Need formula: IF statements to return three possible values(Increase, Decrease, No change)

I have a spreadsheet in Excel 2010 that contains Column A and Column B. Column A is Percentage Decrease. Column B is Percentage increase. I need a column C to return the value "Increase," "Decrease" or "No change" when comparing the two columns.

Example:

A-Percentage Decrease B Percentage Increase C Net Impact
10% 20% Increase
40% 30% Decrease
50% 50% No change

What formula would I insert in Column C to return these values?

Currently, I have the formula: =IF(A>B, "Decrease," "Increase")

This returns correct "Increase" and "Decrease" values, but of course does not return "No change" values. (It returns A = B as "Decrease).

Thanks for your help!

Yes!! That worked :-) Thanks!

Addendum: Some fields have "N/A" or blanks for fields, as we don't have the information. Those return "equals" when I use this formula. Is there a way to make the return value for column C "N/A" in this instance?
