The sale of 80% of the Company's equity in its Health Care Services segment on July 1, 2021 reduced its revenue from government reimbursement programs. Government reimbursements represented 18.0%, 18.8%, and 18.5% of resident fee revenue for the CCRCs segment for the years ended December 31, 2022, 2021, and 2020, respectively. Refer to Note 21 for disaggregation of revenue by reportable segment.

The payment terms and conditions within the Company's revenue-generating contracts vary by contract type and payor source, although terms generally include payment to be made within 30 days. Resident fee revenue for recurring and routine monthly services is generally billed monthly in advance under the Company's independent living, assisted living, and memory care residency agreements. Resident fee revenue for standalone or certain healthcare services is generally billed monthly in arrears. Additionally, non-refundable community fees are generally billed and collected in advance or upon move-in of a resident under the Company's independent living, assisted living, and memory care residency agreements. Amounts of revenue that are collected from residents in advance are recognized as deferred revenue until the performance obligations are satisfied.

The Company had total deferred revenue (included within refundable fees and deferred revenue, and other liabilities within the consolidated balance sheets) of $67.3 million and $67.5 million, including $25.2 million and $27.5 million of monthly resident fees billed and received in advance, as of December 31, 2022 and 2021, respectively. For the years ended December 31, 2022, 2021, and 2020 the Company recognized $54.5 million, $60.2 million, and $60.6 million respectively, of revenue that was included in the deferred revenue balance as of January 1, 2022, 2021, and 2020, respectively. The Company applies the practical expedient in ASC 606-10-50-14 and does not disclose amounts for remaining performance obligations that have original expected durations of one year or less.
