Our business is affected by laws and regulations relating to the energy industry and the environment and safety, including international conventions and treaties, and regional, national, state, and local laws and regulations. Our business also depends on demand for services from the oil and gas exploration and production industry, and, accordingly, we are directly affected by the adoption of laws and regulations that, for economic, environmental or other policy reasons, curtail, delay or impose additional compliance costs and obligations related to the exploration and development drilling for oil and gas. Offshore drilling in certain areas has been curtailed and, in certain cases, prohibited because of environmental or safety concerns. In addition, compliance with environmental and safety laws, regulations and standards, where applicable, may require us to make significant capital expenditures, such as the installation of costly equipment or implementation of operational changes, and may affect the resale values or useful lives of our rigs. We may incur additional costs in order to comply with other existing and future regulatory obligations or industry standards, including, but not limited to, costs relating to air emissions, including greenhouse gases, the management of ballast waters, hull cleaning, maintenance and inspection, development and implementation of emergency procedures and maintenance of insurance coverage or other financial assurance of our ability to address pollution incidents. In the last decade, U.S. federal agencies adopted enhanced governmental safety and environmental requirements applicable to our operations for drilling in the U.S. Gulf of Mexico. These requirements have caused increased compliance costs and may in the future increase the risk of environmental or safety enforcement cases and litigation and cause operators to have difficulties obtaining drilling permits in the U.S. Gulf of Mexico. The U.S. Bureau of Ocean Energy Management (the "BOEM") implemented changes regarding when oil, gas and sulfur lessees and certain other parties operating in the offshore Outer Continental Shelf must post additional bonds or other supplemental financial assurance, which could increase bonding requirements and operating expenditures for some of our customers, and as a result, increase price competition for our services.
The oil and gas industry has adopted equipment and operating standards, such as the American Petroleum Institute Standard 53, related to the installation and testing of well control equipment. A failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of our operations. Additionally, our customers may elect to voluntarily comply with any non-mandatory laws, regulations or other standards. Any such safety, environmental and other regulatory restrictions or standards, including voluntary customer compliance with respect thereto, could decrease, disrupt or delay operations, decrease demand for offshore drilling services, increase operating costs and compliance costs or penalties, increase out-of-service time, decrease dayrates, or reduce the area of operations for drilling rigs in the U.S. and non-U.S. offshore areas. Any such effects could have an adverse effect on our financial position, results of operations or cash flows.
To the extent new laws are enacted, existing laws are changed or other governmental or judicial actions are taken that prohibit or restrict offshore drilling or impose additional environmental protection and safety requirements that result in increased costs to the oil and gas industry, in general, or the offshore drilling industry, in particular, our business or prospects could be materially and adversely affected. The operation of our drilling rigs will require certain governmental approvals, some of which may involve public hearings and costly undertakings on our part. We may not obtain such approvals or such approvals may not be obtained in a timely manner. If we fail to timely secure the necessary governmental approvals or permits, our customers may have the right to terminate or seek to renegotiate their drilling contracts to our detriment. The amendment or modification of existing laws and regulations or the adoption of new laws and regulations curtailing or further regulating exploratory or development drilling or production of oil and gas and compliance with any such new or amended legislation or regulations could have an adverse effect on our business or on our financial position, results of operations or cash flows.
As a contract driller with operations in certain offshore areas, we may be liable for damages and costs incurred in connection with oil spills or disposal of wastes related to those operations, and we may also be subject to significant fines and other liabilities in connection with spills. For example, an oil spill could result in significant liability, including fines, penalties and criminal liability and remediation, restoration or compensation costs for environmental or natural resource damages, as well as third-party damages, to the extent that the contractual indemnification provisions in our drilling contracts are not enforceable or otherwise sufficient, or if our customers are unwilling or unable to contractually indemnify us against these risks. Additionally, we may not be able to obtain such indemnities in our future drilling contracts, and our customers may not have the financial capability to fulfill their contractual obligations to us. Also, these indemnities may be held to be unenforceable in certain jurisdictions, as a result of public policy or for other reasons. See "-Our business involves numerous operating hazards, and our insurance and indemnities from our customers may not be adequate to cover potential losses from our operations."
Environmental and safety laws and regulations protecting the environment have become increasingly stringent and may in some cases impose strict liability on facility or vessel owners or operators, rendering a person liable for environmental damage without regard to negligence. These laws and regulations may expose us to liability for the conduct of, or conditions caused by, others or for acts that were in compliance with all applicable laws at the time they were performed. The application of these requirements or the adoption of new requirements or measures could have an adverse effect on our financial position, results of operations or cash flows.
