I took a quick glance at the financial figures from Wescam. Interesting company. I can not make any comments on who the scam artists are as I have not been involved as a customer.
I did notice a couple of things that worry me about WSC.TO. The company's accounts receiveables and inventory have grown much faster than sales the last couple of years. Sometimes that is a warning that 1) they are giving easy sales terms (long time to pay) and 2) the product isn't going out the door. This was a kiss of death at Commodore Computer (and was there for all to see for a couple of years).
These are preliminary observations. Lunch time isn't long enough to do complete due diligence by myself. Perhaps someone has already explored these issues and can provide insight that will save me time. Or perhaps someone can pick up where I have left off at this time. I also did not completely check out these ratios for FLIR so they may be in the same boat.
