Clarity needed?

I made an FOI request to the BBC; they have asked for clarification. I am not sure what to say. Here is my request.

I would like to request the following information.

1. For each of the last five years, for the 10 largest currencies, your earnings and expense of foreign exchange.

2. For each of the last five years, the value of business conducted and the identity of the five largest foreign suppliers broken down into intellectual property purchase and sale, network service provision and other items

Is this unclear? Can you help me make it more so?
