When becoming GIPS compliant, you need five years, or since inception if you've been in business less than five. Once you are compliant, you need to continue to report the original five years, plus every additional year, until you report 10 years in total. (So the year after you start complying, you'll report 6, the year after that, 7, etc.). Once you're reporting 10 years, you don't need to report any more. So when you have an 11th year to report, you can stop reporting the first year, etc.

It's hard to write out, but it's pretty simple once you grasp it.
