Fund Commentary for the month of September 2009 from UBS Global Asset
Management (Americas) Inc. ("UBS Global AM"), the Fund's investment
advisor
The Barclays Capital Municipal Bond Indexgained
3.59%inSeptember,outperformingUS Treasuries during the month.During
this time, BBB-rated and A-rated securities outperformed their AA- and
AAA- rated counterparts as lower-quality municipal bonds rallied. At the
same time,longer-maturity municipals outperformed intermediate-maturity
and shorter-maturity municipals significantly.
The Fund significantly outperformed its benchmark in September, due to a
relative underweight to shorter-term maturity issues. In addition, an
overweight to the long end (20+ years) of the yield curve benefited
performance. From a credit quality perspective, the Fund's overweight to
AA-rated securities detracted from relative performance, while a
significant underweight to AAA-rated securities helped relative
performance during the month.
Aslight relativeunderweight to both the IDR/PCR(industrial
development revenue bonds and pollution control revenue bonds)
sectorand the tobacco sectorhurt relative performance, especially as
tobacco was the best-performing sector for the month. In addition, an
overweight to hospitals benefited relative performance. The Fund's use
of leverage benefited results, magnifying the impact of
strongperformance during the month.
