• When a sequence of cash flows has only one sign change, only one
solution exists, which the calculator displays.
IRR
• When a sequence of cash flows has two or more sign changes:
– At least one solution exists.
– As many solutions can exist as there are sign changes.
When more than one solution exists, the calculator displays the one
