[1] At December 31, 2019, the Company recorded insurance receivables of $10.9 million in connection with $10.9 million of litigation reserves recorded. During the three months ended March 31, 2020, $4.2 million was paid by insurance related to one claim and the Company also reduced its insurance receivable estimate by $0.2 million for a separate claim, resulting in an insurance receivable balance of $6.5 million at March 31, 2020, with a corresponding decrease recorded within litigation reserves. For more information, please refer to Note 8.

[2] During 2019, we recorded litigation reserves totaling $5.9 million related to ordinary course litigation which developed and became probable and estimable within the 2019 fourth quarter. Further, as a result of the development of the construction defect related claims within the litigation reserve and their impact to the Company's litigation reserve estimates for IBNR future construction defect claims, we recorded an additional $5.0 million of IBNR construction defect claim reserves resulting in aggregate litigation reserves totaling $10.9 million as of December 31, 2019. Because the self-insured retention deductibles had been met for each claim covered by the $5.9 million reserve, and the self-insured retention deductibles are expected to be met for the $5.0 million IBNR construction defect claim reserves, the Company recorded estimated insurance receivables of $10.9 million offsetting the litigation reserves as of December 31, 2019. During the three months ended March 31, 2020, $4.2 million was paid by insurance related to one claim and the Company also reduced its litigation reserve estimate by $0.2 million for a separate claim, resulting in a litigation reserve balance of $6.5 million at March 31, 2020, with a corresponding decrease recorded within insurance receivables.
