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

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 ancillary 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, deferred liabilities, and other liabilities within the condensed consolidated balance sheets) of $88.3 million and $106.4 million, including $35.5 million and $50.6 million of monthly resident fees billed and received in advance, as of March 31, 2019 and December 31, 2018, respectively. For the three months ended March 31, 2019 and 2018, the Company recognized $61.7 million and $60.9 million, respectively, of revenue that was included in the deferred revenue balance as of January 1, 2019 and 2018.
