	1. Organization and business
	(a) Description of business
	Imprivata, Inc. (the “Company”) provides authentication and access management technology solutions primarily for the healthcare industry. The Company’s flagship product Imprivata OneSign, is an integrated enterprise single sign-on, authentication management and workflow automation platform that addresses multiple security and productivity challenges faced by hospitals and other healthcare organizations. By enabling fast, secure access to healthcare information technology systems, the Company believes that its solutions save clinicians significant time to focus on patient care, increase their productivity and satisfaction, and help healthcare organizations comply with privacy and security regulations.
	The Company was incorporated in the State of Delaware in May 2001.
	(b) Initial public offering
	On June 30, 2014, the Company completed an initial public offering (“IPO”), in which it sold 5,750,000 shares of common stock, including 750,000 shares sold pursuant to the underwriters’ option to purchase additional shares, at an offering price of $15.00 per share. All outstanding shares of the Company’s redeemable convertible preferred stock converted to 13,970,934 shares of common stock at the closing of the IPO. The Company’s shares are traded on the New York Stock Exchange (“NYSE”) under the symbol “IMPR”. The Company received proceeds from the IPO of $80.2 million, net of underwriting discounts and commissions, but before offering expenses of approximately $3.3 million. Offering expenses at December 31, 2013 of $0.5 million were recorded as other noncurrent assets. These offering expenses, and additional expenses incurred from January 2014 through the closing of the IPO of approximately $2.8 million, have been recorded as a reduction of the proceeds received.
	(c) Basis of presentation and principles of consolidation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) applicable to interim periods, under the rules and regulations of the United States Securities and Exchange Commission (“SEC”), and on a basis substantially consistent with the audited consolidated financial statements of the Company as of and for the fiscal year ended December 31, 2013. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for the fair statement have been included. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, for any other interim period or for any other future year.
	The consolidated balance sheet at December 31, 2013 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s prospectus filed with the SEC on June 24, 2014 pursuant to Rule 424(b) under the Securities Act of 1933, as amended.
	The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Imprivata International Limited, and its wholly owned subsidiary Imprivata UK Limited. All intercompany balances and transactions have been eliminated in consolidation.
	(d) Stock Split
	In May 2014, the Company’s Board of Directors approved a 1-for-1.5 reverse stock split of the Company’s common stock. The reverse stock split became effective on May 30, 2014. Upon the effectiveness of the reverse stock split, (i) every 1.5 shares of outstanding common stock was combined into one share of common stock, (ii) the number of shares of common stock into which each outstanding warrant or option to purchase common stock is exercisable was proportionally decreased, (iii) the exercise price of each outstanding warrant or option to purchase common stock was proportionately increased, and (iv) the conversion ratio for each share of preferred stock outstanding was proportionately reduced. Unless otherwise indicated, all of the share numbers, share prices and exercise prices in these financial statements have been adjusted, on a retroactive basis, to reflect this 1-for-1.5 reverse stock split.

	2. Summary of significant accounting policies
	The Company has not made any significant changes in the application of its significant accounting policies as described in the accompanying notes to the consolidated financial statements contained in the Company’s prospectus filed with the Securities and Exchange Commission (“SEC”) on June 24, 2014 pursuant to Rule 424(b) under the Securities Act of 1933, as amended.
	Jumpstart Our Business Startups (“JOBS”) Act
	Under the JOBS Act, the Company meets the definition of an emerging growth company. The Company has irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.
	Accounting standards or updates recently adopted
	Effective January 1, 2014, the Company adopted Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of a Liability for an Unrecognized Tax Benefit When a Net Operating Loss or Tax Credit”. The new guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The adoption of this update did not have a significant impact on the Company’s consolidated financial statements, as it required only enhanced disclosures.
	Accounting standards or updates not yet effective
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606) (ASU 2014-09). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016; early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. This update could impact the timing and amounts of revenue recognized. The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption.

Fair Value Disclosures [Abstract]	'
Fair value measurements	'
	3. Fair value measurements
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
	(a) Fair value hierarchy
	The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:
	Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.
	Level 2 applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.
	Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.
	(b) Assets and liabilities measured at fair value on a recurring basis
	The Company’s cash equivalents consist of money market funds recorded at cost, which approximates fair value measured based on quoted prices for similar assets traded in active markets. The contingent consideration liability is recorded at fair value determined using a probability weighted discounted cash flow model primarily based upon future revenue projections in active markets.
	The following table sets forth the Company’s assets and liabilities which are measured at fair value on a recurring basis by level within the fair value hierarchy:
			June 30, 2014 fair value measurements

	Liabilities
	Contingent consideration		$	—		$	—		$	1,008	$	1,008
	(c) Assets and liabilities measured on a non-recurring basis
	There were no fair value measurements on a non-recurring basis as of June 30, 2014 and December 31, 2013.
	(d) Level 3 fair value measurements
	The contingent liability associated with the acquisition of Validus is based on an earn-out capped at $9.8 million, to be paid based on revenue generated using the purchased intellectual property.
	The Company re-measures the fair value of the contingent liability at each balance sheet date based on the present value of forecasted revenues through December 31, 2016. The changes in the fair value are primarily due to the difference in actual revenue earned to date versus the initial projections and revisions to the timing and amount of forecasted future revenues.
	The resulting forecasted revenues were then discounted using a rate that reflects the uncertainty surrounding the expected outcomes, which the Company believes is appropriate and representative of a market participant assumption.
	The following table presents a reconciliation of the contingent liability measured at fair value using significant unobservable inputs, and the revaluation amount recorded in the Company’s consolidated statements of operations as a result of the change in fair value:
	(in thousands)		June 30,			December 31,
			2014			2013
	Beginning balance		$	1,008		$	1,885
	Revaluation recognized in general and administrative expenses in the corresponding statements of operations			(464	)		(877	)
	Ending balance		$	544		$	1,008
	The following table presents the significant unobservable inputs used in the valuation of the contingent liability:
			June 30,			December 31,
			2014			2013
	Discount Rate			17	%		17%—23%(1	)
	-1	The weighted-average discount rate for the year ended December 31, 2013 was 20%.
	(e) Other financial instruments
	The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents (which are comprised primarily of deposit accounts), accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses approximate fair value due to their short-term maturities.

	6. Debt
	(a) Bank credit facility
	The Company has a revolving credit facility with a bank pursuant to a Loan and Security Agreement dated January 30, 2009 (the “Revolving Credit Facility”). In February 2014, the Company modified the revolving credit agreement which had expired in October 2013. The modified Revolving Credit Facility provides for borrowings of up to $10.0 million based primarily on accounts receivable, and is subject to certain financial covenants requiring the Company to maintain minimum levels of liquidity. The credit facility matures in February 2015. Outstanding borrowings accrue interest at the Wall Street Journal published prime rate plus 0.75%. Substantially all of the assets of the Company are pledged as collateral.
	As of June 30, 2014, there was no balance outstanding under the revolving credit facility.
	(b) Term loans
	During the six months ended June 30, 2014, the Company entered into a $387,000 thirty month term loan for prepaid software licenses and associated maintenance with a 6.5% interest rate.
	(c) Capital leases
	During the six months ended June 30, 2014, the Company entered into three capital leases for information technology and office equipment totaling approximately $690,000. The capital lease arrangements have three year terms and bear interest at interest rates between 3.0% and 5.5%.

	(a) Litigation
	The Company is not presently a party to any litigation that it believes might have a material adverse effect on its business operations or financial statements.
	(b) Indemnifications
	As permitted under Delaware law, the Company’s Certificate of Incorporation, By Laws and director and officer agreements provide that the Company indemnify its stockholders, officers, directors, and partners, and each person controlling the stock held for certain events or occurrences that happen by reason of the relationship with or position held at the Company. The Company’s agreements with customers generally require the Company to indemnify the customer against claims in which the Company’s products infringe third-party patents, copyrights, or trademarks, and indemnify against product liability matters.
	As of June 30, 2014 and December 31, 2013, the Company had not experienced any material losses related to these indemnification obligations, and no material claims with respect thereto were outstanding. The Company does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible, and no related reserves were established.

	10. Stock award plans and stock based compensation
	(a) Equity incentive plan
	In May 2014, the Company’s 2014 Stock Option and Incentive Plan (“2014 Plan”), was adopted by the Company’s board of directors and approved by its stockholders and became effective in June 2014. The 2014 Plan replaces the Amended and Restated 2002 Stock Option and Incentive Plan (“2002 Plan”) as the Company’s board of directors has determined not to make additional awards under the 2002 Plan. The 2014 Plan allows the compensation committee to make equity-based incentive awards to the Company’s officers, employees, directors and other key persons (including consultants).
	Stock options expire no later than 10 years from the date of grant and generally vest over a period of four years. At the discretion of the Board of Directors, certain option grants may be immediately exercisable but subject to a right to repurchase, at cost, pursuant to the vesting schedule of the individual grant.
	At June 30, 2014, there were 2,452,907 shares available for future grant under the 2014 Plan.
	(b) Employee stock purchase plan
	In May 2014, the Company’s board of directors adopted and its stockholders approved the Employee Stock Purchase Plan (“ESPP”). Each employee who is a participant in the ESPP may purchase shares by authorizing payroll deductions of his or her base compensation during an offering period. Unless the participating employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to purchase ordinary shares on the last business day of the offering period at a price equal to 85% of the fair market value of the common stock on the first business day or the last business day of the offering period, whichever is lower.
	At June 30, 2014, there were 448,000 shares available for future grant under the ESPP.
	(c) Early exercise of stock options
	At June 30, 2014 and December 31, 2013, a total of 51,454 and 62,706 shares of unvested stock options exercised were subject to repurchase at an aggregate price of approximately $230,000 and $275,000, respectively. These amounts are recorded as accrued and other current liabilities in the Company’s consolidated balance sheets and will be reclassified to equity as the Company’s repurchase right lapses.
	(d) Valuation of employee stock options
	The Company utilizes the Black-Scholes option-pricing model to estimate the fair value of stock options awarded to employees, which requires several key assumptions to be made.
	Weighted average assumptions used to apply this model were as follows:
			Three months ended						Six months ended
			June 30,						June 30,
			2014			2013			2014			2013
	Risk-free interest rate(1)			1.93	%		0.91	%		1.91	%		1	%
	Expected life (years)(2)			6.03			6.03			6.04			6.04
	Expected dividend yield(3)			—	%		—	%		—	%		—	%
	Expected volatility of underlying stock(4)			54.99	%		45.35	%		54.76	%		45.44	%
	-1	Risk-free interest rate—the yield on zero-coupon U.S. Treasury securities with maturities similar to the expected term of the award being valued is used as the risk-free interest rate.
	-2	Expected term—the expected term for stock options granted based on a review of the period that the Company’s stock option awards are expected to be outstanding and is calculated using the simplified method, which represents the average of the contractual term of the options and the weighted-average vesting period of the options. The Company uses the simplified method because it does not have sufficient historical option exercise data to provide a reasonable basis upon which to estimate the expected term.
	-3	Expected dividend yield—the expected dividend yield was not considered in the option pricing formula since the Company has not declared dividends and does not expect to pay dividends in the foreseeable future.
	-4	Expected volatility—the Company is responsible for estimating volatility. The Company has been a private company and does not have relevant historical data to develop its volatility assumptions and, therefore, analyzed the volatility of several public peer companies to support the assumptions used in its calculations for the periods presented.
	(d) Summary of share-based compensation expense
	Share-based compensation expense is measured at the grant date, based on the calculated fair value of the award. The Company uses the straight-line attribution method to recognize expense for stock-based awards such that the expense associated with awards is evenly recognized throughout the requisite service period, which is generally the vesting period of four years. The Company estimates forfeitures at the time of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
	The following table presents stock-based compensation expense included in the Company’s consolidated statements of comprehensive income:
			Three months ended						Six months ended

	11. Income taxes
	Income tax expense relates principally to operating results of foreign entities, primarily in Europe, where the Company earns taxable income. The Company has significant net operating losses in the United States and, as a result, does not pay significant income taxes.
	As of December 31, 2013, the Company’s valuation allowance related to income taxes was approximately $21.4 million. The Company is in a three year cumulative loss position in the United States. As a result, the Company maintains a 100% valuation allowance to reduce the carrying value of the related deferred tax assets to zero. The Company will continue to maintain a full valuation allowance for those tax assets until sustainable future levels of profitability are evident.
	As of June 30, 2014 and December 31, 2013, the Company had no uncertain positions or unrecorded liabilities for uncertain tax positions.

	12. Computation of net loss per share
	The Company calculates basic and diluted net loss per common share by dividing the net loss adjusted for the accretion on the redeemable convertible preferred stock by the weighted average number of common shares outstanding during the period. The Company has excluded all potentially dilutive shares, which include redeemable convertible preferred stock, warrant for common stock, common stock subject to repurchase and outstanding common stock options, from the weighted average number of common shares outstanding as their inclusion in the computation for all periods would be anti-dilutive due to net losses. The Company’s redeemable convertible preferred stock are participating securities as defined under the authoritative guidance, but are excluded from the earnings per share calculation as they do not have an obligation to share or fund in the Company’s net losses.
	The components of net loss per share are as follows:

	In May 2014, the Company’s Board of Directors approved a 1-for-1.5 reverse stock split of the Company’s common stock. The reverse stock split became effective on May 30, 2014. Upon the effectiveness of the reverse stock split, (i) every 1.5 shares of outstanding common stock was combined into one share of common stock, (ii) the number of shares of common stock into which each outstanding warrant or option to purchase common stock is exercisable was proportionally decreased, (iii) the exercise price of each outstanding warrant or option to purchase common stock was proportionately increased, and (iv) the conversion ratio for each share of preferred stock outstanding was proportionately reduced. Unless otherwise indicated, all of the share numbers, share prices and exercise prices in these financial statements have been adjusted, on a retroactive basis, to reflect this 1-for-1.5 reverse stock split.

The new guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The adoption of this update did not have a significant impact on the Company’s consolidated financial statements, as it required only enhanced disclosures.
