History
Mariner Energy merged with Forest Oil's Gulf of Mexico business in 2006, bought more assets with bank debt that it refinanced with bonds and share sales, and was bought by Apache in November 2010.
1997-2006: A quiet record, then the Forest merger
The record opens in January 1997, when Mariner Energy suspended its duty to file periodic reports with the SEC. After that the record is quiet until 2005, when the company set out on its first big step. In September 2005 it agreed to merge with Forest Energy Resources, Inc., the Gulf of Mexico business that Forest Oil Corporation planned to spin off. Forest shareholders were to receive one Mariner share for each Forest Energy Resources share and end up with about 58% of Mariner, with up to 50,637,010 new Mariner shares registered. Mariner's own stockholders received no payment but had to vote to approve the deal and to lift authorized shares from 90 million to 200 million. No public market existed for Mariner stock then; the last sale the company knew of was at $20.00 in October 2005.
The New York Stock Exchange cleared the shares for listing in February 2006, and the merger closed on March 2, 2006, with Mariner issuing 50,637,010 shares. Mariner also signed a new credit agreement with a $500 million revolving facility, starting with a $400 million borrowing base (the amount banks will lend against its assets), secured on substantially all its assets. In April the borrowing base rose to $430 million, and Mariner sold $300 million of 7 1/2% senior notes due 2013, larger than the $250 million first planned. Net proceeds of about $287.8 million repaid bank debt.
2007-2008: Bonds and a shelf purchase
Mariner kept swapping secured bank debt for unsecured bonds. In April 2007 it amended its credit agreement to allow more bonds, then priced and closed $300 million of 8% senior notes due 2017, upsized by $100 million from the first announcement. About $292.4 million of net proceeds repaid bank borrowings, and the borrowing base stayed at $450 million.
In January 2008 Mariner bought Mariner Gulf of Mexico LLC, formerly Hydro Gulf of Mexico, L.L.C., an indirect StatoilHydro subsidiary, for about $243 million, funded from its credit facility. The business had estimated proved reserves of 52.4 billion cubic feet equivalent (95% developed) and about 53 million cubic feet equivalent a day of net output. The same month the facility was raised to a $1 billion maximum with a $750 million borrowing base, and a separate $40 million letter of credit facility for Forest Oil ended because Mariner had met its drill-to-earn obligations. In June 2008 the borrowing base rose to $850 million, and Mariner settled hurricane insurance claims for Katrina and Rita for about $48.5 million net.
2009: Tighter credit, new equity and Edge
By March 2009 conditions had tightened. Mariner kept the $850 million borrowing base for the time being but agreed to a lower $800 million request at the next review, and interest costs on borrowings rose by 1.0%. In June it chose not to renew extra commercial hurricane insurance, saying it believed its assets were sufficiently insured through OIL Insurance.
In June 2009 Mariner raised money in two ways at once. It issued $300 million of 11.75% senior notes due 2016, netting about $284.8 million, and sold 11.5 million new shares at $14.50, netting about $159.2 million. Around $446.2 million of proceeds went to repay bank debt. The share sale diluted existing holders, and shares on issue ended 2009 at 101,806,825. On December 31, 2009 Mariner completed buying the reorganized subsidiaries of bankrupt Edge Petroleum for $260 million less adjustments, about $214 million net, funded from its bank facility. The assets included about 106 billion cubic feet equivalent of proved reserves, about 80% in South Texas. In December it also received about $46 million from OIL Insurance for Katrina, Rita and Ike.
2010: Sale to Apache
On April 14, 2010 Mariner agreed to be acquired by Apache Corporation. Each share would receive 0.17043 Apache share plus $7.80 in cash by default, or holders could elect all cash at $26.00 or all stock at 0.24347 Apache share, subject to proration. Mariner could owe a $67 million termination fee in certain cases. The proxy statement went out in October, saying Mariner holders would own about 5% of Apache and that the board unanimously recommended a yes vote.
The merger closed on November 10, 2010, and Mariner ceased to exist as a separate company, merging into Apache Deepwater LLC. Holders received about 17.5 million Apache shares and about $800 million in cash in total. Cash electors got $26.00; because stock was oversubscribed, all-stock electors got 0.198113 Apache share plus $4.84. Mariner's stock was delisted from the NYSE on November 12, and its registration was terminated on November 22. As of the latest record, notice had been given to redeem the three note issues, now obligations of Apache Deepwater LLC and Apache MEI Finance, Inc., on December 13 and 14, 2010.
