The dividend paid for the period was $0.13 per share. The fundamentals of the U.S. economy continued to improve during the first quarter, even after fifteen consecutive interest rate increases by the Federal Reserve Board (Fed). The resiliency of the economy has left little spare capacity in the system. With the federal funds rate now only one step below 5.0%, many participants expect the Fed to stop raising rates at about 5.50%, given the continued strength in the economy and inflation at about the top of the Fed's comfort range. The housing market is one area of concern for the Fed, since so much of the economy's recent strength is owed to this key sector. It now appears that record-setting new home sales four years in a row have finally satiated demand. As consumers adjust to a slower pace of home price gains, or outright contraction in some markets, the fear is that consumer spending will adjust downward. The Investment Manager's concern would be greater were it not for the broad-based strength of the job market, combined with vigor in global growth. Wage and salary gains are becoming a key driver of U.S. growth, after several years of asset-based spending from home equity. With oil and other commodities continuing to show price strength, inflation is the other primary worry. Beyond the price of oil, the Moody's Industrial Metals Price Index reached a new peak in March, which is further evidence of global economic vitality. Another often overlooked element to the inflation picture is the slowing pace of productivity. A weaker dollar would also add to domestic inflation and is a distinct possibility with monetary policy in Japan and the EU turning bearish. In addition, new Fed Chairman Bernanke is probably inclined to err on the side of caution to ensure inflation does not get out of control during his first year in office. In the Credit sector, it appears the top of the credit cycle has been reached. As corporate profit growth begins to slow, the high yield delinquency rate is starting to turn up and credit quality, while still strong, is under increasing threat from leveraged buy-outs and other equity-enhancing actions. However, the supply-demand situation remains quite supportive and therefore spreads do not appear to be under imminent threat.

Within the portfolio, the Investment Manager sold some lower quality bonds that were considered fully valued. Among these were Stora Enso and Continental Cablevision. The Auto sector showed some strength after the positive news about the sale of GMAC. The Investment Manager took advantage of this strength by selling the portfolio's GMAC and Ford holdings, and a portion of the portfolio's position in DaimlerChrysler. An American Airlines security which had recovered in value since year-end was also sold during the period. All the sales, with the exception of DaimlerChrysler, were of below investment grade securities. As a result, the portfolio's exposure to the Corporate sector was reduced by approximately 5% and the portfolio's below investment grade exposure was also reduced significantly. ------------------------------ Maturity Diversification YEARS ----- Under 3 25% 3-5 14% 6-10 36% 11-20 9% 21-Over 16% ------------------------------ * The Lehman Brothers U.S. Credit Index is an unmanaged index of all publicly issued, fixed-rate, non-convertible investment grade corporate debt. ------------------------------------------------------------------------------- MOODY'S QUALITY RATINGS* Percentage of Trust's Total Investments Aaa 6% Aa 16% A 17% Baa 35% Ba 10% B 2% Not Rated 14% * Standard & Poor's (S&P) credit ratings are used in the absence of a rating by Moody's.
