buyback of shares

I went to put in a sell order for today and got the following resposnme from CBA broker before placing sell.

"Commonwealth Securities Limited is acting as Broker on behalf of Hills Holdings Limited (HIL) which has launched an on-market buy-back of its shares. Commonwealth Securities is unable to provide any advice in respect of the sale of shares HIL. Please confirm that you still wish for your order to proceed."

Interesting.

Ive decided to put the sell order in at a much higher level due to this.
