It all comes down to the time value of money, say I have an oil producing property, I plan to make $100 million in revenues over the next 2 years, I can sell 10% for $5 million today to ERHC, have that $5 million in my pocket today, rather than waiting 2 years for $10 million, and I still have 90% of my field, ERHC coughs up the $5 million today, but gets a cash flow of $10 million over the next 2 years.
