1. INTRODUCTION
ital is a central issue in corporate financial management. For the analyst seeking to evaluate a company’s investment program and its competitive position, an accurate estimate of a company’s cost of capital is important as well. <span>Cost of capital estimation is a challenging task. As we have already implied, the cost of capital is not observable but, rather, must be estimated. Arriving at a cost of capital estimate requires a host of assumptions and estimates. Another challenge is that the cost of capital that is appropriately applied to a specific investment depends on the characteristics of that investment: The riskier the investment’s cash flows, the greater its cost of capital. In reality, a company must estimate project-specific costs of capital. What is often done, however, is to estimate the cost of capital for the company as a whole and then adjust this overall corporate cost of capital upward or downward to reflect the risk of the contemplated project relative to the company’s average project. This reading is organized as follows: In the next section, we introduce the cost of capital and its basic computation. Section 3 presents a selection of methods for estimat

Revenue recognition for sales of real estate varies depending on specific aspects of the sale transaction.19 <span>Under US GAAP, when the seller has completed the significant activities in the earnings process and is either assured of collecting the selling price or able to estimate amounts that will not be collected, a sale of real estate is reported at the time of sale using the normal revenue recognition conditions.20 When those two conditions are not fully met, under US GAAP some of the profit is deferred.

Subject 7. Covariance and Correlation

Variance and standard deviation measure the dispersion of a single random variable. Often times, we want to know the relationship between two variables. For example, what is the relationship between the performance of the S&P 500 and that of U.S. long-term corporate bonds? We can use covariance and correlation to measure the degree to which two random variables are related to each other. Given two random variables, R i and R j , the covariance between the two variables is: Facts about covariance: Covariance of returns is negative if, when the return on one asset is above its expected value, the return on the other asset is below its expected value (an average inverse relationship between returns). Covariance of returns is 0 if returns on the assets are unrelated. Covariance of returns is positive if, when the return on one asset is above its expected value, the return on the other asset is above its expected value (an average positive relationship between returns).
