The unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (“SEC”) Guidelines, Rules and Regulations and, in the opinion of management, reflect all normal recurring adjustments necessary for a fair presentation of results for the unaudited interim periods presented. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted. The results of operations for the interim period are not necessarily indicative of the results to be obtained for the full fiscal year. All intercompany accounts and transactions have been eliminated upon consolidation in the unaudited consolidated financial statements.

We recognize revenue at an amount that reflects the consideration we expect to be entitled to in exchange for transferring goods or services to a customer, in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). See Note 3, Revenue Recognition, for additional information.

We measure stock-based compensation cost based on the estimated fair value of the award on the grant date and recognize the expense over the requisite service period, typically on a straight-line basis. We recognize stock-based compensation expense for awards with performance conditions if and when we conclude that it is probable that the performance conditions will be achieved. The fair value of equity awards is recognized as expense in the same period and in the same manner as if we had paid cash for the goods or services. Forfeitures are recognized as they occur. We issue new shares of common stock upon vesting of equity awards and upon exercise of vested options. We do not intend to repurchase any issued shares of common stock. During the three months ended September 30, 2021 and 2020 we recognized $23,745 and $14,331 of equity compensation expense, respectively. During the six months ended September 30, 2021 and 2020 we recognized $49,911 and $23,914 of equity compensation expense, respectively. At September 30, 2021, aggregate unrecognized compensation expense related to outstanding awards was $233,469.

Upon closing of the UHG Transaction, existing awards will generally convert to equivalent UHG awards with consistent vesting provisions. Certain awards will vest upon closing of the UHG Transaction per the terms of the UHG Agreement.

In March 2020, the FASB issued ASU No. 2020-04, as amended by ASU No. 2021-01, which created Topic 848 – Reference Rate Reform. ASU No. 2020-04 contains optional practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts which may be elected over time as activities occur. Among other things, the ASU intends to ease the transition from LIBOR to an alternative reference rate. During the first quarter of fiscal year 2021, we elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. We continue to evaluate the impacts of ASU No. 2020-04 and may apply other elections as reference rate reform activities progress.

In August 2020, the FASB issued ASU No. 2020-06 which simplifies the accounting for convertible instruments and amends the guidance addressing the derivatives scope exception for contracts in an entity’s own equity. The standard is scheduled to be effective for us beginning April 1, 2022. Given the forward purchase contracts of our Tangible Equity Units (“TEUs”) qualify for the derivatives scope exception and are currently accounted for under that guidance, we do not expect a material impact upon adoption. We will continue to evaluate the impact of this pronouncement prior to adoption.
