NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1. Summary of Significant Accounting Policies

Description of Business

F5 Networks, Inc. (the “Company”) provides products and services to help companies manage their Internet Protocol (IP) traffic and file storage infrastructure efficiently and securely. The Company’s application delivery networking products improve the performance, availability and security of applications on Internet-based networks. Internet traffic between network-based applications and clients passes through these devices where the content is inspected to ensure that it is safe and modified as necessary to ensure that it is delivered securely and in a way that optimizes the performance of both the network and the applications. The Company’s storage virtualization products simplify and reduce the cost of managing files and file storage devices, and ensure fast, secure, easy access to files for users and applications. The Company also offers a broad range of services that include consulting, training, maintenance and other technical support services.

Basis of Presentation

The year end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the unaudited consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary for their fair statement in conformity with accounting principles generally accepted in the United States of America. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission. The information included in this Form 10-Q should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations and financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2008.

Revenue Recognition

The Company’s products are integrated with software that is essential to the functionality of the equipment. Accordingly, the Company recognizes revenue in accordance with the guidance provided under Statement of Position (“SOP”) No. 97-2,“Software Revenue Recognition,”and SOP No. 98-9,“Modification of SOP No. 97-2, Software Revenue Recognition, with Respect to Certain Transactions,” Statement of Financial Accounting Standards (“SFAS”) No. 48,“Revenue Recognition When Right of Return Exists,”and SEC Staff Accounting Bulletin (“SAB”) No. 104,“Revenue Recognition.”

The Company sells products through distributors, resellers and directly to end users. The Company recognizes product revenue upon shipment, net of estimated returns, provided that collection is determined to be probable and no significant performance obligations remain. In certain regions where the Company does not have the ability to reasonably estimate returns, the Company defers revenue on sales to its distributors until they have been notified that the distributor has sold the product. Payment terms to domestic customers are generally net 30 days to net 45 days. Payment terms to international customers range from net 30 days to net 90 days based on normal and customary trade practices in the individual markets. The Company may offer extended payment terms to certain customers, in which case, revenue is recognized when payments are due.

Whenever product, training and post-contract customer support (“PCS”) elements are combined into a package with a single “bundled” price, a portion of the sales price is allocated to each element of the bundled package based on their respective fair values as determined when the individual elements are sold separately. The Company determines fair value based on the type of customer and region in which the package is sold. When fair value of all elements sold within a specific region to a certain customer type cannot be established, the Company recognizes revenue on the “residual method” permitted under SOP 98-9 based on the fair value of undelivered elements. Revenues from the sale of products are recognized when the product has been shipped and the customer is obligated to pay for the product. When rights of return are present and the Company cannot estimate returns, it recognizes revenue when such rights of return lapse. Revenues for PCS are recognized on a straight-line basis over the service contract term. PCS includes a limited period of telephone support updates, repair or replacement of any failed product or component that fails during the term of the agreement, bug fixes and rights to upgrades, when and if available.

Consulting services are customarily billed at fixed rates, plus out-of-pocket expenses, and revenues are recognized when the consulting has been completed. Training revenue is recognized when the training has been completed.

In accordance with Emerging Issues Task Force (EITF) 06-03, “How Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement (That Is, Gross versus Net Presentation),” the Company accounts for taxes collected from customers and remitted to governmental authorities on a net basis and excluded from revenues.

Goodwill

Goodwill represents the excess purchase price over the estimated fair value of net assets acquired as of the acquisition date. The Company has adopted the requirements of Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“SFAS No. 142”). SFAS No. 142 requires goodwill to be tested for impairment on an annual basis and between annual tests in certain circumstances, and written down when impaired. Goodwill of $150.2 million was recorded in connection with the acquisition of Acopia Networks, Inc. (“Acopia”) in the fourth quarter of 2007, goodwill of $32.0 million was recorded in connection with the acquisition of Swan Labs, Inc. (“Swan Labs”) in fiscal year 2006, goodwill of $25.5 million was recorded in connection with the acquisition of MagniFire Websystems, Inc. in fiscal year 2004 and goodwill of $24.2 million was recorded in connection with the acquisition of uRoam, Inc. in fiscal year 2003.

The Company performs its annual goodwill impairment test in accordance with SFAS No. 142 during the second fiscal quarter, or whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. The first step of the test identifies whether potential impairment may have occurred, while the second step of the test measures the amount of the impairment, if any. Impairment is recognized when the carrying amount of goodwill exceeds its fair value. For purposes of the annual impairment test, the Company considers its market capitalization on the date of the impairment test since it has only one reporting unit. In March 2009, the Company completed its annual impairment test and concluded that there was no impairment of goodwill. Additionally, as a result of the current economic environment, the Company considered potential impairment indicators at June 30, 2009 and noted no impairment.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with Financial Accounting Standards Board (“FASB”) Statement No. 123(R), “Share-Based Payment” (“FAS 123R”), using the straight-line attribution method for recognizing compensation expense. The Company recognized $12.6 million and $14.8 million of stock-based compensation expense for the three months ended June 30, 2009 and 2008, respectively, and $40.7 million and $45.8 million for the nine months ended June 30, 2009 and 2008, respectively. As of June 30, 2009, there was $42.2 million of total unrecognized stock-based compensation cost, the majority of which will be recognized over the next two years. Going forward, stock-based compensation expenses may increase as the Company issues additional equity-based awards to continue to attract and retain key employees.

The Company issues incentive awards to its employees through stock-based compensation consisting of stock options and restricted stock units (“RSUs”). On August 3, 2009, the Company awarded approximately 1.7 million RSUs to employees and executive officers pursuant to the Company’s annual equity awards program. The value of RSUs is determined using the fair value method, which in this case, is based on the number of shares granted and the quoted price of the Company’s common stock on the date of grant. Alternatively, in determining the fair value of stock options, the Company uses the Black-Scholes option pricing model that employs the following key assumptions. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company does not anticipate declaring dividends in the foreseeable future. Expected volatility is based on the annualized daily historical volatility of the Company’s stock price commensurate with the expected life of the option. Expected term of the option is based on an evaluation of the historical employee stock option exercise behavior, the vesting terms of the respective option and a contractual life of ten years. The Company’s stock price volatility and option lives involve management’s best estimates at that time, both of which impact the fair value of the option calculated under the Black-Scholes methodology and, ultimately, the expense that will be recognized over the life of the option.

FAS 123R also requires the Company to recognize compensation expense for only the portion of options or stock units that are expected to vest. Therefore, the Company applies estimated forfeiture rates that are derived from historical employee termination behavior. Based on historical differences with forfeitures of stock-based awards granted to the Company’s executive officers and Board of Directors versus grants awarded to all other employees, the Company has developed separate forfeiture expectations for these two groups. The Company’s estimated forfeiture rate in the third quarter of fiscal 2009 is 3.2% for grants awarded to the

Company’s executive officers and Board of Directors, and 11.3% for grants awarded to all other employees. If the actual number of forfeitures differs from those estimated by management, additional adjustments to compensation expense may be required in future periods.

Compensation cost recognized for the three and nine month periods ended June 30, 2009 includes: (a) compensation cost for all share-based payments granted prior to, but not yet vested as of July 1, 2005, based on the grant-date fair value estimated in accordance with the original provisions of FASB Statement No. 123, “Accounting for Stock-Based Compensation” and (b) compensation cost for all share-based payments granted or modified subsequent to July 1, 2005, based on the grant-date fair value estimated in accordance with the provisions of FAS 123R.

In August 2008, the Company granted 383,400 RSUs to certain current executive officers. Fifty percent of the aggregate number of RSUs granted at such time vest in equal quarterly increments over two years, until such portion of the grant is fully vested on August 1, 2010. Twenty-five percent of the RSU grant, or a portion thereof, is subject to the Company achieving specified percentage increases in total revenue during the period beginning in the fourth quarter of fiscal year 2008 through the third quarter of fiscal year 2009, relative to the same periods in fiscal years 2007 and 2008 (the “2008 Performance Award”). The executive officers can earn 125% of the 2008 Performance Award if the revenue increase is 20%, 100% of the 2008 Performance Award if the revenue increase is 11%, and 75% of the 2008 Performance Award if the revenue increase is 6%. No portion of the 2008 Performance Award is earned if the revenue increase is less than 6%. The remaining twenty-five percent is subject to the Company achieving specified percentage increases in total revenue during the period beginning in the fourth quarter of fiscal year 2009 through the third quarter of fiscal year 2010, relative to the same periods in fiscal years 2008 and 2009, as will be set by the Compensation Committee of the Company’s Board of Directors.

In August 2007, the Company granted 276,400 RSUs to certain current executive officers. Fifty percent of the aggregate number of RSUs granted at such time vest in equal quarterly increments over two years, until such portion of the grant is fully vested on August 1, 2009. Twenty-five percent of the RSU grant is subject to the Company achieving specified percentage increases in total revenue during the period beginning in the fourth quarter of fiscal year 2007 through the third quarter of fiscal year 2008, relative to the same periods in fiscal years 2006 and 2007. This twenty-five percent was fully earned in fiscal 2008. The remaining twenty-five percent is subject to the Company achieving specified percentage increases in total revenue during the period beginning in the fourth quarter of fiscal year 2008 through the third quarter of fiscal year 2009, relative to the same periods in fiscal years 2007 and 2008, set by the Compensation Committee of the Company’s Board of Directors for the 2008 Performance Award.

The Company recognizes compensation costs for awards with performance conditions when it concludes it is probable that the performance condition will be achieved. The Company reassesses the probability of vesting at each balance sheet date and adjusts compensation costs based on the probability assessment. Performance conditions for these awards were not met in the third fiscal quarter of 2009 and as such, no compensation cost was incurred.

Common Stock Repurchase

On October 22, 2008, the Company announced that its Board of Directors approved a new program to repurchase up to an additional $200 million of the Company’s outstanding common stock. Acquisitions for the share repurchase program will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. The program may be discontinued at any time. As of August 5, 2009, the Company had repurchased and retired 2,869,326 shares at an average price of $24.42 per share in fiscal 2009.

Earnings Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common and dilutive common stock equivalent shares outstanding during the period.

The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share data):


	Three months ended				Nine months ended
	June 30,				June 30,
	2009		2008		2009		2008

Net income	$	22,776	$	19,134	$	63,185	$	54,630

Denominator
Weighted average shares outstanding — basic		78,603		81,096		78,958		83,218
Dilutive effect of common shares from stock options and restricted stock units		1,009		855		1,056		1,090

Weighted average shares outstanding — diluted		79,612		81,951		80,014		84,308

Diluted net income per share	$	0.29	$	0.23	$	0.79	$	0.65

Approximately 0.3 million and 0.7 million of common shares potentially issuable from stock options for the three months ended June 30, 2009 and 2008, respectively, are excluded from the calculation of diluted earnings per share because the exercise price was greater than the average market price of common stock for the respective period. Approximately 0.5 million and 0.6 million of common shares potentially issuable from stock options for the nine months ended June 30, 2009 and 2008, respectively, are excluded from the calculation of diluted earnings per share because the exercise price was greater than the average market price of the Company’s common stock for the respective period.

Comprehensive Income

Comprehensive income includes certain changes in equity that are excluded from net income. Specifically, unrealized gains (losses) on securities and foreign currency translation adjustments are included in accumulated other comprehensive loss. Comprehensive income and its components were as follows (in thousands):


	Three months ended					Nine months ended
	June 30,					June 30,
	2009		2008			2009			2008

Total comprehensive income	$	23,448	$	16,801		$	66,061		$	49,677

Recent Accounting Pronouncements

In December 2007, the FASB issued SFAS No. 160,“Noncontrolling Interests in Consolidated Financial Statements—an amendment of Accounting Research Bulletin No. 51”(“SFAS 160”), which amends Accounting Research Bulletin No. 51 to establish accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 is effective for the Company’s fiscal years beginning October 1, 2009. The Company does not expect the adoption of SFAS 160 to have a material impact on its consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141R,“Business Combinations”(“SFAS 141R”),which establishes principles and requirements for recognizing and measuring identifiable assets and goodwill acquired, liabilities assumed, and any noncontrolling interest in an acquisition, at their fair value as of the acquisition date. SFAS 141R is effective for business combinations for which the acquisition date is on or after October 1, 2009. This standard will change the Company’s accounting treatment for business combinations on a prospective basis.

In April 2008, the FASB issued Staff Position No. 142-3, “Determination of the Useful Life of Intangible Assets”(“FSP 142-3”).FSP 142-3 amends the factors to be considered in assumptions used to determine the useful lives of recognized intangible assets recognized under SFAS No. 142. The new guidance applies to intangible assets with contractual lives that are acquired individually or with a group of assets as well as those assets acquired in a business combination. The new guidance is effective for fiscal years beginning after December 15, 2008 and interim periods. The Company will adopt the statement on October 1, 2009 which is the beginning of its fiscal year 2010. The Company does not expect the adoption of FSP 142-3 to have a significant impact on its consolidated financial position, results of operations or cash flows.

In April 2009, the FASB issued Staff Position No. 157-4,“Determining Fair Value When Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly”(“FSP 157-4”). FSP 157-4 provides guidance on how to determine the fair value of assets and liabilities when the volume and level of activity for the asset/liability has significantly decreased. FSP 157-4 also provides guidance on identifying circumstances that indicate a transaction is not orderly. In addition, FSP 157-4 requires disclosure in interim and annual periods of the inputs and valuation techniques used to measure fair value and a discussion of changes in valuation techniques. The Company adopted FSP 157-4 in the third quarter of fiscal year 2009. The adoption of FSP 157-4 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

In April 2009, the FASB issued Staff Position No. 115-2 and 124-2,“Recognition and Presentation of Other-Than-Temporary Impairment”(“FSP 115-2/124-2”). FSP 115-2/124-2 amends the requirements for the recognition and measurement of other-than-temporary impairments for debt securities by modifying the pre-existing “intent and ability” indicator. Under FSP 115-2/124-2, an other-than-temporary impairment is triggered when there is an intent to sell the security, it is more likely than not that the security will be required to be sold before recovery, or the security is not expected to recover the entire amortized cost basis of the security. Additionally, FSP 115-2/124-2 changes the presentation of an other-than-temporary impairment in the income statement for those impairments involving credit losses. The credit loss component will be recognized in earnings and the remainder of the impairment will be recorded in other comprehensive income. The Company adopted FSP 115-2/124-2 in the third quarter of fiscal year 2009. The adoption of FSP 115-2/124-2 did not impact the Company as there have been no credit losses or other-than-temporary impairment losses on the Company’s available-for-sale securities in prior periods.

In April 2009, the FASB issued Staff Position No. 107-1 and APB 28-1,“Interim Disclosure about Fair Value of Financial Instruments”(“FSP 107-1/APB 28-1”). FSP 107-1/APB 28-1 requires interim disclosures regarding the fair values of financial instruments that are within the scope of FAS 107,“Disclosures about the Fair Value of Financial Instruments.”Additionally, FSP 107-1/APB 28-1 requires disclosure of the methods and significant assumptions used to estimate the fair value of financial instruments on an interim basis as well as changes of the methods and significant assumptions from prior periods. The Company adopted FSP 107-1/APB 28-1 in the third quarter of fiscal year 2009. The adoption of FSP 107-1/APB 28-1 does not change the accounting treatment for these financial instruments.

In May 2009, the FASB issued SFAS No. 165,“Subsequent Events”(“SFAS 165”),which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. It requires the disclosure of the date through which an entity has evaluated subsequent events and the basis for selecting that date, that is, whether that date represents the date the financial statements were issued or were available to be issued. The Company adopted SFAS 165 in the third quarter of fiscal year 2009. The adoption of SFAS 165 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

2. Restructuring Charges

In January 2009, the Company initiated a restructuring plan to reduce its operating expenses which included the consolidation of facilities, accelerated depreciation on tenant improvements and a reduction in workforce in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 146, “Accounting for Costs Associated with Exit or Disposal Activities” (“SFAS 146”). These initiatives are intended to conserve or generate cash in response to the uncertainties associated with the recent deterioration in the global economy. As a result of these initiatives, the Company recorded a restructuring charge of $4.3 million in the second quarter of fiscal 2009. As of June 30, 2009, there was $0.8 million in accrued expenses that will offset futures lease payments through September 2012.

During the six months ended June 30, 2009, the following activity was recorded (in thousands):


	Closure/			Employee
	Consolidation			Severance, Benefits
	of Facilities			and Related Costs			Total
Accrued expenses, January 1, 2009	$	—		$	—		$	—

Accrued expenses, June 30, 2009	$	0.8		$	—		$	0.8

3. Fair Value Measurements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 157, “Fair Value Measurements” (“SFAS 157”), which defines fair value, provides a framework for measuring fair value, and expands the disclosures required for assets and liabilities measured at fair value. SFAS 157 applies to existing accounting pronouncements that require fair value measurements, but it does not require any new fair value measurements. In February 2008, the FASB issued Staff Position No. 157-2, which deferred the effective date of SFAS 157 as it relates to nonfinancial assets and liabilities.

As a basis for categorizing these inputs, SFAS 157 establishes the following hierarchy, which prioritizes the inputs used to measure fair value from market based assumptions to entity specific assumptions:

Level 1:Quoted prices in active markets for identical assets and liabilities at the measurement date.

Level 2:Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3:Unobservable inputs for which there is little or no market data available. These inputs reflect management’s assumptions of what market participants would use in pricing the asset or liability.

The Company adopted the effective portions of SFAS 157 on October 1, 2008, the first day of fiscal 2009. The adoption did not have a material effect on the consolidated financial statements. The Company is currently evaluating the impact of SFAS 157 on its non-financial assets and liabilities, which will be effective at the beginning of fiscal year 2010.

The Company’s financial assets measured at fair value on a recurring basis subject to the disclosure requirements of SFAS 157 at June 30, 2009, were as follows (in thousands):


	Fair Value Measurements at Reporting Date Using
	Quoted Prices in
	Active Markets for		Significant Other		Significant
	Identical Securities		Observable Inputs		Unobservable Inputs		Fair Value at
	(Level 1)		(Level 2)		(Level 3)		June 30, 2009
Cash equivalents	$	12,951	$	—	$	—	$	12,951
Short-term investments
Available for sale securities		—		175,780		—		175,780
Long-term investments
Available for sale securities		—		232,315		—		232,315
Available for sale securities — auction rate securities		—		—		15,601		15,601
Trading securities — auction rate securities		—		—		25,945		25,945
Put option (Note 4)		—		—		1,605		1,605

Total	$	12,951	$	408,095	$	43,151	$	464,197

Due to the auction failures of the Company’s auction rate securities (“ARS”) that began in the second quarter of fiscal 2008, there are still no quoted prices in active markets for identical assets as of June 30, 2009. Therefore, the Company has classified its ARS as level 3 financial assets. The following table provides a reconciliation between the beginning and ending balances of items measured at fair value on a recurring basis in the table above that used significant unobservable inputs (Level 3) (in thousands):


	Significant			Significant
	Unobservable Inputs			Unobservable Inputs
	(Level 3) (1)			(Level 3) (2)
Balance, beginning of period	$	42,740		$	53,350
Total losses realized or unrealized:
Included in earnings		(389	)		(1,605	)
Included in other comprehensive income		411			(3,399	)

Transfers into and/or out of level 3		—			—

Balance, June 30, 2009	$	43,151		$	43,151


Total losses for the period included in earnings (other income, net) or change in net assets attributable to the change in unrealized gains or losses relating to assets still held at June 30, 2009	$	(389	)	$	(1,605	)


(1)		Beginning balance represents the fair value of the Company’s investments in ARS as of March 31, 2009

(2)		Beginning balance represents the fair value (par value) of the Company’s investments in ARS as of February 1, 2008 prior to auction failures

Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 financial assets also include certain investment securities for which there is limited market activity such that the determination of fair value requires significant judgment or estimation. Level 3 investment securities primarily include certain ARS for which there was a decrease in the observation of market pricing. At June 30, 2009, these securities were valued primarily using internal cash flow valuation that incorporates transaction details such as contractual terms, maturity, timing and amount of future cash flows, as well as assumptions about liquidity and credit valuation adjustments of marketplace participants at June 30, 2009.

Total	$	99,556	$	310	$	15,601	$	3,399	$	115,157	$	3,709

The Company invests in securities that are rated investment grade or better. The unrealized losses on investments for the first nine months of fiscal 2009 were primarily caused by reductions in the values of the ARS due to the illiquid markets and were partially offset by unrealized gains related to interest rate decreases.

ARS are variable-rate debt securities. The Company limits its investments in ARS to securities that carry an AAA/A- (or equivalent) rating from recognized rating agencies and limits the amount of credit exposure to any one issuer. At the time of the Company’s initial investment and at the date of this report, all ARS were in compliance with the Company’s investment policy. In the past, the auction process allowed investors to obtain immediate liquidity if so desired by selling the securities at their face amounts. Liquidity for these securities has historically been provided by an auction process that resets interest rates on these investments on average every 7-35 days. However, as has been reported in the financial press, the disruptions in the credit markets adversely affected the auction market for these types of securities.

Beginning in February 2008, auctions failed for approximately $53.4 million in par value of municipal ARS the Company held because sell orders exceeded buy orders. The funds associated with failed auctions will not be accessible until a successful auction occurs or a buyer is found outside the auction process. The Company believes that the appropriate presentation of these securities is long-term investments as reflected in the Company’s consolidated balance sheet at June 30, 2009, as the Company does not believe it will be able to liquidate these securities in the next twelve months.

In October 2008, the Company entered into an agreement (“the Agreement”) with UBS whereby UBS would purchase eligible ARS it sold to the Company prior to February 13, 2008. Under the terms of the Agreement, and at the Company’s discretion, UBS will purchase eligible ARS from the Company at par value (“Put Option”) during the period of June 30, 2010 through July 2, 2012. The Company expects to sell its eligible ARS under the Agreement. However, if the Company does not exercise its rights to sell its eligible ARS under the Agreement before July 2, 2012 this Put Option will expire and UBS will have no further rights or obligations to buy the Company’s ARS. So long as the Company holds its ARS, they will continue to accrue interest as determined by the auction process or the terms of the ARS if the auction process fails. The Company elected to measure the Put Option under the fair value option of SFAS No. 159, and recorded a benefit of approximately $1.6 million pre-tax for the nine months ended June 30, 2009 and recorded a corresponding long term investment. The Company transferred these ARS from available-for-sale to trading investment securities. As a result of accepting the Put Option and reclassifying the ARS from available-for-sale to trading investment securities, the Company recognized an other-than-temporary impairment loss of approximately $1.6 million pre-tax as of June 30, 2009,

reflecting a reversal of the related unrealized loss that was previously recorded in other comprehensive loss. The recording of the fair value of the Put Option and the recognition of the other-than-temporary impairment loss resulted in no impact to the consolidated income statement for the nine months ended June 30, 2009.

5. Inventories

The Company outsources the manufacturing of its pre-configured hardware platforms to contract manufacturers, who assemble each product to the Company’s specifications. As protection against component shortages and to provide replacement parts for its service teams, the Company also stocks limited supplies of certain key product components. The Company reduces inventory to net realizable value based on excess and obsolete inventories determined primarily by historical usage and forecasted demand. Inventories consist of hardware and related component parts and are recorded at the lower of cost or market (as determined by the first-in, first-out method).

Inventories consist of the following (in thousands):


	June 30,		September 30,
	2009		2008
Finished goods	$	9,574	$	6,391
Raw materials		4,016		3,757

	$	13,590	$	10,148

6. Commitments and Contingencies

Guarantees and Product Warranties

In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, resellers, lessors, and parties to other transactions with the Company, with respect to certain matters. The Company has agreed to hold the other party harmless against losses arising from a breach of representations or covenants, or out of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. The Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws contain similar indemnification obligations to the Company’s agents. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement.

The Company offers warranties of one year for hardware for those customers without service contracts, with the option of purchasing additional warranty coverage in yearly increments. The Company accrues for warranty costs as part of its cost of sales based on associated material product costs and technical support labor costs. Accrued warranty costs as of June 30, 2009 and June 30, 2008 were not material.

Purchase Commitments

The Company currently has arrangements with contract manufacturers and other suppliers for the manufacturing of its products. The arrangement with the primary contract manufacturer allows them to procure component inventory on their behalf based on a rolling production forecast provided by the Company. The Company is obligated to the purchase of component inventory that the contract manufacturer procures in accordance with the forecast, unless they give notice of order cancellation in advance of applicable lead times. As of June 30, 2009, the Company was committed to purchase approximately $12.7 million of such inventory during the next quarter.

Legal Proceedings

Derivative Suits.Beginning on or about May 24, 2006, several derivative actions were filed against certain of the Company’s current and former directors and officers. These derivative lawsuits were filed in: (1) the Superior Court of King County, Washington, as In re F5 Networks, Inc. State Court Derivative Litigation (Case No. 06-2-17195-1 SEA), which consolidates Adams v. Amdahl, et al. (Case No. 06-2-17195-1 SEA), Wright v. Amdahl, et al. (Case No. 06-2-19159-5 SEA), and Sommer v. McAdam, et al. (Case No. 06-2-26248-4 SEA) (the “State Court Derivative Litigation”); and (2) in the U.S. District Court for the Western District of Washington, as In re F5 Networks, Inc. Derivative Litigation, Master File No. C06-0794RSL, which consolidates Hutton v. McAdam, et al. (Case No. 06-794RSL), Locals 302 and 612 of the International Union of Operating Engineers-Employers Construction Industry Retirement Trust v. McAdam et al. (Case No. C06-1057RSL), and Easton v. McAdam et al. (Case No. C06-1145RSL) (the “Federal

Court Derivative Litigation”). On August 2, 2007, another derivative lawsuit, Barone v. McAdam et al. (Case No. C07-1200P) was filed in the U.S. District Court for the Western District of Washington. The Barone lawsuit was designated a related case to the Federal Court Derivative Litigation on September 4, 2007. The complaints generally allege that certain of the Company’s current and former directors and officers, including, in general, each of the Company’s current outside directors (other than Deborah L. Bevier and Scott Thompson who joined the Board of Directors in July 2006 and January 2008, respectively) breached their fiduciary duties to the Company by engaging in alleged wrongful conduct concerning the manipulation of certain stock option grant dates. The Company is named solely as a nominal defendant against whom the plaintiffs seek no recovery. The Company’s combined motion to consolidate and stay the State Court Derivative Litigation was granted in a court order dated April 3, 2007. The Company’s motion to dismiss the consolidated federal derivative actions based on plaintiffs’ failure to make demand on the Company’s Board of Directors prior to filing suit was granted in a court order dated August 6, 2007 with leave to amend the allegations in plaintiffs’ complaint. Plaintiffs filed an amended consolidated federal derivative action complaint on September 14, 2007. The Company filed a motion to dismiss the amended complaint based on plaintiff’s failure to make demand on the Company’s Board of Directors prior to filing suit. On July 3, 2008, before ruling on the Company’s pending dismissal motion, the federal court entered an order certifying certain issues of Washington state law to the Washington Supreme Court for resolution. The hearing in the Washington Supreme Court was held on March 24, 2009. On May 21, 2009, the Washington Supreme Court issued its opinion on the certified issues submitted by the federal court. The Company’s dismissal motion remains pending before the federal court and the Company intends to continue to vigorously pursue dismissal of the derivative actions.

SEC and Department of Justice Inquiries.In May 2006, the Company received notice from both the SEC and the Department of Justice that they were conducting informal inquiries into the Company’s historical stock option practices, and have fully cooperated with both agencies. Considerable legal and accounting expenses related to the Company’s historical stock option practices have been incurred to date. The Company may in the future be subject to additional regulatory proceedings or actions arising in relation to the Company’s historical stock option practices and the restatement of the Company’s prior period financial statements. Although regulatory proceedings are subject to inherent uncertainties, the Company does not believe the results of any pending actions will, individually or in the aggregate, have a material adverse impact on the Company’s consolidated financial position or results of operations.

The Company is not aware of any additional pending legal proceedings that, individually or in the aggregate, would have a material adverse effect on the Company’s business, operating results, or financial condition. The Company may in the future be party to litigation arising in the ordinary course of business, including claims that we allegedly infringe upon third-party trademarks or other intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

7. Income Taxes

The effective tax rate was 33.7% and 38.1% for the three months ended June 30, 2009 and 2008, respectively, and 29.7% and 38.7% for the nine months ended June 30, 2009 and 2008, respectively. Our effective tax rates for the aforementioned periods in fiscal 2009 are lower than the respective periods in fiscal 2008 due to the reinstatement of the federal research and development tax credit, the deduction for tax purposes of compensation related to equity awards in a major foreign tax jurisdiction, and “true-up” items between our fiscal year 2008 provision and actual amounts used when filing our fiscal year 2008 income tax returns during fiscal 2009.

During the three months ended June 30, 2009, the Company increased its liability for unrecognized tax benefits by $734,000, which is an increase to the Company’s uncertain tax positions as disclosed in Note 5 of the 2008 Annual Report and on Form 10-K. At June 30, 2009 the Company has classified approximately $4.6 million of unrecognized tax liabilities as a non-current liability.

Due to an ongoing audit by the Internal Revenue Service it is reasonably possible that the reserves may change within the next 12 months.

The Company recognizes interest and, if applicable, penalties for any uncertain tax positions. This interest and penalty expense will be a component of income tax expense. At the adoption of FASB Interpretation No. 48,“Accounting for Uncertainty in Income Taxes — An Interpretation of FASB Statement No. 109”(“FIN 48”), the Company had not accrued any interest or penalties on unrecognized tax benefits. In the three months ended June 30, 2009, the Company accrued an immaterial amount of interest expense related to its liability for unrecognized tax benefits under FIN 48. All unrecognized tax benefits, if recognized, would affect the effective tax rate.

The Company and its subsidiaries are subject to U.S. federal income tax as well as the income tax of multiple state and foreign jurisdictions. The Company has concluded all U.S. federal income tax matters for fiscal years through September 30, 2005 and is currently under examination by the Internal Revenue Service for the fiscal year ending September 30, 2007. Major jurisdictions where there are wholly owned subsidiaries of F5 Networks, Inc. which require income tax filings include the United Kingdom, Japan, Australia and Germany. Periods open for review by local taxing authorities are fiscal years 2006, 2003, 2004 and 2003 for the United Kingdom, Japan, Australia and Germany, respectively. Within the next four fiscal quarters, the statute of limitations will begin to close on the fiscal years ended 2005 and 2006 tax returns filed in various states and the fiscal year ended 2006 federal income tax return.

8. Geographic Sales and Significant Customers

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company is organized as, and operated in, one reportable segment: the development, marketing and sale of application delivery networking products that optimize the security, performance & availability of network applications, servers and storage systems. The Company manages its business based on four geographic regions: the Americas (primarily the United States); Europe, the Middle East, and Africa (EMEA); Japan; and the Asia Pacific region (APAC). The Company’s chief operating decision-making group reviews financial information presented on a consolidated basis accompanied by information about revenues by geographic region. The Company’s foreign offices conduct sales, marketing and support activities. Management evaluates performance based primarily on revenues in the geographic locations in which the Company operates. Revenues are attributed by geographic location based on the location of the customer. The Company’s assets are primarily located in the United States and not allocated to any specific region. Therefore, geographic information is presented only for net product revenue.

The following presents revenues by geographic region (in thousands):

9. Subsequent Events

The Company has performed an evaluation of subsequent events through August 7, 2009, which is the date the financial statements were issued.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 and Section 27A of the Securities Act of 1933. These statements include, but are not limited to, statements about our plans, objectives, expectations, strategies, intentions or other characterizations of future events or circumstances and are generally identified by the words “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and similar expressions. These forward-looking statements are based on current information and expectations and are subject to a number of risks and uncertainties. Our actual results could differ materially from those expressed or implied by these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed under “Item 1A. Risk Factors” herein and in other documents we file from time to time with the Securities and Exchange Commission. We assume no obligation to revise or update any such forward-looking statements.

Overview

We are a global provider of appliances consisting of software and hardware and services that help companies efficiently and securely manage the delivery, optimization and security of application and data traffic on Internet-based networks, and to optimize the performance and utilization of data storage infrastructure and other network resources. We market and sell our products primarily through multiple indirect sales channels in the Americas (primarily the United States); Europe, the Middle East, and Africa (EMEA); Japan (Japan); and the Asia Pacific region (APAC). Enterprise customers (Fortune 1000 or Business Week Global 1000 companies) in technology, telecommunications, financial services, transportation, and manufacturing industries, along with government customers, continue to make up the largest percentage of our customer base.

Our management monitors and analyzes a number of key performance indicators in order to manage our business and evaluate our financial and operating performance. Those indicators include:

•

Revenues.The majority of our revenues are derived from sales of our Application Delivery Networking (“ADN”) products; BIG-IP Local Traffic Manager, BIG-IP Global Traffic Manager, BIG-IP ISP Traffic Manager, TrafficShield Application Firewall, WANJet, and WebAccelerator; FirePass SSL VPN servers; and our ARX file virtualization products. We also derive revenues from the sales of services including annual maintenance contracts, training and consulting services. We carefully monitor the sales mix of our revenues within each reporting period. We believe customer acceptance rates of our new products and feature enhancements are key indicators of future trends. We also consider overall revenue concentration by customer and by geographic region as additional indicators of current and future trends.

•

Cost of revenues and gross margins.We strive to control our cost of revenues and thereby maintain our gross margins. Significant items impacting cost of revenues are hardware costs paid to our contract manufacturers, third-party software license fees, amortization of developed technology and personnel and overhead expenses. Our margins have remained relatively stable over the past two years. However, factors such as sales price, product mix, inventory obsolescence, returns, component price increases and warranty costs could significantly impact our gross margins from quarter to quarter and represent significant indicators we monitor on a regular basis.

•

Operating expenses.Operating expenses are substantially driven by personnel and related overhead expenses. Existing headcount and future hiring plans are the predominant factors in analyzing and forecasting future operating expense trends. Other significant operating expenses that we monitor include marketing and promotions, travel, professional fees, computer costs related to the development of new products, facilities and depreciation expenses.

•

Liquidity and cash flows.Our financial condition remains strong with significant cash and investments and no long term debt. The increase in cash and investments for the first nine months of fiscal year 2009 was primarily due to net income from operations, with operating activities providing cash of $143.4 million. This increase was partially offset by $63.3 million of cash used to repurchase outstanding common stock under our stock repurchase program in the first three quarters of fiscal 2009. Going forward, we believe the primary driver of cash flows will be net income from operations. Capital expenditures for the first nine months of fiscal year 2009 were comprised primarily of information technology infrastructure and equipment to support the growth of our core business activities. We will continue to evaluate possible acquisitions of, or investments in businesses, products, or technologies that we believe are strategic, which may require the use of cash.

•

Balance sheet.We view cash, short-term and long-term investments, deferred revenue, accounts receivable balances and day’s sales outstanding as important indicators of our financial health. Deferred revenues continued to increase due to the growth in the amount of annual maintenance contracts purchased on new products and maintenance renewal contracts related to our existing product installation base. Our day’s sales outstanding for the third quarter of fiscal year 2009 was 52. We expect to maintain this metric in the mid 50-day range going forward.

Summary of Critical Accounting Policies and Estimates

The preparation of our financial condition and results of operations requires us to make judgments and estimates that may have a significant impact upon our financial results. We believe that, of our significant accounting policies, the following require estimates and assumptions that require complex, subjective judgments by management, which can materially impact reported results: revenue recognition; reserve for doubtful accounts; reserve for product returns; reserve for warranties; accounting for income taxes; stock-based compensation; investments; goodwill impairment; and the fair value measurements of financial assets and liabilities. None of

these accounting policies and estimates have significantly changed since our annual report on Form 10-K for the year ended September 30, 2008 (“Form 10-K”), except for the accounting for fair value measurements of financial assets and liabilities and the related disclosures, which is further discussed in Item 1, Note 3 of Part I of this Form 10-Q. Critical accounting policies and estimates are more fully described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Form 10-K. Actual results may differ from these estimates under different assumptions or conditions.

Results of Operations

The following discussion and analysis should be read in conjunction with our consolidated financial statements, related notes and risk factors included elsewhere in this Quarterly Report on Form 10-Q.

Net revenues.Total net revenues decreased 4.4% for the three months ended June 30, 2009 from the same period in the prior year, and remained consistent with the nine months ended June 30, 2009 from the same period in the prior year. The decrease in overall revenue for the three months ended June 30, 2009 was primarily due to a reduction in the volume of product sales in response to the slowing economic environment, partially offset by an increase in service revenue as a result of our increased installed base of products. International revenues were 44.2% and 45.1% of total net revenues for the three and nine months ended June 30, 2009, respectively, compared to 41.8% and 43.4% for the same periods in the prior year, respectively. We expect international sales will continue to represent a significant portion of net revenues, although we cannot provide assurance that international revenues as a percentage of net revenues will remain at current levels.

Net product revenues decreased 16.7% and 11.7% for the three and nine months ended June 30, 2009, respectively, from the same periods in the prior year. The decrease in net product revenues for the three months ended June 30, 2009 was primarily due to a $17.1 million reduction in the volume of products sales of our ADN products from the same period in the prior year. The decrease in net product revenues for the nine months ended June 30, 2009 was primarily due to a $28.1 million reduction in the volume of sales of our ADN products and a $5.8 million reduction in the sales of our ARX file virtualization products, as compared to same period in the prior year. Sales of our ADN products represented 93.9% of product revenues for both the three and nine months ended June 30, 2009, compared to 93.1% and 91.3% for the same periods in the prior year, respectively.

Net service revenues increased 23.3% and 27.2% for the three and nine months ended June 30, 2009, respectively, from the same periods in the prior year. The increase in net service revenues was primarily due to increases in the purchase or renewal of maintenance contracts driven by additions to our installed base of products.

Avnet Technology Solutions, one of our worldwide distributors, accounted for 15.2% and 16.0% of our total net revenue for the three and nine months ended June 30, 2009, respectively. Avnet Technology Solutions and Ingram Micro Inc., two of our worldwide distributors, accounted for 14.2% and 10.8% of our total net revenue for the three months ended June 30, 2008, respectively. Avnet Technology Solutions and Ingram Micro Inc. accounted for 13.4% and 10.6% of our total net revenue for the nine months ended June 30, 2008, respectively. Avnet Technology Solutions accounted for 10.2% of our accounts receivable as of June 30, 2009. No other distributors accounted for more than 10% of total net revenue or receivables.

Cost of net product revenues. Cost of net product revenues consist of finished products purchased from our contract manufacturers, manufacturing overhead, freight, warranty, provisions for excess and obsolete inventory and amortization expenses in connection with developed technology from acquisitions. Cost of net product revenues decreased 16.1% and 6.5% for the three and nine months ended June 30, 2009, respectively, as compared to the same periods in the prior year. The decrease in cost of net product revenues is primarily due to a reduction in the volume of product sales.

Cost of net service revenues. Cost of net service revenues consist of the salaries and related benefits of our professional services staff, travel, facilities and depreciation expenses. For the three and nine months ended June 30, 2009, cost of net service revenues as a percentage of net service revenues decreased to 18.7% and 19.6%, respectively, compared to 23.7% and 24.2% for the same periods in the prior year, respectively, primarily due to the scalability of our existing customer support infrastructure and increased revenue from maintenance contracts. Professional services headcount at the end of June 2009 remained consistent with the end of June 2008 at 316. In addition, cost of net service revenues includes stock-based compensation expense of $1.1 million and $3.4 million for the three and nine months ended June 30, 2009, respectively, compared to $1.0 million and $2.9 million for the same periods in the prior year, respectively.

Sales and marketing.Sales and marketing expenses consist of salaries, commissions and related benefits of our sales and marketing staff, the costs of our marketing programs, including public relations, advertising and trade shows, travel, facilities and depreciation expenses. Sales and marketing expenses decreased 8.4% and 5.6% for the three and nine months ended June 30, 2009, respectively, from the comparable periods in the prior year. The decrease in sales and marketing expense was primarily due to cost reduction initiatives we implemented in response to the slowing economic environment and a $2.0 million decrease in commissions expense corresponding to the decrease in revenue for the three months ended June 30, 2009, compared to the same period in the prior year. Sales and marketing headcount at the end of June 2009 decreased to 676 from 709 at the end of June 2008. The decrease in headcount was primarily related to a reduction in workforce that took place in the second fiscal quarter as part of our restructuring program. Sales and marketing expense included stock-based compensation expense of $5.1 million and $16.5 million for the three and nine months ended June 30, 2009, respectively, compared to $5.8 million and $18.4 million for the same periods in the prior year.

Research and development. Research and development expenses consist of the salaries and related benefits for our product development personnel, prototype materials and other expenses related to the development of new and improved products, facilities and depreciation expenses. Research and development expenses decreased 4.6% for the three months ended June 30, 2009 from the comparable period in the prior year and increased 1.5% for the nine months ended June 30, 2009 from the comparable period in the prior year. The increase in research and development expense for the first nine months of fiscal 2009 was primarily due to an increase

of $1.7 million in personnel costs compared to the same period in the prior year. Research and development headcount at the end of June 2009 decreased to 429 from 453 at the end of June 2008. The decrease in headcount was primarily related to the reduction in workforce that took place in the second fiscal quarter of 2009. Research and development expense included stock-based compensation expense of $3.8 million and $12.2 million for the three and nine months ended June 30, 2009, compared to $4.1 million and $12.2 million for the same periods in the prior year. We expect research and development expenses to remain consistent as a percentage of net revenue in the foreseeable future.

General and administrative. General and administrative expenses consist of the salaries, benefits and related costs of our executive, finance, information technology, human resource and legal personnel, third-party professional service fees, bad debt charges, facilities and depreciation expenses. General and administrative expenses decreased 5.2% and 1.8% for the three and nine months ended June 30, 2009, respectively, from the comparable periods in the prior year. The decrease in general and administrative expenses for the three and nine months ended June 30, 2009 as compared to the same periods in the prior year was primarily due to a decrease in stock-based compensation expense of $1.4 million and $3.7 million, respectively. Stock-based compensation expense was $2.4 million and $8.3 million for the three and nine months ended June 30, 2009, compared to $3.8 million and $12.0 million for the same periods in the prior year. General and administrative headcount at the end of June 2009 decreased to 183 from 188 at the end of June 2008. The decrease in headcount was primarily related to a reduction in workforce that took place in the second fiscal quarter as part of our restructuring program.

Restructuring.Beginning in the second quarter of fiscal 2009 we implemented a comprehensive restructuring program as part of an overall initiative to reduce certain operating expenses. Restructuring actions included the consolidation of facilities, accelerated depreciation on tenant improvements and a reduction in workforce. In the second quarter of fiscal 2009, we recorded restructuring expenses of $4.3 million, which included a $2.1 million charge for severance and related costs and a $2.2 million charge for the exit of certain offices worldwide. We had $0.8 million of accrued restructuring cost at June 30, 2009, which we expect to offset future rent expenses through September 2012.

Other income, net.Other income, net, consists of interest income and foreign currency transaction gains and losses. Other income, net, decreased 18.5% and 47.9% for the three and nine months ended June 30, 2009, respectively, compared to the same periods in the prior year. The decrease in other income, net for the three months ended June 30, 2009 compared to the same period in the prior year was primarily due to decreased interest income of $1.4 million, partially offset by foreign currency transaction gains of $0.9 million. The decrease in other income, net for the nine months ended June 30, 2009 compared to the same period in the prior year was primarily due to decreased interest income of $6.2 million and decreased foreign currency transaction gains of $1.0 million. The decrease in interest income for both periods was primarily due to a decline in interest rates in the first three quarters of 2009.

Provision for Income taxes. We recorded a 33.7% provision for income taxes for the three month period ended June 30, 2009. As of June 30, 2009, we estimate our effective tax rate will be 31.2% for the fiscal year ended September 30, 2009. At June 30, 2009, we did not have a valuation allowance on any of our deferred tax assets in any of the jurisdictions in which we operate because we believe that these assets are more likely than not to be realized. In making this determination we have considered projected future taxable income and ongoing prudent and feasible tax planning strategies in assessing the appropriateness of a valuation allowance. Our net deferred tax assets at June 30, 2009 and June 30, 2008 were $49.8 million and $44.5 million, respectively. Our worldwide effective tax rate may fluctuate based on a number of factors including variations in projected taxable income in the various geographic locations in which we operate, changes in the valuation of our net deferred tax assets, resolution of potential exposures, tax positions

taken on tax returns filed in the various geographic locations in which we operate, and the introduction of new accounting standards or changes in tax laws or interpretations thereof in the various geographic locations in which we operate. In addition, on May 4, 2009 U.S. President Barack Obama proposed significant changes to the U.S. international tax laws that would limit U.S. deductions for expenses related to un-repatriated foreign-source income and modify the U.S. foreign tax credit and “check-the-box” rules. We cannot determine whether these proposals will be enacted into law or what, if any, changes may be made to such proposals prior to their being enacted into law. If the U.S. tax laws change in a manner that increases our tax obligation, our results could suffer.

We have recorded liabilities to address potential tax exposures related to business and income tax positions we have taken that could be challenged by taxing authorities. The ultimate resolution of these potential exposures may be greater or less than the liabilities recorded which could result in an adjustment to our future tax expense.

Liquidity and Capital Resources

Cash and cash equivalents, short-term investments and long-term investments totaled $537.9 million as of June 30, 2009 compared to $451.3 million as of September 30, 2008, representing an increase of $86.6 million. The increase was primarily due to cash provided by operating activities of $143.4 million for the nine months ended June 30, 2009 compared to $134.7 million for the same period in the prior year, which was partially offset by $63.3 million of additional cash required for the repurchase of outstanding common stock under our stock repurchase program. The increase in cash flow from operations for the first nine months of fiscal year 2009 resulted from increased net income combined with changes in operating assets and liabilities, as adjusted for various non-cash items including stock-based compensation, depreciation and amortization charges. Based on our current operating and capital expenditure forecasts, we believe that our existing cash and investment balances, excluding auction rate securities (“ARS”), together with cash generated from operations should be sufficient to meet our operating requirements for the foreseeable future.

At June 30, 2009, we held $46.6 million (par value) of long-term investments comprised of tax-exempt ARS, which are variable-rate debt securities and have a long-term maturity with the interest being reset through Dutch auctions that are typically held every 7, 28 or 35 days. The securities have historically traded at par and are callable at par at the option of the issuer. Interest is typically paid at the end of each auction period or semi-annually. We limit our investments in ARS to securities that carry a AAA/A- (or equivalent) rating from recognized rating agencies and limit the amount of credit exposure to any one issuer. At the time of initial investment and at the date of this Quarterly Report on Form 10-Q, all of our ARS were in compliance with our investment policy.

Beginning in February 2008, auctions failed for approximately $53.4 million in par value of municipal ARS we held because sell orders exceeded buy orders. When these auctions failed to clear, higher interest rates for those securities went into effect. However, the funds associated with these failed auctions will not be accessible until the issuer calls the security, a successful auction occurs, a buyer is found outside of the auction process or the security matures. The underlying assets of the municipal ARS we hold, including the securities for which auctions have failed, are generally student loans which are guaranteed by the U.S. government.

We have no reason to believe that any of the underlying issuers of our ARS are presently at risk of default. Through June 30, 2009, we have continued to receive interest payments on the ARS in accordance with their terms. We believe we will be able to liquidate our investments without significant loss primarily due to the government guarantee of the underlying securities. However, due to recent changes and uncertainty in the ARS market, we believe these investments may remain illiquid for longer than twelve months and as a result, we have classified these investments as long-term as of June 30, 2009.

In October 2008, we entered into an agreement (“the Agreement”) with UBS whereby UBS would purchase eligible ARS it sold to us prior to February 13, 2008. Under the terms of the Agreement, and at our discretion, UBS will purchase eligible ARS from us at par value (“Put Option”) during the period of June 30, 2010 through July 2, 2012. We expect to sell our eligible ARS under the Agreement. However, if we do not exercise our rights to sell our eligible ARS under the Agreement before July 2, 2012 the Put Option will expire and UBS will have no further rights or obligations to buy our ARS. So long as we hold our ARS, they will continue to accrue interest as determined by the auction process or the terms of the ARS if the auction process fails. We elected to measure the Put Option under the fair value option of SFAS No. 159, and recorded a benefit of approximately $1.6 million pre-tax for the nine months ended June 30, 2009, and recorded a corresponding long term investment. We transferred these ARS from available-for-sale to trading investment securities. As a result of accepting the Put Option and reclassifying the ARS from available-for-sale to trading investment securities, we recognized an other-than-temporary impairment loss of approximately $1.6 million pre-tax as of June 30, 2009, reflecting a reversal of the related unrealized loss that was previously recorded in other comprehensive loss. The recording of the fair value of the Put Option and the recognition of the other-than-temporary impairment loss resulted in no impact to the consolidated income statement for the nine months ended June 30, 2009.

Cash used in investing activities was $82.5 million for the nine months ended June 30, 2009 compared to cash provided by investing activities of $54.8 million for the same period in the prior year. Investing activities include purchases and maturities of available-for-sale securities, capital expenditures and changes in restricted cash requirements. The amount of cash used in investing activities for the first nine months of fiscal year 2009 was primarily due to the purchase of investments and capital expenditures related to maintaining our operations worldwide partially offset by the maturity of investments.

Cash used in financing activities for the nine months ended June 30, 2009 was $50.7 million compared to $133.6 million for the same period in the prior year. Our financing activities for the nine months ended June 30, 2009 consisted primarily of cash required for the repurchase of outstanding common stock under our stock repurchase program of $63.3 million, partially offset by cash received from the exercise of employee stock options and warrants of $15.3 million.

Obligations and Commitments

As of June 30, 2009, our principal commitments consisted of obligations outstanding under operating leases. We lease our facilities under operating leases that expire at various dates through 2018. There have been no material changes in our principal lease commitments compared to those discussed in the Form 10-K. In connection with the lease agreement for our corporate headquarters, we established a restricted escrow account collateralized by a certificate of deposit that has been included on our balance sheet as a component of restricted cash. The total amount required in escrow reduces at various dates as set forth by the lease agreement. The amount required in escrow at June 30, 2009 was $2.4 million as set forth by the lease agreement.

We outsource the manufacturing of our pre-configured hardware platforms to contract manufacturers who assemble each product to our specifications. Our agreement with our largest contract manufacturer allows them to procure component inventory on our behalf based upon a rolling production forecast. We are contractually obligated to purchase the component inventory in accordance with the forecast, unless we give notice of order cancellation in advance of applicable lead times. As of June 30, 2009, we were committed to purchase approximately $12.7 million of such inventory during the next quarter.

Recent Accounting Pronouncements

The anticipated impact of recent accounting pronouncements is discussed in Note 1 to the accompanying Notes to Consolidated Financial Statements of this Quarterly Report on Form 10-Q.

Risk Factors that May Affect Future Results

This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks and uncertainties. Our business, operating results, financial performance and share price may be materially adversely affected by a number of factors, including but not limited to the following risk factors, any one of which could cause actual results to vary materially from anticipated results or from those expressed in any forward-looking statements made by us in this Quarterly Report on Form 10-Q or in other reports, press releases or other statements issued from time to time. Additional factors that may cause such a difference are set forth elsewhere in this Quarterly Report on Form 10-Q.

Our success depends on our timely development of new products and features, market acceptance of new product offerings and proper management of the timing of the life cycle of our products

The application delivery networking and file virtualization markets are characterized by rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. Our continued success depends on our ability to identify and develop new products and new features for our existing products to meet the demands of these changes, and the acceptance of those products and features by our existing and target customers. If we are unable to identify, develop and deploy new products and new product features on a timely basis, our business and results of operations may be harmed.

The current life cycle of our products is typically 12 to 24 months. The introduction of new products or product enhancements may shorten the life cycle of our existing products, or replace sales of some of our current products, thereby offsetting the benefit of even a successful product introduction, and may cause customers to defer purchasing our existing products in anticipation of the new products. This could harm our operating results by decreasing sales, increasing our inventory levels of older products and exposing us to greater risk of product obsolescence. We have also experienced, and may in the future experience, delays in developing and releasing new products and product enhancements. This has led to, and may in the future lead to, delayed sales, increased expenses and lower quarterly revenue than anticipated. Also, in the development of our products, we have experienced delays in the prototyping

of our products, which in turn has led to delays in product introductions. In addition, complexity and difficulties in managing product transitions at the end-of-life stage of a product can create excess inventory of components associated with the outgoing product that can lead to increased expenses. Any or all of the above problems could materially harm our business and results of operations.

Our success depends on sales and continued innovation of our Application Delivery Networking product lines

For the fiscal year ended September 30, 2008 and the three months ended June 30, 2009, we derived approximately 92.0% and 93.9%, respectively, of our net product revenues, or approximately 64.1% and 56.7%, respectively, of our total net revenues, from sales of our Application Delivery Networking (“ADN”) product lines. We continue to expect to derive a significant portion of our net revenues from sales of our ADN products in the future. Implementation of our strategy depends upon these products being able to solve critical network availability and performance problems of our customers. If our ADN products are unable to solve these problems for our customers or if we are unable to sustain the high levels of innovation in our ADN product feature set needed to maintain leadership in what will continue to be a competitive market environment, our business and results of operations will be harmed.

We may not be able to compete effectively in the emerging application delivery networking and file virtualization markets

The markets we serve are new, rapidly evolving and highly competitive, and we expect competition to persist and intensify in the future. Our principal competitors in the application delivery networking market include Cisco, Nortel, Citrix, and Radware. In the adjacent WAN Optimization market, we compete with Riverbed, Juniper, Blue Coat Systems, Cisco and Citrix. In the file virtualization market, we compete with EMC, Net-App, Brocade and Cisco. We expect to continue to face additional competition as new participants enter our markets. As we continue to expand globally, we may see new competitors in different geographic regions. In addition, larger companies with significant resources, brand recognition, and sales channels may form alliances with or acquire competing application delivery networking solutions from other companies and emerge as significant competitors. Potential competitors may bundle their products or incorporate an Internet traffic management or security component into existing products in a manner that discourages users from purchasing our products. Any of these circumstances may limit our opportunities for growth and negatively impact our financial performance.

Our quarterly and annual operating results are inherently unpredictable and may cause our stock price to fluctuate

Our quarterly and annual operating results have varied significantly in the past and will vary significantly in the future, which makes it difficult for us to predict our future operating results. In particular, we anticipate that the size of customer orders may increase as we continue to focus on larger business accounts. A delay in the recognition of revenue, even from just one account, may have a significant negative impact on our results of operations for a given period. In the past, a majority of our sales have been realized near the end of a quarter. Accordingly, a delay in an anticipated sale past the end of a particular quarter may negatively impact our results of operations for that quarter, or in some cases, that fiscal year. Additionally, we have exposure to the credit risks of some of our customers and sub-tenants. Although we have programs in place that are designed to monitor and mitigate the associated risk, there can be no assurance that such programs will be effective in reducing our credit risks adequately. We monitor individual payment capability in granting credit arrangements, seek to limit the total credit to amounts we believe our customers can pay and maintain reserves we believe are adequate to cover exposure for potential losses. If there is a deterioration of a sub-tenant’s or a major customer’s creditworthiness or actual defaults are higher than expected, future losses, if incurred, could harm our business and have a material adverse effect on our operating results.

Further, our operating results may be below the expectations of securities analysts and investors in future quarters or years. Our failure to meet these expectations will likely harm the market price of our common stock. Such a decline could occur, and has occurred in the past, even when we have met our publicly stated revenue and/or earnings guidance.

The average selling price of our products may decrease and our costs may increase, which may negatively impact gross profits

It is possible that the average selling prices of our products will decrease in the future in response to competitive pricing pressures, increased sales discounts, new product introductions by us or our competitors or other factors. Therefore, in order to maintain our gross profits, we must develop and introduce new products and product enhancements on a timely basis and continually reduce our product costs. Our failure to do so will cause our net revenue and gross profits to decline, which will harm our business and results of operations. In addition, we may experience substantial period-to-period fluctuations in future operating results due to the erosion of our average selling prices.

It is difficult to predict our future operating results because we have an unpredictable sales cycle

Our products have a lengthy sales cycle and the timing of our revenue is difficult to predict. Historically, our sales cycle has ranged from approximately two to three months and has tended to lengthen as we have increasingly focused our sales efforts on the enterprise market. Also, as our distribution strategy has evolved into more of a channel model, utilizing value-added resellers, distributors and systems integrators, the level of variability in the length of sales cycle across transactions has increased and made it more difficult to predict the timing of many of our sales transactions. Sales of our products require us to educate potential customers in their use and benefits. Sales of our products are subject to delays from the lengthy internal budgeting, approval and competitive evaluation processes that large corporations and governmental entities may require. For example, customers frequently begin by evaluating our products on a limited basis and devote time and resources to testing our products before they decide whether or not to purchase. Customers may also defer orders as a result of anticipated releases of new products or enhancements by our competitors or us. As a result, our products have an unpredictable sales cycle that contributes to the uncertainty of our future operating results.

Our business may be harmed if our contract manufacturers are not able to provide us with adequate supplies of our products or if a single source of hardware assembly is lost or impaired

We outsource the manufacturing of our hardware platforms to third party contract manufacturers who assemble these hardware platforms to our specifications. We have experienced minor delays in shipments from contract manufacturers in the past. However, if we experience major delays in the future or other problems, such as inferior quality and insufficient quantity of product, any one or a combination of these factors may harm our business and results of operations. The inability of our contract manufacturers to provide us with adequate supplies of our products or the loss of one or more of our contract manufacturers may cause a delay in our ability to fulfill orders while we obtain a replacement manufacturer and may harm our business and results of operations. In particular, we currently subcontract manufacturing of our application delivery networking products to a single contract manufacturer with whom we do not have a long-term contract. If our arrangement with this single source of hardware assembly was terminated or otherwise impaired, and we were not able to engage another contract manufacturer in a timely manner, our business, financial condition and results of operation could be adversely affected.

If the demand for our products grows, we will need to increase our raw material and component purchases, contract manufacturing capacity and internal test and quality control functions. Any disruptions in product flow may limit our revenue, may harm our competitive position and may result in additional costs or cancellation of orders by our customers.

Our business could suffer if there are any interruptions or delays in the supply of hardware components from our third-party sources

We currently purchase several hardware components used in the assembly of our products from a number of single or limited sources. Lead times for these components vary significantly. The unavailability of suitable components, any interruption or delay in the supply of any of these hardware components or the inability to procure a similar component from alternate sources at acceptable prices within a reasonable time, may delay assembly and sales of our products and, hence, our revenues, and may harm our business and results of operations.

We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets

Our products are subject to U.S. export controls and may be exported outside the U.S. only with the required level of export license or through an export license exception because we incorporate encryption technology into our products. In addition, various countries regulate the import of certain encryption technology and have enacted laws that could limit our ability to distribute our products or our customers’ ability to implement our products in those countries. Changes in our products or changes in export and import regulations may create delays in the introduction of our products in international markets, prevent our customers with international operations from deploying our products throughout their global systems or, in some cases, prevent the export or import of our products to certain countries altogether. Any change in export or import regulations or related legislation, shift in approach to the enforcement or scope of existing regulations or change in the countries, persons or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. For example, we will need to comply with Waste Electrical and Electronic Equipment Directive laws, which are being adopted by certain European Economic Area countries on a country-by-country basis. Failure to comply with these and similar laws on a timely basis, or at all, could have a material adverse effect on our business, operating results and financial condition. Any decreased use of our products or limitation on our ability to export or sell our products would likely adversely affect our business, operating results and financial condition.

We may not be able to adequately protect our intellectual property and our products may infringe on the intellectual property rights of third parties

We rely on a combination of patent, copyright, trademark and trade secret laws, and restrictions on disclosure of confidential and proprietary information to protect our intellectual property rights. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our products is difficult, and we cannot be certain that the steps we have taken will prevent misappropriation of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In the ordinary course of our business, we are involved in disputes and licensing discussions with others regarding their claimed proprietary rights and cannot assure you that we will always successfully defend ourselves against such claims. If we are found to infringe the proprietary rights of others, or if we otherwise settle such claims, we could be compelled to pay damages or royalties and either obtain a license to those intellectual property rights or alter our products so that they no longer infringe upon such proprietary rights. Any license could be very expensive to obtain or may not be available at all. Similarly, changing our products or processes to avoid infringing upon the rights of others may be costly or impractical. In addition, we have initiated, and may in the future initiate, claims or litigation against third parties for infringement of our proprietary rights, or to determine the scope and validity of our proprietary rights or those of our competitors. Any of these claims, whether claims that we are infringing the proprietary rights of others, or vice versa, with or without merit, may be time-consuming, result in costly litigation and diversion of technical and management personnel or require us to cease using infringing technology, develop non-infringing technology or enter into royalty or licensing agreements. Further, our license agreements typically require us to indemnify our customers, distributors and resellers for infringement actions related to our technology, which could cause us to become involved in infringement claims made against our customers, distributors or resellers. Any of the above-described circumstances relating to intellectual property rights disputes could result in our business and results of operations being harmed.

Many of our products include intellectual property licensed from third parties. In the future, it may be necessary to renew licenses for third party intellectual property or obtain new licenses for other technology. These third party licenses may not be available to us on acceptable terms, if at all. The inability to obtain certain licenses, or litigation regarding the interpretation or enforcement of license rights and related intellectual property issues, could have a material adverse effect on our business, operating results and financial condition. Furthermore, we license some third party intellectual property on a non-exclusive basis and this may limit our ability to protect our intellectual property rights in our products.

We may not be able to sustain or develop new distribution relationships and a reduction or delay in sales to significant distribution partners could hurt our business

We sell our products and services through multiple distribution channels in the United States and internationally, including leading industry distributors, value-added resellers, systems integrators, and other indirect channel partners. We have a limited number of agreements with companies in these channels, and we may not be able to increase our number of distribution relationships or maintain our existing relationships. Recruiting and retaining qualified channel partners and training them in our technologies requires significant time and resources. If we are unable to establish or maintain our indirect sales channels, our business and results of operations will be harmed. In addition, two worldwide distributors of our products together accounted for 24.5% and 24.8% of our total net revenue for the fiscal years 2008 and 2007, respectively. One worldwide distributor of our products accounted for 15.2% of our total net revenue for the three months ended June 30, 2009. A substantial reduction or delay in sales of our products to these distribution partners, if not replaced by sales to other indirect channel partners and distributors, could harm our business, operating results and financial condition.

Undetected software or hardware errors may harm our business and results of operations

Our products may contain undetected errors or defects when first introduced or as new versions are released. We have experienced these errors or defects in the past in connection with new products and product upgrades. We expect that these errors or defects will be found from time to time in new or enhanced products after commencement of commercial shipments. These problems may cause us to incur significant warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems. We may also be subject to liability claims for damages related to product errors or defects. While we carry insurance policies covering this type of liability, these policies may not provide sufficient protection should a claim be asserted. A material product liability claim may harm our business and results of operations.

Our products must successfully operate with products from other vendors. As a result, when problems occur in a network, it may be difficult to identify the source of the problem. The occurrence of software or hardware problems, whether caused by our products

or another vendor’s products, may result in the delay or loss of market acceptance of our products. The occurrence of any of these problems may harm our business and results of operations.

Adverse general economic conditions or reduced information technology spending may adversely impact our business

A substantial portion of our business depends on the demand for information technology by large enterprise customers and service providers, the overall economic health of our current and prospective customers and the continued growth and evolution of the Internet. National, regional and local economic conditions, such as recessionary economic cycles, protracted economic slowdown or further deterioration of the economy could adversely impact demand for our products. The purchase of our products is often discretionary and may involve a significant commitment of capital and other resources. Continued weak economic conditions or a reduction in information technology spending even if economic conditions improve would likely result in longer sales cycles and reduced product sales, each of which would adversely impact our business, results of operations and financial condition.

Our investments in auction rate securities are subject to risks that may cause losses and affect the liquidity of these investments

At June 30, 2009, the fair value of our AAA/A- (or equivalent) rated municipal auction rate securities (“ARS”) was approximately $41.5 million. Beginning in February 2008, auctions failed for approximately $53.4 million in par value of municipal ARS we held because sell orders exceeded buy orders. We may not be able to liquidate these investments and realize their full carrying value unless the issuer calls the security, a successful auction occurs, a buyer is found outside of the auction process, or the security matures. While we do not believe the decline in the carrying values of these municipal ARS is permanent, if the issuers of these securities are unable to successfully close future auctions and their credit ratings are lowered, we may be required to record future impairment charges related to these investments, which would harm our results of operations. We believe these investments may remain illiquid for longer than twelve months and as a result, we have classified these investments as long-term as of June 30, 2009.

Our operating results are exposed to risks associated with international commerce

As our international sales increase, our operating results become more exposed to international operating risks. These risks include risks related to recessionary economic cycles or protracted slowdowns in economies outside the United States, foreign currency exchange rates, managing foreign sales offices, regulatory, political or economic conditions in specific countries, military conflict or terrorist activities, changes in laws and tariffs, inadequate protection of intellectual property rights in foreign countries, foreign regulatory requirements and natural disasters. All of these factors could have a material adverse effect on our business. We intend to continue expanding into international markets. International sales represented 42.5% and 41.6% of our net revenues for the fiscal years ended September 30, 2008 and 2007, respectively, and 44.2% for the three months ended June 30, 2009. In particular, in fiscal year 2008, we derived 9.0% of our total revenue from the Japanese market. This revenue is dependent on a number of factors outside our control, including the viability and success of our resellers and the strength of the Japanese economy.

Changes in governmental regulations could negatively affect our revenues

Our products are subject to various regulations promulgated by the United States and various foreign governments including, but not limited to, environmental regulations and regulations implementing export license requirements and restrictions on the import or export of some technologies, especially encryption technology. Changes in governmental regulation and our inability or failure to obtain required approvals, permits or registrations could harm our international and domestic sales and adversely affect our revenues, business and operations.

Acquisitions present many risks and we may not realize the financial and strategic goals that are contemplated at the time of the transaction

With respect to our past acquisitions, as well as any other future acquisitions we may undertake, we may find that the acquired businesses, products or technologies do not further our business strategy as expected, that we paid more than what the assets are later worth or that economic conditions change, all of which may generate future impairment charges. Our acquisitions may be viewed negatively by customers, financial markets or investors. There may be difficulty integrating the operations and personnel of the acquired business, and we may have difficulty retaining the key personnel of the acquired business. We may have difficulty in integrating the acquired technologies or products with our existing product lines. Our ongoing business and management’s attention may be disrupted or diverted by transition or integration issues and the complexity of managing geographically and culturally diverse locations. We may have difficulty maintaining uniform standards, controls, procedures and policies across locations. We may experience significant problems or liabilities associated with product quality, technology and other matters.

Our inability to successfully operate and integrate newly-acquired businesses appropriately, effectively and in a timely manner, or to retain key personnel of any acquired business, could have a material adverse effect on our ability to take advantage of further growth in demand for integrated traffic management and security solutions and other advances in technology, as well as on our revenues, gross margins and expenses.

Our success depends on our key personnel and our ability to attract and retain qualified sales and marketing, operations, product development and professional services personnel

Our success depends to a significant degree upon the continued contributions of our key management, product development, sales, marketing and finance personnel, many of whom may be difficult to replace. The complexity of our application delivery networking products and their integration into existing networks and ongoing support, as well as the sophistication of our sales and marketing effort, requires us to retain highly trained professional services, customer support and sales personnel. Competition for qualified professional services, customer support and sales personnel in our industry is intense because of the limited number of people available with the necessary technical skills and understanding of our products. Our ability to retain and hire these personnel may be adversely affected by volatility or reductions in the price of our common stock, since these employees are generally granted restricted stock units or stock options. The loss of services of any of our key personnel, the inability to retain and attract qualified personnel in the future or delays in hiring qualified personnel, may harm our business and results of operations.

We face litigation risks

We are a party to lawsuits in the normal course of our business. Litigation in general, and intellectual property and securities litigation in particular, can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. Responding to lawsuits has been, and will likely continue to be, expensive and time-consuming for us. An unfavorable resolution of these lawsuits could adversely affect our business, results of operations or financial condition.

Our historical stock option practices and the restatement of our prior financial statements have exposed us to greater risks associated with litigation. Beginning in May 2006 several derivative actions were filed against certain current and former directors and officers (as discussed further in Item 1, Note 6, “Commitments and Contingencies — Legal Proceedings”) based on allegations relating to our historical stock option practices. We cannot assure you that this current litigation will result in the same conclusions reached by the special committee of outside directors formed by our Board of Directors to conduct a review of our stock option practices (the “Special Committee”).

We may in the future be subject to additional litigation arising in relation to our historical stock option practices and the restatement of our prior financial statements. Litigation may be time consuming, expensive and distracting for management from the conduct of our business. The adverse resolution of any lawsuit could have a material adverse effect on our business, financial condition and results of operations. We cannot assure you that any future litigation relating to our historical stock option practices will result in the same conclusions reached by the Special Committee. Furthermore, if we are subject to adverse findings in any of these matters, we could be required to pay damages or penalties or have other remedies imposed upon us which could adversely affect our business, results of operations or financial condition.

The matters relating to the Special Committee’s review of our historical stock option practices and the restatement of our consolidated financial statements has resulted in regulatory proceedings against us and may result in future regulatory proceedings, which could have a material adverse impact on our financial condition

On November 8, 2006, we announced that the Special Committee had completed its review of our historical stock option practices. Upon completion of its review, the Special Committee found that the recorded grant dates for certain stock options granted during fiscal years 1999 to 2004 should be adjusted as the measurement date for accounting purposes and the accounting treatment used for the vesting of certain stock options was incorrect. Based on the Special Committee’s review, to correct the accounting treatment, we amended our Annual Report on Form 10-K/A (as amended) for the year ended September 30, 2005 and our Quarterly Reports on Form 10-Q for the three months ended December 31, 2005 and March 31, 2006 to restate the consolidated financial statements contained in those reports.

In May 2006, we received notice from both the Securities and Exchange Commission (“SEC”) and the United States Attorney’s Office for the Eastern District of New York (the “Department of Justice”) that they were conducting informal inquiries into our historical stock option practices. We have fully cooperated with both agencies. Considerable legal and accounting expenses related to our historical stock option practices have been incurred and we may in the future be subject to additional regulatory proceedings or

actions arising in relation to our historical stock option practices and the restatement of our prior period financial statements. Any potential regulatory proceeding or action may be time consuming, expensive and distracting for management from the conduct of our business. The adverse resolution of any potential regulatory proceeding or action could adversely affect our business, results of operations or financial condition. We cannot assure you that the SEC and Department of Justice inquiries, or any future regulatory action relating to our historical stock option practices, will result in the same conclusions reached by the Special Committee. Furthermore, if we are subject to adverse findings in any of these matters, we could be required to pay damages or penalties or have other remedies imposed upon us, including criminal penalties, which could adversely affect our business, results of operations or financial condition.

Anti-takeover provisions could make it more difficult for a third party to acquire us

Our Board of Directors has the authority to issue up to 10,000,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the shareholders. The rights of the holders of common stock may be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change of control of our company without further action by our shareholders and may adversely affect the voting and other rights of the holders of common stock. Further, certain provisions of our bylaws, including a provision limiting the ability of stockholders to raise matters at a meeting of shareholders without giving advance notice, may have the effect of delaying or preventing changes in control or management of our company, which could have an adverse effect on the market price of our common stock. In addition, our articles of incorporation provide for a staggered board, which may make it more difficult for a third party to gain control of our Board of Directors. Similarly, state anti-takeover laws in the State of Washington related to corporate takeovers may prevent or delay a change of control of our company.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

At June 30, 2009, the fair value of our AAA/A- (or equivalent) rated municipal ARS was approximately $41.5 million. ARS are collateralized long-term debt instruments that provide liquidity through a Dutch auction process that resets the applicable interest rate at pre-determined intervals, typically every 7, 28 or 35 days. Beginning in February 2008, auctions failed for approximately $53.4 million in par value of municipal ARS we held because sell orders exceeded buy orders. When these auctions failed to clear, higher interest rates for those securities went into effect. However, the funds associated with these failed auctions will not be accessible until the issuer calls the security, a successful auction occurs, a buyer is found outside of the auction process, we exercise the Put Option with UBS, or the security matures. The underlying assets of the municipal ARS we hold, including the securities for which auctions have failed, are generally student loans which are guaranteed by the U.S. government. Based on our expected operating cash flows and our other sources of cash, we do not believe that any reduction in liquidity of our municipal ARS will have a material impact on our overall ability to meet our liquidity needs. We have the intent and ability to hold these securities until liquidation. These securities have been classified as long-term at June 30, 2009 based on the fact that we believe it could take longer than twelve months to liquidate the positions.

Management believes there have been no other material changes to our quantitative and qualitative disclosures about market risk during the nine month period ended June 30, 2009, compared to those discussed in our Annual Report on Form 10-K for the year ended September 30, 2008.

Item 4. Controls and Procedures

Our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are designed to ensure that required information is properly recorded, processed, summarized and reported within the required timeframe, as specified in the rules set forth by the SEC. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed is accumulated and communicated to management, including our Chief Executive Officer and Chief Accounting Officer, to allow timely decisions regarding required disclosures.

Our management, with the participation of our Chief Executive Officer and Chief Accounting Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2009. Based upon that evaluation, our Chief Executive Officer and Chief Accounting Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2009.

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) of the Exchange Act) during the period covered by this quarterly report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

We are not aware of any pending legal proceedings that, individually or in the aggregate, would have a material adverse effect on our business, operating results, or financial condition. We may in the future be party to litigation arising in the ordinary course of business, including claims that allegedly infringe upon third-party trademarks or other intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

Reference is made to Item 1, Note 6, “Commitments and Contingencies — Legal Proceedings,” of Part I of this Quarterly Report on Form 10-Q and Item 3, Legal Proceedings, in the Form 10-K, filed November 21, 2008 for descriptions of our legal proceedings. We continue to believe that the resolution of these legal proceedings will not have a material adverse effect on us and there have been no material developments since the time of the Form 10-K filing, except as noted in Item 1, Note 6 of Part I of this Quarterly Report on Form 10-Q.

Item 1A. Risk Factors
