Im really busy with year-end work and would value your input regarding the Wavey acquisition. This would be a big investment for us and owning Wavey would mean that Windy was operating in a different technology sector. Were Windy to buy Wavey it would cost in the region of 35 million, which we would need to borrow. Our bankers are willing to lend us that sum, but at an interest rate of 11% pa.
