Fixed-to-Floating Rate financial

"SHARES FIXED-TO-FLOATING RATE NON-CUMULATIVE PREFERRED STOCK"

A fixed-to-floating rate is a type of loan or investment that starts with a fixed interest rate for a certain period, meaning the payments stay the same, then switches to a variable rate that can change over time based on market conditions. This matters because it offers the stability of fixed payments initially, but also the flexibility to benefit if interest rates drop later.
