Va. Code § 51.1-304
The Commonwealth shall contribute an amount equal to the sum of the normal contribution, any accrued liability contribution, and any supplementary contribution. The amount shall be determined and paid as provided in Chapter 1 (§ 51.1-124.1 et seq.). Notwithstanding the foregoing provisions of this section, member contributions and employer contributions for judges appointed or elected to an original term commencing on or after January 1, 2014, shall be determined under the provisions of the hybrid retirement program described in § 51.1-169. However, during any period that a judge is absent for a period of greater than three months from his duties, the employer shall not make any contributions otherwise required pursuant to subdivision B 2 of § 51.1-169, unless that absence is due to a medical condition, disability, active duty military leave, or family emergency and the existence of the medical condition, disability, active duty military leave, or family emergency is documented in a written communication signed under penalty of perjury by the judge or other authorized representative and submitted promptly to the Virginia Retirement System and the Executive Secretary of the Supreme Court of Virginia.
