May I suggest that you read the frequently asked questions and answers on the PTSC website. First find and click on the tab "Press Room" On the left side of the page you will find frequently asked questions.
In my opinion, voting will not effect by-law changes, however, it does send a message. They have already chosen to ignore majority voting which was passed (overwhelmingly) by shareholders last year. This year's shareholder proposal mandating directors to buy company stock with their own money was allowed on the proxy. However, the BoD stated that even if passed, it will be non binding.
Hope this
helps and good luck.
