Question

Goodwill impairment of 100 — 3-statement impact (with the tax nuance)?

Answer

A goodwill impairment is usually NOT tax-deductible (tax goodwill and book goodwill differ). Assumption here: not deductible.

ItemΔ
Impairment (other operating exp.)+100
EBIT−100
Taxes (no tax shield)0
Net income−100
ItemΔ
Net income−100
+ Impairment (non-cash)+100
= OCF0
AccountΔ
Goodwill−100
Cash0
Retained earnings−100

The change in assets −100 equals the change in equity −100 — the balance sheet balances with no cash movement.

With ordinary D&A you get the tax shield, so cash rises by the tax effect. With a goodwill impairment there is no tax shield (not deductible), so cash is unchanged — the impairment is a pure book-value hit with no cash movement.

Bayer's 2020 write-down of its Monsanto acquisition impaired roughly $9bn of goodwill — no cash effect, but a massive equity hit and covenant pressure. This exact mechanism is why goodwill-impairment risk is presented as a valuation downside in M&A pitches.
