Quiensabe,
You raise an interesting question, and hopefully it does not require too much personal financial information, as that is not my intent. I just would like to understand the economics of your decision and actions.
As I see it, you have two options. Option 1 - Keep Paying and Option 2 Quit Paying
It appears you have chosen Option 1 - Keep Paying. I will assume that you are rational and are trying to make a financial return on your money, capital, and time. Can you tell me if the reason you keep paying the AUM, even though you are prohibited from grazing due to the over grazing state that it is currently in, is because you have done the economic analysis, and determined that the Future Value of running cattle on the alottment is greater than the Present Value of the lease payment, and other required expenses?
Where does this extra "value" come from? If you can't use it to put lbs. on the cattle, why pay it? Does the fact you have the "leased acres" make your base ranch more valuable? Is that where the extra "value" comes from? Or, when you do get to graze the land again, does the below market costs of grazing make it worthwhile to pay for years when you can't? Or, do you get to apply for a "disaster aid" package for drought reasons, based on having the lease?
What happens if you choose Option 2 Quit Paying? Why not quit paying for something you can't use? I run my cattle on private lands, and they seem to enjoy the grass we grow.
Again, I am just trying to understand the economics of your decision, assuming you make rational economic decisions. I don't really care to ask how many cattle you have, nor how many acres (I was taught a long time ago that those questions are the same as asking how much money you make.)
