This document discusses the growing need for global infrastructure investment totaling over $40 trillion by 2030. Rapid economic growth and urbanization in developing nations is straining existing infrastructure networks and necessitating massive upgrades. Developed nations also need to upgrade deteriorating infrastructure assets. The document outlines the attractive characteristics of listed infrastructure securities as an investment class to help meet this growing need, including stable cash flows, high barriers to entry, and low correlation to other asset classes.

Global Infrastructure
The $40 Trillion Imperative
2010
EDUC ATIONAL SERIES
Rapid economic growth and strains on
existing networks have magnified the
importance of global infrastructure.
Developed nations need to upgrade deteriorating roads, bridges and
electricity networks. Developing nations are investing heavily to support
their fast-growing economies and rising standards of living. The price tag
is expected to total more than $40 trillion globally by 2030.
In this report, we highlight the trends contributing to infrastructure’s
compelling investment thesis, namely:
Population growth and rapid urbanization in developing nations•
Deterioration of existing infrastructure assets in developed nations•
Governments’ growing reliance on private infrastructure financing•
Listed infrastructure’s attractive return characteristics and low•
correlation with bonds and broader equity markets

Infrastructure needs vary by country.
China is the world’s largest importer of soybeans and Brazil is the largest exporter. Yet China•
can’t rely on Brazil to supply the beans it needs when it needs them because of Brazil’s
subpar infrastructure. Most Brazilian soybeans are trucked hundreds of miles across dirt
roads. When they finally arrive at port, there may be further delays as cargo ships await
docking space. Improvements to Brazil’s logistics and transportation networks are estimated
at US$4.5 billion annually.(1)
Canada exports 38% of its GDP: more than C$1.8 billion in goods crosses the U.S. border•
daily, and exports to China are growing an average of 20% a year. To relieve some of the strain
on Canada’s transportation infrastructure, the country’s leaders have committed C$1 billion(2)
to the Asia Pacific Gateway and Corridor, a network of rail, road and port improvements in
western Canada.
Australia is the world's driest continent, and a four-year drought has exacerbated an already•
dire situation. Sheep prices fell 80% in 2007 as ranchers sent record numbers of livestock to
the stockyards rather than let them die of thirst. In response, the Australian government has
accelerated plans to invest US$42 billion in water infrastructure over the next few years.(1)
How a nation responds can lead to private sector solutions and investment opportunities.

What is Infrastructure?
Infrastructure assets provide the framework for economic growth and modernization.
This report will focus on economic infrastructure, which includes the assets of
transportation, energy, utilities and communications companies.
Infrastructure Characteristics
Infrastructure companies typically share the following characteristics:
• Long-lived assets—Electrical grids, natural gas pipelines, water treatment plants,
toll roads and wireless towers are just a few infrastructure assets with long life
spans and stable cash flows.
• High barriers to entry—Building infrastructure assets requires significant capital,
making it prohibitive for most competitors to enter the market.
• Monopolistic structure—Many companies benefit from government regulation
and minimal competition.
Inelastic demand• —Infrastructure provides essential services that tend to be
resistant to economic downturns.
These factors, alone or in combination, have the potential to generate stable growth
and income.

Drivers: Globalization and Urbanization
Economic liberalization over the last two decades has contributed to the growth in
global demand for infrastructure investment. World gross domestic product (GDP)
is projected to grow about 3% per year through 2030, with developing countries—
driven primarily by Brazil, Russia, India and China (the BRIC nations)—outpacing
developed nations, 4% to 2.4%.
Globalization has led to a significant population shift as millions flock to cities in
search of greater economic opportunities; by 2030, six out of 10 people will reside
in urban centers.(3)
The result has been an unforeseen demand for power, water and
transportation that current systems are not equipped to handle. Global electricity
consumption, for example, is expected to double between 2003 and 2030.(4)

In most developing nations, the lion’s share of infrastructure spending will target new
construction as governments strive to expand inadequate networks. In developed
countries, the immediate need is to upgrade and maintain existing infrastructure.(1)
Global demand

demand is diversified
by geography and
by industry.
Global Leaders Weigh in on Infrastructure
Presidents and prime ministers around the world have made infrastructure
creation and upkeep a priority.
Brazil—“As a government priority we have taken on the construction of major
infrastructure projects in our region. More than just a large group of paths of
integration, it will be a channel for development, bringing economic progress to
areas that have been left out of the benefits of modern society.”
–President Luiz Inácio Lula da Silva, 2004
Canada—“In collaboration with the private sector and other levels of government,
our government is embarking on the largest infrastructure development program
in half a century (C$33 billion). Not since the great national transportation mega
projects of the post-war era has the federal government launched such a massive
undertaking.”
–Prime Minister Stephen Harper, 2007
Australia—“Many urban water pipe systems have been laid down a century ago,
leak like hell, resulting in certain cities [having] up to 30% loss in leakage. That’s
why we’ve established a quarter of a billion dollar fund to partner with local
authorities and state governments, where appropriate, to deal with that.”
–Prime Minister Kevin Rudd, 2008

Transit D
Transit use increased faster than any other mode of transportation—up
21% between 1993 and 2002—as federal investment during this period
stemmed the decline of existing transit infrastructure.But reduced
federal spending in real dollars since 2001 threatens this turnaround.

FINANCING INFRASTRUCTURE—
A COMPETITIVE IMPERATIVE
Governments have historically played a major role in financing infrastructure, but
the budget and taxation constraints they face are forcing them to consider a capital
markets solution—namely, privatization.
Privatization is not new. In Europe, public/private partnerships have developed and
operated toll roads since the 1970s, and the United States is following suit. We are also
beginning to see privatization of U.S. airports.
Infrastructure’s emergence as a separate investment class, however, only began to
coalesce in the mid-1990s. Recently, private equity capital has become active in
infrastructure finance, with more than $100 billion raised—primarily in Europe—
since 2006.
Private and Public Market Opportunities
There are two primary methods for investing in infrastructure: direct/private
investments and listed (publicly traded) securities. The latter has a total global market
capitalization of more than $2 trillion.(1)
A portfolio of listed infrastructure securities
provides several benefits: daily liquidity, diversification potential, transparency and the
discipline of the public markets’ corporate governance model.
Two Ways to Invest in Infrastructure
Direct/Private Investments Listed Securities
Nature of Investments Active investment in a few projects Exposure to broad market
Minimum Investment High Low
Expenses Moderate to high Low to moderate
Liquidity
Low: Investments are usually locked
up for a certain period
High: Investments trade on an
exchange and can be liquidated easily
Access
Low: Funds are usually open only to
qualified or institutional investors
High: Securities can be bought in the
open market
Diversification

A WORLD OF OPPORTUNITY
Utilities comprise by far the largest segment of the infrastructure universe on a
market cap-weighted basis. But because some investors prefer a heavier weighting
in non-utilities, UBS created the UBS Global 50/50 Infrastructure Utilities Index,
a managed index that is equally weighted between utilities and infrastructure and
contains 100 companies in developed markets.

How Global listed Infrastructure Securities
May Benefit a Portfolio
Outperformance by an Alternative Investment Sector
Infrastructure company earnings are generally regulated and predictable, with rate
increases often tied to inflation. They may carry a yield that is higher than U.S.
Treasurys and high-grade corporate bonds, but with less volatility than the broader
equity markets.
A Pure Country Play
Investing in global infrastructure is an efficient way to participate in a country’s or
region’s growth. For investors seeking geographic diversification, it is as pure a play on
a local economy as there is. (Please note, however, that diversification cannot ensure
profit or protect against loss in a declining market.)

Master Limited Partnerships—
A Way to Access Energy-Related Infrastructure
Master limited partnerships (MLPs) are publicly traded, tax-efficient limited
partnerships whose investment activities are limited to natural resources,
commodities and real estate. Over the last five years, many utility and energy
companies have divested oil and gas pipelines to energy infrastructure MLPs,
which, due to the stability of the underlying assets, offer attractive yields, long-
term growth and predictable cash flows. MLPs also feature low commodity
price sensitivity and established franchises with high barriers to entry. The
strong demand for new pipeline infrastructure in North America is expected to
drive future demand for MLPs, which currently have a market capitalization of
$115.4 billion.(4)

Low Correlation With Stocks and Bonds
Listed infrastructure securities have historically exhibited a low correlation to stocks
and bonds. Correlation is a statistical measure of how two securities move in relation
to each other. A correlation of +1 means the securities’ returns move perfectly in
tandem; a correlation of -1 means the returns move in opposite directions. If the
correlation is zero, the securities’ movements are considered to be random.
Attractive Valuations Relative to Projected Growth Rates
Global infrastructure companies’ earnings growth has benefited from healthy sector
fundamentals and industry reforms. For example, global utilities are expected to
post annual earnings per share (EPS) growth that exceeds their historical 2% to 3%
average, yet they are trading roughly in line with historical valuations.
With its steady
risk-adjusted return
profile, it is our belief
that infrastructure
should be viewed
as a core holding
in a diversified portfolio.

Multiple Investment Approaches
Whether it is in the form of a separate account or through a mutual fund, we advise
investors interested in infrastructure securities to work with an investment manager
with proven market expertise.
Risks of Investing in Global Infrastructure
Investing in any equity market presents risks. The risks of investing in infrastructure
securities typically include: (i) government regulation of rates charged to customers,
(ii) restrictions on operations and increased costs and delays associated with
compliance with, and changes in, environmental and other regulations, (iii) increased
competition from other service providers and (iv) technological innovations that may
render existing plants, equipment or other products obsolete. Foreign securities also
involve special risks, including currency fluctuations, lower liquidity, political and
economic uncertainties and differences in accounting and disclosure standards. Some
international securities may comprise small- and medium-sized companies, which
can be more susceptible to price volatility and illiquidity than larger companies.
