Related Party Transactions [Abstract] |
Related Party Transactions | 12. Related Party Transactions The Company’s revenues are derived primarily from investment advisory agreements with related parties. Under these agreements, the Company has licensed to related parties the use of certain of its own indexes for the U.S. and Canadian WisdomTree ETFs and WisdomTree UCITS ETFs. The Board of Trustees and Board of Directors of the related parties are primarily responsible for overseeing the management and affairs of the U.S. and Canadian WisdomTree ETFs, Boost ETPs and WisdomTree UCITS ETFs for the benefit of their shareholders and have contracted with the Company to provide for general management and administration services. The Company is also responsible for certain expenses of the related parties, including the cost of transfer agency, custody, fund administration and accounting, legal, audit, and other non-distribution services, excluding extraordinary expenses, taxes and certain other expenses, which is included in fund management and administration on the Company’s Consolidated Statements of Operations. In exchange, the Company receives fees based on a percentage of the ETF average daily net assets. The advisory agreements may be terminated by the related parties upon notice.
