Board Lot
A standard trading unit as defined in UMIR (Universal Market Integrity Rules). The board lot size of a security on Toronto Stock Exchange or TSX Venture Exchange depends on the trading price of the security, as follows:

• Trading price per unit is less than $0.10 - board lot size is 1,000 units
• Trading price per unit is $0.10 to $0.99 - board lot size is 500 units
• Trading price per unit is $1.00 or more - board lot size is 100 units

Looks like 500 shares at .10 per share is a board lot. 807 lots at .10 is 403,500 shares. Anyway it looks like demand for UC at .10 is outstripping supply by quite a wide margin. Nice to see things looking up. I bought a few more last week but I'm also tapped out unless I rationalize out of something else but I'm pretty happy wiith the cards I'm holding. JMHO.
