Custom Rules are Boolean expressions – one or more logical statements evaluating variables joined by AND’s and OR’s.  Boolean expressions always result in either True or False.  The result (True or False) determines the action - usually a change to the Tier, Loan Amount, Rate, or Decision (Approved, Referred, or Declined).

 

The simplest rules involve using any number of statements linked together only by AND’s or only by OR's.  When using only AND’s or only OR’s (and not both in a single expression) these statements can be chained together without need for clarification.
