Aristotle/Saul Global Opportunities Fund

SUMMARY SECTION – Aristotle/Saul Global Opportunities Fund

Investment Objective

The investment objective of the Aristotle/Saul Global Opportunities Fund (the "Global Opportunities Fund") is to seek to maximize long-term capital appreciation and income.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Global Opportunities Fund.

Shareholder Fees
(fees paid directly from your investment)

Shareholder Fees	Aristotle/Saul Global Opportunities Fund Class I Shares USD ($)
Maximum sales charge (load) imposed on purchases	none
Maximum deferred sales charge (load)	none
Redemption fee if redeemed within 30 days of purchase (as a percentage of amount redeemed)	1.00%
Wire fee	$ 20
Overnight check delivery fee	25
Retirement account fees (annual maintenance fee)	$ 15

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Aristotle/Saul Global Opportunities Fund Class I Shares
Management fees	0.90%
Distribution (Rule 12b-1) fees	none
Other expenses	0.35%
Total annual fund operating expenses	1.25%
Fees waived and/or expenses reimbursed	(0.27%)
Total annual fund operating expenses after waiving fees and/or reimbursing expenses	0.98%	[1]

Example

This example is intended to help you compare the cost of investing in the Global Opportunities Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Global Opportunities Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	One Year	Three Years	Five Years	Ten Years
Aristotle/Saul Global Opportunities Fund | Class I Shares | USD ($)	100	342	633	1,462

Portfolio Turnover

The Global Opportunities Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Global Opportunities Fund's portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Global Opportunities Fund primarily invests its assets in equity securities that are listed on an exchange or that are otherwise publicly traded in the United States or in a foreign country. However, the Global Opportunities Fund may also invest in a variety of other instruments traded in U.S. and foreign markets, including, but not limited to, fixed income securities, convertible securities, and unlisted equity securities. The Global Opportunities Fund may also invest in exchange-traded funds ("ETFs"). ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

Under normal market conditions, the Global Opportunities Fund invests in at least three different countries, including emerging market countries, with at least 40% of its net assets invested in securities of issuers located outside the United States. The Global Opportunities Fund's investments in foreign securities may include investments through American, European and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). Depository receipts represent interests in foreign securities held on deposit by banks.

The Global Opportunities Fund does not limit the types of companies in which it seeks to invest its assets based on market capitalization.

The Global Opportunities Fund's investments in fixed income securities may be of any maturity and credit quality, including securities rated below investment grade (commonly referred to as "junk" bonds). The Global Opportunities Fund generally holds its investments for the long term.

In selecting investments for the Global Opportunities Fund, the Fund's investment advisor (Aristotle Capital Management, LLC) employs a fundamental, bottom-up approach. The Advisor focuses first on the quality of a company's business and then considers whether the company's securities are available at an attractive price.

In addition, the Global Opportunities Fund may pursue tactical investment strategies from time to time in order to seek favorable returns on securities that the Advisor believes are over-valued based on its assessment of their prices. These tactical strategies may include, for example, short sales, investments in warrants, futures, forward contracts, distressed debt, preferred securities, and convertible securities, and purchase and sale of options, based on the Advisor's assessment of the fair value of the instrument or, as applicable, the underlying or related instrument (e.g., the stock on which an option is purchased). The Global Opportunities Fund may also pursue merger arbitrage opportunities in an effort to profit from any discount in the price of a target company's stock prior to the closing of a merger.

The Global Opportunities Fund generally seeks favorable performance relative to its benchmark, the MSCI All Country World Index (net). However, the Advisor is not constrained by the composition of the MSCI All Country World Index in selecting investments for the Global Opportunities Fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Global Opportunities Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objective.

Asset Segregation Risk. As a series of an investment company registered with the SEC, the Fund must segregate liquid assets, or engage in other measures to "cover" open positions with respect to certain kinds of derivatives and short sales. The Global Opportunities Fund may incur losses on derivatives and other leveraged investments (including the entire amount of the Fund's investment in such investments) even if they are covered.

Convertible Securities Risk. Convertible securities are subject to market and interest rate risk and credit risk. When the market price of the equity security underlying a convertible security decreases the convertible security tends to trade on the basis of its yield and other fixed income characteristics, and is more susceptible to credit and interest rate risks. When the market price of such equity security rises, the convertible security tends to trade on the basis of its equity conversion features and be more exposed to market risk. Convertible securities are typically issued by smaller capitalized companies with stock prices that may be more volatile than those of other companies.

Credit Risk. If an issuer or guarantor of a debt security held by the Global Opportunities Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Global Opportunities Fund's portfolio will typically decline. Junk bonds have a higher risk of default than other fixed income securities and are considered predominantly speculative.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. Dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. Major types of derivatives include futures, options, swaps and forward contracts. Using derivatives can have a leveraging effect and increase fund volatility. Derivatives transactions can be highly illiquid and difficult to unwind or value, and changes in the value of a derivative held by the Fund may not correlate with the value of the underlying instrument or the Fund's other investments. Many of the risks applicable to trading the instruments underlying derivatives are also applicable to derivatives trading. However, additional risks are associated with derivatives trading that are possibly greater than the risks associated with investing directly in the underlying instruments. These additional risks include, but are not limited to, illiquidity risk and counterparty credit risk. For derivatives that are required to be cleared by a regulated clearinghouse, other risks may arise from the Fund's relationship with a brokerage firm through which it submits derivatives trades for clearing, including in some cases from other clearing customers of the brokerage firm.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Equity Risk. The value of the equity securities held by the Global Opportunities Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Global Opportunities Fund participate, or factors relating to specific companies in which the Fund invests.

ETF Risk. Investing in an ETF will provide the Global Opportunities Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Global Opportunities Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Global Opportunities Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and GDR. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

High Yield ("Junk") Bond Risk. High yield bonds are debt securities rated below investment grade (often called "junk bonds"). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Leveraging Risk. Certain Fund transactions, including entering into futures contracts and taking short positions in financial instruments, may give rise to a form of leverage. Leverage can magnify the effects of changes in the value of the Global Opportunities Fund's investments and make the Fund more volatile. Leverage creates a risk of loss of value on a larger pool of assets than the Global Opportunities Fund would otherwise have had, potentially resulting in the loss of all assets. The Global Opportunities Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Liquidity Risk. The Global Opportunities Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Global Opportunities Fund's investments. Illiquid assets may also be difficult to value.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Global Opportunities Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases between the date of the short sale and the date on which the Global Opportunities Fund replaces the security or other instrument borrowed to make the short sale, the Global Opportunities Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

[1] The Global Opportunities Fund's Advisor has contractually agreed to waive its fees and/or pay for operating expenses of the Fund to ensure that total annual fund operating expenses (excluding any taxes, leverage interest, brokerage commissions, dividend and interest expenses on short sales, acquired fund fees and expenses (as determined in accordance with Form N-1A) expenses incurred in connection with any merger or reorganization, and extraordinary expenses such as litigation expenses) do not exceed 0.98% of the average daily net assets of Class I Shares of the Global Opportunities Fund. This agreement is in effect until April 30, 2020, and it may be terminated before that date only by the Trust's Board of Trustees. The Global Opportunities Fund's Advisor is permitted to seek reimbursement from the Fund, subject to certain limitations, of fees waived or payments made to the Fund for a period ending three full fiscal years after the date of the waiver or payment. This reimbursement may be requested from the Fund if the reimbursement will not cause the Fund's annual expense ratio to exceed the lesser of (a) the expense limitation in effect at the time such fees were waived or payments made, or (b) the expense limitation in effect at the time of the reimbursement.

Expense Example	One Year	Three Years	Five Years	Ten Years
Aristotle International Equity Fund | Class I Shares | USD ($)	95	455	998	2,485

Portfolio Turnover

The International Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the International Equity Fund's portfolio turnover rate was 10% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the International Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in publicly traded equity securities or depository receipts of companies organized, headquartered or doing a substantial amount of business outside of the United States. Aristotle Capital Management, LLC, the International Equity Fund's Advisor, considers a company that has at least 50% of its assets located outside the United States or derives at least 50% of its revenue from business outside the United States as doing a substantial amount of business outside the United States. The International Equity Fund generally invests in securities of companies located in different regions and in at least three different countries. The International Equity Fund intends to invest no more than 20% of its total assets in companies organized, headquartered or doing a substantial amount of business in emerging market countries under normal market conditions.

The International Equity Fund's investments in equity securities may include common stocks, preferred stocks, warrants and rights. The International Equity Fund's investments in depository receipts may include American, European, and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets. The International Equity Fund may invest in companies of any market capitalization.

In pursuing the International Equity Fund's investment objective, the Advisor employs a fundamental, bottom-up research driven approach to identify companies for investment by the Fund. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value. The Advisor seeks to identify high quality companies by focusing on the following attributes: attractive business fundamentals, strong financials, experienced, motivated company management, and high and/or consistently improving market position, return on invested capital or operating margins.

The International Equity Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose your money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the International Equity Fund, which may cause investors to lose money. There can be no assurance that the International Equity Fund will achieve its investment objective.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. Dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Equity Risk. The value of the equity securities held by the International Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the International Equity Fund participate, or factors relating to specific companies in which the Fund invests.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the International Equity Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and GDRs. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Non-Diversification Risk. The International Equity Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

Example

This example is intended to help you compare the cost of investing in the Strategic Credit Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Strategic Credit Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Strategic Credit Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	One Year	Three Years	Five Years	Ten Years
Aristotle Strategic Credit Fund | Class I Shares | USD ($)	63	694	1,351	3,113

Portfolio Turnover

The Strategic Credit Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Strategic Credit Fund's portfolio turnover rate was 69% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Strategic Credit Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities. The types of debt securities in which the Fund may invest include, but are not limited to, corporate bonds, notes and debentures of U.S. and non-U.S. issuers, and bank loans of U.S. and non-U.S. corporate issuers. The Strategic Credit Fund's investments in foreign securities include securities in both developed and emerging markets.

The Strategic Credit Fund may invest in debt securities of any maturity and credit quality. Under normal market conditions, the Fund's Advisor, Aristotle Credit Partners, LLC, expects that the Fund will generally invest in investment grade corporate bonds as well as high yield bonds and in bank loans that are generally both rated in the "B" and "BB" quality tiers of the high yield categories by nationally recognized securities rating organizations at the time of purchase or, if unrated, determined by the Advisor to be of comparable credit quality. However, the Strategic Credit Fund may also invest in corporate debt investments rated below "B". The Advisor believes these securities with these credit ratings provide the optimal risk-adjusted performance over a market cycle. Investment grade securities are those rated in the Baa3 or higher categories by Moody's Investors Service, Inc. ("Moody's"), or in the BBB- or higher categories by Standard & Poor's, a division of McGraw Hill Companies Inc. ("S&P"), or Fitch Ratings Ltd. ("Fitch") or, if unrated by S&P, Moody's or Fitch, determined by the Advisor to be of comparable credit quality. High yield bonds, commonly referred to as "junk bonds" and bank loans, are generally rated below investment grade by Moody's, S&P, or Fitch.

In pursuing the Strategic Credit Fund's investment objectives, the Advisor uses a disciplined investment approach that integrates a top-down macroeconomic environment assessment with a bottom-up fundamental credit analysis. The Advisor seeks to identify and invest in securities of companies with stable or improving financial profiles.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Strategic Credit Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Strategic Credit Fund will achieve its investment objective.

Bank Loan Risk. The Strategic Credit Fund's investments in assignments of bank loans may create substantial risk. Although the Strategic Credit Fund expects it will invest in senior and secured bank loans, the Fund may invest in unsecured or subordinated loans. In addition, the Fund may invest in secured and unsecured participations in bank loans. These bank loans will generally be rated below investment grade. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Strategic Credit Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of the underlying borrower. If the Strategic Credit Fund invests in a bank loan through a participation, the Fund will also be exposed to the credit risk of financial institution selling the participation to the Fund as well as the credit risk of the underlying borrower. The market for bank loan may not be highly liquid and the Fund may have difficulty selling them. Bank loans have similar risks to high yield bonds and are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing bank loans are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings. Unlike senior secured loans which have a priority claim on the borrower's assets and are secured with the borrower's assets and/or equity, unsecured or subordinated loans may carry greater risk since they will not have a priority claim and may not be secured by the borrower's assets.

Credit Risk. If an issuer or guarantor of a debt security held by the Strategic Credit Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund's portfolio will typically decline. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Extension Risk. If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market which may cause the value of the securities to fall.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include American Depository Receipts ("ADRs") and Global Depository Receipts ("GDRs"). Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

High Yield ("Junk") Bond Risk. High yield bonds are debt securities rated below investment grade (often called "junk bonds"). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Interest Rate Risk. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, with longer-term securities being more sensitive than shorter-term securities. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Generally, the longer the maturity and duration of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund's income. Changes in governmental policy, rising inflation rates, and general economic developments, among other factors, could cause interest rates to increase and could have a substantial and immediate effect on the values of the Fund's investments. In addition, a potential rise in interest rates may result in periods of volatility and increased redemptions that might require the Fund to liquidate portfolio securities at disadvantageous prices and times.

Liquidity Risk. The Strategic Credit Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Fund's investments. Illiquid assets may also be difficult to value.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Prepayment or Call Risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Strategic Credit Fund may not benefit from the rise in market price that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Strategic Credit Fund may also lose any premium it paid on the security.

Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds and thus will be more susceptible to negative events affecting those sectors. For example, as of December 31, 2017, 25.6% of the Strategic Credit Fund's assets were invested in the consumer discretionary sector. Companies in the consumer discretionary sector may be adversely impacted by fluctuations in supply and demand, changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending.

Valuation Risk. The sales price the Strategic Credit Fund could receive for any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued by the Fund using a fair value methodology. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the Fund had not fair-valued the security or had used a different valuation methodology.

Example

This example is intended to help you compare the cost of investing in the Value Equity Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Value Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Value Equity Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	One Year	Three Years	Five Years	Ten Years
Aristotle Value Equity Fund | Class I Shares | USD ($)	80	656	1,649	4,174

Portfolio Turnover

The Value Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Value Equity Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Value Equity Fund's portfolio turnover rate was 14% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Value Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities. The Value Equity Fund's investments in equity securities may include common stocks, depository receipts, and exchange-traded funds ("ETFs") that invest primarily in equity securities. Depository receipts represent interests in foreign securities held on deposit by banks. ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

The Value Equity Fund seeks to meet its investment objective by investing primarily in equity securities of domestic and foreign issuers that are listed on a U.S. exchange or that are otherwise publicly traded in the United States but may invest up to 20% of its total assets in American Depository Receipts and Global Depository Receipts ("ADRs" and "GDRs", respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets.

In selecting investments for the Value Equity Fund, the Advisor employs a fundamental, bottom-up approach. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value and have a minimum market capitalization of $2 billion. The Advisor seeks to identify high quality businesses by focusing on companies with the following attributes: attractive business fundamentals; experienced, motivated company management; pricing power; sustainable competitive advantages; financial strength; and/or high or consistently improving market position, return on invested capital and operating margins.

The Value Equity Fund generally seeks favorable performance relative to its benchmark, the Russell 1000 Value Index. However, the Advisor is not constrained by the composition of the Russell 1000 Value Index in selecting investments for the Fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Value Equity Fund is set forth below. Before you decide whether to invest in the Value Equity Fund, carefully consider these risk factors associated with investing in the Value Equity Fund, which may cause investors to lose money. There can be no assurance that the Value Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Value Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Value Equity Fund participate, or factors relating to specific companies in which the Fund invests.

ETF Risk. Investing in an ETF will provide the Value Equity Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Value Equity Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and Global Depository Receipts ("GDRs") Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends. Emerging markets tend to be more volatile than the markets of more mature economies and generally have less diverse and less mature economic structures and less stable political systems than those of developed countries.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors. For example, as of December 31, 2017, 24.5% of the Value Equity Fund's assets were invested in the financial sector. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others: government regulations of, or related to, the sector; governmental monetary and fiscal policies; economic, business or political conditions; credit rating downgrades; changes in interest rates; price competition; and decreased liquidity in credit markets. This sector has experienced significant losses and a high degree of volatility in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

Expense Example	One Year	Three Years	Five Years	Ten Years
Aristotle Small Cap Equity Fund | Class I Shares | USD ($)	99	309	536	1,190

Portfolio Turnover

The Small Cap Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Small Cap Equity Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Small Cap Equity Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 42% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Small Cap Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities of small capitalization companies. Aristotle Capital Boston, LLC, the Small Cap Equity Fund's Advisor, considers small capitalization companies to be those companies that, at the time of initial purchase, have a market capitalization equal to or less than that of the largest company in the Russell 2000® Index during the most recent 12-month period (approximately $14.3 billion during the 12-month period ended December 31, 2017). The Russell 2000® Index is reconstituted annually. Because small capitalization companies are defined by reference to an index, the range of market capitalization of companies in which the Small Cap Equity Fund invests may vary with market conditions. Investments in companies that move above or below the capitalization range may continue to be held by the Small Cap Equity Fund in the Advisor's sole discretion. The Small Cap Equity Fund's investments in equity securities may include common stocks, depository receipts, and exchange traded-funds ("ETFs") that invest primarily in equity securities of small capitalization companies. Depository receipts represent interests in foreign securities held on deposit by banks. ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

The Small Cap Equity Fund seeks to meet its investment objective by investing primarily in equity securities of U.S. issuers but may invest up to 5% of its total assets in American Depository Receipts ("ADRs"). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks.

In pursuing the Small Cap Equity Fund's investment objective, the Advisor employs a fundamental, bottom-up research driven approach to identify companies for investment by the Small Cap Equity Fund. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value. The Advisor seeks to identify high quality businesses by focusing on companies with the following attributes: disciplined business plans; attractive business fundamentals; sound balance sheets; financial strength; experienced, motivated company management; reasonable competition; and/or a record of long-term value creation.

The Fund generally seeks favorable performance relative to its benchmark, the Russell 2000 Index. However, the Advisor is not constrained by the composition of the Russell 2000 Index in selecting investments for the Fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Small Cap Equity Fund is set forth below. Before you decide whether to invest in the Small Cap Equity Fund, carefully consider these risk factors associated with investing in the Small Cap Equity Fund, which may cause investors to lose money. There can be no assurance that the Small Cap Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Small Cap Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Small Cap Equity Fund invests.

ETF Risk. Investing in an ETF will provide the Small Cap Equity Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Small Cap Equity Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs. Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Small-Cap Company Risk. The securities of small-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

Aristotle Core Equity Fund

SUMMARY SECTION – Aristotle Core Equity Fund

Investment Objective

The investment objective of the Aristotle Core Equity Fund (the "Core Equity Fund") is to seek long-term growth of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Core Equity Fund.

Shareholder Fees
(fees paid directly from your investment)

Shareholder Fees	Aristotle Core Equity Fund Class I Shares USD ($)
Maximum sales charge (load) imposed on purchases	none
Maximum deferred sales charge (load)	none
Redemption fee if redeemed within 30 days of purchase (as a percentage of amount redeemed)	1.00%
Wire fee	$ 20
Overnight check delivery fee	25
Retirement account fees (annual maintenance fee)	$ 15

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Aristotle Core Equity Fund Class I Shares
Management fees	0.50%
Distribution (Rule 12b-1) fees	none
Shareholder servicing fees	0.10%
All other expenses	5.25%
Other expenses	5.35%
Total annual fund operating expenses	5.85%
Fees waived and/or expenses reimbursed	(5.20%)	[1]
Total annual fund operating expenses after waiving fees and/or reimbursing expenses	0.65%	[1]

Example

This example is intended to help you compare the cost of investing in the Core Equity Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Core Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Core Equity Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	One Year	Three Years	Five Years	Ten Years
Aristotle Core Equity Fund | Class I Shares | USD ($)	66	1,277	2,467	5,355

Portfolio Turnover

The Core Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Core Equity Fund's performance. During the period March 31, 2017 (commencement date) through December 31, 2017, the Fund's portfolio turnover rate was 22% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Core Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities. The Core Equity Fund's investments in equity securities may include common stocks, preferred stocks, convertible preferred stocks, depository receipts, shares of publicly-traded real estate investment trusts ("REITs"), warrants and rights. The Core Equity Fund's investments in depository receipts may include American, European, and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets. Although the Core Equity Fund may invest in companies of any market capitalization and from any country, it invests primarily in large U.S. companies.

In pursuing the Core Equity Fund's investment objective, Aristotle Atlantic Partners, LLC, the Core Equity Fund's Advisor, employs a fundamental, bottom-up research driven approach to identify companies for investment by the Core Equity Fund. The Advisor seeks to identify companies that it believes are positioned to benefit from one or more of the following: (i) shifts in industry spending, government spending and consumer trends; (ii) gains in market share from innovative products and strong intellectual property; and (iii) cyclical trends in the industry in which they operate and capable management that can take advantage of those trends. At times, the Core Equity Fund's assets may be invested in securities of relatively few industries or sectors.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Core Equity Fund is set forth below. Before you decide whether to invest in the Core Equity Fund, carefully consider these risk factors associated with investing in the Core Equity Fund, which may cause investors to lose money. There can be no assurance that the Core Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Core Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Core Equity Fund participate, or factors relating to specific companies in which the Core Equity Fund invests.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Core Equity Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs, EDRs and GDRs. Unsponsored ADRs, EDRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, and the issuing bank may deduct custody, foreign currency exchange, and other fees from the payment of dividends.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Preferred Stock Risk. Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. The market value of preferred stock is subject to company-specific and market risks applicable generally to equity securities and is also sensitive to changes in the company's creditworthiness, the ability of the company to make payments on the preferred stock, and changes in interest rates, typically declining in value if interest rates rise. Convertible preferred stock allows the holder to convert the preferred shares into a fixed number of common shares, usually after a predetermined date. Like preferred stock, convertible preferred stock generally pays a dividend at a specified rate and has preference over common stock in the payment of dividends but ranks behind bonds, including convertible bonds, in priority upon liquidation.

Real Estate Investment Trust (REIT) Risk. The Core Equity Fund's investment in REITs will subject the Core Equity Fund to risks similar to those associated with direct ownership of real estate, including losses from casualty or condemnation, and changes in local and general economic, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses.

Sector Focus Risk. The Core Equity Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Warrants and Rights Risk. Warrants and rights may lack a liquid secondary market for resale. The prices of warrants and rights may fluctuate as a result of speculation or other factors. Warrants and rights can provide a greater potential for profit or loss than an equivalent investment in the underlying security. Prices of warrants and rights do not necessarily move in tandem with the prices of their underlying securities and therefore are highly volatile and speculative investments. If a warrant or right expires without being exercised, the Fund will lose any amount paid for the warrant or right.

Performance

The Fund is new and does not have a full calendar year performance record to compare against other mutual funds or broad measures of securities market performance such as indices. Performance information will be available after the Fund has been in operation for one calendar year.

[1] The Core Equity Fund's advisor has contractually agreed to waive its fees and/or pay for operating expenses of the Core Equity Fund to ensure that total annual fund operating expenses (excluding any taxes, leverage interest, brokerage commissions, dividend and interest expenses on short sales, acquired fund fees and expenses (as determined in accordance with Form N-1A), expenses incurred in connection with any merger or reorganization, and extraordinary expenses such as litigation expenses) do not exceed 0.65% of the Core Equity Fund's average daily net assets. This agreement is in effect until April 30, 2019, and it may be terminated before that date only by the Trust's Board of Trustees. The Core Equity Fund's Advisor is permitted to seek reimbursement from the Fund, subject to certain limitations, of fees waived or payments made to the Core Equity Fund for a period ending three full fiscal years after the date of the waiver or payment. This reimbursement may be requested from the Fund if the reimbursement will not cause the Fund's annual expense ratio to exceed the lesser of (a) the expense limitation in effect at the time such fees were waived or payments made, or (b) the expense limitation in effect at the time of the reimbursement.

Aristotle/Saul Global Opportunities Fund

SUMMARY SECTION – Aristotle/Saul Global Opportunities Fund

Investment Objective

The investment objective of the Aristotle/Saul Global Opportunities Fund (the "Global Opportunities Fund") is to seek to maximize long-term capital appreciation and income.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Global Opportunities Fund.

Shareholder Fees
(fees paid directly from your investment)

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Global Opportunities Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Global Opportunities Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Global Opportunities Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Global Opportunities Fund's portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Global Opportunities Fund primarily invests its assets in equity securities that are listed on an exchange or that are otherwise publicly traded in the United States or in a foreign country. However, the Global Opportunities Fund may also invest in a variety of other instruments traded in U.S. and foreign markets, including, but not limited to, fixed income securities, convertible securities, and unlisted equity securities. The Global Opportunities Fund may also invest in exchange-traded funds ("ETFs"). ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

Under normal market conditions, the Global Opportunities Fund invests in at least three different countries, including emerging market countries, with at least 40% of its net assets invested in securities of issuers located outside the United States. The Global Opportunities Fund's investments in foreign securities may include investments through American, European and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). Depository receipts represent interests in foreign securities held on deposit by banks.

The Global Opportunities Fund does not limit the types of companies in which it seeks to invest its assets based on market capitalization.

The Global Opportunities Fund's investments in fixed income securities may be of any maturity and credit quality, including securities rated below investment grade (commonly referred to as "junk" bonds). The Global Opportunities Fund generally holds its investments for the long term.

In selecting investments for the Global Opportunities Fund, the Fund's investment advisor (Aristotle Capital Management, LLC) employs a fundamental, bottom-up approach. The Advisor focuses first on the quality of a company's business and then considers whether the company's securities are available at an attractive price.

In addition, the Global Opportunities Fund may pursue tactical investment strategies from time to time in order to seek favorable returns on securities that the Advisor believes are over-valued based on its assessment of their prices. These tactical strategies may include, for example, short sales, investments in warrants, futures, forward contracts, distressed debt, preferred securities, and convertible securities, and purchase and sale of options, based on the Advisor's assessment of the fair value of the instrument or, as applicable, the underlying or related instrument (e.g., the stock on which an option is purchased). The Global Opportunities Fund may also pursue merger arbitrage opportunities in an effort to profit from any discount in the price of a target company's stock prior to the closing of a merger.

The Global Opportunities Fund generally seeks favorable performance relative to its benchmark, the MSCI All Country World Index (net). However, the Advisor is not constrained by the composition of the MSCI All Country World Index in selecting investments for the Global Opportunities Fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Global Opportunities Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objective.

Asset Segregation Risk. As a series of an investment company registered with the SEC, the Fund must segregate liquid assets, or engage in other measures to "cover" open positions with respect to certain kinds of derivatives and short sales. The Global Opportunities Fund may incur losses on derivatives and other leveraged investments (including the entire amount of the Fund's investment in such investments) even if they are covered.

Convertible Securities Risk. Convertible securities are subject to market and interest rate risk and credit risk. When the market price of the equity security underlying a convertible security decreases the convertible security tends to trade on the basis of its yield and other fixed income characteristics, and is more susceptible to credit and interest rate risks. When the market price of such equity security rises, the convertible security tends to trade on the basis of its equity conversion features and be more exposed to market risk. Convertible securities are typically issued by smaller capitalized companies with stock prices that may be more volatile than those of other companies.

Credit Risk. If an issuer or guarantor of a debt security held by the Global Opportunities Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Global Opportunities Fund's portfolio will typically decline. Junk bonds have a higher risk of default than other fixed income securities and are considered predominantly speculative.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. Dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. Major types of derivatives include futures, options, swaps and forward contracts. Using derivatives can have a leveraging effect and increase fund volatility. Derivatives transactions can be highly illiquid and difficult to unwind or value, and changes in the value of a derivative held by the Fund may not correlate with the value of the underlying instrument or the Fund's other investments. Many of the risks applicable to trading the instruments underlying derivatives are also applicable to derivatives trading. However, additional risks are associated with derivatives trading that are possibly greater than the risks associated with investing directly in the underlying instruments. These additional risks include, but are not limited to, illiquidity risk and counterparty credit risk. For derivatives that are required to be cleared by a regulated clearinghouse, other risks may arise from the Fund's relationship with a brokerage firm through which it submits derivatives trades for clearing, including in some cases from other clearing customers of the brokerage firm.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Equity Risk. The value of the equity securities held by the Global Opportunities Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Global Opportunities Fund participate, or factors relating to specific companies in which the Fund invests.

ETF Risk. Investing in an ETF will provide the Global Opportunities Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Global Opportunities Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Global Opportunities Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and GDR. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

High Yield ("Junk") Bond Risk. High yield bonds are debt securities rated below investment grade (often called "junk bonds"). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Leveraging Risk. Certain Fund transactions, including entering into futures contracts and taking short positions in financial instruments, may give rise to a form of leverage. Leverage can magnify the effects of changes in the value of the Global Opportunities Fund's investments and make the Fund more volatile. Leverage creates a risk of loss of value on a larger pool of assets than the Global Opportunities Fund would otherwise have had, potentially resulting in the loss of all assets. The Global Opportunities Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Liquidity Risk. The Global Opportunities Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Global Opportunities Fund's investments. Illiquid assets may also be difficult to value.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Global Opportunities Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases between the date of the short sale and the date on which the Global Opportunities Fund replaces the security or other instrument borrowed to make the short sale, the Global Opportunities Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

The example assumes that you invest $10,000 in the International Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the International Equity Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The International Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the International Equity Fund's portfolio turnover rate was 10% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the International Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in publicly traded equity securities or depository receipts of companies organized, headquartered or doing a substantial amount of business outside of the United States. Aristotle Capital Management, LLC, the International Equity Fund's Advisor, considers a company that has at least 50% of its assets located outside the United States or derives at least 50% of its revenue from business outside the United States as doing a substantial amount of business outside the United States. The International Equity Fund generally invests in securities of companies located in different regions and in at least three different countries. The International Equity Fund intends to invest no more than 20% of its total assets in companies organized, headquartered or doing a substantial amount of business in emerging market countries under normal market conditions.

The International Equity Fund's investments in equity securities may include common stocks, preferred stocks, warrants and rights. The International Equity Fund's investments in depository receipts may include American, European, and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets. The International Equity Fund may invest in companies of any market capitalization.

In pursuing the International Equity Fund's investment objective, the Advisor employs a fundamental, bottom-up research driven approach to identify companies for investment by the Fund. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value. The Advisor seeks to identify high quality companies by focusing on the following attributes: attractive business fundamentals, strong financials, experienced, motivated company management, and high and/or consistently improving market position, return on invested capital or operating margins.

The International Equity Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose your money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the International Equity Fund, which may cause investors to lose money. There can be no assurance that the International Equity Fund will achieve its investment objective.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. Dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Equity Risk. The value of the equity securities held by the International Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the International Equity Fund participate, or factors relating to specific companies in which the Fund invests.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the International Equity Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and GDRs. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Non-Diversification Risk. The International Equity Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

SUMMARY SECTION – Aristotle Strategic Credit Fund

Investment Objectives

The investment objectives of the Aristotle Strategic Credit Fund (the "Strategic Credit Fund") are to seek income and capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Strategic Credit Fund.

Shareholder Fees

(fees paid directly from your investment)

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)    

Example

This example is intended to help you compare the cost of investing in the Strategic Credit Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Strategic Credit Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Strategic Credit Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Strategic Credit Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Strategic Credit Fund's portfolio turnover rate was 69% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Strategic Credit Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities. The types of debt securities in which the Fund may invest include, but are not limited to, corporate bonds, notes and debentures of U.S. and non-U.S. issuers, and bank loans of U.S. and non-U.S. corporate issuers. The Strategic Credit Fund's investments in foreign securities include securities in both developed and emerging markets.

The Strategic Credit Fund may invest in debt securities of any maturity and credit quality. Under normal market conditions, the Fund's Advisor, Aristotle Credit Partners, LLC, expects that the Fund will generally invest in investment grade corporate bonds as well as high yield bonds and in bank loans that are generally both rated in the "B" and "BB" quality tiers of the high yield categories by nationally recognized securities rating organizations at the time of purchase or, if unrated, determined by the Advisor to be of comparable credit quality. However, the Strategic Credit Fund may also invest in corporate debt investments rated below "B". The Advisor believes these securities with these credit ratings provide the optimal risk-adjusted performance over a market cycle. Investment grade securities are those rated in the Baa3 or higher categories by Moody's Investors Service, Inc. ("Moody's"), or in the BBB- or higher categories by Standard & Poor's, a division of McGraw Hill Companies Inc. ("S&P"), or Fitch Ratings Ltd. ("Fitch") or, if unrated by S&P, Moody's or Fitch, determined by the Advisor to be of comparable credit quality. High yield bonds, commonly referred to as "junk bonds" and bank loans, are generally rated below investment grade by Moody's, S&P, or Fitch.

In pursuing the Strategic Credit Fund's investment objectives, the Advisor uses a disciplined investment approach that integrates a top-down macroeconomic environment assessment with a bottom-up fundamental credit analysis. The Advisor seeks to identify and invest in securities of companies with stable or improving financial profiles.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Strategic Credit Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Strategic Credit Fund will achieve its investment objective.

Bank Loan Risk. The Strategic Credit Fund's investments in assignments of bank loans may create substantial risk. Although the Strategic Credit Fund expects it will invest in senior and secured bank loans, the Fund may invest in unsecured or subordinated loans. In addition, the Fund may invest in secured and unsecured participations in bank loans. These bank loans will generally be rated below investment grade. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Strategic Credit Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of the underlying borrower. If the Strategic Credit Fund invests in a bank loan through a participation, the Fund will also be exposed to the credit risk of financial institution selling the participation to the Fund as well as the credit risk of the underlying borrower. The market for bank loan may not be highly liquid and the Fund may have difficulty selling them. Bank loans have similar risks to high yield bonds and are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing bank loans are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings. Unlike senior secured loans which have a priority claim on the borrower's assets and are secured with the borrower's assets and/or equity, unsecured or subordinated loans may carry greater risk since they will not have a priority claim and may not be secured by the borrower's assets.

Credit Risk. If an issuer or guarantor of a debt security held by the Strategic Credit Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund's portfolio will typically decline. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Extension Risk. If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market which may cause the value of the securities to fall.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include American Depository Receipts ("ADRs") and Global Depository Receipts ("GDRs"). Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

High Yield ("Junk") Bond Risk. High yield bonds are debt securities rated below investment grade (often called "junk bonds"). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Interest Rate Risk. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, with longer-term securities being more sensitive than shorter-term securities. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Generally, the longer the maturity and duration of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund's income. Changes in governmental policy, rising inflation rates, and general economic developments, among other factors, could cause interest rates to increase and could have a substantial and immediate effect on the values of the Fund's investments. In addition, a potential rise in interest rates may result in periods of volatility and increased redemptions that might require the Fund to liquidate portfolio securities at disadvantageous prices and times.

Liquidity Risk. The Strategic Credit Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Fund's investments. Illiquid assets may also be difficult to value.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Prepayment or Call Risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Strategic Credit Fund may not benefit from the rise in market price that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Strategic Credit Fund may also lose any premium it paid on the security.

Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds and thus will be more susceptible to negative events affecting those sectors. For example, as of December 31, 2017, 25.6% of the Strategic Credit Fund's assets were invested in the consumer discretionary sector. Companies in the consumer discretionary sector may be adversely impacted by fluctuations in supply and demand, changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending.

Valuation Risk. The sales price the Strategic Credit Fund could receive for any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued by the Fund using a fair value methodology. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the Fund had not fair-valued the security or had used a different valuation methodology.

Investment Objective

The investment objective of the Aristotle Value Equity Fund (the "Value Equity Fund") is to maximize long-term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Value Equity Fund.

Shareholder Fees

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Value Equity Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Value Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Value Equity Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Value Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Value Equity Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Value Equity Fund's portfolio turnover rate was 14% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Value Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities. The Value Equity Fund's investments in equity securities may include common stocks, depository receipts, and exchange-traded funds ("ETFs") that invest primarily in equity securities. Depository receipts represent interests in foreign securities held on deposit by banks. ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

The Value Equity Fund seeks to meet its investment objective by investing primarily in equity securities of domestic and foreign issuers that are listed on a U.S. exchange or that are otherwise publicly traded in the United States but may invest up to 20% of its total assets in American Depository Receipts and Global Depository Receipts ("ADRs" and "GDRs", respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets.

In selecting investments for the Value Equity Fund, the Advisor employs a fundamental, bottom-up approach. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value and have a minimum market capitalization of $2 billion. The Advisor seeks to identify high quality businesses by focusing on companies with the following attributes: attractive business fundamentals; experienced, motivated company management; pricing power; sustainable competitive advantages; financial strength; and/or high or consistently improving market position, return on invested capital and operating margins.

The Value Equity Fund generally seeks favorable performance relative to its benchmark, the Russell 1000 Value Index. However, the Advisor is not constrained by the composition of the Russell 1000 Value Index in selecting investments for the Fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Value Equity Fund is set forth below. Before you decide whether to invest in the Value Equity Fund, carefully consider these risk factors associated with investing in the Value Equity Fund, which may cause investors to lose money. There can be no assurance that the Value Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Value Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Value Equity Fund participate, or factors relating to specific companies in which the Fund invests.

ETF Risk. Investing in an ETF will provide the Value Equity Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Value Equity Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and Global Depository Receipts ("GDRs") Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends. Emerging markets tend to be more volatile than the markets of more mature economies and generally have less diverse and less mature economic structures and less stable political systems than those of developed countries.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors. For example, as of December 31, 2017, 24.5% of the Value Equity Fund's assets were invested in the financial sector. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others: government regulations of, or related to, the sector; governmental monetary and fiscal policies; economic, business or political conditions; credit rating downgrades; changes in interest rates; price competition; and decreased liquidity in credit markets. This sector has experienced significant losses and a high degree of volatility in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

SUMMARY SECTION – Aristotle Small Cap Equity Fund

Investment Objective

The investment objective of the Aristotle Small Cap Equity Fund (the "Small Cap Equity Fund") is to seek long-term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Small Cap Equity Fund.

Shareholder Fees
(fees paid directly from your investment)

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Small Cap Equity Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Small Cap Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Small Cap Equity Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Small Cap Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Small Cap Equity Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Small Cap Equity Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 42% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Small Cap Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities of small capitalization companies. Aristotle Capital Boston, LLC, the Small Cap Equity Fund's Advisor, considers small capitalization companies to be those companies that, at the time of initial purchase, have a market capitalization equal to or less than that of the largest company in the Russell 2000® Index during the most recent 12-month period (approximately $14.3 billion during the 12-month period ended December 31, 2017). The Russell 2000® Index is reconstituted annually. Because small capitalization companies are defined by reference to an index, the range of market capitalization of companies in which the Small Cap Equity Fund invests may vary with market conditions. Investments in companies that move above or below the capitalization range may continue to be held by the Small Cap Equity Fund in the Advisor's sole discretion. The Small Cap Equity Fund's investments in equity securities may include common stocks, depository receipts, and exchange traded-funds ("ETFs") that invest primarily in equity securities of small capitalization companies. Depository receipts represent interests in foreign securities held on deposit by banks. ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

The Small Cap Equity Fund seeks to meet its investment objective by investing primarily in equity securities of U.S. issuers but may invest up to 5% of its total assets in American Depository Receipts ("ADRs"). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks.

In pursuing the Small Cap Equity Fund's investment objective, the Advisor employs a fundamental, bottom-up research driven approach to identify companies for investment by the Small Cap Equity Fund. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value. The Advisor seeks to identify high quality businesses by focusing on companies with the following attributes: disciplined business plans; attractive business fundamentals; sound balance sheets; financial strength; experienced, motivated company management; reasonable competition; and/or a record of long-term value creation.

The Fund generally seeks favorable performance relative to its benchmark, the Russell 2000 Index. However, the Advisor is not constrained by the composition of the Russell 2000 Index in selecting investments for the Fund.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Small Cap Equity Fund is set forth below. Before you decide whether to invest in the Small Cap Equity Fund, carefully consider these risk factors associated with investing in the Small Cap Equity Fund, which may cause investors to lose money. There can be no assurance that the Small Cap Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Small Cap Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Small Cap Equity Fund invests.

ETF Risk. Investing in an ETF will provide the Small Cap Equity Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Small Cap Equity Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs. Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Small-Cap Company Risk. The securities of small-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

Aristotle Core Equity Fund

SUMMARY SECTION – Aristotle Core Equity Fund

Investment Objective

The investment objective of the Aristotle Core Equity Fund (the "Core Equity Fund") is to seek long-term growth of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Core Equity Fund.

Shareholder Fees
(fees paid directly from your investment)

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Core Equity Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Core Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Core Equity Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Core Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Core Equity Fund's performance. During the period March 31, 2017 (commencement date) through December 31, 2017, the Fund's portfolio turnover rate was 22% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Core Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities. The Core Equity Fund's investments in equity securities may include common stocks, preferred stocks, convertible preferred stocks, depository receipts, shares of publicly-traded real estate investment trusts ("REITs"), warrants and rights. The Core Equity Fund's investments in depository receipts may include American, European, and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets. Although the Core Equity Fund may invest in companies of any market capitalization and from any country, it invests primarily in large U.S. companies.

In pursuing the Core Equity Fund's investment objective, Aristotle Atlantic Partners, LLC, the Core Equity Fund's Advisor, employs a fundamental, bottom-up research driven approach to identify companies for investment by the Core Equity Fund. The Advisor seeks to identify companies that it believes are positioned to benefit from one or more of the following: (i) shifts in industry spending, government spending and consumer trends; (ii) gains in market share from innovative products and strong intellectual property; and (iii) cyclical trends in the industry in which they operate and capable management that can take advantage of those trends. At times, the Core Equity Fund's assets may be invested in securities of relatively few industries or sectors.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Core Equity Fund is set forth below. Before you decide whether to invest in the Core Equity Fund, carefully consider these risk factors associated with investing in the Core Equity Fund, which may cause investors to lose money. There can be no assurance that the Core Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Core Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Core Equity Fund participate, or factors relating to specific companies in which the Core Equity Fund invests.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Core Equity Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs, EDRs and GDRs. Unsponsored ADRs, EDRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, and the issuing bank may deduct custody, foreign currency exchange, and other fees from the payment of dividends.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Preferred Stock Risk. Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. The market value of preferred stock is subject to company-specific and market risks applicable generally to equity securities and is also sensitive to changes in the company's creditworthiness, the ability of the company to make payments on the preferred stock, and changes in interest rates, typically declining in value if interest rates rise. Convertible preferred stock allows the holder to convert the preferred shares into a fixed number of common shares, usually after a predetermined date. Like preferred stock, convertible preferred stock generally pays a dividend at a specified rate and has preference over common stock in the payment of dividends but ranks behind bonds, including convertible bonds, in priority upon liquidation.

Real Estate Investment Trust (REIT) Risk. The Core Equity Fund's investment in REITs will subject the Core Equity Fund to risks similar to those associated with direct ownership of real estate, including losses from casualty or condemnation, and changes in local and general economic, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses.

Sector Focus Risk. The Core Equity Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Warrants and Rights Risk. Warrants and rights may lack a liquid secondary market for resale. The prices of warrants and rights may fluctuate as a result of speculation or other factors. Warrants and rights can provide a greater potential for profit or loss than an equivalent investment in the underlying security. Prices of warrants and rights do not necessarily move in tandem with the prices of their underlying securities and therefore are highly volatile and speculative investments. If a warrant or right expires without being exercised, the Fund will lose any amount paid for the warrant or right.

Performance

The Fund is new and does not have a full calendar year performance record to compare against other mutual funds or broad measures of securities market performance such as indices. Performance information will be available after the Fund has been in operation for one calendar year.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Global Opportunities Fund primarily invests its assets in equity securities that are listed on an exchange or that are otherwise publicly traded in the United States or in a foreign country. However, the Global Opportunities Fund may also invest in a variety of other instruments traded in U.S. and foreign markets, including, but not limited to, fixed income securities, convertible securities, and unlisted equity securities. The Global Opportunities Fund may also invest in exchange-traded funds ("ETFs"). ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

Under normal market conditions, the Global Opportunities Fund invests in at least three different countries, including emerging market countries, with at least 40% of its net assets invested in securities of issuers located outside the United States. The Global Opportunities Fund's investments in foreign securities may include investments through American, European and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). Depository receipts represent interests in foreign securities held on deposit by banks.

The Global Opportunities Fund does not limit the types of companies in which it seeks to invest its assets based on market capitalization.

The Global Opportunities Fund's investments in fixed income securities may be of any maturity and credit quality, including securities rated below investment grade (commonly referred to as "junk" bonds). The Global Opportunities Fund generally holds its investments for the long term.

In selecting investments for the Global Opportunities Fund, the Fund's investment advisor (Aristotle Capital Management, LLC) employs a fundamental, bottom-up approach. The Advisor focuses first on the quality of a company's business and then considers whether the company's securities are available at an attractive price.

In addition, the Global Opportunities Fund may pursue tactical investment strategies from time to time in order to seek favorable returns on securities that the Advisor believes are over-valued based on its assessment of their prices. These tactical strategies may include, for example, short sales, investments in warrants, futures, forward contracts, distressed debt, preferred securities, and convertible securities, and purchase and sale of options, based on the Advisor's assessment of the fair value of the instrument or, as applicable, the underlying or related instrument (e.g., the stock on which an option is purchased). The Global Opportunities Fund may also pursue merger arbitrage opportunities in an effort to profit from any discount in the price of a target company's stock prior to the closing of a merger.

The Global Opportunities Fund generally seeks favorable performance relative to its benchmark, the MSCI All Country World Index (net). However, the Advisor is not constrained by the composition of the MSCI All Country World Index in selecting investments for the Global Opportunities Fund.

Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Global Opportunities Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objective.

Asset Segregation Risk. As a series of an investment company registered with the SEC, the Fund must segregate liquid assets, or engage in other measures to "cover" open positions with respect to certain kinds of derivatives and short sales. The Global Opportunities Fund may incur losses on derivatives and other leveraged investments (including the entire amount of the Fund's investment in such investments) even if they are covered.

Convertible Securities Risk. Convertible securities are subject to market and interest rate risk and credit risk. When the market price of the equity security underlying a convertible security decreases the convertible security tends to trade on the basis of its yield and other fixed income characteristics, and is more susceptible to credit and interest rate risks. When the market price of such equity security rises, the convertible security tends to trade on the basis of its equity conversion features and be more exposed to market risk. Convertible securities are typically issued by smaller capitalized companies with stock prices that may be more volatile than those of other companies.

Credit Risk. If an issuer or guarantor of a debt security held by the Global Opportunities Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Global Opportunities Fund's portfolio will typically decline. Junk bonds have a higher risk of default than other fixed income securities and are considered predominantly speculative.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. Dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. Major types of derivatives include futures, options, swaps and forward contracts. Using derivatives can have a leveraging effect and increase fund volatility. Derivatives transactions can be highly illiquid and difficult to unwind or value, and changes in the value of a derivative held by the Fund may not correlate with the value of the underlying instrument or the Fund's other investments. Many of the risks applicable to trading the instruments underlying derivatives are also applicable to derivatives trading. However, additional risks are associated with derivatives trading that are possibly greater than the risks associated with investing directly in the underlying instruments. These additional risks include, but are not limited to, illiquidity risk and counterparty credit risk. For derivatives that are required to be cleared by a regulated clearinghouse, other risks may arise from the Fund's relationship with a brokerage firm through which it submits derivatives trades for clearing, including in some cases from other clearing customers of the brokerage firm.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Equity Risk. The value of the equity securities held by the Global Opportunities Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Global Opportunities Fund participate, or factors relating to specific companies in which the Fund invests.

ETF Risk. Investing in an ETF will provide the Global Opportunities Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Global Opportunities Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Global Opportunities Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and GDR. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

High Yield ("Junk") Bond Risk. High yield bonds are debt securities rated below investment grade (often called "junk bonds"). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Leveraging Risk. Certain Fund transactions, including entering into futures contracts and taking short positions in financial instruments, may give rise to a form of leverage. Leverage can magnify the effects of changes in the value of the Global Opportunities Fund's investments and make the Fund more volatile. Leverage creates a risk of loss of value on a larger pool of assets than the Global Opportunities Fund would otherwise have had, potentially resulting in the loss of all assets. The Global Opportunities Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Liquidity Risk. The Global Opportunities Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Global Opportunities Fund's investments. Illiquid assets may also be difficult to value.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Global Opportunities Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases between the date of the short sale and the date on which the Global Opportunities Fund replaces the security or other instrument borrowed to make the short sale, the Global Opportunities Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

The International Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the International Equity Fund's portfolio turnover rate was 10% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the International Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in publicly traded equity securities or depository receipts of companies organized, headquartered or doing a substantial amount of business outside of the United States. Aristotle Capital Management, LLC, the International Equity Fund's Advisor, considers a company that has at least 50% of its assets located outside the United States or derives at least 50% of its revenue from business outside the United States as doing a substantial amount of business outside the United States. The International Equity Fund generally invests in securities of companies located in different regions and in at least three different countries. The International Equity Fund intends to invest no more than 20% of its total assets in companies organized, headquartered or doing a substantial amount of business in emerging market countries under normal market conditions.

The International Equity Fund's investments in equity securities may include common stocks, preferred stocks, warrants and rights. The International Equity Fund's investments in depository receipts may include American, European, and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets. The International Equity Fund may invest in companies of any market capitalization.

In pursuing the International Equity Fund's investment objective, the Advisor employs a fundamental, bottom-up research driven approach to identify companies for investment by the Fund. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value. The Advisor seeks to identify high quality companies by focusing on the following attributes: attractive business fundamentals, strong financials, experienced, motivated company management, and high and/or consistently improving market position, return on invested capital or operating margins.

The International Equity Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund.

Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing and you could lose your money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the International Equity Fund, which may cause investors to lose money. There can be no assurance that the International Equity Fund will achieve its investment objective.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. Dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Equity Risk. The value of the equity securities held by the International Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the International Equity Fund participate, or factors relating to specific companies in which the Fund invests.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the International Equity Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and GDRs. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Non-Diversification Risk. The International Equity Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Strategic Credit Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities. The types of debt securities in which the Fund may invest include, but are not limited to, corporate bonds, notes and debentures of U.S. and non-U.S. issuers, and bank loans of U.S. and non-U.S. corporate issuers. The Strategic Credit Fund's investments in foreign securities include securities in both developed and emerging markets.

The Strategic Credit Fund may invest in debt securities of any maturity and credit quality. Under normal market conditions, the Fund's Advisor, Aristotle Credit Partners, LLC, expects that the Fund will generally invest in investment grade corporate bonds as well as high yield bonds and in bank loans that are generally both rated in the "B" and "BB" quality tiers of the high yield categories by nationally recognized securities rating organizations at the time of purchase or, if unrated, determined by the Advisor to be of comparable credit quality. However, the Strategic Credit Fund may also invest in corporate debt investments rated below "B". The Advisor believes these securities with these credit ratings provide the optimal risk-adjusted performance over a market cycle. Investment grade securities are those rated in the Baa3 or higher categories by Moody's Investors Service, Inc. ("Moody's"), or in the BBB- or higher categories by Standard & Poor's, a division of McGraw Hill Companies Inc. ("S&P"), or Fitch Ratings Ltd. ("Fitch") or, if unrated by S&P, Moody's or Fitch, determined by the Advisor to be of comparable credit quality. High yield bonds, commonly referred to as "junk bonds" and bank loans, are generally rated below investment grade by Moody's, S&P, or Fitch.

In pursuing the Strategic Credit Fund's investment objectives, the Advisor uses a disciplined investment approach that integrates a top-down macroeconomic environment assessment with a bottom-up fundamental credit analysis. The Advisor seeks to identify and invest in securities of companies with stable or improving financial profiles.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Strategic Credit Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Strategic Credit Fund will achieve its investment objective.

Bank Loan Risk. The Strategic Credit Fund's investments in assignments of bank loans may create substantial risk. Although the Strategic Credit Fund expects it will invest in senior and secured bank loans, the Fund may invest in unsecured or subordinated loans. In addition, the Fund may invest in secured and unsecured participations in bank loans. These bank loans will generally be rated below investment grade. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Strategic Credit Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of the underlying borrower. If the Strategic Credit Fund invests in a bank loan through a participation, the Fund will also be exposed to the credit risk of financial institution selling the participation to the Fund as well as the credit risk of the underlying borrower. The market for bank loan may not be highly liquid and the Fund may have difficulty selling them. Bank loans have similar risks to high yield bonds and are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing bank loans are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings. Unlike senior secured loans which have a priority claim on the borrower's assets and are secured with the borrower's assets and/or equity, unsecured or subordinated loans may carry greater risk since they will not have a priority claim and may not be secured by the borrower's assets.

Credit Risk. If an issuer or guarantor of a debt security held by the Strategic Credit Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund's portfolio will typically decline. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

Emerging Market Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed economic, political and legal systems than those of more developed countries. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Extension Risk. If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market which may cause the value of the securities to fall.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include American Depository Receipts ("ADRs") and Global Depository Receipts ("GDRs"). Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

High Yield ("Junk") Bond Risk. High yield bonds are debt securities rated below investment grade (often called "junk bonds"). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment-grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Interest Rate Risk. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, with longer-term securities being more sensitive than shorter-term securities. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Generally, the longer the maturity and duration of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund's income. Changes in governmental policy, rising inflation rates, and general economic developments, among other factors, could cause interest rates to increase and could have a substantial and immediate effect on the values of the Fund's investments. In addition, a potential rise in interest rates may result in periods of volatility and increased redemptions that might require the Fund to liquidate portfolio securities at disadvantageous prices and times.

Liquidity Risk. The Strategic Credit Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Fund's investments. Illiquid assets may also be difficult to value.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Prepayment or Call Risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Strategic Credit Fund may not benefit from the rise in market price that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Strategic Credit Fund may also lose any premium it paid on the security.

Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds and thus will be more susceptible to negative events affecting those sectors. For example, as of December 31, 2017, 25.6% of the Strategic Credit Fund's assets were invested in the consumer discretionary sector. Companies in the consumer discretionary sector may be adversely impacted by fluctuations in supply and demand, changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending.

Valuation Risk. The sales price the Strategic Credit Fund could receive for any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued by the Fund using a fair value methodology. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the Fund had not fair-valued the security or had used a different valuation methodology.

The Value Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Value Equity Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Value Equity Fund's portfolio turnover rate was 14% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Value Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities. The Value Equity Fund's investments in equity securities may include common stocks, depository receipts, and exchange-traded funds ("ETFs") that invest primarily in equity securities. Depository receipts represent interests in foreign securities held on deposit by banks. ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

The Value Equity Fund seeks to meet its investment objective by investing primarily in equity securities of domestic and foreign issuers that are listed on a U.S. exchange or that are otherwise publicly traded in the United States but may invest up to 20% of its total assets in American Depository Receipts and Global Depository Receipts ("ADRs" and "GDRs", respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets.

In selecting investments for the Value Equity Fund, the Advisor employs a fundamental, bottom-up approach. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value and have a minimum market capitalization of $2 billion. The Advisor seeks to identify high quality businesses by focusing on companies with the following attributes: attractive business fundamentals; experienced, motivated company management; pricing power; sustainable competitive advantages; financial strength; and/or high or consistently improving market position, return on invested capital and operating margins.

The Value Equity Fund generally seeks favorable performance relative to its benchmark, the Russell 1000 Value Index. However, the Advisor is not constrained by the composition of the Russell 1000 Value Index in selecting investments for the Fund.

Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Value Equity Fund is set forth below. Before you decide whether to invest in the Value Equity Fund, carefully consider these risk factors associated with investing in the Value Equity Fund, which may cause investors to lose money. There can be no assurance that the Value Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Value Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Value Equity Fund participate, or factors relating to specific companies in which the Fund invests.

ETF Risk. Investing in an ETF will provide the Value Equity Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Value Equity Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs and Global Depository Receipts ("GDRs") Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends. Emerging markets tend to be more volatile than the markets of more mature economies and generally have less diverse and less mature economic structures and less stable political systems than those of developed countries.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors. For example, as of December 31, 2017, 24.5% of the Value Equity Fund's assets were invested in the financial sector. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others: government regulations of, or related to, the sector; governmental monetary and fiscal policies; economic, business or political conditions; credit rating downgrades; changes in interest rates; price competition; and decreased liquidity in credit markets. This sector has experienced significant losses and a high degree of volatility in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Small Cap Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities of small capitalization companies. Aristotle Capital Boston, LLC, the Small Cap Equity Fund's Advisor, considers small capitalization companies to be those companies that, at the time of initial purchase, have a market capitalization equal to or less than that of the largest company in the Russell 2000® Index during the most recent 12-month period (approximately $14.3 billion during the 12-month period ended December 31, 2017). The Russell 2000® Index is reconstituted annually. Because small capitalization companies are defined by reference to an index, the range of market capitalization of companies in which the Small Cap Equity Fund invests may vary with market conditions. Investments in companies that move above or below the capitalization range may continue to be held by the Small Cap Equity Fund in the Advisor's sole discretion. The Small Cap Equity Fund's investments in equity securities may include common stocks, depository receipts, and exchange traded-funds ("ETFs") that invest primarily in equity securities of small capitalization companies. Depository receipts represent interests in foreign securities held on deposit by banks. ETFs are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges.

The Small Cap Equity Fund seeks to meet its investment objective by investing primarily in equity securities of U.S. issuers but may invest up to 5% of its total assets in American Depository Receipts ("ADRs"). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks.

In pursuing the Small Cap Equity Fund's investment objective, the Advisor employs a fundamental, bottom-up research driven approach to identify companies for investment by the Small Cap Equity Fund. The Advisor focuses on those companies that it believes have high quality businesses that are undervalued by the market relative to what the Advisor believes to be their fair value. The Advisor seeks to identify high quality businesses by focusing on companies with the following attributes: disciplined business plans; attractive business fundamentals; sound balance sheets; financial strength; experienced, motivated company management; reasonable competition; and/or a record of long-term value creation.

The Fund generally seeks favorable performance relative to its benchmark, the Russell 2000 Index. However, the Advisor is not constrained by the composition of the Russell 2000 Index in selecting investments for the Fund.

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Small Cap Equity Fund is set forth below. Before you decide whether to invest in the Small Cap Equity Fund, carefully consider these risk factors associated with investing in the Small Cap Equity Fund, which may cause investors to lose money. There can be no assurance that the Small Cap Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Small Cap Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Small Cap Equity Fund invests.

ETF Risk. Investing in an ETF will provide the Small Cap Equity Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities.

The Small Cap Equity Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs. Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Small-Cap Company Risk. The securities of small-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security's inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Core Equity Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Core Equity Fund's performance. During the period March 31, 2017 (commencement date) through December 31, 2017, the Fund's portfolio turnover rate was 22% of the average value of its portfolio.

Expense Example Narrative [Text Block]

This example is intended to help you compare the cost of investing in the Core Equity Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Core Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Core Equity Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Core Equity Fund invests at least 80% of its net assets (including amounts borrowed for investment purposes) in equity securities. The Core Equity Fund's investments in equity securities may include common stocks, preferred stocks, convertible preferred stocks, depository receipts, shares of publicly-traded real estate investment trusts ("REITs"), warrants and rights. The Core Equity Fund's investments in depository receipts may include American, European, and Global Depository Receipts ("ADRs," "EDRs," and "GDRs," respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets. Although the Core Equity Fund may invest in companies of any market capitalization and from any country, it invests primarily in large U.S. companies.

In pursuing the Core Equity Fund's investment objective, Aristotle Atlantic Partners, LLC, the Core Equity Fund's Advisor, employs a fundamental, bottom-up research driven approach to identify companies for investment by the Core Equity Fund. The Advisor seeks to identify companies that it believes are positioned to benefit from one or more of the following: (i) shifts in industry spending, government spending and consumer trends; (ii) gains in market share from innovative products and strong intellectual property; and (iii) cyclical trends in the industry in which they operate and capable management that can take advantage of those trends. At times, the Core Equity Fund's assets may be invested in securities of relatively few industries or sectors.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Core Equity Fund is set forth below. Before you decide whether to invest in the Core Equity Fund, carefully consider these risk factors associated with investing in the Core Equity Fund, which may cause investors to lose money. There can be no assurance that the Core Equity Fund will achieve its investment objective.

Equity Risk. The value of the equity securities held by the Core Equity Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Core Equity Fund participate, or factors relating to specific companies in which the Core Equity Fund invests.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the values of the Core Equity Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs, EDRs and GDRs. Unsponsored ADRs, EDRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, and the issuing bank may deduct custody, foreign currency exchange, and other fees from the payment of dividends.

Large-Cap Company Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund's Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Preferred Stock Risk. Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. The market value of preferred stock is subject to company-specific and market risks applicable generally to equity securities and is also sensitive to changes in the company's creditworthiness, the ability of the company to make payments on the preferred stock, and changes in interest rates, typically declining in value if interest rates rise. Convertible preferred stock allows the holder to convert the preferred shares into a fixed number of common shares, usually after a predetermined date. Like preferred stock, convertible preferred stock generally pays a dividend at a specified rate and has preference over common stock in the payment of dividends but ranks behind bonds, including convertible bonds, in priority upon liquidation.

Real Estate Investment Trust (REIT) Risk. The Core Equity Fund's investment in REITs will subject the Core Equity Fund to risks similar to those associated with direct ownership of real estate, including losses from casualty or condemnation, and changes in local and general economic, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses.

Sector Focus Risk. The Core Equity Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors.

Small-Cap and Mid-Cap Company Risk. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Warrants and Rights Risk. Warrants and rights may lack a liquid secondary market for resale. The prices of warrants and rights may fluctuate as a result of speculation or other factors. Warrants and rights can provide a greater potential for profit or loss than an equivalent investment in the underlying security. Prices of warrants and rights do not necessarily move in tandem with the prices of their underlying securities and therefore are highly volatile and speculative investments. If a warrant or right expires without being exercised, the Fund will lose any amount paid for the warrant or right.
