Summary Of Significant Accounting Policies Summary of Significant Accounting Policies

The significant accounting policies used in preparation of these condensed consolidated financial statements for the three months ended March 29, 2020 are consistent with those discussed in Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2019, except as updated below with respect to newly adopted accounting standards.

The preparation of these financial statements in conformity with GAAP requires management to make estimates and
assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying disclosures.
Some of the more significant estimates, which are impacted by management's estimates and assumptions regarding the effects of COVID-19, relate to recoverability of goodwill and indefinite-lived trade names, estimated total costs for ongoing long-term contracts accounted for as performance obligations where transfer of control occurs over time, inventory valuation, share-based compensation, amortization and impairment of long-lived assets, income taxes, penalty accruals for late shipments, other asset valuations, and product warranties. While management believes that the estimates and assumptions used in the preparation of the financial statements are appropriate, actual future results as estimated in the current period could differ materially from those estimates.

New Accounting Standards
In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments. The new guidance, referred to as the current expected credit loss (“CECL”) model, requires the measurement of expected credit losses for financial assets (e.g., accounts receivable) held at the reporting date based on historical experience, current economic conditions, and reasonable and supportable forecasts which generally result in the more timely recognition of losses. The adoption of this new guidance on January 1, 2020 did not have a material impact on our condensed consolidated financial statements.
