Charlie Munger
Quality Focus
Charlie Munger complemented Buffett's quantitative approach with a multi-disciplinary mental models framework. He advocates paying a fair price for a wonderful business rather than a wonderful price for a fair business. Munger emphasizes understanding the business deeply, identifying durable competitive advantages, and evaluating management quality -- a largely qualitative process supported by quantitative sanity checks.
Valuation Method
Quality-Adjusted DCF
A DCF model that adjusts the discount rate based on business quality. High-quality businesses (strong moats, predictable earnings) get a lower 8% discount rate; average businesses 10%; weaker ones 12%. Uses free cash flow with a 3% terminal growth rate over 10 years.

Intrinsic Value Method
Munger Quality DCF
Sum of [FCF * (1+g)^t / (1+r)^t] for t=1..10 + Terminal Value / (1+r)^10, where r = 8% (high quality), 10% (average), or 12% (low quality)A DCF model that adjusts the discount rate based on business quality. High-quality businesses (strong moats, predictable earnings) get a lower 8% discount rate; average businesses 10%; weaker ones 12%. Uses free cash flow with a 3% terminal growth rate over 10 years.
Verdict Logic
PASS if >= 5 of 7 criteria met, FAIL otherwise. Qualitative criteria (1-3) are auto-passed for quantitative screening, so the verdict depends on the quantitative checks (ROIC, debt, price, capital returns) plus the qualitative foundation.
