When should I use a residual income model instead of a dividend discount model on CFA Level II?

Use the dividend discount model when dividends are a credible proxy for what the company can distribute to shareholders over time. Use residual income when payout policy is not telling the full economic story.

A good residual-income setup usually has three features:

• book value is meaningful
• earnings forecasts are reasonably dependable
• dividends are low, unstable, or intentionally disconnected from value creation

Imagine fictional company Pine Harbor Analytics. It pays a token dividend because management is funding expansion, but its accounting book value is solid and analysts can forecast earnings with reasonable confidence. In that case, DDM can understate value because the dividend is a policy choice. Residual income works better because it starts from book value and asks whether future earnings exceed the required return on equity.

The exam shortcut is:

• DDM if dividends reflect capacity
• Residual income if dividends do not reflect capacity but book value and earnings still matter

If the vignette stresses distorted payout policy or temporarily weak free cash flow, that is often a signal to consider residual income.
