HEVERT Glossary of Frequently Used Terms TERM DESCRIPTION Beta Coefficient A component of the CAPM that measures the risk of a given stock relative to the risk of the overall market. Bond Yield Plus Risk Premium A risk premium model used to estimate the Cost of Approach Equity. The Bond Yield Plus Risk Premium approach assumes that investors require a risk premium over the cost of debt as compensation for assuming the greater risk of common equity investment. Capital Asset Pricing Model A risk premium-based model used to estimate the (“CAPM”) Cost of Equity, assuming the stock is added to a well- diversified portfolio. The CAPM assumes that investors are compensated for the time value of money (represented by the Risk-Free Rate), and risk (represented by the combination of the Beta Coefficient and the Market Risk Premium). Constant Growth DCF Model A form of the DCF model that assumes cash flows will grow at a constant rate, in perpetuity. The model simplifies to a form that expresses the ROE as the sum of the expected dividend yield and the expected growth rate. Cost of Equity The return required by investors to invest in equity securities. The terms “Return on Equity” and “Cost of Equity” are sometimes used interchangeably. Discounted Cash Flow (“DCF”) Model A model used to estimate the Cost of Equity based on expected cash flows. The Cost of Equity equals the discount rate that sets the current market price equal to the present value of expected cash flows. Dividend Yield For a given stock, the current dividend divided by the current market price. Empirical Capital Asset Pricing Model Empirical CAPM is a variant of the CAPM model. (“ECAPM”) ECAPM adjusts for the CAPM’s tendency to under- estimate returns for companies that have Beta coefficients less than one, and over-estimate returns for relatively high-Beta coefficient stocks Flotation Costs Flotation costs are the costs associated with the sale of new issues of common stock. These costs include out-of-pocket expenditures for preparation, filing, ROBERT B. HEVERT - iii - PETITIONER’S EXHIBIT 11 DUKE ENERGY INDIANA 2019 BASE RATE CASE DIRECT TESTIMONY OF ROBERT B. HEVERT TERM DESCRIPTION underwriting and other issuance costs of common stock. Gross Domestic Product (“GDP”) The value of all finished goods and services produced within a country during a given period of time (usually measured annually). GDP includes public and private consumption, government expenditures, investments, and exports less imports. Market Return The expected return on the equity market, taken as a portfolio. Market Risk Premium The additional compensation required by investing in the equity market as a portfolio over the Risk-Free rate. The Market Risk Premium is a component of the CAPM. Proxy Group A group of publicly traded companies used as the “proxy” for the subject company (in this case, Duke Energy Indiana). Proxy companies are sometimes referred to as “Comparable Companies”. Quantitative Easing Quantitative Easing is a monetary policy in which the central bank purchases government securities or other securities from the market to increase the money supply and encourage lending and investment. Return on Equity (“ROE”) The return required by investors to invest in equity securities. The terms “Return on Equity” and “Cost of Equity” are sometimes used interchangeably. Risk-Free Rate The rate of return on an asset with no default risk. Risk Premium The additional compensation required by investors for taking on additional increments of risk. Risk Premium-based approaches are used in addition to the DCF and CAPM to estimate the Cost of Equity. Treasury Yield The return on Treasury securities; the yield on long- term Treasury bonds is considered to be a measure of the Risk-Free Rate. Vertically Integrated Utilities Electric utilities that own and operate distribution, transmission and generation assets. ROBERT B.
