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. If Contract fees and expenses were included, the fees and expenses in the following table would be higher. Please refer to the Contract prospectus for a description of those fees and expenses.

Portfolio Turnover [Text Block] rr_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. 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 21% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

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. It reflects the management fee waiver agreement for the first year. 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:

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To achieve the Fund’s investment objective, the Subadviser implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Fund’s design emphasizes long-term drivers of expected returns identified by the Subadviser’s research, while balancing risk through broad diversification across companies and sectors. The Subadviser’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.

 

The Fund is designed to purchase a broad and diverse group of equity securities of non-U.S. companies in developed markets. The Fund invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price and higher profitability companies as compared to their representation in the International Universe. For purposes of this Fund, the Subadviser defines the International Universe as a market capitalization weighted set (e.g., the larger the company, the greater the proportion of the International Universe it represents) of non-U.S. companies in developed markets that have been authorized as approved markets for investment by the Subadviser’s Investment Committee. The Fund’s increased exposure to smaller capitalization, lower relative price and higher profitability companies may be

 

achieved by decreasing the allocation of the Fund’s assets to larger capitalization, higher relative price or lower profitability companies relative to their weight in the International Universe. An equity issuer is considered to have a high relative price (i.e., a growth stock) primarily because it has a high price in relation to its book value. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Subadviser may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Subadviser uses for assessing relative price and profitability are subject to change from time to time.

 

The Fund intends to purchase securities of companies associated with developed market countries that the Subadviser has designated as approved markets. As a non-fundamental policy, under normal circumstances, the Fund will invest at least 80% of its net assets in equity securities. The Subadviser determines company size on a country or region specific basis and based primarily on market capitalization. The percentage allocation of the assets of the Fund to securities of the largest high relative price companies will generally be reduced from between 5% and 35% of their percentage weight in the International Universe. The percentage by which the Fund’s allocation to securities of the largest high relative price companies is reduced will change due to market movements and other factors.

 

The Subadviser may also increase or reduce the Fund’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals and investment characteristics. In assessing a company’s investment characteristics, the Subadviser considers ratios such as recent changes in assets divided by total assets. The criteria the Subadviser uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Subadviser seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

 

The Fund may gain exposure to companies associated with approved markets by purchasing equity securities in the form of depositary receipts, which may be listed or traded outside the issuer’s domicile country. The Fund also may purchase or sell futures contracts and options on futures contracts for foreign or U.S. equity securities and indices, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Fund.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

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, five years, and since its inception compare with those of a broad-based measure of market performance, the MSCI EAFE Index (gross div). The Fund’s performance also is compared to the returns of the MSCI World ex-USA Index (gross div), which is relevant to the Fund because it has characteristics similar to the Fund’s investment strategies.

 

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 Contract. If they were included, performance would be reduced. Past performance does not indicate how the Fund will perform in the future.

Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Market Risk – The market value of portfolio securities may go up or down, sometimes rapidly and unpredictably. The value of a security or other asset may fluctuate significantly due to factors such as changes in general market conditions, including economic, political, and financial conditions, widespread disease or other public health issues, war, military conflict, acts of terrorism, adverse investor sentiment, or instability or other disruptive events in the local, regional or global markets. Certain changes in the U.S. economy, such as a decrease in imports or exports, changes in trade regulations, inflation and/or economic recession, may have an adverse effect on the value of the Fund’s securities.
AZL DFA International Core Equity Fund | Issuer Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Issuer Risk – The value of a security may decline for a number of reasons directly related to the issuer of the security. Further, the value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.
AZL DFA International Core Equity Fund | Selection Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Selection Risk – Because this Fund is actively managed, there can be no guarantee that investment decisions made for the Fund will produce the desired results.
AZL DFA International Core Equity Fund | Profitability Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Profitability Investment Risk – High relative profitability stocks may perform differently from the market as a whole and following a profitability-oriented strategy may cause a Fund to, at times, underperform equity funds that use other investment strategies.
AZL DFA International Core Equity Fund | Value Stocks Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Value Stocks Risk – Value stocks may perform differently from the market as a whole and following a value-oriented investment strategy may cause the Fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry developments than the market as a whole and other types of stocks. If the market does not recognize that a selected security is undervalued, the prices of that security might not appreciate as anticipated. Value stocks also may underperform the market for long periods of time.
AZL DFA International Core Equity Fund | Capitalization Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Capitalization Risk – Investing in small- to mid-sized 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.
AZL DFA International Core Equity Fund | Foreign Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Foreign Securities Risk – Investing in the securities of non-U.S. issuers involves a number of risks, such as fluctuations in currency values, adverse political, social or economic developments, and differences in social and economic developments or policies.
AZL DFA International Core Equity Fund | European Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

European Investment Risk – Investments in certain countries in the European Union (the “EU”) are susceptible to high economic risks associated with high levels of debt, such as investments in sovereign debt of Greece, Italy and Spain. Efforts of the member countries to further unify their economic and monetary policies may increase the potential for the downward movement of one member country’s market to cause a similar effect on other member countries’ markets. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the EU, such as the exit of the United Kingdom (known as “Brexit”), could place its currency and banking system in jeopardy. An exit by other member countries could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect a fund’s investments.
AZL DFA International Core Equity Fund | Depositary Receipt Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Depositary Receipt Risk – Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. Investing in these instruments may expose a fund to credit risk with respect to the issuer of the depositary receipt, in addition to the risks of the underlying investment.
AZL DFA International Core Equity Fund | Currency Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Currency Risk – Investing in securities that trade in and receive revenues in foreign currencies creates risk because foreign currencies may decline relative to the U.S. dollar, resulting in a potential loss to a fund. In the case of hedging positions, the U.S. dollar may decline in value relative to the currency that has been hedged.
AZL DFA International Core Equity Fund | Derivatives Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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. Derivatives are subject to a number of other risks, such as liquidity risk, interest rate risk, market risk, credit risk, counterparty risk, and selection risk. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value may not correlate perfectly with the underlying asset, rate, or index. Using derivatives may result in losses, possibly in excess of the principal amount invested.
AZL DFA International Core Equity Fund | Futures Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Futures Risk – The value of futures contracts depend primarily upon the price of the securities, indexes, commodities, currencies or other instruments underlying them. Price movements are also influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary, and exchange control programs and policies of governments, and national and international political and economic events and policies. The cost of futures may also be related, in part, to the degree of volatility of the underlying indices, securities, currencies, or other assets. Accordingly, futures on highly volatile indices, securities, currency, or other assets may be more expensive than futures on other investments. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.
