Recent Accounting Pronouncements	2. Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (the “FASB”) issued updated guidance which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The Company adopted this standard on September 1, 2019 using the modified retrospective adoption method. The standard provides a number of optional practical expedients in transition and the Company has elected certain of these practical expedients upon adoption of this standard. Specifically, the Company elected the package of practical expedients permitted under the standard, which allows a lessee to carry forward its population of existing leases, the classification of each lease, as well as the treatment of initial direct lease costs as of the period of adoption. The Company also elected the practical expedient related to lease and non-lease components, as an accounting policy election which allows a lessee to not separate non-lease from lease components and instead account for consideration paid in a contract as a single lease component. In addition, the Company elected the short-term lease recognition exemption for all leases with a term of 12 months or less, which means it will not recognize right-of-use assets or lease liabilities for these leases. The adoption of this standard resulted in the Company recognizing right-of-use assets, net of $48.7 million and corresponding lease liabilities of $46.2 million and reductions of prepaid expenses and other current assets of $1.2 million and $1.3 million, respectively. The adoption of this standard did not have a material impact on the Company's consolidated statement of income or consolidated statement of cash flows. In June 2016, the FASB issued updated guidance that introduces a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments including trade receivables. The estimate of expected credit losses will require entities to incorporate historical information, current information and reasonable and supportable forecasts. This guidance also expands the disclosure requirements to enable users of financial statements to understand the entity’s assumptions, models and methods for estimating expected credit losses. This guidance is effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2019 with early adoption permitted. Accordingly, the guidance will be effective for the Company on August 30, 2020. The Company is currently evaluating the impact that this guidance will have on its financial statements and related disclosures. In August 2018, the FASB issued updated guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This guidance will be effective for annual reporting periods, and any interim periods within those annual periods, ending after December 15, 2020 and will be required to be applied on a retrospective basis with early adoption permitted. Accordingly, the standard will be effective for the Company on August 29, 2021. The Company is currently evaluating the impact that this guidance will have on its financial statements and related disclosures. In August 2018, the FASB issued guidance that addresses customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract and also adds certain disclosure requirements related to implementation costs incurred for internal-use software and cloud computing arrangements. This guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This guidance is effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2019 with early adoption permitted. The amendments in this update can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Accordingly, the guidance will be effective for the Company on August 30, 2020. The Company is currently evaluating the impact that this guidance will have on its financial statements and related disclosures. In December 2019, the FASB issued updated guidance to simplify accounting for income taxes by removing certain exceptions and improving the consistent application of and simplifying U.S. GAAP in other areas of this topic. This guidance is effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2020 with early adoption permitted.
