Different accounting frameworks produce markedly different views of the same asset base. Regulatory asset values (RAV), historical cost accounts, and current cost accounts (modern equivalent asset value, MEAV, or replacement cost), each serve distinct purposes.

That question goes to the heart of depreciation. As discussions at the March roundtable underscored, it is emerging as a central lever in infrastructure economics and regulation.
