based restricted stock units, which vest in equal tranches in July 2023, July 2024 and July 2025, and (ii) PRSUs, which vest based on the Company’s achievement of revenue and non-GAAP adjusted EBITDA targets for the three-year period ending April 30, 2025. At the award date, target achievement levels for each of the financial performance metrics were established for the PRSUs, at which levels the PRSUs would vest at 100% for each such metric. Threshold achievement levels for which the PRSUs would vest at 50% for each such metric and maximum achievement levels for which such awards would vest at 250% for each such metric were also established. The actual payout for the PRSUs at the end of the performance period will be calculated based upon the Company’s achievement of the established revenue and non-GAAP adjusted EBITDA targets for the performance period. Settlement of the PRSUs will be made in fully-vested shares of the Company’s common stock. For the three months ended July 27, 2024 and July 29, 2023, the Company recorded $865,000, and $661,000 of compensation expense related to the Fiscal 2023 LTIP, respectively. At July 27, 2024, the maximum compensation expense that may be recorded for the performance-based portion of the Fiscal 2023 LTIP is $11,611,000.
During the three months ended July 31, 2021, the Company also granted awards under the Restated 2006 Plan to key employees (“Fiscal 2022 LTIP”). Awards under the Fiscal 2021 LTIP consist of: (i) time-based restricted stock awards, which vest in equal tranches in July 2022, July 2023 and July 2024, and (ii) PRSUs, which vest based on the Company’s achievement of revenue and operating income targets for the three-year period ending April 30, 2024. During the three months ended July 27, 2024, the Company issued a total of 15,427 fully-vested shares of the Company’s common stock to settle the PRSUs in the Fiscal 2022 LTIP. For the three months ended July 27, 2024 and July 29, 2023, the Company recorded no compensation expense and $132,000 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.

For the three months ended July 27, 2024, the Company recorded a provision for income taxes of $1,485,000, yielding an effective tax rate of 6.6%. For the three months ended July 29, 2023, the Company recorded a provision for income taxes of $1,314,000 yielding an effective tax rate of 5.7%. The variance from statutory rates for the three months ended July 27, 2024 was primarily due to foreign-derived intangible income (“FDII”) deductions, federal R&D credits and excess tax benefits from the exercise of stock options and vesting of equity awards. The variance from statutory rates for the three months ended July 29, 2023 was primarily due to FDII deductions and federal R&D credits.
