 1. The definition and formula of intrinsic value

Warren Buffett:"Intrinsic value is the number that you get if you can predict all the cash the business can give you between now and judgement day, discounted at a proper discount rate"

Formula: Discounted present value of future cash

Earnings; Growth; Time

Factors: 1. Earnings, 2. Growth, 3. Certainty, 4. Discounted rate. How do we get those?

Cash available for distribution =  reported earning + depreciation and other non-cash charges (capitalized expenditures for the business to maintain its operations as is + additional working capital needed)
