Fund Commentary for the fourth quarter of 2014 from UBS Global Asset Management (Americas) Inc. (“UBS Global AM”), the Fund’s investment manager

Market review

The overall US fixed income market moved higher during the fourth quarter. Despite improving growth and the end of the Federal Reserve Board’s (the “Fed”) asset purchase program, intermediate- and long-term yields declined. In contrast, short-term rates increased given expectations for Fed rate hikes in 2015. All told, the yield on the two-year Treasury rose from 0.58% to 0.67%, whereas the yield on the 10-year Treasury fell from 2.52% to 2.17% during the fourth quarter. In its official statement following its last meeting of the year in December, the Fed stated: “Based on its current assessment, the Committee judges that it can be patient in beginning to normalize the stance of monetary policy.” The overall US bond market, as measured by the Barclays US Aggregate Index, returned 1.79% during the fourth quarter, lifting its 2014 gain to 5.97%.1

Many US spread sectors posted positive total returns during the fourth quarter.2 Among them, long-term investment grade corporate bonds posted the strongest total returns, supported by declining yields over the quarter. In contrast, high yield corporate bonds generated weak results. For the quarter, the BofA Merrill Lynch US High Yield Cash Pay Constrained Index (the “Index”) declined 1.04%.3 From a ratings perspective, BB-rated high yield debt generated the best relative results, as it gained 0.71% for the quarter. Elsewhere B-rated and CCC-rated securities in the Index declined 1.66% and 5.43%, respectively.

Performance review

For the fourth quarter of 2014, the Fund posted a net asset value total return of -2.27% and a market price total return of -7.65%. On a net asset value basis, the Fund underperformed the Index, which, as previously stated, declined 1.04% for the quarter.

The Fund’s exposure to the energy sector was the largest detractor from performance during the quarter. Oil prices started to decline over the summer as the global economic landscape showed signs of slowing, which caused oil demand to weaken. At the same time, oil supply was greater than anticipated, largely due to production from North America. All told, the price of oil fell 46% in 2014. Against this backdrop, the energy sector of the Index declined 10.61% during the fourth quarter and 7.34% in 2014. Elsewhere, the Fund’s exposures to the telecommunications and broadcasting sectors were negative for performance. Finally, the use of leverage was a drag on returns during the period given weak performance from the overall high yield market.

The largest contributor to performance during the quarter was the Fund's allocation to the health care sector. Security selection and having an overweight to this defensive area of the high yield market was helpful. The sector outperformed the Index, as volatility increased during the fourth quarter. The Fund’s underweight to the weak performing metals and mining sector was beneficial for results. Elsewhere, security selection in the services sector contributed to performance.

There were no material changes to the portfolio during the quarter.

Outlook

The US high yield asset class is currently a bifurcated market, with the energy sector trading at elevated spread levels. Within the portfolio, we continue to overweight the energy sector in light of our expectation for supply-driven stability and the eventual recovery of the price of oil. Within energy, we maintain a diverse exposure to many different business models and risk profiles. Beyond oil market fundamentals, we are keeping a careful eye on “falling angels” from the investment grade space (that is, formerly higher rated bonds that were downgraded). Finally, given the fragile state of the high yield sector, large inflows of bond supply would be difficult to manage in the current environment.
