14. Retirement Plan

On May 31, 2002, the Company established a 401(k) defined contribution savings plan (the “401(k) Plan”) for its employees who meet certain service period and age requirements. Contributions are permitted up to the maximum allowed under the Internal Revenue Code of each covered employee’s salary. The 401(k) Plan permits the Company to contribute at its discretion. For the year ended December 31, 2019, the Company made contributions of $0.2 million to the 401(k) Plan. No such contribution was made for the year ended December 31, 2020 as the Company no longer had employees since July 12, 2019.
