As stipulated in the merchant agreement, A Rolling Reserve, is held on trust, and is designated to stay in your PayTabs account on a rolling xx-days basis, from the date of your last withdrawal. 

Rolling Reserve is a risk management strategy to protect you and your account from potential loss due to chargebacks.  

Upon expiration of the rolling reserve/chargeback holding period and subject to the terms of the Agreement, any remaining amount will be paid to your designated bank account.
Example:  RR of 90 days at 15%.
Explanation: The rolling reserve set is 15.00% for 90 days, which means that the amount will be released after 90 days, on a rolling basis.
