| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the FTSE World Government Bond Index (the Index): ↑ An out-of-Index allocation to the Serbian dinar, which strengthened amid government reforms and a positive economic growth outlook for Serbia, contributed to returns relative to the Index during the period ↑ An overweight exposure to the euro helped Index-relative performance, as the euro rallied on expectations of aggressive monetary policy easing in the U.S. ↑ An out-of-Index allocation to the Icelandic krona, which strengthened alongside high interest rates in Iceland, contributed to Index-relative returns ↑ The use of derivatives — led by interest-rate swaps to manage interest-rate exposures — contributed to performance relative to the Index during the period ↓ A short position in the South African rand detracted from Index-relative returns, as the rand strengthened following the results of national elections ↓ An overweight exposure to the Japanese yen, which weakened to a multi-decade low versus the U.S. dollar, detracted from Index-relative performance ↓ An overweight exposure to Polish interest rates hurt Index-relative returns as Poland’s central bank held rates steady while many other central banks cut rates | |

Key contributors to (↑) and detractors from (↓) performance, relative to the FTSE World Government Bond Index (the Index): ↑ An out-of-Index allocation to the Serbian dinar, which strengthened amid government reforms and a positive economic growth outlook for Serbia, contributed to returns relative to the Index during the period ↑ An overweight exposure to the euro helped Index-relative performance, as the euro rallied on expectations of aggressive monetary policy easing in the U.S. ↑ An out-of-Index allocation to the Icelandic krona, which strengthened alongside high interest rates in Iceland, contributed to Index-relative returns ↑ The use of derivatives — led by interest-rate swaps to manage interest-rate exposures — contributed to performance relative to the Index during the period ↓ A short position in the South African rand detracted from Index-relative returns, as the rand strengthened following the results of national elections ↓ An overweight exposure to the Japanese yen, which weakened to a multi-decade low versus the U.S. dollar, detracted from Index-relative performance ↓ An overweight exposure to Polish interest rates hurt Index-relative returns as Poland’s central bank held rates steady while many other central banks cut rates | |

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

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) absolute performance: ↑ A long exposure to Surinamese sovereign credit contributed to performance following a debt restructuring that significantly reduced debt service obligations ↑ A long exposure to Egyptian local bonds contributed to returns during a period marked by positive reforms, International Monetary Fund (IMF) support, and regional support amid the Israel-Hamas conflict ↑ A long exposure to Uzbekistani local bonds, which benefited from perceptions of strengthening political institutions, contributed to returns during the period ↓ In contrast, a short exposure to South African sovereign credit detracted from returns as national elections resulted in a new coalition government expected to focus on structural reforms that may increase economic growth in South Africa ↓ Optimism about South Africa’s new government caused the South African rand to strengthen, and a short position in the currency detracted from performance ↓ Derivatives — led by credit-default swaps used to manage credit exposures and foreign exchange forwards used to manage currency exposures — hurt returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) absolute performance: ↑ A long exposure to Surinamese sovereign credit contributed to performance following a debt restructuring that significantly reduced debt service obligations ↑ A long exposure to Egyptian local bonds contributed to returns during a period marked by positive reforms, International Monetary Fund (IMF) support, and regional support amid the Israel-Hamas conflict ↑ A long exposure to Uzbekistani local bonds, which benefited from perceptions of strengthening political institutions, contributed to returns during the period ↓ In contrast, a short exposure to South African sovereign credit detracted from returns as national elections resulted in a new coalition government expected to focus on structural reforms that may increase economic growth in South Africa ↓ Optimism about South Africa’s new government caused the South African rand to strengthen, and a short position in the currency detracted from performance ↓ Derivatives — led by credit-default swaps used to manage credit exposures and foreign exchange forwards used to manage currency exposures — hurt returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) absolute performance: ↑ A long exposure to Surinamese sovereign credit contributed to performance following a debt restructuring that significantly reduced debt service obligations ↑ A long exposure to Egyptian local bonds contributed to returns during a period marked by positive reforms, International Monetary Fund (IMF) support, and regional support amid the Israel-Hamas conflict ↑ A long exposure to Uzbekistani local bonds, which benefited from perceptions of strengthening political institutions, contributed to returns during the period ↓ In contrast, a short exposure to South African sovereign credit detracted from returns as national elections resulted in a new coalition government expected to focus on structural reforms that may increase economic growth in South Africa ↓ Optimism about South Africa’s new government caused the South African rand to strengthen, and a short position in the currency detracted from performance ↓ Derivatives — led by credit-default swaps used to manage credit exposures and foreign exchange forwards used to manage currency exposures — hurt returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the ICE BofA 1-3 Year U.S. Treasury Index (11/1/23-12/31/23) and the ICE BofA U.S. Mortgage Backed Securities Index (1/1/24-10/31/24) (the Index): ↑ Out-of-Index exposures to agency collateralized mortgage obligations (CMOs) contributed to performance relative to the Index during the period ↑ Out-of-Index exposures to non-agency mortgage-backed securities (MBS) contributed to performance relative to the Index during the period ↑ Security selections within fixed-rate agency mortgage-backed securities (MBS) pass-throughs contributed to performance relative to the Index during the period ↑ Duration positioning ― which was longer than that of the Index ― contributed to returns relative to the Index during a period when interest rates generally declined ↓ The Fund’s out-of-Index use of derivatives for duration management ― by investing in interest-rate swaps; U.S. Treasury futures; and swap options, or swaptions ― detracted from returns relative to the Index during the period | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg U.S. Aggregate Bond Index (the Index): ↑ Out-of-Index exposures to emerging-market debt ― both USD-denominated and local currency-denominated bonds ― contributed to returns relative to the Index ↑ Out-of-Index exposures to high yield corporate bonds and non-agency mortgage-backed securities (MBS) contributed to performance relative to the Index during the period ↑ The Fund’s out-of-Index use of derivatives for duration management ― by investing in U.S. Treasury futures and interest-rate swaps ― contributed to returns relative to the Index during the period ↓ The Fund’s out-of-Index allocation to bank loans and exposure to the Eaton Vance Global Macro Absolute Return Advantage Fund strategy detracted from returns relative to the Index during the period ↓ Duration positioning ― which was shorter than that of the Index ― detracted from returns relative to the Index during a period when interest rates declined | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI Emerging Markets Equal Country Weighted Index (the Index): ↑ An overweight exposure to Greek equities — which benefited from business-friendly labor and judicial reforms — contributed to Index-relative performance ↑ An overweight exposure to South Korean equities contributed to Index-relative returns amid strong political movement toward market reforms. However, after parliamentary elections raised concerns about the support for such reform measures, the Fund sold its position in South Korean stocks ↑ An out-of-Index exposure to Vietnamese equities ― which benefited from Vietnam’s growing standing as an option to Chinese manufacturing ― aided returns ↓ An underweight exposure to Chinese equities hurt relative returns. Although Chinese stocks performed poorly during much of the period, they rallied sharply in September 2024 after the government announced new economic stimulus measures ↓ An underweight exposure to Peruvian stocks, which were sold by period-end, hurt returns as the country’s economic growth and stock prices recovered in 2024 ↓ An underweight exposure to South African equities hurt returns as markets rallied after presidential election results were viewed as positive for investors | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI Emerging Markets Equal Country Weighted Index (the Index): ↑ An overweight exposure to Greek equities — which benefited from business-friendly labor and judicial reforms — contributed to Index-relative performance ↑ An overweight exposure to South Korean equities contributed to Index-relative returns amid strong political movement toward market reforms. However, after parliamentary elections raised concerns about the support for such reform measures, the Fund sold its position in South Korean stocks ↑ An out-of-Index exposure to Vietnamese equities ― which benefited from Vietnam’s growing standing as an option to Chinese manufacturing ― aided returns ↓ An underweight exposure to Chinese equities hurt relative returns. Although Chinese stocks performed poorly during much of the period, they rallied sharply in September 2024 after the government announced new economic stimulus measures ↓ An underweight exposure to Peruvian stocks, which were sold by period-end, hurt returns as the country’s economic growth and stock prices recovered in 2024 ↓ An underweight exposure to South African equities hurt returns as markets rallied after presidential election results were viewed as positive for investors | |

For more complete information, you may review the Fund’s next prospectus, which we expect to be available by March 1, 2025 at www.eatonvance.com/open-end-mutual-fund-documents.php Prior to March 1, 2024, the investment adviser had agreed to reimburse the Fund's expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only and excluding expenses such as brokerage commissions, acquired fund fees and expenses of unaffiliated funds, borrowing costs (including borrowing costs of any acquired funds), taxes or litigation expenses) exceeded 1.15% of the Fund's average daily net assets for Class A. This agreement expired on March 1, 2024. The net expense ratio increased from the prior year primarily due to an increase in interest expense and fees related to short sales and financing activities. | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the J.P. Morgan Government Bond Index: Emerging Markets (JPM GBI-EM) Global Diversified (Unhedged) (the Index): ↑ An out-of-Index allocation to Egyptian local currency bonds contributed to the Fund’s performance relative to the Index during a period of positive reforms, assistance from the International Monetary Fund (IMF), and regional support amid the Israel-Hamas conflict ↑ An overweight exposure to the Turkish lira helped relative returns after local elections resulted in the continuation of Turkey’s more orthodox monetary policy ↑ An out-of-Index Kenyan shilling allocation ― sold by period-end ― aided returns after Kenya’s central bank raised interest rates and an IMF loan was approved ↑ Derivatives — led by foreign exchange forwards to manage currency exposures and interest-rate swaps to manage interest-rate exposures — helped Fund returns ↓ An underweight exposure to the South African rand, which strengthened following national elections, detracted from Index-relative returns during the period ↓ An underweight exposure to the Thai baht detracted from Index-relative returns, as the currency rallied with the broader market during most of the period ↓ An underweight exposure to the Chinese yuan, which strengthened in value after China announced economic stimulus measures, detracted from relative returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI World Index (the Index): ↓ The Fund’s common stock portfolio underperformed the Index and detracted from Index-relative returns during the period ↓ On an individual stock basis, the largest detractor from relative returns was an underweight position in NVIDIA Corp. ― the leading supplier of graphics processing unit microchips that help power the artificial intelligence boom ― whose stock price quadrupled on strong earnings and profits during the period ↓ Among sectors, stock selections and an underweight position in information technology, and stock selections in consumer discretionary hurt relative returns ↓ The use of equity index futures contracts — a type of derivative — detracted from Index-relative returns. The Fund’s strategy of emphasizing dividend-paying stocks resulted in an overweight exposure to European equities and an underweight exposure to U.S. equities, both of which were hedged with futures contracts ↑ The Fund’s out-of-Index position in Taiwan Semiconductor Manufacturing Co. doubled in price on surging demand for high-end microchips powering AI applications ↑ Among sectors, stock selections and an overweight position in the industrials sector, and stock selections in the health care sector helped relative returns | |

Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI World Index (the Index): ↓ The Fund’s common stock portfolio underperformed the Index and detracted from Index-relative returns during the period ↓ On an individual stock basis, the largest detractor from relative returns was an underweight position in NVIDIA Corp. ― the leading supplier of graphics processing unit microchips that help power the artificial intelligence boom ― whose stock price quadrupled on strong earnings and profits during the period ↓ Among sectors, stock selections and an underweight position in information technology, and stock selections in consumer discretionary hurt relative returns ↓ The use of equity index futures contracts — a type of derivative — detracted from Index-relative returns. The Fund’s strategy of emphasizing dividend-paying stocks resulted in an overweight exposure to European equities and an underweight exposure to U.S. equities, both of which were hedged with futures contracts ↑ The Fund’s out-of-Index position in Taiwan Semiconductor Manufacturing Co. doubled in price on surging demand for high-end microchips powering AI applications ↑ Among sectors, stock selections and an overweight position in the industrials sector, and stock selections in the health care sector helped relative returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI World Index (the Index). The Fund’s custom benchmark is 65% MSCI World Index / 35% ICE BofA Developed Markets High Yield Ex-Subordinated Financial Index (the ICE BofA Index) ↓ The Fund’s common stock portfolio underperformed the Index and detracted from Index-relative returns during the period ↓ The Fund’s high yield bond allocation lagged the Index ― as well as the high yield market, as measured by the ICE BofA Index ― during the period ↓ The Fund’s allocation to bank loans underperformed the Index and detracted from Index-relative returns during the period ↓ The Fund’s preferred securities allocation underperformed the Index and the preferred market, as measured by the ICE BofA Fixed-Rate Preferred Securities Index ↓ The use of equity index futures contracts — a type of derivative — detracted from Index-relative returns. The Fund’s strategy of emphasizing dividend-paying stocks resulted in an overweight exposure to European equities and an underweight exposure to U.S. equities, both of which were hedged with futures contracts ↑ Among sectors, stock selections and underweight exposures to health care and consumer discretionary, and stock selections in industrials, helped returns ↑ Currency forwards ― a hedging tool used to help mitigate exposure to varying foreign exchange rates ― contributed to performance relative to the Index | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI World Index (the Index). The Fund’s custom benchmark is 65% MSCI World Index / 35% ICE BofA Developed Markets High Yield Ex-Subordinated Financial Index (the ICE BofA Index) ↓ The Fund’s common stock portfolio underperformed the Index and detracted from Index-relative returns during the period ↓ The Fund’s high yield bond allocation lagged the Index ― as well as the high yield market, as measured by the ICE BofA Index ― during the period ↓ The Fund’s allocation to bank loans underperformed the Index and detracted from Index-relative returns during the period ↓ The Fund’s preferred securities allocation underperformed the Index and the preferred market, as measured by the ICE BofA Fixed-Rate Preferred Securities Index ↓ The use of equity index futures contracts — a type of derivative — detracted from Index-relative returns. The Fund’s strategy of emphasizing dividend-paying stocks resulted in an overweight exposure to European equities and an underweight exposure to U.S. equities, both of which were hedged with futures contracts ↑ Among sectors, stock selections and underweight exposures to health care and consumer discretionary, and stock selections in industrials, helped returns ↑ Currency forwards ― a hedging tool used to help mitigate exposure to varying foreign exchange rates ― contributed to performance relative to the Index | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) absolute performance: ↑ A long exposure to Egyptian local bonds contributed to returns during a period marked by positive reforms, International Monetary Fund (IMF) support, and regional support amid the Israel-Hamas conflict ↑ A long exposure to Surinamese sovereign credit contributed to performance following a debt restructuring that significantly reduced debt service obligations ↑ A long exposure to Uzbekistani local bonds, which benefited from perceptions of strengthening political institutions, contributed to returns during the period ↓ In contrast, a short exposure to South African sovereign credit detracted from returns as national elections resulted in a new coalition government expected to focus on structural reforms that may increase economic growth in South Africa ↓ Optimism about South Africa’s new government caused the South African rand to strengthen, and a short position in the currency detracted from performance ↓ Derivatives — led by credit-default swaps used to manage credit exposures and foreign exchange forwards used to manage currency exposures — hurt returns | |

Key contributors to (↑) and detractors from (↓) performance relative to the Fund’s Blended Index (the Index): ↓ Among Fund allocations to floating-rate loans, selections in the health care providers & services, and electronic equipment, instruments & components industries hurt returns ― the largest loan detractor being an overweight position in an appliance component manufacturer that entered Chapter 11 bankruptcy ↓ An underweight exposure to high yield bonds ― which outperformed the Index during the period ― detracted from returns relative to the Index ↓ During a period of strong performance by floating-rate loans and high yield bonds, the Fund’s modest cash position detracted from Index-relative returns ↑ An underweight exposure to floating-rate loans, which underperformed the Blended Index during the period, contributed to Fund returns versus the Index ↑ Out-of-Index exposures to collateralized loan obligations, mortgage-backed securities, commercial mortgage-backed securities, investment-grade corporate bonds, and emerging-market corporate bonds contributed to returns versus the Index during the period ↑ Within the Fund’s high yield bond allocation, selections in the diversified media, capital goods, and diversified financial services industries helped returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance relative to the Fund’s Blended Index (the Index): ↓ Among Fund allocations to floating-rate loans, selections in the health care providers & services, and electronic equipment, instruments & components industries hurt returns ― the largest loan detractor being an overweight position in an appliance component manufacturer that entered Chapter 11 bankruptcy ↓ An underweight exposure to high yield bonds ― which outperformed the Index during the period ― detracted from returns relative to the Index ↓ During a period of strong performance by floating-rate loans and high yield bonds, the Fund’s modest cash position detracted from Index-relative returns ↑ An underweight exposure to floating-rate loans, which underperformed the Blended Index during the period, contributed to Fund returns versus the Index ↑ Out-of-Index exposures to collateralized loan obligations, mortgage-backed securities, commercial mortgage-backed securities, investment-grade corporate bonds, and emerging-market corporate bonds contributed to returns versus the Index during the period ↑ Within the Fund’s high yield bond allocation, selections in the diversified media, capital goods, and diversified financial services industries helped returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance relative to the Fund’s Blended Index (the Index): ↓ Among Fund allocations to floating-rate loans, selections in the health care providers & services, and electronic equipment, instruments & components industries hurt returns ― the largest loan detractor being an overweight position in an appliance component manufacturer that entered Chapter 11 bankruptcy ↓ An underweight exposure to high yield bonds ― which outperformed the Index during the period ― detracted from returns relative to the Index ↓ During a period of strong performance by floating-rate loans and high yield bonds, the Fund’s modest cash position detracted from Index-relative returns ↑ An underweight exposure to floating-rate loans, which underperformed the Blended Index during the period, contributed to Fund returns versus the Index ↑ Out-of-Index exposures to collateralized loan obligations, mortgage-backed securities, commercial mortgage-backed securities, investment-grade corporate bonds, and emerging-market corporate bonds contributed to returns versus the Index during the period ↑ Within the Fund’s high yield bond allocation, selections in the diversified media, capital goods, and diversified financial services industries helped returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance relative to the Fund’s Blended Index (the Index): ↓ Among Fund allocations to floating-rate loans, selections in the health care providers & services, and electronic equipment, instruments & components industries hurt returns ― the largest loan detractor being an overweight position in an appliance component manufacturer that entered Chapter 11 bankruptcy ↓ An underweight exposure to high yield bonds ― which outperformed the Index during the period ― detracted from returns relative to the Index ↓ During a period of strong performance by floating-rate loans and high yield bonds, the Fund’s modest cash position detracted from Index-relative returns ↑ An underweight exposure to floating-rate loans, which underperformed the Blended Index during the period, contributed to Fund returns versus the Index ↑ Out-of-Index exposures to collateralized loan obligations, mortgage-backed securities, commercial mortgage-backed securities, investment-grade corporate bonds, and emerging-market corporate bonds contributed to returns versus the Index during the period ↑ Within the Fund’s high yield bond allocation, selections in the diversified media, capital goods, and diversified financial services industries helped returns | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI EAFE Index (the Index): ↓ Security selections in Japan ― particularly mid-cap and small-cap stocks in the real estate sector, which underperformed the Index ― detracted from returns ↓ Sector diversification in Japan hurt returns due, in part, to an underweight exposure to industrials, which rallied during a period of strong global demand ↓ Stock selections in Australia hampered performance, partly the result of excluding high beta stocks in the real estate sector, which outperformed the Index ↑ Diversification by country ― via a system of target country weights and systematically rebalancing them as they change ― contributed to Index-relative returns ↑ Country diversification ― the Fund held underweight exposures to larger countries and overweight exposures to smaller countries ― helped Index-relative returns ↑ Security selections in Sweden ― particularly small-cap stocks in the communication services sector, which performed well ― helped Index-relative returns ↑ Active sector allocations in Denmark helped performance, partly due to an overweight exposure to the materials sector, which performed well during the period ↑ Stock selections in Belgium ― particularly allocations to mid-cap and small-cap companies in the materials sector ― helped relative returns during the period | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 2000 ® ↓ A position in Chemed Corp., a hospice care and maintenance services provider, hurt Fund returns due to decreased revenue and earnings in its plumbing segment ↓ Not owning Super Micro Computer Inc., a server and data center equipment provider, hurt Fund returns as sales rose sharply on growth in artificial intelligence ↓ The Fund’s overweight position in U.S. Physical Therapy Inc., a physical therapy clinic operator, hampered relative returns as bad weather slowed its business ↓ An overweight position in property and casualty insurer Selective Insurance Group Inc. hampered returns after it reported a significant second-quarter loss ↑ An overweight position in Dorman Products Inc., a car parts maker, contributed to Index-relative returns during a period supported by strong earnings growth ↑ An overweight position in building products provider CSW Industrials Inc. helped returns as business efficiencies helped produce record revenues and earnings ↑ An allocation to Core & Main Inc. ― a storm drainage and fire protection equipment distributor ― helped returns on better-than-expected sales and earnings ↑ An overweight position in heating and air-conditioning equipment manufacturer AAON Inc. contributed to relative returns on strong revenue and earnings growth | |
