I wasn't commenting on how it should affect your AA (I view it more akin to a bond or more secure), but merely on how to model it.
I wouldn't put it in as a bond for modeling purposes. You can't rebalance out of it. I'd put it in as income (or subtracted expenses).
Asset allocation takes a lot more into account, especially risk tolerance.
Someone can view it as a bond and go 100% equities in their paper assets, and that's all well and good, if they can handle the swings at the next crash and stick with that AA, rather than deciding at that time they need bonds for a smoother ride, and sell low.
