1. Weights:
Generally speaking, a company's assets are financed by debt and equity. We need to calculate the weight of equity and the weight of debt.
The market value of equity (E) is also called "Market Cap". As of today, Tokyo Board Industries Co's market capitalization (E) is 円914.933 Mil.
The market value of debt is typically difficult to calculate, therefore, GuruFocus uses book value of debt (D) to do the calculation. It is simplified by adding the latest one-year quarterly average Short-Term Debt & Capital Lease Obligation and Long-Term Debt & Capital Lease Obligation together. As of May. 2026, Tokyo Board Industries Co's latest one-year quarterly average Book Value of Debt (D) is 円7416.7602 Mil.
a) weight of equity = E / (E + D) = 914.933 / (914.933 + 7416.7602) = 0.1098
b) weight of debt = D / (E + D) = 7416.7602 / (914.933 + 7416.7602) = 0.8902
2. Cost of Equity:
GuruFocus uses Capital Asset Pricing Model (CAPM) to calculate the required rate of return. The formula is:
Cost of Equity = Risk-Free Rate of Return + Beta of Asset * (Expected Return of the Market - Risk-Free Rate of Return)
a) GuruFocus uses 10-Year Treasury Constant Maturity Rate as the risk-free rate. It is updated daily. The current risk-free rate is 2.65%. Please go to Economic Indicators page for more information. Please note that we use the 10-Year Treasury Constant Maturity Rate of the country/region where the company is headquartered. If the data for that country/region is not available, then we will use the 10-Year Treasury Constant Maturity Rate of the United States as default.
b) Beta is the sensitivity of the expected excess asset returns to the expected excess market returns. Tokyo Board Industries Co's beta is 0.3144.
c) (Expected Return of the Market - Risk-Free Rate of Return) is also called market premium. GuruFocus requires market premium to be 6%.
Cost of Equity = 2.65% + 0.3144 * 6% = 4.5364%
3. Cost of Debt:
GuruFocus uses latest TTM Interest Expense divided by the latest one-year quarterly average debt to get the simplified cost of debt.
As of May. 2026, Tokyo Board Industries Co's interest expense (positive number) was 円114.832 Mil. Its total Book Value of Debt (D) is 円7416.7602 Mil.
Cost of Debt = 114.832 / 7416.7602 = 1.5483%.
4. Multiply by one minus TTM Tax Rate:
GuruFocus uses the most recent TTM Tax Expense divided by the most recent TTM Pre-Tax Income to calculate the tax rate. The calculated TTM tax rate is limited to between 0% and 100%. If the calculated tax rate is higher than 100%, it is set to 100%. If the calculated tax rate is less than 0%, it is set to 0%.
The latest calculated TTM Tax Rate = 17.97 / -221.196 = -8.12%, which is less than 0%. Therefore it's set to 0%.
