Macquarie Infrastructure Company (NYSE: MIC) announced that its management company, Macquarie Infrastructure Management (USA) Inc. (“MIMUSA”), will be paid a performance fee of $43.8 million for the fourth quarter of 2012. Under the publicly filed Management Services Agreement (“MSA”) between MIC and MIMUSA, the management company is entitled to a performance fee equal to 20% of the value of MIC’s total return in excess of the MSCI US Utility Index benchmark provided that the total return is positive and in excess of any prior underperformance. Consistent with the MSA, the performance fee for the quarter reflects an average closing value of the MIC accumulation index for the last 15 trading days of the year that was 9.9% above the average closing of the accumulation index for the 15 trading days ended September 28. Measured the same way, the benchmark index declined 1.3% over the period. The closing price for MIC’s shares on the New York Stock Exchange rose 9.8% during the quarter. MIMUSA is expected to reinvest the performance fee in additional shares of MIC in March of this year. In accordance with the MSA, the price at which those additional shares are issued will be determined by the 15-day volume weighted average price of the shares from February 26 through March 18. MIC is scheduled to release its full year 2012 results after the close of the equity markets in New York on Wednesday, February 20, 2013 and host its earnings call on February 21 at 8:00 am Eastern Time.
