Variable Interest Entities

We evaluate our ownership, contractual, and other interests in entities to determine if they are a variable interest entity (“VIE”), if we have a variable interest in those entities, and the nature and extent of those interests. These evaluations may involve management judgment and the use of estimates and assumptions based on available historical information, among other factors. Based on our evaluations, if we determine we are the primary beneficiary of such VIEs, we consolidate such entities into our financial statements.

Consolidated Variable Interest Entities

We consolidate a VIE when we have the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits of the VIE and, as a result, are considered the primary beneficiary of the VIE.

On January 1, 2020, GI Alliance ("GIA") entered into a management services arrangement with Texas Digestive Disease Consultants, PLLC (“TDDC”) that authorized GIA to perform certain management services in the manner that it deemed reasonably appropriate to meet the day-to-day business needs of TDDC. In exchange for the management services provided, GIA is entitled to receive an annual management fee equal to a percentage of TDDC’s net operating income. The agreement has a 15 year term with two successive 5 year terms set to renew automatically. Based on these determinations, we concluded that TDDC is a VIE and that GIA is the primary beneficiary.

The VIE does not have a material impact on our condensed consolidated statements of earnings or condensed consolidated statements of cash flows. Total assets and liabilities included in the consolidated balance sheets for the VIE were $524 million and $249 million, respectively, as of March 31, 2025.
