research and superior stock selection. Principal Global Investors is a member of the Principal Financial Group®.
Philosophy and process
The investment philosophy of Principal Global Investors is based on the belief that stock selection is the most reliable
and repeatable source of outperformance, or alpha generation. The firm believes that disciplined portfolio
construction and the avoidance of unrewarded systematic risks is the key to consistency, or alpha preservation. The
portfolio construction process employs a combination of systematically evaluating company fundamentals and in-
depth original research. Principal Global Investors believes that superior stocks are characterized by companies with
improving and sustainable business fundamentals, rising investor expectations and attractive relative valuations.
To maximize global information advantages, Principal Global Investors employs a unique and powerful research
process combining fundamental insights with systematic disciplines. The firm’s integrated Global Research Platform
serves as a cornerstone of the research process. The Global Research Platform (GRP) contains complex stock
evaluation tools providing a highly customized screening framework based on real time breadth of coverage and peer
rankings encompassing more than 10,000 companies located around the world. These inputs and models include
proprietary analysis and inputs as well as inputs from many of the world's most sophisticated and highly specialized
independent research partners. As an information management tool, the GRP helps to make efficient use of
analysts’ time as they focus on a condensed list of top ranked stocks, in which to conduct in-depth company due
The global research analyst team is organized primarily by sector specialization and further by region. The analysts
are focused on researching the top ranked stocks within their universe, consistent with the investment philosophy.
The insights of the analysts are essential to understanding the business fundamentals at a company-specific and
industry level. This forward-looking professional judgment includes qualitative considerations such as intangibles,
event-driven opportunities, management credibility and the quality and transparency of company financial reporting.
Data integrity and other drivers of quantitative ranks are evaluated with a sample list below:
o Positive Fundamental Change – Analyze revenues, sales, operating margins, earnings potential,
opportunities for positive surprise or continuation of relative improvement. Assess sustainability and identify
potential risks. Review financial statements to assess funding, liquidity, capital risks that could impact
o Rising Investor Expectations – Analyze consensus expectations and assumptions. Review divergent views.
Assess catalysts for positive/negative surprise and the timing of catalysts. Evaluate expectations and
consider earnings estimate revision trends.
o Attractive Relative Valuation – Assess attractiveness of relative valuation and evaluate valuation relative to
expectations, peer group, history, and other top ranking competitors.
All portfolios are broadly diversified and aligned with characteristics similar to the benchmark. The firm’s approach is
intended to provide consistency in style, while isolating stock selection as the primary driver of relative performance

is the key to return consistency.
These concepts are implemented through regionally-integrated teams of portfolio managers and analysts and a
strong reliance on Principal Global Investor’s Global Research Platform. The latter strategy has been utilized by
Principal Global Investors in a variety of equity mandates. Principal Global Investor’s international equity analysts

Spectrum Asset Management offers specialized expertise in the management of preferred securities. Spectrum Asset
Management is an affiliate of Principal Global Investors, with $9.2 billion in assets under management as of
December 31, 2009. The firm was founded in 1987 and is based in Stamford, Conn. Spectrum's clients include
insurance companies, corporations, retirement plans, charitable trusts and financial institutions in the United States
Philosophy and process
Spectrum Asset Management’s specialized approach in the management of preferred securities provides a prudent
alternative for clients who seek diversification opportunities and attractive total rates of return relative to traditional
fixed-income securities, such as corporate, asset-backed and government securities. Its approach is well suited to
clients seeking lower volatility and a higher-quality alternative to high-yield corporate bonds. Spectrum’s success is
the result of capitalizing on inefficiencies found in the preferred market while emphasizing dividend yields of hybrid
preferred securities, which are generally among the highest-yielding investment-grade securities in the U.S. capital
Spectrum’s intermediate-duration strategy emphasizes a rigorous credit approach to identifying superior investment
alternatives. Primary emphasis is placed on investment-grade hybrid preferred securities offering attractive risk-
adjusted yield premiums. Macroeconomic analysis is conducted to identify those economic sectors that are the most
attractive in the near- and long-term future. Spectrum’s research efforts are supplemented by direct access to rating
agency services/industry analysts at major investment banks and the extensive credit research capabilities of
Principal Global Investors.
Attractive issues reflect credit ratings that are steady or improving and offer a premium yield given the ratings and
credit trends relative to other preferred securities. Features such as call protection, subordination or option-adjusted
spreads are assessed to ensure sufficient yield premium to justify their inclusion in the portfolio. Portfolio construction
results in a well-diversified selection of utility, financial and industrial securities.
When market conditions warrant, the portfolio may be hedged to manage interest-rate risk to a targeted duration.
Spectrum’s hedges frequently utilize liquid CBOT-listed Treasury options and futures.
The portfolio holds 275 to 400 separate issues with an average quality rating of BBB+. Annual turnover generally
ranges between 50% and 80%.
Spectrum’s proprietary research is supplemented by direct access to rating agency services, industry analysts at
major investment banks and the extensive research resources of Principal Global Investors. Research conducted by
Principal Global Investors’ core group of 18 credit analysts makes a unique contribution to Spectrum’s preferred
securities research by providing in-depth coverage of over 800 major bond issues. Their analysis of issuers is made
available to the preferred securities research team via the internally developed, real-time bond information tracking
system at Principal Global Investors.
Guggenheim Investment Management, LLC (“GIM”) was founded in 2001, to manage high-yield corporate bond and
bank loan credit strategies. As of December 31, 2009, GIM manages and sub-advises approximately $15 billion for
institutional clients in separately managed accounts, structured vehicles and commingled funds. Most of the assets
under management are for sophisticated investors in longer-term strategies.
Philosophy and process
GIM is a fundamental bottom-up manager specializing in non-investment-grade corporate securities and organized
around industry verticals which place a high degree of importance on industry expertise. GIM believes that its
extensive industry knowledge enables the firm to identify investment themes in industry sectors or companies, which
are then extensively analyzed and ultimately implemented by obtaining exposures at the best point within a capital
GIM’s investment philosophy is implemented through two critical elements: (1) providing downside protection and (2)
maintaining a yield advantage. The downside protection for our high-yield portfolio is primarily achieved by consistent
adherence to our concentrated bottom-up fundamental credit analysis. The yield advantage is maintained through
contrarian investing (a portfolio of higher-yielding issues) with a focus on middle-market companies.
Downside Protection — GIM’s credit team provides a 360-degree perspective of each company, including factors
such as yield potential, industry position, recent events, analyst’s interpretations, technical analysis and prior
experience with the specific company or comparable companies. The mathematics suggest that if the portfolio goes
down 30% (from 100 to 70), it takes a 43% increase to get back to above breakeven (30 / 70 = 42.8%).
Yield Advantage — The value of compounding interest is critical for all fixed-income investments. By definition, the
total rate of return of a fixed-income investment is the compounded value of interest payments plus the present value
of the principal repayment. Approximately 90% of the return associated with high-yield bonds, over a 3-to-5-year
market cycle, is the value of interest payments. Having a 1% to 2% yield advantage in the portfolio, as compared to
the performance benchmark, provides a buffer to difficult periods — such as during 2002 or 2008.
It is important to note that the yield advantage is the result of purchasing issues that are out-of-favor, rather than
through taking additional risk of default. Over time, there historically has been a substantial yield premium associated
with investing in middle-sized issues (as shown in a June 30, 2009 Credit Suisse report showing an ongoing interest
differential based on the size of the high-yield bond issue). In essence, GIM’s strategy is to avoid, or at least
minimize, the risk associated with operating, environmental or regulatory elements while investing in higher-yielding
GIM’s greatest strength is their professional staff of 82 individuals: 52 investment professionals, 7 legal professionals,
13 operations personnel and 10 administrative staff. Investment professionals include credit research analysts,
portfolio managers and traders. The analysts focus on company/industry research and work directly with our staff of
legal professionals. GIM utilizes data tools such as BlackRock Solutions and Wall Street Office to support the trading
and operations teams.
Tortoise Capital Advisors, L.L.C. (Tortoise) is an investment manager specializing in listed energy infrastructure,
such as pipeline and power companies. As of December 31, 2009, Tortoise had approximately $2.8 billion of assets
under management. The firm was founded in 2002 and is headquartered in Leawood, Kansas (a suburb of Kansas
Philosophy and process
Tortoise focuses on the energy infrastructure sector, primarily investing in Master Limited Partnerships (MLPs). The
firm typically invests in companies that transport, store, process and distribute crude oil, refined petroleum products
(gasoline, diesel and jet fuel) and natural gas. These companies effectively connect areas of energy supply with
areas of demand. MLPs tend to generate a stable, high current yield and consistent growth from long-lived, critical
assets operated by strong management teams.
Tortoise seeks to identify and invest in MLPs that generate stable, fee-based revenues with attractive growth
prospects and controlled risk. Tortoise follows a long-term, buy-and-hold philosophy with low turnover in its effort to
achieve a portfolio characterized by high current yield, high growth and low volatility. Tortoise’s security selection
process includes an assessment of the overall attractiveness of the specific segment in which a company is involved,
the company’s competitive position within that segment, potential commodity price risk, supply and demand,
regulatory considerations, the stability and potential growth of the company’s cash flows and the company’s
management track record.
Tortoise’s investment process includes the following three steps:
1. Emphasize higher quality MLPs with good growth prospects and reasonable liquidity
2. Select MLPs with strong management teams
3. Employ a proprietary valuation model to construct portfolio weightings
While primary responsibility for monitoring, review and analysis of individual securities is spread among various
individual members of the investment management team, all portfolio management decisions and reviews are based
on a team approach.
Tortoise has a staff of 32 employees, including a 20-person investment team with deep experience in the MLP
midstream sector. The five members of Tortoise’s Investment Committee have, on average, over 23 years of
Tortoise relies primarily on internally generated research to support their deep, fundamental approach to investing.
The firm has developed proprietary financial, risk and valuation models which they utilize to analyze historical results,
forecast future cash flows, assess risk and assess relative value. In addition, the firm supplements its research
through broker, company and third- party research.
