Thank you, Andrew. For the fourth quarter, we generated $99 million in revenues and non-GAAP net income of $2.1 million or $0.11 per diluted common share. These results exclude the goodwill impairment charge. We have a reconciliation to GAAP in our earnings release.
In the fourth quarter, we performed our annual impairment test of goodwill, which resulted in a $120.3 million pretax impairment charge. The charge will have no effect on our cash position or the regulatory capital position of our broker-dealer subsidiaries. A substantial majority of the impaired goodwill was attributable to the 1998 acquisition of our predecessor company by U.S. Bancorp. The impairment represents 100% of the goodwill related to our Capital Markets segment. There was no goodwill impairment associated with the Asset Management segment.
For the fourth quarter, our business mix shifted more to investment banking and Asset Management and away from institutional brokerage compared to the sequential third quarter. We maintained our focus on managing our costs to achieve profitability even at lower revenue levels.
Macro-issues continued to weigh heavily on industry activity levels. Compared to the sequential third quarter however, we raised more equity capital in the U.S. and we completed 2 equity financings in Hong Kong. Public finance par issuance increased 25%, and M&A revenues were solid. Institutional brokerage revenues declined to $32 million, down 17% compared to the sequential third quarter.
Similar to the industry, we experienced slow client activity in the cash equities business. In addition, fixed income revenues were also lower, though results were mixed, including a negative impact on our aircraft business due to American Airlines’ bankruptcy in November. Our strategic trading results were profitable but lower compared to the third quarter due to several factors, including wider spreads on Build America Bond positions and upgrading the credit quality of the tax exempt portion of the portfolio to mitigate risk in the uncertain credit market.
Now I'll comment on expenses. Fourth quarter compensation and benefits expenses were $64 million, down 2% compared to the third quarter of 2011. Our compensation ratio was 64.4%, down from 66.5%, mainly due to lower variable compensation. For the fourth quarter, non-compensation expenses were $34 million on a non-GAAP basis, and in line with our stated goal. For the fourth quarter, we realized a tax benefit of $2.9 million, of which $1.8 million was attributable to the goodwill impairment charge. The remainder of the benefit mainly resulted from the tax exemption on municipal interest.
In the fourth quarter, we repurchased $6 million or 294,000 shares of our common stock at an average price per share of $20.40. For the full year, we acquired $26.5 million or 803,500 shares of our common stock, 510,000 shares of which was related to employee tax obligations on vesting of equity awards. We have $51.4 million remaining on a share repurchase authorization, which expires in September 30, 2012.
