Title 23 › Chapter 6— INFRASTRUCTURE FINANCE › § 604
The Secretary can give a line of credit to a project borrower. That line is a promise to make a direct loan later if certain needs come up for a project chosen under section 602. The money can be used to pay debt service on project bonds, big repair or replacement costs, operation and maintenance, and costs from unexpected federal or state environmental rules. Before offering a line, the Secretary must work with the Office of Management and Budget and any rating agency that gave a preliminary rating to set a capital reserve subsidy. The line can only be funded if the project’s senior bonds get an investment-grade rating from two rating agencies. A line cannot be larger than 33 percent of the expected eligible project costs. Undrawn credit is available for 10 years after the project is substantially complete. Any draw becomes a direct loan and can be made only if the project’s net revenues (including capitalized interest but not required financing reserves) can’t cover those costs. The interest rate must be at least the yield on 30-year U.S. Treasury securities on the date the agreement is signed, unless another part of the law allows otherwise. The line must be paid back from tolls, user fees, public-private partnership payments, or other dedicated revenues that also back the main project bonds. It must include protections for repayment, like a rate promise or coverage requirement, and may have a lien on those revenues. Third-party creditors cannot make claims against the federal government over draws. The borrower may assign the line to lenders or a trustee. A loan from a draw is normally not subordinated to bondholders in bankruptcy, but the Secretary may waive that rule for certain public agencies if strict conditions are met; if waived, the federal subsidy for that loan cannot exceed 10 percent of the loan principal and the borrower must pay the rest. Fees may be charged to cover federal costs. A project that gets a line cannot also get a secured loan or guarantee that would make the federal share exceed 49 percent of eligible costs. Repayment terms are set based on projected cash flow and the asset’s useful life. Repayments must begin no later than 5 years after the 10-year availability period ends and must be fully paid within 25 years after that period ends.
