Changes in Estimates

Aggregate net changes in estimates reflected an increase to income before income taxes of $23.4 million ($0.74 per diluted share), an increase of $29.8 million ($0.93 per diluted share), and an increase of $44.1 million ($1.30 per diluted share) during fiscal 2023, 2022, and 2021, respectively. The Company uses its statutory tax rate when calculating the impact to diluted earnings per share.

Revenues recognized from previously satisfied performance obligations were $1.7 million for fiscal 2023, nominal for fiscal 2022, and $2.5 million for fiscal 2021. The change in revenues generally relates to final true-up adjustments for estimated award or incentive fees in the period in which the customer’s final performance score was received or when it can be determined that more objective, contractually-defined criteria have been fully satisfied.

Remaining Performance Obligations

As of June 30, 2023, the Company had $9.2 billion of remaining performance obligations and expects to recognize approximately 48% and 72% over the next 12 and 24 months, respectively, with the remainder to be recognized thereafter.
