Leases

In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-01, Leases (Topic 842): Common Control Arrangements, which requires companies to amortize leasehold improvements associated with related party leases under common control over the useful life of the leasehold improvement to the common control group. The ASU is effective for annual reporting periods beginning on or after December 15, 2023; however, early adoption is permitted. The ASU can either be applied prospectively or retrospectively.

The Company adopted this ASU using the prospective method of transition on January 1, 2024. There was not a material impact on the Company’s consolidated financial statements upon adoption.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates.

Credit Risk Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash balances and accounts receivable. The Company’s excess cash is held with large financial institutions. The Company grants unsecured credit to its patients, most of whom reside in the service area of the Company’s facilities and are insured under third-party payor agreements.

Because of the diversity in the Company’s non-governmental third-party payor base, as well as their geographic dispersion, accounts receivable due from the Medicare program represent the Company’s only significant concentration of credit risk.

Redeemable Non-Controlling Interests

The ownership interests held by outside parties in subsidiaries, which include limited liability companies and limited partnerships, controlled by the Company are classified as non-controlling interests. Some of the Company’s non-controlling ownership interests consist of outside parties that have certain redemption rights that, if exercised, require the Company to purchase the parties’ ownership interests. These interests are classified and reported as redeemable non-controlling interests and have been adjusted to their redemption values, after the attribution of net income or loss.

Variable Interest Entities

Certain states prohibit the “corporate practice of medicine,” which restricts the Company from owning medical practices which directly employ physicians or therapists and from exercising control over medical decisions by physicians and therapists. In these states, the Company enters into long-term management agreements with medical practices that are owned by licensed physicians or therapists, which, in turn, employ or contract with physicians or therapists who provide professional medical services. The management agreements provide for the Company to direct the transfer of ownership of the medical practices. Based on the provisions of the management agreements, the medical practices are variable interest entities for which the Company is the primary beneficiary.
