Adoption of new accounting standards
In March 2020, the SEC amended Rule 3-10 of Regulation S-X regarding financial disclosure requirements for registered debt offerings involving subsidiaries as either issuers or guarantors. This amended rule narrows the circumstances that require separate financial statements or summarized financial disclosures of subsidiary issuers and guarantors and simplifies the summarized disclosures required in lieu of those statements. As a result of this amended rule, we have included narrative disclosures in lieu of separate financial statements and summarized financial disclosures as amounts presented would not be material because the guarantor and subsidiary issuer do not have material independent assets and operations unrelated to investments in consolidated subsidiaries.
