There's a fee for the licenses themselves, per contract, and then we have a yearly licensing fee that's many thousands of dollars. But that's not just for TrueSight, that's also for support for ITSM, Atrium Orchestrator, BBNA, and other BMC tools in the environment. We have to support more than just TrueSight in that space. It's a package deal from a support perspective. From a licensing perspective, when we get a contract in we size the contract, do quotes from the contract, and then we engage BMC to say, “This is how many additional licenses we're going to need as a function of that contract.” Then we do the numbers thing. But we've actually dumped a lot of money. I think recently it was about $174,000. But again, it depends on the contract, it depends on what we're dealing with. It's been many thousands of dollars.
