GIPS compliance - years of historical returns

To clarify, when they say you need to present 5 years of historical returns or since inception if less than 5 yrs… is this referring to 5 years of compliant returns or any?

Example:
Y1: 2014 non compliant. - firm inception
Y2: 2015 non compliant
Y3: 2016 non compliant
Y4: 2017 non compliant
Y5: 2018 compliant
Y6: 2019 compliant
Y7: 2020 compliant - Claims GIPS Compliance at end of this year

Would this example be in violation if they claimed GIPS compliance ending 2020 and presented 3 years of compliant returns ( 2020 to 2018) and 2 years of non-compliant returns (2017 to 2016)? Or is this allowed because the requirement is simply 5-years of historical returns, and not necessarily compliant years?

To be compliant in 2020 they would have to show 5 years of performance.

I don’t know how they were presenting their performance between 2014 and 2017, but apparently they corrected it in 2018, which means that in 2018 they showed compliant performance from 2014 on.

Perfect, thank you so much!

My pleasure.
