Fair Value Measurement

The Fund discloses the fair value of its investments in a hierarchy that distinguishes between: (i) market participant assumptions developed based on market data obtained from sources independent of the Fund (observable inputs) and (ii) the Fund’s own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the hierarchy are as follows:

• Level 1 — Quoted prices in active markets for identical assets.

• Level 2 — Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

• Level 3 — Significant unobservable inputs (including each Fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the valuations as of October 31, 2019, based upon the three levels defined above:

ARK Fintech Innovation ETF	Level 1		Level 2		Level 3		Total

2. Significant Accounting Policies

These Schedules of Investments are prepared in accordance with accounting principles generally accepted in the United States of America (‘‘U.S. GAAP’’), which require management to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amount of increase and decrease in net assets from operations during the fiscal period. Actual amounts could differ from these estimates. The Trust is an investment company and follows the investment company accounting standards and reporting guidance under Financial Accounting Standards Board (FASB) Accounting Standard Codification (“ASC”) Topic 946, ‘‘Financial Services — Investment Companies’’. The following summarizes the significant accounting policies of the Funds:

Investment Valuation

The values of each Fund’s securities are based on such securities’ closing prices on the principal market on which the securities are traded. Such valuations would typically be categorized as Level 1 in the fair value hierarchy. If a security’s market price is not readily available or does not otherwise accurately reflect the market value of such security, the security will be fair valued by ARK Investment Management LLC (‘‘Adviser”) in accordance with the Trust’s valuation policies and procedures that were approved by the Board of Trustees of the Trust (‘‘Board’’). Each Fund may use fair value pricing in a variety of circumstances, including but not limited to, situations when the value of a Fund’s security has been materially affected by events occurring after the close of the market on which such security is principally traded (such as a corporate action or other news that may materially affect the price of such security) or trading in such security has been suspended or halted. Such valuations would typically be categorized as Level 2 or Level 3 in the fair value hierarchy. Fair value pricing involves subjective judgments and it is possible that a fair value determination for a security could be materially different than the value that could be realized upon the sale of such security.

3. Investment Concentration

Concentration Risk: The ARK Genomic Revolution ETF will be concentrated in securities of issuers having their principal business activities in any industry or group of industries in the health care sector, including issuers having their principal business activities in the biotechnology industry. The ARK Industrial Innovation ETF will be concentrated in securities of issuers having their principal business activities in groups of industries in the industrials and information technology sectors, although it will not concentrate in any specific industry. The ARK Web x.0 ETF will be concentrated in securities of issuers having their principal business activities in the Internet information provider and catalog and mail order house industry. The ARK Fintech Innovation ETF will be concentrated in securities of issuers having their principal business activities in the communication, technology and financials group of industries. The 3D Printing ETF and the ARK Israel Innovative Technology ETF may each invest 25% or more of the value of its respective net assets in securities of issuers in any one industry or group of industries if the applicable index that the Fund replicates concentrates in an industry or group of industries. This concentration limit does not apply to securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. The ARK Innovation ETF will not be concentrated in any industry.

As of October 31, 2019, the ARK Genomic Revolution ETF had more than 25% of its assets invested in the biotechnology industry. To the extent a Fund’s holdings are concentrated in a particular industry or group of industries, adverse market conditions affecting those industries may have a more significant impact on the Fund than they would on a Fund investing in a broader range of securities and the value of the Fund’s shares may fluctuate more than shares of a fund investing in a broader range of securities.

The Funds’ prospectuses contain additional information regarding the risks associated with an investment in a Fund.
