Contract Related Intangibles
The favorable contract asset and unfavorable contract liability in the foregoing table represent the fair value of ADGE's customer contracts (both positive for favorable contracts and negative for unfavorable contracts) which were acquired by us on May 18, 2017. The customer contract asset includes the maintenance services contracts acquired by us on April 1, 2023 as part of the Aegis acquisition and pursuant to the February 2024 Amendment and the May 2024 Amendment. See Note 7. "Aegis Contract and Related Asset Acquisitions."
Amortization of intangibles including contract related amounts is calculated using the straight-line method over the remaining useful life or contract term, which range from approximately one year to eleven years, and is charged against either administrative expenses or cost of sales in the accompanying condensed consolidated statement of operations. Aggregate future amortization over the next five years and thereafter is estimated to be as follows:
