Yes, if a market participant would be subject to the top-up tax and would locate the debt to finance the CGU in a jurisdiction that triggers the top-up tax.
Companies commonly use the weighted-average cost of capital (WACC) formula to estimate a post-tax discount rate. The WACC incorporates the market’s view of how a company would structure its financing using both debt and equity.
However, the top-up tax may not always impact both the tax cash flows and the WACC. The WACC formula uses the tax rate of the jurisdiction in which the market participant would locate the debt used to finance the CGU’s operations. Therefore, the impact of the top-up tax on the WACC will depend on the jurisdiction of the debt.
- If the debt would be located in a jurisdiction that does not trigger the top-up tax – i.e. with an effective tax rate for the purposes of Pillar Two top-up taxes greater than or equal to 15 percent – then the tax rate in the WACC is not impacted.
- If the debt would be located in a jurisdiction that triggers the top-up tax – i.e. with an effective tax rate for the purposes of Pillar Two top-up taxes under 15 percent – then the tax rate in the WACC is impacted.
The corporate tax rate used in a WACC calculation represents the relevant tax rate for calculating the after-tax cost of debt. In our view, this rate should reflect upcoming changes in income tax laws when sufficient information is available about these changes to allow a market participant to reflect them. If upcoming changes in income tax laws impact both the tax cash flows and the WACC, then we believe that these upcoming changes to the tax rate should be reflected in the WACC and in the cash flows at the same time.
