Penn Series Developed International Index Fund

FUND SUMMARY:  DEVELOPED INTERNATIONAL INDEX FUND

Investment Objective

The investment objective of the Developed International Index Fund (the “Fund”) is to seek to replicate the returns and characteristics of an international index composed of securities from developed countries.

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Additional fees and expenses will be applied at the variable contract level. Those fees and expenses are described in your variable contract prospectus. If the information below were to reflect the deduction of variable contract charges, fees and expenses would be higher.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost 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. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
Penn Series Developed International Index Fund Developed International Index Fund	84	262	455	1,014

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in the 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 7% of the average value of its portfolio.

Principal Investment Strategy

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities listed in the MSCI^® Europe, Australasia, Far East (MSCI EAFE) Index (the "Index"). Under normal circumstances, however, the Fund intends to invest substantially all of its assets in securities of companies included in the Index (including ADRs and Global Depositary Receipts ("GDRs")) and close substitutes (such as index futures contracts) that are designed to track the Index. The Index is an arithmetic, market value-weighted average of the performance of approximately 1,000 securities primarily from Europe, Australia, Asia and the Far East. The Fund may concentrate (invest 25% or more of the value of its assets) in the securities of issuers having their principal business activities in the same industry if the Index is also concentrated in such industry.

The Sub-Adviser does not manage the Fund according to traditional methods of "active" investment management, which involve the buying and selling of securities based upon economic, financial and market analysis and investment judgment. Instead, the Sub-Adviser utilizes a "passive" investment approach, attempting to replicate the investment performance of its benchmark Index through automated statistical analytic procedures.

The Sub-Adviser seeks to replicate the returns of the Index by investing in the securities of the Index in approximately their Index weight. However, under various circumstances, it may not be possible or practicable to purchase all of those securities in those weightings. In those circumstances, the Fund may purchase a sample of stocks in the Index in proportions expected to replicate generally the performance of the Index as a whole. In addition, from time to time, stocks are added to or removed from the Index. The Fund may sell stocks that are represented in the Index, or purchase stocks that are not yet represented in the Index, in anticipation of their removal from or addition to the Index.

The Sub-Adviser may at times purchase or sell futures contracts in lieu of investment directly in the stocks making up the Index. The Sub-Adviser might do so, for example, in order to increase the Fund's investment exposure pending investment of cash in the stocks comprising the Index. Alternatively, the Sub-Adviser might use futures to reduce its investment exposure to the Index in situations where it intends to sell a portion of the stocks in the Fund's portfolio but the sale has not yet been completed. The Sub-Adviser may also enter into forward foreign currency exchange contracts in an attempt to match the Index's currency exposures.

Principal Risks of Investing

Concentration Risk.  The possibility that, to the extent the Fund invests to a significant extent in a particular industry or group of industries within a particular sector, the Fund may be subject to greater risks than if its investments were broadly diversified across industries and sectors. The Fund also is subject to loss due to adverse occurrences that may affect that industry or group of industries.

Currency Risk.  The possibility that the value of the Fund’s assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and restrictions or prohibitions on the repatriation of foreign currencies.

Depositary Receipt Risk.  The possibility that the Fund’s investments in foreign companies through depositary receipts will expose the Fund to the same risks as direct investment in securities of foreign issuers. In addition, investments in ADRs and GDRs may be less liquid than the underlying shares in their primary trading market, and the value of securities underlying ADRs and GDRs may change materially at times when U.S. markets are not open for trading.

Derivatives Risk.  The possibility that the Fund’s use of derivatives, such as futures, options and swap agreements, may lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than mitigate risk. Certain derivative instruments may be difficult to sell when the Sub-Adviser believes it would be appropriate to do so, difficult to value if the instrument becomes illiquid, or the other party to a derivative contract may be unwilling or unable to fulfill its contractual obligations.

Foreign Investment Risk.  The possibility that the Fund’s investments in foreign securities may be adversely affected by political, social, and economic conditions affecting foreign issuers, greater volatility, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar.

Investment Style Risk.  The possibility that the Fund could underperform if the Fund’s investment style shifts out of favor based on changing market sentiment and conditions.

Liquidity Risk.  The possibility that the market for certain of the Fund’s investments may become illiquid under adverse or volatile market or economic conditions, making those investments difficult to sell at an advantageous price. The market price of certain investments may fall dramatically if there is no liquid trading market for the investments. It also may be difficult for the Fund to purchase a desired investment at an advantageous price under such circumstances.

Market Risk.  The possibility that the values of, and/or the income generated by, securities held by the Fund may decline, sometimes unpredictably, due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Passive Investment Risk.  The possibility that the Fund’s return may be lower than the return of an actively managed fund because the Fund holds shares of a security based on the holdings of its benchmark index, not the current or projected performance of a security, industry or sector. The Fund does not take defensive positions under any market conditions, including declining markets.

Sampling Risk.  The possibility that the Fund may not hold all of the securities included in its benchmark index and that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund’s benchmark index.

Tracking Error Risk.  The possibility that the Fund’s performance may deviate from that of the benchmark index it seeks to track. This risk may be heightened during times of increased market volatility or other unusual market conditions.

An investment in the Fund may be appropriate for investors who are willing to accept the risks and uncertainties of investing in international securities in the hope of achieving returns similar to that of the Index.

Performance Information

The bar chart and table below show the performance of the Fund both year-by-year and as an average over different periods of time. The bar chart and table demonstrate the variability of performance over time and provide an indication of the risks and volatility of an investment in the Fund by showing how the Fund’s average annual total returns for various periods compare with those of a broad-based securities market index. Past performance does not necessarily indicate how the Fund will perform in the future. This performance information does not include the impact of any charges deducted under your variable contract. If it did, returns would be lower.
