Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation Organization Cavium, Inc., (the “Company”), was incorporated in the state of California on November 21, 2000 and was reincorporated in the state of Delaware effective February 6, 2007. The Company designs, develops and markets semiconductor processors for intelligent and secure networks. Basis of Presentation The condensed consolidated financial statements include the accounts of Cavium, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Prior to the closing of the acquisition of Xpliant, Inc. (“Xpliant”) in April 2015 as discussed in Note 5 of Notes to Condensed Consolidated Financial Statements, the Company accounted for Xpliant as a variable interest entity, or VIE. Under the accounting principles generally accepted in the United States of America, or US GAAP, a VIE is required to be consolidated by its primary beneficiary. The primary beneficiary is the party that absorbs a majority of the VIE’s anticipated losses and/or a majority of the expected returns. The condensed consolidated financial statements have been prepared in accordance with US GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, they do not include all of the information and footnotes required by US GAAP for annual financial statements. For further information, these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K (File No. 001-33435) on file with the SEC for the year ended December 31, 2015. The condensed consolidated financial statements contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to state fairly the Company’s condensed consolidated financial position at June 30, 2016, and the condensed consolidated results of its operations for the three and six months ended June 30, 2016 and 2015, and condensed consolidated statements of cash flows for the six months ended June 30, 2016 and 2015. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be expected for the full year. The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by US GAAP. Significant Accounting Policies The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. There had been no material changes to these accounting policies other than the accounting for stock-based compensation. For options granted beginning 2016, the Company used historical exercise patterns to estimate the expected life. Prior to 2016, the Company used the simplified method as permitted by the guidance on stock-based compensation to estimate the expected life. Recent Accounting Pronouncements In May 2014, the FASB issued a new guidance on the recognition of revenue from contracts with customers, which includes a single set of rules and criteria for revenue recognition to be used across all industries. The new revenue guidance’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the guidance requires five basic steps: identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when or as the entity satisfies a performance obligation. In August 2015, the FASB issued an update to defer the effective date by one year. In March 2016, the FASB issued amendments intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations and revenue from contracts with customers. This new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods during the annual period. Early adoption is allowed for annual reporting periods beginning after December 15, 2016. This new guidance may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company has not selected the transition method and is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements. In March 2016, the Financial Accounting Standards Board, or FASB, issued an update to the guidance on stock-based compensation. Under the new guidance, all excess tax benefits and tax deficiencies will be recognized in the income statement as they occur. This will replace the current guidance, which requires tax benefits that exceed compensation cost (windfalls) to be recognized in equity. It will also eliminate the need to maintain a “windfall pool,” and will remove the requirement to delay recognizing a windfall until it reduces current taxes payable. The new guidance will also change the cash flow presentation of excess tax benefits, classifying them as operating inflows, consistent with other cash flows related to income taxes. Today, windfalls are classified as financing activities. Also, most companies with stock-based compensation will show additional dilutive effects in earnings per share, or EPS, calculations. This is because there will no longer be excess tax benefits recognized in additional paid in capital. Today those excess tax benefits are included in assumed proceeds from applying the treasury stock method when computing diluted EPS. Under the amended guidance, companies will be able to make an accounting policy election to either (1) continue to estimate forfeitures or (2) account for forfeitures as they occur. This updated guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact this updated guidance on its consolidated financial statements and related disclosures. In February 2016, the FASB issued an updated guidance on leases. The core principle of this updated guidance is that a lessee should recognize the assets and lease liabilities on the balance sheet for certain leases classified as operating leases under previous GAAP. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. This updated guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact this updated guidance on its consolidated financial statements and related disclosures. In January 2016, the FASB issued an updated guidance on Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this updated guidance, among other things, requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. It requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Further, it requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). It also eliminates the requirement for entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this updated guidance are effective for annual and interim periods beginning after December 15, 2017. Early adoption is not permitted. The adoption of this updated guidance is not expected to have a material effect on the Company’s consolidated financial statements and related disclosures.

The Company leases certain design tools under capital lease and certain financing arrangements which are included in property and equipment, which total cost, net of accumulated amortization amounted to $17.8 million and $25.3 million at June 30, 2016 and December 31, 2015, respectively. Amortization expense related to assets recorded under capital lease and certain financing arrangements was $3.7 million and $3.7 million for the three months ended June 30, 2016 and 2015, respectively, and $7.5 million and $7.4 million for the six months ended June 30, 2016 and 2015, respectively.

The Company records reductions of revenue for pricing adjustments, such as competitive pricing programs and rebates, in the same period that the related revenue is recorded. The Company accrues the full potential rebates at the time of sale and does not apply a breakage factor. The reversal of the accrual of unclaimed rebate will be made if the specific rebate programs contractually end and when the Company believes that the unclaimed rebates are no longer subject to payment and will not be paid. Thus the reversal of unclaimed rebates may have a positive impact on the Company’s net revenue and net income in subsequent periods. Additional reductions of revenue would result if actual pricing adjustments exceed the estimates. Accrued rebates will vary in future periods based upon the level of overall sales to customers that participate in our rebate programs. Establishing accruals for rebates requires the use of judgment and estimates that impact the amount and timing of revenue recognition. For the three and six months ended June 30, 2016, the Company recorded estimated rebates amounting to $0.3 million and $0.3 million, respectively. There were no significant reversal or settlements during the three and six months ended June 30, 2016. As of June 30, 2016, total accrued rebates included within other accrued expenses and other current liabilities was $0.3 million.

Business Combinations [Abstract]
Business Combinations	5. Business Combination Pending Merger with QLogic Corporation On June 15, 2016, the Company entered into an Agreement and Plan of Merger with QLogic Corporation (“QLogic”), a supplier of high performance networking infrastructure solutions, (the “QLogic merger agreement”). Subject to the terms and conditions of the QLogic merger agreement, the Company is seeking to acquire all of the outstanding QLogic common stock for approximately $15.50 per share, comprised of $11.00 per share in cash and 0.098 of a share (valued based on the Company’s volume weighted trading price for the three trading days beginning June 10, 2016) of the Company’s common stock for each share of QLogic common stock through an exchange offer. Upon completion of the merger, QLogic will survive as a wholly owned subsidiary of the Company, and each issued and outstanding share of QLogic common stock, other than shares held in treasury, will be converted into the right to receive the merger consideration. The Company intends to fund the merger consideration with a combination of cash on hand, committed debt financing as discussed in detail below and issuance of new equity. This merger is primarily intended to provide an opportunity to the Company to drive significant growth at scale in data center and storage markets. As a result of the merger, subject to the terms and conditions of the QLogic merger agreement, at the effective time of the merger: (i) each outstanding and unvested QLogic stock option (other than any such unvested option which has an exercise price greater than merger consideration per share, an “underwater option”), shall be assumed by the Company and converted into an option to purchase, on the same terms and conditions as were applicable under such QLogic stock option, that number of shares of the Company’s common stock; (ii) each outstanding and vested QLogic stock option with an exercise price less than the sum of (a) the cash consideration and (b) the share consideration value, shall be cancelled and the holder thereof shall be entitled to receive vested option consideration; (iii) each outstanding QLogic stock option that is an Underwater Option shall be cancelled, and the holder thereof shall receive no payment on account thereof; (iv) the unvested QLogic restricted stock units, or RSU’s, outstanding immediately prior to the effective time shall be assumed and converted into RSUs of the Company’s common stock; (v) each outstanding and vested QLogic RSU unit shall be cancelled and extinguished and the holder thereof shall be entitled to receive an amount equal to the merger consideration that would be payable in respect of the total number of shares of QLogic Common Stock subject to such QLogic RSU; and (vi) the unvested QLogic performance based RSUs outstanding immediately prior to the effective time shall be assumed by the Company and converted into RSUs of the Company’s common stock. On June 15, 2016, the Company entered into a commitment letter (the “commitment letter”) with JPMorgan Chase Bank, N.A. (“JPMCB ”) pursuant to which JPMCB has committed to provide (i) a $650.0 million senior secured term loan facility and (ii) a $100.0 million senior secured interim term loan facility ((i) and (ii) together, the “facilities” and the provision of such funds as set forth in the commitment letter, the “financing”), subject to the execution of definitive documentation and satisfaction of customary closing conditions. The facilities are available to finance the exchange offer and the merger and pay fees and expenses related to the exchange offer, the merger and the financing. The interest rates per annum applicable to each term loan facility will be either (i) LIBOR plus the applicable margin or (ii) the base rate plus the applicable margin. The senior term loan facility will mature on the date that is 6 years after the closing date and the interim term loan facility will mature on February 15, 2017. Under the terms of the commitment letter, JPMCB will act as a joint lead arranger and a joint book running manager. The actual documentation governing the facilities has not been finalized, and accordingly, the actual terms may differ from the description of such terms in the commitment letter. The Company may increase the amount of borrowings under the senior secured term loan facility up to $700.0 million, and make a corresponding reduction up to $50.0 million of its borrowings under the senior secured interim loan facility. In May 2016, the Company engaged JPCMB as its financial advisor in connection with the pending merger with QLogic. The Company agreed to pay a transaction fee to JPCMB of $11.0 million, payable in installment, for the financial advisory services and rendering of an opinion as to the fairness, from the financial point of view, of the consideration to be paid by the Company in connection with the merger. The initial installment of $3.0 million is payable upon delivery of the fairness opinion and the balance shall be payable upon closing of the merger. The Company recorded the initial installment due in sales, general and administrative expense in the condensed consolidated statement of operations for the three months ended June 30, 2016 and the corresponding liability in the accrued expense and other current liabilities on the condensed consolidated balance sheet as of June 30, 2016. The QLogic merger agreement contains certain termination rights for the Company and QLogic, including, among others, if the transactions contemplated by the merger agreement are not consummated at or prior to November 12, 2016. Upon termination of the QLogic merger agreement under specified circumstances, including a termination by QLogic to enter into an agreement for an alternative transaction pursuant to the QLogic merger agreement, QLogic has agreed to pay the Company a termination fee of $47.8 million. The Company and QLogic have each made customary covenants in the QLogic merger agreement, including, without limitation, covenants not to solicit alternative transactions or, subject to certain exceptions, not to enter into discussions concerning, or provide confidential information in connection with, an alternative transaction, as more fully described in the merger agreement. The QLogic merger agreement has been unanimously approved by the boards of directors of the Company and QLogic. The merger is expected to close in the third quarter of calendar year 2016 pending customary closing conditions, including the tender into the exchange offer by QLogic stockholders of shares representing at least a majority of the outstanding shares of QLogic common stock, and the receipt of relevant regulatory approvals. Xpliant, Inc. Pursuant to the Agreement and Plan of Merger and Reorganization (“the Xpliant merger agreement”) between the Company and Xpliant, a final closing occurred on April 29, 2015 as discussed in detail below. Between May 2012 and March 2015, the Company entered into several note purchase agreements and promissory notes with Xpliant to provide cash advances. Xpliant was a Delaware incorporated and privately held company, engaged in the design and development of next generation software defined network switch chips. Prior to the closing of the merger pursuant to the Xpliant merger agreement, the Company concluded that Xpliant was a VIE as the Company was Xpliant’s primary beneficiary due to the Company’s involvement with Xpliant and the Company’s purchase option to acquire Xpliant. As such, the Company has included the accounts of Xpliant in the condensed consolidated financial statements. The Company had made total cash advances of $85.8 million, consisting of $10.0 million under nine convertible notes which, as amended, matured on August 31, 2014 and $75.8 million under several promissory notes which originally matured between April 2015 and March 2016. All promissory notes were cancelled as of July 31, 2015. On July 30, 2014, the Company entered into the Xpliant merger agreement, which was amended on October 8, 2014 and March 31, 2015 with Xpliant. Under the terms of the Xpliant merger agreement, as amended, the Company paid approximately $3.6 million in total cash consideration in exchange for all outstanding securities held by Xpliant’s stockholders. Pursuant to the Xpliant merger agreement, as amended, a first closing occurred on March 31, 2015 and the Company paid $2.5 million to Xpliant’s stockholders with respect to approximately 70% of the Xpliant stock outstanding and a second and final closing occurred on April 29, 2015 and the Company paid $1.1 million to Xpliant’s stockholders with respect to the then remaining approximately 30% of the Xpliant stock outstanding. Based on the substance of the transaction, the Company recorded the payments of cash consideration to Xpliant stockholders as a decrease to the Company’s additional paid-in capital within stockholders’ equity.

Stockholders Equity Note [Abstract]
Stockholders' Equity	7. Stockholders’ Equity Equity Incentive Plans On June15, 2016, the Company adopted the 2016 Equity Incentive Plan (the “2016 EIP”), which reserved 3,600,000 shares of the Company’s common stock. The 2016 EIP is intended as the successor to and continuation of the Company’s (the “2007 EIP”). The 2016 EIP provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards and other stock awards, which may be granted to employees, directors and consultants. Following the effective date, no additional awards may be granted under the 2007 EIP. All outstanding awards granted under the 2007 EIP will remain subject to the terms of such plan, provided however, that the following shares of common stock subject to any outstanding stock award granted under the 2007 EIP (collectively, the “2007 EIP Returning Shares”) will immediately be added to the share reserve as and when such shares become 2007 EIP Returning Shares and become available for issuance pursuant to awards granted under the 2016 EIP: . All awards granted on or after June 15, 2016 will be subject to the terms of the 2016 EIP. The following table summarizes the details related to stock options granted and outstanding under the Company’s equity and stock incentive plans for the six months ended June 30, 2016: Number of Options Outstanding Weighted Average Exercise Price Balance as of December 31, 2015 2,027,999 $ 24.75 Options granted 175,776 48.88 Options exercised (792,228 ) 7.92 Options cancelled and forfeited - - Balance as of June 30, 2016 1,411,547 37.20 The fair value of each option grant for the three and six months ended June 30, 2016 and 2015 were estimated on the date of grant using the Black-Scholes option-pricing model using the assumptions below. Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Risk-free interest rate - 1.34% 1.11% 1.34% to 1.41% Expected life - 3.77 years 4.96 years 3.77 to 4.58 years Dividend yield - 0% 0% 0% Volatility - 40.96% 42.51% 40.96% to 43.03% No stock options were granted during the three months ended June 30, 2016. The estimated weighted-average grant date fair value of options granted for the three months ended June 30, 2015 was $24.95 per share, and for the six months ended June 30, 2016 and 2015 was $18.65 per share and $23.79 per share, respectively. As of June 30, 2016, there was $5.0 million of unrecognized compensation costs, net of estimated forfeitures, related to stock options granted under the Company’s 2007 Equity Incentive Plan and 2001 Stock Incentive Plan. The unrecognized compensation cost is expected to be recognized over a weighted average period of 2.74 years. The following table summarizes the details related to restricted stock units, or RSUs, granted and outstanding under the 2007 Equity Incentive Plan for the six months ended June 30, 2016: Number of Shares Weighted- Average Grant Date Fair Value Per Share Balance as of December 31, 2015 2,194,068 $ 47.85 Granted 1,211,008 49.41 Issued and released (610,480 ) 45.11 Cancelled and forfeited (81,457 ) 55.12 Balance as of June 30, 2016 2,713,139 48.95 Included in the RSU grants in the table above was one-year performance-based RSUs granted in February 2016 for which the Company determined that the fair value of these performance RSU’s was $2.9 million. The Company recorded the related stock-based compensation expense based on its evaluation of the probability of achieving the milestones of all of the outstanding performance-based RSU’s as of June 30, 2016. At each reporting period, the Company evaluates the probability of achieving the milestone of each of the outstanding performance-based RSU’s and updates the recognition of related stock-based compensation expense. Also included in the RSU grants in the table above was a three-year vesting market-based RSU granted in February 2016. This market-based RSU will vest if: (i) during the performance period, the Company’s total stockholder return over a period of 30 consecutive trading days is equal to or greater than that of the industry index set by the compensation committee of the board of directors; and (ii) the recipient remains in continuous service with the Company through such vesting period. The fair value of the market-based RSU was determined by management using the Monte Carlo simulation method which takes into account multiple input variables that determine the probability of satisfying the market conditions stipulated in the award. This method requires the input of assumptions, including the expected volatility of the Company’s common stock, and a risk-free interest rate, similar to assumptions used in determining the fair value of the stock option grants discussed above. As such, the Company determined that the fair value of this market-based RSU was $3.3 million at the date of grant. The Company recorded the related stock-based compensation expense for the three and six months ended June 30, 2016 related to this grant. As of June 30, 2016, there was $105.7 million of unrecognized compensation costs, net of estimated forfeitures related to RSUs granted under the Company’s 2007 Equity Incentive Plan. The unrecognized compensation cost is expected to be recognized over a weighted average period of 2.57 years. Stock-Based Compensation The following table presents the detail of stock-based compensation expense amounts included in the condensed consolidated statement of operations for each of the periods presented: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 (in thousands) Cost of revenue $ 242 $ 185 $ 425 $ 382 Research and development 8,564 7,301 16,578 14,096 Sales, general and administrative 5,118 4,290 10,314 8,997 $ 13,924 $ 11,776 $ 27,317 $ 23,475 The total stock-based compensation cost capitalized as part of inventory as of June 30, 2016 and December 31, 2015 was not material.

Income Taxes

Income Taxes	Jun. 30, 2016
Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes The quarterly provision for income taxes is based on the estimated annual effective tax rate, plus any discrete items. The Company updates its estimate of its annual effective tax rate at the end of each quarterly period. The estimate takes into account estimations of annual pre-tax income (loss), the geographic mix of pre-tax income (loss) and interpretations of tax laws and the possible outcomes of current and future audits. The following table presents the provision for income taxes and the effective tax rates for the three and six months ended June 30, 2016 and 2015: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 (in thousands) Loss before income taxes $ (7,137 ) $ (5,694 ) $ (10,695 ) $ (19,284 ) Provision for income taxes 273 661 548 962 Effective tax rate (3.8 )% (11.6 )% (5.1 )% (5.0 )% The provision for income taxes for the three and six months ended June 30, 2016 and 2015 were primarily related to earnings in foreign jurisdictions. The difference between the provision for income taxes that would be derived by applying the statutory rate to the Company’s loss before income taxes and the provision for income taxes recorded for the three and six months ended June 30, 2016 and 2015 were primarily attributable to the difference in foreign tax rates and an increase in deferred tax liability related to the indefinite lived intangible assets. The Company’s net deferred tax assets relate predominantly to its U.S. tax jurisdiction. A full valuation allowance against the Company federal and state net deferred tax assets has been in place since 2012. The Company periodically evaluates the realizability of its net deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred tax assets is dependent on the Company's ability to generate sufficient future taxable income during periods prior to the expiration of tax attributes to fully utilize these assets. The Company weighed both positive and negative evidence and determined that there is a continued need for a valuation allowance as the Company is in a cumulative loss position over the previous three years, which is considered significant negative evidence. As such, the Company has not changed its judgment regarding the need for a full valuation allowance on its federal and state deferred tax assets as of December 31, 2015 and June 30, 2016. Until such time, consumption of tax attributes to offset profits will reduce the overall level of deferred tax assets subject to valuation allowance. Should the Company determine that it would be able to realize its remaining deferred tax assets in the foreseeable future, an adjustment to its remaining deferred tax assets would cause a material increase to net income in the period such determination is made. On July 27, 2015, the U.S. Tax Court in Altera Corp. v. Commissioner, 145 T.C. No. 3 (2015) issued an opinion with respect to Altera’s litigation with the Internal Revenue Service, concerning the treatment of stock-based compensation expense in an inter-company cost sharing arrangement. In ruling in favor of Altera, the Tax Court invalidated the portion of the Treasury regulations requiring the inclusion of stock-based compensation expense in such inter-company cost-sharing arrangements. Accordingly, the Company adjusted its inter-company arrangement to reflect the recent ruling; however, due to the valuation allowance against the Company’s federal and state net deferred tax assets, there was no material impact. On an ongoing basis, stock-based compensation will be excluded from intercompany charges.

Commitments and Contingencies The Company is not currently a party to any legal proceedings, the outcome of which, if determined adversely to the Company, would have a material adverse effect on the condensed consolidated financial position, condensed results of operations or condensed cash flows of the Company. The Company leases its facilities under non-cancelable operating leases, which contain renewal options and escalation clauses, and expire on various dates ending in October 2022. The Company also acquires certain assets under capital leases. Rent expense incurred under operating leases was $2.4 million and $1.9 million for the three months ended June 30, 2016 and 2015 The capital lease and technology license obligations include future cash payments payable primarily for license agreements with various outside vendors. For license agreements which qualify under capital lease and where installment payments extend beyond one year, the present value of the future installment payments are capitalized and included as part of intangible assets or property and equipment which is amortized over the estimated useful lives of the related licenses.

In consideration for this, Xpliant agreed to pay a $7.5 million manufacturing rights licensing fee and a per-unit royalty fee for certain ASIC products sold to certain customers for a limited time. The manufacturing rights licensing fee was payable in four equal quarterly payments, with the first installment payment was due on April 29, 2015 and each of the subsequent three installment payments were due on the first day of the following calendar quarter. The royalty shall be payable within 30 days after the end of each calendar quarter following the sale. Considering the terms of the purchase of the manufacturing rights, the Company recorded the full amount of the manufacturing rights licensing fee within research and development expense on the condensed consolidated statement of operations in the first quarter of 2015 and the related liability was recorded within other accrued expenses and other current liabilities on the condensed consolidated balance sheets. In 2015, the Company settled three installments due. The final installment payment was made in the first quarter of 2016. In July 2016, the Company signed the design kit license agreements with a third party vendor for an aggregate consideration of $9.0 million, payable in four equal installments. The first installment is due on the effective date of the agreement and the remaining installment payments are due in the succeeding quarters following the effective date. The Company has funding commitments related to the merger with QLogic. See Note 5 of Notes to Condensed Consolidated Financial Statements for related discussions.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	Organization Cavium, Inc., (the “Company”), was incorporated in the state of California on November 21, 2000 and was reincorporated in the state of Delaware effective February 6, 2007. The Company designs, develops and markets semiconductor processors for intelligent and secure networks.
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements include the accounts of Cavium, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Prior to the closing of the acquisition of Xpliant, Inc. (“Xpliant”) in April 2015 as discussed in Note 5 of Notes to Condensed Consolidated Financial Statements, the Company accounted for Xpliant as a variable interest entity, or VIE. Under the accounting principles generally accepted in the United States of America, or US GAAP, a VIE is required to be consolidated by its primary beneficiary. The primary beneficiary is the party that absorbs a majority of the VIE’s anticipated losses and/or a majority of the expected returns. The condensed consolidated financial statements have been prepared in accordance with US GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, they do not include all of the information and footnotes required by US GAAP for annual financial statements. For further information, these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K (File No. 001-33435) on file with the SEC for the year ended December 31, 2015. The condensed consolidated financial statements contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to state fairly the Company’s condensed consolidated financial position at June 30, 2016, and the condensed consolidated results of its operations for the three and six months ended June 30, 2016 and 2015, and condensed consolidated statements of cash flows for the six months ended June 30, 2016 and 2015. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be expected for the full year. The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by US GAAP.
Significant Accounting Policies	Significant Accounting Policies The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. There had been no material changes to these accounting policies other than the accounting for stock-based compensation. For options granted beginning 2016, the Company used historical exercise patterns to estimate the expected life. Prior to 2016, the Company used the simplified method as permitted by the guidance on stock-based compensation to estimate the expected life.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued a new guidance on the recognition of revenue from contracts with customers, which includes a single set of rules and criteria for revenue recognition to be used across all industries. The new revenue guidance’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the guidance requires five basic steps: identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when or as the entity satisfies a performance obligation. In August 2015, the FASB issued an update to defer the effective date by one year. In March 2016, the FASB issued amendments intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations and revenue from contracts with customers. This new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods during the annual period. Early adoption is allowed for annual reporting periods beginning after December 15, 2016. This new guidance may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company has not selected the transition method and is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements. In March 2016, the Financial Accounting Standards Board, or FASB, issued an update to the guidance on stock-based compensation. Under the new guidance, all excess tax benefits and tax deficiencies will be recognized in the income statement as they occur. This will replace the current guidance, which requires tax benefits that exceed compensation cost (windfalls) to be recognized in equity. It will also eliminate the need to maintain a “windfall pool,” and will remove the requirement to delay recognizing a windfall until it reduces current taxes payable. The new guidance will also change the cash flow presentation of excess tax benefits, classifying them as operating inflows, consistent with other cash flows related to income taxes. Today, windfalls are classified as financing activities. Also, most companies with stock-based compensation will show additional dilutive effects in earnings per share, or EPS, calculations. This is because there will no longer be excess tax benefits recognized in additional paid in capital. Today those excess tax benefits are included in assumed proceeds from applying the treasury stock method when computing diluted EPS. Under the amended guidance, companies will be able to make an accounting policy election to either (1) continue to estimate forfeitures or (2) account for forfeitures as they occur. This updated guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact this updated guidance on its consolidated financial statements and related disclosures. In February 2016, the FASB issued an updated guidance on leases. The core principle of this updated guidance is that a lessee should recognize the assets and lease liabilities on the balance sheet for certain leases classified as operating leases under previous GAAP. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. This updated guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact this updated guidance on its consolidated financial statements and related disclosures. In January 2016, the FASB issued an updated guidance on Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this updated guidance, among other things, requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. It requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Further, it requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). It also eliminates the requirement for entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this updated guidance are effective for annual and interim periods beginning after December 15, 2017. Early adoption is not permitted. The adoption of this updated guidance is not expected to have a material effect on the Company’s consolidated financial statements and related disclosures.
