Fair Value Measurements Fair Value Measurements
The fair value hierarchy established by ASC 820, Fair Value Measurement, prioritizes the use of inputs used in valuation techniques into the following three levels:
Level 1 inputs are observable quoted prices in active markets for identical assets or liabilities
Level 2 inputs are observable, either directly or indirectly, but are not Level 1 inputs
Level 3 inputs are unobservable
The following fair value hierarchy table presents the Company’s assets that are measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022:

(a)Includes money market funds and short-term investments with maturity dates of three months or less when acquired.
(b)Restricted investments, as of September 30, 2023 and December 31, 2022, consist of available-for-sale (“AFS”) debt securities, which are valued based on pricing models determined from a compilation of primarily observable market information, broker quotes in non-active markets or similar assets; therefore, they are classified as Level 2 assets.
(c)Investments in lieu of retention are included in retention receivable as of September 30, 2023 and December 31, 2022, and are comprised of money market funds of $16.3 million and $20.1 million, respectively, and AFS debt securities of $79.4 million and $68.2 million, respectively. The fair values of the money market funds are measured using quoted market prices; therefore, they are classified as Level 1 assets. The fair values of AFS debt securities are determined from a compilation of primarily observable market information, broker quotes in non-active markets or similar assets; therefore, they are classified as Level 2 assets.

The unrealized losses in AFS debt securities as of September 30, 2023 and December 31, 2022 are primarily attributable to market interest rate increases and not a deterioration in credit quality of the issuers. Management evaluated the unrealized losses in AFS debt securities considering factors including credit ratings and other relevant information, which may indicate that contractual cash flows are not expected to occur. Based on the analysis, management determined that credit losses did not exist for AFS debt securities in an unrealized loss position as of September 30, 2023 and December 31, 2022.
It is not considered likely that the Company will be required to sell the investments before full recovery of the amortized cost basis of the AFS debt securities, which may be at maturity. As a result, consistent with the same period in 2022, the Company has not recognized any impairment losses in earnings during the nine months ended September 30, 2023.
The amortized cost and fair value of AFS debt securities by contractual maturity as of September 30, 2023 are summarized in the table below. Actual maturities may differ from contractual maturities because certain borrowers have the right to call or prepay certain obligations.

The carrying values of receivables, payables and other amounts arising out of normal contract activities, including retention, which may be settled beyond one year, are estimated to approximate fair value. Of the Company’s long-term debt, the fair value of the 2017 Senior Notes was $457.5 million and $439.7 million as of September 30, 2023 and December 31, 2022, respectively. The fair values of the 2017 Senior Notes were determined using Level 1 inputs, specifically current observable market prices. The fair value of the Term Loan B was $349.8 million and $389.5 million as of September 30, 2023 and December 31, 2022, respectively. The fair values of the Term Loan B were determined using Level 2 inputs, specifically third-party quoted market prices. The reported value of the Company’s remaining borrowings approximates fair value as of September 30, 2023 and December 31, 2022.
