An association may withdraw funds from its reserve account to pay for unforeseen or unbudgeted costs that are unrelated to maintenance, repair, or replacement of the reserve components. The board of directors shall record any such withdrawal in the minute books of the association, cause notice of any such withdrawal to be hand delivered or sent prepaid by first-class United States mail to the mailing address of each unit or to any other mailing address designated in writing by the unit owner, and adopt a repayment schedule not to exceed twenty-four months unless it determines that repayment within twenty-four months would impose an unreasonable burden on the unit owners. Payment for major maintenance, repair, or replacement of the reserve components out of cycle with the reserve study projections or not included in the reserve study may be made from the reserve account without meeting the notification or repayment requirements under this section.
