21050.  (a) An election by a member to receive credit for service
under this part, in addition to his or her current and prior service
credit, shall be effective only if accompanied by a lump-sum payment
or an authorization for payments, other than a lump-sum payment, in
accordance with regulations of the board.
   (b) If a member electing to receive credit for service under this
part is authorized to pay for that service in installment payments
beginning on or after January 1, 2004, the amount of the installment
payments shall include an actuarial adjustment, as determined by the
chief actuary, as necessary to take into account the provisions of
Section 21037.  The amount of the actuarial adjustment may not exceed
one-half of 1 percent of the total installment payment.
21051.  (a) A member electing to receive credit for service subject
to this section shall contribute, in accordance with Section 21050,
an amount equal to the following:
   (1) The contributions the member would have made to the system for
the period for which current service credit is granted, assuming
that the rate of contribution under his or her employer's formula at
the rate age applicable to him or her at the beginning of his or her
first subsequent period of service in membership and his or her
compensation earnable on that date had applied to the member during
the period for which credit is granted.
   (2) The interest that would have accrued on those contributions if
they had been deposited at the beginning date of his or her first
subsequent period of service in membership, from that date until the
date of completion of payments.
   (3) If the member is authorized under Section 21050 to contribute
in other than a lump-sum payment, interest on the unpaid balance of
the amounts payable under paragraphs (1) and (2), which interest
shall begin to accrue as of the date of the election to receive
credit.
   (b) The beginning date of the first subsequent period of service,
for purposes of computation of contributions and interest, shall be
deemed to be the end of the period of service credited for a member
who has no subsequent return to service.
21052.  A member or retired former employee who elects to receive
service credit subject to this section shall contribute, in
accordance with Section 21050, an amount equal to the increase in
employer liability, using the payrate and other factors affecting
liability on the date of the request for costing of the service
credit.  The methodology for calculating the amount of the
contribution shall be determined by the chief actuary and approved by
the board.  A member or retired former employee electing to receive
service credit for service subject to Section 21076 or 21077 shall
pay the contributions as described.
21053.  All contributions of a member under this article shall be
deemed to be and shall be administered as normal contributions.
21054.  Notwithstanding any other provision of law, a member or
retired member who elected to purchase military service credit under
Section 21024 or 21027 on or after January 1, 1999, and prior to
January 1, 2001, may, at any time prior to making the final payment
for the service credit, elect to have the cost of that service credit
recalculated pursuant to Section 21052.  If that cost as
recalculated under Section 21052 is less than the cost as originally
calculated, the member or retired member shall pay the lesser amount,
with credit for the payments previously made.  However, no refund
shall be payable to a member or retired member as a result of the
recalculation of cost pursuant to this section.
