The state treasurer reserves the right at its sole discretion to set a minimum and/or maximum transaction amount from any subpool and to limit the number of transactions, whether contribution, withdrawal, or transfer, permitted in a day or other given period of time, or whether to pay withdrawal proceeds in kind or in cash. The state treasurer may establish thresholds and defer withdrawals in excess of those thresholds and pay them out on a deferred or delayed basis from any subpool. In addition, the state treasurer reserves the right at its sole discretion to reject any proposed contribution order, and in particular to reject any proposed contribution made by a pool participant engaged in behavior deemed by the state treasurer to be abusive.
