The Dividend Discount Valuer

Value this company (or share) based on its expected dividends.

The company: [DESCRIBE]
Dividend info: [CURRENT DIVIDEND, EXPECTED GROWTH, STABILITY]
Required return: [RATE, OR HELP ME ESTIMATE]

Provide:
1. A dividend discount valuation with the method and inputs shown
2. The sensitivity to the growth and required-return assumptions (which
   dominate)
3. Where this model works well and where it breaks (non-payers,
   high-growth, irregular payers)
4. How it compares to a DCF or multiples view for this company
5. The assumptions I should be most sceptical about

Show the maths and be clear this suits stable dividend-payers far better
than growth or non-paying firms.
