Cal. Code Regs. tit. 10 § 2644.6
"Loss development" is the process by which reported losses are adjusted for anticipated payout patterns. Loss development shall be presented as a loss-development triangle, based on the dollar-weighted average of the ratios of losses for the three most recent accident-years, policy-years or report-years available for a reporting interval. Filings shall contain both paid losses and case-specific reserves, stated separately. Loss development shall employ either paid losses or the sum of paid losses and case-specific reserves. The insurer shall submit both the factors and ultimate losses or claims for the paid and incurred loss and the reported and the paid claims development calculations, and shall demonstrate that its selection is the most actuarially sound. Loss development data shall exclude catastrophes. Where the loss development factors within a given line significantly vary by subline, by size of loss, or by coverage, separate loss development factors shall be calculated in accordance with that evidence.
