Wallington Asset Management utilizes a four phase
approach in the management of fixed income portfolios. First,
a fixed income strategy is designed to meet each clients
long-term investment objectives. This is more difficult than generally
believed. Each clients liquidity needs, tax considerations
and time horizon constraints are entwined with the investment
objective defined for the portfolio. Objectives may include any
goal in the spectrum from stability of principal and income to
the maximization of long-term nominal returns.
Once these objectives have been defined, Wallington
Asset Management will then establish a duration range to manage
the sensitivity of each clients bond portfolio value to
changes in interest rates. Since most research evidence indicates
that a conservative bond maturity structure allows for the capture
of most of the returns offered in longer-dated maturities while
incurring proportionately less interest rate risk, our preference
is to focus on the intermediate term maturities.
The third phase of our fixed income management employs
the use of prudent portfolio strategies on an on-going basis.
These strategies are drawn from macroeconomic analysis as well
as yield curve and fundamental credit analysis. Our tactics may
take the form of composite duration and convexity adjustment,
shifts to undervalued sectors, and individual bond swaps. We seek
to reap the rewards of credit upgrades and to avoid the risk of
credit downgrades.
Finally, we continually monitor the performance
of each holding as well as that holdings contribution to
the total interest rate risk of the fixed income portfolio. We
believe this fourth step is crucial as we strive to maximize returns
within a predetermined level of risk.
