Summary Of Significant Accounting Policies [Abstract] | |
Summary Of Significant Accounting Policies | NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation In the opinion of management, our accompanying unaudited Condensed Consolidated Financial Statements (“Financial Statements”) have been prepared on a consistent basis with our December 31, 2015 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and, as permitted by such rules and regulations, omit certain information and footnote disclosures necessary to present the statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015. The results of operations for the six -month period ended June 30 , 2016 are not necessarily indicative of the results to be expected for the entire year or any future periods. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes to the financial statements. Our estimates include, but are not limited to, the valuation of inventory, revenue valuation, the valuation of a financing derivative and long-term notes, the valuation and recognition of share-based compensation, the delivery period for collaboration agreements, the useful lives assigned to long-lived assets, and the computation provisions for income taxes. Actual results could differ materially from these estimates . Fair Value of Financial Instruments Assets and liabilities measured at fair value on a recurring basis The following table sets forth the fair value of our financial assets and liabilities measured on a recurring basis as of June 30, 2016 and December 31, 2015, respectively: (in thousands) June 30, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Cash and cash equivalents: Cash and money market funds $ 22,444 $ — $ — $ 22,444 $ 22,034 $ — $ — $ 22,034 Commercial paper — 2,334 — 2,334 — 8,595 — 8,595 US government & agency securities — — — — — 3,000 — 3,000 Total cash and cash equivalents 22,444 2,334 — 24,778 22,034 11,595 — 33,629 Investments: Commercial paper — 29,298 — 29,298 — 15,903 — 15,903 Corporate debt securities — 9,649 — 9,649 — 1,265 — 1,265 US government & agency securities — 35,608 — 35,608 — 28,136 — 28,136 Asset backed securities — 3,137 — 3,137 — 3,337 — 3,337 Total investments — 77,692 — 77,692 — 48,641 — 48,641 Long-term restricted cash: Cash 4,500 — — 4,500 4,500 — — 4,500 Total assets measured at fair value $ 26,944 $ 80,026 $ — $ 106,970 $ 26,534 $ 60,236 $ — $ 86,770 Liabilities Financing derivative $ — $ — $ 264 $ 264 $ — $ — $ 600 $ 600 Total liabilities measured at fair value $ — $ — $ 264 $ 264 $ — $ — $ 600 $ 600 We classify our cash deposits and money market funds within Level 1 of the fair value hierarchy because they are valued using bank balances or quoted market prices. We classify our investments as Level 2 instruments based on market pricing and other observable inputs. We did not classify any of our investments within Level 3 of the fair value hierarchy. During the six- month periods ended June 30, 2016 and 2015, there were no impairments of our investments. The estimated fair value of the Financing Derivative liability (as defined in Note 6. Notes Payable) was determined using Level 3 inputs, or significant unobservable inputs. Refer to Note 6. Notes Payable for a detailed description and valuation approach. Changes to the estimated fair value of the Financing Derivative are recorded in “Other income (expense), net” in the condensed consolidated statements of operations and comprehensive loss. The following table provides the changes in the estimated fair value of the Financi ng Derivative during the six -month period ended June 30 , 2016 (in thousands): Financing Derivative Amount Balance as of December 31, 2015 $ 600 Gain on change in estimated fair value (336) Balance as of June 30, 2016 $ 264 During the six -month period ended June 30 , 2016 there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value on a recurring basis and the valuation techniques used did not change compared to our established practice. Financial assets and liabilities not measured at fair value on a recurring basis The carrying amount of our accounts receivable, prepaid expenses, other current assets, accounts payable, accrued expenses and other liabilities, current, approximate fair value due to their short maturities. The carrying value of our other liabilities, non-current, approximates fair value due to the time to maturity and prevailing market rates. We determined the estimated fair value of the Notes (as defined in Note 6. Notes Payable) using Level 3 inputs, or significant unobservable inputs. The estimated fair value of the Notes was determined by comparing the difference between the estimated fair value of the Notes with and without the Financing Derivative by calculating the respective present values from future cash flows using a weighted average market yield of 11.3% and 13.5% at June 30 , 2016 and December 31, 2015, respectively. The estimated fair value and carrying value of the Notes are as follows (in thousands): June 30, 2016 December 31, 2015 Fair Value Carrying Value Fair Value Carrying Value Notes payable $ 19,349 $ 15,496 $ 18,037 $ 14,948 Net Loss per Share The following outstanding common stock options and warrants to purchase common stock were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect: Six Months Ended June 30, (in thousands) 2016 2015 Options outstanding 22,588 18,768 Warrants to purchase common stock — 5,500 Recent Accounting Pronouncements Recently Adopted Accounting Standards In July 2015, the Financial Accounting Standards Board (“FASB”) FASB issued Accounting Standards Update (“ASU”) No. 2015-11, Simplifying the Measurement of Inventory , which simplifies the subsequent measurement of inventory by replacing today’s lower of cost or market test with a lower of cost and net realizable value test. The guidance applies only to inventories for which cost is determined by methods other than last-in first-out (“LIFO”) and the retail inventory method (“RIM”). Entities that use LIFO or RIM will continue to use existing impairment models (e.g., entities using LIFO would apply the lower of cost or market test). ASU 2015-11 is effective for annual report periods beginning after December 15, 2016 and is effective for us in the first quarter of 2017. Early adoption is permitted as of the beginning of an interim or annual reporting period. The new guidance must be applied prospectively after the date of adoption. We have elected to early adopt ASU 2015-11 effective for the three-month period ended March 31, 2016, as permitted by the standard. The early adoption of this update did not have a material impact on our condensed consolidated financial statements. Recently Issued Accounting Standards In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which amends the current stock compensation guidance. The amendments simplify the accounting for the taxes related to stock based compensation, including adjustments to how excess tax benefits and a company's payments for tax withholdings should be classified. The standard is effective for fiscal periods beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases. The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or the cumulative effect transition method. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date , which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. Accordingly, the updated standard is effective for us in the first quarter of 2018. We are currently evaluating the new guidance to determine the impact it may have to our condensed consolidated financial statements. |

Contractual Revenue [Abstract] | |
Contractual Revenue | NOTE 3. CONTRACTUAL REVENUE During September 2013, we entered into a Development, Commercialization and License Agreement (the “Roche Agreement”) with F. Hoffman-La Roche Ltd (“Roche”), pursuant to which we account for, and recognize as revenue, the up-front payment received thereunder using the proportional performance method over the periods in which the delivery of elements pursuant to the Roche Agreement occurs. We recognize revenue under this agreement using a straight-line convention over the service periods of the deliverables as this method approximates our performance of services pursuant to the agreement. Out of the $35.0 million upfront cash payment received, quarterly amortization of $1.7 million has been recognized as contractual revenue from the fourth quarter of 2013 to the fourth quarter of 2014. Beginning in the three-month period ended March 31, 2015, we revised the estimated development period related to our contractual revenue amortization based on increasing certainty of the development time on a prospective approach and quarterly amortization of $3.6 million has been recognized as contractual revenue for each of the four quarters of 2015 and for the each of the first two quarter s of 2016. As of June 30, 2016 total deferred contractual revenue balance was $4.9 million, out of which $3.6 million related to the amount allocated to intellectual property licenses and research and development services and will be amortized in the third quarter of 2016, and the remaining $1.3 million related to the amount allocated to the deliverable of our participation on the joint steering committee will be fully amortized by the third quarter of 2026. Further, the Roche Agreement provide d for additional payments totaling up to $40.0 million upon the achievement of certain development milestones. Consideration from development milestones is recognized in the period in which a milestone is achieved only if the milestone is considered substantive in its entirety. We achieved the first development milestone under the Roche Agreement and reco gnized the related $10.0 million as contractual revenue during the year ended December 31, 2014. We achieved the second and third (final) development milestones under the Roche Agreement and recognized the related $10.0 million and $20.0 million as contractual revenue during the three-month period ended June 30, 2015 and December 31, 2015, respectively. |

Notes Payable [Abstract] | |
Notes Payable | NOTE 6. NOTES PAYABLE Pursuant to a Facility Agreement (the “Facility Agreement”) we entered into with entities affiliated with Deerfield Management Company, L.P. (collectively, “Deerfield”) during February 2013, we issued promissory notes in the aggregate principal amount of $20.5 million (the “Notes”). The Notes bear simple interest at a rate of 8.75% per annum, payable quarterly in arrears commencing on April 1, 2013. In connection with the execution of the Facility Agreement, we issued warrants to purchase an aggregate of 5,500,000 shares of common stock immediately exercisable at an exercise price per share initially equal to $2.63 (the “Warrants”). As of June 30, 2016 , no warrants remained outstanding. Please see Note 8 Stockholders’ equity and share-based compensation for the warrant-related activities during the six-month period ended June 30, 2016. In addition, the Facility Agreement requires us to maintain consolidated cash and cash equivalents on the last day of each calendar quarter of not less than $2.0 million. As security for our repayment of our obligations under the Facility Agreement, we granted to Deerfield a security interest in substantially all of our property. The Facility Agreement has a maximum term of seven years from inception. Subsequent to the date of the Facility Agreement, at the election of the holders of Notes representing a majority of the aggregate principal amount of the outstanding Notes, the Notes holders may elect to receive 25% of the net proceeds from any financing that includes an equity component, including without limitation, the sale or issuance of our common stock, options, warrants or other securities convertible or exchangeable for shares of our common stock, as payment of the Notes. This right is subject to certain exceptions set forth in the Facility Agreement. The Notes holders have the option to require us to repay the Notes if we complete a Major Transaction (as defined in the Facility Agreement), including a change of control or a sale of all or substantially all of our assets. Additionally, the principal balance of the Facility Agreement may become immediately due and payable upon an Event of Default (as defined in the Facility Agreement), in which case the Notes holders would have the right to require us to repay 100% of the principal amount of the loan, plus any accrued and unpaid interest thereon. The Facility Agreement does not provide for a prepayment of the Notes at our option. Financing Derivative A number of features embedded in the Notes to the Facility Agreement met the requirements to be accounted for as a derivative, including the indemnification of certain withholding taxes and the acceleration of debt upon (i) a qualified financing, (ii) an Event of Default, (iii) a Major Transaction, and (iv) the exercise of the warrant via offset to debt principal. These features represent a single derivative (the “Financing Derivative”) that was bifurcated from the debt instrument and accounted for as a liability at fair value, with changes in fair value between reporting periods recorded in other income (expense), net. The estimated fair value of the Financing Derivative was determined by comparing the difference between the fair value of the Notes with and without the Financing Derivative by calculating the respective present values from future cash flows using 11.3% and 13.5% weighted average market yield at June 30 , 2016 and December 31, 2015, respectively. The estimated fair value of the Financing Derivative as of June 30 , 2016 and December 31, 2015 was $0.3 million and $0.6 million , respectively . Notes We initially recorded the Notes and Warrants at $14.1 million and $6.4 million, respectively, based upon the relative fair value allocation of the $20.5 million of proceeds. The carrying value of the Notes at the inception of the debt was $12.8 million, resulting in an original issue discount of $7.7 million. As of June 30, 2016 and December 31, 2015, a debt discount of $4.9 million and $5.4 million, respectively, remained to be amortized through February 2020 , the maturity of the Notes. |

Leases [Abstract] | |
Leases | NOTE 7. LEASES In December 2009 we entered into a lease agreement for a manufacturing and office facility in Menlo Park. In order for the facility to meet our needs and operating requirements, substantial tenant improvements, including improvements to the structural elements and principal operating systems of the facility, were necessary. The lessor provided a tenant improvement allowance of $1.8 million to apply towards the necessary improvements and we remained obligated for additional amounts over the afforded allowance. Due to our involvement in and the nature of the renovations made to the facility and our obligations to fund the costs of renovations exceeding the incentives afforded to us, we account for the facility as if we are the owner. Accordingly, we recorded $3.0 million of building and leasehold improvement assets, reflecting the $1.2 million fair value of the facility prior to commencing renovations and the $1.8 million of landlord incentives within property and equipment, net and a corresponding liability recorded to facility financing obligation. As a result of the lease amendment agreement described below, future rent expense associated with our existing Menlo Park facility leases was reduced to zero . The remaining long-term facility financing obligations associated with these leases, presented as “Other liabilities, non-current” on the condensed consolidated balance sheets at June 30 , 2016 and December 31, 2015, were $1.5 million and $1.4 million, respectively. Lease Amendment Agreement On July 23, 2015, we entered into a Lease Amendment Agreement (the “Lease Amendment Agreement”) with Peninsula Innovation Partners, LLC (the “Existing Landlord”), which amends the terms and conditions of certain of our existing Menlo Park facility real property leases. The Lease Amendment Agreement provides for, among other things, amendments of the term for certain of the existing leases, the termination of all renewal, expansion and extension rights contained in any of the existing leases with the Existing Landlord (including our options to extend the terms for certain of the existing leases for two consecutive five-year periods), as well as rent abatement for a specified period of time. As consideration for our agreement to amend the existing leases pursuant to the Lease Amendment Agreement, and subject to the terms and conditions contained therein, we became eligible to receive up to four payments of $5.0 million each from the Existing Landlord over time (the “Landlord Payments”), and rent abatement for the remainder of the lease. In the event that we breach any of the leases and fail to cure such breach within the time permitted, the Existing Landlord would have no obligation to make the final $5.0 million payment. On September 1, 2015, the permitting process related to an architectural approval and a change of use permit with respect to our new premises at 1315 O’Brien Drive, Menlo Park, California (the “O’Brien Premises”) was completed, which satisfied the contingencies under the Lease Amendment Agreement. As a result, we recorded $23.0 million in “Gain on lease amendments” in the consolidated statements of operations and comprehensive loss for the three-month period ended September 30, 2015, reflecting that our rent payments were reduced to zero for the remaining term of our existing Menlo Park facility real property leases, the aggregate of $20.0 million in Landlord Payments became receivable and any associated financing obligation was revalued. Of the $20.0 million in Landlord Payments, the first $5.0 million Landlord Payment was received in September 2015 and the second $5.0 million Landlord Payment was received in February 2016. At June 30, 2016, the third $5.0 million Landlord Payment was recorded as a short term receivable in “Prepaid Expenses and Other Current Assets” . On June 10, 2016 we entered into a Second Lease Amendment Agreement with the Existing Landlord that modified the payment schedule for the final $5.0 million, such that $2.6 million became a short term receivable and was recorded in “Prepaid Expenses and Other Current Assets” and $ 2.4 million was recorded in “Other Long-term Assets” in the condensed consolidated balance sheets . We do not believe that there are any remaining performance obligations relating to the remaining Landlord Payments. O’Brien Lease Agreement On July 22, 2015, we entered into a new lease agreement (the “O’Brien Lease”) with respect to the O’Brien Premises. The term of the O’Brien Lease is one hundred thirty-two (132) months, commencing on the date that is the later of April 15, 2016 or the date on which the O’Brien Premises landlord has substantially completed certain shell improvements and tenant improvements. Based on the currently agreed construction schedule, the O’Brien Lease is expected to comme n ce in the third quarter of 2016 . Base monthly rent will be abated for the first six (6) months of the lease term and thereafter will be $540,000 per month during the first year of the lease term, with specified annual increases thereafter until reaching $711,000 per month during the last twelve (12) months of the lease term. We were required to pay $2,160,000 in prepaid rent which will be applied to the monthly rent installments due for the first to fourth months after the rent abatement period. We were required to establish a deposit of $4.5 million in the form of a letter of credit in October 2015; and, as such, $4.5 million was recorded in “Long-term restricted cash” in the condensed consolidated balance sheet as of both June 30 , 2016 and December 31, 2015. The landlord is obligated to construct certain shell improvements at the landlord’s cost and expense and provide us with improvement allowances in the amount of $12.6 million. Under the O’Brien Lease, we expect to pay approximately $80 million in rent and $24 million in operating expenses over the expected lease term. In addition to the lease payments, we are also required to reimburse the landlord for certain improvement costs in excess of the tenant improvement allowances provided. These improvement costs, along with the costs associated with the anticipated move to the O’Brien Premises, are expected to be substantial in nature. These future expenditures are expected to be partially offset by the $10.0 million of future Landlord Payments from our Existing Landlord as described above. |

Stockholders' Equity And Share-Based Compensation | NOTE 8. STOCKHOLDERS’ EQUITY AND SHARE-BASED COMPENSATION Equity Offering During the three-month period ended March 31, 2016, we issued 3.1 million shares of our common stock at an average price of $8.80 per share through our “at-the-market” offering, resulting in net proceeds of $26.5 million. During the three -month period ended June 30 , 2016, we issued 3.4 million shares of our common stock at an average price of $9.56 per share through our “at-the-market” offering , resulting in net proceeds of $31.7 million. In total, for the six-month period ended June 30, 2016, we issued 6.5 million shares of our common stock through our “at-the-market” offering, resulting in net proceeds of $58.2 million. As of June 30 , 2016, no shares of common stock remained available for future sales through our “at-the-market” offering. Warrants In connection with the execution of the Facility Agreement, we issued immediately exercisable warrants to purchase 5,500,000 shares of common stock at an exercise price per share initially equal to $2.63 , all of which were outstanding at December 31, 2015. The number of shares of common stock into which the warrants are exercisable and the exercise price will be adjusted to reflect any stock splits, payment of stock dividends, recapitalizations, reclassifications or other similar adjustments in the number of outstanding shares of common stock. The exercise price may also be adjusted to reflect certain dividends or other distributions, including distributions of stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement or similar transaction . During the three months ended March 31, 2016, warrants to purchase 3,818,000 shares of common stock were net exercised, resulting in the issuance of approximately 3.0 million shares. During the three months ended June 30, 2016, warrants to purchase the remaining 1,682,000 shares of common stock were net exercised, resulting in the issuance of approximately 1.2 million shares in the first week of July 2016. The cashless net exercises of the warrants did not result in any additional funds being collected by us. As of June 30, 2016, no warrants remained outstanding. Equity Plans As of June 30 , 2016, we had three active equity compensation plans: the 2010 Equity Incentive Plan, the 2010 Outside Director Equity Incentive Plan, and the 2010 Employee Stock Purchase Plan (“ESPP”). The following table summarizes stock option activity for all our stock option plans for the six -month period ended June 30 , 2016 (in thousands, except per share amounts): Stock Options Outstanding Weighted Shares available Number average for grant of options Exercise price exercise price Balances, December 31, 2015 5,814 19,468 $ 0.70 – 16.00 $ 5.69 Additional shares reserved 4,799 — Options granted (3,867) 3,867 7.87 – 12.85 8.74 Options exercised — (519) 0.70 – 8.90 3.48 Options canceled 228 (228) 1.16 – 15.98 6.80 Balances, June 30, 2016 6,974 22,588 $ 1.16 – 16.00 $ 6.25 Shares issued under our ESPP totaled 668,566 and 532,217 shares during the six -month periods ended June 30 , 2016 and 2015, respectively. As of June 30 , 2016, 1,328,736 shares of our common stock remain available for issuance under our ESPP.

Summary Of Significant Accounting Policies [Abstract] | |
Basis Of Presentation | Basis of Presentation In the opinion of management, our accompanying unaudited Condensed Consolidated Financial Statements (“Financial Statements”) have been prepared on a consistent basis with our December 31, 2015 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and, as permitted by such rules and regulations, omit certain information and footnote disclosures necessary to present the statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015. The results of operations for the six -month period ended June 30 , 2016 are not necessarily indicative of the results to be expected for the entire year or any future periods. |
Use Of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes to the financial statements. Our estimates include, but are not limited to, the valuation of inventory, revenue valuation, the valuation of a financing derivative and long-term notes, the valuation and recognition of share-based compensation, the delivery period for collaboration agreements, the useful lives assigned to long-lived assets, and the computation provisions for income taxes. Actual results could differ materially from these estimates . |
Fair Value Of Financial Instruments | Fair Value of Financial Instruments Assets and liabilities measured at fair value on a recurring basis The following table sets forth the fair value of our financial assets and liabilities measured on a recurring basis as of June 30, 2016 and December 31, 2015, respectively: (in thousands) June 30, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Cash and cash equivalents: Cash and money market funds $ 22,444 $ — $ — $ 22,444 $ 22,034 $ — $ — $ 22,034 Commercial paper — 2,334 — 2,334 — 8,595 — 8,595 US government & agency securities — — — — — 3,000 — 3,000 Total cash and cash equivalents 22,444 2,334 — 24,778 22,034 11,595 — 33,629 Investments: Commercial paper — 29,298 — 29,298 — 15,903 — 15,903 Corporate debt securities — 9,649 — 9,649 — 1,265 — 1,265 US government & agency securities — 35,608 — 35,608 — 28,136 — 28,136 Asset backed securities — 3,137 — 3,137 — 3,337 — 3,337 Total investments — 77,692 — 77,692 — 48,641 — 48,641 Long-term restricted cash: Cash 4,500 — — 4,500 4,500 — — 4,500 Total assets measured at fair value $ 26,944 $ 80,026 $ — $ 106,970 $ 26,534 $ 60,236 $ — $ 86,770 Liabilities Financing derivative $ — $ — $ 264 $ 264 $ — $ — $ 600 $ 600 Total liabilities measured at fair value $ — $ — $ 264 $ 264 $ — $ — $ 600 $ 600 We classify our cash deposits and money market funds within Level 1 of the fair value hierarchy because they are valued using bank balances or quoted market prices. We classify our investments as Level 2 instruments based on market pricing and other observable inputs. We did not classify any of our investments within Level 3 of the fair value hierarchy. During the six- month periods ended June 30, 2016 and 2015, there were no impairments of our investments. The estimated fair value of the Financing Derivative liability (as defined in Note 6. Notes Payable) was determined using Level 3 inputs, or significant unobservable inputs. Refer to Note 6. Notes Payable for a detailed description and valuation approach. Changes to the estimated fair value of the Financing Derivative are recorded in “Other income (expense), net” in the condensed consolidated statements of operations and comprehensive loss. The following table provides the changes in the estimated fair value of the Financi ng Derivative during the six -month period ended June 30 , 2016 (in thousands): Financing Derivative Amount Balance as of December 31, 2015 $ 600 Gain on change in estimated fair value (336) Balance as of June 30, 2016 $ 264 During the six -month period ended June 30 , 2016 there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value on a recurring basis and the valuation techniques used did not change compared to our established practice. Financial assets and liabilities not measured at fair value on a recurring basis The carrying amount of our accounts receivable, prepaid expenses, other current assets, accounts payable, accrued expenses and other liabilities, current, approximate fair value due to their short maturities. The carrying value of our other liabilities, non-current, approximates fair value due to the time to maturity and prevailing market rates. We determined the estimated fair value of the Notes (as defined in Note 6. Notes Payable) using Level 3 inputs, or significant unobservable inputs. The estimated fair value of the Notes was determined by comparing the difference between the estimated fair value of the Notes with and without the Financing Derivative by calculating the respective present values from future cash flows using a weighted average market yield of 11.3% and 13.5% at June 30 , 2016 and December 31, 2015, respectively. The estimated fair value and carrying value of the Notes are as follows (in thousands): June 30, 2016 December 31, 2015 Fair Value Carrying Value Fair Value Carrying Value Notes payable $ 19,349 $ 15,496 $ 18,037 $ 14,948 |

Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Standards In July 2015, the Financial Accounting Standards Board (“FASB”) FASB issued Accounting Standards Update (“ASU”) No. 2015-11, Simplifying the Measurement of Inventory , which simplifies the subsequent measurement of inventory by replacing today’s lower of cost or market test with a lower of cost and net realizable value test. The guidance applies only to inventories for which cost is determined by methods other than last-in first-out (“LIFO”) and the retail inventory method (“RIM”). Entities that use LIFO or RIM will continue to use existing impairment models (e.g., entities using LIFO would apply the lower of cost or market test). ASU 2015-11 is effective for annual report periods beginning after December 15, 2016 and is effective for us in the first quarter of 2017. Early adoption is permitted as of the beginning of an interim or annual reporting period. The new guidance must be applied prospectively after the date of adoption. We have elected to early adopt ASU 2015-11 effective for the three-month period ended March 31, 2016, as permitted by the standard. The early adoption of this update did not have a material impact on our condensed consolidated financial statements. Recently Issued Accounting Standards In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which amends the current stock compensation guidance. The amendments simplify the accounting for the taxes related to stock based compensation, including adjustments to how excess tax benefits and a company's payments for tax withholdings should be classified. The standard is effective for fiscal periods beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases. The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or the cumulative effect transition method. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date , which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. Accordingly, the updated standard is effective for us in the first quarter of 2018. We are currently evaluating the new guidance to determine the impact it may have to our condensed consolidated financial statements. |
