(1) As part of our assessment of goodwill in 2020, the fair value of the reporting units was determined using an income based approach that utilized unobservable Level 3 inputs, including significant management assumptions such as expected awards, forecasted revenue and operating margins, weighted average cost of capital, working capital assumptions and general market trends and conditions.

(2) The customer relationships' valuation approach utilized unobservable Level 3 inputs including ranges of assumptions of long-term revenue growth from 2% to 5.5% with a weighted average of 2.4%, weighted average cost of capital of 12% and a customer attrition factor of 10%.

(3) The fair value of the Stork and AMECO assets were determined using a combination of observable level 2 inputs in 2021, including indicative offers and ongoing negotiations for the related assets, and an income based approach that utilized unobservable Level 3 inputs in 2020, including significant management assumptions such as expected awards, forecasted revenue and operating margins, weighted average cost of capital, working capital assumptions and general market trends and conditions.
