Material U.S. Federal Income Tax Consequences for Cedar Fair Unitholders Cedar Fair First Merger, page 148 4. We note your discussion of U.S. federal income tax consequences in this section related to the Cedar Fair First Merger. Item 601(b)(8) of Regulation S-K requires you to file a tax opinion where the tax consequences are material to an investor and a representation as to the tax consequences is set forth in the filing. It appears that a tax opinion would be required since the discussion includes tax consequences that would be material to investors, i.e. that Cedar Fair U.S. holders will recognize no gain or loss on such exchange. Please revise this section accordingly and file a tax opinion. For guidance, please refer to Section III of Staff Legal Bulletin No. 19 dated October 14, 2011.
