Organization Consolidation And Presentation Of Financial Statements [Abstract]
Liquidity And Going Concern	Liquidity and Going Concern The Company adopted FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40) effective December 31, 2016, which requires the Company to make certain disclosures if it concludes that there is substantial doubt about the entity’s ability to continue as a going concern within one year from the date of the issuance of these financial statements. The Company has incurred significant losses and negative cash flows from operations since its inception and had an accumulated deficit of $212.6 million at December 31, 2016. As of December 31, 2016, the Company had cash and cash equivalents of $17.3 million, and $24.0 million of debt outstanding under its debt and capital lease obligations, net of debt discount. As discussed in Note 18, in March 2017, the Company received net proceeds of $24.0 million in connection with the issuance of a debt obligation to JGB Collateral LLC and certain of its affiliates (“JGB”), of which $11.2 million was used to repay the Company’s outstanding debt obligations to East West Bank. In addition, the debt agreement requires the Company to maintain a minimum of $9.4 million of cash at a named financial institution. These funds are restricted as to withdrawal and are not available to the Company to fund its operations or repay indebtedness. Pursuant to the Company’s convertible debt financing agreements, the Company is required to file a registration statement with the SEC registering for resale the shares underlying the securities issued or issuable to JGB in the financing. Because the Company failed to file the registration statement with the SEC by April 17, 2017, commencing on April 18, 2017, the Company began accruing liquidated damages payable to JGB at a rate of approximately $7,000 per day. These damages will continue to accrue at the same rate on a daily basis until the registration statement is filed with the SEC. Due to insufficient working capital in Allenex, a debt covenant in the Company’s Term Loan Facility Agreement (the “Term Loan Facility”) with Danske Bank A/S (“Danske”) relating to maintaining an adequate leverage ratio was violated at each of June 30, 2016, September 30, 2016 and December 31, 2016. The Company obtained waivers from Danske for the violations of the debt covenant as of June 30, 2016 and September 30, 2016. For the violation as of December 31, 2016, the Company received a conditional waiver from Danske based on the preliminary consolidated financial statements for Allenex as of and for the three months and year ended December 31, 2016 prepared under International Financial Reporting Standards as adopted in Sweden and for regulatory reporting in Sweden. Any change to the preliminary Allenex consolidated financial statements could result in a withdrawal of the conditional waiver and could result in Danske demanding repayment of the debt outstanding. While Allenex received waivers from Danske for the violations, due to continuing liquidity matters, the Company has determined that it is not probable that Allenex will be in compliance with this covenant in future periods. For these reasons, the long-term debt due to Danske is classified as a current liability in the consolidated balance sheet as of December 31, 2016. Absent Danske not demanding repayment of the outstanding debt, the Company believes that its cash and cash equivalents of $17.3 million at December 31, 2016, expected revenues and the available net proceeds available to the Company from the debt agreement with JGB will be sufficient to allow the Company to fund its current operations into the quarter ended June 30, 2017. The Company will require additional financing and/or refinancing of its current debt obligations to fund working capital, repay debt and pay its obligations. The Company may pursue financing and refinancing opportunities in both the private and public debt and equity markets through sales of debt or equity securities. Additional financing might include one or more offerings and one or more of a combination of discounted or at-the-market common stock, securities convertible into or exchangeable for shares of common stock, warrants or other rights to purchase or acquire common stock. However, there can be no assurance that the Company will be successful in acquiring additional funding at levels sufficient to fund its operations or on terms favorable to the Company. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a period of one year from the date of the issuance of these financial statements. Moreover, the Company does not believe that it will have sufficient cash to meet its projected operating requirements for the next 12 months from the consolidated balance sheet date included in the Annual Report on Form 10-K unless it raises additional financing. If the Company is unsuccessful in its efforts to raise additional financing and/or refinance the Company’s indebtedness in the near term, the Company will be required to significantly reduce or cease operations. Additionally, due to the substantial doubt about the Company’s ability to continue operating as a going concern and the material adverse change clause in the loan agreement with East West Bank, the entire amount of borrowings at December 31, 2016 has been classified as current in these financial statements. East West Bank has not invoked the material adverse change clause. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern through December 31, 2016, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The financial statements do not reflect any adjustments relating to the recoverability and reclassifications of assets and liabilities that might be necessary if the Company is unable to continue as a going concern.
Reverse Stock Split, and Increase in Authorized Shares	Reverse Stock Split, and Increase in Authorized Shares On July 1, 2014, the Company’s Board of Directors approved an amendment to the Company’s Certificate of Incorporation to reflect a 1 for 6.85 reverse stock split (the “Reverse Stock Split”) of the Company’s outstanding common stock and convertible preferred stock and increase the authorized common stock to 10,000,000 shares, after giving effect to the Reverse Stock Split. The Reverse Stock Split became effective July 14, 2014. The par value per share was not adjusted as a result of the Reverse Stock Split. Effective July 22, 2014, the Company’s certificate of incorporation was amended and restated to provide for 100,000,000 authorized shares of common stock with a par value of $0.001 per share, and 10,000,000 authorized shares of preferred stock with a par value of $0.001 per share. All authorized, issued and outstanding shares of common stock, convertible preferred stock, options and warrants to purchase common or preferred stock and related per share amounts contained in the financial statements have been retroactively adjusted to reflect the Reverse Stock Split for all periods presented.
Initial Public Offering	Initial Public Offering On July 22, 2014, the Company closed its initial public offering (“IPO”) of 4,000,000 shares of its common stock, and issued an additional 220,000 shares of common stock on August 13, 2014 pursuant to the exercise of the over-allotment option granted to its underwriters. The public offering price of the shares sold in the IPO was $10.00 per share. The total proceeds from the IPO to the Company, net of underwriting discounts and commissions of $3.0 million, were $39.2 million. After deducting offering expenses payable by the Company of $3.7 million, net proceeds to the Company were $35.5 million. Upon the closing of the IPO, all shares of convertible preferred stock then outstanding converted into 6,048,220 shares of common stock, and a subordinated convertible note previously issued by the Company in the principal amount of $5.0 million converted into 510,777 shares of common stock. In addition, all of the Company’s convertible preferred stock warrants were converted into warrants to purchase common stock.
Basis of Presentation	Basis of Presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany transactions have been eliminated. Since the Company owns less than 100% of the shares of Allenex, the Company records net loss attributable to noncontrolling interest in its condensed consolidated statements of operations equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. Subsequent to its acquisition in 2014, the financial statements of IMX, which was the Company’s wholly-owned subsidiary and was merged into the Company, were included in the financial statements of the Company.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with 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 and the reported amounts of revenues and expenses in the consolidated financial statements and accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to (i) revenue recognition, (ii) the differences between amounts billed and estimated receipts from payers, (iii) the determination of the accruals for clinical studies, (iv) the determination of refunds to be requested by third-party payers, (v) the fair value of assets and liabilities, including from acquisitions, (vi) inventory valuation, (vii) the valuation of warrants, Series A Preferred, and common stock issued in the Private Placement and Subsequent Financing, (viii) the fair value of contingent consideration in a business acquisition, (ix) the fair value of embedded derivatives, (x) measurement of stock-based compensation expense, (xi) the determination of the valuation allowance and estimated tax benefit associated with deferred tax assets and net deferred tax liability, (xii) any impairment of long-lived assets, including in-process technology and goodwill, and (xiii) legal contingencies. Actual results could differ from those estimates.
Concentrations of Credit Risk and Other Risks and Uncertainties	Concentrations of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents and accounts receivable. The Company’s policy is to invest its cash and cash equivalents in money market funds, obligations of U.S. government agencies and government-sponsored entities, commercial paper and various bank deposit accounts. These financial instruments were held in Company accounts at eight financial institutions. The counterparties to the agreements relating to the Company’s investments consist of financial institutions of high credit standing. The Company is exposed to credit risk in the event of default by the financial institutions to the extent of amounts recorded on the balance sheets which may be in excess of insured limits. The Company is also subject to credit risk from its accounts receivable, which are derived from revenue earned from AlloMap tests provided for patients located in the U.S. and billed to various third-party payers, and sales of Olerup SSP products to distributors, strategic partners and end customers in Europe, Middle East and Africa, the U.S., Latin America and other geographic regions. The Company has not experienced any significant credit losses and does not generally require collateral on receivables. For the years ended December 31, 2016, 2015 and 2014, approximately 44%, 50% and 51%, respectively, of testing revenue was paid for by Medicare. No other payers represented more than 10% of testing revenue for these periods. Product revenue accounted for 26% of total revenue for the year ended December 31, 2016. No payer accounted for more than 10% of product revenue for this period. At December 31, 2016 and 2015, approximately 27% and 35%, respectively, of accounts receivable was due from Medicare. At December 31, 2016 and 2015, approximately 6 % and 21% of accounts receivable was due from Aetna, respectively. No other payer represented more than 10% of accounts receivable at December 31, 2016 or 2015.
Cash Equivalents	Cash Equivalents Cash equivalents consist of short-term, highly liquid investments with original maturities of three months or less from the date of purchase. Cash equivalents consist primarily of amounts invested in money market funds.
Restricted Cash	Restricted Cash Under lease agreements for certain facilities and an agreement with the State of Florida Medicaid, the Company must maintain letters of credit, minimum collateral requirements and a surety bond. These agreements are collateralized by cash. The cash used to support these arrangements is classified as long-term restricted cash on the accompanying balance sheets.
Inventory	Inventory Inventory is finished goods and raw materials, which consist of AlloMap reagent plates, laboratory supplies, reagents and Olerup SSP kits. Inventories are used in connection with tests performed and may also be used for research and product development efforts. Laboratory supplies subsequently designated for research and product development use are expensed. Obsolete or damaged inventories are written off and excluded from the physical inventory. Inventories are stated at the lower of actual purchased cost, determined on an average cost basis, or net realizable value at our Stockholm, Sweden, location and at the lower of actual purchased cost, determined on a first-in, first-out basis, or net realizable value at our other locations.
Property and Equipment, net	Property and Equipment, net Property and equipment are stated at cost, less accumulated depreciation. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, generally three years for laboratory, computer and office equipment, and generally seven years for furniture and fixtures. Leasehold improvements are amortized over the shorter of their estimated useful lives or the remaining lease term. Assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair market value of the leased asset at the inception of the lease. Amortization expense is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease. The Company capitalizes certain costs incurred for software developed or obtained for internal use. These costs include software licenses, consulting services, and direct materials, as well as employee payroll and payroll-related costs. Capitalized internal-use software costs are depreciated over three years.
Purchased Intangible Assets	Purchased Intangible Assets Amortizable intangible assets include customer relationships, developed technology, trademarks, contracts and in-process research and development (“IPR&D”) identified intangible assets acquired as part of a business combination. Intangible assets subject to amortization are amortized over their estimated useful lives. Acquired intangible assets with indefinite useful lives are related to IPR&D projects and are measured at their respective fair values as of the acquisition date. The Company does not amortize intangible assets with indefinite useful lives. Intangible assets related to IPR&D projects are considered to be indefinite-lived until the completion or abandonment of the associated research and development efforts. If and when development is complete, which generally occurs if and when regulatory approval to market a product is obtained, the associated assets would be deemed finite-lived and would then be amortized based on their respective estimated useful lives at that point in time. The Company tests IPR&D for impairment on an annual basis and in between annual tests if it becomes aware of events or changes that would indicate that it is more likely than not that the fair value of the assets is below their carrying amounts. The IPR&D annual impairment test is performed as of December 1 of each fiscal year. If the fair value exceeds the carrying value, then there is no impairment. Impairment losses on indefinite-lived intangible assets are recognized based solely on a comparison of the fair value of an asset to its carrying value, without consideration of any recoverability test. The Company has not identified any such impairment losses to date.
Impairment of Long-lived Assets	Impairment of Long-lived Assets The Company evaluates its long-lived assets for indicators of possible impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The Company then compares the carrying amounts of the assets with the future net undiscounted cash flows expected to be generated by such asset. Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s fair value determined using discounted estimates of future cash flows. The Company has not identified any such impairment losses to date.
Goodwill	Goodwill Goodwill represents the excess of the cost of an acquisition over the sum of the amounts assigned to tangible and identifiable intangible assets acquired, less liabilities assumed. Goodwill is not subject to amortization, but is tested for impairment on an annual basis and whenever events or changes in circumstances indicate the carrying amount of these assets may not be recoverable. The Company has determined that it operates in two reportable segments associated with the delivery of diagnostic tests and the development and commercialization of diagnostic products. The reporting unit’s carrying value is compared to its fair value. The estimated fair values of the reporting units are determined using either the market approach, income approach or a combination of the market and income approach. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its estimated fair value. The income approach uses expected future operating results and failure to achieve these expected results may cause a future impairment of goodwill at the reporting unit. If the carrying value of the reporting unit exceeds its estimated fair value, the second step of the goodwill impairment test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. The implied fair value is calculated by allocating all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied estimated fair value. The Company conducted its annual goodwill impairment test as of December 1, 2016 and identified an impairment of $13.0 million related to the goodwill recorded in connection with the acquisition of Allenex. See Note 6 for additional discussion regarding the impairment charge recorded.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which the Company would transact, and it takes into consideration the assumptions that market participants would use when pricing the asset or liability. The Company’s assessment of the significance of a particular input to the fair value measurement of an asset or liability requires management to make judgments and to consider specific characteristics of that asset or liability. The carrying amounts of certain of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their short maturities. The carrying amounts of the convertible preferred stock warrant liability and contingent consideration liability also represents their fair values.
Warrants	Warrants On April 14, 2016 and June 15, 2016, the Company completed the Private Placement and Subsequent Financing, respectively (as described in Note 11), which included the issuance of freestanding warrants to certain accredited investors and placement agents to purchase shares of the Company’s common stock. The exercisability of the warrants was contingent upon the receipt of the Requisite Stockholder Approval, which occurred on June 16, 2016. The freestanding warrants issued pursuant to the Private Placement and Subsequent Financing are contingently redeemable and are classified as liabilities on the consolidated balance sheet and recorded at their estimated fair value. The warrants are remeasured at each balance sheet date with changes recorded in change in estimated fair value of common stock warrant and derivative liabilities on the consolidated statements of operations. In 2015, the Company issued warrants to purchase shares of its common stock in connection with a debt financing (see Note 10). The Company accounted for these warrants as equity based on the estimated fair value of the warrants on the issuance date. The fair value of the outstanding warrants was estimated using the Black-Scholes Model. The Black-Scholes Model requires inputs such as the expected term of the warrants, expected volatility and risk-free interest rate. Certain of these inputs are subjective and require significant analysis and judgment to develop. For the estimate of the expected term, the Company used the full remaining contractual term of the warrant. The Company had freestanding warrants enabling counterparties to purchase shares of its convertible preferred stock as of December 31, 2013, which were converted to warrants to purchase common stock on the Company’s IPO date. Upon the completion of the IPO in July 2014, preferred stock warrants were converted into warrants to purchase common stock, and, accordingly, the liability was reclassified to equity and became no longer subject to remeasurement.
Testing Revenue	Testing Revenue The Company recognizes revenues for tests delivered when the following criteria are met: (i) persuasive evidence that an arrangement exists; (ii) delivery has occurred or services rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured. For testing revenue, the first criterion is satisfied when a third-party payer makes a coverage decision or enters into a contractual arrangement with the Company for the test. The second criterion is satisfied when the Company performs the test and delivers the test result to the ordering physician. The third criterion is satisfied if the third-party payer’s coverage decision or reimbursement contract specifies a price for the test. The fourth criterion is satisfied based on management’s judgments regarding the collectability of the fees charged under the arrangement. Such judgments include review of past payment history. AlloMap testing may be considered investigational by some payers and not covered under their reimbursement policies. Others may cover the test, but not pay a set or determinable amount. As a result, in the absence of a reimbursement agreement or sufficient payment history, collectability cannot reasonably be assured so revenue is not recognized at the time the test is delivered. If all criteria set forth above are met, revenue is recognized. When the first, third or fourth criteria are not met but third-party payers make a payment to the Company for tests performed, the Company recognizes revenue on the cash basis in the period in which the payment is received. Revenue for tests performed is recognized on the accrual basis net of adjustments for differences between amounts billed and the estimated receipts from payers. The amount the Company expects to collect may be lower than the agreed upon amount due to several factors, such as the amount of patient co-payments, the existence of secondary payers and claim denials. Estimated receipts are based upon historical payment practices of payers. Differences between estimated and actual cash receipts are recorded as an adjustment to revenue, which have been immaterial to date. Taxes assessed by governmental authorities on revenue, including sales and value added taxes, are excluded from revenue in the statements of operations.
Product Revenue	Product Revenue Product revenue is recognized from the sale of products to end-users, distributors and strategic partners when persuasive evidence of an arrangement exists, the product is complete and tested and has been shipped or delivered, as required to transfer title and risk of loss, the sales price is fixed and determinable, collection of the resulting receivable is reasonably assured, there are no material contingencies and the Company does not have significant obligations for future performance. When collectability is not reasonably assured, the Company defers the revenue until the cash is received. Provisions for estimated future product returns and allowances are recorded in the period of the sale based on the historical and anticipated future rate of returns. Revenue is recorded net of any discounts given to the buyer.
Collaboration and License Revenue	Collaboration and License Revenue The Company generates revenue from collaboration and license agreements. Collaboration and license agreements may include non-refundable upfront payments, partial or complete reimbursement of research and development costs, contingent payments based on the occurrence of specified events under the agreements, license fees and royalties on sales of products or product candidates if they are successfully commercialized. The Company’s performance obligations under the collaborations may include the transfer of intellectual property rights in the form of licenses, obligations to provide research and development services and obligations to participate on certain development committees with the collaboration partners. The Company makes judgments that affect the periods over which it recognizes revenue. The Company periodically reviews its estimated periods of performance based on the progress under each arrangement and accounts for the impact of any change in estimated periods of performance on a prospective basis. The Company recognizes contingent consideration received from the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved, which the Company believes is consistent with the substance of its performance under its various license and collaboration agreements. The Company did not recognize any revenue connected with milestones during the years ended December 31, 2016, 2015 or 2014.
Cost of Testing and Product	Cost of Testing Cost of testing reflects the aggregate costs incurred in delivering the Company’s AlloMap test results to clinicians. The components of cost of testing are materials and service costs, direct labor costs, stock-based compensation, equipment and infrastructure expenses associated with testing samples, shipping, logistics and specimen processing charges to collect and transport samples and allocated overhead including rent, information technology, equipment depreciation, utilities and royalties. Costs associated with performing tests (except royalties) are recorded as the test is processed regardless of whether and when the testing revenue is recognized with respect to that test. As a result, the Company’s cost of testing as a percentage of revenue may vary significantly from period to period because the Company does not recognize all revenue in the period in which the associated costs are incurred. Royalties for licensed technology, calculated as a percentage of test revenues, are recorded as license fees in cost of testing at the time the test revenues are recognized. Cost of Product Cost of product reflects the aggregate costs incurred in delivering the Company’s products to customers. The components of cost of product are materials costs, manufacturing and kit assembly costs, direct labor costs, equipment and infrastructure expenses associated with preparing kitted products for shipment, shipping, and allocated overhead including rent, information technology, equipment depreciation and utilities. Cost of product also includes amortization of acquired developed technology and adjustments to inventory values, including write-down of impaired, slow moving or obsolete inventory.
Business Combinations	Business Combinations The Company determines and allocates the purchase price of an acquired business to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the business combination date, including identifiable intangible assets which either arise from a contractual or legal right or are separable from goodwill. The Company bases the estimated fair value of identifiable intangible assets acquired in a business combination on independent valuations that use information and assumptions provided by management, which consider management’s best estimates of inputs and assumptions that a market participant would use. The Company allocates any excess purchase price over the estimated fair value assigned to the net tangible and identifiable intangible assets acquired and liabilities assumed to goodwill. The use of alternative valuation assumptions, including estimated revenue projections, growth rates, royalty rates, cash flows, discount rates, estimated useful lives and probabilities surrounding the achievement of contingent milestones could result in different purchase price allocations and amortization expense in current and future periods. In those circumstances where an acquisition involves a contingent consideration arrangement that meets the definition of a liability under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 480, Distinguishing Liabilities from Equity, the Company recognizes a liability equal to the fair value of the contingent payments the Company expects to make as of the acquisition date. The Company remeasures this liability each reporting period and records changes in the fair value as a component of operating expenses. Transaction costs associated with acquisitions are expensed as incurred in general and administrative expenses. Results of operations and cash flows of acquired companies are included in the Company’s operating results from the date of acquisition.
Research and Development Expenses	Research and Development Expenses Research and development expenses represent costs incurred to develop new surveillance solutions as well as continued development of the Company’s AlloMap test. These expenses include payroll and related expenses, consulting expenses, laboratory supplies, and certain allocated expenses as well as amounts incurred under certain collaboration and license agreements. Research and development costs are expensed as incurred. The Company records accruals for estimated study costs comprised of work performed by contract research organizations under contract terms.
Advertising Expenses	Advertising Expenses All advertising costs are expensed as incurred. Advertising expenses were insignificant during all of the periods presented.
Stock-based Compensation	Stock-based Compensation The Company uses the Black-Scholes Model, which requires the use of estimates such as stock price volatility and expected option lives, to value employee stock options. The Company estimates the expected option lives using historical data, volatility using its own historical stock prices and stock prices of peer companies in the diagnostics industry, risk-free rates using the implied yield currently available in the U.S. Treasury zero-coupon issues with a remaining term equal to the expected option lives, and dividend yield using the Company’s expectations and historical data. The fair value of each restricted stock unit is calculated based upon the closing price of the Company’s common stock on the date of the grant. The Company uses the straight-line attribution method for recognizing compensation expense. Compensation expense is recognized on awards ultimately expected to vest and reduced for forfeitures that are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures are estimated based on the Company’s historical experience. Compensation expense for stock options issued to nonemployees is calculated using the Black-Scholes Model and is recorded over the service performance period. Options subject to vesting are required to be periodically remeasured over their service performance period, which is generally the same as the vesting period.
Income Taxes	Income Taxes The Company accounts for income taxes under the liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company assesses all material positions taken in any income tax return, including all significant uncertain positions, in all tax years that are still subject to assessment or challenge by relevant taxing authorities. The Company’s assessment of an uncertain tax position begins with the initial determination of the position’s sustainability and is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. As of each balance sheet date, unresolved uncertain tax positions must be reassessed, and the Company will determine whether (i) the factors underlying the sustainability assertion have changed and (ii) the amount of the recognized tax benefit is still appropriate. The recognition and measurement of tax benefits requires significant judgment. Judgments concerning the recognition and measurement of a tax benefit may change as new information becomes available.
Foreign Currency Translation	Foreign Currency Translation The functional currency of the Company’s foreign subsidiaries is the local currency for each entity, including the Swedish Krona and the Euro. The revenue and expenses of such subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities have been translated at the rates of exchange on the balance sheet date. The resulting cumulative translation adjustments are reported in other comprehensive loss. Foreign currency transaction gains and losses are recognized in current operations.
Comprehensive (Loss) Income	Comprehensive (Loss) Income Comprehensive (loss) income consists of net (loss) income and other gains and losses affecting stockholders’ equity that, under U.S. GAAP, are excluded from net income or loss. For the Company, such items consist of foreign currency translation losses.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2015, the FASB issued ASU No. 2015-05, Intangibles—Goodwill and Other—Internal Use Software (Subtopic 350-40). This updated standard provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. An entity can elect to adopt the amendments either (i) prospectively to all arrangements entered into or materially modified after the effective date or (ii) retrospectively. For prospective transition, the only disclosure requirements at transition are the nature of and reason for the change in accounting principle, the transition method, and a qualitative description of the financial statement line items affected by the change. For retrospective transition, the disclosure requirements at transition include the requirements for prospective transition and quantitative information about the effects of the accounting change. The Company adopted this guidance as of January 1, 2016 as required using the prospective method. There have been no new or existing arrangements that were materially modified following the date of adoption. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. The guidance is effective for the Company beginning on January 1, 2017 with early adoption permitted as of the beginning of any interim or annual reporting period, and it may be applied either (i) prospectively to all deferred tax assets and liabilities, or (ii) retrospectively to all periods presented. If an entity applies the guidance prospectively, the entity should disclose in the first interim and first annual period of change, the nature of and reason for the change in accounting principle and a statement that prior periods were not retrospectively adjusted. If an entity applies the guidance retrospectively, the entity is required to disclose in the first interim and first annual period of change, the nature of and reason for the change in accounting principle and quantitative information about the effects of the accounting change on prior periods. The Company adopted this guidance early as of January 1, 2016 prospectively, which required its deferred tax assets and liabilities to be reclassified from other current assets and liabilities to their respective noncurrent categories on its condensed balance sheets. As of December 31, 2016, the Company had a net noncurrent deferred tax liability of approximately $6.1 million attributable to the acquisition of Allenex. The adoption of this guidance did not result in any material impact on the Company’s condensed financial statements. In February 2016, the Financial Accounting Standards Board (the “FASB”), issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), which, for operating leases, requires the lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The guidance also requires a lessee to recognize single lease costs, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. This guidance will be effective for the Company in fiscal year 2019 and must be adopted using a modified retrospective transition approach. Early adoption is permitted. The Company is currently assessing the impact of this guidance will have on its consolidated financial statements In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging: Contingent Put and Call Options in Debt Instruments, to clarify when a contingent put or call option to accelerate the repayment of debt is an embedded derivative. The guidance is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. The adoption of this guidance is on a modified retrospective basis. The Company is currently assessing the impact of this guidance on its condensed financial statements. In March 2016, the FASB issued ASU No 2016-09, Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting. This ASU simplifies the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. This ASU will be effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the potential effects of this ASU on its consolidated financial statements. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing (“ASU 2016-10”). In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”). These amendments provide additional clarification and implementation guidance on the previously issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), or (“ASU 2014-09”), which is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled to when products are transferred to customers. The amendments in ASU 2016-10 provide clarifying guidance on materiality of performance obligations; evaluating distinct performance obligations; treatment of shipping and handling costs; and determining whether an entity’s promise to grant a license provides a customer with either a right to use an entity’s intellectual property or a right to access an entity’s intellectual property. The amendments in ASU 2016-08 clarify how an entity should identify the specified good or service for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which addresses certain issues on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which makes technical corrections and improvements to the new revenue standard. These ASUs will be effective for the Company in the first quarter of fiscal year 2018. The guidance may be applied (i) retrospectively to each prior period presented, or (ii) retrospectively with the cumulative effect recognized as of the date of adoption. The Company has not formed an implementation work team or commenced a review of its revenue generating contracts or agreements to assess and quantify the impacts the adoption of ASU 2014-09 will have on the Company’s financial position and results of operations. In addition, the Company has not yet selected an adoption method for this standard. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), to reduce the diversity in practice with respect to the presentation of certain cash flows. The ASU is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. Adoption of the ASU is retrospective. The Company is currently assessing the impact of the ASU on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force) (“ASU 2016-18”). This guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for all interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-18 to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). In an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments of ASU 2017-01 are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company does not expect the adoption of ASU 2017-01 to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). This guidance eliminates Step 2 from the goodwill impairment test. Instead, under the amendments in ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. ASU 2017-04 is effective for all interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.
