The surcharge shall be in an amount equal to the greater of (a) the sum of: (i) the present value of any funding losses imputed by CoBank to have been incurred as a result of such payment, conversion or failure; plus (ii) a per annum yield of 0.50% of the amount repaid, converted or not borrowed for the period such amount was scheduled to have been outstanding at such fixed rate, or (b) $300.00. Such surcharge shall be determined and calculated in accordance with methodology established by CoBank, a copy of which will be made available upon request.
