I think it is important to note that the jurisdictions that have gone to accrual-based estimates look at capital spending as well. They all have appropriations for operations, which will include depreciation expenses, but they also have capital spending that they look at.
Those are big amounts, as Stephenie said in her testimony, and they still deserve parliamentary scrutiny, but you also want the departments and agencies to manage the full costs of using public resources, and depreciation is one of those costs. You are using up service potential of an asset.
That cost should be among the costs that a department manages and that you allocate...or give authority to them to use those resources, but you also want Parliament to look at those big dollar amounts for capital spending.
Having a separate appropriation for capital spending is part of an accrual-based estimates process.
