(a) Notwithstanding any other provision of this subtitle, the board of trustees may authorize a subdivision to remit to the retirement system contributions, deposits, and other payments on the basis of a period that is less than a month, including a weekly, biweekly, or other semimonthly period. A subdivision authorized to remit amounts more frequently than monthly shall make reports and filings and perform other actions accordingly, and the retirement system shall credit payments accordingly.
(b) The board of trustees may make an authorization under Subsection (a) by rule applicable to all subdivisions similarly situated or by order applicable to designated subdivisions. A rule adopted under this subsection is amendable or revocable in the manner provided for adoption, amendment, or repeal of rules generally. An order adopted under this subsection is revocable wholly or partly by subsequent board order.

(c) If the board of trustees adopts a rule or order under Subsection (b), the board shall also adopt rules, applicable to a subdivision electing or designated to take actions described by this section more frequently than monthly, to alter the periods required for submission of payments and reports, including the period when a late penalty begins to accrue or is deducted from a subdivision’s account in the subdivision accumulation fund, in a manner consistent with the periods provided by this subtitle.
(d) A participant may not receive less credited service, service credit, or benefits due to an authorization under this section than the participant would have received on a monthly basis.
