest income	$	4,482	$	2,918	$	1,564	$	7,979	$	5,502	$	2,477

The $1.6 million and $2.5 million, or 53.6% and 45.0%, respectively, increases in non-interest income from the three and six months ended June 30, 2005 to the same periods in 2006 were due primarily to increases in Miller/Russell investment advisory revenues and income from bank owned life insurance. Assets under management at Miller/Russell were up 41.4% from June 30, 2005 to June 30, 2006, causing the increase in revenues. During the third quarter of 2005, we purchased $24.0 million in bank owned life insurance.

Non-interest expense grew $8.6 million and $13.6 million, respectively, from the three and six months ended June 30, 2005 to the same periods in 2006. These increases are attributable to our overall growth, and specifically to the acquisitions of Nevada First Bank and Bank of Nevada, opening of new branches and hiring of new relationship officers and other employees. At June 30, 2006, we had 717 full-time equivalent employees compared to 497 at June 30, 2005. The increase in salaries expenses related to the above totaled $4.5 million and $7.6 million, respectively, which is 52.5% and 56.1%, respectively, of the total increases in non-interest expenses.

Occupancy expense increased $690,000 and $895,000, respectively, from the three and six months ended June 30, 2005 to the same periods in 2006 due to increased costs associated with new and acquired branches. At June 30, 2006 we operated 26 branch locations, compared with 13 at June 30, 2005.

Customer service expense increased $998,000 and $1.5 million from the three and six month periods ended June 30, 2005 to the same periods in 2006 due to an increase in the analysis earnings credit rate used to calculate earnings credits accrued for the benefit of certain title company deposit accounts.

During the three months ended June 30, 2006, we incurred $428,000 of organizational costs associated with a proposed de novo bank (Alta Alliance Bank [proposed]) in Oakland, California. We anticipate that such costs will continue through the third quarter of 2006, shortly after which we expect Alta Alliance Bank (proposed) to open.

Other expenses increased $666,000, due to losses related to the defalcation of $371,000 and the overall growth of the Company.

39

Other non-interest expense increased, in general, as a result of the growth in assets and operations for our three banking subsidiaries.

Provision for Income Taxes. Our effective federal income tax rate was 36.1% and 35.3% for the three and six months ended June 30, 2006, respectively compared to 35.4% and 35.6%, respectively, for the same periods in 2005.

Defalcation. On July 26, 2006, the Company identified evidence of an employee defalcation pertaining to certain accounts at a branch office of its Bank of Nevada (formerly BankWest of Nevada) subsidiary. The alleged defalcation involved improper draws and payments on legitimate notes and the creation of fraudulent loans, resulting in fraudulent balances and the potential for legitimate loans with undetected credit problems. The Company understands the employee made payments on impaired credits to avoid scrutiny of other loans in the affected portfolio. The Company is reflecting an estimate of the loss resulting from this defalcation in its results of operations for the three months ended June 30, 2006, as reported herein.

Although investigation of the fraud is still underway, the Company has recognized a net pretax loss of $898,000, including loan losses from impaired credits which were being concealed from management of $527,000 as well as other operating losses from fraudulent loans of $371,000. This amount is net of restitution the Company has secured from the former employee, which include cash payments, assignments of proceeds from the liquidation of certain retirement and profit sharing plans, and the former employee’s personal residence. While we do not currently believe our losses will materially exceed the amount accrued in our results of operations for the three months ended June 30, 2006, we will not have a definitive quantification of the loss until we complete an internal investigation by the end of the third quarter of 2006. In addition, the Company maintains an insurance policy which management believes covers the Company’s fraud losses from this incident.

Financial Condition

Total Assets

On a consolidated basis, our total assets as of June 30, 2006 and December 31, 2005 were $3.9 billion and $2.9 billion, respectively. The overall increase from December 31, 2005 to June 30, 2006 of $1.0 billion, or 36.1%, was due primarily to the acquisition of Intermountain First Bancorporation and Bank of Nevada on March 31, 2006 and April 29, 2006, respectively. At June 30, 2006, assets acquired through the Intermountain and Bank of Nevada mergers totaled $845.4 million and gross loans acquired totaled $642.5 million. Assets experienced organic growth during the same period of $187.7 million, or 6.6%, including loan growth of $334.8 million, or 18.7%.

Loans

Our gross loans including deferred loan fees on a consolidated basis as of June 30, 2006 and December 31, 2005 were $2.8 billion and $1.8 billion, respectively. Our overall growth in loans from December 31, 2005 to June 30, 2006 reflects our acquisitions of Intermountain First Bancorporation and Bank of Nevada and is consistent with our focus and strategy to grow our loan portfolio by focusing on markets which we believe have attractive growth prospects.

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 non-accrual 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. 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, 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 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 Southern 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 watch credits, criticized loans, and impaired loans. For such loans that are also 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 Financial Accounting Standards Board, or FASB, Statement No. 114, Accounting by Creditors for Impairment of a Loan. The general allowance covers non-classified loans and is based on historical loss experience adjusted for the various qualitative and quantitative factors listed above, pursuant to FASB Statement No. 5, or FASB 5, Accounting for Contingencies. Loans graded “Watch List/Special Mention” and below are individually examined closely to determine the appropriate loan loss reserve.

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

Net charge-offs totaled $475,000 and $183,000 for the three months ended June 30, 2006 and 2005, respectively. For the six months ended June 30, 2006 and 2005, net charge-offs totaled $397,000 and $87,000, respectively. The provision for loan losses totaled $2.5 million and $3.0 million for the three and six months ended June 30, 2006, respectively, compared to $1.2 million and $2.9 million for the same periods in 2005.

Investments

Securities are identified as either held-to-maturity or available-for-sale 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 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.

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, 2006 totaled $586.9 million, compared to $748.5

43

million at December 31, 2005. The decrease experienced from December 31, 2005 to June 30, 2006 was a result of the maturity of our Auction Rate Securities portfolio and called U.S. Government-sponsored agency obligations.

The carrying value of our portfolio of investment securities at June 30, 2006 and December 31, 2005 was as follows:


	Carrying Value
	At June 30,		At December 31,
	2006		2005

We had a concentration of U.S. Government sponsored agencies and mortgage-backed securities during the three and six months ended June 30, 2006 and the year ended December 31, 2005. The aggregate carrying value and aggregate fair value of these securities at June 30, 2006 and December 31, 2005 was as follows:

Goodwill and other intangible assets

Primarily as a result of the acquisitions of Intermountain First Bancorporation and Bank of Nevada in the six months ended June 30, 2006, we recorded goodwill of $126.7 million and core deposit intangible assets of $13.8 million. These amounts are subject to change when the determination of the asset and liability values is finalized within one year from the respective merger dates.

Deposits

Deposits have historically been the primary source for funding our asset growth. As of June 30, 2006, total deposits were $3.2 billion, compared to $2.4 billion as of December 31, 2005. Deposits acquired as a result of the acquisitions of Intermountain First Bancorporation and Bank of Nevada totaled $605.6 million. The remaining organic increase in total deposits is

44

attributable to our ability to attract a stable base of low-cost deposits. As of June 30, 2006, non-interest bearing deposits were $1.2 billion, compared to $980.0 million as of December 31, 2005. Approximately $366.5 million of total deposits, or 11.5%, as of June 30, 2006 consisted of non-interest bearing demand accounts maintained by title insurance companies. Interest-bearing accounts have also experienced growth. As of June 30, 2006, interest-bearing deposits were $2.0 billion, compared to $1.4 billion as of December 31, 2005. Interest-bearing deposits are comprised of NOW accounts, savings and money market accounts, certificates of deposit under $100,000, and certificates of deposit over $100,000.

The average balances and weighted average rates paid on deposits for the three and six months ended June 30, 2006 and 2005 are presented below:

Contractual Obligations and Off-Balance Sheet Arrangements

We routinely enter into contracts for services in the conduct of ordinary business operations which may require payment for services to be provided in the future and may contain penalty clauses for early termination of the contracts. To meet the financing needs of our customers, we are also parties to financial instruments with off-balance sheet risk including commitments to extend credit and standby letters of credit. We have also committed to irrevocably and unconditionally guarantee the following payments or distributions with respect to the holders of preferred securities to the extent that BankWest Nevada Trust I, BankWest Nevada Trust II, WAL Trust No. 1 and Intermountain First Statutory Trust I have not made such payments or distributions: (i) accrued and unpaid distributions, (ii) the redemption price, and (iii) upon a dissolution or termination of the trust, the lesser of the liquidation amount and all accrued and unpaid distributions and the amount of assets of the trust remaining available for distribution. We do not believe that these off-balance sheet arrangements have or are reasonably likely to have a material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources. However, there can be no assurance that such arrangements will not have a future effect.

Long-Term Borrowed Funds. We also have entered into long-term contractual obligations consisting of advances from Federal Home Loan Bank (FHLB). These advances are

45

secured with collateral generally consisting of securities or loans. As of June 30, 2006, these long-term FHLB advances totaled $78.3 million and will mature by December 31, 2012.

We have issued $20.0 million in floating rate unsecured subordinated debt. The debt requires quarterly interest payments and matures in September 2016.

Our commitments associated with outstanding letters of credit, commitments to extend credit, and credit card guarantees as of June 30, 2006 are summarized below. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements.

	$	1,185,103	$	786,685

Short-Term Borrowed Funds. Short-term borrowed funds are used to support liquidity needs created by seasonal deposit flows, to temporarily satisfy funding needs from increased loan demand, and for other short-term purposes. Certain of these short-term borrowed funds consist of advances from FHLB. The borrowing capacity at FHLB is determined based on collateral pledged, generally consisting of securities, at the time of borrowing. We also have borrowings from other sources pledged by securities including securities sold under agreements to repurchase, which are reflected at the amount of cash received in connection with the transaction, and may require additional collateral based on the fair value of the underlying securities. As of June 30, 2006, total short-term borrowed funds were $138.5 million compared to total short-term borrowed funds of $85.2 million as of December 31, 2005.

Since growth in core deposits may be at intervals different from loan demand, we may follow a pattern of funding irregular growth in assets with short-term borrowings, which are then replaced with core deposits. This temporary funding source is likely to be utilized for generally short-term periods, although no assurance can be given that this will, in fact, occur.

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%. Leverage ratio compares Tier 1 capital to adjusted average 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.

46

The following table provides a comparison of our risk-based capital ratios and leverage ratios to the minimum regulatory requirements as of June 30, 2006.

The holding company and all of the banks were well capitalized as of June 30, 2006 and December 31, 2005.

Liquidity

The ability to have readily available funds sufficient to repay fully maturing liabilities is of primary importance to depositors, creditors and regulators. Our liquidity, represented by cash and due from banks, federal funds sold and available-for-sale securities, is a result of our operating, investing and financing activities and related cash flows. In order to ensure funds are available at all times, on at least a quarterly basis, we project the amount of funds that will be required and maintain relationships with a diversified customer base so funds are accessible. Liquidity requirements can also be met through short-term borrowings or the disposition of short-term assets. We have borrowing lines at correspondent banks totaling $122.4 million. In addition, securities and loans are pledged to the FHLB totaling $314.9 million on total borrowings from the FHLB of $78.3 million as of June 30, 2006. As of June 30, 2006, we had $21.5 million in securities available to be sold or pledged to the FHLB.

We have a formal liquidity policy, and in the opinion of management, our liquid assets are considered adequate to meet our cash flow needs for loan funding and deposit cash

47

withdrawal for the next 60 to 90 days. At June 30, 2006, we had $691.6 million in liquid assets comprised of $224.3 million in cash and cash equivalents (including federal funds sold of $86.8 million) and $470.6 million in securities available-for-sale.

The merger with Intermountain First Bancorporation, which closed on March 31, 2006, resulted in a cash outlay of $6.8 million in the second quarter of 2006. The acquisition of Bank of Nevada, which closed on April 29, 2006, resulted in a cash outlay of $74.0 million in the second quarter of 2006. These outlays were funded with cash on hand, the issuance of $20.0 million of trust preferred securities and a drawdown of $10.0 million on an available line of credit. The line of credit was paid off in the second quarter of 2006 and we issued $20 million in subordinated debt at our Bank of Nevada subsidiary.

On a long-term basis, our liquidity will be met by changing the relative distribution of our asset portfolios, for example, reducing investment or loan volumes, or selling or encumbering assets. Further, we will increase liquidity by soliciting higher levels of deposit accounts through promotional activities and/or borrowing from our correspondent banks as well as the Federal Home Loan Bank of San Francisco. At the current time, our long-term liquidity needs primarily relate to funds required to support loan originations and commitments and deposit withdrawals. All of these needs can currently be met by cash flows from investment payments and maturities, and investment sales if the need arises.

Our liquidity is comprised of three primary classifications: (i) cash flows from operating activities; (ii) cash flows used in investing activities; and (iii) cash flows provided by financing activities. Net cash provided by operating activities consists primarily of net income adjusted for changes in certain other asset and liability accounts and certain non-cash income and expense items such as the loan loss provision, investment and other amortizations and depreciation. For the six months ended June 30, 2006, net cash provided by operating activities was $14.1 million, compared to $14.6 million for the same period in 2005.

Our primary investing activities are the origination of real estate, commercial and consumer loans and purchase and sale of securities. Our net cash used in investing activities has been primarily influenced by our loan and securities activities. The increase in loans, net of loans acquired, for the three months ended June 30, 2006 and 2005 was $369.0 million and $264.8 million, respectively. Proceeds from maturities and sales of securities, net of purchases of securities available-for-sale and held-to-maturity for the six months ended June 30, 2006 and 2005 were $191.5 million and $137.1 million, respectively.

Net cash provided by financing activities has been affected significantly by increases in deposit levels. During the six months ended June 30, 2006 and 2005 deposits increased, net of deposits acquired, by $227.4 million and $433.5 million, respectively.

Our federal funds sold increased $23.7 million from December 31, 2005 to June 30, 2006. This is due to the growth in our deposits and borrowings, including junior subordinated and subordinated debt, combined with the decrease of our investment portfolio exceeding our loan growth over the same period.

Federal and state banking regulations place certain restrictions on dividends paid by the Banks to Western Alliance. The total amount of dividends which may be paid at any date is generally limited to the retained earnings of each Bank. Dividends paid by the Banks to the

48

Company would be prohibited if the effect thereof would cause the respective Bank’s capital to be reduced below applicable minimum capital requirements.

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, 2005.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls

On July 26, 2006, the Company identified evidence of an employee defalcation pertaining to certain accounts at a branch location of its Bank of Nevada subsidiary. The alleged defalcation involved improper draws and payments on legitimate notes and the creation of fraudulent loans, resulting in fraudulent balances and the potential for legitimate loans with undetected credit problems. This defalcation was facilitated by certain deficiencies in our internal control structure, primarily related to insufficient segregation of duties.

As a result of the foregoing, 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) were not 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.

Changes in Internal Control over Financial Reporting

Subsequent to the discovery of the alleged defalcation, management has implemented staffing changes designed to improve the training of the individuals involved in the daily operations of the Banks. Procedural changes were also implemented to enhance the segregation of duties, which strengthen the review, authorization and reconciliation process so that the probability of employee defalcations occurring in the future is reduced.

Except as discussed above, there have not been any changes in the Company’s internal control over financial reporting which have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
