One possibility is that TPL, having built up cash assets via its CORE portfolio and maybe one or two "lesser" MMP deals, could acquire PTSC for 10c-15c (i.e. 2x to 3x current market value). At 10c a share that's $41M to find
Another possibility would be for TPL to merge into PTSC and take advantage of PTSC's tax loss carry-forward (which I haven't researched). This might be of benefit to PTSC shareholders IF the deal is structured to that end.
Either way puts MMP ownership in one place and strengthens the leverage against alleged infringers. It also eliminates the PTSC/PDS/TPL bickering (and extravagances) and may placate Chuck Moore. I can see how that would be the ultimate goal.
