Significant Accounting Policies	Note 2. Significant Accounting Policies Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, as well as those of our wholly owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnote disclosures required by GAAP for complete financial statements. The condensed consolidated financial statements reflect all adjustments considered necessary for a fair presentation of the consolidated results of operations and financial position for the interim periods presented. All such adjustments are of a normal recurring nature. The results of operations for the three and nine months ended June 30, 2021 are not necessarily indicative of the results to be expected for any other interim period or for the year ending September 30, 2021. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated and combined financial statements and notes contained in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. During the second quarter of fiscal 2021, we identified and corrected immaterial errors related to previously issued consolidated financial statements. In order to present the impact of the resulting adjustments, previously issued financial statements have been revised. See Note 16 – Impact on Previously Issued Financial Statements for Immaterial Adjustments for additional details, including a summary of the revisions to certain previously reported financial information presented herein for comparative purposes. Use of Estimates The financial statements are prepared in accordance with GAAP, which requires management to make estimates and assumptions. These estimates, judgments and assumptions can affect the reported amounts in the financial statements and the footnotes thereto. Actual results could differ materially from these estimates. On an ongoing basis, we evaluate our estimates, assumptions and judgments. Significant estimates inherent to the preparation of financial statements include: revenue recognition; allowance for credit losses; accounting for deferred costs; accounting for internally developed software; the valuation of goodwill and intangible assets; accounting for business combinations; accounting for stock-based compensation; accounting for income taxes; accounting for leases; accounting for convertible debt; and loss contingencies. We base our estimates on historical experience, market participant fair value considerations, projected future cash flows, and various other factors that are believed to be reasonable under the circumstances. Actual amounts could differ significantly from these estimates. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less. As of June 30, 2021, the estimated fair value of our money-market funds was $56.2 million. We estimated the fair value of our money-market funds from quoted prices for identical assets in active markets on the last trading day of the reporting period (Level 1). Concentration of Risk Financial instruments that potentially subject us to significant concentrations of credit risk primarily consist of trade accounts receivable. We perform ongoing credit evaluations of our customers’ financial condition and limit the amount of credit extended when deemed appropriate. Three customers accounted for 19.3%, 11.6%, and 10.3% of our Accounts receivable, net balance at June 30, 2021. Two customers accounted for 14.8% and 10.9% of our Accounts receivable, net balance at September 30, 2020. Derivative Financial Instruments We use derivative instruments, including forward contracts, to help manage foreign currency exposures. Derivative instruments are viewed as risk management tools by us and are not used for trading or speculative purposes. Derivatives that qualify for hedge accounting can be designated as either cash flow hedges, net investment hedges, or fair value hedges. We may enter into derivative contracts that economically hedge certain risks, even when hedge accounting does not apply, or we elect not to apply hedge accounting. Derivatives are recognized in the Condensed Consolidated Balance Sheet at fair value on a gross basis as either assets or liabilities and classified as current or noncurrent based upon whether the maturity of the instrument is less than or greater than 12 months. Changes in the fair value of derivatives not designated as hedges are reported in earnings primarily in Other income (expense), net. The cash flows associated with derivatives not designated as hedges are reported in cash flows from investing activities in the Condensed Consolidated Statement of Cash Flows. Recently Adopted Accounting Standards In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost, including trade receivables. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model that requires the use of forward-looking information to calculate credit loss estimates. This standard is effective for interim and annual reporting periods beginning after December 15, 2019. This standard is required to be adopted using the modified retrospective basis, with a cumulative-effect adjustment to Accumulated deficit as of the beginning of the first reporting period in which the guidance of this standard is effective. We adopted ASU 2016-13 using the modified retrospective approach as of October 1, 2020. The effects of applying ASU 2016-13 as a cumulative-effect adjustment to retained earnings was immaterial. Recently Issued Accounting Pronouncements to be Adopted In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, (“ASU 2020-04”). This update provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) contract modifications on financial reporting, caused by reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for debt with conversion options, revises the criteria for applying the derivatives scope exception for contracts in an entity’s own equity, and improves the consistency for the calculation of earnings per share. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2021, our fiscal year 2023. Early adoption is permitted for annual periods and interim periods within those annual periods beginning after December 15, 2020, our fiscal year 2022. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements.

Note 2. Significant Accounting Policies

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, as well as those of our wholly owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnote disclosures required by GAAP for complete financial statements.

The condensed consolidated financial statements reflect all adjustments considered necessary for a fair presentation of the consolidated results of operations and financial position for the interim periods presented. All such adjustments are of a normal recurring nature. The results of operations for the three and nine months ended June 30, 2021 are not necessarily indicative of the results to be expected for any other interim period or for the year ending September 30, 2021. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated and combined financial statements and notes contained in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

During the second quarter of fiscal 2021, we identified and corrected immaterial errors related to previously issued consolidated financial statements. In order to present the impact of the resulting adjustments, previously issued financial statements have been revised. See Note 16 – Impact on Previously Issued Financial Statements for Immaterial Adjustments for additional details, including a summary of the revisions to certain previously reported financial information presented herein for comparative purposes.

Use of Estimates

The financial statements are prepared in accordance with GAAP, which requires management to make estimates and assumptions. These estimates, judgments and assumptions can affect the reported amounts in the financial statements and the footnotes thereto. Actual results could differ materially from these estimates.

On an ongoing basis, we evaluate our estimates, assumptions and judgments. Significant estimates inherent to the preparation of financial statements include: revenue recognition; allowance for credit losses; accounting for deferred costs; accounting for internally developed software; the valuation of goodwill and intangible assets; accounting for business combinations; accounting for stock-based compensation; accounting for income taxes; accounting for leases; accounting for convertible debt; and loss contingencies. We base our estimates on historical experience, market participant fair value considerations, projected future cash flows, and various other factors that are believed to be reasonable under the circumstances. Actual amounts could differ significantly from these estimates.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less. As of June 30, 2021, the estimated fair value of our money-market funds was $56.2 million. We estimated the fair value of our money-market funds from quoted prices for identical assets in active markets on the last trading day of the reporting period (Level 1).

Concentration of Risk

Financial instruments that potentially subject us to significant concentrations of credit risk primarily consist of trade accounts receivable. We perform ongoing credit evaluations of our customers’ financial condition and limit the amount of credit extended when deemed appropriate. Three customers accounted for 19.3%, 11.6%, and 10.3% of our Accounts receivable, net balance at June 30, 2021. Two customers accounted for 14.8% and 10.9% of our Accounts receivable, net balance at September 30, 2020.

Derivative Financial Instruments

We use derivative instruments, including forward contracts, to help manage foreign currency exposures. Derivative instruments are viewed as risk management tools by us and are not used for trading or speculative purposes. Derivatives that qualify for hedge accounting can be designated as either cash flow hedges, net investment hedges, or fair value hedges. We may enter into derivative contracts that economically hedge certain risks, even when hedge accounting does not apply, or we elect not to apply hedge accounting.

Derivatives are recognized in the Condensed Consolidated Balance Sheet at fair value on a gross basis as either assets or liabilities and classified as current or noncurrent based upon whether the maturity of the instrument is less than or greater than 12 months.

Changes in the fair value of derivatives not designated as hedges are reported in earnings primarily in Other income (expense), net. The cash flows associated with derivatives not designated as hedges are reported in cash flows from investing activities in the Condensed Consolidated Statement of Cash Flows.

Recently Adopted Accounting Standards

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost, including trade receivables.

This standard is required to be adopted using the modified retrospective basis, with a cumulative-effect adjustment to Accumulated deficit as of the beginning of the first reporting period in which the guidance of this standard is effective.

We adopted ASU 2016-13 using the modified retrospective approach as of October 1, 2020. The effects of applying ASU 2016-13 as a cumulative-effect adjustment to retained earnings was immaterial.

Recently Issued Accounting Pronouncements to be Adopted

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, (“ASU 2020-04”). This update provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) contract modifications on financial reporting, caused by reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements.

In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for debt with conversion options, revises the criteria for applying the derivatives scope exception for contracts in an entity’s own equity, and improves the consistency for the calculation of earnings per share. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2021, our fiscal year 2023. Early adoption is permitted for annual periods and interim periods within those annual periods beginning after December 15, 2020, our fiscal year 2022. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements.
