Short-Intermediate U.S. Government Fund

Short-Intermediate U.S. Government

as of June 30, 2010

The second quarter saw a series of events that captured investors' attention and sparked a flight to quality in the bond market. Sovereign debt problems in Europe culminated in the downgrade of Greece's credit rating to "junk" status, while central banks in the region were forced to expend several billion euros to support the sovereign debt markets. On the domestic front, the Federal Open Market Committee downgraded its estimates for economic growth. Despite record low interest rates, it now appears that the Federal Reserve will not raise rates until well into 2011. Anxiety over financial regulation from Washington, worries over municipal debt, and the oil leak in the Gulf added to the dour mood. Resolutions regarding the above-mentioned headlines should be key drivers of market performance during the second half of the year.

Treasuries staged an impressive rally during the quarter due largely to a reduced threat of inflation, the flight-to-quality rally and worsening economic data. Consumer spending, home sales, consumer confidence, global shipping rates, inventory data and payrolls all came in below expectations during the quarter. As the effects of government stimulus wane and the appetite for further stimulus stalls, the strength of the recovery remains very much in question.

The Short-Intermediate U.S. Government Fund returned 1.92% and outperformed its benchmark during the quarter. Our yield curve and duration positioning added positively to performance, while security selection detracted. We continue to focus on investing in liquid assets and we are closely watching economic data for signs of slower-than-expected growth.
