In our opinion, all adjustments, which include only normal recurring adjustments necessary to fairly present the financial position, results of operations, changes in stockholders’ equity, and cash flows at January 31, 2021 and for the periods presented, have been included. All intercompany transactions have been eliminated in consolidation. The consolidated balance sheet as of April 30, 2020 has been derived from our audited consolidated financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, or GAAP, have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended April 30, 2020. The results of operations for the three and nine months ended January 31, 2021 may not be indicative of the results that may be expected for the fiscal year ending April 30, 2021, or any other period. Recently Issued Accounting Standards – In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update, or ASU, 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, or ASU 2016-13. ASU 2016-13 changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments, including trade receivables, from an incurred loss model to an expected loss model and adds certain new required disclosures. Under the expected loss model, entities will recognize credit losses to be incurred over the entire contractual term of the instrument rather than delaying recognition of credit losses until it is probable the loss has been incurred. The requirements of ASU 2016-13 are effective for financial statements for annual periods beginning after December 15, 2019, and early adoption is permitted. We adopted ASU 2016-13 on May 1, 2020, and the adoption of ASU 2016-13 did not have a material impact on our condensed consolidated financial statements.
