[1] The O&O expenses component of early withdrawal penalties are applied as a reduction to O&O expenses to be repaid by RMC to members’ capital on scheduled redemptions. The amounts credited are determined by the ratio between the amount of the formation loan and the amount of offering costs incurred by the company.
