          2. (ii) the issue as to whether such order is a qualified domestic relations order is not resolved,

       2. (B) Each period of qualified military service served by an individual is, upon reemployment under such chapter, deemed with respect to such plan to constitute service with the employer maintaining the plan for the purpose of determining the nonforfeitability of the individual’s accrued benefits under such plan and for the purpose of determining the accrual of benefits under such plan.
       3. (C) An individual reemployed under such chapter is entitled to accrued benefits that are contingent on the making of, or derived from, employee contributions or elective deferrals only to the extent the individual makes payment to the plan with respect to such contributions or deferrals.

In the case of any such treatment, and subject to subparagraphs (B) and (C), any full or partial compliance by such plan with respect to the benefit accrual requirements of paragraph (8) with respect to such individual shall be treated for purposes of paragraph (1) as if such compliance were required under such chapter 43.

       3. (C) Determination of benefits The amount of employee contributions and the amount of elective deferrals of an individual treated as reemployed under subparagraph (A) for purposes of applying paragraph (8)(C) shall be determined on the basis of the individual’s average actual employee contributions or elective deferrals for the lesser of—

    11. (11) References For purposes of this section, any reference to chapter 43 of title 38, United States Code, shall be treated as a reference to such chapter as in effect on December 12, 1994 (without regard to any subsequent amendment).

           2. (ii) the differential wage payment shall be treated as compensation, and
