Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	​ (2) Summary of Significant Accounting Policies ​ (a) Basis of Presentation, Consolidation and Use of Estimates ​ These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. ​ The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Future events and their effects cannot be predicted with certainty; accordingly, accounting estimates require the exercise of judgment. In March 2020, the World Health Organization declared the outbreak of the novel coronavirus disease (“COVID-19”) as a pandemic which ​ Beginning in fiscal 2020, the Company simplified the presentation of revenue and cost of revenues on its Unaudited Consolidated Statements of Operations and Comprehensive Income. The line items “Recurring fees” and “Implementation services and other” have been combined into one revenue line: “Recurring and other revenue”. Likewise, the line items “Cost of revenues – recurring revenues” and “Cost of revenues – implementation services and other” have been combined into one line: “Cost of revenues”. The Company changed the presentation of revenue and cost of revenues as Implementation services and other has become a smaller component of its overall revenue mix due to the human capital management (“HCM”) suite becoming a larger part of the portfolio. Previously reported results for the three and nine months ended March 31, 2019 have been reclassified to conform to the current presentation. ​ (b) Interim Unaudited Consolidated Financial Information ​ The accompanying unaudited consolidated financial statements and notes have been prepared in accordance with GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the Company’s financial position, results of operations, changes in stockholders’ equity and cash flows. The results of operations for the three and nine months ended March 31, 2020 are not necessarily indicative of the results for the full year or the results for any future periods. The financial impacts from the COVID-19 pandemic became more observable in the latter half of March 2020. As a result, the impact of the COVID - 19 pandemic will not be fully known or reflected in the Company’s results of operations and overall financial performance until future periods. Q for risks related to the COVID - ​ (c) Income Taxes ​ Income taxes are accounted for in accordance with ASC 740, Income Taxes, using the asset and liability method. The Company’s provision for income taxes is based on the annual effective rate method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. ​ The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net-recorded amount, it would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. ​ (d) Recently Adopted Accounting Standards ​ In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , The Company adopted the new standard on July 1, 2019 using the modified retrospective method and the transition relief guidance provided by the FASB in ASU 2018 ​ Adoption of the new standard resulted in the Company recording operating lease ROU assets and operating lease liabilities of $52,083 and $83,852, respectively, as of July 1, 2019. The ROU assets were recorded net of $31,769 in deferred rent adjustments that were previously recorded in Accrued expenses and Deferred rent on the Consolidated Balance Sheets as of June 30, 2019. The adoption of this standard did not result in any cumulative-effect adjustments to Retained earnings. Additionally, there was no impact on the Company’s unaudited consolidated statements of operations and comprehensive income or the unaudited statement of cash flows as a result of the adoption of Topic 842 for the three and nine months ended March 31, 2019. ​ Refer to Note 8 for additional disclosures over the Company’s leases. ​ (e) Recently Issued Accounting Standards ​ In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which amends the requirements for fair value measurement disclosures. ASU 2018-13 removes, modifies or adds certain disclosure requirements under GAAP. This standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. Any new disclosure requirements must be applied on a prospective basis in the interim and annual periods of initial adoption; all removed or modified requirements must be applied retrospectively to all periods presented. The Company plans to adopt this standard on July 1, 2020 and does not expect any material impact from adoption. ​ In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”) which provides guidance to reduce complexity in certain areas of accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and simplifies various aspects of the current guidance to promote consistent application of the standard among reporting entities. This standard is effective for fiscal years beginning after December 15, 2020 with early adoption permitted. The Company is currently assessing the impact of ASU 2019-12 on its financial statements as well as the timing and method of adoption. ​ In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides optional practical expedients and exceptions for applying GAAP to contracts and transactions, including debt agreements, affected by interest rate reform as regulators discontinue the use of the London Interbank Offered Rate (LIBOR) and other similar reference rates. This standard is effective for contract modifications made as of March 12, 2020 through December 31, 2022, on a prospective basis. The Company adopted this standard upon its issuance, and it did not have a material impact on the Company’s financial statements. ​ From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of other recently issued standards that are not yet effective will not have a material impact on the Company’s consolidated financial statements upon adoption. ​

Revenue

Revenue	9 Months Ended
	Mar. 31, 2020
Revenue
Revenue	​ (3) Revenue ​ The Company derives its revenue from contracts predominantly from recurring and non-recurring service fees. While the majority of its agreements are generally cancellable by the client on 60 days’ notice or less, the Company also has term arrangements, which are generally two years in length. Recurring fees are derived from payroll, timekeeping, and HR-related cloud-based computing services. The majority of the Company’s recurring fees are satisfied over time as services are provided. The performance obligations related to payroll services are satisfied upon the processing of the client’s payroll with the fee charged and collected based on a per employee per payroll frequency fee. The performance obligations related to time and attendance services and HR related services are satisfied over time each month with the fee charged and collected based on a per employee per month fee. For subscription-based fees which can include payroll, time and attendance, and HR related services, the Company recognizes the applicable recurring fees over time each month with the fee charged and collected based on a per employee per month fee. Non-recurring service fees consist mainly of nonrefundable implementation fees, which involve setting the client up in, and loading data into, the Company’s cloud-based modules. These implementation activities are considered set-up activities. The Company has determined that the nonrefundable upfront fees provide certain clients with a material right to renew the contract. Implementation fees are deferred and amortized generally over a period up to 24 months. ​ Disaggregation of revenue ​ The following table disaggregates revenue by Recurring fees and Implementation services and other, which the Company believes depicts the nature, amount and timing of its revenue: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ March 31, ​ March 31, ​ 2019 2020 2019 2020 Recurring fees $ 129,976 $ 161,266 ​ $ 326,012 ​ $ 402,605 Implementation services and other 3,379 5,829 ​ 7,084 ​ 14,343 Total revenues from contracts $ 133,355 $ 167,095 ​ $ 333,096 ​ $ 416,948 ​ Deferred revenue ​ The timing of revenue recognition for recurring revenue is consistent with the timing of invoicing as they occur simultaneously based on the client’s payroll frequency or by month for subscription-based fees. As such, the Company does not recognize contract assets or liabilities related to recurring revenue. ​ The nonrefundable upfront fees related to implementation services are invoiced with the client’s first payroll period. The Company defers and recognizes these nonrefundable upfront fees generally over a period up to 24 months based on the type of contract. The following table summarizes the changes in deferred revenue (i.e. contract liability) related to these nonrefundable upfront fees as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ March 31, ​ March 31, ​ 2019 2020 2019 2020 Balance at beginning of the period ​ $ 3,623 ​ $ 6,853 ​ $ — ​ $ 6,289 Deferral of revenue ​ 4,730 ​ 6,099 ​ 10,243 ​ 12,342 Revenue recognized ​ ​ (2,354) ​ ​ (3,992) ​ ​ (4,244) ​ ​ (9,671) Balance at end of the period ​ $ 5,999 ​ $ 8,960 ​ $ 5,999 ​ $ 8,960 ​ Deferred revenue related to these nonrefundable upfront fees are recorded within Accrued expenses and Other long-term liabilities on the Unaudited Consolidated Balance Sheets. The Company expects to recognize these deferred revenue balances of $3,466 in fiscal 2020, $4,463 in fiscal 2021, $1,031 in fiscal 2022 and thereafter. ​ Deferred contract costs ​ The Company defers certain selling and commission costs that meet the capitalization criteria under ASC 340-40. The Company also capitalizes certain costs to fulfill a contract related to its proprietary products if they are identifiable, generate or enhance resources used to satisfy future performance obligations and are expected to be recovered under ASC 340-40. Implementation fees are treated as nonrefundable upfront fees and the related implementation costs are required to be capitalized and amortized over the expected period of benefit, which is the period in which the Company expects to recover the costs and enhance its ability to satisfy future performance obligations. ​ The Company utilizes the portfolio approach to account for both the cost of obtaining a contract and the cost of fulfilling a contract. These capitalized costs are amortized over the expected period of benefit, which has been determined to be over 7 years based on the Company’s average client life and other qualitative factors, including rate of technological changes.

Fair Value Measurement

Fair Value Measurement
Fair Value Measurement	(6) Fair Value Measurement ​ The Company applies the fair value measurement and disclosure provisions of ASC 820, Fair Value Measurements and Disclosures, and ASU 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: ​ ● Level 1—Quoted prices in active markets for identical assets and liabilities. ​ ● Level 2—Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. ​ ● Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. ​ The Company measures certain cash and cash equivalents, accounts receivable, accounts payable and client fund obligations at fair value on a recurring basis using Level 1 inputs. The Company considers the recorded value of these financial assets and liabilities to approximate the fair value of the respective assets and liabilities at June 30, 2019 and March 31, 2020 based upon the short-term nature of these assets and liabilities. ​ Marketable securities, consisting of securities classified as available-for-sale as well as certain cash equivalents, are recorded at fair value on a recurring basis using Level 2 inputs obtained from an independent pricing service. Available-for-sale securities include commercial paper, corporate bonds, asset-backed securities and U.S. treasury securities. The independent pricing service utilizes a variety of inputs including benchmark yields, broker/dealer quoted prices, reported trades, issuer spreads as well as other available market data. The Company, on a sample basis, validates the pricing from the independent pricing service against another third-party pricing source for reasonableness. The Company has not adjusted any prices obtained by the independent pricing service, as it believes they are appropriately valued. There were no available-for-sale securities classified in Level 3 of the fair value hierarchy at June 30, 2019 or March 31, 2020, and the Company did not transfer assets between Levels during the nine months ended March 31, 2019 or 2020. ​ The fair value level for the Company’s cash and cash equivalents and available-for-sale securities is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2019 ​ ​ Total ​ Level 1 Level 2 Level 3 Cash and cash equivalents ​ $ 132,476 ​ $ 116,387 ​ $ 16,089 ​ $ — Funds held for clients' cash and cash equivalents ​ ​ 1,293,667 ​ ​ 1,244,856 ​ ​ 48,811 ​ ​ — Available-for-sale securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial paper ​ ​ 63,428 ​ ​ — ​ ​ 63,428 ​ ​ — Corporate bonds ​ ​ 27,099 ​ ​ — ​ ​ 27,099 ​ ​ — Asset-backed securities ​ ​ 26,540 ​ ​ — ​ ​ 26,540 ​ ​ — U.S. treasury securities ​ ​ 13,757 ​ ​ — ​ ​ 13,757 ​ ​ — Total available-for-sale securities ​ ​ 130,824 ​ ​ — ​ ​ 130,824 ​ ​ — Total investments ​ $ 1,556,967 ​ $ 1,361,243 ​ $ 195,724 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2020 ​ ​ Total ​ Level 1 Level 2 Level 3 Cash and cash equivalents ​ $ 114,325 ​ $ 90,791 ​ $ 23,534 ​ $ — Funds held for clients' cash and cash equivalents ​ ​ 1,520,127 ​ ​ 1,439,324 ​ ​ 80,803 ​ ​ — Available-for-sale securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial paper ​ ​ 150,437 ​ ​ — ​ ​ 150,437 ​ ​ — Corporate bonds ​ ​ 52,248 ​ ​ — ​ ​ 52,248 ​ ​ — Asset-backed securities ​ ​ 57,586 ​ ​ — ​ ​ 57,586 ​ ​ — U.S. treasury securities ​ ​ 21,457 ​ ​ — ​ ​ 21,457 ​ ​ — Total available-for-sale securities ​ ​ 281,728 ​ ​ — ​ ​ 281,728 ​ ​ — Total investments ​ $ 1,916,180 ​ $ 1,530,115 ​ $ 386,065 ​ $ — ​

Debt
Debt	​ (7) Debt In July 2019, the Company entered into a five-year revolving credit agreement with PNC Bank, National Association, and other lenders, which is secured by substantially all of the Company’s assets, subject to certain restrictions. The revolving credit agreement provides for a senior secured revolving credit facility (the “credit facility”) under which the Company may borrow up to $250,000, which may be increased to up to $375,000, subject to obtaining additional lender commitments and certain approvals and satisfying other requirements. The credit facility is scheduled to mature in July 2024. As of March 31, 2020, no amounts have been drawn on the credit facility. In April 2020, the Company borrowed $100,000 under the credit facility. Refer to Note 13 for further details on the borrowing under the credit facility. The proceeds of any borrowings are to be used to fund working capital, capital expenditures and general corporate purposes, including permitted acquisitions, permitted investments, permitted distributions and share repurchases. The Company may generally borrow, prepay and reborrow under the credit facility and terminate or reduce the lenders’ commitments at any time prior to revolving credit facility expiration without a premium or a penalty, other than customary “breakage” costs with respect to London Interbank Offered Rate (“LIBOR”) revolving loans. Any borrowings under the credit facility will generally bear interest, at the Company’s option, at a rate per annum determined by reference to either the LIBOR (or a replacement index for the LIBOR rate) or an adjusted base rate, in each case plus an applicable margin ranging from 0.875% to 1.375% and 0.0% to 0.375%, respectively, based on the then-applicable net senior secured leverage ratio. Additionally, the Company is required to pay certain commitment, letter of credit fronting and letter of credit participation fees on available and/or undrawn portions of the credit facility. Under the credit facility, the Company is required to comply with certain customary affirmative and negative covenants, including a requirement to maintain a maximum net total leverage ratio of not greater than 4.00 to 1.00, a maximum net senior secured leverage ratio of not greater than 3.50 to 1.00 and a minimum interest coverage ratio of not less than 3.00 to 1.00. As of March 31, 2020, the Company was in compliance with all of the aforementioned covenants.

Leases
Leases	​ (8) Leases ​ The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating lease right-of-use assets, Accrued expenses, and Long-term operating lease liabilities in the Unaudited Consolidated Balance Sheets. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The operating lease right-of-use assets also include any lease payments made at or before the commencement date and are reduced by any lease incentives received. The Company’s lease terms may include options to extend or not terminate the lease when it is reasonably certain that it will exercise any such options. For the majority of its leases, the Company concluded that it is not reasonably certain that any renewal options would be exercised, and, therefore, the amounts are not recognized as part of Operating lease right-of-use assets nor Operating lease liabilities. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the expected lease term. The Company’s most significant leases are real estate leases of office space. The remaining operating leases are primarily comprised of leases of printers and other equipment. For all leases, the Company has elected the practical expedient permitted under Topic 842 to combine lease and non-lease components. As a result, non-lease components, such as common area or equipment maintenance charges, are accounted for as a single lease element. The Company does not have any finance leases. Fixed lease expense payments are recognized on a straight-line basis over the lease term. Variable lease payments vary because of changes in facts or circumstances occurring after the commencement date, other than the passage of time, and are often due to changes in an external market rate or the value of an index (e.g. Consumer Price Index). Certain of the Company’s operating lease agreements include variable payments that are passed through by the landlord, such as insurance, taxes, and common area maintenance, payments based on the usage of the asset, and rental payments adjusted periodically for inflation. Variable payments are expensed as incurred and included within variable rent expense. The Company’s lease agreements do not contain material residual value guarantees, restrictions, or covenants. ​ The components of operating lease expense were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ Nine Months Ended ​ ​ ​ March 31, 2020 ​ ​ March 31, 2020 ​ Operating lease cost ​ $ 2,358 ​ ​ $ 6,995 ​ Short-term lease cost ​ ​ 1 ​ ​ ​ 15 ​ Variable lease cost ​ ​ 848 ​ ​ ​ 2,308 ​ Total lease costs ​ $ 3,207 ​ ​ $ 9,318 ​ ​ The classification of the Company’s operating lease right-of-use assets and operating lease liabilities and other supplemental information related to the Company’s operating leases are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2020 ​ ​ Operating lease right-of-use assets ​ $ 50,180 ​ ​ Accrued expenses ​ $ 7,955 ​ ​ Long-term operating lease liabilities ​ $ 74,912 ​ ​ Weighted-average remaining lease term (years) ​ ​ 10.44 ​ ​ Weighted-average discount rate ​ ​ 3.83 % ​ ​ The following table summarizes supplemental cash flow information related to the Company’s operating leases as of March 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ ​ ​ March 31, 2020 ​ Cash paid for amounts included in the measurement of operating lease liabilities ​ $ 7,716 ​ Operating lease assets obtained in exchange for new liabilities ​ $ 2,723 ​ ​ The undiscounted cash flows for future maturities of the Company’s operating lease liabilities and the reconciliation to the balance of operating lease liabilities reflected on the Company’s balance sheet are as follows as of March 31, 2020: ​ ​ ​ ​ ​ ​ Remainder of fiscal 2020 ​ $ 2,755 ​ Fiscal 2021 ​ ​ 10,890 ​ Fiscal 2022 ​ ​ 9,609 ​ Fiscal 2023 ​ ​ 9,229 ​ Fiscal 2024 ​ ​ 9,210 ​ Thereafter ​ ​ 60,026 ​ Total undiscounted cash flows ​ ​ 101,719 ​ Less: Present value discount ​ ​ (18,852) ​ Total operating lease liabilities ​ $ 82,867 ​ ​ The table above excludes $546 in the undiscounted future minimum lease payments for operating lease liabilities that had not yet commenced for terms up to 5.67 years.

Benefit Plans
Benefit Plans	​ (9) Benefit Plans ​ (a) Equity Incentive Plan ​ The Company maintains a 2008 Equity Incentive Plan (the “2008 Plan”) and a 2014 Equity Incentive Plan (the “2014 Plan”) pursuant to which the Company has reserved shares of its common stock for issuance to its employees, directors and non-employee third parties. The 2014 Plan serves as the successor to the 2008 Plan and permits the granting of options to purchase common stock and other equity incentives at the discretion of the compensation committee of the Company’s board of directors. No new awards have been or will be issued under the 2008 Plan since the effective date of the 2014 Plan. Outstanding awards under the 2008 Plan continue to be subject to the terms and conditions of the 2008 Plan. The number of shares of common stock reserved for issuance under the 2014 Plan may increase each calendar year, continuing through and including January 1, 2024. The number of shares added each year may be equal to the lesser of (a) four and five tenths percent (4.5%) of the number of shares of common stock of the Company issued and outstanding on the immediately preceding December 31, or (b) an amount determined by the Company’s board of directors. The Company’s board of directors determined that it would not increase the number of shares in reserve for issuance under the 2014 Plan as of January 1, 2020 . ​ As of March 31, 2020, the Company had 12,518 shares allocated to the plans, of which 3,026 shares were subject to outstanding options or awards. Generally, the Company issues previously unissued shares for the exercise of stock options or vesting of awards; however, shares previously subject to 2014 Plan grants or awards that are forfeited or net settled at exercise or release may be reissued to satisfy future issuances. ​ The following table summarizes changes in the number of shares available for grant under the Company’s equity incentive plans during the nine months ended March 31, 2020: ​ ​ ​ ​ ​ ​ Number of Available for grant at July 1, 2019 ​ 9,759 ​ RSUs granted ​ (642) ​ Shares withheld in settlement of taxes and/or exercise price ​ 321 ​ Forfeitures ​ 93 ​ Shares removed ​ (39) ​ Available for grant at March 31, 2020 ​ 9,492 ​ ​ Shares removed represents forfeitures of shares and shares withheld in settlement of taxes and/or payment of exercise price related to grants made under the 2008 Plan. As noted above, no new awards will be issued under the 2008 Plan. ​ Stock-based compensation expense related to stock options, restricted stock units (“RSUs”), and the Employee Stock Purchase Plan (as described below) is included in the following line items in the accompanying unaudited consolidated statements of operations and comprehensive income: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ Nine Months Ended March 31, ​ ​ 2019 2020 2019 2020 Cost of revenues ​ $ 1,192 ​ $ 1,362 ​ $ 3,734 ​ $ 4,057 ​ Sales and marketing ​ 1,799 ​ 3,466 ​ 5,496 ​ 10,813 ​ Research and development ​ 1,287 ​ 1,899 ​ 4,025 ​ 4,945 ​ General and administrative ​ 5,035 ​ 2,789 ​ 15,582 ​ 14,533 ​ Total stock-based compensation expense ​ $ 9,313 ​ $ 9,516 ​ $ 28,837 ​ $ 34,348 ​ ​ In addition, the Company capitalized $659 and $535 of stock-based compensation expense in its capitalized internal-use software costs in the three months ended March 31, 2019 and 2020, respectively, and $1,980 and $1,843 in the nine months ended March 31, 2019 and 2020, respectively. ​ Under the 2008 and 2014 Plans, the exercise price of each option cannot be less than the fair value of a share of common stock on the grant date. The options vested ratably over a three ​ There were no stock options granted during the nine months ended March 31, 2019 or 2020.

As of March 31, 2020, the Company had recognized all stock-based compensation cost related to outstanding stock options and all outstanding options had vested. ​ The Company may also grant RSUs under the 2014 Plan with terms determined at the discretion of the compensation committee of the Company’s board of directors. RSUs generally vest over four years following the grant date. Certain RSU awards have time-based vesting conditions while other RSUs vest based on the achievement of certain revenue growth and Adjusted EBITDA margin targets in future fiscal years. For these performance-based RSUs, the Company recognizes stock-based compensation expense based upon the probable achievement of these aforementioned performance metrics. In the third quarter of fiscal 2020, the Company determined that the probable achievement of performance metrics for such outstanding performance-based awards would be lower as a result of the COVID-19 pandemic and its anticipated impact on the Company’s operating results. As a result, the Company reversed $2,053 in stock-based compensation expense associated with such awards during the three months ended March 31, 2020. ​ The following table represents restricted stock unit activity during the nine months ended March 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ Units Weighted RSU balance at July 1, 2019 ​ 1,813 ​ $ 53.78 ​ RSUs granted ​ 642 ​ $ 99.72 ​ RSUs vested ​ (708) ​ $ 49.75 ​ RSUs forfeited ​ (93) ​ $ 59.72 ​ RSU balance at March 31, 2020 ​ 1,654 ​ $ 73.57 ​ RSUs expected to vest at March 31, 2020 ​ 1,442 ​ $ 71.83 ​ ​ At March 31, 2020, there was $50,414 of total unrecognized compensation cost, net of estimated forfeitures, related to unvested restricted stock units granted. That cost is expected to be recognized over a weighted average period of 1.91 years. ​ (b) Employee Stock Purchase Plan ​ Under the Company’s Employee Stock Purchase Plan (“ESPP”), the Company can grant stock purchase rights to all eligible employees during specific offering periods not to exceed twenty-seven months. Each offering period will begin on the trading day closest to May 16 and November 16 of each year. Shares are purchased through employees’ payroll deductions, up to a maximum of 10% of employees’ compensation for each purchase period, at a purchase price equal to 85% of the lesser of the fair market value of the Company’s common stock at the first trading day of the applicable offering period or the purchase date. Participants may purchase up to $25 worth of common stock or 2 shares of common stock in any one year. The ESPP is considered compensatory and recorded as stock-based compensation expense. ​ As of March 31, 2020, a total of 950 shares of common stock were reserved for future issuances under the ESPP. The number of shares of common stock reserved for issuance under the ESPP may increase each calendar year, continuing through and including January 1, 2024. The number of shares added each year may be equal to the lesser of (a) 400, (b) seventy-five one hundredths percent (0.75%) of the number of shares of common stock of the Company issued and outstanding on the immediately preceding December 31, or (c) an amount determined by the Company’s board of directors. The Company’s board of directors determined that it would not increase the number of shares in reserve for issuance under the ESPP as of January 1, 2020 . ​ The Company issued 45 shares upon the completion of its six-month offering period ending November 15, 2019. The Company recorded compensation expense attributable to the ESPP of $516 and $831 for the three months ended March 31, 2019 and 2020, respectively, and $1,401 and $2,208 for the nine months ended March 31, 2019 and 2020, respectively, which is included in the summary of stock-based compensation expense above. The grant date fair value of the ESPP offering periods was estimated using the following weighted average assumptions: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ ​ ​ ​ March 31, ​ ​ ​ 2019 ​ ​ 2020 ​ Valuation assumptions: ​ ​ ​ ​ ​ ​ ​ Expected dividend yield ​ 0 % ​ 0 % ​ Expected volatility ​ 33.5 - 38.3 % ​ 38.6 - 43.3 % ​ Expected term (years) ​ 0.5 ​ ​ 0.5 ​ ​ Risk‑free interest rate ​ 2.10 - 2.48 % ​ 1.58 - 2.44 % ​ ​ (c) 401(k) Plan ​ The Company maintains a 401(k) plan with a matching provision that covers all eligible employees. The Company matches 50% of employees’ contributions up to 8% of their gross pay. Contributions were $1,604 and $2,176 for the three months ended March 31, 2019 and 2020, respectively, and $4,138 and $5,947 for the nine months ended March 31, 2019 and 2020, respectively.

Litigation	(10) Litigation ​ On July 12, 2019, a former employee filed a class and collective action complaint under federal and state law alleging that certain employees of the Company were misclassified as salaried exempt employees. The complaint seeks unpaid overtime and other damages. The Company has, without admitting any liability or wrongdoing, reached an agreement in principle to settle this matter. The settlement of this claim did not have a material impact to the Company’s financial position, results of operations, or liquidity. ​ From time to time, the Company is subject to litigation arising in the ordinary course of business. Many of these matters are covered in whole or in part by insurance. In the opinion of the Company’s management, the ultimate disposition of any matters currently outstanding or threatened will not have a material adverse effect on the Company’s financial position, results of operations, or liquidity. However, these matters are subject to inherent uncertainties and could materially impact the Company’s financial position, results of operations, or liquidity based on the final disposition of these matters.

Income Taxes	​ (11) Income Taxes ​ On March 27, 2020, the President signed the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) into law. While the Company continues to analyze the relevant provisions of the CARES Act, it does not expect the provisions of the legislation to have a significant impact on the Company’s income taxes. ​ The Company’s quarterly provision for income taxes is based on the annual effective rate method. The Company’s quarterly provision for income taxes also includes the tax impact of certain unusual or infrequently occurring items, if any, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, and other discrete items in the interim period in which they occur. ​ The Company’s effective tax rate was 23.7% and 16.7% for the three months ended March 31, 2019 and 2020, respectively. The Company’s effective tax rate for the three months ended March 31, 2019 was higher than the federal statutory rate of 21% primarily due to state income taxes and nondeductible expenses, partially offset by federal research and development credits. The Company’s effective tax rate for the three months ended March 31, 2020 was lower than the federal statutory rate of 21% primarily due to federal research and development credits, partially offset by an increase in valuation allowance. ​ The Company’s effective tax rate was 9.5% and 2.5% for the nine months ended March 31, 2019 and March 31, 2020, respectively. The Company’s effective tax rates for the nine months ended March 31, 2019 and March 31, 2020 were lower than the federal statutory rate of 21% primarily due to excess tax benefits from employee stock-based compensation and federal research and development credits.

Net Income Per Share	(12) Net Income Per Share ​ Basic net income per common share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares outstanding during the period and, if dilutive, potential common shares outstanding during the period. The Company’s potential common shares consist of the incremental common shares issuable upon the exercise of stock options, the release of restricted stock units, and the shares purchasable via the employee stock purchase plan as of the balance sheet date.

In April 2020, the Company borrowed $100,000 under this credit facility. Although the Company currently does not have any anticipated need for this additional liquidity, it utilized the borrowing capacity under the credit agreement to provide enhanced financial flexibility due to uncertain market conditions arising from the COVID-19 pandemic. As of March 31, 2020, the Company’s primary sources of liquidity were $114,325 of cash and cash equivalents and $72,679 of total corporate investments. ​ In April 2020, the Company acquired all of the shares outstanding of VidGrid, Inc. through a merger for purchase price consideration of $17,500, subject to customary escrow arrangements and purchase price adjustments. VidGrid, Inc. is a leading video platform provider that enables peer-to-peer video learning courses, transforming video into two-way communication. This transaction expands the Company’s product functionality around workplace video communication and reaffirms its commitment to stronger employee collaboration, engagement and retention while helping clients prepare for the workplaces of the future. The Company will account for the acquisition as a business combination in accordance with ASC 805: Business Combinations using the acquisition method of accounting and recognize assets and liabilities at fair value as of the date of acquisition. ​

Summary of Significant Accounting Policies
Basis of Presentation, Consolidation, and Use of Estimates	(a) Basis of Presentation, Consolidation and Use of Estimates ​ These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. ​ The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Future events and their effects cannot be predicted with certainty; accordingly, accounting estimates require the exercise of judgment. In March 2020, the World Health Organization declared the outbreak of the novel coronavirus disease (“COVID-19”) as a pandemic which ​ Beginning in fiscal 2020, the Company simplified the presentation of revenue and cost of revenues on its Unaudited Consolidated Statements of Operations and Comprehensive Income. The line items “Recurring fees” and “Implementation services and other” have been combined into one revenue line: “Recurring and other revenue”. Likewise, the line items “Cost of revenues – recurring revenues” and “Cost of revenues – implementation services and other” have been combined into one line: “Cost of revenues”. The Company changed the presentation of revenue and cost of revenues as Implementation services and other has become a smaller component of its overall revenue mix due to the human capital management (“HCM”) suite becoming a larger part of the portfolio. Previously reported results for the three and nine months ended March 31, 2019 have been reclassified to conform to the current presentation.
Interim Unaudited Consolidated Financial Information	(b) Interim Unaudited Consolidated Financial Information ​ The accompanying unaudited consolidated financial statements and notes have been prepared in accordance with GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the Company’s financial position, results of operations, changes in stockholders’ equity and cash flows. The results of operations for the three and nine months ended March 31, 2020 are not necessarily indicative of the results for the full year or the results for any future periods. The financial impacts from the COVID-19 pandemic became more observable in the latter half of March 2020. As a result, the impact of the COVID - 19 pandemic will not be fully known or reflected in the Company’s results of operations and overall financial performance until future periods. Q for risks related to the COVID -
Income Taxes	(c) Income Taxes ​ Income taxes are accounted for in accordance with ASC 740, Income Taxes, using the asset and liability method. The Company’s provision for income taxes is based on the annual effective rate method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. ​ The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net-recorded amount, it would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. ​
Recently Adopted Accounting Standards	(d) Recently Adopted Accounting Standards ​ In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , The Company adopted the new standard on July 1, 2019 using the modified retrospective method and the transition relief guidance provided by the FASB in ASU 2018 ​ Adoption of the new standard resulted in the Company recording operating lease ROU assets and operating lease liabilities of $52,083 and $83,852, respectively, as of July 1, 2019. The ROU assets were recorded net of $31,769 in deferred rent adjustments that were previously recorded in Accrued expenses and Deferred rent on the Consolidated Balance Sheets as of June 30, 2019. The adoption of this standard did not result in any cumulative-effect adjustments to Retained earnings. Additionally, there was no impact on the Company’s unaudited consolidated statements of operations and comprehensive income or the unaudited statement of cash flows as a result of the adoption of Topic 842 for the three and nine months ended March 31, 2019. ​ Refer to Note 8 for additional disclosures over the Company’s leases.
Recently Issued Accounting Standards	(e) Recently Issued Accounting Standards ​ In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which amends the requirements for fair value measurement disclosures. ASU 2018-13 removes, modifies or adds certain disclosure requirements under GAAP. This standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. Any new disclosure requirements must be applied on a prospective basis in the interim and annual periods of initial adoption; all removed or modified requirements must be applied retrospectively to all periods presented. The Company plans to adopt this standard on July 1, 2020 and does not expect any material impact from adoption. ​ In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”) which provides guidance to reduce complexity in certain areas of accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and simplifies various aspects of the current guidance to promote consistent application of the standard among reporting entities. This standard is effective for fiscal years beginning after December 15, 2020 with early adoption permitted. The Company is currently assessing the impact of ASU 2019-12 on its financial statements as well as the timing and method of adoption. ​ In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides optional practical expedients and exceptions for applying GAAP to contracts and transactions, including debt agreements, affected by interest rate reform as regulators discontinue the use of the London Interbank Offered Rate (LIBOR) and other similar reference rates. This standard is effective for contract modifications made as of March 12, 2020 through December 31, 2022, on a prospective basis. The Company adopted this standard upon its issuance, and it did not have a material impact on the Company’s financial statements. ​ From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of other recently issued standards that are not yet effective will not have a material impact on the Company’s consolidated financial statements upon adoption.
