After one year, records are not required to be maintained.
PRIA only goes back 5 years.
If asked to fill out a PRIA form for anything older than five years, just do it. The form will most likely never make it back and is more of HR concern..
I have been asked for a copy of a pay stub in similar situation. They wanted just to verify I worked there even though the company had been out of business for quite some time.
Honestly, this is not even really an issue.
