Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2017

(a)	Basis of Presentation

Except for the Consolidated Balance Sheet of MicroStrategy Incorporated (“MicroStrategy” or the “Company”) as of December 31, 2016, 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 have been reclassified to conform to current year presentation. Changes in restricted cash have been removed from investing activities in the Consolidated Statements of Cash Flows; instead, restricted cash has been included with total cash and cash equivalents when reconciling the beginning and end of period amounts, as discussed in Note 2, Recent Accounting Standards, to the Consolidated Financial Statements.

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, 2016. There have been no significant changes in the Company’s accounting policies since December 31, 2016, except as discussed in Note 2, Recent Accounting Standards, to the Consolidated Financial Statements.

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. The Company is not aware of any subsequent event which would require recognition or disclosure.

Fair Value Measurements

The Company estimates the fair value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, and accrued compensation and employee benefits. The Company considers the carrying value of these instruments in the financial statements to approximate fair value due to their short maturities.

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 certificates of deposit, 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 and certificates of deposit 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 NOL 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 NOLs 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 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 these 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.

Share-based Compensation

Beginning January 1, 2017, the Company made an accounting policy election to prospectively account for forfeitures as they occur. Therefore, share-based compensation expense has not been adjusted for any estimated forfeitures.

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.
