WisdomTree CEO Jonathan Steinberg commented, “I am very pleased with our accelerating top-line growth as a result of higher asset levels and growing market share of net inflows in the second quarter, driven in part by continued product innovation and the diversification of our multi-asset class ETF platform. In fact, according to InvestmentNews WisdomTree launched the top two most successful ETFs of the first half of 2011 in terms of assets gathered.”

Mr. Steinberg continued, “While 2010 represented our strongest year of inflows with $3.1 billion, as of today we have already surpassed this number, demonstrating consistent and accelerating organic growth.

Second Quarter Financial Discussion

Revenues

Total revenues for the quarter increased 78.7% to a record $16.7 million as compared to the second quarter of 2010 and increased 15.0% from the first quarter of 2011. These increases were primarily due to higher average assets under management from strong net ETF inflows. Average ETF assets under management were $12.1 billion in the second quarter of 2011, as compared to $6.8 billion in the second quarter of 2010 and $10.3 billion in the first quarter of 2011. The average fee earned during the second quarter of 2011 decreased to 0.55% from 0.56% in the first quarter of 2011 due to a decrease in the fee charged for our India ETF from 0.88% to 0.83%. As compared to the second quarter of 2010, our average fee increased from 0.54% due to higher average assets and net inflows into our emerging market funds.

Expenses

Total expenses increased 42.9% to $16.0 million from $11.2 million in the second quarter of 2010 and increased 11.5% from $14.4 million in the first quarter of 2011. These increases were primarily due to higher fund related costs, marketing and advertising, and third party sharing arrangements.

Year-to-Date Results

Total revenues increased $13.2 million or 72.9% to $31.2 million for the six months ended June 30, 2011 as compared to $18.1 million in 2010. This increase was primarily due to higher average assets under management, which increased 73.5% to $11.3 billion, which resulted from $3.0 billion of net ETF inflows, as well as higher average ETF advisory fees.

4

Total expenses increased $6.9 million or 29.3% to $30.4 million for the six months ended June 30, 2011 as compared to $23.5 million in 2010. This increase was primarily due to higher fund management and administration expenses due to higher average asset balances, higher third-party sharing arrangements due to higher asset balances in our currency and fixed income ETFs, and higher marketing and advertising and sales and business development expenses to support our growth.

As of June 30, 2011, WisdomTree had total assets of $32.6 million, which consisted primarily of cash and cash equivalents of $16.4 million and investments of $8.2 million. WisdomTree has no debt.
