The Matrix Advisors Value Fund (the "Fund") seeks to achieve a total rate of

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund.

Portfolio Turnoverrr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Fund
shares are held in a taxable account. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover
rate was 25% of the average value of its portfolio.

Expense Example, Headingrr_ExpenseExampleHeadingExample
Expense Example, Narrativerr_ExpenseExampleNarrativeTextBlock
This Example is intended to help you compare the costs of investing in the Fund
with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same.

Investment Strategy, Headingrr_StrategyHeadingPrincipal Investment Strategies
Investment Strategy, Narrativerr_StrategyNarrativeTextBlock
The Fund invests primarily in both dividend and non-dividend paying common
stocks of domestic companies that the Advisor believes are financially strong
and meet specific valuation criteria using the principles of value investing
based on Classic Valuation Analysis. Using valuation models, statistics such as
earnings growth, dividend growth, return on equity and book value are analyzed
versus their historical, current and projected levels to determine a company's
"Fair Value." The Fund invests primarily in large capitalization companies,
which the Advisor defines as companies with minimum market capitalizations of
$2 billion at the time of purchase. Stocks will be sold when the Advisor
believes they no longer represent value. The Fund may invest in any sector. At
times it may overweight one or more particular sectors, and/or underweight or
even abstain from one or more particular sectors.
Risk, Headingrr_RiskHeadingPrincipal Investment Risks
Risk, Narrativerr_RiskNarrativeTextBlock
There is a risk that you could lose all or a portion of your investment in the
Fund. The following are some of the principal risks that can affect the value of
your investment:

o  Management Risk: The risk that the Advisor may fail to implement the Fund's
   investment strategies and meet its investment objective.

o  Market Risk: The market price of a security may fluctuate, sometimes rapidly
   and unpredictably. These fluctuations may cause a security to be worth less
   than its cost when originally purchased or less than it was worth at an
   earlier time.

o  Common Stock Risk: Common stocks are susceptible to general stock market
   fluctuations and to volatile increases and decreases in value.

o  Sector Emphasis Risk: Investing a substantial portion of the Fund's assets in
   related industries or sectors may have greater risks because companies in
   these sectors may share common characteristics and may react similarly to
   market developments.

o  Value Strategy Risk: The stock of value companies can continue to be
   undervalued for long periods of time and not realize its expected value. The
   value of the Fund may decrease in response to the activities and financial
   prospects of an individual company.
Risk, Lose Moneyrr_RiskLoseMoneyThere is a risk that you could lose all or a portion of your investment in the Fund.

After tax returns are calculated using the historically highest individual
federal marginal income tax rates and do not reflect the impact of state and
local taxes. Actual after-tax returns depend on an investor's tax situation and
may differ from those shown, and after-tax returns shown are not relevant to
investors who hold their Fund shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In certain cases, the figure
representing "Return after taxes on distributions and sale of fund shares" may
be higher than the other return figures for the same period. A higher after-tax
return results when a capital loss occurs upon redemption and provides an
assumed tax deduction that benefits the investor.

[1]The Total Annual Fund Operating Expenses has been restated to reflect the reduction of the Management Fees from 1.00% to 0.75% effective September 1, 2010. Accordingly, the figure does not correlate to the Ratio of Operating Expenses to Average Net Assets Before Expense Reimbursement provided in the "Financial Highlights" section of the statutory prospectus.
[2]Matrix Asset Advisors, Inc. (the "Advisor"), the Fund's investment adviser, has contractually agreed to reduce its fees and/or pay Fund expenses (excluding acquired fund fees and expenses, leverage interest, taxes, brokerage commissions and extraordinary expenses) in order to limit the Fund's total annual fund operating expenses to 0.99% of the Fund's average net assets (the "Expense Cap"). The Expense Cap will remain in effect until at least October 31, 2012. The agreement may be terminated at any time, and without payment of any penalty, by the Fund's Board of Directors (the "Board of Directors") upon 60 days' written notice to the Advisor. The agreement may not be terminated by the Advisor without the consent of the Board of Directors. The Advisor is permitted, with Board approval, to be reimbursed for fee reductions and/or expense payments made in the prior three years. This reimbursement may be requested if the aggregate amount actually paid by the Fund toward operating expenses for the fiscal year (taking into account the reimbursement) does not exceed the Expense Cap. Currently, the Advisor has agreed not to seek reimbursement of such fee reductions and/or expense payments.
