Changes in Accounting Estimates |
Changes in Accounting Estimates | 18. Changes in Accounting Estimates ​ During the years ended April 30, 2024, 2023 and 2022, the Company revised its estimates at completion of various contracts recognized using the over time method, which resulted in cumulative catch up adjustments during the year in which the change in estimate occurred. The change in estimate was a result of the Company changing the total costs required to complete the contracts due to having more accurate cost information as work progressed in subsequent periods on the various contracts. During the year ended April 30, 2024, the Company revised estimates to complete two LMS contracts. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was an increase to revenue of approximately $2,672,000. During the years ended April 30, 2023 and 2022, the Company revised its estimates of the total expected costs to complete a LMS contract. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was a decrease to revenue of approximately $1,898,000 and $1,124,000, respectively. During the fiscal year ended April 30, 2023, due to the closure of all of the Company’s MUAS COCO sites, the Company revised the estimated useful life of the MUAS customer relationship intangible asset which resulted in accelerated intangible amortization expenses of $34,149,000, increasing net loss by $26,158,000, or loss per diluted share of $1.04. During the year ended April 30, 2022, the Company revised its estimates of the achievement of the performance metrics of the Company’s long term incentive plans, which resulted in a cumulative adjustment to reduce previously recognized compensation expense of $1,602,000.
