Movement In Self Insurance Reserve [Roll Forward]      
Adjustments [1] $ (59) $ 6,400 $ (13,096)
[1] 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, and an adjustment to increase our previously recorded liability by
$5.5 million in 2024, $6.5 million in 2023 and $7.0 million in 2022.  The 2022 amount was largely impacted by a change
in the actuarially determined estimate of probable recoveries 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.
