Principles of Corporate Finance – A Tale of Value

In Week 1 we propose the game plan for our study of value. Then we analyze the key assumptions for the general valuation model. We focus on the understanding of the sources of value and the fundamental ideas of investor’s choice, the opportunity cost of capital, risk and return. We discuss the importance of time and expectations in determining value. Then we discuss the present value approach to studying the projects’ value and choice. We present the general PV formula and introduce the key concept of net present value (NPV) as a criterion of the choice of good investment projects. Then we study some most widely used shortcuts and apply the formulas to find the NPV’s of certain projects that play a special role in valuation. We end up with the general NPV formula and discuss the challenges in using it.

Week 2 of the Course is devoted to the applications of NPV. In the first part of the week we use NPV to study riskless debt. Of special attention will be the challenges in valuing even riskless bonds. We discuss bond parameters and the special role of yield to maturity. Then we demonstrate how the NPV approach helps determine spot and forward interest rates. The second part of Week 2 deals with the core concepts in valuing equity. We introduce the idea of the common stock value as a function of its cash disbursements. Then we present some formulas that are used to value common stock on the basis of NPV. We focus on growth as a major contributor to the stock value. We analyze growth drivers and the mechanism of growth. On an example we reveal the influence of investments on the stock value. Finally, we pose some questions with respect to NPV approach.

We start Week 3 of the Course by the discussion of criteria of choosing investment projects. Beside NPV, the internal rate of return (IRR) and other approaches are introduced. We show why the NPV criterion is the best and why the application of others may lead to wrong investment decisions. Then we focus on the main ideas to be taken into account while setting up cash flow patterns and making the choice of project on the basis of NPV. We mention some special issues – relevant costs, depreciation, inflation. We present the concept of equivalent annual cost (EAC) as a method of comparing projects of different length. Then we study the application of EAC in greater detail in a case.

In Week 4 we study risk and return. We present a stochastic mathematical model of risk and apply it to find the returns and standard deviations of portfolios of assets. We discuss diversification and the role of special portfolios – the riskless portfolio and the market portfolio – in approaching asset risk. We demonstrate how any asset contributes to the market risk and introduce the β coefficient. Then we derive the capital asset pricing model (CAPM) and study how it is used on examples. We discuss the application of the company cost of capital (CCC) rule to choosing investment projects. Then we use CAPM to determine the cost of capital – first, for an equity-financed company and then in the general case with debt and equity. We present the weighted average cost of capital (WACC) formula and discuss it. Finally, on an example we study the steps in applying CAPM.
