Nature of Business and Operations | |
Nature of Business and Operations | Note 1. Nature of Business and Operations Tactile Systems Technology, Inc. (“we,” “us,” and “our”) is the sole manufacturer and distributor of the Flexitouch and Entre systems, medical devices that help control symptoms of lymphedema, a chronic and progressive medical condition, and the Actitouch system, a medical device used to treat venous leg ulcers and chronic venous insufficiency. We provide our products for use in the home and sell them through vascular, wound and lymphedema clinics throughout the United States. We do business as “Tactile Medical.” We were originally incorporated in Minnesota under the name Tactile Systems Technology, Inc. on January 30, 1995. During 2006, we established a merger corporation and subsequently, on July 21, 2006, merged with and into this merger corporation, resulting in us being reincorporated as a Delaware corporation. The resulting corporation assumed the name Tactile Systems Technology, Inc. In September 2013, we began doing business as “Tactile Medical.” In connection with preparing for our initial public offering, our board of directors and stockholders approved a 1-for-2.820044 reverse stock split of our capital stock. The reverse stock split became effective in June 2016. On August 2, 2016 we closed the initial public offering of our common stock, which resulted in the sale of 4,120,000 shares of our common stock at a public offering price of $10.00 per share. We received net proceeds from the initial public offering of approximately $35.4 million, after deducting underwriting discounts and approximately $2.9 million of transaction expenses. In connection with the closing of the initial public offering, all of our outstanding redeemable convertible preferred stock automatically converted to common stock on August 2, 2016. At August 2, 2016, we did not have any redeemable convertible preferred stock issued or outstanding. Our business is affected by seasonality. In the first quarter of each year, when most patients have started a new insurance year and have not yet met their annual out-of-pocket payment obligations, we experience substantially reduced demand for our products. We typically experience higher sales in the third and fourth quarters as a result of patients having paid their annual insurance deductibles in full, thereby reducing their out-of-pocket costs for our products, and because patients often spend the remaining balances in their healthcare flexible spending accounts at that time. This seasonality applies only to purchases of our products by patients covered by commercial insurance and is not relevant to Medicare, Medicaid, or the Veterans Administration, as those payers either do not have plans that have declining deductibles over the course of the plan year or do not have plans that include patient deductibles for purchases of our products. |

Basis of Presentation | Note 2. Basis of Presentation Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. We have reclassified certain prior year amounts to conform to the current year’s presentation. The results for the six months ended June 30, 2018 are not necessarily indicative of results to be expected for the year ending December 31, 2018, or for any other interim period or for any future year. The condensed consolidated interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Tactile Systems Technology, Inc. and its wholly owned subsidiary, Swelling Solutions, Inc. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Comprehensive Income Comprehensive income reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Our comprehensive income represents net income adjusted for unrealized gains and losses on available-for-sale marketable securities. JOBS Act Accounting Election As an emerging growth company under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), we currently are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. We elected to take advantage of the extended transition period for adopting new or revised accounting standards that have different effective dates for public and private companies until such time as those standards apply to private companies. However, as of the last business day of our second fiscal quarter of 2018, the market value of our common stock that was held by non-affiliates exceeded $700 million, and as a result, we will no longer qualify as an emerging growth company as of December 31, 2018. Therefore, after that date, we will no longer be able to take advantage of the extended transition period for adopting new or revised accounting standards. |

Summary of Significant Accounting Policies | |
Summary of Significant Accounting Policies | Note 3. Summary of Significant Accounting Policies Significant Accounting Policies During the six months ended June 30, 2018 there were no material changes in our significant accounting policies. See Note 3 - “Summary of Significant Accounting Policies” to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2017 for information regarding our significant accounting policies. Recent Accounting Pronouncements We currently are an “emerging growth company” as defined by the JOBS Act. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, (the “Securities Act”), for complying with new or revised accounting standards. In other words, an emerging growth company can selectively delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We elected to avail ourselves of this exemption and, as a result, our financial statements may not be comparable to the financial statements of issuers that are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies. Section 107 of the JOBS Act provides that we can elect to opt out of the extended transition period at any time, which election is irrevocable. However, as of the last business day of our second fiscal quarter of 2018, the market value of our common stock that was held by non-affiliates exceeded $700 million, and as a result, we will no longer qualify as an emerging growth company as of December 31, 2018 and will no longer be able to take advantage of the extended transition period. Therefore, as of December 31, 2018, we will be required to adopt new or revised accounting standards when they are applicable to public companies that are not emerging growth companies. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “ Revenue from Contracts with Customers .” The new section replaces Section 605, “ Revenue Recognition ,” and creates modifications to various other revenue accounting standards for specialized transactions and industries. The section is intended to conform revenue accounting principles with concurrently issued International Financial Reporting Standards to reconcile previously differing treatment between U.S. practices and those of the rest of the world and to enhance disclosures related to disaggregated revenue information. The updated guidance will be effective for us for our interim and annual reporting periods ending on or after December 31, 2018 due to the recent determination of our upcoming change in filing status. As a result, we have commenced project planning for our implementation, which has included engaging an accounting firm to assist us. We have not yet made a determination on our transition method, nor have we determined whether this standard will have a material impact on our financial statements. In February 2016, the FASB issued ASU 2016-02, “ Leases ” (Topic 842), which supersedes the existing guidance for lease accounting, “ Leases” (Topic 840). ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset for all leases. Lessor accounting remains largely unchanged. The amendments in this ASU will be effective for us for interim and annual periods beginning after December 15, 2018. ASU 2016-02 requires a modified retrospective approach for all leases existing at, or entered into after, the date of initial adoption, with an option to elect to use certain transition relief. Due to the recent determination of our upcoming change in filing status, which has accelerated our required implementation date of this standard, we have commenced project planning for our implementation. We are currently evaluating whether this standard will have a material impact on our financial statements. In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments — Credit Losses ,” to require the measurement of expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable forecasts. The ASU will be effective for us for interim and annual periods beginning after December 15, 2019. Therefore, we plan to further evaluate the anticipated impact of the adoption of this ASU on our consolidated financial statements in future periods. In August 2016, the FASB issued ASU No. 2016-15, “ Statement of Cash Flows (Topic 230) — Classification of Certain Cash Receipts and Cash Payments ,” to provide clarity on how certain cash receipt and cash payment transactions are presented and classified within the statement of cash flows. The ASU will be effective for us for interim and annual periods beginning after December 15, 2018. We do not anticipate any material impact on our consolidated financial statements in future periods as a result of the adoption of this ASU. In January 2017, the FASB issued ASU No. 2017-01 “ Business Combinations (Topic 805) — Clarifying the Definition of a Business ,” to revise the definition of a business and provide new guidance to assist in the evaluation of transactions as either asset acquisitions (disposals) or business acquisitions (disposals). We currently are an “emerging growth company” as defined by the JOBS Act and this ASU will become effective for us on December 31, 2018 when we no longer qualify for that status. We have elected early adoption for interim transactions that have not previously been included in issued financial statements, which is permitted under this standard. The adoption of this standard did not have a material impact on our consolidated financial statements. |

Asset Acquisitions | Note 4. Asset Acquisition On May 22, 2018, we acquired certain assets and the intellectual property of Wright Therapy Products, Inc. (“WTP”) for total consideration of approximately $875,000 plus a potential earn-out. The earn-out is based on certain revenue metrics over the seven-month period beginning June 30, 2018 and is capitalized to intangible assets. The assets include the rights to a portfolio of thirty-one issued and pending patents that include intellectual property related to WTP’s pneumatic compression therapy devices and five related trademarks, as well as certain customer accounts. Due to the nature of these patents and related trademarks, as well as our planned use, they have been classified as defensive intangible assets on the balance sheet. The acquisition was recorded as an asset acquisition, and an allocation of the purchase price, based on relative fair value, has been completed as reflected below: Gross Weighted-Average (Dollars in thousands) Carrying Amount Amortization Period Defensive intangible assets $ 787.8 7 years Customer accounts 87.5 5 years Total $ 875.3 |

Commitments and Contingencies | Note 8. Commitments and Contingencies Lease Obligations In March 2008, we entered into a non-cancelable operating lease agreement for building space for our corporate headquarters that provides for monthly rent, real estate taxes and operating expenses. This lease was subsequently extended to July 31, 2021. In July 2016, we entered into a non-cancelable operating lease agreement for building space to accommodate the relocation of our manufacturing, quality, engineering and research and development functions. This lease agreement extends through November 2021 and provides for monthly rent, real estate taxes and operating expenses. Rent expense was $0.4 million and $0.3 million for the three months ended June 30, 2018 and 2017, respectively, and $0.7 million and $0.5 million for the six months ended June 30, 2018 and 2017, respectively. In July 2016, we entered into a fleet vehicle lease program for certain members of our field sales organization. At June 30, 2018, we had 17 vehicles with future lease obligations under this program. We also have operating lease agreements for certain computer and office equipment that expire in 2021. The leases provide an option to purchase the related equipment at fair market value at the end of the lease. Future base minimum lease payments for all lease obligations are expected to be as follows for the years ending December 31: Computer/Office Fleet Vehicle (In thousands) Buildings Equipment Program Total 2018 (July 1 - December 31) $ 405 $ 28 $ 82 $ 515 2019 866 51 38 955 2020 870 34 — 904 2021 592 3 — 595 2022 — — Thereafter — — — — Total $ 2,733 $ 116 $ 120 $ 2,969 Major Vendors We had purchases from two major vendors that accounted for 44% and 39% of our total purchases for the three and six months ended June 30, 2018, respectively. We had purchases from three major vendors that accounted for 36% of our total purchases for each of the three and six months ended June 30, 2017. Purchase Commitments We issued purchase orders in 2017 totaling $5.9 million for items that we expect to receive between August and December of 2018. Employment Agreements We have entered into employment agreements with certain of our officers. The agreements provide for payment of severance ranging from 9 to 15 months of then-current annualized base salary in the event of termination by us without cause or by the employee for good reason or, in the case of two of the officers, death, disability, or as a result of a qualifying termination after a change in control. The agreements also provide for payment of an amount equal to 9 to 15 months of the then-current annual target bonus in the event of termination by us without cause or by the employee for good reason, or, in the case of two of the officers, death, disability, or as a result of a qualifying termination after a change in control. In addition, the agreements provide for the vesting of certain equity compensation through the date of termination in the event of termination by us without cause or by the employee for good reason. Retirement Plan We maintain a 401(k) retirement plan for our employees in which eligible employees can contribute a percentage of their pre-tax compensation. We may also make discretionary contributions to the 401(k) plan. We made contributions of $58,000 and $48,000 for the three months ended June 30, 2018 and 2017, respectively, and $111,000 and $93,000 for the six months ended June 30, 2018 and 2017, respectively. |

Stockholders' Equity | |
Stockholders' Equity | Note 9. Stockholders' Equity We completed an initial public offering of our common stock on August 2, 2016, in which we sold 4,120,000 shares of our common stock at a public offering price of $10.00 per share. Immediately prior to the completion of the initial public offering, all then-outstanding shares of our Series A and Series B preferred stock were converted into 5,924,453 shares of our common stock. Our Series A preferred stock converted to Stock-Based Compensation Our 2016 Equity Incentive Plan (the “2016 Plan”) authorizes us to grant stock options, stock appreciation rights, restricted stock, stock units and other stock-based awards to employees, non-employee directors and certain consultants and advisors. There were up to 4,800,000 shares of our common stock initially reserved for issuance pursuant to the 2016 Plan. The 2016 Plan provides that the number of shares reserved and available for issuance under the 2016 Plan will automatically increase annually on January 1 of each calendar year, commencing in 2017 and ending on and including January 1, 2026, by an amount equal to the lesser of: (a) 5% of the number of common shares of stock outstanding as of December 31 of the immediately preceding calendar year, or (b) 2,500,000 shares; provided, however, that our Board of Directors may determine that any annual increase be a lesser number. In addition, all awards granted under our 2007 Omnibus Stock Plan and our 2003 Stock Option Plan that were outstanding when the 2016 Plan became effective and that are forfeited, expire, are cancelled, are settled for cash or otherwise not issued, will become available for issuance under the 2016 Plan. Effective January 1, 2017, 841,686 shares were added to the 2016 Plan, as available for issuance thereunder, pursuant to the automatic increase feature of the 2016 Plan. Effective January 1, 2018, 892,318 shares were added to the 2016 Plan, as available for issuance thereunder, pursuant to the automatic increase feature of the 2016 Plan. As of June 30, 2018, 5,230,344 shares were available for future grant pursuant to the 2016 Plan. Upon adoption and approval of the 2016 Plan, all of our previous equity incentive compensation plans were terminated. However, existing awards under those plans continue to vest in accordance with the original vesting schedules and will expire at the end of their original terms. We recorded stock-based compensation expense of $1.8 million and $1.2 million for the three months ended June 30, 2018 and 2017, respectively, and $3.3 million and $2.1 million for the six months ended June 30, 2018 and 2017, respectively. This expense was allocated as follows: Three Months Ended Six Months Ended June 30, June 30, (In thousands) 2018 2017 2018 2017 Cost of goods sold $ 69 $ 49 $ 109 $ 98 Sales and marketing expenses 786 354 1,438 669 Research and development expenses 25 21 94 44 Reimbursement, general and administrative expenses 897 756 1,617 1,326 Total stock-based compensation expense $ 1,777 $ 1,180 $ 3,258 $ 2,137 Stock Options Stock options issued to participants other than non-employees vest over three or four years and typically have a contractual term of seven or ten years. Annually, stock options are granted to our non-employee directors on the date of the annual meeting of stockholders and vest in full on the earlier of one year after the date of grant or on the date of the next year’s annual meeting of stockholders. These options have a contractual term of seven years. Stock-based compensation expense included in our Condensed Consolidated Statements of Operations for stock options was $0.5 million and $0.3 million for the three months ended June 30, 2018 and 2017, respectively, and $1.0 million and $0.5 million for the six months ended June 30, 2018 and 2017, respectively. At June 30, 2018, there was approximately $4.9 million of total unrecognized pre-tax stock option expense under our equity compensation plans, which is expected to be recognized on a straight-line basis over a weighted-average period of 2.8 years. Stock option activity for the six months ended June 30, 2018 is summarized as follows: Weighted- Weighted- Average Average Aggregate Options Exercise Price Remaining Intrinsic (In thousands except share, per share and years data) Outstanding Per Share (1) Contractual Life Value (2) Balance at December 31, 2017 1,487,720 $ 8.41 6.2 years $ 29,611 Granted 110,521 $ 35.01 Exercised (265,139) $ 2.16 $ 9,842 Forfeited (20,851) $ 20.91 Balance at June 30, 2018 1,312,251 $ 11.72 6.3 years $ 52,860 Options exercisable at June 30, 2018 806,689 $ 3.67 4.9 years $ 38,989 (1) The exercise price of each option granted during the period shown was equal to the market price of the underlying stock on the date of grant. (2) The aggregate intrinsic value of options exercised represents the difference between the exercise price of the option and the closing stock price of our common stock on the date of exercise. The aggregate intrinsic value of options outstanding represents the difference between the exercise price of the option and the closing stock price of our common stock on the last trading day of the period. Options exercisable of 1,152,453 as of June 30, 2017 had a weighted-average exercise price of $1.92 per share. Stock-Settled Restricted Stock Units We have granted both time-based and performance-based stock-settled restricted stock units to certain participants under the 2016 Plan. Time-based stock-settled restricted stock units granted under the 2016 Plan vest over one to three years. These awards are stock-settled with common shares. Stock-based compensation expense included in our Condensed Consolidated Statements of Operations for time-based stock-settled restricted stock units was $0.9 million and $0.7 million for the three months ended June 30, 2018 and 2017, respectively, and $1.7 million and $1.2 million for the six months ended June 30, 2018 and 2017, respectively. As of June 30, 2018, there was approximately $6.0 million of total unrecognized pre-tax compensation expense related to outstanding time-based stock-settled restricted stock units that is expected to be recognized over a weighted-average period of 2.0 years. Our time-based stock-settled restricted stock unit activity for the six months ended June 30, 2018 was as follows: Weighted- Average Grant Aggregate Units Date Fair Value Intrinsic (In thousands except unit and per unit data) Outstanding Per Unit Value (1) Balance at December 31, 2017 441,507 $ 16.38 $ 12,795 Granted 86,416 $ 33.70 Vested (166,746) $ 21.96 Cancelled (16,901) $ 20.02 Balance at June 30, 2018 344,276 $ 27.72 $ 17,902 Deferred and unissued at June 30, 2018 (2) 3,147 $ 27.74 $ 164 (1) The aggregate intrinsic value of stock-settled restricted stock units outstanding was based on our closing stock price on the last trading day of the period. (2) For the six months ended June 30, 2018, there were 934 restricted stock units granted to non-employee directors in lieu of their quarterly cash retainer payments. These restricted stock units were fully vested upon grant and represent the right to receive one share of common stock, per unit, upon the earlier of the directors’ termination of service as a director of ours or the occurrence of a change of control of us. These restricted stock units are included in the “Granted” line in the table above and are also included in the “Vested” line in the table above due to their being fully vested upon grant. As of June 30, 2018, there were 3,147 outstanding restricted stock units that have been granted to non-employee directors in lieu of their quarterly director retainer payments. These restricted stock units are not included in the “Balance at June 30, 2018” line in the table above because they are fully vested. In February 2018, we granted 67,982 performance-based stock-settled restricted stock units (“PSUs”), which represents the target number of PSUs under these awards, to certain participants under the 2016 Plan. These PSUs have both performance-based and time-based vesting features. The PSUs will be earned if and to the extent performance goals based on revenue and adjusted EBITDA are achieved in 2019. The number of PSUs earned will depend on the level at which the performance targets are achieved, and can range from 50% of target if threshold performance is achieved and up to 150% of target if maximum performance is achieved. One third of the earned PSUs will vest on the date the Compensation and Organization Committee certifies the number of PSUs earned, and the remaining two thirds of the earned PSUs will vest on the first anniversary of that certification date. All earned and vested PSUs will be settled in shares of common stock. Stock-based compensation expense included in our Condensed Consolidated Statements of Operations for PSUs was $0.2 million and $0.3 million for the three and six months ended June 30, 2018, respectively, and $0 for the same periods in 2017. As of June 30, 2018, there was approximately $1.9 million of total unrecognized pre-tax compensation expense related to outstanding PSUs that is expected to be recognized over a weighted average period of 2.7 years. Employee Stock Purchase Plan Our employee stock purchase plan (“ESPP”), which was approved by our Board of Directors on April 27, 2016 and by our stockholders on June 20, 2016, allows participating employees to purchase shares of our common stock at a discount through payroll deductions. The plan is available to all our employees and employees of participating subsidiaries. Participating employees may purchase common stock, on a voluntary after-tax basis, at a price equal to 85% of the lower of the closing market price per share of our common stock on the first or last trading day of each stock purchase period. The plan provides for six-month purchase periods, beginning on May 16 and November 16 of each calendar year. A total of 1.6 million shares of common stock was initially reserved for issuance under the ESPP, and this share reserve will automatically be supplemented each January 1, commencing in 2017 and ending on and including January 1, 2026, by an amount equal to the least of (1) 1% of the shares of our common stock outstanding on the immediately preceding December 31, (2) 500,000 shares or (3) such lesser amount as our Board of Directors may determine. Effective January 1, 2018, 178,463 shares were added to the ESPP, as available for issuance thereunder, pursuant to the automatic increase feature of the plan. On May 15, 2018, 63,578 shares were purchased under the ESPP, utilizing $1.4 million of employee contributions. As of June 30, 2018, 1,576,090 shares were available for future issuance under the ESPP. We recognized stock-based compensation expense associated with the ESPP of $ 0.1 million and $0.2 million for the three months ended June 30, 2018 and 2017, respectively, and $ 0.3 million and $0.4 million for the six months ended June 30, 2018 and 2017, respectively. |

Income Taxes | |
Income Taxes | Note 10. Income Taxes We record our interim provision for income taxes by applying our estimated annual effective tax rate to our year-to-date pre-tax income and adjusting for discrete tax items recorded in the period. Deferred income taxes result from temporary differences between the reporting of amounts for financial statement purposes and income tax purposes. These differences relate primarily to different methods used for income tax reporting purposes, including for depreciation and amortization, warranty and vacation accruals, and deductions related to allowances for doubtful accounts receivable and inventory reserves. Our provision for income taxes included current federal and state income tax expense, as well as deferred federal and state income tax expense. The effective tax rate for the three months ended June 30, 2018 was a benefit of 78.3%, compared to a benefit of 376.5% for the three months ended June 30, 2017. The primary driver of the change in the effective tax rate was a decrease in the tax benefits related to tax-deductible stock-based compensation activity, combined with an increase in our pre-tax book income as compared to the same prior year period. Significant tax deductions in both the current and prior year period included benefits with respect to the vesting of restricted stock units, exercises of non-qualified stock options, and disqualifying dispositions of incentive stock options and ESPP shares. We recorded an income tax benefit of $1.1 million and $3.0 million for the three months ended June 30, 2018 and 2017, respectively. The effective tax rate for the six months ended June 30, 2018 was 958.9%, compared to 209.7% for the six months ended June 30, 2017. The primary driver of the change in the effective tax rate was a decrease in the tax benefits related to tax-deductible stock-based compensation activity, combined with a decrease in our pre-tax book loss as compared to the same prior year period. We recorded an income tax benefit of $2.8 million and an income tax benefit of $4.4 million for the six months ended June 30, 2018 and 2017, respectively. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the “more likely than not” threshold, the amount recognized in the condensed consolidated financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. As of June 30, 2018 we had an unrecognized tax benefit ("UTB") with respect to state income taxes of approximately $57,000. The UTB represents taxes, interest, and penalties related to un-filed and unpaid income taxes in multiple state jurisdictions. We are continuing actions to settle these outstanding liabilities. To date, we have settled a significant portion of our outstanding liabilities through voluntary settlements with various state taxing authorities. We are currently under examination by the Internal Revenue Service for our 2016 federal tax return. We are not currently under examination for income taxes by any other taxing jurisdictions. In the event of any future tax assessments, we have elected to record the income taxes and any related interest and penalties as income tax expense on our statement of operations. |

Fair Value Measurements
Fair Value Measurements | 6 Months Ended |

Fair Value Measurements | |
Fair Value Measurements | Note 12. Fair Value Measurements We determine the fair value of our assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. We use a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1). The next highest priority is based on quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in non-active markets or other observable inputs (Level 2). The lowest priority is given to unobservable inputs (Level 3). The following provides information regarding fair value measurements for our cash equivalents and marketable securities as of June 30, 2018 and December 31, 2017 according to the three-level fair value hierarchy: As of June 30, 2018 Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable Assets Inputs Inputs (In thousands) (Level 1) (Level 2) (Level 3) Total Recurring Fair Value Measurements: Money market mutual funds $ 11,614 $ — $ — $ 11,614 U.S. government and agency obligations 8,864 8,958 — 17,822 Corporate debt securities — 5,980 — 5,980 Total $ 20,478 $ 14,938 $ — $ 35,416 As of December 31, 2017 Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable Assets Inputs Inputs (In thousands) (Level 1) (Level 2) (Level 3) Total Recurring Fair Value Measurements: Money market mutual funds $ 9,212 $ — $ — $ 9,212 U.S. government and agency obligations 1,000 10,941 — 11,941 Corporate debt securities — 8,003 — 8,003 Total $ 10,212 $ 18,944 $ — $ 29,156 During the six months ended June 30, 2018, there were no transfers within the three-level hierarchy. A significant transfer is recognized when the inputs used to value a security have been changed, which merits a transfer between the disclosed levels of the valuation hierarchy. The fair values for our money market mutual funds, U.S. government and agency obligations and corporate debt securities are determined based on valuations provided by external investment managers who obtain them from a variety of industry standard data providers. The carrying amounts of financial instruments such as cash equivalents, accounts receivable, other assets, accounts payable, accrued expenses and other liabilities approximate their related fair values due to the short-term maturities of these items. Non-financial assets, such as equipment and leasehold improvements, and intangible assets are subject to non-recurring fair value measurements if they are deemed impaired. We had no re-measurements of non-financial assets to fair value in the six months ended June 30, 2018. |

Subsequent Events | Note 13. Subsequent Event On August 3, 2018, we entered into a Credit Agreement (the “Credit Agreement”) with the lenders from time to time party thereto, and Wells Fargo Bank, National Association. The Credit Agreement provides for a new $10,000,000 revolving credit facility. The revolving credit facility expires on August 3, 2021. Subject to satisfaction of certain conditions, we may increase the amount of the revolving loans available under the Credit Agreement and/or add one or more term loan facilities in an amount not to exceed $25,000,000 in the aggregate, such that the total aggregate principal amount of loans available under the Credit Agreement (including under the revolving credit facility) does not exceed $35,000,000. Amounts drawn under the revolving credit facility will bear interest, at our option, at a rate equal to (a) the highest of (i) the prime rate, (ii) the federal funds rate plus 0.50% and (iii) LIBOR for an interest period of one month plus 1% (the “Base Rate”) plus an applicable margin or (b) LIBOR plus the applicable margin. The applicable margin is 0.40% to 1.15% on loans bearing interest at the Base Rate and 1.40% to 2.15% on loans bearing interest at LIBOR, in each case depending on our consolidated total leverage ratio. Undrawn portions of the revolving credit facility are subject to an unused line fee at a rate per annum from 0.200% to 0.275%, depending on our consolidated total leverage ratio. Our obligations under the Credit Agreement are secured by a security interest in substantially all of our assets and those of our subsidiaries and will also be guaranteed by our subsidiaries. The Credit Agreement limits our ability to make capital expenditures during a fiscal year in excess of the amounts set forth in the Credit Agreement, and requires that we (i) not permit, as of the last day of each fiscal quarter, our consolidated total leverage ratio to exceed 3.00 to 1.00 and (ii) maintain minimum cash and cash equivalents, measured on the last day of each fiscal quarter, of not less than $7,500,000 (subject to a temporary reduction to $5,000,000 for the two fiscal quarters immediately following a permitted acquisition). The Credit Agreement also contains certain other restrictions and covenants, which, among other things, restrict our ability to acquire or merge with another entity, dispose of our assets, make investments, loans or guarantees, incur additional indebtedness, create liens or other encumbrances, or pay dividends or make other distributions. Amounts due under the Credit Agreement may be accelerated upon an Event of Default (as defined in the Credit Agreement), such as breach of a representation, covenant or agreement of ours, defaults with respect to certain of our other material indebtedness or the occurrence of bankruptcy if not otherwise waived or cured. We may use the proceeds from advances under the revolving credit facility (i) to finance capital expenditures, (ii) to pay fees, commissions and expenses in connection with the Credit Agreement and (iii) for working capital and general corporate purposes. |

All intercompany balances and transactions have been eliminated in 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 reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |

JOBS Act Accounting Election | JOBS Act Accounting Election As an emerging growth company under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), we currently are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. We elected to take advantage of the extended transition period for adopting new or revised accounting standards that have different effective dates for public and private companies until such time as those standards apply to private companies. However, as of the last business day of our second fiscal quarter of 2018, the market value of our common stock that was held by non-affiliates exceeded $700 million, and as a result, we will no longer qualify as an emerging growth company as of December 31, 2018. Therefore, after that date, we will no longer be able to take advantage of the extended transition period for adopting new or revised accounting standards. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements We currently are an “emerging growth company” as defined by the JOBS Act. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, (the “Securities Act”), for complying with new or revised accounting standards. In other words, an emerging growth company can selectively delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We elected to avail ourselves of this exemption and, as a result, our financial statements may not be comparable to the financial statements of issuers that are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies. Section 107 of the JOBS Act provides that we can elect to opt out of the extended transition period at any time, which election is irrevocable. However, as of the last business day of our second fiscal quarter of 2018, the market value of our common stock that was held by non-affiliates exceeded $700 million, and as a result, we will no longer qualify as an emerging growth company as of December 31, 2018 and will no longer be able to take advantage of the extended transition period. Therefore, as of December 31, 2018, we will be required to adopt new or revised accounting standards when they are applicable to public companies that are not emerging growth companies. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “ Revenue from Contracts with Customers .” The new section replaces Section 605, “ Revenue Recognition ,” and creates modifications to various other revenue accounting standards for specialized transactions and industries. The section is intended to conform revenue accounting principles with concurrently issued International Financial Reporting Standards to reconcile previously differing treatment between U.S. practices and those of the rest of the world and to enhance disclosures related to disaggregated revenue information. The updated guidance will be effective for us for our interim and annual reporting periods ending on or after December 31, 2018 due to the recent determination of our upcoming change in filing status. As a result, we have commenced project planning for our implementation, which has included engaging an accounting firm to assist us. We have not yet made a determination on our transition method, nor have we determined whether this standard will have a material impact on our financial statements. In February 2016, the FASB issued ASU 2016-02, “ Leases ” (Topic 842), which supersedes the existing guidance for lease accounting, “ Leases” (Topic 840). ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset for all leases. Lessor accounting remains largely unchanged. The amendments in this ASU will be effective for us for interim and annual periods beginning after December 15, 2018. ASU 2016-02 requires a modified retrospective approach for all leases existing at, or entered into after, the date of initial adoption, with an option to elect to use certain transition relief. Due to the recent determination of our upcoming change in filing status, which has accelerated our required implementation date of this standard, we have commenced project planning for our implementation. We are currently evaluating whether this standard will have a material impact on our financial statements. In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments — Credit Losses ,” to require the measurement of expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable forecasts. The ASU will be effective for us for interim and annual periods beginning after December 15, 2019. Therefore, we plan to further evaluate the anticipated impact of the adoption of this ASU on our consolidated financial statements in future periods. In August 2016, the FASB issued ASU No. 2016-15, “ Statement of Cash Flows (Topic 230) — Classification of Certain Cash Receipts and Cash Payments ,” to provide clarity on how certain cash receipt and cash payment transactions are presented and classified within the statement of cash flows. The ASU will be effective for us for interim and annual periods beginning after December 15, 2018. We do not anticipate any material impact on our consolidated financial statements in future periods as a result of the adoption of this ASU. In January 2017, the FASB issued ASU No. 2017-01 “ Business Combinations (Topic 805) — Clarifying the Definition of a Business ,” to revise the definition of a business and provide new guidance to assist in the evaluation of transactions as either asset acquisitions (disposals) or business acquisitions (disposals). We currently are an “emerging growth company” as defined by the JOBS Act and this ASU will become effective for us on December 31, 2018 when we no longer qualify for that status. We have elected early adoption for interim transactions that have not previously been included in issued financial statements, which is permitted under this standard. The adoption of this standard did not have a material impact on our consolidated financial statements. |
