ANALYSIS By Atlanta Capital Management Company, LLC (Sub-Advisor)

Although the Portfolio produced a strong absolute gain for the first quarter, some headwinds held back its relative results. First, value stocks substantially outperformed growth stocks this quarter, which did not benefit this growth-oriented strategy.

Second, low-quality stocks performed far better than high-quality ones. We spent the last 12 months raising the average quality level of the Portfolio’s holdings because we believe those stocks offer significant long-term value, but that position certainly hurt relative performance in the first quarter.

The Portfolio’s overweight to the Information Technology sector was a drag on performance during the quarter. Otherwise, stock selection accounted for most of the relative underperformance for the period. Solid contributions in the Financials, Health Care, and Materials sectors could not overcome drags from the two Consumer sectors and, in particular, Energy. On the positive side of the ledger, the Portfolio benefited most from strong returns by Cameron International, IntercontinentalExchange, Gilead Sciences, B/E Aerospace, and Texas Instruments. Stronger-than-expected orders or financial results were a common thread among these stocks. Additionally, Intercontinental Exchange’s 32% return for the quarter was helped along by improved synergy from its acquisition of NYSE Euronext.

These and other successes were not enough to generate positive stock selection for the quarter. While numerous holdings lagged the benchmark, there were no big detractors in the quarter, and only five individual holdings actually declined. Apple was the worst performer in absolute terms, although it was not a top relative performance detractor. The company has been dealing with a product transition but in our view has suffered more from improved competitiveness from Samsung than from its own choices. We believe that Apple’s valuation has become compelling enough to create a substantial opportunity for outperformance in coming quarters.

Other detractors included Suncor Energy and Edwards Lifesciences. Suncor has been a major disappointment. Although its valuation looks very low compared with other Energy stocks, its management execution has been spotty. Meanwhile, Edwards is early in the launch cycle of a catheter-delivered heart valve and sales growth was a bit slower than expected. That should improve in the months ahead.

The Portfolio’s negative stock selection in the two Consumer sectors was mostly about not owning any media stocks in Consumer Discretionary or food stocks in Consumer Staples (where the leveraged buyout of H.J. Heinz drove all food stocks higher). Within the Energy sector, the Portfolio did not include refiners, which soared 30% to 50% for the period. In all three of these cases, we didn’t see either the quality or growth characteristics necessary for inclusion in the Portfolio’s universe.

Current and future portfolio holdings are subject to market risk.

Investment in mutual funds involves risk, including possible loss of principal invested. You could lose money on your investment in the Fund or the Fund could underperform because of the following risks: the market prices of stocks held by the Fund may fall; individual investments of the Fund may not perform as expected; and/or the Fund’s portfolio management practices may not achieve the desired result. In addition, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies, especially during periods of economic expansion.
