Basis of Presentation and New Accounting Standards	Basis of Presentation and New Accounting Standards Overview Cree, Inc. (the Company) is an innovator of wide bandgap semiconductors, focused on silicon carbide and gallium nitride (GaN) materials and devices for power and radio-frequency (RF) applications. The Company's silicon carbide and GaN materials and devices are targeted for applications such as transportation, power supplies, inverters and wireless systems. In addition, the Company is an innovator of specialty lighting-class light emitting diode (LED) products. The Company's LEDs are targeted for use in indoor and outdoor lighting, electronic signs and signals and video displays. As discussed more fully below in Note 2, “Discontinued Operations,” on October 18, 2020, the Company entered into a definitive agreement to sell certain assets and subsidiaries comprising its former LED Products segment (the LED Business) to SMART Global Holdings, Inc. (SGH) and its wholly owned newly-created acquisition subsidiary (collectively with SGH, SMART) for up to $300 million, including fixed upfront and deferred payments and contingent consideration (the LED Business Divestiture). As a result, the Company has classified the results and cash flows of the LED Products segment as discontinued operations in its consolidated statements of operations and consolidated statements of cash flows for all periods presented. Additionally, the related assets and liabilities associated with the discontinued operations are classified as held for sale in the consolidated balance sheets. Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to the Company's continuing operations. The Company’s continuing operations consist of the Wolfspeed business, which includes silicon carbide and GaN materials, power devices and RF devices based on wide bandgap semiconductor materials and silicon. The Company’s materials products and power devices are used in electric vehicles, motor drives, power supplies, solar and transportation applications. The Company’s materials products and RF devices are used in military communications, radar, satellite and telecommunication applications. The majority of the Company's products are manufactured at its production facilities located in North Carolina, California, Arkansas and China. The Company also uses contract manufacturers for certain products and aspects of product fabrication, assembly and packaging. Additionally, the Company is in the process of building a silicon carbide fabrication facility in New York. The Company operates research and development facilities in North Carolina, Arizona, Arkansas, New York, California and China (including Hong Kong). Cree, Inc. is a North Carolina corporation established in 1987, and its headquarters are in Durham, North Carolina. Basis of Presentation The consolidated financial statements presented herein have been prepared by the Company and have not been audited. In the opinion of management, all normal and recurring adjustments necessary to fairly state the consolidated financial position, results of operations, comprehensive loss, shareholders' equity and cash flows at December 27, 2020, and for all periods presented, have been made. All material intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 28, 2020 has been derived from the audited financial statements as of that date. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 28, 2020 (fiscal 2020). The results of operations for the three and six months ended December 27, 2020 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 27, 2021 (fiscal 2021). Additionally, the impact of the COVID-19 pandemic to the results of operations is uncertain. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates. The Company revised income tax expense for the three and six months ended December 29, 2019 to correct the income tax provision calculation for the second quarter of fiscal 2020. The Company increased income tax expense for the three and six months ended December 29, 2019, resulting in a net increase to net loss of $1.5 million in each period. The Company will also revise the unaudited statements of operations for the three months ended March 29, 2020 in the unaudited interim consolidated financial statements to be filed in the Quarterly Report on Form 10-Q for the corresponding period in fiscal 2021 to decrease income tax expense by $1.5 million for the three months ended March 29, 2020, which will result in a net decrease to net loss of $1.5 million for the three months ended March 29, 2020. No revision will be required to the unaudited statement of operations for the nine months ended March 29, 2020 in the unaudited interim consolidated financial statements to be filed in the Quarterly Report on Form 10-Q for the corresponding period in fiscal 2021. The Company concluded these errors were not material individually or in the aggregate to any of the periods impacted. Certain accounting matters that generally require consideration of forecasted financial information were assessed regarding impacts from the COVID-19 outbreak as of December 27, 2020 and through the date of this Quarterly Report using reasonably available information as of those dates. The accounting matters assessed included, but were not limited to, allowance for doubtful accounts, the carrying value of goodwill and other long-lived tangible and intangible assets, the potential impact to earnings of unrealized losses on investments, valuation allowances for tax assets and the ability to estimate an annual effective tax rate. While the assessments resulted in no material impacts to the consolidated financial statements as of and for the quarter ended December 27, 2020, the Company believes the full impact of the outbreak remains uncertain and will continue to assess if ongoing developments related to the outbreak may cause future material impacts to its consolidated financial statements. Segment Reporting As a result of the pending LED Business Divestiture, the Company has determined that it operates a single reporting segment within continuing operations, Wolfspeed. Accordingly, the Chief Operating Decision Maker (CODM) allocates resources and assesses performance on a consolidated basis. The Company's identified CODM is the Chief Executive Officer. Recently Adopted Accounting Pronouncements Credit Losses In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). This standard replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. The Company adopted this standard using the modified retrospective transition method on June 29, 2020, the first day of its 2021 fiscal year. Upon adoption, prior period balances were not adjusted and the Company determined no cumulative-effect adjustment to retained earnings as of June 29, 2020 was required. Under this new standard, expected credit losses for the Company's receivables are evaluated on a collective (pool) basis and aggregated on the basis of similar risk characteristics. These aggregated risk pools are reassessed at each measurement date. A combination of factors is considered in determining the appropriate estimate of expected credit losses, including broad-based economic indicators as well as customers' financial strength, credit standing, payment history and any historical defaults. Available-for-sale debt securities in an unrealized loss position at each measurement date are individually evaluated for expected credit losses. The Company evaluates whether the unrealized loss is due to market factors or changes in the investment holdings' credit rating. An expected credit loss will be recorded when an investment in an unrealized loss position is determined to have lost value from a decreased credit rating and the Company does not expect to recover the fair value of the security. Accounting Pronouncements Pending Adoption Convertible Debt Instruments In August 2020, the FASB issued ASU 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). This standard simplifies the accounting for convertible instruments by eliminating the cash conversion and the beneficial conversion accounting models. This update also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity. The update requires an entity to use the if-converted method for all convertible instruments in the diluted earnings per share calculation. An entity may use either a modified or full retrospective approach for adoption. The Company expects to adopt this standard by June 27, 2022 and is currently evaluating the impact on its consolidated financial statements.
