EVA is the incremental difference in the rate of return over a company's cost of capital. Essentially, it is used to measure the value a company generates from funds invested into it. If a company's EVA is negative, it means the company is not generating value from the funds invested into the business. Conversely, a positive EVA shows a company is producing value from the funds invested in it.
I’ve never invested in real estate (except to live in), but am always intrigued by communities like FS who seem to have such a passion for it. My intrigue stems back to my earlier comments that the long term trends in appreciation in real estate are simply not very competitive versus equities, despite what Robert Kiyosaki had to say in his book, Rich Dad, Poor Dad.

It's a relatively simple approach to generating passive income, and a pretty lucrative one at that: A recent survey found that nearly nine in 10 publishers consider affiliate programs to be a key part of their overall marketing strategy, contributing to about 20 percent of their annual revenue on average. However, many publishers can get tripped up when it comes to setting up an affiliate store from scratch. With a variety of programs and products to choose from, how do you know which one(s) will best reflect your site and your audience?

Residual income is calculated as net income less a charge for the cost of capital. The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
