Investment Objective

The Pacer US Cash Cows 100 ETF (the “Fund”) is an exchange traded fund that seeks to track the total return performance, before fees and expenses, of the Pacer US Cash Cows 100 Index (the “Index”).

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. The fees are expressed as a percentage of the Fund’s average net assets. This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of Fund shares.


Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.49%
Distribution and/or Service (12b-1) Fees	None
Other Expenses*	0.00%
Total Annual Fund Operating Expenses	0.49%

* Estimated for the current fiscal year.

Example

The following example is intended to help retail investors compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that such investors would incur over various periods if they were to invest $10,000 in the Fund for the time periods indicated and then redeem all of the shares at the end of those periods. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year	3 Years
$50	$157

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. Because the Fund is newly organized, portfolio turnover information is not yet available.

Principal Investment Strategies of the Fund

The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed by Index Design Group, an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).

The Index

The Index uses an objective, rules-based methodology to provide exposure to large and mid-capitalization U.S. companies with high free cash flow yields. Companies with high free cash flow yields are commonly referred to as “cash cows”.

The initial index universe is derived from the component companies of the Russell 1000 Index. The initial universe of companies is screened based on their average projected free cash flows and earnings (if available) over each of the next two fiscal years. Companies with no forward year estimates available for free cash flows or earnings will remain in the Index universe. Companies with negative average projected free cash flows or ear nings are removed from the Index universe. Additionally, financial companies, other than real estate investment trusts (“REITs”), are excluded from the Index universe.

The remaining companies are ranked by their free cash flow yield for the trailing twelve month period. The equity securities of the 100 companies with the highest free cash flow yield are included in the Index.

At the time of each rebalance of the Index, the companies included in the Index are weighted in proportion to their trailing twelve month free cash flow, and weightings are capped at 2% of the weight of the Index for any individual company. As of December 8, 2016, the companies included in the Index had a market capitalization of $1.48 billion to $598.3 billion. The index is reconstituted and rebalanced quarterly as of the close of business on the 3^rd Friday of March, June, September, and December based on data as of the 1^st Friday of the applicable rebalance month.

Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.

Enterprise Value (EV): A company’s market capitalization plus its debt and minus its cash and cash equivalents.

Free Cash Flow Yield: FCF / EV

The Fund’s Investment Strategy

Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index, but may, when the Adviser believes it is in the best interests of the Fund, use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole.

The Fund may also invest up to 20% of its assets in cash and cash equivalents, other investment companies, as well as securities and other instruments not included in the Index but which the Adviser believes will help the Fund track the Index.

The Fund will be considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

Principal Risks of Investing in the Fund

You can lose money on your investment in the Fund. The Fund is subject to the risks summarized below. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s prospectus entitled “Additional Information about the Principal Risks of Investing in the Funds.”

Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments may be concentrated accordingly. In such event, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, an industry or group of industries in which the Fund is concentrated may be out of favor and underperform other industries or groups of industries.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change.

High Portfolio Turnover Risk. At times, the Fund may have a portfolio turnover rate substantially greater than 100%. A high portfolio turnover rate would result in correspondingly greater transaction expenses, including brokerage commissions, dealer mark ups and other transaction costs, on the sale of securities and on reinvestment in other securities and may result in reduced performance and the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance.

Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of mid-capitalization companies underperform securities of other capitalization ranges or the market as a whole. Securities of smaller companies trade in smaller volumes and are often more vulnerable to market volatility than securities of larger companies.

New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it may experience greater tracking error to its Index than it otherwise would at higher asset levels, or it could ultimately liquidate.

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund will be considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as ETFs. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds. When the Fund invests in other investment companies, the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies.

Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in, the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.

n	Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

Consumer Discretionary Sector Risk. The Fund may invest in companies in the consumer discretionary sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Industrials Sector Risk. The Fund may invest in companies in the industrials sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The industrials sector may be affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Information Technology Sector Risk. The Fund may invest in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. The price of Fund shares, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

To the extent the Fund uses a representative sampling approach, it will hold a smaller number of securities than are in the Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in the Fund’s net asset value than would be the case if the Fund held all of the securities in the Index. Conversely, a positive development relating to an issuer of securities in the Index that is not held by the Fund could cause the Fund to underperform the Index. To the extent the assets in the Fund are smaller, these risks may be greater.

Management

Investment Adviser

Pacer Advisors, Inc. (the “Adviser”) serves as investment adviser to the Fund.

Portfolio Managers

The Fund employs a rules-based, passive investment strategy. The Adviser uses a committee approach to managing the Fund. Bruce Kavanaugh, Vice President of the Adviser, and Michael Mack, Investment Analyst for the Adviser, have primary responsibility for the day-to-day management of the Fund and have served as Fund portfolio managers since the Fund’s inception.

Buying and Selling Fund Shares

The Fund is an exchange traded fund (“ETF”). This means that shares of the Fund are listed on a national securities exchange, such as BATS BZX Exchange, Inc., and trade at market prices. Most investors will buy and sell shares of the Fund through brokers. Because Fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (premium) or less than NAV (discount).

The Fund issues and redeems shares at NAV only in large blocks of shares (“Creation Units”), which only institutions or large investors may purchase or redeem. Currently, Creation Units generally consist of 50,000 shares, though this may change from time to time. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities (the “Deposit Securities”) and/or a designated amount of U.S. cash that the Fund specifies each day.

Tax Information

Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an IRA or other tax-advantaged retirement account. Distributions may be taxable upon withdrawal from tax-deferred accounts.

Payments to Broker-Dealers and Other Financial Intermediaries.

If you purchase the Fund through a broker or other financial intermediary (such as a bank), the Adviser and its related companies may pay the intermediary for activities related to the marketing and promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your sales person to recommend the Fund over another investment. Ask your sales person or visit your financial intermediary’s website for more information.
