Total expenses increased 18.9% to $73.8 million over the comparable period. Excluding non-operating items related to our patent litigation, ETF shareholder proxy, initial exchange listing, and secondary offering, expenses increased 14.4% to $70.0 million from $61.2 million. This increase was primarily due to higher compensation and benefits related expenses due to higher accrued incentive compensation, stock based compensation, and expenses associated with higher headcount; higher fund management and administration expenses due to higher average asset balances; and higher marketing related expenses to support our growth.
As of December 31, 2012, WisdomTree had total assets of $63.4 million which consisted primarily of cash and cash equivalents of $41.2 million and investments of $11.0 million. The Company has no debt. There were approximately 126.6 million shares of common stock issued as of December 31, 2012. Fully diluted weighted average shares outstanding were 138.0 million for 2012.
