AIG’s head-scratching filing…

Every now and then, we come across a filing that truly makes us scratch our head. We’re just not quite sure what to make of it. And that’s exactly how we felt when we came across this Form 4 filed late yesterday by AIG.

Maybe it’s because we don’t spend a lot of time digging into Form 4s — instead, we rely on services like Insider Score for Form 4 crunching — but there’s something that seems odd about a filing made on Oct. 6 that talks about securities in Primus Telecommunications (PMUS) that were disposed of on July 1. Now July 1 happens to be the date that Primus’ reorganization plan was approved. As a footnote in the filing notes, Primus and three subsidiaries filed for Chapter 11 on March 16, 2009.

Or maybe it has something to do with the various news articles talking about another company — Primus Financial Holdings — (which may or may not be related to the other Primus) being the leading candidate to buy AIG’s Taiwanese life insurance unit.

Whatever it is, we’re confused and we don’t admit to that all that often. So if you have a good explanation on why this Form 4 was filed yesterday, we’re all ears. Please post your comments below.
