Unbilled receivables as of October 31, 2024 relate to contracts-in-progress for which revenue has been recognized, but for which we have not yet earned the right to bill the customer for work performed to-date. Under ASC 606, unbilled receivables constitute contract assets. In the first quarter of fiscal 2025, we reversed cumulative revenues and associated contract receivables due to changes in estimates of revenue and costs for certain contracts. With respect to such changes in estimates, we: •determined that an unbilled receivable contract asset in the amount of $18,993,000, related to an international customer and reseller of our troposcatter technologies, was at risk of not being invoiced or collected, principally due to our customer's near-term ability to secure certain opportunities in its pipeline. As a result, and considering that we offered a price concession (i.e., variable consideration) to our customer in the first quarter of fiscal 2025, we reversed $1,551,000 of cumulative revenue and associated unbilled receivable contract assets related to this transaction, and recorded a non-cash charge to fully reserve for the remaining $17,442,000 unbilled receivable contract asset within our allowance for doubtful accounts; •reversed $1,004,000 of cumulative revenue and associated unbilled receivable contract assets as a result of being assessed late delivery penalties during the quarter on a separate contract to deliver Modular Transportable Transmission Systems (or "MTTS" troposcatter solutions) to the same international customer referenced above; •reversed $4,157,000 of cumulative revenue and $3,003,000 of associated unbilled receivable contract assets as a result of terminating certain customer contracts during the quarter in connection with the CGC Divestiture; and •reversed $1,360,000 of cumulative revenue and $1,281,000 of associated unbilled receivable contract assets due to higher expected costs at completion identified during the quarter, as we advanced certain nonrecurring engineering related projects in our satellite ground infrastructure product line through development and toward production. After adjusting for those amounts identified above, management estimates that a substantial portion of the remaining contract assets not yet billed at October 31, 2024 will be billed and collected within one year. Accounts receivable in the table above excludes $824,000 of long-term unbilled receivables presented within "Other assets, net" on the Condensed Consolidated Balance Sheets as of July 31, 2024. As of October 31, 2024, the U.S. government (and its agencies), an international customer and reseller of our troposcatter technologies and AT&T, represented 34.7%, 11.6% and 11.4% of total accounts receivable, respectively. There were no other customers which accounted for greater than 10% of total accounts receivable. As of July 31, 2024, the U.S. government (and its agencies), an international customer and reseller of our troposcatter technologies and AT&T, represented 36.4%, 11.3% and 10.9% of total accounts receivable, respectively. There were no other customers which accounted for greater than 10% of total accounts receivable.
