Commitments and Contingencies	10. Commitments and Contingencies The Company leases certain offices, shop and warehouse facilities, automobiles and equipment. Total lease expense incurred was $2.9 million, $3.7 million and $3.3 million in 2012, 2011 and 2010, respectively. Future annual minimum lease commitments at December 31, 2012 are as follows: 2013—$1.7 million; 2014—$900,000; 2015—$445,000, 2016—$220,000; 2017—$192,000; and thereafter—$1.7 million. In November 2007, the Company entered into a lease agreement in Singapore for approximately 11 acres of vacant land. The lease term is 30 years but with an additional extension of 13 years on certain conditions. The lease term is 30 years and the Company elected to make a lump sum payment for that initial 30-year term. Also, the Company has been granted the right to an additional 13 year extension of the lease as a result of making certain investments in machinery, leasehold improvements and buildings. Deepwater Horizon Incident On April 22, 2010, a deepwater U.S. Gulf of Mexico drilling rig known as the Deepwater Horizon, operated by BP Exploration & Production, Inc. (“BP”), sank after an explosion and fire that began on April 20, 2010. The Company is a party to an ongoing contract with an affiliate of BP to supply wellhead systems in connection with BP’s U.S. Gulf of Mexico operations, and the Company’s wellhead and certain of its other equipment were in use on the Deepwater Horizon at the time of the incident. A moratorium was placed on offshore deepwater drilling on May 28, 2010 in the U.S. Gulf of Mexico and was lifted on October 12, 2010. The Company was named, along with other unaffiliated defendants, in both class action and other lawsuits arising from the Deepwater Horizon incident. The actions filed against the Company were consolidated, along with hundreds of other lawsuits not directly naming the Company, in the multi-district proceeding In Re: Oil Spill by the Oil Rig “Deepwater Horizon” in the Gulf of Mexico, on April 20, 2010 (“MDL Proceeding”). The lawsuits generally allege, among other things, violation of state and federal environmental and other laws and regulations, negligence, gross negligence, strict liability, personal injury and/or property damages and generally seek awards of unspecified economic, compensatory and punitive damages and/or declaratory relief. On January 20, 2012, the judge presiding over the MDL Proceeding, another related proceeding filed by affiliates of Transocean Ltd under the Limitation of Liability Act, and the U.S. government’s action under the Oil Pollution Act, issued an order that granted the Company’s Motion for Summary Judgment and dismissed all claims asserted against the Company in those proceedings with prejudice. On April 9, 2012, the judge issued an order granting a final judgment in favor of the Company with respect to the court’s prior order that granted the Company’s Motion for Summary Judgment. Additional lawsuits may be filed and additional investigations may be launched in the future. An adverse outcome with respect to any of these lawsuits or investigations, or any lawsuits or investigations that may arise in the future, could have a material adverse effect on the Company’s results of operations. The Company intends to continue to vigorously defend any litigation, fine and/or penalty relating to the Deepwater Horizon incident. The Company does not believe this litigation will have a material impact and accordingly, no liability has been accrued in conjunction with these matters. At the time of the Deepwater Horizon incident, the Company had a general liability insurance program with an aggregate coverage limit of $100 million for claims with respect to property damage, injury or death and pollution. The coverage was increased to $200 million in October 2010. The insurance policies may not cover all potential claims and expenses relating to the Deepwater Horizon incident. In addition, the Company’s policies may not cover fines, penalties or costs and expenses related to government-mandated clean up of pollution. The Company has received a “reservation of rights” letter from its insurer. This letter details the insurer’s obligation under the current policy and the insurer’s interpretation of key provisions within the policy relating to any claims arising out of the Deepwater Horizon incident. The incident may also lead to further tightening of the availability of insurance coverage. If liability limits are increased or the insurance market becomes more restricted, the risks and costs of conducting offshore exploration and development activities may increase, which could materially impact the Company’s results of operations. Brazilian Tax Issue From 2002 to 2007, the Company’s Brazilian subsidiary imported goods through the State of Espirito Santo in Brazil and subsequently transferred them to its facility in the State of Rio de Janeiro. During that period, the Company’s Brazilian subsidiary paid taxes to the State of Espirito Santo on its imports. Upon the final sale of these goods, the Company’s Brazilian subsidiary collected taxes from customers and remitted them to the State of Rio de Janeiro net of the taxes paid on importation of those goods to the State of Espirito Santo in accordance with the Company’s understanding of Brazilian tax laws. In August 2007, the State of Rio de Janeiro served the Company’s Brazilian subsidiary with assessments to collect a state tax on the importation of goods through the State of Espirito Santo from 2002 to 2007 claiming that these taxes were due and payable to it under applicable law. The Company settled these assessments with payments to the State of Rio de Janeiro of $12.2 million in March 2010 and $3.9 million in December 2010. Approximately $7.8 million of these settlement payments were attributable to penalties, interest and amounts that had expired under the statute of limitations so that amount was recorded as an expense. The remainder of the settlement payments generated credits (recorded as a prepaid tax) that can be used to offset future state taxes on sales to customers in the State of Rio de Janeiro once certified by the tax authorities under a process that is currently ongoing. In December 2010 and January 2011, the Company’s Brazilian subsidiary was served with additional assessments totaling approximately $13.0 million from the State of Rio de Janeiro to cancel the credits associated with the tax payments to the State of Espirito Santo (“Santo Credits”) on the importation of goods from July 2005 to October 2007. The Santo Credits are not related to the credits described in the immediately preceeding paragraph. The Company has objected to this assessment as it would represent double taxation on the importation of the same goods and that the Company is entitled to the credits under applicable Brazilian law. The Company believes that these credits are valid and that success in the matter is probable. Based upon this analysis the Company has not accrued any liability in conjunction with this matter. Since 2007, the Company’s Brazilian subsidiary has paid taxes on the importation of goods directly to the State of Rio de Janeiro and the Company does not expect any similar issues to exist for periods subsequent to 2007. ATP Bankruptcy The Company has entered into several contracts with ATP Oil & Gas Corporation (“ATP”). In August 2012, ATP filed for bankruptcy in the U.S Bankruptcy Court in the Southern District of Texas. At December 31, 2012, the Company had $1.4 million of receivables owed by ATP or its subsidiaries and $4.3 million in customer prepayments from ATP. The Company has not provided for any losses due to the ATP bankruptcy filings as of December 31, 2012. General The Company operates its business and markets its products and services in most of the significant oil and gas producing areas in the world and is, therefore, subject to the risks customarily attendant to international operations and dependency on the condition of the oil and gas industry. Additionally, products of the Company are used in potentially hazardous drilling, completion, and production applications that can cause personal injury, product liability, and environmental claims. Although exposure to such risk has not resulted in any significant problems in the past, there can be no assurance that ongoing and future developments will not adversely impact the Company. The Company is also involved in a number of legal actions arising in the ordinary course of business. Although no assurance can be given with respect to the ultimate outcome of such legal action, in the opinion of management, the ultimate liability with respect thereto will not have a material adverse effect on the Company’s operations, comprehensive income, financial position or cash flows.
