 contribution 401(k) retirement and savings plan (the “Plan”) to provide retirement benefits for all eligible employees. With limited exceptions, all employees over the age of 21 on the first day of the month immediately following the month of hiring are eligible to participate in the Plan. The Plan allows eligible employees to make salary-deferred contributions up to 75% of their pre-tax annual compensation, as defined in the Plan, as long as the total contributed does not exceed the annual maximum allowable amount under the Internal Revenue Code. The Company makes a semi-monthly matching contribution of 100% of the employee's contribution for that pay period, up to a maximum of 4% of the employee's eligible gross compensation for that pay period. Company contributions vest ratably based on years of service over a four year period, beginning with the completion of the first year of service. For the years ended December 31, 2024, 2023, and 2022, we incurred $12.8 million, $12.9 million, and $11.5 million, respectively, in contribution expense related to employer matching contributions. 

16. Investments and Fair Value MeasurementsFair Value MeasurementsU.S. GAAP establishes a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The hierarchy requires us to use observable inputs when available and to minimize the use of unobservable inputs when determining fair value. The three tiers are defined as follows:•Level 1 - Observable inputs based on unadjusted quoted prices in active markets for identical assets or liabilities;•Level 2 - Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and•Level 3 - Unobservable inputs for which there is little or no market data, and which require us to develop our own estimates and assumptions reflecting those that a market participant would use.The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs. There were no instruments measured at fair value on a recurring basis using significant unobservable inputs during the years ended December 31, 2024 and 2023.The valuation techniques that may be used to measure fair value are as
