Cost of capital
Weighted average cost of capital and its components
Cost of equity is the risk-free rate plus beta times the equity risk premium, both fixed across every industry in a region, so the only industry-specific input to it is beta. Cost of capital is the equity-weighted cost of equity plus the debt-weighted after-tax cost of debt; both identities were verified against these numbers at build time.

What is missing here
Every field above is populated for this industry in both regions.
This snapshot carries one vintage, 2026-01-05, and no other date column, so nothing on this page can be compared with an earlier or later reading of the same industry. The methodology page lists every trap found in the source.
