A CMO has been issued with 3 tranches and a residual (the residual owns no principal at origination). At origination (same set-up at previous question):

- Tranche A investors own $6,000,000 of principal with a coupon rate of 3.50%.

- Tranche B investors own $4,000,000 of principal with a coupon rate of 3.70%.

- Tranche Z investors own $2,000,000 of principal with a coupon rate of 4.50%.

The residual carries no principal and receives remaining payments. At origination, the mortgages backing the security issued are FRM with mortgage rate of 4.50% with 30 year maturities and MONTHLY payments. Assume no servicing/guarantee fee and no prepayments. Remember to adjust rates to monthly if necessary. Round your answers to cents.

In month 1, what is the mortgage pool's scheduled principal?
