"After reviewing financial statements and data on dozens of closed-end funds, we identified MFS Intermediate Income Trust (NYSE: MIN) as one of my top picks," says income expert Carla Pasternak.

In her High Yield Investing, she explains, "You won't find many closed-end funds with a better mix of high-quality bonds than MIN's AA+ rated portfolio." Here's her look at this fund that offers an estimated 9.8% yield.

"MFS Intermediate Income Trust holds U.S. and foreign developed government bonds; it offers a discounted share price and a steady income stream powered by healthy earnings from portfolio assets.

"And like other bond funds, it can be affected by rising interest rates, but its diverse portfolios should help steady returns.

"You won't find many closed-end funds with a better mix of high-quality bonds than MIN's AA+ rated portfolio. The fund invests in AAA-rated U.S. Treasuries and agency bonds, foreign debt of developed countries, and high-grade corporate bonds.

"Management insulates the portfolio assets from currency volatility by holding them in U.S. dollars. A low duration of 4.4 years limits sensitivity to changing interest rates. The fund also may trade derivatives and use leverage to boost returns.
