COMBINE AND OR with IF Function in Single Formula

[analyst]

My current Formula is as under

=IF(AND(Z6>=2.5,AA6>AA5,AA5>AA4),"New","Ignore")

Now, within same formula, if above condition is not met BUT following condition is true, then also, it should return, "New"

=IF(AND(Z6>=2.5,AA6>=AA4*0.90,"New", "Ignore")


So, if either of the condition is True, like

Condition 1) =IF(AND(Z6>=2.5,AA6>AA5,AA5>AA4),"New","Ignore")

OR

Condition 2) =IF(AND(Z6>=2.5,AA6>=AA4*0.90,"New", "Ignore")

Formula should return 'New', else 'Ignore'

How to combine two criteria AND OR with IF statement in single formula? Sample File attached.
