I think we have two forms of leads programs.
We have a classic leads program, in which people would write in and provide information. We're not able to keep in touch with those taxpayers. We're not able to tell them what the outcome is. Those vary, from some very good leads to perhaps just disputes between neighbours or family members. Some of them are of relatively low quality, and the information is not helpful to either start an audit or to finalize one.
The second is the offshore tax informant program that started in 2013. It's a very different program, under which we sign a contract with the informant. They receive a percentage of the funds collected. That's the program that already has almost $95 million identified directly, which is already billed, and that has another $100 million in the hopper.
I would say we have a two-tiered process. One is for serious offshore issues that involve financial reward, and then there is a more general program. There results of the two have very different flavours.
