Employee Benefit Plans [Abstract]
Employee Benefit Plans	13. Employee Benefit Plans 401(k) Plan We have a 401(k) savings plan (“401(k) Plan”) providing retirement benefits to all US employees who have completed at least three months of service. We made matching contributions of each participant's contribution up to 4.0% of each participant’s salary in 2021 and 2020 and 3.5% in 2019. Our contributions approximated $2.1 million, $1.9 million, and $1.6 million for the years ended 2021, 2020, and 2019, respectively. We may make discretionary contributions to the 401(k) Plan, however, no discretionary contributions were made in any of the past three years. Deferred Compensation Plan Our Deferred Compensation Plan (“Deferred Plan”) allows certain of our US employees to defer receipt of a portion of their salary and cash bonus.  The Deferred Plan provides for tax-deferred growth of deferred compensation. Pursuant to the terms of the Deferred Plan, we agree to return the deferred amounts plus gains and losses, based on investment fund options chosen by each respective participant, to the plan participants upon distribution. All deferred amounts and deemed earnings thereon are vested at all times. We have no current plans to match any contributions. Amounts owed to plan participants are unsecured obligations of the Company. We have established a rabbi trust in which it will make contributions to fund our obligations under the Deferred Plan.  Pursuant to the terms of the trust, we will be required to make contributions each year to fully match our obligations under the Deferred Plan. The trust’s funds are primarily invested in Company Owned Life Insurance (“COLI”), and we plan to hold the policies until the deaths of the insured. Our deferred compensation liabilities are recorded as a component of Other current liabilities and long-term Deferred compensation liabilities, as appropriate, on the Consolidated Balance Sheets based on the anticipated distribution dates. The cash surrender value of COLI is recorded in Other long-term assets on the Consolidated Balance Sheets was $6.6 million and $6.4 million as of December 31, 2021 and 2020, respectively. Changes in the value of participant accounts and changes in the cash surrender value of COLI are recorded as part of our operating expenses and are subject to our normal allocation of expenses to inventory and deferred preservation costs. We recorded deferred compensation liability of $378,000 and $68,000 in Other current liabilities and $6.0 million and $5.5 million in Long-term liabilities as of December 31, 2021 and 2020, respectively, in the Consolidated Balance Sheets.
