| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Organization Super Micro Computer, Inc. (“Super Micro Computer”) was incorporated in 1993. Super Micro Computer is a global leader in server technology and green computing innovation. Super Micro Computer develops and provides high performance server solutions based upon an innovative, modular and open-standard architecture. Super Micro Computer has operations primarily in San Jose, California, the Netherlands, Taiwan, China and Japan. Basis of Presentation The consolidated financial statements reflect the consolidated balance sheets, results of operations and cash flows of Super Micro Computer, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany accounts and transactions have been eliminated in consolidation. The Company consolidates its investment in Super Micro Asia Science and Technology Park, Inc. as it is variable interest entity and the Company is the primary beneficiary. The noncontrolling interest is presented as a separate component from the Company's equity in the equity section of the Consolidated Balance Sheets. Net income attributable to the noncontrolling interest is not presented separately in the Consolidated Statements of Operations and is included in the general and administrative expenses as the amount is not material for any of the fiscal periods presented. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, but are not limited to: allowances for doubtful accounts and sales returns, inventory valuation, product warranty accruals, stock-based compensation, impairment of short-term and long-term investments and income taxes. Actual results could differ from those estimates. Fair Value of Financial Instruments The Company accounts for certain assets and liabilities at fair value. Accounts receivable and accounts payable are carried at cost, which approximates fair value due to the short maturity of these instruments. Cash equivalents and long-term investments are carried at fair value. Short-term and long-term debt is carried at amortized cost, which approximates its fair value based on borrowing rates currently available to the Company for loans with similar terms. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are: • Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; • Level 2 - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and • Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Cash and Cash Equivalents The Company considers all highly liquid instruments with an original maturity of three months or less from the date of purchase to be cash equivalents. Cash equivalents consist primarily of money market funds and certificates of deposits with maturities of less than three months. Long-term Investments The Company classifies its long-term investments in auction-rate securities ("auction rate securities") as long-term available-for-sale investments. Auction rate securities consist of municipal securities. The discounted cash flow model is used to estimate the fair value of the auction rate securities. These investments are recorded in the Consolidated Balance Sheets at fair value. Unrealized gains and losses on these investments are included as a component of accumulated other comprehensive income, net of tax. Inventory Inventory is valued at the lower of cost or market. Inventory consists of raw materials (principally components), work in process (principally products being assembled) and finished goods. Market value represents net realizable value for finished goods and work in process and replacement value of raw materials and parts. The Company evaluates inventory on a quarterly basis for lower of cost or market and excess and obsolescence and, as necessary, writes down the valuation of units to lower of cost or market or for excess and obsolescence based upon the number of units that are unlikely to be sold based upon estimated demand for the following twelve months as well as historical usage and sales activity. This evaluation takes into account matters including expected demand, historical usage and sales, anticipated sales price, product obsolescence and other factors. If actual future demand for the Company's products is less than currently forecasted, additional inventory adjustments may be required. Once a reserve is established, it is maintained until the product to which it relates is sold or scrapped. If a unit that has been written down is subsequently sold, the cost associated with the revenue from this unit is reduced to the extent of the write down, resulting in an increase in gross profit. The Company monitors the extent to which previously written down inventory is sold at amounts greater or less than carrying value, and based on this analysis, adjusts its estimate for determining future write downs. If in future periods, the Company experiences or anticipates a change in recovery rate compared with its historical experience, its gross margin would be affected. During fiscal years 2015 , 2014 and 2013 , the Company recorded a provision for lower of cost or market and excess and obsolete inventory totaling $5,928,000 , $2,254,000 and $9,725,000 , respectively. Property, Plant and Equipment Property, plant and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets as follows: Machinery and equipment 3 to 7 years Furniture and fixtures 5 years Software 3 to 5 years Buildings 39 years Building improvements 20 years Land improvements 15 years Leasehold improvements shorter of lease term or estimated useful life For assets acquired and financed under capital leases, the present value of the future minimum lease payments is recorded at the date of acquisition as property and equipment with the corresponding amount recorded as a capital lease obligation, and the amortization is computed on a straight-line basis over the shorter of lease term or estimated useful life. Other Assets As of June 30, 2015 , other assets consist primarily of a long-term deferred service costs of $1,490,000 , investments in privately held companies of $1,411,000 , a long-term prepaid royalty license of $997,000 and restricted cash of $840,000 . As of June 30, 2014 , other assets consist primarily of a long-term prepaid royalty license of $1,246,000 , an investment in a privately held company of $750,000 and restricted cash of $450,000 . Restricted cash consists primarily of certificates of deposits pledged as security for one irrevocable letter of credit required in connection with a warehouse lease in Fremont, California, one deposit to an escrow account required by the Company's worker's compensation program and bank guarantees in connection with office leases in the Netherlands. Long-Lived Assets The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount, an impairment loss would be measured based on the fair value of the asset compared to the carrying amount. No impairment charge has been recorded in any of the periods presented. Revenue Recognition The Company recognizes revenue from sales of products when persuasive evidence of an arrangement exists, shipment has occurred and title has transferred, the sales price is fixed or determinable, collection of the resulting receivable is reasonably assured, and all significant obligations have been met. Generally this occurs at the time of shipment when risk of loss and title has passed to the customer. The Company’s standard arrangement with its customers includes a signed purchase order or contract, 30 to 60 days payment terms, Ex-works terms, except for a few customers who have free-on-board destination terms, for which revenue is recognized when the products arrive at the destination. The Company generally does not provide for non-warranty rights of return except for products which have “Out-of-box” failure, where customers could return these products for credit within 30 days of receiving the items. Certain distributors and OEMs are also permitted to return products in unopened boxes, limited to purchases over a specified period of time, generally within 60 to 90 days of the purchase, or to products in the distributor’s or OEM’s inventory at certain times (such as the termination of the agreement or product obsolescence). To estimate reserves for future sales returns, the Company regularly reviews its history of actual returns for each major product line. The Company also communicates regularly with our distributors to gather information about end customer satisfaction, and to determine the volume of inventory in the channel. Reserves for future returns are adjusted as necessary, based on returns experience, returns expectations and communication with distributors In addition, certain customers have acceptance provisions and revenue is deferred until the customers provide the necessary acceptance. At June 30, 2015 and 2014 , the Company had deferred revenue of $459,000 and $7,665,000 and related deferred product costs of $219,000 and $6,674,000 , respectively, related to shipments to customers pending acceptance. Probability of collection is assessed on a customer-by-customer basis. Customers are subjected to a credit review process that evaluates the customers’ financial position and ability to pay. If it is determined from the outset of an arrangement that collection is not probable based upon the review process, the customers are required to pay cash in advance of shipment. The Company also makes estimates of the uncollectibility of accounts receivable, analyzing accounts receivable and historical bad debts, customer concentrations, customer-credit-worthiness, current economic trends and changes in customer payment terms to evaluate the adequacy of the allowance for doubtful accounts. On a quarterly basis, the Company evaluates aged items in the accounts receivable aging report and provides an allowance in an amount the Company deems adequate for doubtful accounts. Our provision for bad debt was $326,000 , $1,476,000 and $929,000 in fiscal years 2015 , 2014 and 2013 , respectively. If a major customer's creditworthiness deteriorates, if actual defaults are higher than the Company's historical experience, or if other circumstances arise, the Company's estimates of the recoverability of amounts due to the Company could be overstated, and additional allowances could be required, which could have an adverse impact on its reported operating expenses. The Company provides for price protection to certain distributors. The Company assesses the market competition and product technology obsolescence, and makes price adjustments based on its judgment. Upon each announcement of price reductions, the accrual for price protection is calculated based on the distributors’ inventory on hand. Such reserves are recorded as a reduction to revenue at the time the Company reduces the product prices. The Company has an immaterial amount of service revenue relating to on-site service and non-warranty repairs. Revenue for on-site service is recognized over the contracted service period, and revenue for non-warranty repair service is recognized upon shipment of the repaired units to customers. Service revenue has been less than 10% of net sales for all periods presented and is not separately disclosed. Cost of Sales Cost of sales primarily consists of the costs of materials, contract manufacturing, in-bound shipping, personnel and related expenses, equipment and facility expenses, warranty costs and provision for lower of cost or market and excess and obsolete inventory. Product Warranties The Company offers product warranties ranging from 15 to 39 months against any defective products. The Company accrues for estimated returns of defective products at the time revenue is recognized based on historical warranty experience and recent trends. The Company monitors warranty obligations and may make revisions to its warranty reserve if actual costs of product repair and replacement are significantly higher or lower than estimated. Accruals for anticipated future warranty costs are charged to cost of sales and included in accrued liabilities. The Company’s estimates and assumptions used have been historically close to actual. If in future periods the Company experiences or anticipates an increase or decrease in warranty claims as a result of new product introductions or changes in unit volumes compared with its historical experience, or if the cost of servicing warranty claims is greater or lesser than expected, the Company intends to adjust its estimates appropriately. The following table presents for the years ended June 30, 2015 , 2014 and 2013 , the reconciliation of the changes in accrued warranty costs which is included as a component of accrued liabilities (in thousands): June 30, 2015 2014 2013 Balance, beginning of year $ 7,083 $ 6,472 $ 5,522 Provision for warranty 15,771 14,175 13,438 Costs charged to accrual (14,950 ) (13,950 ) (12,487 ) Change in estimated liability for pre-existing warranties (204 ) 386 (1 ) Balance, end of year $ 7,700 $ 7,083 $ 6,472 Software Development Costs Software development costs are included in research and development and are expensed as incurred. Software development costs are capitalized beginning when technological feasibility has been established and ending when a product is available for general release to customers. To date, the period between achieving technological feasibility and the issuance of such software has been short and software development costs qualifying for capitalization have been insignificant. Research and Development Research and development costs are expensed as incurred and consist primarily of salaries, consulting services, other direct expenses and other engineering expenses. The Company occasionally receives funding from certain suppliers and customers towards its development efforts. Such amounts are recorded as a reduction of research and development expenses and were $6,318,000 , $3,132,000 and $2,112,000 for the years ended June 30, 2015 , 2014 and 2013 , respectively. Cooperative Marketing Arrangements The Company has arrangements with resellers of its products to reimburse the resellers for cooperative marketing costs meeting specified criteria. The Company accrues the cooperative marketing costs based on these arrangements and its estimate for resellers’ claims for marketing activities. The Company records marketing costs meeting such specified criteria within sales and marketing expenses in the consolidated statements of operations. For those marketing costs that do not meet the specified criteria, the amounts are recorded as a reduction to sales in the consolidated statements of operations. Total cooperative marketing costs charged to sales and marketing expenses for the years ended June 30, 2015 , 2014 and 2013 , were $1,995,000 , $2,058,000 and $1,550,000 , respectively. Total amounts recorded as reductions to sales for the years ended June 30, 2015 , 2014 and 2013 , were $4,200,000 , $2,829,000 and $2,610,000 , respectively. Advertising Costs Advertising costs are expensed as incurred. Total advertising and promotional expenses, including cooperative marketing payments, were $7,263,000 , $5,183,000 and $4,085,000 for the years ended June 30, 2015 , 2014 and 2013 , respectively. Stock-Based Compensation The Company measures and recognizes the compensation expense for all share-based awards made to employees and non-employee members of the Board of Directors, including employee stock options and restricted stock units. The Company is required to estimate the fair value of share-based awards on the date of grant. The value of awards that are ultimately expected to vest is recognized as an expense over the requisite service periods. The fair value of our restricted stock units is based on the closing market price of the Company's common stock on the date of grant. The Company estimated the fair value of stock options granted using a Black-Scholes option pricing model and a single option award approach. This model requires the Company to make estimates and assumptions with respect to the expected term of the option, the expected volatility of the price of the Company's common stock and the expected forfeiture rate. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The expected term represents the period that the Company's stock-based awards are expected to be outstanding and was determined based on a combination of the Company's peer group and historical experience. The expected volatility is based on a combination of the Company's implied and historical volatility. In addition, forfeitures of share-based awards are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option and restricted stock unit forfeitures and record stock-based compensation expense only for those awards that are expected to vest. Shipping and Handling Fees The Company incurred shipping costs of $2,090,000 , $1,605,000 and $1,475,000 for the years ended June 30, 2015 , 2014 and 2013 , respectively, which were included in sales and marketing expenses. Income Taxes The Company accounts for income taxes under an asset and liability approach. Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax reporting purposes, net operating loss carry-forwards and other tax credits measured by applying currently enacted tax laws. Valuation allowances are provided when necessary to reduce deferred tax assets to an amount that is more likely than not to be realized. The Company recognizes the tax liability for uncertain income tax positions on the income tax return based on the two-step process. The first step is to determine whether it is more likely than not that each income tax position would be sustained upon audit. The second step is to estimate and measure the tax benefit as the amount that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. Estimating these amounts requires the Company to determine the probability of various possible outcomes. The Company evaluates these uncertain tax positions on a quarterly basis. This evaluation is based on the consideration of several factors, including changes in facts or circumstances, changes in applicable tax law, settlement of issues under audit and new exposures. If the Company later determines that its exposure is lower or that the liability is not sufficient to cover its revised expectations, the Company adjusts the liability and effects a related change in its tax provision during the period in which the Company makes such determination. Foreign Currency Translation The functional currency of the Company’s international subsidiaries is the U.S. dollar. Assets and liabilities of the Company's international subsidiaries that are denominated in the local currency are remeasured into U.S. dollars at period-end exchange rates and revenue and expenses that are denominated in the local currency are remeasured into U.S. dollars at the average exchange rates during the period. Accordingly, remeasurement of foreign currency accounts and foreign exchange transaction gains and losses, which have not been material, are reflected in the consolidated statements of operations. Net Income Per Common Share The Company’s restricted share awards are subject to repurchase and settled in shares of common stock upon vesting. Such awards have the nonforfeitable right to receive dividends on an equal basis with common stock and therefore are considered participating securities that must be included in the calculation of net income per share using the two-class method. Under the two-class method, basic and diluted net income per common share is determined by calculating net income per share for common stock and participating securities based on participation rights in undistributed earnings. Diluted net income per common share is calculated by adjusting outstanding shares, assuming any dilutive effects of stock incentive awards calculated using the treasury stock method. Under the treasury stock method, an increase in the fair market value of our common stock results in a greater dilutive effect from outstanding stock options and restricted stock units. Additionally, the exercise of employee stock options and the vesting of restricted stock units results in a further dilutive effect on net income per share. The computation of basic and diluted net income per common share using the two-class method is as follows (in thousands, except per share amounts): Years Ended June 30, 2015 2014 2013 Basic net income per common share calculation Net income $ 101,863 $ 54,157 $ 21,279 Less: Undistributed earnings allocated to participating securities — (36 ) (106 ) Net income attributable to common shares—basic $ 101,863 $ 54,121 $ 21,173 Weighted-average number of common shares used to compute basic net income per common share 46,434 43,599 41,992 Basic net income per common share $ 2.19 $ 1.24 $ 0.50 Diluted net income per common share calculation Net income $ 101,863 $ 54,157 $ 21,279 Less: Undistributed earnings allocated to participating securities — (34 ) (101 ) Net income attributable to common shares—diluted $ 101,863 $ 54,123 $ 21,178 Weighted-average number of common shares used to compute basic net income per common share 46,434 43,599 41,992 Dilutive effect of options and restricted stock units to purchase common stock 3,660 2,913 1,915 Weighted-average number of common shares used to compute diluted net income per common share 50,094 46,512 43,907 Diluted net income per common share $ 2.03 $ 1.16 $ 0.48 For the years ended June 30, 2015 , 2014 and 2013 , the Company had stock options and restricted stock units outstanding that could potentially dilute basic earnings per share in the future, but were excluded from the computation of diluted net income per share in the periods presented, as their effect would have been anti-dilutive. The anti-dilutive common share equivalents resulting from outstanding equity awards were 3,805,000 , 3,465,000 and 6,241,000 for the years ended June 30, 2015 , 2014 and 2013 , respectively. Certain Significant Risks and Uncertainties The Company operates in the high technology industry and is subject to a number of risks, some of which are beyond the Company’s control, that could have a material adverse effect on the Company’s business, operating results, and financial condition. These risks include variability and uncertainty of revenues and operating results; product obsolescence; geographic concentration; international operations; dependence on key personnel; competition; intellectual property claims and litigation; management of growth; and limited sources of supply. Concentration of Supplier Risk Certain raw materials used by the Company in the manufacture of its products are available from a limited number of suppliers. Shortages could occur in these essential materials due to an interruption of supply or increased demand in the industry. One supplier accounted for 28.7% , 23.4% , and 21.9% of total purchases for the years ended June 30, 2015 , 2014 and 2013 , respectively. Ablecom Technology, Inc., a related party of the Company as noted in Note 9, accounted for 12.6% , 16.1% and 18.9% of total purchases for the years ended June 30, 2015 , 2014 and 2013 , respectively. Concentration of Credit Risk Financial instruments which potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents and long-term investments and accounts receivable. One customer accounted for 10.1% of net sales in fiscal year 2015. No single customer accounted for 10% or more of net sales in fiscal years 2014 and 2013 . No customer accounted for 10% or more of accounts receivable as of June 30, 2015 and 2014 . Adoption of New Accounting Pronouncements In July 2013, the FASB issued authoritative guidance associated with the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. It requires a liability related to an unrecognized tax benefit to offset a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if a settlement is required or expected in the event the uncertain tax position is disallowed. The Company adopted the new disclosure on July 1, 2014. The adoption of this guidance did not have a material impact on our results of operations or financial position. In May 2014, the FASB issued new accounting guidance related to revenue recognition. This new standard replaces all current U.S. GAAP guidance on revenue, eliminates all industry-specific guidance and provides a unified model in determining 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 can be applied either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The new standard is effective for the Company on July 1, 2018. The Company is currently evaluating the effect the guidance will have on the Company's financial statement disclosures, results of operations or financial position. In April 2015, the FASB issued new accounting guidance related to presentation of debt issue costs. The new standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The new standard is effective for the Company on July 1, 2016. The Company is currently evaluating the effect the guidance will have on the Company's financial statement disclosures, results of operations and financial position. In July 2015, the FASB issued authoritative guidance related to inventory measurement. The new standard requires entities to measure inventory at the lower of cost and net realizable value thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. The new standard is effective for the Company on July 1, 2017 . The Company is currently evaluating the effect the guidance will have on the Company's financial statement disclosures, results of operations and financial position. |
