Fees and Expenses

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The Fund is offered exclusively as an investment option for certain Contracts.  The table below reflects only Fund expenses and does not reflect Contract fees and expenses.  Please refer to the Contract prospectus for a description of those fees and expenses.

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

Annual Fund Operating Expenses		AZL Mid Cap Index Fund
Management Fee		0.25%
Distribution (12b-1) Fees		0.25%
Recoupment	[1]	0.01%
Other Operating Expense		0.09%
Acquired Fund Fees and Expenses	[2]	0.02%
Total Annual Fund Operating Expenses		0.62%

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. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that you reinvest all dividends and distributions. It does not reflect any Contract fees. If Contract fees were included, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
AZL Mid Cap Index Fund	63	199	346	774

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 portfolio turnover rate was 9% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund employs a passive management approach, investing in a portfolio of assets whose performance is expected to match approximately the performance of the S&P 400 Index before the deduction of Fund expenses. Under normal circumstances, the Fund invests at least 80% of the value of its net assets in a statistically selected sampling of equity securities of companies included in the S&P 400 Index and in derivative instruments linked to the S&P 400 Index, primarily futures contracts.

The S&P 400 Index is a market-weighted index composed of approximately 400 common stocks of medium-sized U.S. companies in a wide range of businesses chosen by Standard & Poor's based on a number of factors, including industry representation, market value, economic sector and operating/financial condition. As of December 31, 2012, the market capitalizations of companies in the S&P 400 Index ranged from $273 million to $12.7 billion.

The Fund does not necessarily invest in all of the securities in the S&P 400 Index or in the same weightings as the securities have in the index. The Fund's subadviser chooses investments so that the market capitalizations, industry weightings, and other fundamental characteristics of the securities chosen are similar to the S&P 400 Index as a whole.

Principal Risks of Investing in the Fund

The price per share of the Fund will fluctuate with changes in the value of the investments held by the Fund. You may lose money by investing in the Fund. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. There is no guarantee that the Fund will achieve its objective.

The following is a summary of the principal risks to which the Fund’s portfolio as a whole is subject.  As changes occur in a Fund’s portfolio holdings, the extent to which the portfolio is subject to each of these risks may also change.

• Market Risk  The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably.

• Issuer Risk  The value of a security may decline for a number of reasons directly related to the issuer of the security.

• Capitalization Risk Investing in small to midsized companies creates risk because smaller companies may have unpredictable or limited earnings, and their securities may be less liquid or experience more volatile prices than those of large companies.

• Index Fund Risk  The Fund does not attempt to manage market volatility or reduce the effects of poor stock performance.  In addition, factors such as Fund expenses, selection of a representative portfolio, changes in the composition of the index, or the timing of purchases or redemptions of Fund shares may affect the correlation between the performance of the index and the Fund’s performance.

• Derivatives Risk  Investing in derivative instruments involves risks that may be different from or greater than the risks associated with investing directly in securities or other traditional investments.

Performance Information

The following bar chart and table provide an indication of the risks of an investment in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns for one year and since its inception compare with those of a broad measure of market performance.

Both the bar chart and the table assume reinvestment of dividends and distributions.

The performance of the Fund will vary from year to year. The Fund’s performance does not reflect the cost of insurance and separate account charges which are imposed under your variable annuity contract or variable life insurance policy. If they were included, performance would be reduced. Past performance does not indicate how the Fund will perform in the future.

[1] The Manager and the Fund have entered into a written contract limiting operating expenses, excluding certain expenses (such as interest expense and Acquired Fund Fees and Expenses), to 0.71% through April 30, 2014. After April 30, 2014, the Manager may terminate the contract for any reason on 30 days written notice to the Fund. Amounts contractually waived or reimbursed in a particular fiscal year may be recouped by the Manager.
