Financial Statement Preparation. These condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and the instructions to Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the interim financial information includes all normal recurring adjustments necessary for a fair statement of the results for the interim periods. These condensed consolidated financial statements are unaudited and should be read in conjunction with our Annual Report on Form 10-K for our fiscal year ended September 27, 2020. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year. We operate and report using a 52-53 week fiscal year ending on the last Sunday in September. Each of the three months ended December 27, 2020 and December 29, 2019 included 13 weeks.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our condensed consolidated financial statements and the accompanying notes. Actual results could differ from those estimates. Certain prior year amounts have been reclassified to conform to the current year presentation.
Recently Adopted Accounting Guidance.
Financial Assets: In June 2016, the Financial Accounting Standards Board (FASB) issued new accounting guidance that changes the accounting for recognizing impairments of financial assets. Under the new accounting guidance, credit losses for financial assets held at amortized cost (such as accounts receivable) are estimated based on expected losses rather than the previous incurred loss impairment model. The new accounting guidance also eliminated the concept of other-than-temporary impairment with credit losses related to available-for-sale debt securities recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. We adopted the new accounting guidance in the first quarter of fiscal 2021 under the modified retrospective transition method, except for certain available-for-sale debt securities where the prospective transition method was required, and as a result, prior period results have not been restated. The impact upon adoption was not material to our condensed consolidated financial statements. The future impact of such accounting guidance will largely depend on the future composition and credit quality of our investment portfolio and accounts receivable, as well as future economic conditions.
Accounting Policy Update.
Marketable Securities: As a result of the adoption of the new accounting guidance described above, we revised our accounting policy beginning in fiscal 2021 as follows.
Marketable securities include marketable equity securities, available-for-sale debt securities and, from time-to-time, certain time deposits. We classify marketable securities as current or noncurrent based on the nature of the securities and their availability for use in current operations. Marketable securities are stated at fair value with all realized and unrealized gains and losses on investments in marketable equity securities and realized gains and losses on available-for-sale debt securities recognized in investment and other income, net. Debt securities are classified as available for sale or held to maturity at the time of purchase and reevaluated at each balance sheet date. The realized and unrealized gains and losses on marketable securities are determined using the specific identification method.
If a debt security has an unrealized loss and we either intend to sell the security or it is more likely than not that we will be required to sell the security before its anticipated recovery, we record an impairment charge to investment and other income, net for the entire amount of the unrealized loss and adjust the amortized cost basis of the security. For the remaining debt securities, if an unrealized loss exists, we separate the impairment into the portion of the loss related to credit factors and the portion of the loss that is not related to credit factors. Unrealized gains or unrealized losses that are not related to credit factors on available-for-sale debt securities are recorded as a component of accumulated other comprehensive income, net of income taxes. Unrealized losses that are related to credit loss factors on available-for-sale debt securities and subsequent adjustments to the credit loss are recorded as an allowance for credit losses, which is included in investment and other income, net. In evaluating whether a credit loss exists, we consider a variety of factors, including the significance of the decline in value as compared to the cost basis; underlying factors contributing to a decline in the prices of securities in a single asset class; the security’s relative performance versus its peers, sector or asset class; the market and economy in general; views of external investment managers; news or financial information that has been released specific to the investee; and the outlook for the overall industry in which the investee operates.
