Past performance does not guarantee future results. Performance cited represents past performance and current performance may be higher or lower than the
data quoted. Gross investment performance assumes reinvestment of dividends and capital gains, is gross of investment management fees and net of transaction costs.
Attribution by segment is based on estimated returns of equities held within the segments listed. All stocks held during a measurement period, including purchases and sales,
are included. Cash is not allocated among segments. Calculations are for attribution analysis only and are not intended to represent simulated performance history. The
actual returns may be higher or lower. We calculate attribution using our proprietary attribution system. Our proprietary attribution system runs transactions-based
attribution, taking into account all trading activity. Interaction effect is reallocated into Selection effect. Sectors are based on Global Industry Classification (GICS) Sectors.
International investing involves special risk considerations, including currency fluctuations, lower liquidity, economic and political risk.

1 Month EPS Revision Breadth: 1-month factor representing the trend in the direction of estimate changes. Range from -100% to +100%, it is calculated
as the number of positive revisions minus the number of negative revisions divided by the total number of estimates.

Active Share: A measure of the percentage of equity holdings in a portfolio that differ from the benchmark index. It is calculated by taking the sum of the
absolute value of the differences of the weight of each holding in a portfolio versus the weight of each holding in the index and dividing by two.

Alpha: A measure of a portfolio’s return in excess of the market return, after both have been adjusted for risk. It is a mathematical estimate of the amount
of return expected from a portfolio above and beyond the market return at any point in time. For example, an alpha of 1.25 indicates that a stock is
projected to rise 1.25% in price in a year over the return of the market, or the return when the market return is zero. When an investment price is low
relative to its alpha, it is undervalued, and considered a good selection.

Beta: A quantitative measure of the volatility of the portfolio relative to the overall market, represented by a comparable benchmark. A beta above 1 is
more volatile than the overall market, while a beta below 1 is less volatile, and could be expected to rise and fall more slowly than the market.

Cash Flow Return on Invested Capital (ROIC): A measure of how effectively a company generates cash flow based on legacy capital investment.

Developed Markets: Using the Morgan Stanley Capital International (MSCI) geographic definition, this region includes: United Kingdom, Europe (Austria,
Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Spain, Sweden and Switzerland), Japan, Pacific Asia (Australia,
Hong Kong, New Zealand, and Singapore) and the Western Hemisphere (Canada and other Americas).

Debt to Total Capital Ratio: This figure is the percentage of each company’s invested capital that consists of debt. Companies with a high Debt to Total
Capital level may be considered more risky. From a portfolio perspective, the portfolio Debt to Total Capital Ratio is a weighted average of the individual
holdings' Debt to Total Capital Ratio.

Emerging Markets: Using MSCI’s geographic definition, this region includes: Emerging Markets Asia (China, India, Indonesia, Malaysia, S Korea, Taiwan,
and Thailand), Emerging Markets Europe, Mid-East and Africa (Czech Republic, Hungary, Poland, Russia, Turkey, Egypt, Morocco, and S Africa), and Latin
America (Argentina, Brazil, Chile, Columbia, Mexico, Peru and Venezuela).

EPS (Earnings Per Share) Growth Rate (Projected): This measure represents the weighted average of forecasted growth in earnings expected to be
experienced by the stocks within the portfolio over the next 3-5 years. From a portfolio perspective, the portfolio P/E ratio and EPS Growth Rate are
weighted averages of the individual holdings’ P/E ratios and EPS Growth Rates. Data calculated in FactSet.

EPS Growth Rate - 5-Year Historic: The weighted average earnings per share growth for stock within the portfolio over the past 5 years.

EV/EBITDA: (Enterprise Value / Earnings Before Interest, Taxes and Depreciation-Amortization): The EV/EBITDA ratio is useful for global
comparisons because it ignores the distorting effects of individual countries' taxation policies. It's used to find attractive takeover candidates. Enterprise
value is a better measure than market cap for takeovers because it takes into account the debt which the acquirer will have to assume. Therefore, a
company with a low EV/EBITDA ratio can be viewed as a good takeover candidate.

EV/IC: (Enterprise Value / Invested Capital) Ratio: Enterprise Value (EV), which is market capitalization minus cash plus debt divided by Invested
Capital (IC), which is the sum of common stock, preferred stock and long-term debt. This number will get you a simple multiple. If it is below 1.0, then it
means that the company is selling below book value and theoretically below its liquidation value.

Information Coefficient: A measure of the correlation between expected and actual returns.

Information Ratio: A measure of risk-adjusted return. The annualized excess return of the portfolio relative to a respective benchmark, divided by the
annualized tracking error relative to that same benchmark. The higher the measure, the higher the risk-adjusted return.

PBV: (Price/Book Value) Ratio: The PBV Ratio measures the value of a company's common stock relative to its shareholder's equity. A price-to-book
multiple above one means that the price of the company's common stock is higher than its common shareholder's equity. A price-to-book multiple below
one means that the price of the company's common stock are less than its break-up value, and the shares may be undervalued.

PCF: (Price/CashFlow): Some analysts favor the price/cash flow over the price-earnings (PE) ratio as a measure of a company’s value. Cash flow is a
measure of a company's financial health. It equals cash receipts minus cash payments over a given period of time.

P/E: (Price/Earnings) Ratio: This is the most common measure of how expensive a stock is. Simply, it is the cost an investor in a given stock must pay
per dollar of current annual earnings. A high P/E generally indicates that the market is paying more to obtain the stock because it has confidence in the
company’s ability to increase its earnings. Conversely, a low P/E often indicates that the market has less confidence that the company’s earnings will
increase rapidly or steadily, and therefore will not pay as much for its stock.

R-squared: A measurement of how closely the portfolio’s performance correlates with the performance of its benchmark, such as the MSC AC World Free
ex US Index. In other words, it is a measurement of what portion of a portfolio’s performance can be explained by the performance of the overall market or
index. Ranges from 0 to 1, where 0 indicates no correlation and 1 indicates perfect correlation.

Risk (Standard Deviation): A measure of the portfolio’s risk. A higher standard deviation represents a greater dispersion of returns, and thus a greater
amount of risk. The annualized standard deviation is calculated using monthly returns.

Sharpe-Ratio: A risk-adjusted measure calculated using standard deviation and excess return (Portfolio return – Risk Free Rate) to determine reward per
unit of risk. The higher the Sharpe ratio, the better the portfolio’s historic risk-adjusted performance.

Tracking Error: Tracking Error measures the extent to which a portfolio tracks its benchmark. The tracking error of an index portfolio should be lower
than that of an active portfolio. The tracking error will always be greater than zero if the portfolio is anything other than a replication of the benchmark.

Trailing 1-Year Turnover: This figure reflects the portfolio’s trading activity by calculating the amount of the portfolio’s holdings bought or sold over the
prior year, expressed as a percentage of the portfolio’s average market value. Turnover figures may be related to the amount of trading costs experienced
by the portfolio.

Weighted Average Market Capitalization: Market capitalization refers to the total market value of each company's outstanding shares. The Weighted
Average Market Capitalization for a portfolio is calculated as the average market capitalization of the stocks within the portfolio, weighted by the amount of
each stock owned.

Weighted Median Market Capitalization: This calculation represents the median market capitalization of the stocks in the portfolio, weighted by the
amount of each stock owned.
