When, in the Commission's judgment, a construction or preconstruction period (not exceeding five years next following the initial allocation) is justified, no payment on the interest or principal on such loans is required during that period, but interest shall begin accruing on all loan allocations immediately with disbursement. Repayment shall commence no later than one full year following completion of project construction. Any deferred interest may be apportioned over the repayment period. The repayment period will not exceed the project life or fifty years, whichever is less.
