Mergers and acquisitions - Types of M&A by functional roles in market
1
A horizontal merger is usually between two
companies in the same business sector.
The example of horizontal merger would
be if a health care system buys another
health care system. This means that
synergy can obtained through many forms
including such as; increased market share,
cost savings and exploring new market
opportunities.

Competition law - Mergers and acquisitions
The market shares of the merging
companies can be assessed and added,
although this kind of analysis only gives
rise to presumptions, not conclusions.see,
for instance para 17, Guidelines on the
assessment of horizontal mergers (2004/C
31/03) The Herfindahl index|HerfindahlHirschman Index is used to calculate the
density of the market, or what
concentration exists

Merger control - Horizontal mergers
There are two types of anticompetitive
effects associated with horizontal mergers:
unilateral effects and coordinated effects.

The likelihood and magnitude of such an
increase will instead depend on the
substitutability of the products supplied by
the two firms – the closer the substitute,
the greater the unilateral effects.European

Merger control - Non-horizontal mergers
In purely vertical mergers there is no
direct loss in competition as in horizontal
mergers because the parties' products did
not compete in the same relevant market

Vertical effects can produce competitive harm
in the form of foreclosure. A merger is said to
result in foreclosure where actual or potential
rivals' access to supplies or markets is
hampered or eliminated as a result of the
merger, thereby reducing these companies'
ability and/or incentive to compete.European
Commission Non-Horizontal Merger
Guidelines, para. 29 http://eurlex.europa.eu/LexUriServ/LexUriServ.do?uri=

Merger control - Non-horizontal mergers
Two forms of foreclosure can be
distinguished. The first is where the merger is
likely to raise the costs of downstream rivals
by restricting their access to an important
input (input foreclosure). The second is
where the merger is likely to foreclose
upstream rivals by restricting their access to
a sufficient customer base (customer
foreclosure).European Commission NonHorizontal Merger Guidelines, para. 30

Williamson trade-off model

The 'Williamson trade-off model' is a theoretical model in the
economics of industrial organization which emphasizes the
trade-off associated with horizontal mergers between gains
resulting from lower marginal cost|costs of production and the
losses associated with higher prices due to greater degree of
monopoly power.Robert Beynon,

16-21 Guidelines on horizontal mergers
So to take the example, if in market X
company B (with 10% market share)
suddenly bought out the shares of
company C (with 10% also) then this new
market concentration would make the
index jump to 0.162
