Overview and Basis of Presentat

Overview and Basis of Presentation	6 Months Ended

Accounting Policies [Abstract]
Overview and Basis of Presentation	Ooma, Inc. and its wholly-owned subsidiaries (collectively, “Ooma” or the “Company”) create new communications experiences for businesses and consumers, delivered from its smart cloud-based SaaS platform. The Company was founded in 2003 and is headquartered in Sunnyvale, California. The Company’s fiscal year ends on January 31. References to fiscal 2020 and fiscal 2019 refer to the fiscal year ending January 31, 2020 and the fiscal year ended January 31, 2019, respectively. In May 2019, the Company acquired Broadsmart Global, Inc. (“Broadsmart”), a provider of cloud-based unified-communications-as-a-service (“UCaaS”) solutions based in Florida. Note 12: Business Acquisition . Principles of Presentation and Consolidation These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2019 (“Annual Report”). These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect The condensed consolidated financial statements include accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the Company’s condensed consolidated financial statements and notes thereto. Significant estimates include, but are not limited to, those related to revenue recognition, inventory valuation, valuation of goodwill and intangible assets, deferred sales commissions, operating lease assets and liabilities, regulatory fees and indirect tax accruals, loss contingencies, stock-based compensation, income taxes (including valuation allowances) and fair value measurements. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. These estimates are based on information available as of the date of the condensed consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates. Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the condensed consolidated statements of operations and differences were not material. Therefore, the condensed consolidated statements of comprehensive loss have been omitted. Recently Adopted Accounting Standards Leases . On February 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) which superseded the guidance in Topic 840 and required the Company to recognize operating leased assets and corresponding liabilities on the balance sheet and to provide enhanced disclosures. The Company adopted Topic 842 using the modified retrospective transition method by applying the new standard to all leases existing at the date of initial adoption and not restating comparative periods. The Company elected the package of practical expedients, which among other things, allowed it to carry forward its historical lease classification and its assessment of whether any existing leases as of the date of adoption are or contain leases. Adoption on February 1, 2019 resulted in the recognition of $4.1 million of operating right-of-use “ROU” assets and $4.3 million of operating lease liabilities on the condensed consolidated balance sheet, with no adjustment to accumulated deficit. The difference of $0.2 million represented deferred rent for leases that existed as of the date of adoption, which was an offset to the opening balance of ROU assets. Adoption of the new standard did not materially impact the Company’s consolidated statements of operations, consolidated statements of stockholders’ equity and consolidated statements of cash flows. The Company has implemented policies, processes and controls to support the standard's measurement and disclosure requirements. See Significant Accounting Policies – Leases Operating Leases Stock-based compensation. The Company adopted ASU 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting in the first quarter of fiscal 2020, which expanded the scope of Topic 718 to include and simplify financial reporting for non-employee stock-based payments. Under the amended standard, most of the guidance on stock compensation for non-employees became aligned with the requirements for employees. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. Significant Accounting Policies – Leases On February 1, 2019, the Company adopted Topic 842 using the modified retrospective transition method by applying the new standard to all leases existing at the date of initial adoption. Comparative prior period amounts have not been adjusted and continue to be reported in accordance with historical accounting under Topic 840. Under Topic 842, the Company determines if an arrangement is a lease at inception. The Company’s leases primarily consist of real property and are classified as operating leases. The Company does not have any finance leases nor material arrangements as a lessor. ROU assets and lease liabilities are recognized at the lease commencement date based upon the present value of the remaining lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease. Lease terms may include options to renew or extend when it is reasonably certain that the option will be exercised. Lease agreements that contain both lease and non-lease components are accounted for as a single component. Short-term leases with an initial term of twelve months or less are not recorded on the balance sheet.

Deferred revenue primarily consists of billings or payments received in advance of meeting revenue recognition criteria. Deferred services revenue is recognized on a ratable basis over the term of the contract as the services are provided. For all arrangements, any revenue that has been deferred and is expected to be recognized beyond one year is classified in long term liabilities on the condensed consolidated balance sheets. Deferred revenue consisted of the following (in thousands): As of July 31, 2019 January 31, 2019 Subscription and services $ 16,205 $ 15,682 Product and other 87 68 Total deferred revenue 16,292 15,750 Less: current deferred revenue 16,044 15,443 Non-current deferred revenue included in other long-term liabilities $ 248 $ 307 During the three and six months ended July 31, 2019, the Company recognized revenue of approximately $3.4 million and $11.8 million, respectively, that was included in the corresponding deferred revenue balance as of January 31, 2019.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 3: Fair Value Measurements The Company records its financial assets and liabilities at fair value. The Company estimates and categorizes fair value by applying the following hierarchy: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Observable prices based on inputs not quoted in active markets, but are corroborated by market data. Level 3: Unobservable inputs that are supported by little or no market activity. The Company’s financial assets that are measured at fair value on a recurring basis by level within the fair value hierarchy were as follows (in thousands): Balance as of July 31, 2019 Balance as of January 31, 2019 Level 1 Level 2 Total Level 1 Level 2 Total Assets: Cash and cash equivalents: Money market funds $ 6,853 $ — $ 6,853 $ 5,951 $ — $ 5,951 U.S. government securities 1,996 — 1,996 — — — Commercial paper — 1,498 1,498 — 5,429 5,429 Total cash equivalents $ 8,849 $ 1,498 $ 10,347 $ 5,951 $ 5,429 $ 11,380 Cash 3,671 3,990 Total cash and cash equivalents $ 14,018 $ 15,370 Short-term investments: U.S. government securities $ 5,180 $ — $ 5,180 $ 11,088 $ — $ 11,088 Corporate debt securities — 2,384 2,384 — 4,735 4,735 Commercial paper — 5,926 5,926 — 8,253 8,253 U.S. agency securities — — — — 990 990 Asset-backed securities — 1,147 1,147 — 2,187 2,187 Total short-term investments $ 5,180 $ 9,457 $ 14,637 $ 11,088 $ 16,165 $ 27,253 The Company classifies its cash equivalents and short-term investments within Level 1 or Level 2 because it uses quoted market prices or alternative pricing sources and models utilizing market observable inputs to determine their fair value. The amortized cost of cash equivalents and short-term investments approximated their fair value and there were no material realized or unrealized gains or losses, either individually or in the aggregate, and no other-than-temporary impairments. As of July 31, 2019 and January 31, 2019, the Company had no material Level 3 assets or liabilities and there have been no transfers between levels.

Customer . The Company capitalizes a significant portion of its sales commission costs as an incremental cost of obtaining customer contracts and amortizes to sales and marketing expense over an expected benefit period of five years. Amortization expense for deferred sales commissions was $0.4 million and $0.1 million for the three months ended July 31, 2019 and 2018, respectively, and $0.8 million and $0.2 million for the six months ended July 31, 2019 and 2018, respectively. To date, there have been no impairment losses related to the costs capitalized . Global In December 2018, the Company invested $1.3 million in cash to Global Telecomm Corporation, a small privately-held technology company, in exchange for an 18-month convertible promissory note, bearing interest at 10% annually. The principal and unpaid accrued interest on the promissory note will convert to shares of GTC common or preferred stock upon the occurrence of certain future events. As of July 31, 2019 and January 31, 2019, the Company did not hold any shares of GTC common or preferred stock. The Company has partnered with GTC on certain research and development and inventory procurement activities. The Company is required to consolidate the assets and liabilities of variable interest entities (“VIEs”) in which it is deemed to be the primary beneficiary. GTC is considered a VIE because, among other factors, it lacks sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties. The Company’s convertible promissory note issued by GTC represents a variable interest. However, the Company does not participate in the day-to-day operating decisions or other decisions that would allow it to control GTC, and therefore, the Company is not considered the primary beneficiary and is not required to consolidate GTC’s financial statements in Ooma’s financial statements. As of July 31, 2019 and January 31, 2019, the Company’s maximum exposure to loss was equal to the carrying value of its convertible note receivable, including accrued interest. For all periods presented, the Company held no other variable interests in VIEs. As a result of the Company’s investment, GTC is also a related party of Ooma. During the three and six months ended July 31, 2019, the Company procured certain raw material inventories from GTC that amounted to approximately $0.2 million and $0.4 million, respectively. As of July 31, 2019 and January 31, 2019, the Company recorded prepaid inventory deposits to GTC of $0.4 million and zero, respectively, included in other current assets on the condensed consolidated balance sheet. As of July 31, 2019 and January 31, 2019, the Company’s non-cancelable purchase commitments with GTC were $2.8 million and zero, respectively.

The weighted average grant date fair value of options granted during the six months ended July 31, 2019 and 2018 was $ 7.13 and $5.28 per share, respectively. Restricted Stock Units. RSU activity for the six months ended July 31, 2019 was as follows: Shares (in thousands) Weighted Average Grant-Date Fair Value Per Share Balance as of January 31, 2019 1,925 $ 10.49 Granted 960 $ 15.09 Vested (494 ) $ 9.91 Canceled (58 ) $ 11.93 Balance as of July 31, 2019 2,333 $ 12.47 Employee Stock Purchase Plan. The ESPP allows eligible employees to purchase shares of common stock at a discount through payroll deductions of up to 15 % of their eligible compensation (subject to plan limitations).

Income Tax Disclosure [Abstract]
Income Taxes	Note 9: Income Taxes The Company recorded an income tax benefit of $16,000 and $62,000 during the three months ended July 31, 2019 and 2018, respectively, and $38,000 and $131,000 during the six months ended July 31, 2019 and 2018, respectively. These income tax benefits were primarily associated with the Company’s acquisition of Voxter in March 2018. The Company continues to maintain a full valuation allowance against its deferred tax assets. As of July 31, 2019, the Company had unrecognized tax benefits of $5.2 million, none of which would currently affect the Company's effective tax rate if recognized due to the Company's deferred tax assets being fully offset by a valuation allowance. The Company does not anticipate that the amount of unrecognized tax benefits relating to tax positions existing at July 31, 2019 will significantly increase or decrease within the next twelve months. There was no interest expense or penalties related to unrecognized tax benefits recorded through July 31, 2019. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash.

Earnings Per Share [Abstract]
Basic and Diluted Net Loss Per Share	Note 10: Basic and Diluted Net Loss Per Share Basic and diluted net loss per share is calculated by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share of common stock is the same as basic net loss per share of common stock because the effects of potentially dilutive securities are anti-dilutive as the Company reported net losses for all periods presented. The following table sets forth the computation of basic and diluted net loss per share of common stock (in thousands, except share and per share data): Three Months Ended Six Months Ended July 31, 2019 July 31, 2018 July 31, 2019 July 31, 2018 Numerator Net loss $ (4,983 ) $ (3,904 ) $ (9,723 ) $ (7,589 ) Denominator Weighted-average common shares 20,849,935 19,673,658 20,667,905 19,499,677 Basic and diluted net loss per share $ (0.24 ) $ (0.20 ) $ (0.47 ) $ (0.39 ) Potentially dilutive securities of approximately 4.0

Commitments and Contingencies	Note 11: Commitments and Contingencies Purchase Commitments As of July 31, 2019 and January 31, 2019, total non-cancelable purchase commitments with the Company’s contract manufacturers and other parties were $6.0 million and $4.2 million, respectively. Legal Proceedings In addition to the litigation matters described below, from time to time, the Company may be involved in a variety of other claims, lawsuits, investigations, and proceedings relating to contractual disputes, intellectual property rights, employment matters, regulatory compliance matters, and other litigation matters relating to various claims that arise in the normal course of business. Defending such proceedings is costly and can impose a significant burden on management and employees, the Company may receive unfavorable preliminary or interim rulings in the course of litigation, and there can be no assurances that favorable final outcomes will be obtained. The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using reasonably available information. The Company develops its views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. Legal fees are expensed in the period in which they are incurred. As of July 31, 2019, the Company did not have any material loss contingencies recorded in its consolidated financial statements . Berks County Litigation On January 21, 2016, the County of Berks, Pennsylvania filed a lawsuit in the Berks County Court of Common Pleas naming the Company and 113 other telephone service providers as defendants (the “Berks County Litigation”), alleging breach of fiduciary duty, fraud, and negligent misrepresentation in connection with alleged violations of the Pennsylvania 911 Emergency Communication Services Act (“PA 911 Act”) for failure to collect from subscribers and remit certain fees pursuant to the PA 911 Act. The plaintiff seeks a declaratory judgment that the Company must comply with the PA 911 Act, compensatory and punitive damages and such other relief as the court may deem proper. The Company believes that the plaintiff’s claims are without merit since the Company has no employees, property or other indicia of a “substantial nexus” with the State of Pennsylvania. The Company intends to continue vigorously defending against this lawsuit. However, litigation is unpredictable and there can be no assurances that the Company will obtain a favorable final outcome or that it will be able to avoid unfavorable preliminary or interim rulings in the course of litigation that may significantly add to the expense of its defense and could result in substantial costs and diversion of resources. Based on the Company’s current knowledge, the Company has determined that the amount of any material loss or range of any losses that is reasonably possible to result from the Berks County Litigation is not estimable. Deep Green Wireless Litigation On June 8, 2016, plaintiff Deep Green Wireless LLC filed a complaint in the U.S. District Court for the Eastern District of Texas against Ooma, Inc., alleging infringement of U.S. Patent No. RE42,714 (the “Deep Green Wireless Patent”, and such litigation, the “Deep Green Wireless Litigation ”). The complaint seeks unspecified monetary damages, costs, attorneys’ fees and other appropriate relief. In February 2017, the Court granted the Company’s motion to transfer the case to the Northern District of California, which proceeding has been stayed pending the outcome of an inter partes review of the Deep Green Wireless Patent by the United States Patent Trial and Appeal Board (“PTAB”). On December 17, 2018, the PTAB issued its final decision regarding the claims at issue in the Deep Green Wireless Litigation, in which it determined that all challenged claims of the ‘714 patent are obvious and unpatentable. On February 19, 2019, the plaintiff filed a Notice of Appeal to the Court of Appeals for the Federal Circuit. Deep Green Wireless’ opening brief has been filed, as well as the Company’s response brief. No date has been set for oral argument. If the Federal Circuit rules in favor of the Company on appeal, we expect the Deep Green Wireless Litigation should be dismissed. Based on the Company’s current knowledge, and as confirmed by the PTAB’s final decision, Dolemba Litigation On September 4, 2018, plaintiff Scott Dolemba filed a putative class action complaint against the Company in the U.S. District Court for the Northern District of Illinois, Eastern Division, alleging violations of the Telephone Consumer Protection Act and the Illinois Consumer Fraud Act. On May 21, 2019, the Company and plaintiff settled the complaint for an immaterial amount and the complaint was voluntarily dismissed with prejudice. Oregon Tax Litigation On August 30, 2016, the Oregon Department of Revenue (the “DOR”) issued tax assessments against the Company for the Oregon Emergency Communications Tax (the “Tax”), which the DOR alleges Ooma should have collected from its subscribers in Oregon and remitted to the DOR during the period starting on January 1, 2013 and ending on March 31, 2016 (collectively, the “Assessments”). The Company believes that the Commerce Clause of the United States Constitution bars the application of the Tax and the Assessments to the Company, since the Company has no employees, property or other indicia of a “substantial nexus” with the State of Oregon. On January 17, 2019, the Regular Division of the Oregon Tax Court heard oral arguments on the parties’ cross motions for summary judgment, and no decision has been issued. The Company will continue to vigorously litigate the Complaint in pursuit of the full abatement of the Assessments. However, litigation is unpredictable and there can be no assurances that the Company will obtain a favorable fi resources. During fiscal 2019, the Company paid $0.6 million to the State of Oregon in connection with the Oregon Tax Litigation, of which $0.3 million Reid Litigation On May 23, 2019, plaintiff Valentin Reid filed a putative class action complaint (the “Reid Litigation”) against the Company in the U.S. District Court for the Southern District of New York, alleging violations of the ADA, New York State Human Rights Law, New York State Civil Rights Law, and New York City Human Rights Law. On August 28, 2019, the Company and plaintiff settled the complaint for an immaterial amount and the plaintiff is obligated to dismiss the complaint with prejudice in accordance with the terms of the settlement agreement. Securities Litigation On January 14, 2016, Michael Barnett filed a purported stockholder class action in the San Mateo County Superior Court of the State of California (Case No. CIV536959) against the Company, certain of its officers and directors, and certain of the underwriters of the Company’s IPO on July 17, 2015. Since that time two additional purported class actions making substantially the same allegations against the same defendants were filed, and on May 18, 2016, all three complaints were combined into a “consolidated complaint” filed in the same court (the “Securities Litigation”). The consolidated complaint purports to be brought on behalf of all persons who purchased shares of common stock in the Company’s IPO in reliance upon the Registration Statement and Prospectus the Company filed with the SEC. The consolidated complaint alleges that the Company and the other defendants violated the Securities Act of 1933, as amended (the “Securities Act”) by issuing the Registration Statement and Prospectus, which the plaintiffs allege contained material misstatements and omissions in violation of Sections 11, 12(a)(2) and 15 of the Securities Act. The plaintiffs seek class certification, compensatory damages, attorneys’ fees and costs, rescission or a rescissory measure of damages, equitable and/or injunctive relief, and such other relief as the court may deem proper. On November 29, 2017, the Superior Court dismissed the claims that were based on Sections 12(a)(2) and 15 of the Securities Act with prejudice. On May 30, 2019, the parties filed with the Court a Stipulation of Settlement. Under the terms of the proposed settlement, the Company’s directors’ and officers’ liability insurers will deposit $8.65 million into a settlement fund for payment to class members, plaintiff’s attorneys’ fees and costs of administering the settlement. The proposed settlement must be approved by the Court before becoming effective. The Stipulation of Settlement contains no admissions of wrongdoing, and the Company and the other defendants have maintained and continue to deny liability and wrongdoing of any kind with respect to the class action claims. If the Court grants final approval of the Stipulation of Settlement, the Court will dismiss the class action lawsuit with prejudice and the plaintiff will be deemed to have released all claims against the Company and all other defendants relating to the allegations in the class action. The Company can provide no assurance that the Court will approve the Stipulation of Settlement. Based on the Company’s current knowledge, it believes that if the settlement is approved, the amount of any further probable loss to be paid by the Company will be immaterial. Indemnification The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for certain losses suffered or incurred by the indemnified party. In some cases, the term of these indemnification agreements is perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future but have not yet been made. The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has director and officer insurance coverage that reduces the Company’s exposure and enables the Company to recover a portion of any future amounts paid. To date the Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with such indemnifications has been recorded to date.

Business Acquisition	Note 12: Business Acquisition On May 24, 2019, the Company completed its acquisition of Broadsmart, a cloud-based UCaaS solutions provider based in Florida. T he aggregate fair value consideration transferred for Broadsmart was in cash, of which approximately $0.9 million will be held in escrow for a period of up to two years. The fair values of assets acquired and liabilities assumed as of the date of acquisition was as follows (in thousands): Fair Value Cash $ 649 Accounts receivable 1,003 Other current and non-current assets 639 Intangible assets 6,107 Goodwill 366 Accounts payable and other liabilities (1,043 ) Net assets acquired $ 7,721 Intangible assets acquired consisted of customer relationships of $5.8 million and trade names of $0.3 million. Customer relationships represented the estimated fair values of the underlying relationships with Broadsmart’s customer base and have an estimated useful life of seven years as of the date of acquisition. The goodwill recognized was attributable to the assembled workforce and expanded market opportunities when integrating Broadsmart’s offerings with Ooma Business. The Company made an election under Section 338(h)(10) of the Internal Revenue Code, which resulted in the acquisition being treated as an asset purchase for income tax purposes. Th The operating results of the acquired company have been included in the Company's consolidated financial statements from the date of acquisition. Actual and pro forma results of operations for the Broadsmart acquisition have not been presented because it did not have a material impact on the Company's consolidated results of operations. Acquisition-related transaction costs charged to expense during the three and six months ended July 31, 2019 were approximately $0.2 million.

Overview and Basis of Presentation (Policies)	6 Months Ended
	Jul. 31, 2019
Accounting Policies [Abstract]
Principles of Presentation and Consolidation	Principles of Presentation and Consolidation These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2019 (“Annual Report”). These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect The condensed consolidated financial statements include accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the Company’s condensed consolidated financial statements and notes thereto. Significant estimates include, but are not limited to, those related to revenue recognition, inventory valuation, valuation of goodwill and intangible assets, deferred sales commissions, operating lease assets and liabilities, regulatory fees and indirect tax accruals, loss contingencies, stock-based compensation, income taxes (including valuation allowances) and fair value measurements. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. These estimates are based on information available as of the date of the condensed consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates.
Comprehensive Loss	Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the condensed consolidated statements of operations and differences were not material. Therefore, the condensed consolidated statements of comprehensive loss have been omitted.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Leases . On February 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) which superseded the guidance in Topic 840 and required the Company to recognize operating leased assets and corresponding liabilities on the balance sheet and to provide enhanced disclosures. The Company adopted Topic 842 using the modified retrospective transition method by applying the new standard to all leases existing at the date of initial adoption and not restating comparative periods. The Company elected the package of practical expedients, which among other things, allowed it to carry forward its historical lease classification and its assessment of whether any existing leases as of the date of adoption are or contain leases. Adoption on February 1, 2019 resulted in the recognition of $4.1 million of operating right-of-use “ROU” assets and $4.3 million of operating lease liabilities on the condensed consolidated balance sheet, with no adjustment to accumulated deficit. The difference of $0.2 million represented deferred rent for leases that existed as of the date of adoption, which was an offset to the opening balance of ROU assets. Adoption of the new standard did not materially impact the Company’s consolidated statements of operations, consolidated statements of stockholders’ equity and consolidated statements of cash flows. The Company has implemented policies, processes and controls to support the standard's measurement and disclosure requirements. See Significant Accounting Policies – Leases Operating Leases Stock-based compensation. The Company adopted ASU 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting in the first quarter of fiscal 2020, which expanded the scope of Topic 718 to include and simplify financial reporting for non-employee stock-based payments. Under the amended standard, most of the guidance on stock compensation for non-employees became aligned with the requirements for employees. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.
Significant Accounting Policies - Leases	Significant Accounting Policies – Leases On February 1, 2019, the Company adopted Topic 842 using the modified retrospective transition method by applying the new standard to all leases existing at the date of initial adoption. Comparative prior period amounts have not been adjusted and continue to be reported in accordance with historical accounting under Topic 840. Under Topic 842, the Company determines if an arrangement is a lease at inception. The Company’s leases primarily consist of real property and are classified as operating leases. The Company does not have any finance leases nor material arrangements as a lessor. ROU assets and lease liabilities are recognized at the lease commencement date based upon the present value of the remaining lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease. Lease terms may include options to renew or extend when it is reasonably certain that the option will be exercised. Lease agreements that contain both lease and non-lease components are accounted for as a single component. Short-term leases with an initial term of twelve months or less are not recorded on the balance sheet.
