Sector Commentary

Currencies:  The currencies sector reacted to the pressures the Brexit referendum caused in the fixed-income sector and the Fund benefited from a combination of cross-currency investments.  The British pound fell over 11% immediately after the voting results were announced and only partially recovered against the U.S. dollar by month's end.

Energy:  Crude oil prices moved within a narrow range throughout the month, rose, and ended the month essentially unchanged.  Natural gas prices continued a three-month rise as weather-related demand continued to increase.

Equities:  The global equities markets roiled during post-Brexit trading sessions.  Equities in Europe and Asia experienced sharp declines after the British vote but were able to partially recover value before the end of the month.

Fixed Income:  Yields fell on global debt instruments throughout the month, propelled by the Federal Reserve's decision to delay raising interest rates, and were accelerated by the U.K.'s vote to leave the European Union.  Various U.S., U.K., German, and Japanese fixed-income instruments reached historic-low yields.

Grains/Foods:  Soybean prices traded over a wide price range during the month and ended the month slightly below the intra-month high.  Corn and wheat prices fell sharply during the last two weeks of June as continued moderate weather is creating ideal growing conditions and estimates for this season's crop yield continue to increase.

Metals:  Precious metals markets rose sharply as investors sought safe-haven assets in the uncertainty about the implications and timing of the U.K.'s withdrawal from the European Union.  General uncertainty about the overall strength of the regional economics caused prices to move erratically.
