[1] The Company recorded insurance receivables of $10.9 million in connection with $10.9 million of litigation reserves recorded as of December 31, 2019. 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 incurred but not reported ("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.

[3] In conjunction with the adoption of ASC 842, the Company established a right-of-use asset of $3.1 million on January 1, 2019. For more information, please refer to Note 1 and Note 11.
