Table of Contents Contract Balances Remaining Performance Obligations (In Thousands) Customer Contract Liabilities: Deferred Revenue Balance at January 1, 2019 $ 52,674 Annual additions 78,151 Revenue recognized from prior periods (34,436 ) Revenue recognized from current year additions (44,021) Balance as of December 31, 2019 $ 52,368 As of December 31, 2019, the Company had $88.6 million of remaining performance obligations related to claims and non-claims services in which the price is fixed. Remaining performance obligations consist of deferred revenues as well as certain unbilled receivables that are considered contract assets. The Company expects to recognize approximately 70% of our remaining performance obligations as revenues within one year and the remaining balance thereafter. See the discussion below regarding the practical expedients elected for the disclosure of remaining performance obligations. 72 The table below presents the deferred revenues balance as of January 1, 2019 and the significant activity affecting deferred revenues during the year ended December 31, 2019: The Company's deferred revenues for claims handled for one or two years are not as sensitive to changes in claim closing rates since the performance obligations are satisfied within a fixed length of time. Deferred revenues for lifetime claim handling are more sensitive to changes in claim closing rates since the Company is obligated to handle these claims to conclusion with no additional fees received for long-lived claims. For all fixed fee service agreements, revenues are recognized over the expected service periods, by type of claim. Based upon its historical averages, the Company closes approximately 98% of all cases referred to it under lifetime claim service agreements within five years from the date of referral. Also, within that five-year period, the percentage of cases remaining open in any one particular year has remained relatively consistent from period to period. Each quarter the Company evaluates its historical case closing rates by type of claim utilizing a portfolio approach and makes adjustments to deferred revenues as necessary. As a portfolio approach is utilized to recognize deferred revenues, any changes in estimates will impact timing of revenue recognition and any changes in estimates are recognized in the period in which they are determined. When the Company receives consideration from a customer prior to transferring services to the customer under the terms of certain claims management agreements, it records deferred revenues on the Company’s Consolidated Balance Sheets, which represents a contract liability. These fixed-fee service agreements typically result from the Crawford TPA Solutions segment and require the Company to handle claims on either a one- or two-year basis, or for the lifetime of the claim. In cases where it handles a claim on a non-lifetime basis, the Company typically receives an additional fee on each anniversary date that the claim remains open. For service agreements where it provides services for the life of the claim, the Company is paid one upfront fee regardless of the duration of the claim. The Company recognizes deferred revenues as revenues as it performs services and transfers control of the services to the customer and satisfies the performance obligation which it determines utilizing a portfolio approach. The timing of revenue recognition, billings and cash collections result in billed accounts receivables, contract assets (reported as unbilled revenues at estimated billable amounts) and contract liabilities (reported as deferred revenues) on the Company’s Consolidated Balance Sheets. Unbilled revenues is a contract asset for revenue that has been recognized in advance of billing the customer, resulting from professional services delivered that we expect and are entitled to receive as consideration under certain contracts. Billing requirements vary by contract but substantially all unbilled revenues are billed within one year.
