settle the PRSUs in the Fiscal 2021 LTIP. For the three and nine months ended January 28, 2023, the Company recorded $36,000 and $228,000 of compensation expense related to the Fiscal 2021 LTIP, respectively.
At each reporting period, the Company reassesses the probability of achieving the performance targets for the PRSUs. The estimation of whether the performance targets will be achieved requires judgment, and, to the extent actual results or updated estimates differ from the Company’s current estimates, the cumulative effect on current and prior periods of those changes will be recorded in the period estimates are revised. No compensation cost is ultimately recognized for awards for which employees do not render the requisite service and are forfeited.
14. Income Taxes
For the three and nine months ended January 27, 2024, the Company recorded a provision for income taxes of $1,259,000 and $3,710,000, yielding an effective tax rate of 8.3% and 6.3%, respectively. For the three and nine months ended January 28, 2023, the Company recorded a benefit from income taxes of $(531,000) and $(8,382,000) yielding an effective tax rate of 67.2% and 38.3%, respectively. The variance from statutory rates for the three and nine months ended January 27, 2024 was primarily due to foreign-derived intangible income (“FDII”) deductions and to federal R&D credits. Historically, the Company calculated the provision for income taxes during interim reporting periods by applying an estimate of the annual effective tax rate (“AETR”) for the full fiscal year to the pretax income or loss for the interim reporting period. For the three and nine months ended January 28, 2023, the Company calculated the provision for income taxes using a discrete effective tax rate (“ETR”) method. The Company determined that due to the fact that small changes in the Company’s estimated pretax income or loss would result in significant changes in the estimated AETR, the historical method would not provide a reliable estimate for the three and nine months ended January 28, 2023. The variance from statutory rates for the three and nine months ended January 28, 2023 was primarily due to a combination of federal R&D credits, the FDII deduction and discrete excess tax benefits resulting from the vesting of restricted stock awards and exercises of stock options.
