Another thing where we were in the lead was called leasing—buy or lease. Dick Vancil, if you are acquainted with him, did his doctoral thesis on this, and he laid out in there a model for when you should buy, when you should lease. It is still an excellent model.

But until he laid it out, leasing was done strictly by rules of thumb. And they were not very good rules of thumb. So that was a technique.
