The accompanying interim consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. These financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in the accompanying financial statements. | |||||||||
Certain information and footnote disclosures normally included in the Company’s annual audited consolidated financial statements and accompanying notes have been condensed in, or omitted from these interim financial statements. Accordingly, the unaudited consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2013, filed with the Securities and Exchange Commission on March 3, 2014. | |||||||||
The results of operations presented in this quarterly report on Form 10-Q are not necessarily indicative of the results of operations that may be expected for any future periods. In the opinion of management, these unaudited consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, that are necessary for a fair statement of the results of all interim periods reported herein. | |||||||||
Recent Accounting Pronouncements | |||||||||
In May 2014, the Financial Accounting Standards Board issued updated guidance and disclosure requirements for recognizing revenue. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance will be effective for the Company on January 1, 2017 and may be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the potential impact of adopting this new accounting guidance. | |||||||||
Revision of Prior Period Amounts | |||||||||
During the third quarter of 2013, the Company identified immaterial classification errors in its historical consolidated statements of cash flows. The errors relate to the timing of cash payments for property and equipment, cash receipts from employees for common stock related to the Company's employee stock purchase plan and cash payments for lease deposits. The cash flows for these items were improperly reflected as changes in operating assets and liabilities rather than as investing or financing activities. There was no impact to the net change in cash and cash equivalents. The Company concluded these errors are immaterial to all annual and quarterly periods previously presented and has reflected the corrections as a revision to the consolidated statements of cash flows previously filed. | |||||||||
The effect of the revisions to the consolidated statements of cash flows for the six months ended June 30, 2013, is as follows (in thousands): | |||||||||

Unrealized gains and unrealized temporary losses on investments classified as available-for-sale are included within accumulated other comprehensive income (loss) in the consolidated balance sheets. Upon realization, those amounts are reclassified from accumulated other comprehensive income (loss) to interest income in the statements of operations. The Company holds for investment one corporate bond, which is classified as an available-for-sale marketable security, in a continuous unrealized loss position for more than 12 months, with an insignificant unrealized loss and a fair value of $1.9 million as of June 30, 2014. The unrealized loss is attributable to changes in interest rates. The Company does not believe any unrealized losses represent other than temporary impairments based on the evaluation of available evidence. As of December 31, 2013, there were no securities in a continuous unrealized loss position for more than 12 months. | ||||||||||||||||||||||||

As of June 30, 2014 and December 31, 2013, the Company grouped money market funds and certificates of deposit using a Level 1 valuation because market prices for such investments are readily available in active markets. As of June 30, 2014 and December 31, 2013, the Company grouped commercial paper, U.S. government agency obligations and corporate bonds using a Level 2 valuation because quoted prices for identical or similar assets are available in markets that are inactive. | ||||||||||||||||||||||||
When developing fair value estimates, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. When available, the Company uses quoted market prices to measure fair value. The valuation technique used to measure fair value for the Company's Level 1 and Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets. If market prices are not available, the fair value measurement is based on models that use primarily market-based parameters including yield curves, volatilities, credit ratings and currency rates. In certain cases where market rate assumptions are not available, the Company is required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument. | ||||||||||||||||||||||||
The valuation technique used to measure fair value of the Company's Level 3 liability, which consists of contingent consideration related to the acquisition of Velocius Networks, Inc. ("Velocius") (Note 5), is primarily an income approach. The significant unobservable input used in the fair value measurement of the Velocius contingent consideration is the likelihood of achieving development milestones to integrate the acquired technology into the Company's technology. | ||||||||||||||||||||||||
The valuation technique used to measure fair value for the Company's Level 3 asset, which consisted of a $25.0 million face value convertible note receivable, is primarily an income approach, where the expected weighted average future cash flows are discounted back to present value. The significant unobservable inputs used in the fair value measurement of the convertible note receivable are the probability of conversion to equity and the fair value of equity into which the note is convertible. In the second quarter of 2014, the note was amended. Under the terms of the amendment, the note became convertible into shares of preferred stock of the issuer valued at $12.5 million at the time of conversion; $6.3 million became due and payable (and was paid) during the second quarter of 2014 and the balance of $6.3 million is due and payable in the third quarter of 2014. | ||||||||||||||||||||||||
Increases or decreases in the underlying assumptions used to value the Company's Level 3 assets and liabilities held at June 30, 2014 and December 31, 2013, could increase or decrease the fair value estimates recorded in the consolidated balance sheets. | ||||||||||||||||||||||||

Prolexic Acquisition | ||||||
On February 18, 2014, the Company acquired all of the outstanding preferred and common stock of Prolexic Technologies, Inc. ("Prolexic") in exchange for $392.1 million in cash and the assumption of unvested stock options. The goal of acquiring Prolexic is to provide customers with a comprehensive portfolio of security solutions designed to defend an enterprise’s Web and IP infrastructure against application-layer, network-layer and data center attacks delivered via the Internet. The consolidated financial statements include the operating results of Prolexic from the date of acquisition. The revenue and earnings included in the Company's consolidated financial statements since the acquisition date are not material. Pro forma results of the operations have not been presented because the effects are not material to the consolidated financial statements. Acquisition-related costs were $4.1 million for the six months ended June 30, 2014. | ||||||
The allocation of the purchase price has been finalized, with the exception of evaluating certain accrued expenses, property and equipment and tax-related assets and liabilities. The Company is in the process of gathering the facts and circumstances existing as of the acquisition date in order to finalize the valuation of these items. During the second quarter of 2014, the Company made immaterial adjustments to the allocation of the purchase price. | ||||||

On November 8, 2013, the Company acquired Velocius in exchange for $4.3 million in cash. In addition, the Company recorded a liability of $2.6 million for contingent consideration related to expected achievement of post-closing milestones. The maximum potential payout of the contingent consideration is $3.0 million and as of June 30, 2014, the fair value of the liability is $2.9 million. | ||||||
The Company acquired Velocius with a goal of complementing its hybrid cloud optimization strategy for optimizing IP application traffic across the Internet for remote and branch-end users. The Company allocated $5.4 million of the cost of the acquisition to goodwill and $2.5 million to acquired intangible assets. The allocation of the purchase price was finalized in the first quarter of 2014. The total weighted average useful life of the intangible assets acquired from Velocius is 7.9 years. The value of the goodwill from the acquisition can be attributed to a number of business factors, including a trained technical workforce and cost synergies. The total amount of goodwill related to the acquisition of Velocius expected to be deducted for tax purposes is $0.3 million. | ||||||
Strategic Network Transaction | ||||||
On November 30, 2012, the Company entered into a strategic alliance with AT&T Services, Inc. ("AT&T"). Under the agreement, AT&T became a reseller of the Company's services and the Company acquired certain assets and contracted to purchase bandwidth, co-location and related services from AT&T. The total consideration was $55.0 million, of which $27.5 million was paid during the third quarter of 2013 and $27.5 million was paid during the first quarter of 2014. |

Convertible Senior Notes | ||||||||
In February 2014, the Company issued $690.0 million par value of convertible senior notes due 2019 (the "Notes"). The Notes are senior unsecured obligations of the Company, do not bear regular interest and mature on February 15, 2019, unless repurchased or converted prior to maturity. | ||||||||
At their option, holders may convert their Notes prior to the close of business on the business day immediately preceding August 15, 2018 only under the following circumstances: | ||||||||
• | during any calendar quarter commencing after the calendar quarter ended June 30, 2014 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; | |||||||
• | during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; or | |||||||
• | upon the occurrence of specified corporate events. | |||||||
On or after August 15, 2018, holders may convert all or any portion of their Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date, regardless of the foregoing circumstances. | ||||||||
Upon conversion, the Company, at its election, may pay or deliver to holders cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock. The initial conversion rate is 11.1651 shares of the Company's common stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $89.56 per share, subject to adjustments in certain events, and represents a potential conversion into 7.7 million shares. | ||||||||
In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying cost of the liability component was calculated by measuring the fair value of a similar debt obligation that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes and the proceeds allocated to the liability component (“debt discount”), is amortized to interest expense using the effective interest method over the term of the Notes. The equity component is recorded in additional paid-in capital in the consolidated balance sheet and will not be remeasured as long as it continues to meet the conditions for equity classification. | ||||||||
In accounting for the transaction costs related to the issuance of the Notes, the Company allocated the total transaction costs incurred to the liability and equity components based on their relative values. Transaction costs attributable to the liability component are being amortized to interest expense over the term of the Notes, and transaction costs attributable to the equity component are netted with the equity component of the Notes in stockholders’ equity. | ||||||||
The Notes consist of the following components (in thousands): | ||||||||
June 30, 2014 | ||||||||
Liability component: | ||||||||
Principal | $ | 690,000 | ||||||
Less: debt discount, net of amortization | (94,615 | ) | ||||||
Net carrying amount | $ | 595,385 | ||||||
Equity component: | $ | 101,276 | ||||||
The estimated fair value of the Company's Notes at June 30, 2014 was $705.8 million. The fair value was determined based on data points other than quoted prices that are observable, either directly or indirectly, and has been classified as Level 2 within the fair value hierarchy. Based on the closing price of the Company's common stock of $61.06 on June 30, 2014, the value of the Notes if converted to common stock was less than the principal amount of $690.0 million. | ||||||||
The Company used $62.0 million of the proceeds from the offering to repurchase shares of its common stock, concurrently with the issuance of the Notes. The repurchase was made in accordance with the stock repurchase plan previously approved by the Board of Directors (Note 7). Additionally, $23.3 million of the proceeds was used for the net cost of convertible note hedge and warrant transactions. The Company intends to use the remaining net proceeds for working capital and other general corporate purposes, as well as for potential acquisitions and strategic transactions. | ||||||||
Note Hedge | ||||||||
To minimize the impact of potential dilution upon conversion of the Notes, the Company entered into convertible note hedge transactions with respect to its common stock. The Company paid $101.3 million for the note hedge transactions. The note hedge transactions cover approximately 7.7 million shares of the Company’s common stock at a strike price that corresponds to the initial conversion price of the Notes, also subject to adjustment, and are exercisable upon conversion of the Notes. The note hedge transactions are intended to reduce dilution in the event of conversion of the Notes. | ||||||||
Warrants | ||||||||
Separately, the Company entered into warrant transactions, whereby the Company sold warrants to acquire, subject to anti-dilution adjustments, up to 7.7 million shares of the Company’s common stock at a strike price of approximately $104.49 per share. The Company received aggregate proceeds of $78.0 million from the sale of the warrants. The convertible note hedge and warrant transactions will generally have the effect of increasing the conversion price of the Notes to approximately $104.49 per share. | ||||||||
Interest Expense | ||||||||
The Notes do not bear regular interest, but have an effective interest rate of 3.2% attributable to the conversion feature. The following table sets forth total interest expense included in the statement of operations related to the Notes (in thousands): | ||||||||

The Company’s effective income tax rate, including discrete items, was 36.2% and 34.0% for the six months ended June 30, 2014 and 2013, respectively. The effective income tax rate is based upon estimated income for the year, the estimated composition of the income in different jurisdictions and discrete adjustments, if any, in the applicable quarterly periods, including retroactive changes in tax legislation, settlements of tax audits or assessments, the resolution or identification of tax position uncertainties and acquisitions of other companies. The discrete items in the first six months of 2014 include a deferred tax charge, the tax effect of certain stock options and interest and penalties related to uncertain tax positions. | |
For the six months ended June 30, 2014, the effective income tax rate was higher than the federal statutory tax rate mainly due to the effects of accounting for stock-based compensation in accordance with the authoritative guidance for share-based payments and state income tax, partially offset by income from foreign jurisdictions with lower tax rates. For the six months ended June 30, 2013, the effective income tax rate was lower than the federal statutory tax rate mainly due to the composition of income in foreign jurisdictions that is taxed at lower rates compared to the statutory tax rates in the United States, as well as the reinstatement of the federal research and development credit at the beginning of 2013, which included a one-time retroactive impact for fiscal year 2012. |

Basic net income per share is computed using the weighted average number of common shares outstanding during the applicable period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential common stock. Potential common stock consists of shares issuable pursuant to stock options, restricted stock units (“RSUs”), deferred stock units, convertible senior notes and warrants issued by the Company. The dilutive effect of outstanding awards and convertible securities is reflected in diluted earnings per share by application of the treasury stock method. | ||||||||||||||||

The calculation of assumed proceeds used to determine the diluted weighted average shares outstanding under the treasury stock method in the periods presented was adjusted by tax windfalls and shortfalls associated with all of the Company’s outstanding stock awards. Such windfalls and shortfalls are computed by comparing the tax deductible amount of outstanding stock awards to their grant date fair values and multiplying the results by the applicable statutory tax rate. A positive result creates a windfall, which increases the assumed proceeds, and a negative result creates a shortfall, which reduces the assumed proceeds. |
