SECOND QUARTER 2015 International Bond Fund Quarterly Commentary International Bond declined for the quarter ended June 30, 2015, slightly trailing the return of its benchmark, the Barclays Global Aggregate Bond Index ex-usd. Yields Rose as Global Economic Conditions Improved Bond yields generally rose around the globe in the second quarter. Signs of improving economic growth, particularly in the U.S. and Europe, pushed bond yields higher. In the U.S., the economy contracted slightly in the first quarter, but economic data in the second quarter was notably better. Economic growth in Europe, while still muted overall, continued to move in a positive direction. While yields rose sharply in the U.S. and Europe, yield movements were more subdued in Asia as uncertainty about economic growth in the region kept yields in check. Volatility in the global fixedincome markets increased late in the quarter amid escalating government debt issues in Greece. Objective Total return, primarily through unhedged nondollar bonds. Portfolio Management Team Name, Industry Start Date John Lovito, 1986 Edward Boyle, 1998 Simon Chester, 1989 G. David MacEwen, 1983 Bond markets in the Asia/Pacific region held up the best as yield increases were modest. In Europe, major markets such as the U.K. and Germany fared best, while peripheral markets such as Italy and Spain underperformed. In general, government bonds outperformed nongovernment securities. For U.S. investors, a weaker U.S. dollar aided returns in non-u.s. bond markets. The U.S. dollar depreciated against most major currencies, including 6% against the British pound, 3% versus the euro, and 1% against the Australian and Canadian dollars. The main exception was a 2% increase for the U.S. dollar versus the Japanese yen. Currency and Sector Positioning Detracted The fund s currency positioning detracted from performance as the fund maintained an overweight position (relative to the benchmark) in the U.S. dollar, which weakened against most foreign currencies. An underweight position in the euro, which strengthened, also weighed on results. Sector allocation was a drag on performance, particularly an overweight position in nongovernment bonds, which comprised more than 20% of the portfolio. Within this component, an emphasis on lower-rated bonds issued by European financial companies detracted from performance as the turmoil in Greece put downward pressure on riskier segments of the fixed-income market. Duration Positioning and Country Weightings Added Value The fund s duration positioning aided performance relative to the benchmark. The fund s duration (a measure of interest rate sensitivity) was shorter than that of its benchmark throughout the quarter, and this positioning added value as global bond yields rose. Toward the end of the quarter, the team shifted back to a neutral duration versus the benchmark. The fund s country weightings also contributed positively to relative results. An overweight position in Norway and a corresponding underweight position in the U.K. were favorable for performance, though the team took profits near the end of the quarter, shifting back to a relatively neutral position in both countries. The team also took advantage of volatility in Spain, adjusting the fund s holdings of Spanish bonds when yields fluctuated significantly. At the end of the quarter, the fund held an overweight position in Spain. Positioning for the Future The team expects global economic conditions to improve during the second half of the year. The U.S. is likely to remain one of the stronger economies in the world, but growth also appears to be firming in Europe and selected countries in the Asia/Pacific region thanks to accommodative central bank policies. This environment will most likely result in a short-term interest rate increase by the Federal Reserve (Fed) before year-end. The team has been reducing the fund s overall risk profile and sharpening its focus on areas such as U.S. high-yield bonds, European financial securities, and peripheral European markets such as Italy and Spain. In addition, the fund remains overweight the U.S. dollar given the likelihood of an impending Fed rate hike. The team expects to see greater volatility in the fixed-income and currency markets in the coming months, and will seek to take advantage of opportunities resulting from these market fluctuations.

In a declining interest rate environment, bond prices rise and the fund may generate less income. In a rising interest rate environment, bond prices fall.

Cash and cash equivalents include payable amounts related to securities purchased but not settled at period end. Credit quality ratings on underlying securities of a fund are obtained from three Nationally Recognized Statistical Rating Organizations ( NRSROs ), Standard & Poor s, Moody s and Fitch. Ratings are converted to the equivalent Standard & Poor s rating category for purposes of presentation. The median rating is used for securities rated by all three NRSROs. The common rating is used when two of the three NRSROs agree. The lower rating is used when only two NRSROs rate a security. A non-rated designation is assigned when a public rating is not available for a security. This designation does not necessarily indicate low credit quality. The letter ratings are provided to indicate the credit worthiness of the underlying bonds in the portfolio and generally range from AAA (highest) to D (lowest). 2 As of 8/31/2015. 3 Negative weights, when quoted, may be due to open security or capital stock trades at period end and/or unrealized loss on derivative positions as a percent of net assets at period end.

The Overall Morningstar Rating for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metrics. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star.

The Barclays Global Aggregate Bond ex-usd (Unhedged) is a broad-based measure of the global investment-grade fixed income markets, excluding U.S. dollar-denominated securities. The three major components of this index are the U.S. Aggregate, the Pan-European Aggregate, and the Asian-Pacific Aggregate Indices. The index also includes Eurodollar and Euro-Yen corporate bonds, Canadian government, agency and corporate securities. Key Terms: Alpha/3yr (annualized) - Shows how a fund did relative to what would have been expected given the fund's Beta and the performance of the benchmark index. For example, an alpha of 1.4 means that the fund outperformed its estimated return (based on market activity alone) by 1.4%. Beta measures the volatility of the fund, as compared to that of the overall market. The market s beta is set at 1.00; a beta higher than 1.00 is considered to be more volatile than the market, while a beta lower than 1.00 is considered to be less volatile. Effective Duration is a weighted average of all bond durations in a fund's portfolio. Duration measures the price sensitivity of a bond or bond fund to changes in interest rates. Specifically, duration represents the approximate percentage change in the price of a bond or bond fund if interest rates move up or down 100 basis points. R2 - (R-squared) is a statistic that indicates how much of a fund s fluctuations were attributable to movements in the fund s benchmark index. Sharpe Ratio measures the potential reward offered by a mutual fund relative to its risk level. Developed by William Sharpe, the ratio uses a fund's standard deviation and its excess return to determine reward per unit of risk. The higher the sharpe ratio, the better the fund's historical risk-adjusted performance. Std. Deviation/3yr (annualized) - Defines how widely returns varied from an average over a given period of time. A higher standard deviation means a more volatile fund. For example, a fund with a standard deviation of 6 and an average annual return of 10% saw annualized monthly returns fall within 6 percentage points of that average (or between 4% and 16%) two-thirds of the time. Weighted Average Life is the average period before the principal of a debt security (bond, debenture, note) is scheduled to be repaid. Fund Facts are provided by FactSet Research Systems, Inc.
