Why? Because that's not how they filed it!  I've worked with the SEC on a daily basis in a legal office - and I can tell you PTSC did not file under these sections "by accident" - they actually do know what they're doing when it comes to staying within SEC guidelines - because they're receiving guidance of course.

See Lambert's Post:

it seems that according to the filing convention used on the 8-K announcing the settlements, they in fact were NOT considered material agreements.  Looking at the 8-K format, PTSC was filing under sections 8.01 & 9.01 which are:

Section 8 - Other Events

Item 8.01 Other Events

Section 9 - Financial Statements and Exhibits

Item 9.01 Financial Statements and Exhibits
