The unprecedented suddenness and uncertainty of the impact
brought on by COVID-19 has many businesses re-evaluating their
business strategies, business continuity plans and transaction
proposals. In particular, businesses will need to review pending
acquisition agreements and consider "material adverse
change" or "material adverse effect" (MAC) clauses.
These clauses typically allow a party to walk away from a
transaction where a material adverse change has occurred between
signing and closing.
Definition and Application
MAC clauses are often considered "a term of art" given
the highly contextual interpretation used to describe a potential
event that affects a target business. In the M&A context, a
typical MAC clause may be defined as any change, effect, fact,
circumstance, occurrence or event that, individually or in the
aggregate, is materially adverse to the business, operations,
assets, properties or condition (financial or otherwise) of the
target business,
