The Predecessor is evaluating the impact, if any, that the adoption of this update will have on the Predecessor’s condensed consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires all leasing arrangements to be presented in the balance sheet as liabilities along with a corresponding asset.
