Macquarie Infrastructure Company (NYSE: MIC) announced that it expects a decision in the arbitration involving itself and the co-shareholder of International-Matex Tank Terminals ("IMTT") after February. MIC initiated the arbitration in April of 2011 as a means of resolving differences with its co-shareholder principally over distributions paid from IMTT to MIC.

At the conclusion of the in-person portion of the hearing in January, the arbitration panel set February 15 as the date for closing legal arguments. As MIC had previously requested a written assessment of the factors considered in the final award making, the Company believes it is unlikely the panel will render a decision before the end of February.

MIC remains positive with respect to its ability to succeed on the merits of its case and to increase shareholder dividends as previously indicated.

In a separate comment MIC noted that its aviation related business, Atlantic Aviation, had successfully lowered debt levels and removed restrictions on its ability to make dividend payments to MIC. Atlantic is now expected to dividend about $25.0 million to MIC from the fourth quarter of 2011 until the start of the fourth quarter of 2012.

Under the terms of the Atlantic loan agreement, while the leverage level remains below 6.0 times, the business will dividend 50% of the cash it is generating up to MIC. The leverage level in the business was reduced to below 6.0 times trailing twelve month EBITDA at December 31, 2011.

MIC is scheduled to release its financial results for the full year 2011 following market close on Wednesday, February 22.
