No need to feel ignorant, it would be a shame if you didn't feel comfortable enough to ask......

Cash On Hand - is what it states, actual cash or cash equivalents (like GIC, T-Bills, short term notes etc) Below 223,663

Working Capital = Current Assets - Current Liabilities (the ability to collect receivables, to sell inventory, to consume prepaid expenses, etc LESS current payables) Below, the Working Capital would be $296,286 less 98,372 approx $200M - this is without any required restrictions on current assets - see Note 16 (c) where we had a restriction on cash of $63M at Dec 2007 to cover first year interest, but we don't have that this year)

You could see that a good portion of working capital is cash. Hope this helps.
