What does this FORD sticker mean?

Below is a scan of a sticker that was affixed to the radiator support of my 4.0 SOHC Explorer. I bought this truck used. Although the handwriting is illegible, I was wondering if anyone knows the meaning and/or implications of this.
Thanks for looking.

Something was done by the dealer

Without knowing the campaign number or other series of numbers its hard to tell.. If your really curious you can ask your local dealer to run a oasis report on your vin.

It may have been a PCM re-flash or something

Excellent, Blee. Thank you for the quick response. I will drop by the dealer, and when I find out, I'll re-post.

I am willing to bet the catalytic converters were replaced. I had mine replaced by the dealer shortly after I bought it 10 years ago and the dealer put that exact sticker on it.

If not the cats then some part of the emissions system was replaced.

Yep, usually a cat, MAF, or ECM recalibration results in a sticker like that being under there.

PCM reflash.

The last 3 letters on the first line are "PCM".

yep looks like it says reprogrammed pcm, and the the line below is probably the revision of software that was put on it.
