We do try our best to do business in a fair and transparent way. We believe that we do business in a fair and transparent way 99% of the time.
If you think about what we do, we buy products and we sell them, and we negotiate with the people who sell us the product for the lowest possible prices. That can lead to tension. Those tensions, despite the best will in the world, can perhaps lead to bad judgment—bad judgments on both sides.
As an example, I think we've commented on this. We've seen a number of what we would consider to be unjustified cost increases that have been put through or requested by vendors over the last number of months, so it's really important that any code or any set of practices that we engage in is properly balanced.
From our perspective, we are implementing changes today based on feedback we get from vendors to improve that transparency regardless of whether we have a code of conduct. If we have one, and that one works effectively for all sides, that's terrific, but it won't stop us from changing our policies and programs to minimize those incidents where poor judgment is used.
