As an extreme adventurer, he’s also climbed Mount Kilimanjaro, HALO-skydived above Mount Everest’s summit, broken the sound barrier in a MIG-25 jet and deep-sea dived to the shipwrecked Titanic to have lunch. He even became a certified Russian-trained cosmonaut, rocketed to the edge of space and served as a backup for the “Soyuz TMA-13” NASA flight to the International Space Station.
Establishing residual income allows you to accumulate wealth faster, have a more flexible lifestyle and maintain a diverse financial portfolio. As with any successful investment, hard work is required. With residual income, however, that work tends to be upfront. Once your revenue stream is established, the work and time involved is significantly lower than active income sources. With residual income, you’ll secure funds for your future, have a better idea of where you stand financially and enjoy peace of mind knowing you’re maintaining lucrative, long-term investments.  
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.
