| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the Morningstar LSTA US Leveraged Loan Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Overall security selection contributed positively to relative performance during the period, driven primarily by selection within the Financial Institutions and Retailers sectors. Sector allocation decisions contributed positively to relative performance in the aggregate, primarily driven by the Fund’s overweight allocation to the Wirelines sector and underweight to the Transportation sector. The Fund held a position in total return swaps (Markit Iboxx USD Liquid High Yield Index). The Fund’s position was used for liquidity purposes and for tactically adjusting the risk posture of the Fund, and it contributed positively to relative performance during the period. The Fund also used interest rate futures to reduce the duration of high-yield bond holdings during the period which contributed to relative returns. Top Detractors to Performance Security selection in the Consumer Cyclical Services and Leisure sectors detracted from relative performance during the period. An underweight to the Health Care sector and an overweight to the Cable and Satellite sector detracted from relative returns during the period. The Fund employed currency forwards to seek to minimize active currency risk from investments in non-dollar denominated securities. The investment team typically views currency forwards in conjunction with the securities intended to be hedged, and on a standalone basis the currency forwards detracted from relative performance over the period. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the Morningstar LSTA US Leveraged Loan Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Overall security selection contributed positively to relative performance during the period, driven primarily by selection within the Financial Institutions and Retailers sectors. Sector allocation decisions contributed positively to relative performance in the aggregate, primarily driven by the Fund’s overweight allocation to the Wirelines sector and underweight to the Transportation sector. The Fund held a position in total return swaps (Markit Iboxx USD Liquid High Yield Index). The Fund’s position was used for liquidity purposes and for tactically adjusting the risk posture of the Fund, and it contributed positively to relative performance during the period. The Fund also used interest rate futures to reduce the duration of high-yield bond holdings during the period which contributed to relative returns. Top Detractors to Performance Security selection in the Consumer Cyclical Services and Leisure sectors detracted from relative performance during the period. An underweight to the Health Care sector and an overweight to the Cable and Satellite sector detracted from relative returns during the period. The Fund employed currency forwards to seek to minimize active currency risk from investments in non-dollar denominated securities. The investment team typically views currency forwards in conjunction with the securities intended to be hedged, and on a standalone basis the currency forwards detracted from relative performance over the period. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024, as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the Bloomberg US TIPS 1-10 Year Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation to developed non-USD sovereign debt was the largest contributor to relative performance. The Fund’s allocation to Structured Finance sectors had a positive impact on relative performance. The Fund’s allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) benefited performance, supported by structural supply shortages although the pace of home prices appreciation continued to moderate as of the end of the period. Exposure to other securitized sectors including Commercial Mortgage-Backed Securities (CMBS), Collateralized Loan Obligations (CLOs), and Asset-Backed Securities (ABS) contributed positively to relative performance. An allocation to agency mortgage backed securities pass-throughs also had a positive impact. Top Detractors to Performance The Fund’s underweight to U.S. Treasury Inflation-Protected Securities (TIPS) detracted from performance. The Fund’s tactical duration positions had a negative impact on performance during the period. Over the period, the Fund made use of derivatives in pursuit of both risk management and total returns. Derivatives usage included U.S. Treasury and non-U.S. futures to manage duration, credit default swaps and total return swaps to manage sector exposure, currency forwards both to hedge emerging markets currency risk and as part of the developed currency strategy, and CPI swaps and bond forwards to manage inflation sensitivity. Over the period, the impact of derivatives on relative performance was positive overall. The Fund’s exposure to currency forwards benefited performance while currency options was neutral. The use of bond futures to manage duration aided results and credit derivatives (e.g., credit default swap index (CDX)) exposure detracted modestly. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024, as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the Bloomberg US TIPS 1-10 Year Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation to developed non-USD sovereign debt was the largest contributor to relative performance. The Fund’s allocation to Structured Finance sectors had a positive impact on relative performance. The Fund’s allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) benefited performance, supported by structural supply shortages although the pace of home prices appreciation continued to moderate as of the end of the period. Exposure to other securitized sectors including Commercial Mortgage-Backed Securities (CMBS), Collateralized Loan Obligations (CLOs), and Asset-Backed Securities (ABS) contributed positively to relative performance. An allocation to agency mortgage backed securities pass-throughs also had a positive impact. Top Detractors to Performance The Fund’s underweight to U.S. Treasury Inflation-Protected Securities (TIPS) detracted from performance. The Fund’s tactical duration positions had a negative impact on performance during the period. Over the period, the Fund made use of derivatives in pursuit of both risk management and total returns. Derivatives usage included U.S. Treasury and non-U.S. futures to manage duration, credit default swaps and total return swaps to manage sector exposure, currency forwards both to hedge emerging markets currency risk and as part of the developed currency strategy, and CPI swaps and bond forwards to manage inflation sensitivity. Over the period, the impact of derivatives on relative performance was positive overall. The Fund’s exposure to currency forwards benefited performance while currency options was neutral. The use of bond futures to manage duration aided results and credit derivatives (e.g., credit default swap index (CDX)) exposure detracted modestly. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024, as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the Bloomberg US TIPS 1-10 Year Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation to developed non-USD sovereign debt was the largest contributor to relative performance. The Fund’s allocation to Structured Finance sectors had a positive impact on relative performance. The Fund’s allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) benefited performance, supported by structural supply shortages although the pace of home prices appreciation continued to moderate as of the end of the period. Exposure to other securitized sectors including Commercial Mortgage-Backed Securities (CMBS), Collateralized Loan Obligations (CLOs), and Asset-Backed Securities (ABS) contributed positively to relative performance. An allocation to agency mortgage backed securities pass-throughs also had a positive impact. Top Detractors to Performance The Fund’s underweight to U.S. Treasury Inflation-Protected Securities (TIPS) detracted from performance. The Fund’s tactical duration positions had a negative impact on performance during the period. Over the period, the Fund made use of derivatives in pursuit of both risk management and total returns. Derivatives usage included U.S. Treasury and non-U.S. futures to manage duration, credit default swaps and total return swaps to manage sector exposure, currency forwards both to hedge emerging markets currency risk and as part of the developed currency strategy, and CPI swaps and bond forwards to manage inflation sensitivity. Over the period, the impact of derivatives on relative performance was positive overall. The Fund’s exposure to currency forwards benefited performance while currency options was neutral. The use of bond futures to manage duration aided results and credit derivatives (e.g., credit default swap index (CDX)) exposure detracted modestly.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance International equities rose over the trailing twelve-month period ending October 31, 2024, as measured by the MSCI ACWI ex USA Index (Net). In the period, heightened market volatility coincided with notable central bank policy decisions, major political developments, and an escalating conflict in the Middle East. Lower energy prices helped to ease inflationary pressures, and resilient labor markets in the U.S., Europe, and Japan reinforced the view that the global economy could achieve a soft landing. Fund performance described below is relative to the Fund’s performance index, the MSCI ACWI ex USA Growth Index (Net), for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection contributed to relative performance during the period, driven by selection within the Communication Services, Information Technology, and Healthcare sectors. Sector allocation, a result of our bottom-up stock selection process, contributed to relative returns during the period. An underweight allocation to the Consumer Staples sector and an overweight to the Information Technology sector aided relative returns the most. Top individual contributors over the period were out-of-benchmark positions in Spotify (Communication Services) and ARM Holdings (Information Technology), as well as an overweight position in Schneider Electric (Industrials). Top Detractors to Performance Weak security selection within the Consumer Discretionary, Consumer Staples, and Financials sectors detracted from relative performance during the period. Overweight allocations to the Consumer Discretionary and Energy sectors detracted from relative returns. The largest individual detractors over the period were out-of-benchmark positions in Lululemon Athletica (Consumer Discretionary) and Schlumberger (Energy), as well as an overweight position in Davide Campari-Milano (Consumer Staples).

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance International equities rose over the trailing twelve-month period ending October 31, 2024, as measured by the MSCI ACWI ex USA Index (Net). In the period, heightened market volatility coincided with notable central bank policy decisions, major political developments, and an escalating conflict in the Middle East. Lower energy prices helped to ease inflationary pressures, and resilient labor markets in the U.S., Europe, and Japan reinforced the view that the global economy could achieve a soft landing. Fund performance described below is relative to the Fund’s performance index, the MSCI ACWI ex USA Growth Index (Net), for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection contributed to relative performance during the period, driven by selection within the Communication Services, Information Technology, and Healthcare sectors. Sector allocation, a result of our bottom-up stock selection process, contributed to relative returns during the period. An underweight allocation to the Consumer Staples sector and an overweight to the Information Technology sector aided relative returns the most. Top individual contributors over the period were out-of-benchmark positions in Spotify (Communication Services) and ARM Holdings (Information Technology), as well as an overweight position in Schneider Electric (Industrials). Top Detractors to Performance Weak security selection within the Consumer Discretionary, Consumer Staples, and Financials sectors detracted from relative performance during the period. Overweight allocations to the Consumer Discretionary and Energy sectors detracted from relative returns. The largest individual detractors over the period were out-of-benchmark positions in Lululemon Athletica (Consumer Discretionary) and Schlumberger (Energy), as well as an overweight position in Davide Campari-Milano (Consumer Staples).

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance International equities rose over the trailing twelve-month period ending October 31, 2024, as measured by the MSCI ACWI ex USA Index (Net). In the period, heightened market volatility coincided with notable central bank policy decisions, major political developments, and an escalating conflict in the Middle East. Lower energy prices helped to ease inflationary pressures, and resilient labor markets in the United States, Europe, and Japan reinforced the view that the global economy could achieve a soft landing. Fund performance described below is relative to the Top Contributors to Performance Sector allocation, a result of the investment team’s bottom-up stock selection process, contributed to relative performance mainly driven by the Fund’s overweight to the Information Technology sector and underweight allocations to the Consumer Staples and Materials sectors. Security selection within the Communication Services, Consumer Discretionary, and Real Estate sectors contributed positively to relative performance. Top individual contributors over the period were overweight positions in Taiwan Semiconductor (Information Technology) and UniCredit S.p.A. (Financials), along with an out-of-benchmark position in Spotify Technology (Communication Services). Top Detractors to Performance An overweight allocation to the Energy sector and an underweight to the Financials sector detracted from relative performance. Security selection within the Financials, Information Technology, and Utilities sectors detracted from relative results during the period. The largest individual detractors over the period were overweight positions in Reckitt Benckiser (Consumer Staples), RWE (Utilities), and Cenovus Energy (Energy).

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024, as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the Bloomberg 1-3 Year US Government/Credit Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation and security selection within Investment Grade Credit, particularly in the Financials and Industrials sectors, were the main contributors to performance. The Fund’s allocation to Securitized sectors, including Asset-Backed Securities (ABS), Mortgage-Backed Securities (MBS), and Commercial Mortgage-Backed Securities (CMBS) contributed positively to relative returns and these sectors also outperformed duration-equivalent Treasuries during the period. Top Detractors to Performance While derivatives were not utilized in a significant manner in this Fund during the period, currency forwards were used to hedge the Fund's exposure to non-USD denominated securities, which detracted modestly from performance over the period. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024, as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the Bloomberg 1-3 Year US Government/Credit Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation and security selection within Investment Grade Credit, particularly in the Financials and Industrials sectors, were the main contributors to performance. The Fund’s allocation to Securitized sectors, including Asset-Backed Securities (ABS), Mortgage-Backed Securities (MBS), and Commercial Mortgage-Backed Securities (CMBS) contributed positively to relative returns and these sectors also outperformed duration-equivalent Treasuries during the period. Top Detractors to Performance While derivatives were not utilized in a significant manner in this Fund during the period, currency forwards were used to hedge the Fund's exposure to non-USD denominated securities, which detracted modestly from performance over the period. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results. |

Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Bloomberg US Aggregate Bond Index for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation to Structured Finance sectors had a positive impact on results. An allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) was a positive contributor to relative performance, as housing supply shortages continued to act as a tailwind. An overweight to agency mortgage backed securities Corporate credit positioning contributed positively to relative results overall. The Fund’s out-of-benchmark exposure to high yield aided results, led by industrials. Security selection within investment credit also benefited performance. The Fund held interest rate positions during the period, including interest rate futures and interest rate swaps as well as currency forwards to implement non-U.S. rate and currency positions; overall duration and yield curve positioning was the top positive contributor to relative results. Credit Default Swaps (CDX) were used to manage credit exposure and overall portfolio risk. High yield CDX positions helped results, while emerging market CDX and investment grade CDX had a neutral impact. Top Detractors to Performance The Fund’s allocation to Treasury Inflation Protected Securities (TIPS) detracted from relative results during the period. An overall underweight in investment grade corporates (industrials) detracted from relative performance.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Bloomberg US Aggregate Bond Index for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation to Structured Finance sectors had a positive impact on results. An allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) was a positive contributor to relative performance, as housing supply shortages continued to act as a tailwind. An overweight to agency mortgage backed securities Corporate credit positioning contributed positively to relative results overall. The Fund’s out-of-benchmark exposure to high yield aided results, led by industrials. Security selection within investment credit also benefited performance. The Fund held interest rate positions during the period, including interest rate futures and interest rate swaps as well as currency forwards to implement non-U.S. rate and currency positions; overall duration and yield curve positioning was the top positive contributor to relative results. Credit Default Swaps (CDX) were used to manage credit exposure and overall portfolio risk. High yield CDX positions helped results, while emerging market CDX and investment grade CDX had a neutral impact. Top Detractors to Performance The Fund’s allocation to Treasury Inflation Protected Securities (TIPS) detracted from relative results during the period. An overall underweight in investment grade corporates (industrials) detracted from relative performance. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Bloomberg US Aggregate Bond Index for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation to Structured Finance sectors had a positive impact on results. An allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) was a positive contributor to relative performance, as housing supply shortages continued to act as a tailwind. An overweight to agency mortgage backed securities Corporate credit positioning contributed positively to relative results overall. The Fund’s out-of-benchmark exposure to high yield aided results, led by industrials. Security selection within investment credit also benefited performance. The Fund held interest rate positions during the period, including interest rate futures and interest rate swaps as well as currency forwards to implement non-U.S. rate and currency positions; overall duration and yield curve positioning was the top positive contributor to relative results. Credit Default Swaps (CDX) were used to manage credit exposure and overall portfolio risk. High yield CDX positions helped results, while emerging market CDX and investment grade CDX had a neutral impact. Top Detractors to Performance The Fund’s allocation to Treasury Inflation Protected Securities (TIPS) detracted from relative results during the period. An overall underweight in investment grade corporates (industrials) detracted from relative performance. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance?

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Tax-exempt municipal bonds, Top Contributors to Performance Security selection within high-yield revenue bonds and investment-grade revenue bonds were the primary contributor to relative performance. Security selection within investment grade health care, utilities, special tax, port, airport and marina, were also additive. The Fund’s overweight duration positioning also contributed to relative results as the municipal bond curve rallied over the period. Top Detractors to Performance The primary detractor from the Fund’s relative performance was the Fund’s allocation to high yield revenue bonds as the sector underperformed duration equivalent treasuries. Underweights to investment-grade GO bonds, both state and local, also detracted from relative performance. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Bloomberg US Aggregate Bond Index for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s out-of-benchmark allocation to High Yield Credit was the top positive contributor to relative performance, led by allocations High Yield Credit in the Industrials and Financials sectors. An allocation to Bank Loans in the Industrials sector, and an allocation to select convertible bonds also aided results. The Fund’s allocation to structured finance had a positive impact on results. The Fund’s allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) was a positive contributor to relative performance. Exposure to other securitized sectors including Commercial Mortgage-Backed Securities (CMBS), Collateralized Loan Obligations (CLOs), and Asset-Backed Securities (ABS) contributed positively to relative performance. The Fund’s exposure Emerging Markets (EM) debt, both EM Corporate and to a lesser extent select EM Sovereign Debt, contributed positively to performance. During the period, the Fund used credit default swaps to help implement the overall investment strategy, which in the aggregate contributed positively to relative results. Top Detractors to Performance The Fund’s underweight positioning within Investment Grade Credit detracted from relative performance. An underweight to agency Mortgage-Backed Securities passthroughs also detracted from performance. The Fund’s allocation to Treasury Inflation Protected Securities (TIPS) detracted from relative results during the period. During the period, the Fund also used interest rate swaps, currency forwards and futures to help implement the overall investment strategy, which in the aggregate detracted from relative results.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Bloomberg US Aggregate Bond Index for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s out-of-benchmark allocation to High Yield Credit was the top positive contributor to relative performance, led by allocations High Yield Credit in the Industrials and Financials sectors. An allocation to Bank Loans in the Industrials sector, and an allocation to select convertible bonds also aided results. The Fund’s allocation to structured finance had a positive impact on results. The Fund’s allocation to Non-Agency Residential Mortgage-Backed Securities (RMBS) was a positive contributor to relative performance. Exposure to other securitized sectors including Commercial Mortgage-Backed Securities (CMBS), Collateralized Loan Obligations (CLOs), and Asset-Backed Securities (ABS) contributed positively to relative performance. The Fund’s exposure Emerging Markets (EM) debt, both EM Corporate and to a lesser extent select EM Sovereign Debt, contributed positively to performance. During the period, the Fund used credit default swaps to help implement the overall investment strategy, which in the aggregate contributed positively to relative results. Top Detractors to Performance The Fund’s underweight positioning within Investment Grade Credit detracted from relative performance. An underweight to agency Mortgage-Backed Securities passthroughs also detracted from performance. The Fund’s allocation to Treasury Inflation Protected Securities (TIPS) detracted from relative results during the period. During the period, the Fund also used interest rate swaps, currency forwards and futures to help implement the overall investment strategy, which in the aggregate detracted from relative results.

Management's Discussion of Fund Performance International equities, as measured by the MSCI ACWI ex USA Index (Net), rose over the trailing twelve-month period ending October 31, 2024, supported by easing inflation and interest rate cuts. Despite mixed economic indicators and geopolitical tensions, such as leadership changes in major countries and conflict in the Middle East, resilient labor markets and lower energy prices bolstered market sentiment. Fund performance described below is relative to the MSCI ACWI ex USA Index (Net) for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection within the Communication Services, Information Technology, and Consumer Discretionary sectors contributed positively to relative performance. The Fund’s exposure to what we consider to be higher quality companies contributed to relative results. Top individual contributors over the period were out-of-benchmark positions in Spotify Technology (Communication Services) and ARM (Information Technology), as well as an overweight position in Taiwan Semiconductor (Information Technology). Top Detractors to Performance Sector allocation, a result of our bottom-up stock selection process, was the primary detractor to relative performance during the period due to the Fund’s underweight allocation to the Financials sector and overweight allocations to the Consumer Staples and Information Technology sectors. Security selection was also a detractor to relative performance during the period, driven by weak selection within the Industrials, Financials, and Energy sectors. From a style perspective, the Fund’s exposure to lower-beta names detracted from relative performance. Beta is a measure of risk that indicates the price sensitivity of a security or a portfolio relative to a specified market index. The largest individual detractors over the period were overweight positions in Heineken (Consumer Staples) and Davide Campari-Milan (Consumer Staples), as well as an out-of-benchmark position in Lululemon Athletica (Consumer Discretionary).

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance International equities, as measured by the MSCI ACWI ex USA Index (Net), rose over the trailing twelve-month period ending October 31, 2024, supported by easing inflation and interest rate cuts. Despite mixed economic indicators and geopolitical tensions, such as leadership changes in major countries and conflict in the Middle East, resilient labor markets and lower energy prices bolstered market sentiment. Fund performance described below is relative to the MSCI ACWI ex USA Index (Net) for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection within the Communication Services, Information Technology, and Consumer Discretionary sectors contributed positively to relative performance. The Fund’s exposure to what we consider to be higher quality companies contributed to relative results. Top individual contributors over the period were out-of-benchmark positions in Spotify Technology (Communication Services) and ARM (Information Technology), as well as an overweight position in Taiwan Semiconductor (Information Technology). Top Detractors to Performance Sector allocation, a result of our bottom-up stock selection process, was the primary detractor to relative performance during the period due to the Fund’s underweight allocation to the Financials sector and overweight allocations to the Consumer Staples and Information Technology sectors. Security selection was also a detractor to relative performance during the period, driven by weak selection within the Industrials, Financials, and Energy sectors. From a style perspective, the Fund’s exposure to lower-beta names detracted from relative performance. Beta is a measure of risk that indicates the price sensitivity of a security or a portfolio relative to a specified market index. The largest individual detractors over the period were overweight positions in Heineken (Consumer Staples) and Davide Campari-Milan (Consumer Staples), as well as an out-of-benchmark position in Lululemon Athletica (Consumer Discretionary).

Management's Discussion of Fund Performance International equities rose over the trailing twelve-month period ending October 31, 2024, as measured by the MSCI ACWI ex USA Index (Net). In the period, heightened market volatility coincided with notable central bank policy decisions, major political developments, and an escalating conflict in the Middle East. Lower energy prices helped to ease inflationary pressures, and resilient labor markets in the United States, Europe, and Japan reinforced the view that the global economy could achieve a soft landing. Fund performance described below is relative to the Fund’s performance index, the MSCI EAFE Value Index (Net), for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection contributed to relative results during the period, mainly driven by selection within the Materials, Consumer Discretionary, and Energy sectors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance International equities rose over the trailing twelve-month period ending October 31, 2024, as measured by the MSCI ACWI ex USA Index (Net). In the period, heightened market volatility coincided with notable central bank policy decisions, major political developments, and an escalating conflict in the Middle East. Lower energy prices helped to ease inflationary pressures, and resilient labor markets in the United States, Europe, and Japan reinforced the view that the global economy could achieve a soft landing. Fund performance described below is relative to the Fund’s performance index, the MSCI EAFE Value Index (Net), for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection contributed to relative results during the period, mainly driven by selection within the Materials, Consumer Discretionary, and Energy sectors. Underweight allocation to the Utilities sector, overweight allocation to the Information Technology sector, and underweight allocation to the Healthcare sector contributed to relative performance. Top individual contributors over the period were an overweight position in UniCredit (Financials) as well as an out-of-benchmark positions in KB Financial Group (Financials) and BPER Banca (Financials). Top Detractors to Performance Security selection within the Industrials, Healthcare, and Communication Services sectors detracted from relative performance. Sector allocation, a result of the Fund’s bottom-up stock selection process, detracted from relative performance. This was due to the Fund’s overweight allocation to the Consumer Discretionary sector and underweight to the Financials sector. The largest individual detractors over the period were an overweight position in GSK (Healthcare) as well as out-of-benchmark positions in Yamato Holdings (Industrials) and Burberry Group (Consumer Discretionary). Derivatives were not used in a significant manner in the Fund during the period and did not have a material impact on performance during the period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance International equities rose over the trailing twelve-month period ending October 31, 2024, as measured by the MSCI ACWI ex USA Index (Net). In the period, heightened market volatility coincided with notable central bank policy decisions, major political developments, and an escalating conflict in the Middle East. Lower energy prices helped to ease inflationary pressures, and resilient labor markets in the United States, Europe, and Japan reinforced the view that the global economy could achieve a soft landing. Fund performance described below is relative to the Fund’s performance index, the MSCI EAFE Value Index (Net), for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection contributed to relative results during the period, mainly driven by selection within the Materials, Consumer Discretionary, and Energy sectors. Underweight allocation to the Utilities sector, overweight allocation to the Information Technology sector, and underweight allocation to the Healthcare sector contributed to relative performance. Top individual contributors over the period were an overweight position in UniCredit (Financials) as well as an out-of-benchmark positions in KB Financial Group (Financials) and BPER Banca (Financials). Top Detractors to Performance Security selection within the Industrials, Healthcare, and Communication Services sectors detracted from relative performance. Sector allocation, a result of the Fund’s bottom-up stock selection process, detracted from relative performance. This was due to the Fund’s overweight allocation to the Consumer Discretionary sector and underweight to the Financials sector. The largest individual detractors over the period were an overweight position in GSK (Healthcare) as well as out-of-benchmark positions in Yamato Holdings (Industrials) and Burberry Group (Consumer Discretionary). Derivatives were not used in a significant manner in the Fund during the period and did not have a material impact on performance during the period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance During the trailing twelve-month period ended October 31, 2024, emerging local markets debt had positive returns, as measured by the JP Morgan GBI Emerging Markets Global Diversified Index. Within the JP Morgan GBI Emerging Markets Global Diversified Index, Emerging Markets (EM) currencies depreciated, while EM rates had positive impact. Middle East/Africa was the best-performing region in the JP Morgan GBI Emerging Markets Global Diversified Index. Fund performance described below is relative to the Fund’s performance index, JP Morgan GBI Emerging Markets Global Diversified Index, for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance An out-of-benchmark allocation to external corporate debt in Turkey, Mexico and Peru contributed to relative performance. The Fund’s tactical duration and yield curve positioning was a positive contributor to the Fund’s relative performance over the period. Top Detractors to Performance The Fund’s underweight to the local sovereign debt in Thailand and Indonesia detracted from relative performance. The Fund’s underweights to the short- and mid-dated local sovereign debt in South Africa detracted from relative performance. During the period, the Fund’s use of derivatives was additive to relative performance. The Fund’s interest rate and credit positioning were primarily implemented through cash bond positions and derivatives such as interest rate and total return swaps, credit default swap contracts, and interest rate futures. The investment team used local currency denominated cash bonds, currency forwards (deliverable and non-deliverable), and currency options to express their views on currency.

The Fund’s tactical duration and yield curve positioning was a positive contributor to the Fund’s relative performance over the period. Top Detractors to Performance The Fund’s underweight to the local sovereign debt in Thailand and Indonesia detracted from relative performance. The Fund’s underweights to the short- and mid-dated local sovereign debt in South Africa detracted from relative performance. During the period, the Fund’s use of derivatives was additive to relative performance. The Fund’s interest rate and credit positioning were primarily implemented through cash bond positions and derivatives such as interest rate and total return swaps, credit default swap contracts, and interest rate futures. The investment team used local currency denominated cash bonds, currency forwards (deliverable and non-deliverable), and currency options to express their views on currency. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Emerging Markets equities rose over the trailing twelve-month period ending October 31, 2024, as measured by the MSCI Emerging Markets Index (Net). In the period, heightened market volatility coincided with notable central bank policy decisions, major political developments, and an escalating conflict in the Middle East. Lower energy prices helped to ease inflationary pressures, and resilient labor markets in the United States, Europe, and Japan reinforced the view that the global economy could achieve a soft landing. Fund performance described below is relative to the MSCI Emerging Markets Index (Net), for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection was the primary contributor to relative performance during the period, driven by strong selection within the Financials, Industrials, and Consumer Staples sectors. Top individual contributors over the period were out-of-benchmark allocation to International Games System (Communication Services) and overweight positions in Power Finance Corporation (Financials) and JD.com (Consumer Discretionary). The Fund’s underweight allocation to the Energy and Materials sectors contributed to relative performance. Top Detractors to Performance Security selection within the Communication Services and Utilities sectors detracted from relative performance. The largest individual detractors over the period were an underweight position in Hon Hai Precision Industry (Information Technology), an overweight position in NAVER (Communication Services) and an out-of-benchmark allocation to PTT Exploration and Production (Energy). Sector allocation, a result of our quantitative security selection process, was a detractor to relative performance during the period due to the Fund’s underweight allocations to the Information Technology and Communication Services sectors.

Top Contributors to Performance Security selection was the primary contributor to relative performance during the period, driven by strong selection within the Financials, Industrials, and Consumer Staples sectors. Top individual contributors over the period were out-of-benchmark allocation to International Games System (Communication Services) and overweight positions in Power Finance Corporation (Financials) and JD.com (Consumer Discretionary). The Fund’s underweight allocation to the Energy and Materials sectors contributed to relative performance. Top Detractors to Performance Security selection within the Communication Services and Utilities sectors detracted from relative performance. The largest individual detractors over the period were an underweight position in Hon Hai Precision Industry (Information Technology), an overweight position in NAVER (Communication Services) and an out-of-benchmark allocation to PTT Exploration and Production (Energy). Sector allocation, a result of our quantitative security selection process, was a detractor to relative performance during the period due to the Fund’s underweight allocations to the Information Technology and Communication Services sectors.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Top Contributors to Performance The Fund’s strategic duration strategy had a positive impact on total returns. The Fund’s long duration positioning to the developed countries contributed, as most of the developed sovereign yields moved broadly lower during the period causing the prices of such sovereign debt to broadly move The Fund's credit strategies also contributed to total returns. In opportunistic credit strategies, the Fund’s net long exposure to investment grade (IG) corporate issuers, higher yield (HY), emerging market debts and selection securitized sector contributed. During the period, major global central banks began to cut short-term interest rates as they shifted priorities towards avoiding a spike in unemployment rates.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Top Contributors to Performance The Fund’s strategic duration strategy had a positive impact on total returns. The Fund’s long duration positioning to the developed countries contributed, as most of the developed sovereign yields moved broadly lower during the period causing the prices of such sovereign debt to broadly move The Fund's credit strategies also contributed to total returns. In opportunistic credit strategies, the Fund’s net long exposure to investment grade (IG) corporate issuers, higher yield (HY), emerging market debts and selection securitized sector contributed. During the period, major global central banks began to cut short-term interest rates as they shifted priorities towards avoiding a spike in unemployment rates. Top Detractors to Performance The Fund's opportunistic rates strategies were negative. The Fund’s Japanese Government Bond (JGB) flattener position detracted, as the Japanese yield curve steepened in sympathy with global rates markets.

During the period, major global central banks began to cut short-term interest rates as they shifted priorities towards avoiding a spike in unemployment rates. Top Detractors to Performance The Fund's opportunistic rates strategies were negative. The Fund’s Japanese Government Bond (JGB) flattener position detracted, as the Japanese yield curve steepened in sympathy with global rates markets. During the period, the Fund used derivatives, such as liquid currency forwards and exchange-traded government bond futures, and in small part, credit default swaps, index credit default swaps, as well as interest rate, bond, index and currency futures, and/or options, in pursuit of the investment objective as well as to hedge against risk. Overall, these derivatives detracted from performance during the period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Effective March 1, 2024, the Fund (formerly known as The Hartford Floating Rate High Income Fund) changed its name, objective, principal investment strategy, portfolio managers and benchmark. The commentary covers the period of March 1, 2024 through October 31, 2024. United States (U.S.) fixed income sectors generated positive total returns during the trailing eight-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Fund’s performance index, the ICE BofA 1-3 Year BB-B US Cash Pay High Yield Index, for the trailing eight-month period ended October 31, 2024. Top Contributors to Performance The Fund’s allocation to Structured Finance sectors had a positive impact on relative performance. The Fund’s allocation to Asset Backed Securities (ABS), allocated primarily to Collateralized Loan Obligations (CLOs) was a strong contributor during the period. Exposure to other The Fund’s allocation to Bank Loans also contributed positively to returns over the period. The Fund’s allocation to Investment Grade Credit was a contributor over the period, driven by positioning within the Financials and Industrials sectors. Top Detractors to Performance The Fund maintained a short duration position during the period while yields fell which detracted from performance. The Fund’s allocation to High Yield Credit was a detractor during the period, driven by positioning within the Industrials and Financials sectors. The Fund used derivatives on a limited basis during the period for risk management purposes. Overall, the use of derivatives detracted from relative performance during the period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Tax-exempt municipal bonds, as represented by the Bloomberg Municipal Bond 1-15 Year Blend (1-17) Index, generated a positive total return during the trailing twelve-month period ended October 31, 2024. This index outperformed duration-equivalent Treasuries over the same period. The yield on 10-year AAA-rated general obligation municipal bonds (GOs) decreased during the twelve-month period ended October 31, 2024, as did the yield on 10-year Treasuries. Fund performance described below is relative to the Top Contributors to Performance Security selection within high-yield revenue bonds was the primary driver of relative performance, particularly in healthcare and sales tax. Security selection within investment-grade revenue bonds was also additive, specifically in healthcare, education, and utilities. The Fund’s overweight duration positioning contributed modestly to relative results as the municipal bond curve rallied over the period. Top Detractors to Performance The primary detractor from relative performance was the Fund’s overweight allocation to high-yield revenue bonds as the sector underperformed duration equivalent treasuries. The Fund’s underweight positions to investment-grade GO bonds, both state and local, also detracted from relative performance. We believe it is difficult to quantify the impact of sustainability considerations on the Fund’s performance given the slow-moving nature of certain ESG risks.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Tax-exempt municipal bonds, as represented by the Bloomberg Municipal Bond 1-15 Year Blend (1-17) Index, generated a positive total return during the trailing twelve-month period ended October 31, 2024. This index outperformed duration-equivalent Treasuries over the same period. The yield on 10-year AAA-rated general obligation municipal bonds (GOs) decreased during the twelve-month period ended October 31, 2024, as did the yield on 10-year Treasuries. Fund performance described below is relative to the Top Contributors to Performance Security selection within high-yield revenue bonds was the primary driver of relative performance, particularly in healthcare and sales tax. Security selection within investment-grade revenue bonds was also additive, specifically in healthcare, education, and utilities. The Fund’s overweight duration positioning contributed modestly to relative results as the municipal bond curve rallied over the period. Top Detractors to Performance The primary detractor from relative performance was the Fund’s overweight allocation to high-yield revenue bonds as the sector underperformed duration equivalent treasuries. The Fund’s underweight positions to investment-grade GO bonds, both state and local, also detracted from relative performance. We believe it is difficult to quantify the impact of sustainability considerations on the Fund’s performance given the slow-moving nature of certain ESG risks. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Global equities, as measured by the Top Contributors to Performance Security selection within the Industrials sector was the primary contributor to relative returns during the period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Global equities, as measured by the Top Contributors to Performance Security selection within the Industrials sector was the primary contributor to relative returns during the period. Sector allocation was also positive with strength within the Industrials, Health Care, and Energy sectors. Top relative individual contributors over the period were an overweight position in Vertiv Holdings (Industrials), an out-of-benchmark allocation to Acuity Brands (Industrials) and ARM Holdings (Industrials), and an overweight position in Westinghouse Air Brake Technologies (Industrials). Top Detractors to Performance Security selection detracted from relative performance during the period, driven by selection within the Information Technology, Utilities, Consumer Discretionary and Financials sectors. Sector allocation also detracted from results within the Information Technology, Financials, and Communication Services sectors. The largest individual relative detractors over the period were not owning benchmark constituent NVIDIA (Information Technology), owning Vestas Wind Systems (Industrials) and overweight positions in Enphase Energy (Information Technology) and Samsung SDI C. (Information Technology).

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Global equities, as measured by the MSCI ACWI Index (Net), rose over the trailing twelve-month period ending October 31, 2024, supported by easing inflation and interest rate cuts. Despite mixed economic indicators and geopolitical tensions, such as leadership changes in major countries and conflict in the Middle East, resilient labor markets and lower energy prices bolstered market sentiment. Fund performance described below is relative to the MSCI ACWI Index (Net) for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection was the primary contributor to relative performance during the period, driven by strong selection within the Industrials, Consumer Discretionary, and Materials sectors. Top relative individual contributors over the period were overweight positions in GoDaddy (Information Technology), Trane Technologies (Industrials) and Westinghouse Air Brake Technologies (Industrials). Top Detractors to Performance Security selection within the Financials, Communication Services, and Information Technology sectors detracted from relative performance. The largest individual relative detractors over the period were not owning NVIDIA (Information Technology) and overweight positions in Agilon Health (Healthcare) and Globe Life (Financials). Sector allocation, a result of our bottom-up stock selection process, was a detractor to relative performance during the period due to the Fund’s overweight allocation to the Healthcare sector and underweight to the Information Technology sector.

Top Contributors to Performance Security selection was the primary contributor to relative performance during the period, driven by strong selection within the Industrials, Consumer Discretionary, and Materials sectors. Top relative individual contributors over the period were overweight positions in GoDaddy (Information Technology), Trane Technologies (Industrials) and Westinghouse Air Brake Technologies (Industrials). Top Detractors to Performance Security selection within the Financials, Communication Services, and Information Technology sectors detracted from relative performance. The largest individual relative detractors over the period were not owning NVIDIA (Information Technology) and overweight positions in Agilon Health (Healthcare) and Globe Life (Financials). Sector allocation, a result of our bottom-up stock selection process, was a detractor to relative performance during the period due to the Fund’s overweight allocation to the Healthcare sector and underweight to the Information Technology sector.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance Global equities, as measured by the MSCI ACWI Index (Net), rose over the trailing twelve-month period ending October 31, 2024, supported by easing inflation and interest rate cuts. Despite mixed economic indicators and geopolitical tensions, such as leadership changes in major countries and conflict in the Middle East, resilient labor markets and lower energy prices bolstered market sentiment. Fund performance described below is relative to the MSCI ACWI Index (Net) for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance Security selection was the primary contributor to relative performance during the period, driven by strong selection within the Industrials, Consumer Discretionary, and Materials sectors. Top relative individual contributors over the period were overweight positions in GoDaddy (Information Technology), Trane Technologies (Industrials) and Westinghouse Air Brake Technologies (Industrials). Top Detractors to Performance Security selection within the Financials, Communication Services, and Information Technology sectors detracted from relative performance. The largest individual relative detractors over the period were not owning NVIDIA (Information Technology) and overweight positions in Agilon Health (Healthcare) and Globe Life (Financials). Sector allocation, a result of our bottom-up stock selection process, was a detractor to relative performance during the period due to the Fund’s overweight allocation to the Healthcare sector and underweight to the Information Technology sector.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended October 31, 2024 as measured by the Bloomberg US Aggregate Bond Index. U.S. Treasury yields ended broadly lower, geopolitical uncertainty rose in Europe and the Middle East, and major banks’ monetary policy paths diverged. Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Bloomberg US Aggregate Bond Index for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s security selection and overweight allocation to both investment grade credit and high yield credit were the primary contributors to the Fund’s relative performance. These sectors broadly saw positive performance relative to duration-equivalent Treasuries during the trailing twelve months as spreads tightened. The Fund’s overweight to and security selection in emerging market corporate and government-related credit positively contributed as well. During the period, the Fund employed the tactical use of credit default index swaps to hedge exposure and gain liquid exposure to credit risk, which contributed to relative performance. Top Detractors to Performance The Fund’s duration and yield curve positioning detracted from relative performance over the trailing twelve months, as the Fund was positioned with a lower duration posture than the benchmark over the period. Additionally, the Fund did not hold any mortgage-backed securities or commercial mortgage-backed securities which detracted from relative performance. During the period, the Fund employed the tactical use of interest rate futures to hedge exposure and gain liquid exposure to credit risk, which modestly detracted from relative performance. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.

Most spread sectors generated positive excess returns over duration-equivalent government bonds as spreads narrowed, supported by more accommodative central bank policies. Fund performance described below is relative to the Bloomberg US Aggregate Bond Index for the trailing twelve-month period ended October 31, 2024. Top Contributors to Performance The Fund’s security selection and overweight allocation to both investment grade credit and high yield credit were the primary contributors to the Fund’s relative performance. These sectors broadly saw positive performance relative to duration-equivalent Treasuries during the trailing twelve months as spreads tightened. The Fund’s overweight to and security selection in emerging market corporate and government-related credit positively contributed as well. During the period, the Fund employed the tactical use of credit default index swaps to hedge exposure and gain liquid exposure to credit risk, which contributed to relative performance. Top Detractors to Performance The Fund’s duration and yield curve positioning detracted from relative performance over the trailing twelve months, as the Fund was positioned with a lower duration posture than the benchmark over the period. Additionally, the Fund did not hold any mortgage-backed securities or commercial mortgage-backed securities which detracted from relative performance. During the period, the Fund employed the tactical use of interest rate futures to hedge exposure and gain liquid exposure to credit risk, which modestly detracted from relative performance. The views expressed in this section reflect the opinions of the Fund's sub-adviser, Wellington Management Company LLP, as of the date of this report and are subject to change based on changes in market, economic or other conditions.
