"Effect of movement in exchange rates oncash held".  

I guess, this mean the company did not leave their cash in a cash deposit for the quarter. Instead, they used the foreign exchange market and buy/sell different currencies with their cash and made money out of it due to exchange rate differential. This shows treasury/account  department is growing the cash pool. They made $192000 by doing that last quarter.
 Well done.!

This is common for companies with foreign connection. My previous company - A Japanese one use to do that a lot. The financial controller will hook up with his FX broker first thing every morning and buy/sell his cash position into other currencies that he sees will make profit. These are large sums (in millions). It can be quite risky if you do not know what you are doing.

If so, AU8 is making their money grow for you
