Supplier recoveries were $4.6 million and $3.0 million for the nine months ended September 30, 2020 and 2019, respectively. **Change in estimates for preexisting warranties reflect changes in the Company’s estimate of warranty costs for products sold in prior periods. Such adjustments typically occur when claims experience deviates from historical and expected trends. The Company’s warranty liability is generally affected by failure rates, repair costs and the timing of failures. Future events and circumstances related to these factors could materially change the estimates and require adjustments to the warranty liability. In addition, new product launches require a greater use of judgment in developing estimates until historical experience becomes available. The Company recorded a benefit for changes in estimates of preexisting warranties of $1.2 million, or $0.05 per diluted share, for the three months ended September 30, 2020, and charges of $8.8 million, or $0.38 per diluted share, for the nine months ended September 30, 2020. The Company recorded charges for changes in estimates of preexisting warranties of $2.7 million, or $0.13 per diluted share, for the nine months ended September 30, 2019.
