18.  Fair Value Measurements

​

Fair value is defined under US GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy has been established for valuation inputs to prioritize the inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of the three levels which is determined by the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

​

Level 1 – observable inputs such as quoted prices for identical instruments traded in active markets.

​

Level 2 – inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

​

Level 3 – inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar techniques.

​

The Company’s assets and liabilities that are measured at fair value on a recurring basis, by level, within the fair value hierarchy as of March 31, 2024 and December 31, 2023, respectively, are as follows:

​

​

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. Observable or market inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions based on the best information available. The approach to estimating the contingent earn-out associated with the Company’s business combinations uses unobservable factors such as projected cash flows over the term of the contingent earn-out periods.

​

The Company’s investment in treasury bills are measured at fair value on a recurring basis based on quoted market prices in active markets and are classified as level 1 within the fair value hierarchy. The Company’s contingent earn-out

liability is measured at fair value on a recurring basis and is classified as level 3 within the fair value hierarchy. During the fourth quarter of each year, the Company evaluates goodwill for impairment at the reporting unit level. The Company uses qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a goodwill impairment test. This measurement is classified based on level 3 input.

There were no material changes in fair value since the respective acquisition dates associated with the contingent earn-outs.
