(a)Represents net changes in estimated probable recoveries related to self-insurance, which are recorded in receivables, to present our self-insurance liability on a gross basis. The amount for the nine months ended August 31, 2022 primarily reflected a change in the actuarially determined estimate of probable recoveries largely associated with higher self-insured retention levels in our more recent coverage years, and an insurance carrier’s payment of a portion of a townhome claim settlement reached in the 2022 first quarter.
