In terms of the Fund's high yield exposure, overweights to financials, pipelines, construction-related and technology sectors were beneficial for results. Security selection in the gaming, services and telecommunications sectors were also additive to performance.With respect to the Fund's emerging markets debt exposure, our overweight to local Brazilian debt contributed to performance during the quarter. In particular, our longer-dated local Brazilian debt with inflation protection generated solid results, as it performed well given the decline in local yields and solid demand. Overweights to higher yielding countries such as Belarus and the Ukraine were rewarded during the last three months of the year. Outlook We have a constructive outlook for the global economy, although pockets of weakness remain. Despite fiscal cliff-related headwinds, we believe that reasonable growth is sustainable in the US. We are less positive on growth in Europe given ongoing issues related to the sovereign debt crisis, high unemployment and extensive austerity measures. Japan also faces continued challenges, as it has fallen back into a recession. We have a generally positive view on the fixed income markets for 2013. In particular, we like the prospects for the credits markets given largely supportive fundamentals and supply/demand technicals. That said, given the amount of spread compression since the financial crisis, credit returns are not expected to be as robust in 2013. As was the case in prior years, we anticipate periods of heightened risk aversion to continue this year, as a number of macro issues remain unresolved. In contrast to developed markets, we maintain a more constructive outlook for emerging markets debt, and anticipate that, within that space, local currencies may lead performance in 2013, but not without potential for periods of heightened volatility.
