  DIFFERENTIAL EFFICIENCY
  It is also called managerial synergy or managerial efficiency .
 According to this theory
• if the management of firm A is more efficient than the
  management of firm B and after firm A acquires firm B the
  efficiency of firm B is brought upto the level of efficiency of firm
  A .Efficiency is increased by merger.
• Basis for horizontal merger
• It may be social gain as well as private gain. Lastly level of
  efficiency in the economy will be increased
     INEFFICIENT MANAGEMENT THEORY
•  This is similar to the concept of managerial efficiency but it
  is different in that inefficient management .
• Basis for mergers between firms when unrelated business i.e.,
  conglomerate merger.
• The management in control is not able to manage asset
  efficiently ,mergers with another firm can provide the necessary
  supply of managerial capabilities .
• In this replacement of incompetent managers were the sole
  motive for mergers and also manager of the target company
  will be replaced
    SYNERGY
  Synergy refers to the type of reactions that occur when two substances or factors
combine to produce a greater effect together than that which the sum of the two
operating independently could account for.
 The ability of a combination of two firms to be more profitable than the two firms
individually.
  In this companies can create great shareholders value than if they are operated
separately.
There are two types of synergy:
• Operating synergy
• Financial synergy
                     Operating synergy
  Operating synergy is improved by Economies of scale and Economies of
scope .
Economies of scale :
     it means reduction of average cost with increase In volume or
  production. Because of fixed overhead expenses such as steel
  ,pharmaceutical, chemical and aircraft manufacturing .
 In that merging of company in same line of business such as horizontal
Merger it eliminates duplication and concentrate a great volume of activity
in a available facility .
 In vertical mergers com expands forward towards the customer or
  backward towards the source of raw material (suppliers). By acquiring
  com control over the distribution and purchasing bring in economies of
  scale .
Cont.…..
 Economies of scope:
Using a specific set of skill or an asset currently employed in producing a specific
product or service .
Operating synergy arise from improving operating efficiency through E/C’s of
scale and scope by acquiring a customers ,suppliers ,and compititors.
 Financial synergy
 Impact of merger on cost of capital of acquiring firms or the newly formed firm .
Cost of capital can be reduced with financial synergy.
 Financial synergy occurs as a result of the lower costs of internal financing
  versus external financing. A combination of firms with different cash flow
  positions and investment opportunities may produce a financial synergy effect
  and achieve lower cost of capital.
 Tax saving is another considerations. When the two firms merge, their
  combined debt capacity may be greater than the sum of their individual
  capacities before the merger.
 The financial synergy theory also states that when the cash flow rate of the
  acquirer is greater than that of the acquired firm, capital is relocated to the
  acquired firm and its investment opportunities improve.
 PURE DIVERSIFICATION
 Diversification through mergers is commonly preferred to diversification
  through internal growth, given that the firm may lack internal resources
  or capabilities requires.
 It may be done including demand for diversification by managers and
  other employees ,preservation of organizational and reputational capital,
  financial and tax advantage.
 It is undertaken to shift from the acquiring com core product line or
  market into those that have higher growth prospect .
       Research reveals that investors do not benefited from diversification .
Investors perceive com diversified in unrelated areas as riskier because they
are difficult for mgt to understand.
     STRATEGIC REALIGNMENT To CHANGING
    . ENVIRONMENT
•    It suggests that the firms use the strategy of M&As as ways to rapidly
  adjust to changes in their external environments in regulatory framework
  and technological innovation . When a company has an opportunity of
  growth available only for a limited period of time slow internal growth may
  not be sufficient.
• Technical changes contributes to new products ,industries , market .
• The use of IT technology is likely to encourage mergers which are less
  expensive and faster way to acquire new technology and owner knows
  that how to fill a gap in current offering or to entering new business .
       HUBRIS HYPOTHESIS
Hubris hypothesis implies that managers look for acquisition
of firms for their own potential motives and that the
economic gains are not the only motivation for the
acquisitions. This theory is particularly evident in case
of competitive tender offer to acquire a target. The urge to win
the game often results in the winners curse refers to the ironic
hypothesis that states that the firm which over estimates the
value of the target mostly wins the contest.
 Q-ratio
 The ratio relates the market value of shares to replacement
  value of asset.
 Inflation and high interest rate can depress share prices will
  below the book value of the firm , high inflation may also
  raise replacement cost above the book value of asset .
 Mergers are undertaken when market value of com is less
  than replacement cost of its asset
Information and signaling
The announcement of mergers negotiation or a
 tender offer may convey information or signals
 to market participants that future cash flows are
 likely to increase and that future will increase in
 future values
 Agency problem
 Takeover and mergers would be a threat because of inefficiency or agency
  problem .
 When it takes place where there is a divergence between the goals of
  management and owners
 Market power /share
 Mainly mergers are undertaken to improve ability to
  set and maintain prices above competitive level .
 Increase in the size of the firm is expected to result in
  market share . The decrease in the number of firm
  will increase recognized interdependence
 Managerialism
Managers may increase the size of the firm
 through mergers in the beliefs that their
 compensation is determined by size but in
 practice management compensation is
 determined by profitability
 Tax consideration
 Unused net operating loss of the target com and the
  revaluation or writing up of acquired asset and the tax free
  status of the deal influence M&A .
 Loss carryforward can be setoff against the combined firm
  taxable income.
