If these sales charges (loads) were included, your costs would be higher. 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 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

In addition, falling interest rates may cause an issuer to redeem, call or refinance a security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities may be subject to greater price fluctuations than shorter maturity debt securities. Bonds and other debt securities are subject to credit risk, which is the possibility that the credit strength of an issuer will weaken and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default.</li></ul><ul><li><i> Credit risk </i> &#8211; The Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations.</li></ul><ul><li><i> Currency risk </i> &#8211; The value of the Master Fund&#8217;s shares may change as a result of changes in exchange rates reducing the value of the U.S. dollar value of the Master Fund&#8217;s foreign investments.</li></ul><ul><li><i> Emerging markets risk </i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions or from problems in security registration or settlement and custody. The Fund will also be subject to the risk of negative foreign currency rate fluctuations.</li></ul><ul><li><i> Foreign securities risk </i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investment. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i>High-yield bonds, lower-rated bond, and unrated securities </i> &#8211; High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as &#8220;junk bonds,&#8221; and are considered below &#8220;investment-grade&#8221; by national ratings agencies. Junk bonds are subject to the increased risk of an issuer&#8217;s inability to meet principal and interest payment obligations.</li></ul><ul><li><i> Interest rate risk </i> &#8211; When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equity investments, such as utilities and real estate securities, may be sensitive to interest rate changes. </li></ul><ul><li><i>Liquidity risk </i> &#8211; Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at advantageous times or prices.</li></ul><ul><li><i> Managed portfolio risk </i> &#8211; As an actively managed portfolio, the value of the Fund&#8217;s investments could decline because the financial condition of an issuer may change (due to such factors as management performance, reduced demand or overall market changes), financial markets may fluctuate or overall prices may decline, or the manager&#8217;s investment techniques could fail to achieve the Fund&#8217;s investment objective.</li></ul><ul><li><i> Market risk </i> &#8211; All forms of securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic conditions, or particular industries represented in the markets, and competitive conditions.</li></ul><ul><li><i> Non-diversification risk </i> &#8211; With a smaller number of different issuers, there is more risk than holding a larger number of issuers, since changes in the financial condition or market status of a single issuer may cause greater fluctuation of total return and share price of a non-diversified portfolio.</li></ul><ul><li><i>Thinly traded securities risk </i> &#8211; There may be little trading in the secondary market for particular bonds or other debt securities, which may make them more difficult to value or sell.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. 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 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Normally, the Master Global Small Capitalization Fund invests at least 80% of its net assets in growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, measured at the time of purchase. However, the Fund&#8217;s holdings of small capitalization stocks may fall below the 80% threshold due to subsequent market action. The Master Global Small Capitalization Fund currently defines &#8220;small market capitalization&#8221; companies to be companies with market capitalizations of $3.5 billion or less.</p><p>Under normal circumstances, the Master Global Small Capitalization Fund invests a significant portion of its assets outside the United States. The Master Global Small Capitalization Fund normally invests a portion of its assets in common stocks and other securities of companies in emerging market countries and expects to be invested in numerous countries around the world.</p><p> The Master Global Small Capitalization Fund is designed for investors seeking capital appreciation through stocks. Investors in the Master Global Capitalization Fund should have a long-term perspective and, for example, be able to tolerate potentially sharp, short-term declines in value.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

If these sales charges (loads) were included, your costs would be higher. 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 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

If these sales charges (loads) were included, your costs would be higher. 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 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

If the Fund provides this disclosure, also disclose the period for which the expense reimbursement or fee waiver arrangement is expected to continue, and briefly describe who can terminate the arrangement and under what circumstances.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table truefalseLess waiver/ reimbursement0rr_FeeWaiverOrReimbursementOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[2]1truetruetrue0.00800.0080falsefalsefalsetruefalse2truetruetrue0.00800.0080falsefalsefalsetruefalseOthernanafalsefalseLess waiver/ reimbursement7falseRowprimaryElement*10false0rr_NetExpensesOverAssetsrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalsetotallabel1truetruetrue0.01450.0145falsefalsefalsetruefalse2truetruetrue0.01200.0120falsefalsefalsetruefalseOtherrr:NonNegativePure4TypepureTotal Annual Fund Operating Expenses.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table truefalseTotal Annual Net Expenses0rr_NetExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.01450.0145falsefalsefalsetruefalse2truetruetrue0.01200.0120falsefalsefalsetruefalseOthernanafalsefalseTotal Annual Net Expenses1The fee table and the example reflect the expenses of both the Fund and the Master Fund.2JNAM has entered into a contractual agreement with the Fund under which it will waive a portion (currently 0.80%) of its advisory fee for such time as the Fund is operated as a Fund, because during that time it will not be providing the portfolio management portion of the advisory and management services.

In determining whether a country is qualified, the Master Fund will consider such factors as the country&#8217;s per capita gross domestic product; the percentage of the country&#8217;s economy that is industrialized; market capital as a percentage of gross domestic product; the overall regulatory environment; the presence of government regulation limiting or banning foreign ownership; and restrictions on repatriation of initial capital, dividends, interest and/or capital gains.</p><p>The Master Fund may invest in equlty securities of any company, regardless of where it is based, if the Fund&#8217;s investment adviser determines that a significant portion of the company&#8217;s assets or revenues (generally 20% or more) is attributable to developing countries.

Financial statements may not be accurate and may reflect differing approaches, for example, of auditing and reporting standards, foreign and other jurisdictional requlrements and affect the ability to identify appropriate investment opportunities.</li></ul><ul><li><i>Bonds risk</i> &#8211; Rising interest rates will generally cause the prices of bonds and other debt securities to fall. In addition, falling interest rates may cause an issuer to redeem, call or refinance a security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities may be subject to greater price fluctuations than shorter maturity debt securities. Bonds and other debt securities are subject to credit risk, which is the possibility that the credit strength of an issuer will weaken and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default.</li></ul><ul><li><i>Credit risk</i> &#8211; The Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations.</li></ul><ul><li><i>Currency risk</i> &#8211; The value of the Master Fund&#8217;s shares may change as a result of changes in exchange rates reducing the value of the U.S. dollar value of the Master Fund&#8217;s foreign investments.</li></ul><ul><li><i> Emerging markets risk</i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions or from problems in security registration or settlement and custody. The Fund will also be subject to the risk of negative foreign currency rate fluctuations.</li></ul><ul><li><i> Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investment. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquld markets.</li></ul><ul><li><i> Growth investing risk</i>&#8211; Growth stocks are generally priced based on future or anticipated earnings and can perform differently from the market as a whole or other types of stocks.</li></ul><ul><li><i> High yield bonds, lower-rated bonds, and unrated securities</i> &#8211; High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as &#8220;junk bonds,&#8221; and are considered below &#8220;investment-grade&#8221; by national ratings agencies. Junk bonds are subject to the increased risk of an issuer&#8217;s inability to meet principal and interest payment obligations.</li></ul><ul><li><i>Interest rate risk</i> &#8211; When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equlty investments, such as utilities and real estate securities, may be sensitive to interest rate changes.</li></ul><ul><li><i>Liquldity risk</i> &#8211; Investments in securities that are difficult to purchase or sell (illiquld or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at advantageous times or prices.</li></ul><ul><li><i>Managed portfolio risk</i> &#8211; As an actively managed portfolio, the value of the Fund&#8217;s investments could decline because the financial condition of an issuer may change (due to such factors as management performance, reduced demand or overall market changes), financial markets may fluctuate or overall prices may decline, or the manager&#8217;s investment techniques could fail to achieve the Fund&#8217;s investment objective.</li></ul><ul><li><i>Market risk</i> &#8211; All forms of securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic conditions, or particular industries represented in the markets, and competitive conditions.</li></ul><ul><li><i> Small cap investing risk</i> &#8211; Investing in smaller, newer companies generally involves greater risks than investing in larger, more established ones.</li></ul><ul><li><i>Thinly traded securities risk</i> &#8211; There may be little trading in the secondary market for particular bonds or other debt securities, which may make them more difficult to value or sell.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Present the corresponding numerical return adjacent to each bar. If the Fund's fiscal year is other than a calendar year, include the year-to-date return information as of the end of the most recent quarter in a footnote to the bar chart. Following the bar chart, disclose the Fund's highest and lowest return for a quarter during the 10 years or other period of the bar chart.

When a Multiple Class Fund offering one or more Classes offers a new Class in a prospectus that does not offer the shares of any other Class, include the bar chart with annual total returns for any other existing Class for the first year that the Class is offered. Explain in a footnote that the returns are for a Class that is not offered in the prospectus that would have substantially similar annual returns because the shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that the Classes do not have the same expenses. Include return information for the other Class reflected in the bar chart in the performance table.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph instructions -Clause 3 -Exhibit b -Subsection b falsefalseAnnual Return Caption [Text]159false0rr_BarChartTableTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2falsefalsefalse00<div> &lt;div style="display:none;"&gt;~ http://jackson.com/role/AnnualTotalReturnsBarChartJNLAmericanFundsNewWorldFund column period compact * column rr_ProspectusShareClassAxis compact * row primary compact * row dei_DocumentInformationDocumentAxis compact jnl_S000028043_Member * row dei_LegalEntityAxis&#160; compact jnl_S000028043_Member * ~&lt;/div&gt; </div>falsefalseBarChart6.jpg<div> &lt;div style="display:none;"&gt;~ http://jackson.com/role/AnnualTotalReturnsBarChartJNLAmericanFundsNewWorldFund column period compact * column rr_ProspectusShareClassAxis compact * row primary compact * row dei_DocumentInformationDocumentAxis compact jnl_S000028043_Member * row dei_LegalEntityAxis&#160; compact jnl_S000028043_Member * ~&lt;/div&gt; </div>falsehttp://jackson.com/role/AnnualTotalReturnsBarChartJNLAmericanFundsNewWorldFundfalsefalse0200506 - Schedule - Annual Total Returns (Bar Chart)truefalsefalse1falseColumnperiodPeriod*Columndei_DocumentInformationDocumentAxisAxis*ColumnunitUnit*duration2010-05-02T00:00:002011-05-01T00:00:00falsefalseJNL/American Funds New World Funddei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldijnl_S000028043Memberdei_DocumentInformationDocumentAxisexplicitMemberJNL/American Funds New World FundUSDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170falseUSDfalsefalse$1falseRowprimaryElement*4false0rr_AnnualReturn2001rrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truetruefalse-0.0399-0.0399falsefalsefalsetruefalseOtherxbrli:pureItemTypepureIf the Fund has annual returns for at least one calendar year, provide a bar chart showing the Fund's annual total returns for each of the last 10 calendar years (or for the life of the Fund if less than 10 years), but only for periods subsequent to the effective date of the Fund's registration statement.

Include return information for the other Class reflected in the bar chart in the performance table.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph instructions -Clause 1 -Exhibit a -Subsection b falsefalseAnnual Return, Column [Text]271false0rr_BarChartTableTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2falsefalsefalse00<div> &lt;div style=""display:none;""&gt;~ http://jackson.com/role/AnnualTotalReturnsBarChartJNLInstitutionalAltSixtyFiveFund column period compact * column rr_ProspectusShareClassAxis compact * row primary compact * row dei_DocumentInformationDocumentAxis compact jnl_S000025072_Member * row dei_LegalEntityAxis&#160; compact jnl_S000025072_Member * ~&lt;/div&gt; </div>falsefalseBarChart10.jpg<div> &lt;div style=""display:none;""&gt;~ http://jackson.com/role/AnnualTotalReturnsBarChartJNLInstitutionalAltSixtyFiveFund column period compact * column rr_ProspectusShareClassAxis compact * row primary compact * row dei_DocumentInformationDocumentAxis compact jnl_S000025072_Member * row dei_LegalEntityAxis&#160; compact jnl_S000025072_Member * ~&lt;/div&gt; </div>falsehttp://jackson.com/role/AnnualTotalReturnsBarChartJNLInstitutionalAltSixtyFiveFundfalsefalse0200510 - Schedule - Annual Total Returns (Bar Chart)truefalsefalse1falseColumnperiodPeriod*Columndei_DocumentInformationDocumentAxisAxis*ColumnunitUnit*duration2010-05-02T00:00:002011-05-01T00:00:00falsefalseJNL Institutional Alt 65 Funddei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldijnl_S000025072Memberdei_DocumentInformationDocumentAxisexplicitMemberJNL Institutional Alt 65 FundUSDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170falseUSDfalsefalse$1falseRowprimaryElement*4false0rr_AnnualReturn2010rrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truetruefalse0.15850.1585falsefalsefalsetruefalseOtherxbrli:pureItemTypepureIf the Fund has annual returns for at least one calendar year, provide a bar chart showing the Fund's annual total returns for each of the last 10 calendar years (or for the life of the Fund if less than 10 years), but only for periods subsequent to the effective date of the Fund's registration statement.

The value of equity securities purchased by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry. In addition, they may decline due to general market conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.</li></ul><ul><li><i>Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investment.These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i>Industry concentration risk</i> &#8211; Greater emphasis or programmed concentration on investments in a particular industry may result in significant share value fluctuatation in response to events affecting that industry.</li></ul><ul><li><i>Interest rate risk</i>&#8211; When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equity investments, such as utilities and real estate securities, may be sensitive to interest rate changes.</li></ul><ul><li><i>Liquidity risk</i> &#8211; Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at advantageous times or prices.</li></ul><ul><li><i>Market risk</i> &#8211; All forms of securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic conditions, or particular industries represented in the markets, and competitive conditions.</li></ul><ul><li><i>Mid-capitalization investing risk</i> &#8211; The prices of securities of mid-capitalization companies tend to fluctuate more widely and erratically than those of larger, more established companies.</li></ul><ul><li><i>Natural resource related securities risk</i> &#8211; Because the Fund concentrates its investments in natural resource related securities, the Fund is subject to the risks associated with natural resource investments in addition to the general risk of the stock market. This means the Fund is more vulnerable to the price movements of natural resources and factors that particularly affect the oil, gas, mining, energy, chemicals, paper, steel or agriculture sectors than a more broadly diversified fund. Because the Fund invests primarily in companies with natural resource assets, there is the risk that the Fund will perform poorly during a downturn in natural resource prices.</li></ul><ul><li><i> Non-diversification risk</i> &#8211; With a smaller number of different issuers, there is more risk than holding a larger number of issuers, since changes in the financial condition or market status of a single issuer may cause greater fluctuation total return and share price of a non-diversified portfolio.</li></ul><ul><li><i>Precious metals related securities risk</i> &#8211; Prices of precious metals and of precious metal related securities historically have been very volatile. The high volatility of precious metal prices may adversely affect the financial condition of companies involved with precious metals. The production and sale of precious metals by governments or central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals. Other factors that may affect the prices of precious metals and securities related to them include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals.</li></ul><ul><li><i>Prepayment risk</i> &#8211; During periods of falling interest rates, there is the risk that a debt security with a high stated interest rate will be prepaid before its expected maturity date and that the Fund may have to reinvest the proceeds in an investment that may have lower yields than the yield on the prepaid debt security.</li></ul><ul><li><i>Sector risk</i> &#8211; Investment of a significant portion in the securities of companies involved in the financial services sector carries greater risk of adverse developments in general economic conditions, legal, cultural or technological developments. in a sector affecting performance.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Current allocations may be different, and therefore, actual amounts for subsequent periods may be higher or lower than those shown above. 3JNAM has entered into a contractual agreement with the Fund under which it will waive a portion (0.66%) of its advisory fee for such time as the Fund is operated as a Fund, because during that time it will not be providing the portfolio management portion of the advisory and management services.

These costs, which are not reflected in annual fund operating expenses or in the expense example, affect the Fund&#8217;s and Master Fund's performance.<div style="font-face: arial" align="left"><table style="font-size:10pt" cellpadding="0" cellspacing="0" border="0" width="100%"><tr style="font-size:0pt"><td width="60%" style="border-bottom:2px solid #000000">&nbsp;</td><td width="40%" style="border-bottom:2px solid #000000">&nbsp;</td></tr><tr><td style="border-left:2px solid #000000; border-bottom:2px solid #000000; border-right:2px solid #000000"><b>Period</b></td><td style="border-bottom:2px solid #000000; border-right:2px solid #000000" align="center">&nbsp;&nbsp;<b>Master Fund</b></td></tr><tr><td style="border-left:2px solid #000000; border-bottom:2px solid #000000; border-right:2px solid #000000">1/1/2010 - 12/31/2010 </td><td style="border-bottom:2px solid #000000; border-right:2px solid #000000" align="center">29%</td></tr></table><div>&nbsp;</div><table style="font-size:10pt" cellpadding="0" cellspacing="0" border="0" width="100%"><tr style="font-size:0pt"><td width="60%" style="border-bottom:2px solid #000000">&nbsp;</td><td width="40%" style="border-bottom:2px solid #000000">&nbsp;</td></tr><tr><td style="border-left:2px solid #000000; border-bottom:2px solid #000000; border-right:2px solid #000000"><b>Period</b></td><td style="border-bottom:2px solid #000000; border-right:2px solid #000000" align="center">&nbsp;&nbsp;<b>Class A</b></td></tr><tr><td style="border-left:2px solid #000000; border-bottom:2px solid #000000; border-right:2px solid #000000">10/11/2010 - 12/31/2010 </td><td style="border-bottom:2px solid #000000; border-right:2px solid #000000" align="center">5%</td></tr></table><div>&nbsp;</div><table style="font-size:10pt" cellpadding="0" cellspacing="0" border="0" width="100%"><tr style="font-size:0pt"><td width="60%" style="border-bottom:2px solid #000000">&nbsp;</td><td width="40%" style="border-bottom:2px solid #000000">&nbsp;</td></tr><tr><td style="border-left:2px solid #000000; border-bottom:2px solid #000000; border-right:2px solid #000000"><b>Period</b></td><td style="border-bottom:2px solid #000000; border-right:2px solid #000000" align="center">&nbsp;&nbsp;<b>Class B</b></td></tr><tr><td style="border-left:2px solid #000000; border-bottom:2px solid #000000; border-right:2px solid #000000">10/11/2010 - 12/31/2010 </td><td style="border-bottom:2px solid #000000; border-right:2px solid #000000" align="center">5%</td></tr></table></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDisclose the portfolio turnover rate provided in response to Item 14(a) for the most recent fiscal year (or for such shorter period as the Fund has been in operation).

The Master Fund invests in a portfolio of equity, debt and money market securities. Generally, the Master Fund&#8217;s portfolio will invest in both equity and debt securities. Equity securities include common stock, preferred stock, securities convertible into common stock, or securities or other instruments whose price is linked to the value of common stock. The Master Fund uses derivatives as a means of managing exposure to foreign currencies and other adverse market movements, as well as to increase returns.</p><p>At any given time, however, the Master Fund may emphasize either debt securities or equity securities. In selecting equity investments, the Master Fund mainly seeks securities that Fund management believes are undervalued. The Master Fund may buy debt securities with varying maturities. The Master Fund may invest up to 35% of its total assets in high yield or junk bonds. Junk bonds are fixed-income securities rated below investment-grade by independent rating agencies or are bonds that are unrated but that Master Fund management believes are of comparable quality. The Master Fund may invest in corporate loans.</p><p>When choosing investments, Master Fund management considers various factors, including opportunities for equity or debt investments to increase in value, expected dividends and interest rates. The Master Fund generally seeks diversification across markets, industries and issuers as one of its strategies to reduce volatility. The Master Fund may invest in the securities of companies of any market capitalization. The Master Fund may also invest in Real Estate Investment Trusts ("REITs"). Market capitalization is the number of shares of a company&#8217;s stock, multiplied by the price per share of that stock. Market capitalization is a measure of a company&#8217;s size.</p><p>Generally, the Master Fund will invest primarily in the securities of corporate and governmental issuers located anywhere in the world. The Master Fund may emphasize foreign securities when Master Fund management expects these investments to outperform U.S. securities. When choosing investment markets, Master Fund management considers various factors, including economic and political conditions, potential for economic growth and possible changes in currency exchange rates. In addition to investing in foreign securities, the Master Fund actively manages its exposure to foreign currencies through the use of forward currency contracts and other currency derivatives. From time to time, the Master Fund may own foreign cash equivalents or foreign bank deposits as part of the Master Fund&#8217;s investment strategy. The Master Fund will also invest in non-U.S. currencies, however, the Master Fund may underweight or overweight a currency (relative to the Reference Benchmark) based on the Master Fund management team&#8217;s outlook. The Master Fund may also invest in non-convertible debt securities. Non-convertible debt securities will generally be longer-term securities with the potential for capital appreciation through changes in interest rates, exchange rates or the general perception of the creditworthiness of issuers in certain countries. The Master Fund may also invest in non-convertible debt securities to generate income.</p><p>The Master Fund&#8217;s composite Reference Benchmark has at all times since the Master Fund&#8217;s formation included a 40% weighting in non-U.S. securities. The Reference Benchmark is an unmanaged weighted index comprised as follows: 36% of the Standard &#038; Poor&#8217;s (&#8220;S&#038;P&#8221;) 500 Index; 24% FTSE World Index (Ex-U.S.) Equities; 24% BofA Merrill Lynch Treasury Index GA05; and 16% Citigroup Non-US Dollar World Government Bond Index. Throughout its history, the Master Fund has maintained a weighting in non-U.S. securities, often exceeding the 40% Reference Benchmark weighting and rarely falling below this allocation. Under normal circumstances, the Master Fund anticipates it will continue to allocate a substantial amount (approximately 40% or more &#8212; unless market conditions are not deemed favorable by Master Fund Management, in which case the Master Fund would invest at least 30%) &#8212; of its total assets in securities (i) of foreign government issuers; (ii) of issuers organized or located outside the U.S.; (iii) of issuers which primarily trade in a market located outside the U.S.; or (iv) of issuers doing a substantial amount of business outside the U.S., which the Master Fund considers to be companies that derive at least 50% of their revenue or profits from business outside the U.S. or have at least 50% of their sales or assets outside the U.S. The Master Fund will allocate its assets among various regions and countries, including the United States (but in no less than three different countries). For temporary defensive purposes the Master Fund may deviate very substantially from the allocation described above.</p><p>The Master Fund may seek to provide exposure to the investment returns of real assets that trade in the commodity markets through investment in commodity-linked derivative instruments and investment vehicles that exclusively invest in precious metals such as exchange traded funds, which are designed to provide this exposure without direct investment in physical commodities or commodities futures contracts. The Master Fund may also gain exposure to commodity markets by investing up to 25% of its total assets in BlackRock Cayman Global Allocation Portfolio I, Ltd. (the &#8220;Subsidiary&#8221;), a wholly owned subsidiary of the Master Fund formed in the Cayman Islands, which invests primarily in commodity-related instruments. The Subsidiary (unlike the Master Fund) may invest without limitation in commodity-related instruments. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Master Fund.</p><p>Total investment return is the combination of capital appreciation and investment income.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

As with any mutual fund, the value of the Feeder Fund&#8217;s shares will change, and you could lose money by investing in the Fund.</p><p>These risks relate primarily to the Master Fund.</p><ul><li><i>Call risk</i> &#8211; Call risk is the risk that, during a period of falling interest rates, the issuer may redeem a security by repaying it early, which may reduce the Fund&#8217;s income if the proceeds are reinvested at lower interest rates.</li></ul><ul><li><i>Commodity risk</i> &#8211; Commodities investments and/or commodity-linked derivative instruments, especially if leveraged, may entail greater volatility from a variety of causes than traditional securities.</li></ul><ul><li><i>Credit risk</i> &#8211; The Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations.</li></ul><ul><li><i>Derivatives risk</i> &#8211; Investing in derivative instruments, such as, swaps, options, futures contracts, forward currency contracts, indexed securities and asset-backed securities, to be announced (TBAs) securities, interest rate swaps, credit default swaps, and certain exchange traded funds, involves risks, including liquidity, interest rate, market, counterparty, credit and management risks, mispricing or improper valuation. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market.</li></ul><ul><li><i> Emerging markets risk</i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions or from problems in security registration or settlement and custody. The Fund will also be subject to the risk of negative foreign currency rate fluctuations.</li></ul><ul><li><i>Equity securities risk</i> &#8211; Common and preferred stocks represent equity ownership in a company. Stock markets are volatile. The price of equity securities will fluctuate and can decline and reduce the value of a portfolio investing inequities. The value of equity securities purchased by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry. In addition, they may decline due to general market conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.</li></ul><ul><li><i> Extension risk</i> &#8211; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall. Rising interest rates tend to extend the duration of securities, making them more sensitive to changes in interest rates. The value of longer-term securities generally changes more in response to changes in interest rates than shorter-term securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.</li></ul><ul><li><i>Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i> Interest rate risk</i> &#8211; When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equity investments, such as utilities and real estate securities, may be sensitive to interest rate changes.</li></ul><ul><li><i>High yield bonds, lower-rated bonds, and unrated securities</i> &#8211; High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as &#8220;junk bonds,&#8221; and are considered below &#8220;investment-grade&#8221; by national ratings agencies. Junk bonds are subject to the increased risk of an issuer&#8217;s inability to meet principal and interest payment obligations.</li></ul><ul><li><i>Loans risk</i> &#8211; Bank loans, corporate loans, loan participations and assignments involve credit risk, interest rate risk, liquidity risk, and the general risks of being a lender.</li></ul><ul><li><i> Market risk</i> &#8211; All forms of securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic conditions, or particular industries represented in the markets, and competitive conditions.</li></ul><ul><li><i> Mid-capitalization investing risk </i>&#8211; The prices of securities of mid-capitalization companies tend to fluctuate more widely and erratically than those of larger, more established companies.</li></ul><ul><li><i> Non-diversification risk</i> &#8211; With a smaller number of different issuers, there is more risk than holding a larger number of issuers, since changes in the financial condition or market status of a single issuer may cause greater fluctuation total return and share price of a non-diversified portfolio.</li></ul><ul><li><i> Real estate investment risk</i> &#8211; An investment in the Fund may be closely linked to the performance of the real estate markets and share prices may rise and fall more than the value of shares of a fund invested in a broader range of companies.</li></ul><ul><li><i> Small cap investing risk</i> &#8211; Investing in smaller, newer companies generally involves greater risks than investing in larger, more established ones.</li></ul><ul><li><i>Subsidiary risk</i> &#8211; By investing in the Subsidiary, the Master Fund is indirectly exposed to the risks associated with the Subsidiary&#8217;s investments. The commodity-related instruments held by the Subsidiary are generally similar to those that are permitted to be held by the Master Fund and are subject to the same risks that apply to similar investments if held directly by the Master Fund (see &#8220;Commodity Risk&#8221; above). There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (&#8220;1940 Act&#8221;), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. However, the Master Fund wholly owns and controls the Subsidiary, and the Master Fund and the Subsidiary are both managed by BlackRock, making it unlikely that the Subsidiary will take action contrary to the interests of the Master Fund and its shareholders. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Master Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information (&#8220;SAI&#8221;) and could adversely affect the Master Fund.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market. </li></ul><ul><li><i>Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investment. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i>Interest rate risk</i> &#8211; When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equity investments, such as utilities and real estate securities, may be sensitive to interest rate changes.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market. </li></ul><ul><li><i> Emerging markets risk</i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries.

The Fund will also be subject to the risk of negative foreign currency rate fluctuations. </li></ul><ul><li><i> Foreign securities risk </i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investment.

These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market.</li></ul><ul><li><i>Equity-linked notes risk &#8211;</i> Investments in ELNs often have risks similar to their underlying securities, which could include management risk, market risk and, as applicable, foreign securities and currency risks. In addition, since ELNs are in note form, ELNs are also subject to certain debt securities risks, such as interest rate and credit risk. Should the prices of the underlying securities move in an unexpected manner, the Fund may not achieve the anticipated benefits of an investment in an ELN, and may realize losses, which could be significant and could include the Fund&#8217;s entire principal investment. An investment in an ELN is also subject to counterparty risk, which is the risk that the issuer of the ELN will default or become bankrupt and the Fund will have difficulty being repaid, or fail to be repaid, the principal amount of, or income from, its investment. Investments in ELNs are also subject to liquidity risk, which may make ELNs difficult to sell and value. In addition, ELNs may exhibit price behavior that does not correlate with the underlying securities or a fixed-income investment.</li></ul><ul><li><i>Foreign securities risk &#8211;</i> Investments in foreign securities involve risks not typically associated with U.S. investment. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i>High-yield bonds, lower-rated bonds, and unrated securities &#8211;</i> High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as "junk bonds," and are considered below "investment-grade" by national ratings agencies. Junk bonds are subject to the increased risk of an issuer&#8217;s inability to meet principal and interest payment obligations.</li></ul><ul><li><i>Interest rate risk &#8211;</i> When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equity investments, such as utilities and real estate securities, may be sensitive to interest rate changes.</li></ul><ul><li><i>Investment value style risk &#8211;</i> Value stocks may not increase in price if other investors fail to recognize a company&#8217;s value or the factors that are expected to increase the price of a security do not occur. In the past, over the long-term, the growth and value stock categories have had similar returns; however, each category sometimes outperforms the other for longer periods of time.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Include return information for the other Class reflected in the bar chart in the performance table.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph instructions -Clause 1 -Exhibit a -Subsection b falsefalseAnnual Return, Column [Text]578false0rr_BarChartTableTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<div> &lt;div&gt; &amp;lt;div style="display:none;"&amp;gt;~ http://jackson.com/role/AnnualTotalReturnsBarChartJNLFranklinTempletonInternationalSmallCapGrowthFund column rr_ProspectusShareClassAxis compact jnl_C000068007Member ~&amp;lt;/div&amp;gt; &lt;/div&gt; </div>falsefalseBarChart29.jpg<div> &lt;div&gt; &amp;lt;div style="display:none;"&amp;gt;~ http://jackson.com/role/AnnualTotalReturnsBarChartJNLFranklinTempletonInternationalSmallCapGrowthFund column rr_ProspectusShareClassAxis compact jnl_C000068007Member ~&amp;lt;/div&amp;gt; &lt;/div&gt; </div>falsehttp://jackson.com/role/AnnualTotalReturnsBarChartJNLFranklinTempletonInternationalSmallCapGrowthFundfalsefalse0200521 - Schedule - Annual Total Returns (Bar Chart)truefalsefalse1falseColumnperiodPeriod*Columnrr_ProspectusShareClassAxisAxisjnl_C000068007MemberColumndei_DocumentInformationDocumentAxisAxis*ColumnunitUnit*duration2010-05-02T00:00:002011-05-01T00:00:00falsefalseJNL/Franklin Templeton International Small Cap Growth Fund-Class Brr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldijnl_C000068007Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseJNL/Franklin Templeton International Small Cap Growth Funddei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldijnl_S000019479Memberdei_DocumentInformationDocumentAxisexplicitMemberJNL/Franklin Templeton International Small Cap Growth Fund-Class BJNL/Franklin Templeton International Small Cap Growth FundUSDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170falseUSDfalsefalse$1falseRowprimaryElement*4false0rr_AnnualReturn2008rrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truetruefalse-0.5400-0.5400falsefalsefalsetruefalse2truetruefalse-0.5384-0.5384falsefalsefalsetruefalseOtherxbrli:pureItemTypepureIf the Fund has annual returns for at least one calendar year, provide a bar chart showing the Fund's annual total returns for each of the last 10 calendar years (or for the life of the Fund if less than 10 years), but only for periods subsequent to the effective date of the Fund's registration statement.

Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market.</li></ul><ul><li><i>Emerging markets risk</i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions or from problems in security registration or settlement and custody. The Fund will also be subject to the risk of negative foreign currency rate fluctuations.</li></ul><ul><li><i> Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investment. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i> Investment value style risk</i> &#8211; Value stocks may not increase in price if other investors fail to recognize a company&#8217;s value or the factors that are expected to increase the price of a security do not occur. In the past, over the long-term, the growth and value stock categories have had similar returns; however, each category sometimes outperforms the other for longer periods of time.</li></ul><ul><li><i>Risk arbitrage securities and distressed companies risk</i> &#8211; Companies involved in restructurings such as mergers, acquisitions, consolidations, liquidations, spin-offs, or tender or exchange offers and distressed companies present significant risks that any restructuring may not be successful and become reduced in value or worthless.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

As with any mutual fund, the value of the Fund&#8217;s shares will change, and you could lose money by investing in the Fund.</p><ul><li><i>Derivatives risk</i> &#8211; Investing in derivative instruments, such as, swaps, options, futures contracts, forward currency contracts, indexed securities and asset-backed securities, to be announced (TBAs) securities, interest rate swaps, credit default swaps, and certain exchange traded funds, involves risks, including liquidity, interest rate, market, counterparty, credit and management risks, mispricing or improper valuation. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market.</li></ul><ul><li><i>Emerging markets risk</i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions or from problems in security registration or settlement and custody. The Fund will also be subject to the risk of negative foreign currency rate fluctuations.</li></ul><ul><li><i>Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investment. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i>High-yield bonds, lower-rated bonds, and unrated securities</i> &#8211; High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as &#8220;junk bonds,&#8221; and are considered below &#8220;investment-grade&#8221; by national ratings agencies. Junk bonds are subject to the increased risk of an issuer&#8217;s inability to meet principal and interest payment obligations.</li></ul><ul><li><i>Interest rate risk</i> &#8211; When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equity investments, such as utilities and real estate securities, may be sensitive to interest rate changes.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

As with any mutual fund, the value of the Fund&#8217;s shares will change, and you could lose money by investing in the Fund.</p><ul><li><i>Derivatives risk</i> &#8211; Investing in derivative instruments, such as, swaps, options, futures contracts, forward currency contracts, indexed securities and asset-backed securities, to be announced (TBAs) securities, interest rate swaps, credit default swaps, and certain exchange traded funds, involves risks, including liquidity, interest rate, market, counterparty, credit and management risks, mispricing or improper valuation. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market.</li></ul><ul><li><i>Emerging market risk</i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions or from problems in security registration or settlement and custody. The Fund will also be subject to the risk of negative foreign currency rate fluctuations.</li></ul><ul><li><i>High-yield bonds, lower-rated bonds, and unrated securities</i> &#8211; High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as &#8220;junk bonds,&#8221; and are considered below &#8220;investment-grade&#8221; by national ratings agencies. Junk bonds are subject to the increased risk of an issuer&#8217;s inability to meet principal and interest payment obligations.</li></ul><ul><li><i>Non-diversification risk</i> &#8211; With a smaller number of different issuers, there is more risk than holding a larger number of issuers, since changes in the financial condition or market status of a single issuer may cause greater fluctuation of total return and share price of a non-diversified portfolio.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market. </li></ul><ul><li><i>Emerging markets risk</i> &#8211; Investments in emerging markets involve greater risk resulting from economic and political systems that typically are less developed, and likely to be less stable, than those of more advanced countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions or from problems in security registration or settlement and custody. The Fund will also be subject to the risk of negative foreign currency rate fluctuations.</li></ul><ul><li><i>Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i>Investments in initial public offerings of securities (&#8220;IPO&#8221;s)</i> &#8211; IPOs issued by unseasoned companies with little or no operating history are risky and highly volatile.</li></ul><ul><li><i>Investment value style risk</i> &#8211; Value stocks may not increase in price if other investors fail to recognize a company&#8217;s value or the factors that are expected to increase the price of a security do not occur. In the past, over the long-term, the growth and value stock categories have had similar returns; however, each category sometimes outperforms the other for longer periods of time.</li></ul><ul><li><i>Market risk</i> &#8211; All forms of securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic conditions, or particular industries represented in the markets, and competitive conditions.</li></ul><ul><li><i>Mid-capitalization investing risk</i> &#8211; The prices of securities of mid-capitalization companies tend to fluctuate more widely and erratically than those of larger, more established companies.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from 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 you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. 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 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The amount includes the costs associated with the Fund's short sales on equity securities. When a cash dividend is declared on a security for which the Fund holds a short position, the Fund incurs the obligation to pay an amount equal to that dividend to the lender of the shorted security. In addition, the Fund incurs borrowing fees related to short sale transactions. The annualized amounts of dividend expense on short sales and borrowing fees related to short sales for the period were 0.72%. The Fund's actual dividend expense and borrowing fees on securities sold short in future periods may be significantly higher or lower than the amounts above due to, among other factors, the extent of the Fund's short positions, the actual dividends paid with respect to the securities the Fund sells short, and the actual timing of the Fund's short sale transactions, each of which is expected to vary over time. 26Annual Fund Operating Expenses JNL/Goldman Sachs U.S. Equity Flex FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnperiodPeriod*Columndei_DocumentInformationDocumentAxisAxis*Columnrr_ProspectusShareClassAxisAxis*ColumnunitUnit*RowprimaryElement*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to OperatingExpensesData.No authoritative reference available.falsefalseAnnual Fund Operating Expenses [Table]735false0rr_ExpenseExampleHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2falsefalsefalse00Expense Example.falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringHeading for Expense Example.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 4 -Subsection instructions falsefalseExpense Example [Heading]736false0rr_ExpenseExampleNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2falsefalsefalse00This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

In seeking to outperform its benchmark index, the S&#038;P 500 Index, the Fund will hold long securities that the Sub-Adviser believes are more likely to outperform the index, and will take short positions in securities the Sub-Adviser believes will underperform the index. This strategy offers the portfolio management team increased flexibility in expressing their views, whether positive or negative, on certain issuers. The Sub-Adviser intends to maintain a net long exposure (the market value of long positions minus the market value of short positions divided by the total market value of the portfolio) of approximately 100% and a beta of 1. The Sub-Adviser will normally target long positions of 130% of the Fund&#8217;s net assets, and short positions of 30% of the Fund&#8217;s net assets, but may vary from these targets.</p><p>Beta is a measure of a stock&#8217;s volatility relative to the volatility of the market. A fund that has the same volatility as that of the market has a beta of 1. If a fund has a beta less than 1, a fund is less volatile than the market. On the other hand, a fund that has a beta greater than 1 is more volatile than the market. For this Fund, the market is considered to be all of the stocks included in the S&#038;P 500 Index.</p><p>When the Fund sells a security short, it borrows the security from a lender and then sells it to a third party. To complete or close the short transaction, the Fund must acquire the same security in the market and return it to the lender. If the Fund can close the transaction by buying the security at a price lower than the price paid by the third party, a profit results; however, if the price rises, a loss occurs. When the Fund makes a short sale, the Fund may use all or a portion of the cash proceeds of the short sale to purchase additional securities or for any other Fund purpose. This is a form of leverage, and when the Fund does this, it is required to pledge replacement collateral as security to the broker, and may use securities it owns to meet any such collateral obligations.</p><p>The Sub-Adviser&#8217;s investment philosophy is based on the belief that investing should thoughtfully weigh two important attributes of a stock: price and prospects. The Sub-Adviser believes a company&#8217;s prospective ability to generate high cash flow returns on capital will strongly influence investment success. The Fund will favor investments in equities that the Sub-Adviser believes are well-positioned, cash-generating businesses run by shareholder-oriented management teams. Conversely, the Fund will short equities where the Sub-Adviser believes the businesses have limited prospects, such as those facing deteriorating fundamentals and severe headwinds, with limited or no competitive advantage.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

When a Multiple Class Fund offering one or more Classes offers a new Class in a prospectus that does not offer the shares of any other Class, include the bar chart with annual total returns for any other existing Class for the first year that the Class is offered. Explain in a footnote that the returns are for a Class that is not offered in the prospectus that would have substantially similar annual returns because the shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that the Classes do not have the same expenses. Include return information for the other Class reflected in the bar chart in the performance table.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph instructions -Clause 3 -Exhibit b -Subsection b falsefalseAnnual Return Caption [Text]803false0rr_AnnualReturnColumnNamerrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsetruefalse00Class Bfalsefalsefalsefalsefalse2falsetruefalse00Class AfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a bar chart showing the Fund's annual total returns for each of the last 10 calendar years (or for the life of the Fund if less than 10 years), but only for periods subsequent to the effective date of the Fund's registration statement.

In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i> Interest rate risk</i> &#8211; When interest rates increase, fixed income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of equity investments, such as utilities and real estate securities, may be sensitive to interest rate changes.</li></ul><ul><li><i> Investment growth style risk</i> &#8211; Growth stock prices frequently reflect projections of future earnings or revenues, and if earnings growth expectations aren&#8217;t met their valuations may return to more typical norms, causing their stock prices to fall.</li></ul><ul><li><i> Liquidity risk</i> &#8211; Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at advantageous times or prices.</li></ul><ul><li><i> Small cap investing risk</i> &#8211; Investing in smaller, newer companies generally involves greater risks than investing in larger, more established ones.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market.</li></ul><ul><li><i>Foreign securities risk</i> &#8211; Investments in foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values as well as adverse political, social and economic developments. In addition, there may be less publicly available information and more volatile or less liquid markets.</li></ul><ul><li><i>Investment style growth risk</i> &#8211; Growth stock prices frequently already reflect projections of future earnings or revenues, and if earnings growth expectations aren&#8217;t met their valuations may return to more typical norms, causing their stock prices to fall.</li></ul><ul><li><i>Mid-capitalization investing risk</i> &#8211; The prices of securities of mid-capitalization companies tend to fluctuate more widely and erratically than those of larger, more established companies.</li></ul>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
