The change is just 5% to 6% of JR's position. There was also a comparable reduction of .1M that he did from 3.5M shares to 3.4M shares around last year. I ignored it at that time. Some people make tax retirement changes around this time. That's all I got on VMS.
JR also disposed of 50,000 of his NAN shares on Jan 15/13.
Note: I'm just an ordinary shareholder with no special sources.
