1. Securities Valuation

The portfolio securities of AlphaMark Large Cap Growth Fund (the “Fund”) are valued as of the close of business of the regular session of trading on the New York Stock Exchange (normally 4:00 p.m., Eastern time). Securities, including common stocks, exchange-traded funds, rights and option contracts, which are traded on exchanges are valued on the basis of their last sales prices on the exchanges on which they are primarily traded, or, if not traded on a particular day, at the closing bid price. Securities quoted by NASDAQ are valued at the NASDAQ Official Closing Price or, if not traded on a particular day, at the last bid price as reported by NASDAQ. Securities traded in the over-the-counter market are valued at the last sale price, if available, otherwise, at the mean of the closing bid and ask prices. Fixed income securities are generally valued on the basis of prices provided by an independent pricing service. When using a quoted price and when the market for the security is considered active, the security will be classified as Level 1 within the fair value hierarchy (see below). Securities and other assets for which market quotations are not readily available or are considered to be unreliable due to significant market or other events are valued at their fair value as determined in good faith in accordance with consistently applied procedures established by and under the general supervision of the Board of Trustees and will be classified as Level 2 or 3 within the fair value hierarchy, depending on the inputs used.

Accounting principles generally accepted in the United States of America (“GAAP”) establish a single authoritative definition of fair value, set out a framework for measuring fair value and require additional disclosures about fair value measurements.

Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in the three broad levels listed below:

• Level 1 – quoted prices in active markets for identical securities

• Level 2 – other significant observable inputs

• Level 3 – significant unobservable inputs

The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety is determined based on the lowest level input that is significant to the fair value measurement.

Notes to Schedules of Investments (Continued)

The following is a summary of the inputs used to value the Fund's investments as of May 31, 2020:

Investments in Securities	Level 1		Level 2		Level 3		Total
Common Stocks	$	15,978,701	$	-	$	-	$	15,978,701
Exchange-Traded Funds		666,274		-		-		666,274

U.S. Treasury Obligations		-		1,499,444		-		1,499,444
Money Market Funds		2,723,349		-		-		2,723,349
Total	$	19,628,431	$	1,499,444	$	-	$	21,127,875

Other Financial Instruments	Level 1			Level 2		Level 3		Total
Written Call Option Contracts	$	(84,035	)	$	-	$	-	$	(84,035	)
Total	$	(84,035	)	$	-	$	-	$	(84,035	)

See the Fund’s Schedule of Investments for a listing of the common stocks and rights by sector and industry type. The Fund did not hold any assets or liabilities that were measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of or during the period ended May 31, 2020.

2. Investment Transactions

Investment transactions are accounted for on trade date. Realized gains and losses on investments sold are determined on a specific identification basis.

3. Federal Income Tax

The following information is computed on a tax basis for each item as of May 31, 2020:

Tax cost of portfolio investments	$	17,919,826
Gross unrealized appreciation	$	4,217,472
Gross unrealized depreciation		(1,093,458	)
Net unrealized appreciation	$	3,124,014

The difference between the federal income tax cost of portfolio investments and the Schedules of Investments cost is due to certain timing differences in the recognition of capital gains or losses under income tax regulations and GAAP. These “book/tax” differences are temporary in nature and are due to the tax deferral of losses on wash sales.
