Past performance does not guarantee future results.

Rates of return for periods greater than one year are annualized. The information given for this composite is historic and should not be taken as an indication of future performance. Performance returns are presented both before and after the deduction of advisory fees. Portfolio returns are calculated using a time-weighted return method. Portfolio returns reflect the reinvestment of dividends and other income and the deduction of brokerage fees, other commissions if any, and foreign withholding taxes. For the period 10/1/2012-12/31/2015, gross and net portfolio returns reflect the deduction of custodial, administrative, audit, legal, operating, and other expenses. Composite returns are calculated monthly by weighting portfolio returns by the beginning market value. Net return calculation:
A. For the period 7/1/2006-3/31/2014, composite net returns reflect the monthly deduction of an annual model advisory fee of 1.00%:

A1. For the period 7/1/2006-9/30/2012, one or more accounts paid a fee higher than the 1.00% model fee. During this period, the composite net return using the model fee of 1.00% was 10.95%. The composite net return using actual fees paid was 10.61%.
A2. For the period 10/1/2012-3/31/2014, no account in the composite paid a fee higher than the 1.00% model fee.

B. For the period 4/1/2014-12/31/2019, the composite net return is calculated using actual advisory fees with the following exception: one member of the composite was a mutual fund portfolio whose fee was partially waived due to an expense limitation agreement. The composite net return shown during this period does not reflect this waiver and is therefore lower than the actual return.
C. From 1/1/2020 onward, the composite net return is calculated using actual advisory fees, including any applicable mutual fund fee waivers.
D. Our fees may vary between accounts due to portfolio size, client type, or other factors.

Performance for the periods 7/1/2006-9/30/2012 and 10/1/2012-3/31/2016 represents the results of portfolios managed by the investment team while at RS Investment Management Co. LLC and Callinan Asset Management LLC, respectively, and employing the same investment strategy being used at OCM.

The Small Cap Growth Composite includes all fee-paying separately managed accounts, limited partnerships, and mutual funds that are predominantly invested in a concentrated selection of the equity securities of small and medium capitalization companies that can rapidly grow revenues and earnings. Portfolios normally remain primarily invested in equity securities except in times of unusual market stress when a more defensive allocation may be deemed prudent. The non-equity portion may be invested in holdings such as cash, cash equivalents, short-term debt securities, mutual funds, and ETFs. The benchmark is the Russell 2000® Growth Index.

Past performance does not guarantee future results.

Rates of return for periods greater than one year are annualized. The information given for these composites is historic and should not be taken as an indication of future performance. Performance returns are presented both before and after the deduction of advisory fees. Account returns are calculated using a time-weighted return method. Account returns reflect the reinvestment of dividends and other income and the deduction of brokerage fees and other commissions, if any, but do not reflect the deduction of certain other expenses such as custodial fees. Monthly composite returns are calculated by weighting account returns by beginning market value. Net returns reflect the deduction of actual advisory fees, which may vary between accounts due to portfolio size, client type, or other factors. From 1/1/2021 onward, net returns also reflect mutual fund fee waivers in certain periods.

The S&P 500 Index is widely regarded as the standard for measuring large cap U.S. stock market performance. The index does not incur expenses, is not available for investment, and includes the reinvestment of dividends. The S&P 500 Index data are provided for comparison of the composite’s performance to the performance of the stock market in general. The S&P 500 Index performance is not, however, directly comparable to the composites’ performance because accounts in the composites generally invest by using a portfolio of 30-40 stocks and the S&P 500 Index is an unmanaged index that is widely regarded as the standard for measuring U.S. stock market performance.

The fee schedule is as follows: 1.25% on the first $10 million, 1.00% on the next $15 million up to $25 million, and 0.75% in excess of $25 million. A discounted, institutional rate is available.

Clients invested in separately managed core equity accounts are subject to various risks including potential loss of principal, general market risk, small and medium-sized company risk, foreign securities and emerging markets risk and default risk. For a complete discussion of the risks involved, please see our Form ADV Brochure and refer to Item 8.

The Core Equity Composite includes all fee-paying separately managed accounts that are predominantly invested in equity securities, and for which OCM has the discretion to increase and decrease equity exposure in an effort to reduce risk. The non-equity portion of the account may be invested in cash equivalents, fixed income securities, or mutual funds. Individual account performance will vary from the composite performance due to differences in individual holdings, cash flows, etc.
