For SBA lenders
Short answer
The SBA assesses "prudent lending standards" by reviewing whether the lender applied sound credit judgment, performed adequate due diligence, and adhered to generally accepted commercial lending practices throughout the loan lifecycle.
Prudent lending is a core principle of the SBA 7(a) program, meaning lenders must underwrite and administer loans as if no SBA guaranty existed. This involves thorough analysis of financial statements, collateral, management experience, and projections, and ensuring the loan is creditworthy based on the lender's internal policies and industry best practices.
A lender approves a loan with an extremely weak debt service coverage ratio and insufficient collateral, relying solely on an optimistic projection without historical basis. The SBA would likely find this failed to meet prudent lending standards during a guaranty purchase review, potentially leading to a denial.
Insider move
Lenders must document their underwriting decisions thoroughly, demonstrating a comprehensive analysis of the borrower's ability to repay, collateral, and management strength. Lack of prudent lending is a common reason for guaranty repairs or denials.
