Imagine that you have $$60,000,000$ of notional principal from which floater and inverse floater securities will be created. The underlying mortgages have a WAC of $9\%.$ If the payment rule to the floater class is SOFR$+2\mathrm{.}50\%$ and $$45$MM is the principal balance allocated to the floater class, what is the maximum cap rate on the floater class?
