Subsequent Event

On July 1, 2015, the Company merged three of its wholly owned subsidiaries (FCStone, LLC, INTL FCStone Partners LP, and FCC Investments, Inc.) into its wholly owned subsidiary, INTL FCStone Securities Inc, and renamed the surviving subsidiary INTL FCStone Financial Inc. INTL FCStone Financial is registered as a broker-dealer with FINRA and is registered as a futures commission merchant with the CFTC and NFA.

In connection with the aforementioned merger of wholly owned subsidiaries, the Company transferred its remaining available-for-sale investments, at fair value, to the trading category in accordance with the accounting requirements for Broker-Dealers. The July 1, 2015 transfer of securities results in $3.4 million, net of tax, of unrealized gains not previously recognized in earnings to be recognized in earnings immediately during the fourth quarter of fiscal 2015.
