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 does not reflect the fees and expenses of any Permitted Account. If the fees and expenses of any Permitted Account were reflected, the fees and expenses in the Example would be higher.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and applies whether you hold or redeem all of your shares at the end of each period. The Example also assumes that the expense reimbursement is in place for the first year, that your investment has a 5% return each year, that all dividends and capital gains are reinvested, and that the Fund’s operating expenses are the amount shown in the fee table and remain the same for the years shown. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example - Great-West Large Cap Growth Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Institutional Class	66	208	362	810
Investor Class	102	323	561	1,246
Class L	127	401	695	1,532

Expense Example, No Redemption - Great-West Large Cap Growth Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Institutional Class	66	208	362	810
Investor Class	102	323	561	1,246
Class L	127	401	695	1,532

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 rate may indicate higher transaction costs. 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 turnover rate was 29% of the average value of its portfolio.

Principal Investment Strategies

The Fund will, under normal circumstances, invest 80% of its net assets (plus the amount of any borrowings for investment purposes) in securities selected for their growth potential with market capitalizations of $4 billion or more at the time of purchase. The Fund may invest in foreign securities, which may include investments in emerging markets, without limit within the parameters of the Fund’s specific investment policies. The Fund may also hold cash or other short-term investments. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund’s investment portfolio is managed by two sub-advisers (each, a “Sub-Adviser,” and collectively, the “Sub-Advisers”). The Sub-Advisers seek to invest in securities of issuers with above average potential for growth.

GWCM maintains a strategic asset allocation of the Fund’s assets with each Sub-Adviser and reviews the asset allocations on a quarterly basis, or more frequently as deemed necessary. As of the date of this Prospectus, the target asset allocation is a 50% allocation of the Fund’s assets to each of the Fund’s Sub-Advisers. Notwithstanding the target allocation, GWCM may change the asset allocations at any time and without shareholder notice or approval.

Principal Investment Risks

The following is a summary of the principal investment risks of investing in the Fund:

Currency Risk - Adverse fluctuations in exchange rates between the U.S. Dollar and other currencies may cause the Fund to lose money on investments denominated in foreign currencies.

Derivatives Risk - The Fund may invest in derivative instruments, including but not limited to, futures contracts. Using derivatives can disproportionately increase losses and reduce opportunities for gains when stock prices, currency rates or interest rates are changing. The Fund may not fully benefit from or may lose money on derivatives if changes in their value do not correspond accurately to changes in the value of the Fund’s holdings. The other parties to certain derivative contracts present the same types of credit risk as issuers of fixed income securities. Derivatives can also make a fund less liquid and harder to value, especially in declining markets, and may increase the Fund’s volatility. There can be no assurance that the Fund’s use of derivative contracts will work as intended, and it is possible for the Fund to lose more than its original investment.

Foreign Securities Risk - Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, currency valuation or economic developments. In addition, emerging markets may be more volatile and less liquid than the markets of more mature economies, and the securities of emerging markets issuers often are subject to rapid and large changes in price.

Growth Stock Risk - Growth stocks can be volatile for several reasons. Since they usually reinvest a high proportion of earnings in their own business, they may not pay the dividends usually associated with value stocks that can cushion their decline in a falling market. Also, since investors buy these stocks because of the expected superior earnings growth, earnings disappointments may result in sharp price declines.

Management Risk - A strategy used by the portfolio managers may fail to produce the intended results.

Market Risk - Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market or economic developments in the U.S. and in other countries. Market risk may affect a single company, a sector of the economy, or the market as a whole.

Multi-Manager Risk - Each Sub-Adviser makes investment decisions independently. It is possible that the security selection processes of the Sub-Advisers may not complement one another and the Fund may have buy and sell transactions in the same security on the same day. The Sub-Advisers selected may underperform the market generally or other sub-advisers that could have been selected.

An investment in the Fund is not a deposit with a bank, is not insured, endorsed or guaranteed by the FDIC or any government agency, and is subject to the possible loss of your original investment.

Performance

The bar chart and table below provide an indication of the risk of investment in the Fund by showing changes in the performance of the Fund’s Investor Class shares for the last ten calendar years and by comparing the Fund’s Institutional Class and Investor Class average annual total return to the performance of a broad-based securities market index and a secondary index. No Class L share performance data is provided because Class L shares have not commenced operations. Class L share performance information will appear in future versions of this Prospectus after Class L shares have annual returns for at least one complete calendar year. The returns shown below are historical and are not an indication of future performance. Total return figures assume reinvestment of dividends and capital gains distributions and include the effect of the Fund’s recurring expenses, but do not include fees and expenses of any Permitted Account. If those fees and expenses were reflected, the performance shown would have been lower.

On September 1, 2013, the Fund replaced the prior sub-adviser with the current Sub-Advisers. Consequently, the Fund’s total returns shown below for the periods prior to September 1, 2013 are not necessarily indicative of the performance of the Fund, as it is currently managed.

[1] Other Expenses are estimated for Class L shares because the class has not yet commenced operations.

[2] GWCM has contractually agreed to waive fees or reimburse expenses that exceed 0.65% of the Fund's average daily net assets attributable to each Class, excluding Distribution and Service (12b-1) Fees, Shareholder Services Fees, brokerage expenses, taxes, dividend interest on short sales, interest expenses, and any extraordinary expenses, including litigation costs (the “Expense Limit”). The agreement’s current term ends on April 30, 2019 and automatically renews for one-year terms unless it is terminated by Great-West Funds or GWCM upon written notice within 90 days of the end of the current term or upon termination of the investment advisory agreement. Under the agreement, GWCM may recoup, subject to Board approval, these waivers and reimbursements in future periods, not exceeding three years following the particular waiver/reimbursement, provided Total Annual Fund Operating Expenses of a Class plus such recoupment do not exceed the lesser of the Expense Limit that was in place at the time of the waiver/reimbursement or the Expense Limit in place at the time of recoupment.
