Highlights for the Quarter

Offshore Marine Services – Operating income was $16.1 million on operating revenues of $109.8 million compared with operating income of $7.6 million on operating revenues of $93.3 million in the preceding quarter. Fourth quarter results included $1.4 million in gains on asset dispositions compared with $5.2 million in gains in the preceding quarter. In the fourth quarter, the total number of days available for charter decreased by 56 days, or 0.5%; overall utilization increased from 72.4% to 79.7%; and overall average day rates increased by 7.7% from $11,318 per day to $12,187 per day.

In the U.S. Gulf of Mexico, operating income before gains on asset dispositions was $8.4 million higher in the fourth quarter. Firmer market conditions contributed to a $13.3 million increase in time charter revenues, which was partially offset by higher operating expenses as activity levels increased. Utilization was 70.3% compared with 53.5% in the preceding quarter and average day rates increased from $10,631 per day to $12,523 per day. As of December 31, 2011, the Company had four vessels cold-stacked in the U.S. Gulf of Mexico compared with seven as of September 30, 2011.

In international regions, operating income before gains on asset dispositions was $3.9 million higher in the fourth quarter. Time charter revenues were $2.2 million higher primarily due to an increase in average day rates from $11,612 per day to $11,999 per day. Utilization was 86.2% compared with 85.2% in the preceding quarter. Operating expenses were $2.2 million lower primarily due to reduced drydocking and mobilization expenditures.

Administrative and general expenses were $3.0 million higher in the fourth quarter primarily due to legal fees associated with the fourth quarter acquisition of a controlling interest in a European operator of wind farm utility vessels and higher wage and benefit costs.

Equity in earnings was lower in the fourth quarter primarily due to an $8.4 million gain, net of tax, recognized in the preceding quarter upon Offshore Marine Services’ Mexican joint venture issuing an additional equity interest to an unrelated third party.

Aviation Services – Operating income was $1.5 million on operating revenues of $61.7 million compared with operating income of $15.1 million on operating revenues of $71.8 million in the preceding quarter. Fourth quarter results included $1.9 million in gains on asset dispositions compared with $4.9 million in gains in the preceding quarter.

Operating revenues were $10.1 million lower in the fourth quarter primarily due to the end of seasonal activities in Alaska and a reduction in the number of helicopters operating under contract-leases. Operating expenses were $4.6 million lower in the fourth quarter primarily due to the end of seasonal activities, performance credits received under various vendor arrangements and Aviation Services’ exit from a vendor maintenance agreement. Administrative and general expenses were $5.0 million higher in the fourth quarter primarily due to severance costs associated with a change in executive management.

Inland River Services - Operating income was $12.3 million on operating revenues of $51.9 million compared with operating income of $9.3 million on operating revenues of $47.9 million in the preceding quarter. Operating results improved primarily due to seasonal harvest activity and strong northbound demand for fertilizer shipments for the pooled hopper barge fleet.

Marine Transportation Services – Operating income was $3.7 million on operating revenues of $26.7 million compared with operating income of $1.7 million on operating revenues of $24.8 million in the preceding quarter. Fourth quarter results included $1.1 million in gains on asset dispositions following the sale of the Seabulk America. Operating results for Marine Transportation Services’ U.S.-flag product tanker fleet were higher primarily due to lower operating expenses and less off-hire time associated with one vessel undergoing a special survey in the preceding quarter and lower insurance deductibles. Operating results for its foreign flag Roll-on/Roll-off vessels were lower primarily due to the drydocking of one vessel, charter-in expenses to cover that vessel’s out-of-service time and higher legal fees.

Environmental Services – Operating income was $18.6 million on operating revenues of $59.7 million compared with operating income of $1.0 million on operating revenues of $40.4 million in the preceding quarter. The increase in operating income was primarily due to final settlements with a customer and certain subcontractors in respect of oil spill response services related to the Deepwater Horizon sinking in April 2010.

Commodity Trading and Logistics – Segment profit was $1.4 million on operating revenues of $237.2 million compared with a segment loss of $7.1 million on operating revenues of $279.2 million in the preceding quarter. Operating results improved primarily due to a reduction of volatility in commodity prices and better results from the Company’s alcohol manufacturing joint venture.

Other – Other, primarily Harbor and Offshore Towing Services, reported operating income of $1.7 million on operating revenues of $17.7 million compared with operating income of $2.7 million on operating revenues of $16.7 million in the preceding quarter. The reduction in operating income was primarily due to an increase in charter-in expenses at the Company’s terminal operation in St. Eustatius.

Equity in losses in the fourth quarter were primarily due to losses in one of the Company’s industrial air services joint ventures in Asia.

Corporate and Eliminations – Administrative and general expenses were $10.5 million compared with $6.2 million in the preceding quarter. The increase was primarily due to management bonus accruals and professional fees.

Stock Repurchases – During the fourth quarter, the Company purchased 843,400 shares of its common stock at an average price of $84.48 per share. As of December 31, 2011, 20,933,116 shares of SEACOR’s common stock remained outstanding.

Capital Commitments – The Company’s unfunded capital commitments as of December 31, 2011 consisted primarily of offshore support vessels, helicopters, inland river tank barges, harbor tugs, an interest in a river grain terminal, an interest in a dry-bulk articulated tug-barge and other property and equipment. These commitments totaled $312.5 million, of which $199.3 million is payable during 2012 with the balance payable through 2014. Of the total unfunded capital commitments, $43.6 million may be terminated without further liability other than the payment of liquidated damages of $1.4 million. Subsequent to December 31, 2011, the Company committed to purchase additional equipment for $49.2 million. As of December 31, 2011, the Company held balances of cash, cash equivalents, restricted cash, marketable securities, construction reserve funds and title XI reserve funds totaling $815.8 million.
