The increase in market share in December 2016 was due in part to an increase in volume from lower-priced market-on-close (MOC) orders associated with portfolio rebalancing. This contributed to a significant drop in overall average revenue per share during the month as compared to the third quarter of 2016.

International Trading ActivityThe average daily trading commissions in December 2016 in ITG’s Canadian, European and Asia Pacific businesses were up approximately 23% in U.S. dollar terms on a combined basis as compared to the third quarter of 2016.

These statistics are preliminary and may be revised in subsequent updates and public filings. Volume statistics are posted on the investor relations section of ITG’s website, investor.itg.com and are available via a downloadable spreadsheet file.
