Investment Objective

The Fund seeks high current income and protection of capital through investments in intermediate and long-term U.S. Government debt securities.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. The table and the example below do not reflect the separate account fees charged in the variable annuity or variable life insurance policy ("Variable Contracts") in which the Fund is offered. If separate account fees were shown, the Fund's annual operating expenses would be higher. Please see your Variable Contract prospectus for more details on the separate account fees.

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

Management Fees	0.50%
Other Expenses	0.19%
Total Annual Fund Operating Expenses	0.69%
Fee Waivers and/or Expense Reimbursements1	0.11%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements1	0.58%

discontinued prior to such time only with the approval of the Board of Directors of VALIC Company I ("VC I"), including a majority of the directors who are not "interested persons" of VC I as defined in the Investment Company Act of 1940, as amended.

Expense 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 or hold 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 (except that the Example incorporates any applicable fee waiver and/or expense limitation arrangements for only the first year). The Example does not reflect charges imposed by the Variable Contract. If the Variable Contract fees were reflected, the expenses would be higher. See the Variable Contract prospectus for information on such charges. Although your actual costs may be higher or lower, based on these assumptions and the net expenses shown in the fee table, your costs would be: 

1 Year	3 Years	5 Years	10 Years
$59	$210	$373	$848

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance.

Government Securities Fund

During the most recent fiscal year, the Fund's portfolio turnover rate was 13% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests at least 80% of net assets in intermediate- and long-term U.S. Government and government-sponsored debt securities.

The Fund may also invest in mortgage-backed securities, asset-backed securities, repurchase agreements, high quality corporate debt securities and high quality domestic money market securities. In addition, the Fund may invest up to 20% of its net assets in high quality foreign investments payable in U.S. dollars.

In order to generate additional income, the Fund may lend portfolio securities to broker-dealers and other financial institutions provided that the value of the loaned securities does not exceed 30% of the Fund's total assets. These loans earn income for the Fund and are collateralized by cash and securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities. Investors will be given at least 60 days' written notice in advance of any change to the Fund's 80% investment policy set forth above.

Principal Risks of Investing in the Fund

As with any mutual fund, there can be no assurance that the Fund's investment objective will be met or that the net return on an investment in the Fund will exceed what could have been obtained through other investment or savings vehicles. Shares of the Fund are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation. If the value of the assets of the Fund goes down, you could lose money.

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

U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the "full faith and credit" of the U.S. Government and are generally considered to have low credit risk. Unlike U.S. Treasury obligations, securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government and are therefore subject to greater credit risk than securities issued or guaranteed by the U.S. Treasury.

Credit Risk. The Fund may suffer losses if the issuer of a fixed income security owned by the Fund is unable to make interest or principal payments.

Interest Rate Risk. The value of fixed-income securities may decline when interest rates go up or increase when interest rates go down. The interest earned on fixed-income securities may decline when interest rates go down or increase when interest rates go up. Longer-term and lower coupon bonds tend to be more sensitive to changes in interest rates. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to these initiatives.

Call or Prepayment Risk. During periods of falling interest rates, a bond issuer may "call" a bond to repay it before its maturity date. The Fund may only be able to invest the bond's proceeds at lower interest rates, resulting in a decline in the Fund's income.

Currency Risk. Because the Fund's foreign investments are generally held in foreign currencies, the Fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar. Such gains or losses may be substantial.

Foreign Investment Risk. Investment in foreign securities involves risks due to several factors, such as illiquidity, the lack of public information, changes in the exchange rates between foreign currencies and the U.S. dollar, unfavorable political, social and legal developments, or economic and financial instability. Foreign companies are not subject to the U.S. accounting and financial reporting standards and may have riskier settlement procedures. U.S. investments that are denominated in foreign currencies or that are traded in foreign markets, or securities of U.S. companies that have significant foreign operations may be subject to foreign investment risk.

Market Risk. The Fund's share price can fall because of weakness in the broad market, a particular industry, or specific holdings or due to adverse social, political or economic developments here or abroad, changes in investor psychology, technological disruptions, or heavy institutional selling and other conditions or events (including, for example, military confrontations, war, terrorism, trade wars, disease/virus outbreaks and epidemics). The prices of individual securities may fluctuate, sometimes dramatically, from day to day. The prices of stocks and other equity securities tend to be more volatile than those of fixed-income securities.

Mortgage-Backed Securities Risk. Mortgage-backed securities are similar to other debt securities in that they are subject to credit risk and interest rate risk. Mortgage-backed securities may be issued or guaranteed by the

Government Securities Fund

U.S. Government, its agencies or instrumentalities or may be non-guaranteed securities issued by private issuers. These securities are also subject to the risk that issuers will prepay the principal more quickly or more slowly than expected, which could cause the Fund to invest the proceeds in less attractive investments or increase the volatility of their prices.

Asset-Backed Securities Risk. Asset-backed securities are bonds or notes that are normally supported by a specific property. If the issuer fails to pay the interest or return the principal when the bond matures, then the issuer must give the property to the bondholders or noteholders. Examples of assets supporting asset-backed securities include credit card receivables, retail installment loans, home equity loans, auto loans, and manufactured housing loans.

Securities Lending Risk. Engaging in securities lending could increase the market and credit risk for Fund investments. The Fund may lose money if it does not recover borrowed securities, the value of the collateral falls, or the value of investments made with cash collateral declines. The Fund's loans will be collateralized by securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities, which subjects the Fund to the credit risk of the U.S. Government or the issuing federal agency or instrumentality. If the value of either the cash collateral or the Fund's investments of the cash collateral falls below the amount owed to a borrower, the Fund also may incur losses that exceed the amount it earned on lending the security. Securities lending also involves the risks of delay in receiving additional collateral or possible loss of rights in the collateral if the borrower fails. Another risk of securities lending is the risk that the loaned portfolio securities may not be available to the Fund on a timely basis and the Fund may therefore lose the opportunity to sell the securities at a desirable price.

Money Market Securities Risk. An investment in the Fund is subject to the risk that the value of its investments in high-quality short-term obligations ("money market securities") may be subject to changes in interest rates, changes in the rating of any money market security and in the ability of an issuer to make payments of interest and principal.

Repurchase Agreements Risk. Repurchase agreements are agreements in which the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon price and date. Repurchase agreements carry the risk that the counterparty may not fulfill its obligations under the agreement. This could cause the Fund's income and the value of the Fund to decline.

Performance Information

The following Risk/Return Bar Chart and Table illustrate the risks of investing in the Fund by showing changes in the Fund's performance from calendar year to calendar year and comparing the Fund's average annual returns to those of the Bloomberg U.S. Aggregate Bond Index (a broad-based securities market index) and the Bloomberg U.S. Government Bond Index, which is relevant to the Fund because it has characteristics similar to the Fund's investment strategies. Fees and expenses incurred at the contract level are not reflected in the bar chart or table. If these amounts were reflected, returns would be less than those shown. Of course, past performance of the Fund is not necessarily an indication of how the Fund will perform in the future.

Effective, August 5, 2013, J.P. Morgan Investment Management Inc. ("JPMIM") assumed management of the Fund. Prior to this time, the Fund was co-sub-advised by JPMIM and SunAmerica Asset Management, LLC ("SunAmerica").

Purchases and Sales of Fund Shares

Shares of the Funds may only be purchased or redeemed through Variable Contracts offered by the separate

accounts of VALIC or other participating life insurance companies and through qualifying retirement plans ("Plans") and IRAs. Shares of each Fund may be purchased and redeemed each day the New York Stock Exchange is open, at the Fund's net asset value determined after receipt of a request in good order.

The Funds do not have any initial or subsequent investment minimums. However, your insurance company may impose investment or account value minimums. The prospectus (or other offering document) for your Variable Contract contains additional information about purchases and redemptions of the Funds' shares.

Tax Information

A Fund will not be subject to U.S. federal income tax so long as it qualifies as a regulated investment company and distributes its income and gains each year to its shareholders. However, contractholders may be subject to federal income tax (and a federal Medicare tax of 3.8% that applies to net income, including taxable annuity payments, if applicable) upon withdrawal from a Variable Contract. Contractholders should consult the prospectus (or other offering document) for the Variable Contract for additional information regarding taxation.

Payments to Broker-Dealers and
Other Financial Intermediaries

The Funds are not sold directly to the general public but instead are offered to registered and unregistered separate accounts of VALIC and its affiliates and to Plans and IRAs. The Funds and their related companies may make payments to the sponsoring insurance company or its affiliates for recordkeeping and distribution. These payments may create a conflict of interest as they may be a factor that the insurance company considers in including the Funds as underlying investment options in a variable contract. Visit your sponsoring insurance company's website for more information.
