S&P Global Ratings has identified a criteria misapplication in how we derived our credit ratings on Sixteenth Mortgage-Backed Notes Trust and La Hipotecaria Panamanian Mortgage Trust's series 2021-1, specifically regarding the treatment of Panama’s interest rate subsidies. After reviewing the transactions to correct the criteria misapplication, we affirmed our ratings on Sixteenth Mortgage-Backed Notes Trust's series A, B, and C notes and on La Hipotecaria Panamanian Mortgage Trust's series 2021-1 certificates.
