It certainly has not been a concern. I have to say that we have been paid on time all the way through the financial crisis. Every second of the month, everyone has got the cheque they were supposed to get. We have no complaints. If they have the funds, they certainly have been paying.
The reality is that our customers have a vested interest in making sure the suppliers are paid regularly, because they know we're not in really good shape financially. They don't want to lose suppliers. When a supplier goes down, it's very expensive for the customer to replace that supplier, and they're very aware of that. Our tier one companies are also very concerned. Our best tier one companies don't need any money, but they are actively working with us on this because they're worried about their suppliers.
There are about four tiers in the industry. It's very important that all of them have enough cash to stay healthy. So far we have not seen a need for any kind of assurances. They've kept up to their commercial terms as they stated they would.
