ITEM 1. BUSINESS
GENERAL
Noble Drilling Corporation is a leading provider of diversified services for the oil and gas industry worldwide. The Company's activities include offshore and land drilling services, turnkey drilling services and engineering and production management services. The Company's drilling fleet is broadly diversified, allowing it to work in a variety of operating conditions.
Noble Drilling Corporation ("Noble Drilling") was organized as a Delaware corporation in 1939. Noble Drilling and its predecessors have been engaged in the contract drilling of oil and gas wells for others domestically since 1921 and internationally during various periods since 1939. As used herein, unless otherwise required by the context, the term "Noble Drilling" refers to Noble Drilling Corporation and the term "Company" refers to Noble Drilling and its consolidated subsidiaries.
BUSINESS STRATEGY
The Company's business strategy has been to expand its international and deepwater offshore capabilities through acquisitions, redeployments and rig modifications, and to position itself in geologically promising areas. The Company has actively pursued its strategy in recent years. During 1995, the Company increased its international presence by transferring two independent leg jackup rigs and one mat slot rig from the U.S. Gulf of Mexico to the West Coast of Africa. The Company also transferred one of its two rigs located in Mexico to Qatar during 1995. The domestic land drilling operations of the Company have become less significant as the Company has emphasized its offshore and international operations.
The offshore contract drilling industry has, in recent years, experienced a series of asset sales and consolidations among drilling contractors, and the Company expects this trend to continue as drilling contractors position themselves strategically in the market. The Company, from time to time, has discussions with third parties regarding asset acquisitions or business combinations and intends to continue to consider business opportunities that it believes promote this business strategy.
The Company's revenues are balanced between international and domestic sources. The following table sets forth, for the periods indicated, the percentages of international and domestic operating revenues:
ACQUISITION OF ASSETS
In October 1995, the Company purchased two jackup drilling units and related equipment for a total of $10,100,000 in cash. The Azteca, which the Company plans to rename the Gene Rosser after the pending purchase of that rig is completed, and the Maya are both Levingston 111, 300-foot, independent leg jackup rigs. The Azteca is currently located in a shipyard undergoing refurbishment and conversion to a cantilever rig. The Maya is scheduled to commence such refurbishment and cantilever modification in the second quarter of 1996.
RECENT DEVELOPMENTS
LETTER OF INTENT TO PURCHASE ASSETS OF NEDDRILL
On March 13, 1996, the Company entered into a letter of intent with Royal Nedlloyd N.V. and its wholly owned subsidiary, Neddrill Holding B.V. and its subsidiaries (collectively, "Neddrill"), to acquire the assets, including $25,000,000 in net working capital, and the personnel used by Neddrill in its offshore contract drilling, accommodation and other oil and gas exploration and production related service businesses. The purchase price would be $300,000,000 in cash plus 5,000,000 shares of Noble Drilling common stock. The Company currently plans to access the public securities markets to finance the cash portion of the purchase price.
Neddrill's operations are managed from its headquarters in Rotterdam, The Netherlands. Its fleet includes two dynamically positioned drillships, one of which is currently operating in Angola, the second in Brazil; one second generation semisubmersible rig operating in the North Sea, and six harsh environment jackup drilling rigs (five operating in the North Sea and one in Argentina). Neddrill operates a third dynamically positioned drillship in which it owns a partial interest through a joint venture arrangement. In addition, the Company would acquire rights, under a bareboat charter, to a seventh harsh environment jackup rig operating as a hotel accommodation unit in the North Sea. All the above units are currently under contract, with commitments extending through 1997 to 2001, depending on the unit.
Negotiations have reached the stage that justifies the expectation that an agreement on the proposed acquisition can be reached. Notices have been given by Nedlloyd to the Social and Economic Council in The Netherlands and the Central Works Council of Nedlloyd in accordance with applicable laws, regulations and practices in The Netherlands.
Consummation of the acquisition is subject to customary due diligence, execution and delivery of an agreement of sale and purchase, financing being obtained by the Company, and satisfaction of customary closing conditions expected to be contained in the agreement of sale and purchase.
ASSET RATIONALIZATION PROGRAM
Consistent with the Company's plan to focus on deepwater drilling, the Company has sold one of its posted barge units (Gus Androes) and has contracted to sell a second posted barge unit (Gene Rosser). The closing of the sale of this second barge unit is scheduled to occur on or before March 29, 1996.
The Company plans to use the net proceeds from these sales, together with working capital if needed, to enhance the deepwater capability of its fleet. On February 26, 1996, the Company purchased the Odin Explorer, to be renamed the Gus Androes, a 300-foot independent leg cantilevered jackup rig located offshore Sharjah, U.A.E. This rig has been stacked and will require substantial refurbishment prior to being returned to service. In addition, the Company received notification on March 6, 1996 of acceptance of its offer to purchase the rig Dana, a 250-foot independent leg cantilevered jackup rig, which is currently under a management contract in Qatar.
LINN RICHARDSON DAMAGE
On December 15, 1995, the Linn Richardson, a 250-foot mat slot rig, lost overboard approximately 200 feet of leg while under tow to perform a contract offshore Senegal, Africa. On the following day, the rig lost overboard approximately 240 feet of a second leg which also caused damage to equipment and facilities on the deck of the rig. Pursuant to a preliminary assessment plan developed jointly by the Company and its insurance underwriters, the third leg of the rig has been removed and the rig has been towed to the U.S. Gulf of Mexico where a complete evaluation will take place. A charge of $1,778,000 related to the cost of mobilizing the rig to Senegal was accrued in the fourth quarter of 1995. This amount represents management's best estimate of the total loss. Management does not believe this incident will have any other material adverse effect on its financial condition or results of operations.
RIG UTILIZATION
The following table sets forth the average rig utilization rates for the Company's rig fleet for the periods indicated:
- ------------------------
(1) Information reflects the policy of the Company to report utilization rates based on the number of actively marketed rigs owned in the fleet. During the periods presented, the Company purchased and sold certain drilling rigs. Utilization rates for the periods prior to sales and purchases of such rigs have not been adjusted.
DRILLING CONTRACTS
The Company's drilling contracts are obtained through competitive bidding or as a result of negotiations with customers. Contracts for land rigs are normally for a single well, while contracts involving offshore drilling frequently are
for a period of time and may involve several wells. The Company's offshore drilling is normally contracted on a dayrate basis, except for its turnkey operations (see "Business - Turnkey Drilling and Engineering Services"). Land drilling is performed on either a dayrate or a footage basis. The risk of loss to the Company on wells drilled on a turnkey or footage basis is significantly higher than on wells drilled on a dayrate basis.
OFFSHORE DRILLING OPERATIONS
The Company's offshore drilling operations are conducted worldwide. Principal regions of operations currently include the Gulf of Mexico, West Africa, Venezuela and, to a lesser extent, India, Mexico and Qatar. The offshore fleet consisted of 46 rigs, comprising 35 jackup drilling rigs, eight submersible rigs and three posted barges at February 26, 1996. For information regarding recent changes in the composition of the Company's fleet, see "Business - Recent Developments."
In 1995, one of the Company's customers, Lagoven, a subsidiary of the government-owned oil company of Venezuela, accounted for approximately 11 percent of the Company's total operating revenues.
INTERNATIONAL CONTRACT DRILLING
The Company's international offshore contract drilling operations are conducted in Nigeria, Venezuela, Qatar, Zaire, Mexico, and India. At February 26, 1996, the Company's international offshore contract drilling fleet consisted of 19 rigs, of which 15 were working under contract, one was available for bidding, one was under contract for sale, one was in the shipyard, and one was under evaluation following damages sustained during transportation.
In 1995, approximately 55 percent of the Company's international offshore contract drilling revenues was derived from contracts with major oil and gas companies, 37 percent from government-owned companies and the balance from contracts with independent operators.
The Company has seven jackup rigs and two posted barges located along the West Coast of Africa. Six of the jackup rigs are under long-term contracts extending through dates ranging from December 1996 to June 1998, with major oil companies. The seventh jackup rig is available for work. The two posted barges are under contract through June 1996. A third posted barge has been transported recently from Nigeria to Singapore in connection with its impending sale.
The Company has four jackup rigs located in Venezuela. Three of these rigs are under long-term contracts extending through dates ranging from July 1997 to June 2000. The fourth is working under a well-to-well contract.
The Company also has a jackup rig working in Qatar under a long-term contract that expires in 1998, a jackup rig working in India under a long-term bareboat charter agreement that expires in September 1996 and a jackup rig working in Mexico under a long-term contract that expires in November 1996. The recently purchased Odin Explorer is located in Sharjah, U.A.E.
DOMESTIC CONTRACT DRILLING
The Company's domestic offshore contract drilling fleet consisted of 27 rigs at February 26, 1996, of which 18 were working under contract, two were being refurbished, and seven were being held in various stages of readiness to enter the marketplace. The Company continually evaluates the economics of re-entering the market with these rigs and expects to do so when conditions warrant.
Two of the Company's independent slot rigs, the Eddie Paul and the John Sandifer, completed refurbishment projects in 1995. The Eddie Paul was converted to an Extended Reach Cantilever ("ERC") rig to enable this unit to drill over larger platforms. This rig's legs were extended from 467 feet to 500 feet to increase the water depth capacity to approximately 390 feet. A top drive drilling system and cascading mud system were also installed on this rig. The modifications make the Eddie Paul the largest rig in the Gulf of Mexico in terms of cantilever reach and one of the largest in terms of water depth. The John Sandifer was converted to a cantilever rig with a top drive system and cascading mud system to make the rig more versatile. The total cost of these two projects approximated $35,134,000 over 1994 and 1995. Both rigs were contracted for work prior to completion of shipyard work and have been under contract since departure from the shipyard.
In 1995, approximately 55 percent of the Company's domestic offshore contract drilling revenues was derived from contracts with major oil and gas companies and the remaining 45 percent was derived from contracts with independent operators.
LABOR CONTRACTS
The Company's offshore operations also include labor contracts for drilling and workover activities covering 13 rigs operating in the U.K. North Sea and one offshore rig operating in Qatar. These rigs are not owned or leased by the Company. Under its labor contracts, the Company provides the personnel necessary to manage and perform the drilling operations from drilling platforms owned by the operator. The contracts are generally renewable no more frequently than on an annual basis. After drilling operations are completed, workover operations usually become an important element of each platform's activity. Thus, drilling contractor crews usually remain on the platform until a field is depleted by production.
The Company was awarded a contract in 1994 by Hibernia Management and Development Company Ltd. for offshore production drilling and related services. The contract calls for the Company to commission, operate and maintain two state-of-the-art platform rigs to be installed on the concrete gravity-based structure that will be used to develop the Hibernia field off the coast of Newfoundland. The Company established an office in St. Johns, Newfoundland in late 1994. A team of six experienced personnel are employed in St. Johns and are presently participating in the preparation of operating, equipment maintenance and procedures manuals, and the procurement of equipment. Commissioning of the drilling and related equipment will commence in May 1996 through November 1996. The gravity-based structure is scheduled for tow out to location in May 1997, with commencement of the first well scheduled to occur in early September 1997. The Company has a five-year contract with Hibernia with an option for a five-year extension. It is anticipated that the Company will have approximately 120 employees assigned to this project at its peak in 1997.
LAND DRILLING OPERATIONS
The Company's land drilling operations are conducted in Canada, Texas and Louisiana. At February 26, 1996, 19 of the Company's 46 land rigs were available for active bidding by the Company. Of these 19 rigs, 10 were located in the United States and nine were located in Canada. Thirteen of the 19 actively-marketed rigs were operating under contract and six were available for bidding at that date. Twenty-seven rigs were stacked and not being actively marketed. The remaining net book value of these stacked rigs is not material. The Company's domestic land drilling operations have become less significant as the Company has emphasized its offshore and international operations.
TURNKEY DRILLING AND ENGINEERING SERVICES
Through its wholly owned subsidiary, Triton Engineering Services Company ("Triton"), the Company provides turnkey drilling, drilling project management, drilling and completion planning and design, specialized drilling tools and services, and contract engineering and consulting manpower. Turnkey drilling, Triton's major service, involves the coordination of all equipment, materials, services and management to drill a well to a specified depth, for a fixed price. Under turnkey drilling contracts, Triton bears the financial risk of delays in the completion of the well. In providing its services, Triton can use drilling rigs owned either by the Company or by a third party, depending on availability. The drilling of a turnkey well is generally completed within 30 to 50 days. Twenty-seven wells were completed by Triton in 1995 compared to 35 wells for 1994. Seven of the 35 wells were completed prior to the Company's acquisition of Triton in April 1994. Revenues from turnkey drilling services represented 22 percent and 16 percent of consolidated operating revenues in 1995 and 1994, respectively. The revenue percentage for 1994 consists of Triton's revenues from the time of the acquisition in April 1994 through year end 1994.
The Company provides engineering services relating primarily to the design of drilling equipment for offshore development and production services and to the recertification of oilfield equipment. The Company works, on a contract basis, with operators and prime construction contractors of drilling and production platforms in the design of drilling equipment configurations aimed at optimizing the operational efficiency of developmental drilling by maximizing platform space utilization and load capability.
Through its operations in Venezuela, the Company provides engineering services in the form of an alliance program with Lagoven. The Company utilizes its own drilling rigs and employs Triton personnel for the engineering and operating expertise.
COMPETITION AND RISKS
The contract drilling industry is a highly competitive and cyclical business characterized by high capital and maintenance costs. Although conditions in recent years in the oil and gas industry have precipitated consolidation of industry participants, there remains an oversupply of drilling equipment. As a consequence, there has been intense competition for available drilling contracts resulting in much equipment being idle for long periods of time and generally unfavorable terms and prices for contract drilling. Certain competitors of the Company may have access to greater financial resources than the Company.
Competition in contract drilling involves numerous factors, including price, the experience of the work force, rig availability and suitability, efficiency, condition of equipment, operating integrity, reputation, industry standing and customer relations. Price is the major consideration in most markets, especially with respect to domestic drilling. The Company believes it competes favorably with respect to all these factors. The acquisition of Triton has enabled the Company to compete more effectively in the turnkey drilling market. Competition is primarily on a regional basis and may vary significantly by region at a particular time. Demand for land and offshore drilling equipment is also dependent on the exploration and development programs of oil and gas producers, which are in turn influenced by the financial condition of such producers, by general economic conditions and prices of oil and gas, and, from time to time, by political considerations and policies.
It is impracticable to estimate the number of competitors of the Company. Many independent drilling contractors in recent years have sought protection from creditors under bankruptcy laws or have combined with other companies as a result of the depressed conditions in the contract drilling industry. Although this has reduced the total number of competitors, management of the Company believes that competition for drilling contracts will continue to be intense for the foreseeable future.
The Company follows a policy of keeping its equipment well maintained and technologically competitive. However, its equipment could be made obsolete by the development of new techniques and equipment. In addition, industry-wide shortages of supplies, services, skilled personnel and equipment necessary to conduct the Company's business, such as drill pipe, have occurred from time to time in the past, and such shortages could occur again.
The Company's operations are subject to the many hazards inherent in the drilling business, including blowouts, cratering, fires and collisions or groundings of offshore equipment, which could cause substantial damage to the environment. In addition, the Company's operations are subject to damage or loss from adverse weather and seas. These hazards could cause personal injury and loss of life, suspend drilling operations or seriously damage or destroy the property and equipment involved and, in addition to environmental damage, could cause substantial damage to producing formations and surrounding areas. Although the Company maintains insurance against many of these hazards, such insurance is subject to substantial deductibles and provides for premium adjustments based on claims. It also excludes certain matters from coverage, such as loss of earnings on certain rigs. Also, while the Company generally obtains indemnification from its customers for environmental damage with respect to offshore drilling, such indemnification is generally only in excess of a specified amount, which typically ranges from $100,000 to $250,000.
In the case of the turnkey drilling operations, the Company maintains insurance against pollution and environmental damage in amounts ranging from $5,000,000 to $50,000,000 depending on location, subject to self-insured retentions of $25,000 to $1,000,000. Under turnkey drilling contracts, Triton generally assumes the risk of pollution and environmental damage, but on occasion receives indemnification from the customer for environmental and pollution liabilities in excess of Triton's pollution insurance coverage. Further, Triton is not insured against certain drilling risks that could result in delays or nonperformance of a turnkey drilling contract, although it generally maintains insurance against delays related to loss of well control. Triton typically obtains contractual indemnification from the drilling contractors that provide the rigs for Triton's turnkey drilling operations for pollution arising from certain acts of such contractors.
The Company's international operations are also subject to certain political, economic and other uncertainties including, among others, risks of war and civil disturbances, expropriation, nationalization, renegotiation or modification of existing contracts, taxation policies, foreign exchange restrictions, international monetary fluctuations and other hazards arising out of foreign governmental sovereignty over certain areas in which the Company conducts operations. The Company has insurance covering expropriation and other political risks to the extent available to the Company at rates it considers prudent to pay.
GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS
Many aspects of the Company's operations are affected by domestic and foreign political developments and are subject to numerous governmental regulations that may relate directly or indirectly to the contract drilling industry. The regulations applicable to the Company's operations include certain provisions that regulate the discharge of materials into the environment or require remediation of contamination, under certain circumstances. Usually these environmental laws and regulations impose "strict liability," rendering a person liable without regard to negligence or fault on the part of such person. Such environmental laws and regulations may expose the Company to liability for the conduct of, or conditions caused by, others, or for acts of the Company that were in compliance with all applicable laws at the time such acts were performed.
The U.S. Oil Pollution Act of 1990 ("OPA '90") and the regulations promulgated pursuant thereto impose certain additional operational requirements on the Company's domestic offshore rigs and govern liability for leaks, spills and blowouts. Regulations under OPA '90 may increase the level of financial assurance required of owners and operators of rigs in the waters of the United States. The Company has monitored these regulations and does not believe that they are likely to have a material adverse effect on the Company's financial condition or results of operations.
The Company has made and will continue to make expenditures to comply with environmental requirements. The Company does not believe that it has to date expended material amounts in connection with such activities or that compliance with such requirements will have a material adverse effect upon its capital expenditures, results of operations or competitive position. Although such requirements do have a substantial impact upon the energy and energy services industries, generally they do not appear to affect the Company any differently or to any greater or lesser extent than other companies in the energy services industry.
The Company believes that insurance in place and indemnities the Company generally seeks to include in its drilling contracts provide the Company with an appropriate degree of protection from liability resulting from current governmental regulation that might have a material adverse effect on the Company, including environmental regulation. However, notwithstanding the indemnity coverage provided to, and insurance coverage carried by, the Company, the occurrence of a significant event not fully indemnified against or insured for or the failure of a customer to meet its indemnification obligations could materially and adversely affect the Company's operations and financial condition.
The modification of existing laws or regulations or the adoption of new laws or regulations curtailing exploratory or development drilling for oil and gas for economic, environmental or other reasons could materially and adversely affect the Company's operations by limiting drilling opportunities.
EMPLOYEES
At December 31, 1995, the Company had approximately 2,977 employees, of whom 56 percent were engaged in international operations and 44 percent were engaged in domestic operations. Over many years, the Company has developed and maintained a well-trained and experienced workforce.
The Company is not a party to any collective bargaining agreements that are material to the Company. The Company considers its employee relations to be satisfactory.
Although there continues to be an oversupply of drilling equipment industry-wide, shortages of supplies and equipment, as well as qualified personnel for rig crews, have occurred from time to time in the past. A substantial increase in demand for oilfield services could make it more difficult to retain and recruit qualified rig crew members without significant increases in compensation.

ITEM 2. PROPERTIES
DRILLING RIG FLEET
OFFSHORE DRILLING RIGS
The Company's offshore drilling rig fleet consisted of 35 jackup rigs, eight submersible rigs and three posted barges at February 26, 1996. Each type of rig is described further below. There are several factors that determine the type of rig most suitable for a particular job, the more significant of which include the water depth and bottom conditions at the proposed drilling location, whether the drilling is being done over a platform or other structure, and the intended well depth.
Seventeen of the Company's 46 offshore rigs have a top drive unit, and the Company has three additional top drive units which have not been installed on rigs. A top drive unit is a technologically-advanced drilling tool used in many drilling applications both offshore and on land. Twenty-eight of the Company's 46 offshore rigs are equipped with cascading solids control systems. A cascading solids control system is a highly efficient method for controlling the solids in drilling mud, the use of which enhances removal of well bore cuttings and results in better bit performance and reduced mud conditioning costs to the operator. In addition, ten of the Company's 46 offshore rigs are equipped with zero discharge capability.
JACKUP RIGS. The Company had 35 jackup rigs in the fleet at February 26, 1996. Jackup rigs are mobile self-elevating drilling platforms equipped with legs which can be lowered to the ocean floor until a foundation is established to support the drilling platform. The rig hull includes the drilling rig, jacking system, crew quarters, loading and unloading facilities, storage areas for bulk and liquid materials, helicopter landing deck and other related equipment. The rig legs may operate independently or have a mat attached to the bottom of them in order to provide a more stable foundation in soft bottom areas. Twenty-two of the Company's jackup rigs are independent leg rigs and 13 are mat supported rigs. Moving a rig to the drill site involves jacking up its legs until the hull is floating on the surface of the water. The hull is then towed to the drill site by tugs and the legs are jacked down to the ocean floor. The jacking operation continues until the hull is raised out of the water and drilling operations are conducted with the hull in its raised position. A cantilevered jackup has a feature that permits the drilling platform to be extended out from the hull, allowing it to perform drilling or workover operations over pre-existing platforms or structures. Slot type jackup rigs are configured for the drilling operations to take place through a slot in the hull. The Company's jackup rigs are capable of drilling to a maximum depth of 25,000 feet in water depths ranging between 8 and 390 feet, depending on the jackup rig.
SUBMERSIBLE RIGS. The Company had eight submersibles in the fleet at February 26, 1996. Submersible rigs are mobile drilling platforms which are towed to the drill site and submerged to drilling position by flooding the lower hull until it rests on the sea floor, with the upper deck above the water surface. The Company's submersible rigs are capable of drilling to a maximum depth of 30,000 feet in water depths ranging between 12 and 100 feet, depending on the submersible rig.
POSTED BARGES. The Company had three posted barges in the fleet at February 26, 1996. Use of the posted barge is not part of the Company's long-term strategic objectives. See "Business - Business Strategy" and "Business - - Recent Developments."
The following table sets forth certain information concerning the Company's offshore drilling rig fleet at February 26, 1996. The table does not include 14 offshore rigs owned by operators for which the Company had labor contracts as of February 26, 1996. Unless otherwise indicated, the Company owns and operates the rigs included in the table.

(7) Owned by NN-1 Limited Partnership, of which Noble Drilling is the general partner and in which it has a majority interest. The rig is mortgaged under a first preferred ship mortgage in favor of the United States government to secure repayment of the U.S. Government Guaranteed Ship Financing Sinking Fund Bonds issued in 1978 by the predecessor of the partnership in connection with the construction and purchase of the rig.
(8) Reactivation project completed in January 1996.
(9) Purchased February 26, 1996.
LAND DRILLING RIGS
The Company's land drilling fleet consists of 46 rigs, of which 19 are being or can be actively bid by the Company. See "Business - Land Drilling Operations." Intended well depth, drill site conditions and drilling applications are the principal factors in determining the size and type of land rig to be used for a particular job. Of the 19 actively bid rigs in the fleet, seven are mechanical and 12 are electric. Mechanical land rigs transmit the engine power to the rig equipment through converters, compounds, chains and V-belts. Electric land rigs transmit the engine power to rig equipment through generators and electric cables to electric motors on the rig components.
The following table sets forth certain information concerning the Company's 19 actively bid land drilling rigs at February 26, 1996. The table does not include 27 mothballed or stacked rigs.

- -------------------
(1) The Selected Financial Data presents the restatement of the Company's historical financial statements for 1994 and prior periods to reflect the 1994 merger of Chiles Offshore Corporation ("Chiles") into Noble Offshore Corporation ("NOC"), a wholly-owned subsidiary of the Company, which was accounted for as a pooling of interests. The Selected Financial Data also includes the acquisition of Triton in April 1994 and the October 1993 acquisition of nine offshore rigs and associated assets from The Western Company of North America, both of which were accounted for under the purchase method.
(2) Consists of operating costs and expenses other than depreciation and amortization, selling, general and administrative, minority interest, restructuring charges and write-down of assets charges.
(3) Effective January 1, 1995, the Company revised its estimates of salvage values and remaining depreciable lives of certain rigs. The effect of this change was a reduction to depreciation and amortization of $6,160,000, or $0.07 per common share for the year ended December 31, 1995.
(4) Consists of provisions resulting from write-downs of certain assets, facility consolidation costs and, to a lesser extent, severance costs.
(5) Consists of a gain on extinguishment of debt in 1993 and a gain on an insurance settlement in 1991.
(6) Net (loss) income applicable to common shares per share before extraordinary item was $0.20 and $(0.92) for the years ended December 31, 1993 and 1991, respectively. Loss applicable to common shares per share from discontinued operations was $(0.07) and $(0.04) for the years ended December 31, 1992 and 1991, respectively.
(7) Chiles reclassified $50,500,000 of its outstanding indebtedness from long-term to current liabilities in 1991.
(footnotes continued on following page)
This reclassification was made because as of December 31, 1991, Chiles anticipated not being able to remain in compliance, and subsequently was not able to remain in compliance, with all of the terms of its debt agreements.
(8) Consists of short-term debt and current installments of long-term debt and long-term debt.
(9) Includes the $0.02 per share effect of the March 1995 preferred conversion payment related to the conversion of 923,862 shares of the Company's $2.25 Convertible Exchangeable Preferred Stock. The payment of $1,524,000 was accounted for as a reduction of net earnings applicable to common shares when calculating the net loss per common share.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
GENERAL
The following discussion is intended to assist in understanding the Company's financial position as of December 31, 1995 and 1994, and its results of operations for each of the three years in the period ended December 31, 1995. Reference is also made to the Consolidated Financial Statements and the Notes thereto, included elsewhere herein, which should be read in conjunction with this discussion.
For information regarding a proposed acquisition by the Company, see "Business - Recent Developments - Letter of Intent to Purchase Assets of Neddrill."
OUTLOOK
The Company's operating strategy has been to pursue drilling opportunities in the U.S. and various international markets. Worldwide drilling conditions vary substantially from region to region; however, the Company operates in many markets where there is a demand for offshore rigs. During late 1992, U.S. natural gas prices improved, resulting in greater demand and higher dayrates for drilling rigs. Increasing U.S. natural gas prices resulted in significant improvements in the U.S. Gulf of Mexico ("U.S. Gulf") rig demand and dayrates during the second half of 1993. Declining world oil prices during this period reduced rig demand outside the U.S. Gulf. As a result of declining international rig demand and improved market conditions in the U.S. Gulf, many contractors mobilized rigs from international markets to the U.S. Gulf in late 1993 and early 1994. The increased supply of drilling rigs in the U.S. Gulf more than offset the increased level of U.S. Gulf rig demand during 1994 and the first half of 1995, causing increased pressure on dayrates. By mid-year 1995, rig demand in the international arena began to strengthen. Improved political stability and strengthened world oil prices caused more favorable market conditions which led the Company to mobilize rigs out of the U.S. Gulf of Mexico to international markets. Simultaneously, the U.S. Gulf of Mexico market strengthened due to improved gas prices, subsalt drilling, and deepwater drilling.
The Company anticipates that the domestic offshore market will experience significant activity levels in the first two quarters of 1996. However, the Company is cautious and does not predict these robust levels to continue all year. The international market is anticipated to remain strong, assuming oil prices remain at current levels and the political environment remains stable. If the price of natural gas decreases in the near future, the Company's dayrates and utilization rates in the U.S. Gulf could be adversely affected. The Company can predict neither the future level of demand for its drilling services nor the future conditions in the offshore contract drilling industry.
The Company had seven offshore drilling rigs under contract and one offshore drilling rig available for bidding in Nigeria at February 26, 1996. The contracts under which the seven rigs are operating each contain provisions permitting the operator to suspend operations in the event of force majeure and to terminate the contract if the force majeure continues; however, no operator has elected to suspend operations pursuant to these provisions. The Company maintains war and political risk insurance (covering physical damage or loss up to the insured value of each rig), subject, in the case of certain coverages, to immediate termination upon certain events or upon termination by the underwriter on seven days' notice. In recent periods, the Nigerian economy has experienced high inflation. During these periods, the Company's operations were not materially affected, and the Company received timely payment for its services in U.S. dollars. Revenues from drilling activities in Nigeria accounted for approximately 14 percent and 13 percent, respectively, of the Company's operating revenues in 1995 and 1994.
The Company began to operate in Venezuela in late 1993 and currently has four rigs located in that country. Three jackup rigs were under contract with Lagoven, a subsidiary of the government-owned oil company of Venezuela, and one jackup rig was under contract with Shell Venezuela S.A. as of February 26, 1996. In recent periods, the Venezuelan economy has experienced high inflation and a shortage of foreign currency. During a banking crisis in July 1994, the Venezuelan government imposed a program of currency exchange controls and taxes on certain financial transactions that temporarily limited the ability of the government-owned oil companies and their affiliates to make payment in U.S. dollars or other hard currencies to oilfield service contractors. During this period, the Company's operations were not materially affected, and the Company received timely payment for its services in U.S. dollars. Although timely U.S. dollar payments are currently being made to the Company, future exchange control actions of the Venezuelan government could adversely
affect the Company's operations in Venezuela. Revenues from drilling activities in Venezuela accounted for approximately 10 percent of the Company's operating revenues in each of 1995 and 1994.
LIQUIDITY AND CAPITAL RESOURCES
The Company had working capital of $101,623,000 and $157,885,000 as of December 31, 1995 and 1994, respectively. The decrease in working capital of $56,262,000 was primarily due to 1995 capital expenditures of $87,428,000 offset by cash provided by operating activities. The ratio of current assets to current liabilities at December 31, 1995, was 2.18:1 compared to 2.92:1 at December 31, 1994. The decrease in the current ratio was primarily the result of decreased cash and marketable securities utilized for capital projects during 1995. In addition, the Company had long-term debt related to the financing of the Company's insurance package, of which the short-term portion was $11,690,000 at December 31, 1995. The ratio of long-term debt to long-term debt plus shareholders' equity was 0.20:1 and 0.19:1 at December 31, 1995, and December 31, 1994, respectively.
The Company continues to have cash requirements for debt interest and principal payments, and for preferred dividends, when and if declared. In 1996, debt interest and principal payments are estimated to be approximately $23,900,000. Cumulative dividends on the 4,025,000 outstanding shares of Noble Drilling's $1.50 Convertible Preferred Stock ("$1.50 Preferred Stock") are estimated to be approximately $6,038,000 for 1996. The Company expects to fund these 1996 obligations of $29,938,000 out of cash and short-term investments as well as cash expected to be provided by operations.
At December 31, 1995, the Company had planned capital expenditures for 1996 of approximately $66,000,000 related to upgrades of several drilling rigs and replacements of equipment and drill pipe. The Company expects to fund these improvements to its assets out of cash provided by operations, to the extent available, and/or existing cash balances.
CREDIT FACILITIES AND LONG-TERM DEBT
On November 3, 1995, the Company entered into a financing agreement with Transamerica Insurance Finance for a period of 18 months related to the renewal of its Marine Package, Protection and Indemnity, and Excess Liability insurance policies. The amount financed totaled $16,561,000 at a fixed interest rate of 6.23 percent.
On June 16, 1994, the Company entered into a credit agreement with First Interstate Bank of Texas, N.A. for a $25,000,000 revolving credit facility and a $5,000,000 letter of credit facility (see Note 5 of Notes to Consolidated Financial Statements included elsewhere herein). At December 31, 1995, the Company had lines of credit totaling $26,000,000 and letter of credit facilities aggregating $5,000,000, subject to the Company's maintenance of certain levels of collateral. Based on the levels of collateral at December 31, 1995, the Company had $26,000,000 available under these lines of credit and $895,000 available to support the issuance of letters of credit. No amounts were outstanding under the lines of credit at December 31, 1995.
In 1993, the Company issued $125,000,000 aggregate principal amount of 9 1/4% Senior Notes Due 2003 (the "Senior Notes"), which will mature on October 1, 2003. Interest on the Senior Notes is payable semi-annually on April 1 and October 1 of each year. The Senior Notes are redeemable at the option of the Company, in whole or in part, on or after October 1, 1998 at 103.47 percent of the principal amount, declining ratably to par on or after October 1, 2001, plus accrued interest. Mandatory sinking fund payments of 25 percent of the original principal amount of the Senior Notes at par plus accrued interest will be required on October 1, 2001 and October 1, 2002. The indenture governing the Senior Notes contains certain restrictive covenants, including limitations on additional indebtedness and the ability to secure such indebtedness, restrictions on dividends and certain investments, and limitations on sale of assets, sales and leasebacks, transactions with affiliates, and merger or consolidations.
In connection with the initial construction of the NN-1, the predecessor of NN-1 Limited Partnership issued its U.S. Government Guaranteed Ship Financing Sinking Fund Bonds, of which $1,546,000 was outstanding at December 31, 1995. The bonds are secured by the vessel, and the applicable security agreement contains certain restrictions, including restrictions on distributions to partners, dispositions of assets and services to related parties. In addition, there are minimum working capital, net worth and long-term debt to net worth requirements applicable to NN-1 Limited Partnership. The Company's sharing percentage in NN-1 Limited Partnership's distributions from operations is generally 90 percent.
Minimum principal payments on the long-term debt as described above are $12,210,000 in 1996, $4,417,000 in 1997, $506,000 in 1998, and $125,000,000 due in 2003.
SUBSEQUENT EVENTS
In March 1995, Statement of Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, was issued. This statement requires that long-lived assets and certain identifiable intangibles held and used by an entity be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company adopted this standard effective January
1, 1996. The Company expects the adoption of this standard to require a charge to net income of approximately $7,000,000 in the first quarter of 1996.
Subsequent to December 31, 1995, the Company sold for cash a posted barge rig located in the U.S. Gulf of Mexico. The Company will record a gain on the sale of this asset of approximately $4,815,000 in the first quarter of 1996.
RESULTS OF OPERATIONS
The following table sets forth selected consolidated financial information of the Company expressed as a percentage of total operating revenues for the periods indicated.
- -------------------
(1) Consists of minority interest in 1995 and 1993 and minority interest and restructuring charges in 1994.
1995 COMPARED WITH 1994
OPERATING REVENUES. During 1995, the Company generated operating revenues of $327,968,000 compared to operating revenues of $351,988,000 in 1994. This decrease of $24,020,000 was due primarily to reduced contract drilling services revenue caused by a softening of market conditions in the U.S. Gulf of Mexico and Canada. This decrease was partially offset by increased turnkey engineering and consulting services revenues.
The Company's contract drilling fleet statistics are shown below.
Labor contract drilling services revenue decreased by $1,067,000 due to the decrease in labor contracts and fewer operating days in the U.K.
Turnkey drilling services revenues were $71,273,000 in 1995, compared to $56,380,000 in 1994, an increase of $14,893,000. Twenty-seven wells were completed in 1995, compared to twenty-eight in 1994. The increase in revenues was due to completion of turnkey wells of longer duration in 1995. In 1995, the average turnkey well was drilled in 50 days compared to the 1994 average of 30 days. Triton's turnkey success ratio deteriorated in 1995, primarily because of significant operational problems on two domestic wells which caused losses of $7,293,000.
Engineering and consulting revenues increased from $3,796,000 in 1994 to $11,264,000 in 1995. The increase of $7,468,000 is mainly attributable to bonus revenues generated from the alliance program ("Alliance") between the Company and Lagoven, a subsidiary of the government-owned oil company in Venezuela.
OPERATING COSTS. Operating costs ("Operating Costs") consist of operating costs and expenses other than depreciation and amortization, selling, general and administrative costs, minority interest and restructuring charges. Operating Costs were $240,102,000, or 73 percent of operating revenues, during 1995 compared to $243,208,000, or 69 percent of operating revenues, in 1994. Contract drilling services costs in 1995 decreased $21,769,000 from 1994 as a result of reduced offshore activity levels, primarily in the U.S. Gulf of Mexico and the Bay of Campeche, Mexico.
Labor contract drilling services costs in 1995 decreased $1,815,000 as compared to 1994. This decrease was due to a reduced number of operating days in 1995 compared to 1994.
Turnkey drilling services costs increased $17,585,000 during 1995. As noted above, Triton's average turnkey well drilling time increased in 1995, partially due to operational issues on certain domestic wells. These operational issues were also the primary cause of the decline in turnkey profit margins to 10 percent in 1995 compared to 17 percent in 1994.
Engineering and consulting services costs in 1995 increased $4,353,000 from 1994. This increase was due primarily to the fact that the 1994 costs only include amounts from the date the Company acquired Triton in April 1994 through year end.
DEPRECIATION AND AMORTIZATION EXPENSE. Depreciation and amortization expenses were $36,492,000 in 1995 compared to $39,519,000 in 1994. The decrease of $3,027,000 was primarily due to a change in accounting estimates offset by the effects of 1995 capital spending. Effective January 1, 1995, the estimated salvage values and remaining depreciable lives of certain rigs were adjusted to better reflect their economic lives and to be consistent with other similar assets owned by the Company. The effect of this change in estimate was a decrease in depreciation and amortization of $6,160,000, or $0.07 per share.
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative ("SG&A") expenses were $40,139,000 during 1995 as compared to $47,606,000 in 1994, a decrease of $7,467,000. SG&A expenses decreased from 1994 due in part to reductions in overhead achieved as a result of restructuring and consolidation efforts. The 1994 SG&A expenses included approximately $5,300,000 in pooling expenses related to the Chiles Merger.
RESTRUCTURING CHARGES. A restructuring charge of $3,661,000 related to the Chiles Merger was recorded in 1994 as a result of facility consolidation, including the write-down of certain of the Company's owned properties and, to a lesser extent, severance costs.
OTHER, NET. Other, net was $250,000 during 1995 compared to $15,743,000 during 1994. This decrease was principally due to the 1994 gain of $8,000,000 on the sale of a drilling rig, net unrealized gains of $4,162,000 on marketable equity investments, and a gain of $1,530,000 on the recovery of a previously written-off note receivable, offset by realized losses on marketable debt securities of $2,199,000.
INCOME TAX PROVISION. Provisions for income taxes of $3,272,000 and $5,672,000 were recorded in 1995 and 1994, respectively. This decrease was primarily due to a $2,100,000 U.S. separate return year loss carryback benefit recorded by Triton.
At December 31, 1995, the Company had approximately $6,000,000 in withholding tax receivables related to withholding taxes in Nigeria. Management believes that this amount will be realized by obtaining the required tax certificates from the related operators.
1994 COMPARED WITH 1993
OPERATING REVENUES. During 1994, the Company generated operating revenues of $351,988,000 compared to operating revenues of $264,531,000 in 1993. This increase of $87,457,000 was due primarily to the acquisition of Triton and to recording a full year's revenue from the assets purchased from The Western Company of North America in October 1993. The Company's contract drilling fleet statistics are shown below.
Labor contract drilling services revenue increased by $1,729,000 in 1994 due to the increased number of labor contracts compared to 1993.
Turnkey drilling services revenues were $56,380,000 in 1994, which represents revenue from the date of the acquisition of Triton. Twenty-eight wells were completed in 1994, subsequent to the acquisition of Triton, for average revenues per completed well of approximately $2,000,000.
The 1994 increases in engineering and consulting services revenues and other revenue of $1,504,000 and $1,345,000, respectively, were primarily due to the Triton acquisition.
OPERATING COSTS. Operating Costs were $243,208,000, or 69 percent of operating revenues, during 1994, compared to $178,684,000, or 68 percent of operating revenues, in 1993. The increase in Operating Costs is due to the increase in turnkey drilling services expense and the increase in operating days as discussed above.
DEPRECIATION AND AMORTIZATION EXPENSE. Depreciation and amortization expenses were $39,519,000 in 1994, as compared to $28,886,000 in 1993. The increase of $10,633,000 was principally due to a full year's depreciation on the assets purchased from Western in October 1993 and the increase of approximately $35,000,000 in capital expenditures compared to 1993.
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. SG&A expenses were $47,606,000 during 1994, as compared to $28,284,000 in 1993, an increase of $19,322,000. SG&A expenses increased from 1993 due to the Triton acquisition ($7,800,000), pooling expenses related to the Chiles Merger ($5,300,000), and a full year of administrative expense from the Venezuela and Zaire operations ($2,800,000), with the balance due to an increased level of corporate personnel.
RESTRUCTURING CHARGES. A restructuring charge of $3,661,000 related to the Chiles Merger was recorded in 1994 as a result of facility consolidation, including the write-down of certain of the Company's owned properties and, to a lesser extent, severance costs.
INTEREST EXPENSE, NET OF INTEREST INCOME. Interest expense, net of interest income, was $6,711,000 in 1994, as compared to net interest expense of $5,541,000 in 1993. This increase in net interest expense was due to increased interest expense of $4,313,000 related to the issuance of the Senior Notes in October 1993, partially offset by additional interest income of $3,143,000. The increase in interest income is attributable to the cash proceeds from Chiles' preferred stock offering in October 1993 (see Note 6 of Notes to Consolidated Financial Statements included elsewhere herein).
OTHER, NET. Other, net was $15,743,000 during 1994, compared to $1,047,000 in 1993. This increase was principally due to a gain of $8,000,000 on the sale of a drilling rig, net unrealized gains of $4,162,000 on marketable equity investments, and a gain of $1,530,000 on the recovery of a previously written-off note receivable, offset by realized losses on marketable debt securities of $2,199,000.
INCOME TAX PROVISION. Provisions for income taxes of $5,672,000 and $3,333,000 were recorded in 1994 and 1993, respectively. This increase was due to the foreign deferred tax provision of $3,073,000 in 1994, related to the book and tax depreciation differences for the assets deployed in Venezuela and Mexico.

NOTE 1 -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
ORGANIZATION AND BUSINESS
Noble Drilling Corporation ("Noble Drilling" or, together with its consolidated subsidiaries, unless the context requires otherwise, the "Company") is primarily engaged in domestic and international contract oil and gas drilling and workover operations. The Company's international operations are conducted in the United Kingdom, Nigeria, Zaire, India, Venezuela, Mexico, Canada, and Qatar. On September 15, 1994, Chiles Offshore Corporation ("Chiles") merged with Noble Offshore Corporation ("NOC"), a wholly owned subsidiary of Noble Drilling (the "Chiles Merger"). See Note 2.
The contract drilling industry is a highly competitive and cyclical business characterized by high capital and maintenance costs. Although conditions in recent years in the oil and gas industry have precipitated consolidation of industry participants, there remains an oversupply of drilling equipment. As a consequence, there has been intense competition for available drilling contracts resulting in equipment being idle for long periods of time and at generally unfavorable terms and prices for contract drilling.
The Company follows a policy of keeping its equipment well maintained and technologically competitive. However, its equipment could be made obsolete by the development of new techniques and equipment. In addition, industry-wide shortages of supplies, services, skilled personnel, and equipment necessary to conduct the Company's business, such as drill pipe, have occurred from time to time in the past and such shortages could occur again.
The Company's operations are subject to the many hazards inherent in the drilling business, including blowouts, cratering, fires and collisions or groundlings of offshore equipment, which could cause substantial damage to the environment. In addition, the Company's operations are subject to damage or loss from adverse weather and seas. These hazards could cause personal injury and loss of life, suspend drilling operations or seriously damage or destroy the property and equipment involved and, in addition to the environmental damage, could cause substantial damage to producing formations and surrounding areas. Although the Company maintains insurance against many of these hazards, such insurance is subject to substantial deductibles and provides for premium adjustments based on claims. It also excludes certain matters from coverage, such as loss of earnings on certain rigs.
Under turnkey drilling contracts, Triton Engineering Services Company ("Triton") generally assumes the risk of pollution and environmental damage, but on occasion receives indemnification from the customer for environmental and pollution liabilities in excess of Triton's pollution insurance coverage. Further, Triton is not insured against certain drilling risks that could result in delays or nonperformance of a turnkey drilling contract, although it generally maintains insurance against delays related to loss of well control.
The Company's international operations are also subject to certain political, economic and other uncertainties including, among others, risks of war and civil disturbances, expropriation, nationalization, renegotiation or modification of existing contracts, taxation policies, foreign exchange restrictions, international monetary fluctuations and other hazards arising out of foreign governmental sovereignty over certain areas in which the Company conducts operations. The Company has insurance covering expropriation and other political risks to the extent available to the Company at rates it considers prudent to pay.
CONSOLIDATION
The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and the Company's share of the assets, liabilities and operations of Perforadora Faja de Oro, S.A. de C.V. ("Faja Joint Venture") and NN-1 Limited Partnership, of which the Company is the general partner. The minority interest in Faja Joint Venture (10 percent) and NN-1 Limited Partnership (approximately 10 percent) is included in the balance sheets and the statements of operations as minority interest. In 1994, the Company made distributions of $4,500,000 to its partner in Faja Joint Venture. All significant intercompany accounts and transactions have been eliminated in consolidation.
Certain reclassifications have been made in the 1994 and 1993 consolidated financial statements to conform to the classifications used in the 1995 consolidated financial statements. These reclassifications have no impact on net income or loss.
FOREIGN CURRENCY TRANSLATION
The Company follows a translation policy in accordance with Statement of Financial Accounting Standards ("SFAS") No. 52, Foreign Currency Translation. The U.S. dollar has been designated as the functional currency where appropriate, based on an evaluation of such factors as the markets in which the subsidiary operates, generation of cash flow, financing

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
activities and intercompany arrangements. For the Company's subsidiaries in the United Kingdom and Canada, the local currency is the functional currency. Assets and liabilities are translated at the rates of exchange on the balance sheet date. Income and expense items are translated at average rates of exchange. The resulting gains or losses arising from the translation of accounts from the functional currency to the U.S. dollar are included as a separate component of shareholders' equity designated as cumulative translation adjustment.
CASH AND CASH EQUIVALENTS
Cash and cash equivalents include cash on hand, demand deposits with banks and all highly liquid investments with original maturities of three months or less.
In accordance with SFAS No. 95, Statement of Cash Flows, cash flows from the Company's operations in the United Kingdom and Canada are calculated based on their functional currency. As a result, amounts related to assets and liabilities reported on the Consolidated Statements of Cash Flows will not necessarily agree with changes in the corresponding balances on the Consolidated Balance Sheets. The effect of exchange rate changes on cash balances held in foreign currencies is reported on a separate line below cash (used in) provided by financing activities.
The restricted cash balance of $898,000 at December 31, 1994, was restricted as a result of collateral requirements imposed by a lender of the Company. This restriction was lifted in 1995.
INVESTMENT IN MARKETABLE SECURITIES
Pursuant to the cash management policy implemented in 1992, the Company invests in marketable debt securities. Effective January 1, 1994, the Company adopted SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities. The Company classifies its investments in marketable debt securities as available for sale and its investments in marketable equity securities as trading. See Note 3.
INVESTMENT IN UNCONSOLIDATED AFFILIATES
The Company uses the equity method to account for affiliates in which it does not have voting control.
INVENTORIES
Inventories of spare parts, material and supplies held for consumption are stated principally at average cost.
PROPERTY AND EQUIPMENT
Property and equipment is stated at cost, reduced by provisions to recognize economic impairment in value when management determines that such impairment has occurred. Drilling equipment and facilities are depreciated using the straight-line method over estimated remaining useful lives ranging from three to twenty-five years from the date of construction or major refurbishment. All other property and equipment is depreciated using the straight-line method over useful lives ranging from three to twenty years.
Effective January 1, 1995, the Company revised its estimates of salvage values and remaining depreciable lives of certain rigs to better reflect their economic lives and to be consistent with other similar assets owned by the Company. The effect of this change in estimates was a reduction in the net loss applicable to common shares of $6,160,000, or $0.07 per common share, for the year ended December 31, 1995.
Maintenance and repairs on drilling equipment are charged to expense as incurred. Total maintenance and repair expenses for the years ended December 31, 1995, 1994, and 1993, were approximately $26,189,000, $33,700,000, and $25,900,000, respectively. When assets are sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or loss is recognized.
In March 1995, SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, was issued. This statement requires that long-lived assets and certain identifiable intangibles held and used by an entity be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company adopted this standard effective January 1, 1996. The Company expects the adoption of this standard to require a charge to net income of approximately $7,000,000 in the first quarter of 1996.
OTHER ASSETS
In 1995, other assets primarily included deferred debt issuance costs in connection with the October 7, 1993, issuance of debt securities (see Note 4), the long-term portion of prepaid insurance costs and goodwill related to the Triton acquisition. The deferred debt issuance costs in connection with the October 7, 1993 issuance of debt securities (see Note 4)
NOBLE DRILLING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
totaled $4,015,000 and are being amortized over the life of the debt securities. The accumulated amortization at December 31, 1995 and 1994, was $864,000 and $540,000, respectively. The prepaid insurance costs totaled $3,230,000 at December 31, 1995, and are being amortized over the term of the insurance policy. The goodwill related to Triton totaled $1,775,000 at December 31, 1995, and is being amortized over seventeen years.
REVENUE RECOGNITION
Revenues generated from the Company's dayrate-basis drilling contracts are recognized as services are performed. The Company's turnkey drilling contracts are of a short-term, fixed fee nature, and accordingly, revenues and expenses are recognized using the completed contract method. When estimates of projected revenues and costs indicate a loss, the total estimated loss is accrued.
CONCENTRATION OF CREDIT RISK
The primary market for the Company's services is the offshore oil and gas industry, and the Company's customers consist primarily of major oil companies, independent oil and gas producers and government-owned oil companies. The Company performs ongoing credit evaluations of its customers and generally does not require material collateral. The Company provides allowances for potential credit losses when necessary.
NET (LOSS) INCOME APPLICABLE TO COMMON SHARES PER SHARE
Net (loss) income applicable to common shares per share has been computed on the basis of the weighted average number of common shares and, where dilutive, common share equivalents, outstanding during the indicated periods. Each outstanding share of the $2.25 Preferred Stock and $1.50 Convertible Preferred Stock ("$1.50 Preferred Stock") was assumed to be converted, at January 1, 1995, into 5.41946 and 2.4446 shares of common stock, respectively, for purposes of calculating fully diluted earnings per share. The calculation of net (loss) income applicable to common shares per share assuming full dilution was antidilutive; therefore, fully diluted amounts are not presented. The Preferred Conversion Payment of approximately $1,524,000 in March 1995 (see Note 6) was accounted for as a reduction of net earnings applicable to common shares for purposes of calculating the net loss per common share. This accounting treatment increased the net loss applicable to common shares per share from $0.06 to $0.08 for the year ended December 31, 1995. See Note 13.
CERTAIN SIGNIFICANT ESTIMATES
The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.
NOTE 2 -- ACQUISITIONS AND MERGERS
The Chiles Merger was consummated on September 15, 1994 through the exchange of 28,598,777 shares of Noble Drilling common stock for all the outstanding common stock of Chiles and the exchange of 4,025,000 shares of Noble Drilling $1.50 convertible preferred stock ("$1.50 Preferred Stock") (liquidation preference $25.00 per share), par value $1.00 per share, for all the outstanding shares of Chiles $1.50 convertible preferred stock. The Chiles Merger was accounted for as a pooling of interests and all financial information for the year of the transaction and prior periods has been restated to reflect this merger. In addition, Noble Drilling issued an additional 480,000 shares of its common stock in exchange for the cancellation of outstanding Chiles stock options.
On April 22, 1994, the Company acquired all of the issued and outstanding shares of common stock (the "Shares") of Triton pursuant to the terms of the Stock Purchase Agreement dated April 22, 1994. In consideration for the Shares, the Company paid approximately $4,085,000 in cash, issued promissory notes in the aggregate amount of $4,000,000, and issued 751,864 shares of Noble Drilling common stock valued at $5,169,000. The promissory notes were paid on October 21, 1994. In addition, the Company has a contingent obligation to pay additional consideration on April 22, 1996, including issuance of up to 254,551 shares of Noble Drilling common stock, if certain financial conditions are achieved. The acquisition of Triton has been accounted for under the purchase method, and accordingly, Triton's operating results have been included in the consolidated operating results since the date of acquisition.
The Company acquired nine mobile offshore jackup drilling rigs and associated assets (the "Western Acquisition") from The Western Company of North America ("Western") for $150,000,000 in cash on October 7, 1993. The Western

Acquisition has been accounted for under the purchase method, and accordingly, the operating results have been included in the consolidated operating results since the date of acquisition.
The following table summarizes certain unaudited pro forma condensed consolidated results of operations data that give effect to the acquisition of Triton as if it had occured on January 1, 1994 and January 1, 1993 and the acquisition of Western as it had occurred on January 1, 1993.
On September 16, 1994, the Company exchanged its interest in Grasso Corporation for 645,656 shares of common stock of Offshore Logistics, Inc. This investment is classified as a marketable equity security. See Note 3.
NOTE 3 -- MARKETABLE SECURITIES
Effective January 1, 1994, the Company adopted SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities. Under the provisions of SFAS No. 115, investments in debt and equity securities are required to be classified into one of three categories: held to maturity, available for sale or trading securities. At each reporting date, the appropriateness of such classification is required to be reassessed. Realized gains and losses on sales of investments are included in income on a specific identification basis.
As of December 31, 1995, the Company classified all of its debt securities with original maturities of more than three months as available for sale. These investments are classified as marketable securities within current assets on the accompanying consolidated balance sheets. The following table highlights information applicable to the Company's investments classified as available for sale as of December 31, 1995 and December 31, 1994:
NOBLE DRILLING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
The unrealized loss on debt securities of $115,000 and $1,847,000 as of December 31, 1995 and 1994, respectively, is included as a reduction of shareholders' equity in accordance with SFAS No. 115. Total realized losses related to short-term investments for the twelve months ended December 31, 1995 and 1994, were $15,000 and $2,199,000, respectively.
The Company categorizes its investments in marketable equity securities as trading securities. These investments are classified as current assets and were recorded at a fair value of $6,131,000 at December 31, 1995. Total proceeds from the sale of these securities were $3,670,000 and $0 for the years ended December 31, 1995 and 1994, respectively. Total realized gains on these equity investments for the years ended December 31, 1995 and 1994 were $371,000 and $0, respectively. Total net unrealized (losses) and gains related to these equity investments for the years ended December 31, 1995 and 1994, were $(56,000) and $4,162,000, respectively.
NOTE 4 -- DEBT
On November 3, 1995, the Company entered into a financing agreement with Transamerica Insurance Finance for a period of eighteen months related to the renewal of its Marine Package, Protection and Indemnity, and Excess Liability insurance policies. The amount financed totaled $16,561,000 at a fixed interest rate of 6.23 percent per annum.
On October 14, 1993, the Company prepaid a promissory note with proceeds from the Public Offerings (as defined below). The terms of the note provided that interest did not accrue from September 1, 1991 through December 31, 1992, after which date interest on the unpaid principal amount accrued at a fixed rate of 7.5 percent per annum. The Company had accrued interest on the note at 4.9 percent for all periods, which was the imputed rate based on the revised note terms. An extraordinary gain of $1,770,000 for extinguishment of debt was recognized in 1993 (see Note 10) from the prepayment of the note, representing excess accrued interest.
On October 7, 1993, in connection with the Western Acquisition and the issuance of 12,041,000 shares of Noble Drilling common stock in an underwritten public offering (the "Stock Offering") (see Note 6), the Company issued $125,000,000 principal amount of 9 1/4% Senior Notes Due 2003 ("Senior Notes") (the Stock Offering and the issuance of Senior Notes are collectively referred to as the "Public Offerings"). The Senior Notes will mature on October 1, 2003. Interest on the Senior Notes is payable semi-annually on April 1 and October 1 of each year. The Senior Notes are redeemable at the option of the Company, in whole or in part, on or after October 1, 1998 at 103.47 percent of principal amount, declining ratably to par on or after October 1, 2001, plus accrued interest. Mandatory sinking fund payments of 25 percent of the original principal amount of the Senior Notes at par plus accrued interest will be required on October 1, 2001 and October 1, 2002. The indenture governing the Senior Notes contains certain restrictive covenants, including limitations on additional indebtedness and the ability to secure such indebtedness, restrictions on dividends and certain investments and limitations on sales of assets, sales and leaseback, transactions with affiliates, and mergers or consolidations.
In connection with the initial construction of the NN-1, the predecessor of NN-1 Limited Partnership issued U.S. Government Guaranteed Ship Financing Sinking Fund Bonds, of which $1,546,000 principal amount was outstanding at December 31, 1995. The bonds mature in 1998, and bear interest at the rate of 8.95 percent per annum, payable semi-annually on June 15 and December 15. The bonds are secured by the vessel, and the applicable security agreement contains certain restrictions, among others, on distributions to partners, dispositions of assets and services to related parties. In addition, there are minimum working capital, net worth and long-term debt to net worth requirements applicable to NN-1 Limited Partnership. The net book value of the vessel at December 31, 1995, was $12,131,000. The Company's sharing percentage in NN-1 Limited Partnership's distribution from operations is generally 90 percent. The NN-1 has not been under contract since March of 1993.
The Company and its wholly owned subsidiary, Noble Drilling (West Africa) Inc. ("NDWA"), were parties to a secured loan agreement (the "Project Loan Agreement") with US WEST Financial Services, Inc. dated as of October 31, 1990, as amended, pursuant to which NDWA borrowed $52,500,000 for the purpose of financing, in part, the equipping, refurbishment and mobilization to Nigeria of four offshore drilling rigs: the NN-1, Gene Rosser, Lewis Dugger and Chuck Syring. On July 2, 1993, the final installment of $6,562,000 plus accrued interest was paid in accordance with the terms of the Project Loan Agreement. Interest was charged under the Project Loan Agreement at the fixed rate of 11.12 percent per annum.
Annual maturities of long-term debt are $12,210,000 in 1996, $4,417,000 in 1997, $506,000 in 1998, and $125,000,000 due in 2003.
NOBLE DRILLING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
The following table summarizes the Company's long-term debt:
The fair value of the Company's long-term debt at December 31, 1995, estimated based on the quoted market prices for similar issues or on the current rates offered to the Company for debt of similar remaining maturities, was approximately $130,300,000.
NOTE 5 -- CREDIT FACILITIES
At December 31, 1995, the Company had available credit facilities aggregating $31,000,000, as described below, of which $26,000,000, subject to certain limitations, is related to lines of credit and $5,000,000 is related to letter of credit facilities. Based on the level of the borrowing base at December 31, 1995, the Company had $26,000,000 available under the credit lines and $895,000 available to support issuance of letters of credit at that date.
The Company has an unsecured credit agreement with First Interstate Bank of Texas, N.A., which provided for a $25,000,000 revolving credit line facility and $5,000,000 letter of credit facility at December 31, 1995. The Company pays a quarterly commitment fee on the unused portion of the facility. The agreement contains certain restrictive and financial covenants, including those related to indebtedness, net worth and fixed charges, and provides for guarantees of the indebtedness by certain subsidiaries of Noble Drilling.
NOTE 6 -- SHAREHOLDERS' EQUITY
On October 25, 1993, the Company issued 626,410 shares of common stock to purchase two rigs from Portal as discussed in Note 12. The shares were issued to Portal pursuant to a private placement, and the Company does not have an obligation to register the resale of the shares under the Securities Act of 1933, as amended.
Chiles completed a public offering of $1.50 convertible preferred stock on October 21, 1993 with the sale and issuance to the public of 4,025,000 shares by Chiles at $25.00 per share. Net proceeds to Chiles were approximately $96,500,000 after underwriting discounts and issuance costs. Chiles utilized approximately $45,200,000 of these proceeds to retire all of Chiles' outstanding long-term indebtedness, including principal and interest, during the fourth quarter of 1993. In the Chiles Merger, this series of preferred stock was converted into and exchanged for an equivalent number of shares of $1.50 Preferred Stock having substantially the same rights, privileges, preferences and voting power as the Chiles preferred stock. Holders of the $1.50 Preferred Stock are entitled to receive cumulative cash dividends at an annual rate of $1.50 per share, when, as and if declared by the board of directors of Noble Drilling, payable quarterly. Each share of $1.50 Preferred Stock is convertible, at the option of the holder, into 2.4446 shares of common stock (subject to adjustment in certain circumstances). The $1.50 Preferred Stock is not redeemable prior to December 31, 1996. On or after such date, the $1.50 Preferred Stock is redeemable at the option of the Company, in whole or part, at $26.05 per share if redeemed prior to December 31, 1997, and at prices decreasing in increments of $0.15 per year to $25.00 per share on and after December 31, 2003, plus accrued and unpaid dividends to the redemption date.
On October 7, 1993, the Company issued and sold 12,041,000 shares of common stock in the Stock Offering (see Note 4) at an initial offering price of $8.375 per share. This resulted in net proceeds of $94,900,000, after deducting underwriting discounts, commissions and other related costs. The net proceeds of the Public Offerings (see Note 4) were used to purchase the nine jackup rigs and related assets discussed previously in Note 2, and to prepay a promissory note discussed in Note 4, with the balance of the proceeds, approximately $26,000,000, used for general corporate purposes.
In 1991, the Company issued and sold 2,990,000 shares of a new series of $2.25 Convertible Exchangeable Preferred Stock ("$2.25 Preferred Stock"), par value $1.00 per share. Holders of the $2.25 Preferred Stock received a cash dividend at an annual rate of $2.25 per share. In March 1995, an aggregate of 923,862 shares of $2.25 Preferred Stock were
NOBLE DRILLING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
converted into 5,006,830 shares of Noble Drilling common stock. The Company paid an aggregate of approximately $1,524,000 in cash ("Preferred Conversion Payment") in the first quarter in connection with this conversion. In the second quarter of 1995, the Company called for the redemption of all remaining outstanding shares of the $2.25 Preferred Stock. Of the 2,065,238 shares then outstanding, 2,062,537 were surrendered for conversion and 2,701 were redeemed by the Company, resulting in the Company's issuance of 11,192,359 shares of common stock (including 14,637 shares sold to a standby underwriter).
NOTE 7 -- STOCK OPTIONS
1991 STOCK OPTION PLAN
The Company's 1991 Stock Option and Restricted Stock Plan (the "1991 Plan") was amended and restated ("Amended 1991 Plan") in September 1994. The Amended 1991 Plan was adopted by the board of directors of Noble Drilling in July 1994 and approved by stockholders on September 15, 1994. The Company's two other employee stock option plans, adopted in 1985 and 1987, were amended in connection with the adoption of the 1991 Plan to provide that no further grants would be made under those plans after April 25, 1991; however, all options outstanding at that date ("Pre-1991 Options") remained in effect in accordance with their respective terms.
Under the Amended 1991 Plan, a maximum of 5,200,000 shares of the Company's common stock may be subject to grants of options or awards of restricted stock to participants, who are selected from regular salaried officers or other employees of the Company. Options may be either incentive options or nonqualified options, and may be with or without stock appreciation rights ("SARs"). The option price under the Amended 1991 Plan may not be less than 100 percent of the fair market value of the common stock at the time of grant, in the case of an incentive option, and may not be less than 50 percent of the fair market value of the common stock at the time of grant, in the case of a nonqualified option. The Amended 1991 Plan also limits to 1,500,000 the total number of shares of common stock that may be made subject to grants of options or stock appreciation rights or awards of restricted stock to any one person during any five-year period. All Pre-1991 Options were granted at an option price of at least 100 percent of the fair market value of the common stock at the time of grant. The exercise of either the tandem SAR or the option serves to cancel the other. At December 31, 1995, 2,571,767 shares were available for grant under the Amended 1991 Plan.
As of January 1, 1995, there were 250,000 shares of common stock held by the Company as treasury shares. During February 1995, 211,500 treasury shares were issued to certain employees pursuant to the terms of the Amended 1991 Plan and the applicable restricted stock agreements. The issued shares of restricted stock have been placed in escrow subject to satisfaction of various performance criteria during a three-year period. In June 1995, 26,000 of these shares were returned to treasury stock following the resignation of one employee. As of December 31, 1995, 64,500 shares were held as treasury stock. Subsequent to December 31, 1995, 250,000 shares of common stock were purchased by the company and returned to treasury stock, increasing the balance of treasury stock to 314,500 shares. In January 1996, 108,750 shares of treasury stock were issued to certain employees as restricted stock under the Amended 1991 Plan and have been placed in escrow under the aforementioned terms.
The following is a summary of option transactions under the plans:
Options granted in 1995 under the Amended 1991 Plan become exercisable on certain dates that range from February 2, 1996, through February 2, 1998, at a price $5.188 per share.
NOBLE DRILLING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
OTHER STOCK OPTIONS
During 1987, in addition to the options described above, options to purchase a total of 300,000 shares of Noble Drilling's common stock at $2.50 per share were granted to certain non-employee directors of the Company pursuant to stock option agreements which were approved by stockholders at the 1988 annual meeting. Options to purchase 160,000 shares were outstanding and exercisable at December 31, 1995.
In 1993, the stockholders approved the 1992 Nonqualified Stock Option Plan for Non-Employee Directors (the "1992 Option Plan"). Under the 1992 Option Plan, non-employee directors received a one-time grant of an option to purchase 10,000 shares of common stock, and thereafter, after each annual meeting of shareholders of the Company, receive an annual grant of an option to purchase 3,500 shares of common stock. The options are granted at fair market value on the grant date and are exercisable from time to time over a period commencing one year from the grant date and ending on the expiration of ten years from the grant date, unless terminated sooner as described in the 1992 Option Plan. Options to purchase 77,500 shares were outstanding and exercisable at December 31, 1995.
SFAS NO. 123 - ACCOUNTING FOR STOCK-BASED COMPENSATION
In October 1995, SFAS No. 123, Accounting for Stock-Based Compensation, was issued. This statement establishes financial accounting and reporting standards for stock-based employee compensation plans. Those plans include all arrangements by which employees receive shares of stock or other equity instruments of the employer or the employer incurs liabilities to employees in amounts based on the price of the employer's stock. The Company adopted this standard effective January 1, 1996. As provided in the statement, the Company elected to continue to measure compensation cost using the guidelines of APB Opinion No. 25 and to include disclosures of net income and earnings per share as if the fair value based method of accounting were utilized.
STOCKHOLDER RIGHTS PLAN
The Company adopted a stockholder rights plan on June 28, 1995, designed to assure that the Company's stockholders receive fair and equal treatment in the event of any proposed takeover of the Company and to guard against partial tender offers and other abusive takeover tactics to gain control of the Company without paying all stockholders a fair price. The rights plan was not adopted in response to any specific takeover proposal. Under the rights plan, the Company declared a dividend of one right ("Right") on each share of Noble Drilling common stock. Each Right will entitle the holder to purchase one one-hundredth of a share of a new Series A Junior Participating Preferred Stock, par value $1.00 per share, at an exercise price of $35.00. The Rights are not currently exercisable and will become exercisable only in the event a person or group acquires beneficial ownership of 15 percent or more of Noble Drilling common stock. The dividend distribution was made on July 10, 1995 to stockholders of record at the close of business on that date. The Rights will expire on July 10, 2005.
NOTE 8 -- INCOME TAXES
The Company follows SFAS No. 109, Accounting for Income Taxes, which requires the use of the liability method of accounting for deferred income taxes. Under SFAS No. 109, deferred tax assets and liabilities are recognized based upon differences between the financial statement and tax bases of assets and liabilities using presently enacted tax rates. If it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is recognized.
Amounts of deferred tax assets and liabilities are as follows at:

NOBLE DRILLING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
A reconciliation of Federal statutory and effective income tax rates is shown below:
The Company had available at December 31, 1995, unused investment tax credits, which may be used to offset future U.S. taxes payable, of $1,457,000 expiring in various years from 1998 to 2001. In addition, Noble Drilling had net operating loss carryforwards ("NOLs") for tax purposes of approximately $145,902,000 at December 31, 1995, which expire in the years 2000 through 2010, and NOC has NOLs for tax purposes of approximately $67,756,000 which expire in the years 2004 through 2009.
The Chiles Merger qualifies as a tax-free reorganization. NOC, as the surviving entity, inherited all of Chiles' tax attributes, including NOL carryforwards. In accordance with the "Separate Return Limitation Year" rules of the Internal Revenue Code of 1986, as amended (the "Code"), Chiles' NOL carryforwards may only be used to reduce Noble Drilling's future taxable income to the extent of NOC's taxable income.
If a corporation undergoes an "ownership change" within the meaning of Section 382 of the Code, the corporation's right to use its then existing NOLs (and certain other tax attributes) is limited during each future year to a percentage of the fair market value of such corporation's stock immediately before the ownership change (the "Section 382 Limitation"). In general, there is an "ownership change" under Section 382 if over a three-year period certain shareholders increase their percentage ownership of a corporation by more than 50 percent. To the extent the amount of the NOLs existing at the time of an ownership change that are used in any subsequent year is less than the annual Section 382 Limitation, the otherwise available Section 382 Limitation is correspondingly increased for future years. An ownership change for purposes of Section 382 took place on September 15, 1994, as a result of the Chiles Merger. The cumulative Section 382 Limitation attributable to the Noble Drilling pre-merger carryforwards is $47,231,000. The cumulative Section 382 Limitation attributable to NOC is $22,185,000.
Applicable U.S. income and foreign withholding taxes have not been provided on undistributed earnings of the Company's international subsidiaries. Management does not intend to repatriate such undistributed earnings for the foreseeable future except for distributions upon which incremental income taxes would not be material.

Rent expense was $1,918,000, $1,200,000, and $1,297,000 for 1995, 1994, and 1993, respectively.
Withholding tax receivables include approximately $6,000,000 related to withholding taxes in Nigeria. To recognize these receivables, the Company must receive tax certificates from the applicable operators. Management believes that the full amount of these receivables will be realized.
Operating costs and mobilization for the year ended December 31, 1995 consists of costs incurred in mobilizing rigs from the U.S. Gulf of Mexico to various international locations. Such costs are amortized over the term of the related contract.
Other income - other, net consisted of the following:
On December 15, 1995, the Linn Richardson, a 250-foot mat slot rig, lost overboard approximately 200 feet of leg while under tow to perform a contract offshore Senegal, Africa. On the following day, the rig lost overboard approximately 240 feet of a second leg which also caused damage to equipment and facilities on the deck of the rig. Pursuant to a preliminary assessment plan developed jointly by the Company and its insurance underwriters, the third leg of the rig has been removed and the rig has been towed to the U.S. Gulf of Mexico where a complete evaluation will take place. A charge of $1,778,000 related to the cost of mobilizing the rig to Senegal was accrued in the fourth quarter of 1995. This amount represents management's best estimate of the total loss. Management does not believe this incident will have any other material adverse effect on its financial condition or results of operations.
A restructuring charge of $3,661,000 related to the Chiles Merger was recorded in 1994 as a result of facility consolidation, including the write-down of certain of the Company's owned properties, and to a lesser extent severance costs. This restructuring plan was developed in the fourth quarter of 1994 and approved by the board of directors of Noble Drilling.
NOTE 10 -- EXTRAORDINARY ITEM
The Company prepaid a promissory note in the fourth quarter of 1993 with proceeds from the Public Offerings (see Notes 4 and 6). This prepayment resulted in an extraordinary gain from extinguishment of debt of $1,770,000 ($0.02 per common share), representing excess accrued interest.

NOTE 11 -- EMPLOYEE BENEFIT PLANS
The Company has a noncontributory defined benefit plan which covers substantially all salaried employees and a noncontributory defined benefit pension plan which covers certain field employees. The benefits from these plans are based primarily on years of service and employees' compensation near retirement. The Company's funding policy is consistent with funding requirements of applicable laws and regulations. The assets of these plans consist of corporate equity securities, municipal and government bonds, and cash equivalents. The Company, when required, makes contributions to the domestic plan in the form of Noble Drilling common stock. As of September 30, 1995, the domestic plan assets included $2,067,000 of Noble Drilling's common stock valued at fair value at that date. The Company changed the measurement date of the plan to September 30 beginning in 1995. This change did not have a material impact to the financial results of the Company.
Noble Drilling (U.K.) Limited, a wholly owned subsidiary of Noble Drilling, maintains a pension plan which covers all of its salaried, nonunion employees. Benefits are based on credited service and the average of the highest three years of qualified salary within the past ten years of participation.
Pension cost includes the following components:
The funded status of the plans is as follows:
In accordance with SFAS No. 87, Employers' Accounting for Pensions, the Company recorded an additional minimum liability of $3,403,000 and $3,825,000 at December 31, 1995 and 1994, respectively. This liability represents the excess of the accumulated benefit obligations over the fair value of plan assets and accrued pension liabilities of the domestic salaried pension plan. This additional minimum pension liability is reported as a separate reduction of shareholders' equity.

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts)
The projected benefit obligations for the international and domestic plans were determined using an assumed discount rate of 8.5 percent and 7.5 percent, respectively, in 1995, 9.0 percent and 8.5 percent, respectively, in 1994 and 8.0 percent and 7.25 percent, respectively, in 1993. Assumed long-term rate of return on international plan assets was 9.25 percent, 9.75 percent and 8.75 percent in 1995, 1994 and 1993, respectively. Assumed long-term rate of return on domestic plan assets was 9.0 percent in each of the years presented. The projected benefit obligations for the international plan assume a compensation increase of 6.25 percent, 6.75 percent and 5.75 percent in 1995, 1994 and 1993, respectively, and 6.0 percent per annum for the domestic plan in each of the years presented.
The Company presently sponsors medical and other plans for the benefit of its employees. The cost of maintaining these plans aggregated $6,628,000, $5,500,000, and $3,793,000 in 1995, 1994, and 1993, respectively.
The Company does not provide post-retirement benefits (other than pensions) or any post-employment benefits to its employees.
NOTE 12 -- COMMITMENTS, CONTINGENCIES AND OBLIGATIONS
On October 25, 1993, the Company purchased two submersible offshore drilling rigs from Portal Rig Corporation ("Portal") for 626,410 shares of Noble Drilling common stock. The Company acquired the rigs subject to certain federal income tax "safe harbor leases" and a related preferred ship mortgage relating to a tax benefit transaction entered into in 1982 by a predecessor of Portal. Portal has agreed to indemnify the Company for any potential liabilities as a result of this earlier tax benefit transaction.
During 1993, Chiles entered into severance agreements with its officers and certain managerial employees, including Chiles' rig management personnel. These agreements provide for severance payments equal to between six months and two years of such person's annual salary in the event a person's employment is terminated otherwise than for cause within one year following the occurrence of a change in control of Chiles or in the event that a person voluntarily terminates his employment within one year of a change in control of Chiles for "good reason," as defined in the agreement.
The Company is a defendant in certain other claims and litigation arising out of operations in the normal course of business. In the opinion of management, uninsured losses, if any, will not be material to the Company's financial position or results of operations.
In connection with the damage sustained on the Linn Richardson, the Company has recorded an estimated loss of $1,778,000 related to mobilization costs. See Note 9.
At December 31, 1995, the Company had certain noncancellable long-term operating leases, principally for office space and facilities, with various expiration dates. Future minimum rentals under sub-leases aggregate $1,630,000 for 1996, $1,292,000 for 1997, $1,169,000 for 1998, $1,148,000 for 1999, $866,000 for 2000, and $2,923,000 thereafter.
NOTE 13 --SUPPLEMENTAL LOSS PER SHARE DISCLOSURE
Assuming that all shares of $2.25 Preferred Stock had been converted on January 1, 1995 the supplemental primary net loss applicable to common shares per share for the year ended December 31, 1995 would have changed from $0.08 to $0.06. Supplemental fully diluted net loss applicable to common shares per share for the year ended December 31, 1995 is the same as supplemental primary net loss applicable to common shares per share since the effect of the conversion is anti-dilutive.

The purchase price would be $300,000,000 in cash plus 5,000,000 shares of Noble Drilling common stock. The Company currently plans to access the public securities markets to finance the cash portion of the purchase price.
Consummation of the acquisition is subject to customary due diligence, execution and delivery of an agreement of sale and purchase, financing being obtained by the Company, and satisfaction of customary closing conditions expected to be contained in the agreement of sale and purchase.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
The Board of Directors of the Company has appointed the accounting firm of Price Waterhouse LLP, which has audited the Company's financial statements since October 7, 1994, as independent accountants to audit the financial statements of the Company for the year ending December 31, 1996.
The accounting firm of Arthur Andersen LLP served as the independent accountant for the Company from August 1, 1988 until October 7, 1994. The decision to change accountants was recommended by the audit committee of the board of directors of Noble Drilling. Arthur Andersen LLP's report on the financial statements of the Company for the year ended December 31, 1993, contained no adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope, or accounting principles, or as to any other matter. During the year ended December 31, 1993, and the subsequent interim period preceding the dismissal, there were no disagreements with Arthur Andersen LLP on any matter of accounting principles or practices, financial statement disclosure, or accounting scope or procedure, which disagreements if not resolved to the satisfaction of Arthur Andersen LLP would have caused it to make reference thereto in its reports on the financial statements of the Company for such years. Additionally, no "reportable events" (as such term is defined under the applicable rules and regulations of the Securities and Exchange Commission) occurred during the year ended December 31, 1993, or the subsequent interim periods preceding Arthur Andersen LLP's dismissal.
