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 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. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is an actively managed exchange-traded fund (“ETF”) that invests primarily in dividend-paying U.S.-listed equity securities of small capitalization companies. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in (i) small-capitalization companies and (ii) dividend-paying securities (i.e., equity securities that have paid a dividend in the prior 12 calendar months). The Fund defines a small-capitalization company as an issuer whose market capitalization at the time of purchase is within the range of the market capitalizations of the companies included in the Russell 2000® Index. The equity securities held by the Fund may include common stocks of U.S. companies, American Depositary Receipts (“ADRs”) (i.e., receipts evidencing ownership of foreign equity securities), and real estate investment trusts (“REITs”).

In selecting securities, Bahl & Gaynor, Inc., the Fund’s investment adviser (“Bahl & Gaynor” or the “Adviser”), employs a bottom‑up approach that considers, among other factors, a company’s historical earnings and dividend growth, as well as its balance sheet and cash flow generation, competitive position, and prospects for future cash flow and dividend growth. Weightings of individual sectors are based on the Adviser’s assessment of company fundamentals, valuations, and overall economic conditions. The Adviser targets companies that, in its judgement, have high-quality business models, strong dividend policies and dividend growth, competitive advantages, reasonable valuations, positive or increasing cash flows, and sound capital allocation policies or approaches. The Adviser believes that the securities identified using such strategies have the potential to provide improved downside protection relative to the broader small-cap equity market.

The Adviser generally sells a security when, in its opinion, one or more of the following occurs, among other reasons: (i) the Adviser believes the security’s dividend is no longer attractive relative to other opportunities, (ii) the Adviser believes the company’s fundamentals and/or management is deteriorating, (iii) the Adviser believes the company’s stock has become a greater weight of the

Fund’s portfolio than desired due to market appreciation or other factors, or (iv) the Adviser identifies a more attractive investment opportunity for the Fund.

While investing in a particular market sector is not a strategy of the Fund, its portfolio may be significantly invested in one or more sectors as a result of the security selection decisions made pursuant to its strategy. The Adviser anticipates that a significant portion of the Fund’s assets will consist of securities of companies in the financials, health care, and industrials sectors, although this may change from time to time.

The Fund is 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.

•Depositary Receipt Risk. Depositary Receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary Receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary Receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary Receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

Dividend-Paying Securities Risk. Investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. Securities of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time.

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 issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.

•ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility,

periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

◦Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

Foreign Markets Risk. Investments in ADRs that provide exposure to non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, the value of non-U.S. securities may be subject to risk of decline due to foreign currency fluctuations or to political or economic instability. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Non-Diversification Risk. The Fund is 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.

REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a U.S. REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income.

Bahl & Gaynor Small Cap Dividend ETF | Sector Risk Member

Prospectus [Line Items]

rr_ProspectusLineItems

Risk Narrative [Text Block]

rr_RiskTextBlock

•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.

◦Financials Sector Risk. This sector, which includes banks, insurance companies, and financial service firms, can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and fallout from the housing and sub-prime mortgage crisis. Banks, in particular, are subject to volatile interest rates, severe price competition, and extensive government oversight and regulation, which may limit certain economic activities available to banks, impact their fees and overall profitability, and establish capital maintenance requirements. In addition, banks may have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry. Insurance companies are subject to similar risks as banks, including adverse economic conditions, changes in interest rates, increased competition and government regulation, but insurance companies are more at risk from changes in tax law, government imposed premium rate caps, and catastrophic events, such as earthquakes, floods, hurricanes and terrorist acts. This sector has experienced significant losses in the recent past, and the impact of higher interest rates, 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. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in the financial sector and have caused significant losses.

◦Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines, an increased emphasis on the delivery of healthcare through outpatient services, loss or impairment of intellectual property rights and litigation regarding product or service liability.

◦Industrials Sector Risk. The industrials sector can be significantly affected by, among other things, worldwide economic growth, supply and demand for specific products and services, rapid technological developments, international political and economic developments, environmental issues, tariffs and trade barriers, and tax and governmental regulatory policies. As the demand for, or prices of, industrials increase, the value of the Fund’s investments generally would be expected to also increase. Conversely, declines in the demand for, or prices of, industrials generally would be expected to contribute to

declines in the value of such securities. Such declines may occur quickly and without warning and may negatively impact the value of the Fund and your investment.
