dv01’s cashflow engine now features Purchase Rate Vectors to input monthly purchase assumptions (i.e. new/additional principal balances) for a pool or cohort that can be included in saved scenarios. The assumptions can be defined any of three ways upon the end-of-month pool balance:

  • ABS% (Absolute %): adds a fixed % of the initial balance every month, remains constant
  • COM% (Compounding %): adds a % of the current balance each month, growth accelerates
  • ABS$ (Absolute $): adds a fixed dollar amount each month, remains constant




Note: Purchase vectors are gross additions only, actual balances will also reflect prepayments, defaults, amortization, etc.
