The adoption of this guidance is expected to materially increase assets and liabilities on the consolidated balance sheets. The Company does not expect the adoption of this guidance to have a material impact on its existing debt covenants. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 provides financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. This guidance is effective for the Company on April 1, 2020. The Company is evaluating the effect that adoption of this guidance will have on its consolidated financial statements and related disclosures.
