MFS Quarterly Portfolio Commentary Relative to the fund's blended index, US equities was a contributor to overall results. Greater probability that Federal Reserve (Fed) would increase interest rates before the end of the calendar year, and the steady economic expansion supported by consumer spending and a robust labor market helped boost absolute returns during the period. Within this segment, the fund's allocation to the MFS New Discovery Fund (3% allocation), MFS New Discovery Value Fund (3% allocation) and MFS Mid Cap Growth Fund (10% allocation) more than offset relative performance in the MFS Value Fund (13% allocation). The international equity component of the Fund was positive on an absolute basis, however it detracted on a relative basis. European equities were supported by a strong second quarter reporting season driven by economically-sensitive sectors such as information technology, consumer discretionary and materials, while in the UK the sentiment remained strong despite continuous headwinds following the EU referendum Page 1 of 5 NOT FDIC INSURED MAY LOSE VALUE NO BANK GUARANTEE
vote. Within this segment, relative performance in the MFS International Value Fund (8% allocation) and the MFS Research International Fund (8% allocation) detracted from relative performance. Within the fund's specialty asset class exposure, the commodity segment decreased in value during the quarter led by weak energy and agriculture price levels. However, the fund's allocation to the MFS Global Real Estate Fund (5% allocation) offset headwinds of exposure to MFS Commodity Strategy Fund (5% allocation). The fund's allocation to a broad array of underlying funds helped to provide diversification by asset class, investment style, and geographic diversification seeking to dampen volatility and generate enhanced riskadjusted returns for investors during the quarter.
