                          Market Commentary

Financial assets gained during the first half of 2003 amid a revival of risk appetites as anxiety about the war in Iraq faded. Assets that generally benefit from economic growth, such as stocks, corporate bonds and emerging-market debt, fared the best for the quarter and year-to-date as investors returned to these sectors in anticipation of a recovery in the second half of 2003.

Reflationary forces that investors expected to fuel a rebound included federal tax cuts and a weak dollar, as well as low borrowing rates that eased the burden of high personal and corporate indebtedness. Low mortgage rates kept refinancings booming in the second quarter and put money in consumers' pockets. Corporate bond yields were so low that well-known companies such as General Electric and Wal-Mart could borrow for five years at less than 3%.

Treasuries lagged their riskier counterparts but still enjoyed a modest rally. Yields fell to levels not seen in 45 years early in the quarter before bouncing off their lows in June as hopes for recovery increased. The yield on the benchmark 10-year Treasury closed the quarter 0.28% lower at 3.52%, after nearing 3% earlier in the period. Buyers were encouraged that inflation would remain tame amid low capacity utilization and weak employment growth. Asian central banks bought Treasuries to limit the rise in their currencies versus the dollar in an effort to protect their export industries.

Late in the quarter, the Federal Reserve cut the federal funds rate by 0.25% to 1%, its 13th easing since 2001, in an effort to boost the economy and ward off deflation. Although the cut was less than markets expected, the central bank suggested that rates would stay low until deflation risks abated.

The Fund's portfolio of commercial mortgage backed securities ("CMBS") posted a 1.98% return for the second quarter based on net asset value and a 3.13% return based on its NYSE share price. In comparison, the Lehman Brothers Aggregate Bond Index (which includes Treasury, investment-grade corporate and residential mortgage-backed securities) returned 2.50% for the same period. The Fund maintained an uninterrupted and constant dividend throughout the quarter, holding the monthly per share rate steady at $0.09375. These dividend payouts equate to an annualized dividend yield of 7.92% based on the Fund's NYSE trading price as of June 30, 2003.
