2. Summary of Significant Accounting Policies and New Accounting Standards

Our significant accounting policies are described in the notes to the consolidated financial statements included in our Annual Report. We adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), effective July 1, 2019. See “New Accounting Standards” and “Note 7—Leases.” As of March 31, 2020, there have been no other material changes to our significant accounting policies.

Leases

We determine at the inception of an arrangement whether the arrangement contains a lease. If an arrangement contains a lease, we assess the lease term when the underlying asset is available for use (“lease commencement”). Individual lease terms reflect the non-cancellable period of the lease, reasonably certain renewal periods and consideration of termination options. We determine the lease classification as either operating or financing at lease commencement, which governs the pattern of expense recognition and presentation in our consolidated financial statements. Our current lease portfolio only includes operating leases.

We recognize a right-of-use (“ROU”) asset and a corresponding lease liability at lease commencement for leases with terms exceeding twelve months. Short-term leases with terms of twelve months or less are not recognized on the consolidated balance sheet and lease payments are recognized on a straight-line basis over the term.

The values of the ROU assets and lease liabilities are calculated based on the present value of the fixed payment obligations over the lease term, using our incremental borrowing rate (“IBR”), determined at lease commencement. The IBR reflects the rate of interest we would expect to pay on a secured basis to borrow an amount equal to the lease payments under similar terms. The IBR incorporates the term and economic environment of the respective lease arrangements.

We have elected to account for lease and non-lease components together as a single lease component and include fixed payment obligations related to such non-lease components in the measurement of ROU assets and lease liabilities. Fixed lease payments are recognized on a straight-line basis over the lease term. Variable lease payments can include index-based lease payments, real estate taxes, maintenance costs, utilization charges and other non-lease services paid to lessors and are not determinable at lease commencement. Variable lease payments are not included in the measurement of ROU assets and lease liabilities and are recognized in the period incurred.

Net Income per Share and Weighted Average Shares

Basic net income per share is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period.

Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period after giving effect to potential dilutive common shares resulting from the assumed exercise of stock options and vesting of restricted stock units. All common share equivalents were included in the calculation of diluted net income per share in the periods included in the consolidated financial statements.

New Accounting Standards

ASU 2020-04, Reference Rate Reform (Topic 848), provides optional expedients and exceptions to GAAP guidance for contracts and hedging relationships that reference the London Interbank Offered Rate (LIBOR) and other interbank offered rates expected to be discontinued by rate reform. The purpose of this guidance is to ease the financial reporting burdens related to the expected market transition to alternative reference rates. This ASU may be applied beginning with the interim period ended March 31, 2020, and prospectively through December 31, 2022. We are currently evaluating the effect of adoption of this guidance on our consolidated financial statements.

ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, removes certain exceptions and amends certain requirements in the existing income tax guidance to ease accounting requirements. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, and must be applied on a retrospective basis. We continue to evaluate the effect of adoption of this guidance on our consolidated financial statements.

ASU 2018‑14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715‑20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans, modifies existing disclosure requirements for defined benefit pension and other postretirement plans. This ASU is effective for fiscal years ending after December 15, 2020, and must be applied on a retrospective basis. We continue to evaluate the effect of adoption of this guidance on our consolidated financial statements.

ASU 2018‑13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, modifies existing disclosure requirements for fair value measurement. This ASU is effective for fiscal years beginning after December 15, 2019. We continue to evaluate the effect of adoption of this guidance on our consolidated financial statements.

ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, allows reclassification from accumulated other comprehensive income to retained earnings of stranded tax effects related to adjustments resulting from the United States Tax Cuts and Jobs Act. This ASU is effective for our consolidated financial statements beginning July 1, 2019. The adoption of this guidance did not have a material effect on our consolidated financial statements.

ASU 2016-02, Leases (Topic 842), requires an entity to recognize assets and liabilities on the balance sheet for both financing and operating leases and requires additional qualitative and quantitative disclosures regarding leasing arrangements. We adopted ASU 2016-02 and its amendments effective July 1, 2019, using a modified retrospective transition approach, which does not require modifications to periods prior to the date of initial application. We utilized certain permitted practical expedients intended to ease transition to the new standard, including carrying forward the original lease classifications without reassessment. We did not use hindsight in our assessment of lease terms as of the effective date. Upon adoption of ASU 2016-02 on July 1, 2019, we recognized initial ROU assets and lease liabilities of $18,576 and $19,368 respectively, on the consolidated balance sheet. The difference in the amounts of the ROU assets and lease liabilities recognized relates to landlord incentives and deferred rent. An adjustment to opening retained earnings was not required, and the recognition of lease expense in the consolidated statements of operations did not change significantly.
