Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk primarily related to potential adverse changes in interest rates, as discussed below. We are actively involved in monitoring exposure to market risk and continue to develop and utilize appropriate risk management techniques. We are not exposed to any other significant financial market risks, including commodity price risk, or foreign currency exchange risk from the use of derivative financial instruments. At times, we use derivative financial instruments to manage our interest rate risk.

We have exposure to changes in interest rates under our revolving credit facility. Our debt with fixed interest rates consists of notes to former owners of acquired companies and acquired notes payable.

The following table presents principal amounts (stated in thousands) and related average interest rates by year of maturity for our debt obligations at December 31, 2022:

The weighted average interest rate applicable to the borrowings under the revolving credit facility was approximately 5.7% as of December 31, 2022 and 1.4% as of December 31, 2021.

We measure certain assets at fair value on a nonrecurring basis. These assets are recognized at fair value when they are deemed to be other-than-temporarily impaired. We did not recognize any impairments in the current year on those assets required to be measured at fair value on a nonrecurring basis.

The valuation of the Company’s contingent earn-out payments is determined using a probability weighted discounted cash flow method. This analysis reflects the contractual terms of the purchase agreements (e.g., minimum and maximum payment, length of earn-out periods, manner of calculating any amounts due, etc.) and utilizes assumptions with regard to future cash flows, probabilities of achieving such future cash flows and a discount rate.
