BETAS AND DEBT MANAGEMENT WITHIN THE UK TAX ENVIRONMENT

Tax complexities relating to corporate tax losses, induced by debt finance, and to the differential tax treatment of equity and sterling debt, are introduced into corporate valuation. The after personal tax value of the geared firm can be less than that of the equivalent ungeared firm. Also, debt-induced tax losses can create negative betas. These fiscal effects are incorporated into degearing formulae under active and passive debt management policies.
