## Method and limits

Filter the 504 FOIA file to active FY2010 to FY2016 business loans, estimate maturity from first disbursement plus term, the prepayment-premium end at half the term, and the remaining balance by level amortization at an assumed 4.5% debenture rate.

Not actual loan balances (SBA does not publish them; the balance is a model estimate), not a list of businesses that want to refinance, and no personal contact data: no owner names, phones or emails, no sole proprietors.
