section heading icon     drivers of M&A

This page discusses some drivers of merger, acquisition and disposal activity as an aid in understanding recent telecommunication booms/busts and the dot-com bubble.

It covers -

It is complemented by a note on the private equity fund industry.

subsection heading icon     introduction


Journalism on the dot-com and telecommunication bubbles has often highlighted monumental valuations of enterprises in the 'new economy' and the awesome disappearance of much of that value, with billions of dollars evaporating in a way that left only a memoir or two, a server farm and the Aeron chairs behind.

More recent deals have featured staggering amounts, with global figures for announced M&A in the first half of 2007 at US$2.8 trillion, up from US$1.9 trillion in the first half of 2006.

As US politician Everett Dirksen (1896-1969) quipped about the US Budget

A billion here, a billion there, pretty soon it adds up to real money.

The following pages of this note highlight where some of the money has gone.

In examining corporate mergers, acquisitions, deacquisitions and collapses over the past century it is possible to identify a number of drivers. They include -

  • a search for economies of scale and scope
  • problems with diseconomies of scale and scope
  • personal and corporate aggrandisement
  • expediency and fashion
  • access to capital, favourable tax regimes and M&A-friendly competition policy

Economist Joseph Schumpeter (1883-1950) famously characterised capitalism as "creative destruction", one of those phrases perhaps more quoted than understood and less celebratory than claimed by neoconservative epigones. Few commercial organisations have lasted for more than three generations; many of the older businesses have shifted focus several times during their period of operation.

subsection heading icon     scale

An argument often used by proponents of mergers is achievement of economies of scale in areas such as procurement, human resource management, information systems, operations, research and marketing.

A complementary argument is that takeovers build a bigger, stronger business, one that -

  • has greater cash flow
  • is more likely to attract talented executives
  • will engage the interest of investors (and secure a wider range of investors)
  • will be able to invest in training its personnel, in marketing, in product development/enhancement or merely in expensive capital equipment such as oil rigs, airliners and state-of-the-art steel mills
  • has the strength to weather financial storms (Kuznets waves, Kondratieff cycles or contingencies such as an inept central bank or the demise of an ally)
  • is in a better position to take risks or "take the long view"

In practice achievement of such gains can be elusive. It is arguable that economies of scale in some sectors can be exhausted when enterprises reach a relatively modest size, with investors in particular enjoying greater returns through stakes in businesses that have stayed 'lean and mean' rather than succumbing to gigantism or the distractions of absorbing associates and competitors.

Critics thus warn of diseconomies of scale and loss of focus, with senior managers for example experiencing difficulty in identifying and interpreting details of an organisation's activity, with consequent duplication of expense, failure of internal controls, delays in decisionmaking and neglect of problems. Coase, in contrast to some of the Coasians, and Chandler in The Visible Hand: The Managerial Revolution in American Business (Cambridge: Harvard Uni Press 1977) noted that for information acquisition, big was not necessarily better. Others have commented that some major enterprises are not taking the long view but instead are driven by the tyranny of the quarterly return.

subsection heading icon     scope

Economies of scope have been claimed as another rationale for M&A, with proponents arguing that 'related' enterprises can -

  • share financial and technical resources resources
  • exchange managers
  • create opportunities for each another, for example 'cross-selling' by bancassurance giants or shared promotion and merchandizing by media conglomerates.

Fashions in corporate strategy and the shape of major enterprises come and go, which might lead to some scepticism about rationality and the eternal truths peddled by management schools (or merely by gurus such as Tom Peters).

In practice opportunities are restricted by factors such as -

  • competition policy
  • the non-fungability of much executive expertise (not all corporate cultures and all markets are the same)
  • inappropriateness (consumers for example resist buying insurance from a fast food outlet, even though that chain and its banking associate are in the "business of service")

Fads for industrial conglomerates appeared and departed during the 1920s and 1970s. More recently we have seen the restructuring of accounting groups that embraced corporate auditing, management consulting and corporate law operations.

Interest in functionally-diverse financial groups - a retail bank with a corporate bank with private banking with funds management with insurance with a credit card processor with mortgage provision - appears to be waning as groups experience difficulty in fully using skills and information gained through different relationships.

subsection heading icon     aggrandisement

A third reason for corporate pursuit of growth through mergers and acquisitions is personal and national aggrandisement.

Chief executives want the gratification of running a larger enterprise or merely the attention associated with a takeover, subordinates on occasion see opportunities (albeit at the expense of peers through post-aquisition 'right-sizing'), corporate boards aspire to leadership and the pilot fish - lawyers, management consultants, publicists, accountants - see opportunities through capture or defence of their client.

Others gratify their egos (and their wallets, along with those of their backers) through what has variously been characterised as asset stripping, downsizing or right-sizing. Uncritical acceptance of 'muscular leadership' or charismatic chief executives - exemplified in mid-career hagiographies of Harold Geneen, Charles Bluhdorn, Samuel Insull, Jack Welch, Al Dunlap, Jean-Marie Messier and Christopher Skase - has been questioned in works such as Rakesh Khurana's Searching for a Corporate Savior: The Irrational Quest for Charismatic CEOs (Princeton: Princeton Uni Press 2002).

Governments (along with other voices such as business journalists, industry organisations and academics) have on occasion encouraged industry consolidation to -

  • achieve economies of scale through aggregation of small enterprises into one of regional or 'world scale'
  • rescue individual ailing enterprises, resuscitate an ailing industry or provide an escape route for investors
  • build 'national champions' in industries that are perceived to be of key national interest (steel, computer hardware, software, biotechnology) in relation to national security or as a driver of economic growth throughout the national economy
  • build national champions in sectors with a symbolic value (eg film in 1930s Britain)

That consolidation may occur across borders, with some governments endorsing - even encouraging - international expansion and others (for example France and Spain) impeding acquisition of major national enterprises.
