Contract Balances

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. A portion of the Company's reimbursement from Medicare for certain healthcare services is billed near the start of each period of care, and cash is generally received before all services are rendered. The amount of revenue recognized for periods of care which are incomplete at period end is based on the Company's historical average percentage of days complete on each period of care and any unearned amounts are deferred and recognized when the service is performed. 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 $138.3 million and $72.5 million, including $21.1 million and $38.9 million of monthly resident fees billed and received in advance, as of December 31, 2020 and 2019, respectively. Such amount of total deferred revenue as of December 31, 2020 also includes $87.5 million received during the year ended December 31, 2020 under a temporary expansion of the Accelerated and Advance Payment Program administered by CMS. Refer to Note 3 for additional information on such program. For the years ended December 31, 2020, 2019, and 2018 the Company recognized $60.6 million, $94.6 million, and $82.1 million respectively, of revenue that was included in the deferred revenue balance as of January 1,

2020, 2019, and 2018, 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.
