Performance Narrative [Text Block]

Prior to April 24, 2017, the Fund was managed by JNAM and implemented its investment strategy directly through a sub-adviser. Effective April 24, 2017, the Fund operates as a “feeder fund” of the Master Fund. Performance prior to April 24, 2017 reflects the Fund’s results when its investment strategy was implemented by a sub-adviser rather than via investment in the Master Fund. For the period from April 24, 2017 through December 31, 2017, the Fund’s performance information set forth below is the performance of the Master Fund (adjusted to reflect the fees of the Class A and Class I shares of the Fund, as applicable). For periods following January 1, 2018, the Fund’s performance information set forth below is the performance of the Feeder Fund.

 

The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compared with those of a broad-based securities market index and an additional index that the Adviser believes more closely reflects the market segments in which the Fund invests. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown. If such arrangements had not been in place, performance for those periods would have been lower. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.

 

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

 

Consistent with the Fund’s principal investment strategies, the Fund uses the 60% S&P 500 Index/40% Bloomberg U.S. Aggregate Index as the Fund’s secondary benchmark.

 

Consistent with the Fund’s principal investment strategies, the Fund uses the Bloomberg U.S. Aggregate Index as the Fund’s tertiary benchmark.

The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compared with those of a broad-based securities market index and additional indices that the Adviser believes more closely reflects the market segments in which the Fund invests. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown. If such arrangements had not been in place, performance for those periods would have been lower. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.

 

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

 

The performance data includes the performance of the JNL iShares Tactical Growth Fund, then a series of the Jackson Variable Series Trust, for periods before the Fund’s registration statement became effective.

 

Consistent with the Fund’s principal investment strategies, the Fund uses the 80% Morningstar Global Target Market Exposure Index (Net), 20% Bloomberg U.S. Aggregate Index as the Fund’s tertiary benchmark.

Prior to April 26, 2021, the Fund was managed by JNAM and implemented its investment strategy directly through a sub-adviser. Effective April 26, 2021, the Fund operates as a “feeder fund” of the Master Fund. Performance prior to April 26, 2021 reflects the Fund’s results when its investment strategy was implemented by a sub-adviser rather than via investment in the Master Fund. The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compared with those of a broad-based securities market index. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown. If such arrangements had not been in place, performance for those periods would have been lower. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.

 

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

Performance Narrative [Text Block]

Prior to April 26, 2021, the Fund was managed by JNAM and implemented its investment strategy directly through a sub-adviser. Effective April 26, 2021, the Fund operates as a “feeder fund” of the Master Fund. Performance prior to April 26, 2021 reflects the Fund’s results when its investment strategy was implemented by a sub-adviser rather than via investment in the Master Fund. The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compared with those of a broad-based securities market index. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown. If such arrangements had not been in place, performance for those periods would have been lower. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.

 

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

 

Effective April 26, 2021, the Fund was combined with JNL/Vanguard Global Bond Market Index Fund (“Acquired Fund”), with the Fund as the surviving Fund. The performance shown is the Fund’s historic performance and does not reflect the performance of the Acquired Fund.

The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compared with those of a broad-based securities market index and an additional index that the Adviser believes more closely reflects the market segments in which the Fund invests. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown, and if such arrangements had not been in place, performance for those periods would have been lower. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.

 

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compared with those of a broad-based securities market index and an additional index that the Adviser believes more closely reflects the market segments in which the Fund invests. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.

 

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

 

Effective April 27, 2020, the Fund was combined with the JNL/The London Company Focused U.S. Equity Fund (the "Acquired Fund"), a series of Jackson Variable Series Trust, with the Fund as the surviving Fund.

Performance Narrative [Text Block]

The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compared with those of a broad-based securities market index and additional indices that the Adviser believes more closely reflects the market segments in which the Fund invests. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown. If such arrangements had not been in place, performance for those periods would have been lower. Performance prior to on or about July 1, 2019 reflects the Fund's results when managed by the former sub-adviser, Standard & Poor's Investment Advisory Services LLC. Performance prior to October 21, 2024 reflects the Fund's results when managed by the former sub-adviser, Goldman Sachs Asset Management, L.P. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.

 

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

 

 

Consistent with the Fund’s principal investment strategies, the Fund uses the 42% S&P 500 Index, 40% Bloomberg U.S. Aggregate Index, 18% Morningstar Developed Markets ex-North America Target Market Exposure Index (Net) as the Fund’s tertiary benchmark.
