Conditions:
If the Cusip is coming once, then it's a simple variable.
If the Cusip is coming more than 1, then it's a complex variable.
If condition 2 comes, then the following check is also required:
If in 2 or more Cusips, 1 is prime, then prime will be simple.
If the reset and rate are the same for all, then it's a simple variable.
If the reset is different, then it's directly complex.
If the reset is the same but the rate is different, then it's simple.
