That is 3 years, and considering that it may have been made 2 years ago or more, that is a total of nearly 6 years. Rather long, I suspect and I also suspect that it may have been redated. I have at least one reliable report from someone who scraped off the label on a box of some sheet film (IIRC) and found the same label underneath with a different and much earlier expiration date.
You have no idea how this was kept after any of these companies went belly up either.
I suggest that all of you buying Forte, Agfa and other films and papers from the companies that have ceased production, keep them well refrigerated or frozen until use. You might consider this for any discontinued product. This is just to be on the safe side.
