Fair Value Disclosures [Abstract] |
Fair Value Measurements | FAIR VALUE MEASUREMENTS The following assets and liabilities are recorded at fair value on a recurring basis. •We hold mutual fund assets within a Rabbi Trust to cover liabilities in our deferred compensation plan. These assets have prices quoted within active markets and, accordingly, are classified as level 1 within the fair value hierarchy. •We have interest rate swap agreements serving to reduce our interest rate risk on our debt. These agreements can be valued using observable data and, accordingly, are classified as level 2 within the fair value hierarchy. •We anticipate paying additional consideration for certain acquisitions based upon the subsequent performance of the businesses acquired. This liability is based upon our internal assumptions over revenues, margins, volumes, and contract terms. Accordingly, these inputs are not observable and are classified as level 3 within the fair value hierarchy.

The fair values of receivables, prepaid assets, other assets, accounts payable, accrued costs, and other current liabilities approximate the carrying values as a result of the short-term nature of these instruments. The carrying value of our debt is consistent with the fair value as the stated interest rates in the agreements are consistent with the current market rates used in notes with similar terms in the markets (Level 2 inputs). Other long-lived assets are reviewed when events indicate they may no longer be able to recover their value. Assets that we cease using or which do not appear able to generate sufficient future cash flows to support their values are reviewed and, where necessary, their value is written down. In this instance, the expense is reported in the same place where future expenses were anticipated to be recorded. For example, a fixed asset impairment would be recorded in depreciation expense. All the non-recurring fair values are considered Level 3, as the inputs are not observable and based on internal assumptions. During the year ended September 30, 2023, we recorded impairment charges of $9.5 million. For the year ended September 30, 2021, we recorded impairment charges of $12.5 million. We did not record impairment charges in the year ended September 30, 2022. These impairment charges were on our long-lived assets within our U.S. Services and Outside the U.S. Services Segments and relate to assets on underperforming contracts.
