Ann: Trading Halt, page-5

I would say possibly (imo) 2 reasons:

1) given the chairman's comments in earlier interviews, they need more working capital to up-scale production. Business is booming and they need working capital to take advantage of increased business;
2) maybe a foreign body wants a greater slice of the pie in return for increased business?

Just 2 random thoughts off the top of my head. I see it as a really good sign. They're not short of cash at current production levels. There must be another motivation. we shall soon see.
