IRD: Interest Rate Differential or IRD is the difference between your actual mortgage Interest rate and ATB’s current mortgage interest rate* for the term closest to the length of time remaining in the mortgage term. This difference is then multiplied by the mortgage balance and residual term.
ATB’s current mortgage interest rates are subject to change without notice. The estimated IRD is based upon the current mortgage interest rate on the day the estimate is obtained and will change on the payout date if ATB’s then current mortgage interest rates change
