LGOV First Trust Long Duration Opportunities ETF

Investment Objective

The First Trust EIP Carbon Impact ETF (the "Fund") seeks to achieve a competitive risk-adjusted total return balanced between dividends and capital appreciation.

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy and hold shares of the Fund. Investors purchasing and selling shares may be subject to costs (including customary brokerage commissions) charged by their broker, which are not reflected in the table below.

Shareholder Fees
(fees paid directly from your investment)

Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)

None

    

(1)	"Other Expenses" is an estimate based on the expenses the Fund expects to incur for the current fiscal year.

Example

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account customary brokerage commissions that you pay when purchasing or selling shares of the Fund in the secondary market.

The example assumes that you invest $10,000 in the Fund for the time periods indicated. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain at current levels. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$98	$305	$530	$1,176

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate 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 fiscal period August 19, 2019 (inception) through October 31, 2019, the Fund’s portfolio turnover rate was 3% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in the equity securities of companies identified by the Fund’s investment sub-advisor, Energy Income Partners, LLC (“EIP” or the “Sub-Advisor”), as having or seeking to have a positive carbon impact. The Sub-Advisor defines positive carbon impact companies as companies that reduce, have a publicly available plan to reduce, or enable the reduction of carbon and other greenhouse gas (“GHG”) emissions from the production, transportation, conversion, storage and use of energy. The companies in which the Fund invests will have demonstrated a commitment to positive carbon impact activities, as determined by the Sub-Advisor, based on its fundamental research and review of public documents, such as regulatory filings and investor and public communications. Examples of positive carbon impact activities include investing capital in activities and technologies with lower GHG emissions, such as wind and solar power generation, or by replacing coal fired power generation facilities with natural gas power generation facilities.

In addition, natural gas pipeline companies that supply natural gas power generation facilities have a positive carbon impact by enabling the use of wind and solar power because natural gas power generation facilities serve to back-up and compensate for the intermittent availability of wind and solar power. Other examples of companies having a positive carbon impact include those making investments to reduce methane leaks from the processing, transport and distribution of natural gas, investments in the capture, transportation and sequestration of carbon dioxide or investments in grid-level battery storage or fuel cells.

The Sub-Advisor conducts the following four-step process when selecting investments for the Fund:

1.

Define a universe of potential investments from companies operating in the following industries, including but not limited to: utilities; natural gas pipelines; manufacturers, contracted developers and/or owners of renewable energy; and other companies that operate and/or provide services in support of activities such as renewable energy equipment, energy storage, carbon capture and sequestration, fugitive methane abatement and energy transmission and distribution equipment. These companies may exhibit a higher than average payout ratio supported by stable cash flows derived from long-term contracts, a regulated cost-of-service pricing scheme with inflation adjustments or cost pass-through protections.

2.

Eliminate companies that in the Sub-Advisor’s view have no plans to reduce emissions and have a strategic commitment to any of the following activities that (individually, and not collectively) constitutes more than a de minimis amount of annual enterprise-wide earnings before interests, taxes, depreciation and amortization (“EBITDA”):

a.	coal production;
b.	crude oil exploration and production; or
c.	transportation, storage or delivery of crude oil.

3.	Identify among the remaining companies those that, in the Sub-Advisor’s view, currently or plan to:

a.	reduce carbon and other GHG emissions within their own operations;
b.	facilitate reduction of carbon and other GHG emissions across the broader market, such as through the displacement of more carbon-intensive fuels such as coal or oil; or
c.	facilitate the increased use of renewable resources across the broader market such as by balancing the variable production of wind and solar power with fully available natural gas generated power or through the storage of electricity.

4.

The Sub-Advisor then selects securities for the Fund’s portfolio from the remaining eligible securities based upon its holistic assessment of both quantitative and qualitative attributes associated with the remaining securities. Such quantitative attributes include, but are not limited to, operating metrics and financial metrics, such as stability of cash flows and the strength of the balance sheet. Relevant qualitative attributes include, but are not limited to, the Sub-Advisor’s confidence in the company’s management team, the sustainability of a company’s business model and the competitiveness of a company’s assets. In its assessment of quality, the Sub-Advisor will not consider any measures of valuation. No one quantitative or qualitative attribute is dispositive in the Sub-Advisor’s security selection process, but rather, when considered cumulatively, such attributes help inform the Sub-Advisor’s investment decisions in light of market conditions and the Sub-Advisor’s own experience. In determining security weights, the Sub-Advisor balances each position’s expected rate of return against risks, position size and diversification considerations and the Fund’s portfolio limitations.

The Fund’s investments will be concentrated in the industries constituting the energy infrastructure sector. These companies principally include: utilities; natural gas pipeline companies; manufacturers, contracted developers and/or owners of renewable energy; and other companies that derive the majority of their earnings from manufacturing, operating or providing services in support of infrastructure assets and/or infrastructure activities such as renewable energy equipment, energy storage, carbon capture and sequestration, fugitive methane abatement and energy transmission and distribution equipment. The Fund will generally not invest in companies comprising the following industries: coal production, oil exploration and production, or crude oil storage, transportation and delivery. The Fund’s portfolio will be principally composed of equity securities, including common stock, depositary receipts, and units issued by master limited partnerships (“MLPs”). Such securities may be issued by small, mid and large capitalization companies operating in developed market countries. As of January 31, 2020, the Fund had significant investments in energy and utility companies, although this may change from time to time. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.

The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”).

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund’s investment objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CANADA RISK. The Fund is subject to certain risks specifically associated with investments in the securities of Canadian issuers. The Canadian economy is heavily dependent on the demand for natural resources and agricultural products. Canada is a major producer

of commodities such as forest products, metals, agricultural products, and energy related products like oil, gas, and hydroelectricity. Accordingly, a change in the supply and demand of these resources, both domestically and internationally, can have a significant effect on Canadian market performance. Canada is a top producer of zinc and uranium and a global source of many other natural resources, such as gold, nickel, aluminum, and lead. Conditions that weaken demand for such products worldwide could have a negative impact on the Canadian economy as a whole. Changes to the U.S. economy may significantly affect the Canadian economy because the United States is Canada’s largest trading partner and foreign investor. These and other factors could have a negative impact on the Fund and its investments in Canada.

CONCENTRATION RISK. The Fund is concentrated in the industries comprising the energy infrastructure sector. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A concentration makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is not so concentrated.

CYBER SECURITY RISK. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

ENERGY COMPANIES RISK. The success of energy companies may be cyclical and highly dependent on energy prices. The market value of securities issued by energy companies may decline for many reasons, including, among other things, changes in the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production of energy sources, exchange rates, interest rates, economic conditions, tax treatment, energy conservation efforts, increased competition and technological advances. Energy companies may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of doing business and limit the earnings of these companies. A significant portion of the revenues of energy companies may depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of energy companies. Energy companies may also operate in, or engage in transactions involving, countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

IMPACT INVESTING RISK. The Fund’s investment strategy limits the number of investment opportunities available to the Fund. Only securities issued by companies identified by the Sub-Advisor as seeking to reduce the carbon impact of the production, transportation, conversion or storage of energy are eligible for inclusion in the Fund’s portfolio. As a result, the Fund may underperform other funds that are not subject to such limits. In addition, companies selected for inclusion in the Fund may not ultimately undertake, or be successful in, their efforts to reduce the carbon impact of the production, transportation, conversion or storage of energy.

INDEX CONSTITUENT RISK. The Fund may be a constituent of one or more indices. As a result, the Fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund’s shares, the size of the Fund and the market volatility of the Fund. Inclusion in an index could increase demand for the Fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result,

the Fund’s net asset value could be negatively impacted and the Fund’s market price may be below the Fund’s net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in the Fund’s shares.

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline.

LIQUIDITY RISK. The Fund may hold certain investments that may be subject to restrictions on resale, trade over-the-counter or in limited volume, or lack an active trading market. Accordingly, the Fund may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value.

MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective.

MARKET MAKER RISK. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments.

MLP RISK. Investments in securities of MLPs involve certain risks different from or in addition to the risks of investing in common stocks. MLP common units can be affected by macro-economic factors and other factors unique to the partnership or company and the industry or industries in which the MLP operates. Certain MLP securities may trade in relatively low volumes due to their smaller capitalizations or other factors, which may cause them to have a high degree of price volatility and illiquidity. The structures of MLPs create certain risks, including, for example, risks related to the limited ability of investors to control an MLP and to vote on matters affecting the MLP, risks related to potential conflicts of interest between an MLP and the MLP's general partner, the risk that an MLP will generate insufficient cash flow to meet its current operating requirements, the risk that an MLP will issue additional securities or engage in other transactions that will have the effect of diluting the interests of existing investors, and risks related to the general partner's right to require unit-holders to sell their common units at an undesirable time or price. On March 15, 2018, the Federal Energy Regulatory Commission (“FERC”) changed its long-standing tax allowance policy which no longer permits MLPs to include in their cost of service an income tax allowance. This has had a negative impact on the performance of some MLPs affected by this decision. This policy change and any similar policy changes in the future could adversely impact an MLP’s business, financial condition, results of operations and cash flows and ability to pay cash distributions or dividends.

MLP TAX RISK. The Fund’s ability to meet its investment objective relies in part upon the level of taxable income it receives from the MLPs in which it invests, a factor over which the Fund has no control. The benefit the Fund derives from its investment in MLPs is largely dependent on their being treated as partnerships for U.S. federal income tax purposes. Partnerships do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or a change in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in the MLP being required to pay U.S. federal income tax (as well as state and local income taxes) on its taxable income at the applicable corporate tax rate. This would have the effect of reducing the amount of cash available for distribution by an MLP and could result in a significant reduction in the value of the Fund’s investment. The classification of an MLP as a corporation for U. S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP and causing any such distributions received by the Fund to be taxed as dividend income to the extent of the MLP’s current or accumulated earnings and profits. To the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in the amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests. Furthermore, any return of capital distribution received from an MLP may require the Fund to restate the character of its distributions and amend any shareholder tax reporting previously issued.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number

of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. The Fund’s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained.

SMALLER COMPANIES RISK. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

TRADING ISSUES RISK. Although the shares of the Fund are listed for trading on the Exchange, there can be no assurance that an active trading market for such shares will develop or be maintained. Further, secondary markets may be subject to irregular trading activity and wide bid-ask spreads (which may be especially pronounced for smaller funds). Trading in shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. Market makers are under no obligation to make a market in the Fund’s shares, and authorized participants are not obligated to submit purchase or redemption orders for Creation Units. In the event market makers cease making a market in the Fund's shares or authorized participants stop submitting purchase or redemption orders for Creation Units, Fund shares may trade at a larger premium or discount to their net asset value. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small or the Fund does not have enough shareholders.

UTILITY COMPANIES RISK. Utility companies include companies producing or providing gas, electricity or water. These companies are subject to the risk of the imposition of rate caps, increased competition due to deregulation, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects counterparty risk, the limitations on operations and increased costs and delays attributable to environmental considerations and the capital market’s ability to absorb utility debt. In addition, taxes, government regulation, domestic and international politics, price and supply fluctuations, volatile interest rates and energy conservation may negatively affect utility companies.

Purchase and Sale of Fund Shares

The Fund issues and redeems shares on a continuous basis, at net asset value, only in Creation Units consisting of 50,000 shares. The Fund’s Creation Units are generally issued and redeemed in-kind for securities in which the Fund invests and, in certain circumstances, for cash, and only to and from broker-dealers and large institutional investors that have entered into participation agreements. Individual shares of the Fund may only be purchased and sold on NYSE Arca and other eligible securities exchanges through a broker-dealer. Shares of the Fund trade on NYSE Arca at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount).
