I'll bet the CEO can answer all 3 better than any of us can. :)
But I'll give it a try...
1. CEO did buy last year at higher prices. Dunno why not this year.
2. There's no evidence of any options being cashed in, especially since all of the options in the filings are at prices substantially higher than the current price.
3. As of the last conference call, the line of credit still had well over $1 million available on it as it was a secured line of credit based on their accounts receivable. There's always a danger of any line of credit being pulled I guess, but I'm not an expert on that.
