Disaggregation of Revenue

The Company disaggregates its revenue from contracts with customers by payor source, as the Company believes it best depicts how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors.

The Company has not further disaggregated management fee revenues and revenue for reimbursed costs incurred on behalf of managed communities as the economic factors affecting the nature, timing, amount, and uncertainty of revenue and cash flows do not significantly vary within each respective revenue category.

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. Additionally, non-refundable community fees are generally billed and collected in advance or upon move-in of a resident under 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, deferred liabilities, and other liabilities within the consolidated balance sheets) of $72.5 million and $106.4 million, including $38.9 million and $50.6 million of monthly resident fees billed and received in advance, as of December 31, 2019 and 2018, respectively. For the years ended December 31, 2019 and 2018, the Company recognized $94.6 million and $82.1 million, respectively, of revenue that was included in the deferred revenue balance as of January 1, 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.

For the years ended December 31, 2019 and 2018, the Company recognized $15.2 million and $17.6 million, respectively, of charges within facility operating expense within the consolidated statements of operations for additions to the allowance for credit losses.
