New Accounting Pronouncement or Change in Accounting Principle, Description	In February 2016, the Financial Accounting Standards Board(the “FASB”) issued ASU 2016-02, Leases (Topic 842). Lessees are required to recognize a right-of-use asset and alease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The liabilityis equal to the present value of lease payments. The asset is based on the liability, subject to certain adjustments, such asfor initial direct costs. For income statement purposes, a dual model was retained, requiring leases to be classified as eitheroperating or finance leases. Operating leases result in straight-line expense (similar to operating leases under the prior accountingstandard) while finance leases result in a frontloaded expense pattern (similar to capital leases under the prior accounting standard).The Company adopted this new accounting standard on February3, 2019 on a modified retrospective basis and applied the new standard to all leases greater than one year. As a result, comparativefinancial information has not been restated and continues to be reported under the accounting standards in effect for those periods.The Company elected the package of practical expedients permitted under the transition guidance within the new standard, whichincludes, among other things, the ability to carry forward the existing lease classification. The Company does not engage in anyLessor transactions, and as a Lessee, the Company does not have any finance leases. As a result, the new standard had a materialimpact on the unaudited condensed consolidated balance sheet, but did not materially impact the Company’s consolidated operatingresults and did not materially impact the Company’s cash flows.
