Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements of BSQUARE Corporation (“BSQUARE”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting and include the accounts of BSQUARE and our wholly owned subsidiaries. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, the unaudited condensed consolidated financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly our financial position as of June 30, 2016, our operating results for the three and six months ended June 30, 2016 and 2015 and our cash flows for the six months ended June 30, 2016 and 2015. The accompanying financial information as of December 31, 2015 is derived from audited financial statements. Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Examples include provisions for bad debts and income taxes, estimates of progress on professional engineering service arrangements and bonus accruals. Actual results may differ from these estimates. Interim results are not necessarily indicative of results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2015. All intercompany balances have been eliminated. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” amending revenue recognition guidance and requiring more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The guidance, as amended, is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted for public companies effective for annual and interim reporting periods beginning after December 15, 2016. We are currently evaluating the impact this ASU will have on our consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes,” to simplify the presentation of deferred income taxes. The amendments in this ASU require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this ASU apply to all entities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this ASU. We adopted the new guidance retrospectively beginning with the year ended December 31, 2014, and applied such guidance consistently for the year ended December 31, 2015. In February 2016, the FASB issued ASU No. 2016-2, “Leases,” to make leasing activities more transparent and comparable, requiring most leases be recognized by lessees on their balance sheets as right-of-use assets, along with corresponding lease liabilities. ASU 2016-2 is effective for public business entities for annual periods beginning after December 31, 2018 and interim periods within that year, with early adoption permitted. We are currently evaluating the impact this ASU may have on our consolidated financial statements and related disclosures. In March 2016, the FASB amended the existing accounting standards for stock-based compensation, ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments impact several aspects of accounting for share-based payment transactions, including income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. We are required to adopt the amendments in the first quarter of 2017, with early adoption permitted. If early adoption is elected, all amendments must be adopted in the same period. The manner of application varies by the various provisions of the guidance, with certain provisions applied on a retrospective or modified retrospective approach, while others are applied prospectively. We are currently evaluating the impact of these amendments and the transition alternatives on our consolidated financial statements and related disclosures. Income (Loss) Per Share Basic income (loss) per share is computed using the weighted average number of common shares outstanding during the period, and excludes any dilutive effects of common stock equivalent shares, such as options, restricted stock awards and restricted stock units. Restricted stock awards (“RSAs”) are considered outstanding and included in the computation of basic income or loss per share when underlying restrictions expire and the awards are no longer forfeitable. Restricted stock units (“RSUs”) are considered outstanding and included in the computation of basic income or loss per share only when vested. Diluted income (loss) per share is computed using the weighted average number of common shares outstanding and common stock equivalent shares outstanding during the period using the treasury stock method. Common stock equivalent shares are excluded from the computation if their effect is anti-dilutive. We excluded an aggregate of 1,864,147 and 654,441 options for the three and six months ended June 30, 2016, respectively, from diluted earnings per share because their effect was anti-dilutive. For the three months ended June 30, 2016, this included common stock equivalent shares of 1,188,189 calculated using the treasury stock method that would have been included in diluted earnings per share had we been in a net income position. In a period where we are in a loss position, diluted loss per share is computed using the basic share count. We excluded an aggregate of 114,270 and 130,159 options for the three and six months ended June 30, 2015, respectively, from diluted earnings per share because their effect was anti-dilutive.

Income (Loss) Per Share

Basic income (loss) per share is computed using the weighted average number of common shares outstanding during the period, and excludes any dilutive effects of common stock equivalent shares, such as options, restricted stock awards and restricted stock units. Restricted stock awards (“RSAs”) are considered outstanding and included in the computation of basic income or loss per share when underlying restrictions expire and the awards are no longer forfeitable. Restricted stock units (“RSUs”) are considered outstanding and included in the computation of basic income or loss per share only when vested. Diluted income (loss) per share is computed using the weighted average number of common shares outstanding and common stock equivalent shares outstanding during the period using the treasury stock method. Common stock equivalent shares are excluded from the computation if their effect is anti-dilutive.

We excluded an aggregate of 1,864,147 and 654,441 options for the three and six months ended June 30, 2016, respectively, from diluted earnings per share because their effect was anti-dilutive. For the three months ended June 30, 2016, this included common stock equivalent shares of 1,188,189 calculated using the treasury stock method that would have been included in diluted earnings per share had we been in a net income position. In a period where we are in a loss position, diluted loss per share is computed using the basic share count. We excluded an aggregate of 114,270 and 130,159 options for the three and six months ended June 30, 2015, respectively, from diluted earnings per share because their effect was anti-dilutive.
