I'll try to answer what I understand.
First of all, there's a company purchase program that was put in place a long time ago. It's completely at arm's length and depends only on the price of the stock. It's run by our board of directors; I don't run it. I don't know when they're buying or selling shares. They inform us at the end. It's a stand-up procedure under the laws of Canada. That's the way the share purchase program works.
As far as my own share holding, I am demanded by the board of directors to own at least five times my salary in shares to make sure I represent the shareholders. I bought those shares and reinvested most of my salary in MDA in the last 10 years in shares. The shares go up and down and I benefit or lose, just like every other shareholder.
