Effective June 30, 2019, we adopted Topic 842, using the modified retrospective transition approach. We applied the new guidance to all leases existing as of the date of adoption. Our reported results beginning with the first quarter of fiscal 2020 reflect the application of Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our historical accounting under Topic 840.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:24px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">We elected the practical expedient package permitted under the transition approach. As such, we did not reassess whether any expired or existing contracts are or contain leases, we did not reassess our historical lease classification, and we did not reassess our initial direct costs for any leases that existed prior to June 30, 2019. We have also elected to combine lease and non-lease components at a portfolio level for our operating leases of buildings and not to report leases with an initial term of 12 months or less on our balance sheet.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:24px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As of the date of adoption, we recognized operating lease assets of </span><span style="font-family:inherit;font-size:10pt;"><span>$91.5 million</span></span><span style="font-family:inherit;font-size:10pt;">, with corresponding operating lease liabilities of </span><span style="font-family:inherit;font-size:10pt;"><span>$81.5 million</span></span><span style="font-family:inherit;font-size:10pt;"> on the consolidated balance sheets. The difference between the operating lease right-of-use assets and operating lease liabilities primarily represents the existing asset recognized in relation to the favorable terms of an operating lease acquired through a business combination offset by our deferred rent and ASC 420 “cease-use” balances. </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:24px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">All existing leases that were classified as capital leases under Topic 840 are classified as finance leases under the new guidance. As of adoption, we recognized finance lease assets of </span><span style="font-family:inherit;font-size:10pt;"><span>$12.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> in property, plant and equipment, net, with corresponding finance lease liabilities of </span><span style="font-family:inherit;font-size:10pt;"><span>$12.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> on the consolidated balance sheets.

The guidance also requires certain new disclosures regardless of the election. The amendments in ASU 2018-02 are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. We adopted ASU 2018-02 in the first quarter of fiscal 2020 with no impact to our consolidated financial statements.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:24px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In January 2017, FASB issued ASU 2017-04, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment</span><span style="font-family:inherit;font-size:10pt;">. ASU 2017-04 removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment charge will be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The amendments contained in ASU 2017-04 are effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted, which should be applied prospectively.

As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost. These changes will reduce reported interest expense and increase reported net income for entities that have issued a convertible instrument that </span><span style="font-family:inherit;font-size:10pt;">was bifurcated according to previously existing rules</span><span style="font-family:inherit;font-size:10pt;">. Also, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will be no longer available.

The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. ASU 2018-13 requires that certain of the amendments be applied prospectively, while other amendments should be applied retrospectively to all periods presented.
