Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies
	(a) Basis of Presentation
	Except for the Consolidated Balance Sheet of MicroStrategy Incorporated (“MicroStrategy” or the “Company”) as of December 31, 2014, which was derived from audited financial statements, the accompanying Consolidated Financial Statements are unaudited. In the opinion of management, all adjustments necessary for a fair statement of such financial position and results of operations have been included. All such adjustments are of a normal recurring nature unless otherwise disclosed. Interim results are not necessarily indicative of results for a full year.
	Certain amounts in the prior year’s Consolidated Financial Statements and Notes to Consolidated Financial Statements have been reclassified to conform to current year presentation. Revenues and cost of revenues have been reclassified in the Consolidated Statements of Operations to reflect the separate components of total product licenses and subscription services, and unrealized gains and losses on foreign currency forward contracts have been reclassified within the operating section in the Consolidated Statements of Cash Flows.
	The Consolidated Financial Statements and Notes to Consolidated Financial Statements are presented as required by the United States Securities and Exchange Commission (“SEC”) and do not contain certain information included in the Company’s annual financial statements and notes. These financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto filed with the SEC in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. There have been no significant changes in the Company’s accounting policies since December 31, 2014.
	The accompanying Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Recent Accounting Standards	(2) Recent Accounting Standards
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740) (“ASU 2013-11”), which requires the financial statement presentation of an unrecognized tax benefit in a particular jurisdiction, or a portion thereof, as a reduction to a deferred tax asset for a net operating loss (“NOL”) carryforward, a similar tax loss, or a tax credit carryforward, unless the uncertain tax position is not available to reduce, or would not be used to reduce, the NOL or carryforward under the tax law in the same jurisdiction; otherwise, the unrecognized tax benefit should be presented as a gross liability and should not be combined with a deferred tax asset. The Company adopted ASU 2013-11 on January 1, 2014. As a result, liabilities for unrecognized tax benefits of $1.2 million were netted against deferred tax assets, as of March 31, 2015. The adoption of this guidance did not have a material effect on the Company’s consolidated results of operations or cash flows.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance. The standard’s core principle is that an entity should recognize revenue when it transfers 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. The standard creates a five-step model to achieve its core principle: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the separate performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. In addition, entities must disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative disclosures are required about: (1) the entity’s contracts with customers, (2) the significant judgments, and changes in judgments, made in applying the guidance to those contracts, and (3) any assets recognized from the costs to obtain or fulfill a contract with a customer. ASU 2014-09 is effective for interim and annual periods beginning January 1, 2017. Early adoption is not permitted. The standard allows entities to apply the standard retrospectively to each prior reporting period presented (“full retrospective adoption”) or retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application (“modified retrospective adoption”). The Company is currently evaluating the impact of this guidance on its consolidated financial position, results of operations, and cash flows.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended
	Mar. 31, 2015
Fair Value Measurements	(3) Fair Value Measurements
	The Company measures certain assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that is expected to be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a three-level hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. The three levels of the fair value hierarchy are described below:
		Level 1:		Quoted (unadjusted) prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
		Level 2:		Inputs other than quoted prices that are either directly or indirectly observable, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		Level 3:		Inputs that are generally unobservable, supported by little or no market activity, and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability.
	The categorization of an asset or liability within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The valuation techniques used by the Company when measuring fair value maximize the use of observable inputs and minimize the use of unobservable inputs.
	The Company is exposed to certain risks related to its ongoing business operations, including the effect of changes in foreign exchange rates on the Company’s monetary assets and liabilities denominated in foreign currency. The Company uses foreign currency forward contracts as part of its strategy to manage these risks, but does not hold or issue derivative instruments for trading purposes or speculation. The Company executes these instruments with financial institutions that hold an investment grade credit rating. These foreign currency forward contracts do not meet the requirements for hedge accounting and are recorded on the balance sheet as either an asset or liability measured at their fair value as of the reporting date. Changes in the fair value of derivative instruments, as measured using the three-level hierarchy described above, are recognized in “Other income (expense), net” in the Company’s Consolidated Statements of Operations.
	Financial assets and liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy, consisted of the following (in thousands), as of:
				March 31, 2015
				Fair Value Measurements
				Using Input Types
		Line Item		Level 1			Level 2				Level 3				Total

	Non-hedging derivative liabilities:
	Foreign currency forward contracts	Accounts payable and accrued expenses		$	0		$	6			$	0			$	6
	The fair value of our foreign currency forward contracts is determined using Level 2 observable market inputs to extrapolate forward points to be added to or subtracted from the closing market spot rate on the reporting date, and then discounted to present value. All foreign currency forward contracts outstanding as of March 31, 2015 were for durations of twelve months or less and consisted of the following sale contracts (in thousands):
		Notional Value							Notional Value				Fair Value

									$	17,400			$	2,590
	Changes in the fair value of our foreign currency forward contracts (in thousands) for the three months ended March 31, 2015 and 2014 were as follows:
		Gain (Loss) on Derivative Instruments Recognized in Income
				Three Months Ended

	Non-hedging derivative instruments:

	Realized loss on foreign currency forward contracts	Other income (expense), net		$	0		$	(255	)
	There were no transfers among the levels within the fair value hierarchy during each of the three months ended March 31, 2015 and 2014. As of March 31, 2015 and December 31, 2014, the Company had no assets or liabilities that were required to be measured at fair value on a non-recurring basis.
	The Company also estimates the fair value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, accrued compensation and employee benefits, and accrued restructuring costs. The Company considers the carrying value of these instruments in the financial statements to approximate fair value due to their short maturities.

Shortterm_Investments

Short-term Investments	3 Months Ended
	Mar. 31, 2015
Short-term Investments	(4) Short-term Investments
	The Company periodically invests a portion of its excess cash in short-term investment instruments. Substantially all of the Company’s short-term investments are in U.S. Treasury securities, and the Company has the ability and intent to hold these investments to maturity. The stated maturity dates of these investments are between three months and one year from the purchase date. These held-to-maturity investments are recorded at amortized cost and included within “Short-term investments” on the accompanying Consolidated Balance Sheets. The fair value of held-to-maturity investments in U.S. Treasury securities is determined based on quoted market prices in active markets for identical securities (Level 1 inputs).
	The amortized cost, carrying value, and fair value of held-to-maturity investments at March 31, 2015 were $226.6 million, $226.6 million, and $226.7 million, respectively. The amortized cost, carrying value, and fair value of held-to-maturity investments at December 31, 2014 were $198.5 million, $198.5 million, and $198.5 million, respectively. The gross unrecognized holding gains and losses were not material for the three months ended March 31, 2015 and 2014. No other-than-temporary impairments related to these investments have been recognized in accumulated other comprehensive loss as of March 31, 2015 and December 31, 2014. As of March 31, 2015 and December 31, 2014, the Company’s available-for-sale investments were not material.

	Less: allowance for doubtful accounts		(4,161	)		(4,412	)
	Accounts receivable, net	$	58,436		$	78,633
	The Company offsets its accounts receivable and deferred revenue for any unpaid items included in deferred revenue and advance payments.
	The Company maintains an allowance for doubtful accounts which represents its best estimate of probable losses inherent in the accounts receivable balances. The Company evaluates specific accounts when it becomes aware that a customer may not be able to meet its financial obligations due to deterioration of its liquidity or financial viability, credit ratings, or bankruptcy. In addition, the Company periodically adjusts this allowance based upon its review and assessment of the aging of receivables.

Restructuring

Restructuring	(6) Restructuring
	In September 2014, the Company committed to a restructuring plan (the “2014 Restructuring Plan”) to streamline its workforce and spending to better align its cost structure with its business strategy, including reducing the Company’s workforce by 777 employees, comprised of 217 employees in North America, 400 employees in Asia Pacific, 141 employees in Europe, the Middle East, and Africa, and 19 employees in Latin America. As of December 31, 2014, the Company had implemented substantially all of the 2014 Restructuring Plan. No material restructuring costs were incurred during the three months ended March 31, 2015. The Company does not expect future costs associated with implementing the remainder of the 2014 Restructuring Plan, consisting primarily of the liquidation of certain foreign subsidiaries, to be material.
	Costs associated with the 2014 Restructuring Plan include employee severance and related benefit costs (including outplacement services and continuing health insurance coverage), contract termination costs (including operating lease terminations for certain office space at the Company’s corporate headquarters and other international locations), and other charges (including external consulting and advisory fees related to implementing the restructuring plan). The following table summarizes the major types of costs associated with the 2014 Restructuring Plan (in thousands) for the three months ended March 31, 2015 and 2014, total costs incurred through March 31, 2015 and total costs expected to be incurred:

	Total restructuring costs	$	85	$	0	$	14,817		$	15,013
	The total restructuring costs above are reported as “Restructuring costs” under “Operating expenses” in the Company’s Consolidated Statements of Operations.
	Restructuring-related liabilities are reported as “Accrued restructuring costs” in the Company’s Consolidated Balance Sheets. The following table presents a summary of changes in the restructuring-related liabilities (in thousands) for the three months ended March 31, 2015:

	From time to time, the Company enters into certain types of contracts that require it to indemnify parties against third-party claims. These contracts primarily relate to agreements under which the Company has agreed to indemnify customers and partners for third-party claims arising from intellectual property infringement. The conditions of these obligations vary. Thus, the overall maximum amount of the Company’s indemnification obligations cannot be reasonably estimated. Historically, the Company has not been obligated to make significant payments for these obligations and does not currently expect to incur any material obligations in the future. Accordingly, the Company has not recorded an indemnification liability on its balance sheets as of March 31, 2015 or December 31, 2014.
	The Company leases office space and computer and other equipment under operating lease agreements. It also leases certain computer and other equipment under capital lease agreements and licenses certain software under other financing arrangements. Under the lease agreements, in addition to base rent, the Company is generally responsible for certain taxes, utilities and maintenance costs, and other fees; and several leases include options for renewal or purchase. As of December 31, 2014, the Company was leasing approximately 233,000 square feet of office space at a location in Northern Virginia that began serving as its corporate headquarters in October 2010. The Company gave written notice in August 2014 of its intent to terminate the lease with respect to 19,000 square feet of this office space, effective February 2015, as part of the 2014 Restructuring Plan. The Company never used the terminated lease space, and it remained vacant until it was terminated in February 2015. The term of the amended lease expires in December 2020.
	At March 31, 2015 and December 31, 2014, deferred rent of $18.1 million and $18.9 million, respectively, is included in other long-term liabilities, and $3.3 million and $3.0 million, respectively, is included in current accrued expenses.
	(b) Contingencies
	In December 2011, DataTern, Inc. (“DataTern”) filed a complaint for patent infringement against the Company in the United States District Court for the District of Massachusetts. The complaint alleged that the Company infringes U.S. Patent No. 6,101,502 (the “’502 Patent”), allegedly owned by DataTern, by making, selling, or offering for sale several of the Company’s products and services including MicroStrategy 9™, MicroStrategy Intelligence Server, MicroStrategy Business Intelligence Platform™, MicroStrategy Cloud Personal, and other MicroStrategy applications for creating or using data mining, dashboards, business analytics, data storage and warehousing, and Web hosting support. The complaint accused the Company of willful infringement and sought an unspecified amount of damages, an award of attorneys’ fees, and preliminary and permanent injunctive relief. In light of a judgment in a separate action involving DataTern in another jurisdiction, in February 2013, MicroStrategy and DataTern filed motions for summary judgment of non-infringement and the United States District Court for the District of Massachusetts entered summary judgment against DataTern. In March 2013, DataTern filed a notice of appeal with the United States Court of Appeals for the Federal Circuit (the “Federal Circuit”). In December 2014, the Federal Circuit issued an opinion vacating the District of Massachusetts’ summary judgment, stating that the claim construction on which the summary judgment was based was incorrect. In January 2015, the Federal Circuit ordered that the case be remanded for further proceedings, and in February 2015, the Company filed motions for summary judgment in the district court on grounds of non-infringement and invalidity. A hearing on the motions is scheduled for May 2015. The Company has received indemnification requests from certain of its resellers and customers who were sued by DataTern in the United States District Court for the District of Massachusetts in lawsuits alleging infringement of the ’502 Patent. The outcome of these matters is not presently determinable, and the Company cannot make a reasonable estimate of the possible loss or range of loss with respect to these matters at this time. Accordingly, no estimated liability for these matters has been accrued in the accompanying Consolidated Financial Statements.
	In December 2011, Vasudevan Software, Inc. (“Vasudevan”) filed a complaint for patent infringement against the Company in the United States District Court for the Northern District of California. The complaint alleged that the Company’s sale of MicroStrategy 9 and other MicroStrategy products infringes four patents allegedly owned by Vasudevan known as U.S. Patent Nos. 6,877,006, 7,167,864, 7,720,861, and 8,082,268, all entitled “Multimedia Inspection Database System for Dynamic Runtime Evaluation.” The complaint accused the Company of infringement, inducing others to infringe, and acts of contributory infringement with respect to the patents at issue and sought a permanent injunction, an unspecified amount of damages, and other relief as may be granted by the court. In October 2013, following a series of motions by the parties, the court dismissed the case, entered judgment of non-infringement based on a stipulation of non-infringement filed by Vasudevan, and also granted MicroStrategy’s motion for summary judgment of invalidity, finding the four patents in the suit invalid. In November 2013, Vasudevan filed a notice of appeal with the Federal Circuit. In April 2015, the Federal Circuit issued an opinion affirming the district court’s claim construction and judgment of non-infringement in favor of the Company, reversing the district court’s grants of summary judgment of invalidity, and ordering that the case be remanded to the district court for proceedings on the Company’s claim for declaratory judgment that the patents are invalid. The parties have until May 4, 2015 to petition the Federal Circuit for rehearing. The outcome of this matter is not presently determinable, and the Company cannot make a reasonable estimate of the possible loss or range of loss with respect to this matter at this time. Accordingly, no estimated liability for this matter has been accrued in the accompanying Consolidated Financial Statements.
	The Company is also involved in various other legal proceedings arising in the normal course of business. Although the outcomes of these other legal proceedings are inherently difficult to predict, management does not expect the resolution of these other legal proceedings to have a material adverse effect on the Company’s financial position, results of operations, or cash flows.
	The Company has contingent liabilities that, in management’s judgment, are not probable of assertion. If such unasserted contingent liabilities were to be asserted, or become probable of assertion, the Company may be required to record significant expenses and liabilities in the period in which these liabilities are asserted or become probable of assertion.

	The Board of Directors has authorized the Company’s repurchase of up to an aggregate of $800.0 million of its class A common stock from time to time on the open market through April 29, 2018 (the “2005 Share Repurchase Program”), although the program may be suspended or discontinued by the Company at any time. The timing and amount of any shares repurchased will be determined by the Company’s management based on its evaluation of market conditions and other factors. The 2005 Share Repurchase Program may be funded using the Company’s working capital, as well as proceeds from any other funding arrangements that the Company may enter into in the future. During each of the three months ended March 31, 2015 and 2014, the Company did not repurchase any shares of its class A common stock pursuant to the 2005 Share Repurchase Program. As of March 31, 2015, the Company had repurchased an aggregate of 3,826,947 shares of its class A common stock at an average price per share of $90.23 and an aggregate cost of $345.3 million. The average price per share and aggregate cost amounts disclosed above include broker commissions.

Income Taxes	(10) Income Taxes
	The Company and its subsidiaries conduct business in the U.S. and various foreign countries and are subject to taxation in numerous domestic and foreign jurisdictions. As a result of its business activities, the Company files tax returns that are subject to examination by various federal, state and local, and foreign tax authorities. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or foreign income tax examination by tax authorities for years before 2011. However, due to its use of state net operating loss (“NOL”) and federal tax credit carryovers in the U.S., U.S. tax authorities may attempt to reduce or fully offset the amount of state NOL or federal tax credit carryovers from tax years ended in 2007 and forward that were used in later tax years. The Company’s major foreign tax jurisdictions and tax years that remain subject to examination are Germany for tax years 2013 forward, Poland and China for tax years 2010 forward, Spain for tax years 2011 forward, and the United Kingdom for tax years 2013 forward. The Company settled a tax examination in Germany for years 2009 to 2012 in the first quarter of 2015 without a material assessment. The Company is currently under tax examination in the United States for tax years 2011 and 2012. To date, these audits have not resulted in any material assessments.
	As of March 31, 2015, the Company had unrecognized tax benefits of $2.7 million, which are recorded in other long-term liabilities. If recognized, $1.9 million of these unrecognized tax benefits would impact the effective tax rate. The Company recognizes estimated accrued interest related to unrecognized income tax benefits in the provision for income tax accounts. Penalties relating to income taxes, if incurred, would also be recognized as a component of the Company’s provision for income taxes. Over the next 12 months, the amount of the Company’s liability for unrecognized tax benefits is not expected to change by a material amount. As of March 31, 2015, the amount of cumulative accrued interest expense on unrecognized income tax benefits was approximately $0.4 million.
	The following table summarizes the Company’s deferred tax assets, net of deferred tax liabilities and valuation allowance (in thousands), as of:
		March 31,			December 31,
		2015			2014
	Deferred tax assets, net of deferred tax liabilities	$	14,707		$	19,321
	Valuation allowance		(2,332	)		(2,311	)
	Deferred tax assets, net of deferred tax liabilities and valuation allowance	$	12,375		$	17,010
	The valuation allowance as of March 31, 2015 and December 31, 2014 primarily relates to certain foreign net operating loss carryforward and foreign tax credit carryforward tax assets. The Company has determined that there is insufficient positive evidence that it is more likely than not that such deferred tax assets will be realized.
	The Company has estimated its annual effective tax rate for the full fiscal year 2015 and applied that rate to its income before income taxes in determining its provision for income taxes for the three months ended March 31, 2015. The Company also records discrete items in each respective period as appropriate. The estimated effective tax rate is subject to fluctuation based upon the level and mix of earnings and losses by tax jurisdiction, foreign tax rate differentials, and the relative impact of permanent book to tax differences (e.g., non-deductible expenses). Each quarter, a cumulative adjustment is recorded for any fluctuations in the estimated annual effective tax rate as compared to the prior quarter. As a result of these factors, and due to potential changes in the Company’s period to period results, fluctuations in the Company’s effective tax rate and respective tax provisions or benefits may occur.
	For the three months ended March 31, 2015, the Company recorded a provision for income taxes of $6.9 million that resulted in an effective tax rate of 25.3%, as compared to a benefit from income taxes of $2.9 million that resulted in an effective tax rate of 31.2% for the three months ended March 31, 2014. The change in the effective tax rate in 2015 is mainly due to changes in the forecasted overall income or loss amounts for 2015 and a change in the expected proportion of U.S. versus foreign income.
	Except as discussed below, the Company intends to indefinitely reinvest its undistributed earnings of all of its foreign subsidiaries. Therefore, the annualized effective tax rate applied to the Company’s pre-tax income does not include any provision for U.S. federal and state income taxes on the amount of the undistributed foreign earnings. U.S. federal tax laws, however, require the Company to include in its U.S. taxable income certain investment income earned outside of the U.S. in excess of certain limits (“Subpart F deemed dividends”). Because Subpart F deemed dividends are already required to be recognized in the Company’s U.S. federal income tax return, the Company regularly repatriates Subpart F deemed dividends to the U.S. and no additional tax is incurred on the distribution. As of March 31, 2015 and December 31, 2014, the amount of cash and cash equivalents and short-term investments held by U.S. entities was $160.4 million and $139.1 million, respectively, and by non-U.S. entities was $231.4 million and $206.4 million, respectively. If the cash and cash equivalents and short-term investments held by non-U.S. entities were to be repatriated to the U.S., the Company would generate U.S. taxable income to the extent of the Company’s undistributed foreign earnings, which amounted to $201.7 million at December 31, 2014. Although the tax impact of repatriating these earnings is difficult to determine, the Company would not expect the maximum effective tax rate that would be applicable to such repatriation to exceed the U.S. statutory rate of 35.0%, after considering applicable foreign tax credits.
	In determining the Company’s provision or benefit for income taxes, net deferred tax assets, liabilities, and valuation allowances, management is required to make judgments and estimates related to projections of domestic and foreign profitability, the timing and extent of the utilization of net operating loss carryforwards, applicable tax rates, transfer pricing methods, and prudent and feasible tax planning strategies. As a multinational company, the Company is required to calculate and provide for estimated income tax liabilities for each of the tax jurisdictions in which it operates. This process involves estimating current tax obligations and exposures in each jurisdiction, as well as making judgments regarding the future recoverability of deferred tax assets. Changes in the estimated level of annual pre-tax income, changes in tax laws, particularly changes related to the utilization of net operating losses in various jurisdictions, and changes resulting from tax audits can all affect the overall effective income tax rate which, in turn, impacts the overall level of income tax expense or benefit and net income.
	Judgments and estimates related to the Company’s projections and assumptions are inherently uncertain; therefore, actual results could differ materially from projections. The timing and manner in which the Company will use net operating loss carryforward tax assets, research and development tax credit carryforward tax assets, alternative minimum tax credit carryforward tax assets, and foreign tax credit carryforward tax assets in any year, or in total, may be limited by provisions of the Internal Revenue Code regarding changes in the Company’s ownership. Currently, the Company expects to use the tax assets, subject to Internal Revenue Code limitations, within the carryforward periods. Valuation allowances have been established where the Company has concluded that it is more likely than not that such deferred tax assets are not realizable. If the Company is unable to sustain profitability in future periods, it may be required to increase the valuation allowance against the deferred tax assets, which could result in a charge that would materially adversely affect net income in the period in which the charge is incurred.

	In September 2013, the Board of Directors approved the Company’s 2013 Stock Incentive Plan (the “original 2013 Equity Plan”, and, as amended, the “2013 Equity Plan”), under which the Company’s employees, officers, directors, and other eligible participants may be awarded various types of share-based compensation, and authorized 600,000 shares of the Company’s class A common stock for issuance under the original 2013 Equity Plan. In April 2014, the Company’s stockholders approved the original 2013 Equity Plan.
	In April 2014, following stockholder approval of the original 2013 Equity Plan, the Board of Directors authorized, subject to stockholder approval, an amendment to the original 2013 Equity Plan to increase the total number of shares of the Company’s class A common stock authorized for issuance under the 2013 Equity Plan from 600,000 to 1,500,000 shares (“Amendment No. 1”). Also in April 2014, the Compensation Committee of the Board of Directors (the “Compensation Committee”) authorized, subject to stockholder approval, an additional amendment to the original 2013 Equity Plan to provide for automatic annual stock option grants to each of the Company’s non-employee directors with respect to 5,000 shares of the Company’s class A common stock, beginning in May 2015 (“Amendment No. 2”).
	During 2014 and the first quarter of 2015, the Compensation Committee approved, in each case subject to stockholder approval of Amendment No. 1, the grant of stock options to purchase an aggregate of 745,000 and 200,000 shares of class A common stock, respectively, to certain Company employees, officers, and directors pursuant to the 2013 Equity Plan. In April 2015, the Company’s stockholders approved Amendments No. 1 and 2 at the Company’s annual meeting. As of March 31, 2015, and taking into account the shares authorized and options granted subject to approval of Amendments No. 1 and 2, there were options to purchase 1,335,000 shares of class A common stock outstanding under the 2013 Equity Plan and 140,000 remaining shares of class A common stock authorized for issuance and not subject to outstanding awards under the 2013 Equity Plan.

	Total		1,335		$	119.39		8.2
	No stock options vested during the three months ended March 31, 2015. The Company expects the majority of unvested options at March 31, 2015 to fully vest in future years in accordance with their vesting schedules. Share-based compensation expense has been adjusted, where applicable, for any expected forfeitures. The weighted average grant date fair value of stock option awards using the Black-Scholes pricing model was $68.19 for each share subject to a stock option granted during the three months ended March 31, 2015, based on the following assumptions:
		Three months ended
		March 31,
		2015
	Expected term of options in years		6.3
	Expected volatility		40.2	%
	Risk-free interest rate		1.5	%
	Expected dividend yield		0	%
	No stock option awards were granted during the three months ended March 31, 2014.
	For the three months ended March 31, 2015 and 2014, the Company recognized approximately $3.6 million and $1.6 million, respectively, in share-based compensation expense from stock options granted under the 2013 Equity Plan. As of March 31, 2015, there was approximately $49.7 million of total unrecognized share-based compensation expense related to unvested stock options. The Company expects to recognize this remaining share-based compensation expense over a weighted average vesting period of approximately 3.1 years.
	During the three months ended March 31, 2015, the Company was able to recognize and utilize net operating loss carryforwards arising directly from tax deductions related to equity compensation in excess of compensation recognized for financial reporting that was generated under the 2013 Equity Plan. Accordingly, stockholders’ equity increased by $0.5 million during the three months ended March 31, 2015. During the three months ended March 31, 2014, no windfall tax benefits were realized from the exercise of stock options.

Common Equity and Earnings per Share	(12) Common Equity and Earnings per Share
	The Company has two classes of common stock: class A common stock and class B common stock. Holders of class A common stock generally have the same rights, including rights to dividends, as holders of class B common stock, except that holders of class A common stock have one vote per share while holders of class B common stock have ten votes per share. Each share of class B common stock is convertible at any time, at the option of the holder, into one share of class A common stock. As such, basic and fully diluted earnings per share for class A common stock and for class B common stock are the same. The Company has never declared or paid any cash dividends on either class A or class B common stock. As of March 31, 2015 and December 31, 2014, there were no shares of preferred stock issued or outstanding.
	Potential shares of common stock are included in the diluted earnings per share calculation when dilutive. Potential shares of common stock, consisting of common stock issuable upon exercise of outstanding stock options, are calculated using the treasury stock method. For the three months ended March 31, 2015, stock options issued under the 2013 Equity Plan to purchase an aggregate of 285,000 shares of common stock were excluded from the diluted earnings per share calculation because their impact would have been anti-dilutive. For the three months ended March 31, 2014, stock options issued under the 2013 Equity Plan to purchase an aggregate of 600,000 shares of class A common stock were excluded from the diluted earnings per share calculation because their impact would have been anti-dilutive.

Basis of Presentation	(a) Basis of Presentation
	Except for the Consolidated Balance Sheet of MicroStrategy Incorporated (“MicroStrategy” or the “Company”) as of December 31, 2014, which was derived from audited financial statements, the accompanying Consolidated Financial Statements are unaudited. In the opinion of management, all adjustments necessary for a fair statement of such financial position and results of operations have been included. All such adjustments are of a normal recurring nature unless otherwise disclosed. Interim results are not necessarily indicative of results for a full year.
	Certain amounts in the prior year’s Consolidated Financial Statements and Notes to Consolidated Financial Statements have been reclassified to conform to current year presentation. Revenues and cost of revenues have been reclassified in the Consolidated Statements of Operations to reflect the separate components of total product licenses and subscription services, and unrealized gains and losses on foreign currency forward contracts have been reclassified within the operating section in the Consolidated Statements of Cash Flows.
	The Consolidated Financial Statements and Notes to Consolidated Financial Statements are presented as required by the United States Securities and Exchange Commission (“SEC”) and do not contain certain information included in the Company’s annual financial statements and notes. These financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto filed with the SEC in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. There have been no significant changes in the Company’s accounting policies since December 31, 2014.
	The accompanying Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Fair Value Measurements	The Company measures certain assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that is expected to be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a three-level hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. The three levels of the fair value hierarchy are described below:
		Level 1:	Quoted (unadjusted) prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
		Level 2:	Inputs other than quoted prices that are either directly or indirectly observable, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		Level 3:	Inputs that are generally unobservable, supported by little or no market activity, and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability.
	The categorization of an asset or liability within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The valuation techniques used by the Company when measuring fair value maximize the use of observable inputs and minimize the use of unobservable inputs.
	The Company also estimates the fair value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, accrued compensation and employee benefits, and accrued restructuring costs. The Company considers the carrying value of these instruments in the financial statements to approximate fair value due to their short maturities.
Derivative Financial Instruments	The Company is exposed to certain risks related to its ongoing business operations, including the effect of changes in foreign exchange rates on the Company’s monetary assets and liabilities denominated in foreign currency. The Company uses foreign currency forward contracts as part of its strategy to manage these risks, but does not hold or issue derivative instruments for trading purposes or speculation. The Company executes these instruments with financial institutions that hold an investment grade credit rating. These foreign currency forward contracts do not meet the requirements for hedge accounting and are recorded on the balance sheet as either an asset or liability measured at their fair value as of the reporting date. Changes in the fair value of derivative instruments, as measured using the three-level hierarchy described above, are recognized in “Other income (expense), net” in the Company’s Consolidated Statements of Operations.
Short-term investments	The Company periodically invests a portion of its excess cash in short-term investment instruments. Substantially all of the Company’s short-term investments are in U.S. Treasury securities, and the Company has the ability and intent to hold these investments to maturity. The stated maturity dates of these investments are between three months and one year from the purchase date. These held-to-maturity investments are recorded at amortized cost and included within “Short-term investments” on the accompanying Consolidated Balance Sheets. The fair value of held-to-maturity investments in U.S. Treasury securities is determined based on quoted market prices in active markets for identical securities (Level 1 inputs).
Income taxes	The Company recognizes estimated accrued interest related to unrecognized income tax benefits in the provision for income tax accounts.
	In determining the Company’s provision or benefit for income taxes, net deferred tax assets, liabilities, and valuation allowances, management is required to make judgments and estimates related to projections of domestic and foreign profitability, the timing and extent of the utilization of net operating loss carryforwards, applicable tax rates, transfer pricing methods, and prudent and feasible tax planning strategies. As a multinational company, the Company is required to calculate and provide for estimated income tax liabilities for each of the tax jurisdictions in which it operates. This process involves estimating current tax obligations and exposures in each jurisdiction, as well as making judgments regarding the future recoverability of deferred tax assets. Changes in the estimated level of annual pre-tax income, changes in tax laws, particularly changes related to the utilization of net operating losses in various jurisdictions, and changes resulting from tax audits can all affect the overall effective income tax rate which, in turn, impacts the overall level of income tax expense or benefit and net income.
	Judgments and estimates related to the Company’s projections and assumptions are inherently uncertain; therefore, actual results could differ materially from projections. The timing and manner in which the Company will use net operating loss carryforward tax assets, research and development tax credit carryforward tax assets, alternative minimum tax credit carryforward tax assets, and foreign tax credit carryforward tax assets in any year, or in total, may be limited by provisions of the Internal Revenue Code regarding changes in the Company’s ownership. Currently, the Company expects to use the tax assets, subject to Internal Revenue Code limitations, within the carryforward periods. Valuation allowances have been established where the Company has concluded that it is more likely than not that such deferred tax assets are not realizable. If the Company is unable to sustain profitability in future periods, it may be required to increase the valuation allowance against the deferred tax assets, which could result in a charge that would materially adversely affect net income in the period in which the charge is incurred.
Basic and Diluted Earnings per share	Potential shares of common stock are included in the diluted earnings per share calculation when dilutive. Potential shares of common stock, consisting of common stock issuable upon exercise of outstanding stock options, are calculated using the treasury stock method.
