Wiki Wiki Summary
Financial statement Financial statements (or financial reports) are formal records of the financial activities and position of a business, person, or other entity.\nRelevant financial information is presented in a structured manner and in a form which is easy to understand.
Financial ratio A financial ratio or accounting ratio is a relative magnitude of two selected numerical values taken from an enterprise's financial statements. Often used in accounting, there are many standard ratios used to try to evaluate the overall financial condition of a corporation or other organization.
Financial law Financial law is the law and regulation of the insurance, derivatives, commercial banking, capital markets and investment management sectors. Understanding Financial law is crucial to appreciating the creation and formation of banking and financial regulation, as well as the legal framework for finance generally.
Federal takeover of Fannie Mae and Freddie Mac In September 2008 the Federal Housing Finance Agency (FHFA) announced that it would take over the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac). Both government-sponsored enterprises, which finance home mortgages in the United States by issuing bonds, had become illiquid as the market for those bonds collapsed in the subprime mortgage crisis.
Regulation Regulation is the management of complex systems according to a set of rules and trends. In systems theory, these types of rules exist in various fields of biology and society, but the term has slightly different meanings according to context.
Mergers and acquisitions In corporate finance, mergers and acquisitions (M&A) are transactions in which the ownership of companies, other business organizations, or their operating units are transferred or consolidated with other entities. As an aspect of strategic management, M&A can allow enterprises to grow or downsize, and change the nature of their business or competitive position.

Arithmetic Arithmetic (from Ancient Greek ἀριθμός (arithmós) 'number', and τική [τέχνη] (tikḗ [tékhnē]) 'art, craft') is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today.
Bitwise operation In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
Special Activities Center The Special Activities Center (SAC) is a division of the Central Intelligence Agency responsible for covert operations and paramilitary operations. The unit was named Special Activities Division (SAD) prior to 2015.
Special operations Special operations (S.O.) are military activities conducted, according to NATO, by "specially designated, organized, selected, trained, and equipped forces using unconventional techniques and modes of employment". Special operations may include reconnaissance, unconventional warfare, and counter-terrorism actions, and are typically conducted by small groups of highly-trained personnel, emphasizing sufficiency, stealth, speed, and tactical coordination, commonly known as "special forces".
Operations management Operations management is an area of management concerned with designing and controlling the process of production and redesigning business operations in the production of goods or services. It involves the responsibility of ensuring that business operations are efficient in terms of using as few resources as needed and effective in meeting customer requirements.
Operations research Operations research (British English: operational research), often shortened to the initialism OR, is a discipline that deals with the development and application of advanced analytical methods to improve decision-making. It is sometimes considered to be a subfield of mathematical sciences.
Emergency operations center An emergency operations center (EOC) is a central command and control facility responsible for carrying out the principles of emergency preparedness and emergency management, or disaster management functions at a strategic level during an emergency, and ensuring the continuity of operation of a company, political subdivision or other organization.\nAn EOC is responsible for strategic direction and operational decisions and does not normally directly control field assets, instead leaving tactical decisions to lower commands.
Operation (mathematics) In mathematics, an operation is a function which takes zero or more input values (called operands) to a well-defined output value. The number of operands (also known as arguments) is the arity of the operation.
Nuclear magnetic resonance spectroscopy Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei. The sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with sensitive radio receivers.

Integration testing Integration testing (sometimes called integration and testing, abbreviated I&T) is the phase in software testing in which individual software modules are combined and tested as a group. Integration testing is conducted to evaluate the compliance of a system or component with specified functional requirements.
Integrator An integrator in measurement and control applications is an element whose output signal is the time integral of its input signal. It accumulates the input quantity over a defined time to produce a representative output.
Contour integration In the mathematical field of complex analysis, contour integration is a method of evaluating certain integrals along paths in the complex plane.Contour integration is closely related to the calculus of residues, a method of complex analysis.\nOne use for contour integrals is the evaluation of integrals along the real line that are not readily found by using only real variable methods.Contour integration methods include:\n\ndirect integration of a complex-valued function along a curve in the complex plane (a contour);\napplication of the Cauchy integral formula; and\napplication of the residue theorem.One method can be used, or a combination of these methods, or various limiting processes, for the purpose of finding these integrals or sums.
Continuous integration In software engineering, continuous integration (CI) is the practice of merging all developers' working copies to a shared mainline several times a day. Grady Booch first proposed the term CI in his 1991 method, although he did not advocate integrating several times a day.
European integration European integration is the process of industrial, economic, political, legal, social and cultural integration of states wholly or partially in Europe or nearby. European integration has primarily come about through the European Union and its policies.
Integration by parts In calculus, and more generally in mathematical analysis, integration by parts or partial integration is a process that finds the integral of a product of functions in terms of the integral of the product of their derivative and antiderivative. It is frequently used to transform the antiderivative of a product of functions into an antiderivative for which a solution can be more easily found.
Risk Factors
AMERICAN TOWER CORP /MA/ ITEM 1A RISK FACTORS Decrease in demand for tower space would materially and adversely affect our operating results and we cannot control that demand
Many of the factors affecting the demand for wireless communications tower space, and to a lesser extent our network development services business, could adversely affect our operating results
Those factors include: • a decrease in consumer demand for wireless services due to general economic conditions or other factors; • the financial condition of wireless service providers; • the ability and willingness of wireless service providers to maintain or increase capital expenditures; • the growth rate of wireless communications or of a particular wireless segment; • governmental licensing of spectrum; • mergers or consolidations among wireless service providers; • increased use of network sharing, roaming or resale arrangements by wireless service providers; • delays or changes in the deployment of 3G or other technologies; • zoning, environmental, health and other government regulations; and • technological changes
The demand for broadcast antenna space is dependent on the needs of television and radio broadcasters
Among other things, technological advances, including the development of satellite-delivered radio, may reduce the need for tower-based broadcast transmission
We could also be affected adversely should the development of digital television be further delayed or impaired, or if demand for it were less than anticipated because of delays, disappointing technical performance or cost to the consumer
If our wireless service provider customers consolidate or merge with each other to a significant degree, our growth, revenue and ability to generate positive cash flows could be adversely affected
Significant consolidation among our wireless service provider customers may result in reduced capital expenditures in the aggregate because the existing networks of many wireless carriers overlap, as do their expansion plans
For example, as a result of the recently completed mergers between Cingular Wireless and AT&T Wireless and between Sprint PCS and Nextel, both Cingular Wireless and Sprint Nextel are exploring ways of rationalizing portions of their combined, yet technologically separate, wireless networks
Certain parts of their merged networks may be deemed to be duplicative and these customers may attempt to eliminate these duplications
Our future results may be negatively impacted if a significant number of these contracts are eliminated from our ongoing contractual revenues
Similar consequences might occur if wireless service providers engage in extensive sharing, roaming or resale arrangements as an alternative to leasing our antenna space
12 ______________________________________________________________________ [67]Table of Contents In January 2003, the FCC eliminated its spectrum cap, which prohibited wireless carriers from owning more than 45 MHz of spectrum in any given geographical area
The FCC has also eliminated the cross-interest rule for metropolitan areas, which limited an entity’s ability to own interests in multiple cellular licenses in an overlapping geographical service area
Also, in May 2003, the FCC adopted new rules authorizing wireless radio services holding exclusive licenses to freely lease unused spectrum
These regulatory changes may encourage consolidation among wireless carriers, which, if it resulted in a loss of one or more of our major customers, could materially decrease our revenues and cash flows
Substantial leverage and debt service obligations may adversely affect us
We have a substantial amount of indebtedness
As of December 31, 2005, we had approximately dlra3dtta6 billion of consolidated debt
Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay when due the principal of, interest on, or other amounts due with respect to our indebtedness
As of December 31, 2005, approximately 41prca of our outstanding indebtedness bore interest at floating rates (approximately 21prca, after giving effect to the interest rate swap agreements used to manage exposure to variable rate interest obligations on our credit facilities)
As a result, our interest payment obligations on such indebtedness will increase if interest rates increase
Subject to certain restrictions under our existing indebtedness, we may also obtain additional long-term debt and working capital lines of credit to meet future financing needs
Our substantial leverage could have significant negative consequences on our financial condition and results of operations, including: • impairing our ability to meet one or more of the financial ratios contained in our debt agreements or to generate cash sufficient to pay interest or principal, which events could result in an acceleration of some or all of our outstanding debt as a result of cross-default provisions; • increasing our vulnerability to general adverse economic and industry conditions; • limiting our ability to obtain additional debt or equity financing; • requiring the dedication of a substantial portion of our cash flow from operations to service our debt, thereby reducing the amount of our cash flow available for other purposes, including capital expenditures; • requiring us to sell debt or equity securities or to sell some of our core assets, possibly on unfavorable terms, to meet payment obligations; • limiting our flexibility in planning for, or reacting to, changes in our business and the industries in which we compete; and • placing us at a possible competitive disadvantage with less leveraged competitors and competitors that may have better access to capital resources
Restrictive covenants in our credit facilities and indentures could adversely affect our business by limiting flexibility
Our credit facilities and the indentures governing the terms of our debt securities contain restrictive covenants
Our credit facilities also contain requirements that the borrowers under each facility comply with certain leverage and other financial tests
These covenants and requirements limit our ability to take various actions, including incurring additional debt, guaranteeing indebtedness, engaging in various types of transactions, including mergers and sales of assets, and paying dividends and making distributions or other restricted payments
These covenants could place us at a disadvantage compared to some of our competitors which may have fewer restrictive covenants and may not be required to operate under these restrictions
Further, these covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisition or other opportunities
13 ______________________________________________________________________ [68]Table of Contents Due to the long-term expectations of revenue from tenant leases, the tower industry is sensitive to the creditworthiness of its tenants
Due to the long-term nature of our tenant leases, we, like others in the tower industry, are dependent on the continued financial strength of our tenants
Many wireless service providers operate with substantial leverage
During the past few years, several of our customers have filed for bankruptcy, although to date these bankruptcies have not had a material adverse effect on our business or revenues
If one or more of our major customers experience financial difficulties, it could result in uncollectible accounts receivable and our loss of significant customers and anticipated lease revenues
Our foreign operations are subject to economic, political and other risks that could adversely affect our revenues or financial position
Our business operations in Mexico and Brazil, and any other possible foreign operations in the future, could result in adverse financial consequences and operational problems not experienced in the United States
For the year ended December 31, 2005, approximately 13prca of our consolidated revenues were generated by our international operations (assuming our merger with SpectraSite, Inc
We anticipate that our revenues from our international operations may grow in the future
Accordingly, our business is subject to risks associated with doing business internationally, including: • changes in a specific country’s or region’s political or economic conditions; • laws and regulations that restrict repatriation of earnings or other funds; • difficulty in recruiting trained personnel; and • language and cultural differences
In addition, we face risks associated with changes in foreign currency exchange rates
While most of the contracts for our international operations are denominated in the US dollar, others are denominated in the Mexican Peso or the Brazilian Real
We have not historically engaged in significant hedging activities relating to our non-US dollar operations, and we may suffer future losses as a result of adverse changes in currency exchange rates
A substantial portion of our revenue is derived from a small number of customers
A substantial portion of our total operating revenues is derived from a small number of customers
For the year ended December 31, 2005, after giving effect to our merger with SpectraSite, Inc
(assuming the merger occurred on January 1, 2005): • Five customers accounted for approximately 59prca of our revenues; • Cingular Wireless accounted for approximately 19prca of our revenues; • Sprint Nextel (assuming the merger of Sprint PCS and Nextel occurred on January 1, 2005) accounted for approximately 17prca of our revenues (approximately 22prca including Sprint Nextel partners and affiliates); and • Verizon Wireless accounted for approximately 10prca of our revenues
Our largest international customer is Iusacell Celular, which accounted for approximately 3prca of our total revenues for the year ended December 31, 2005 (assuming our merger with SpectraSite, Inc
Iusacell is an affiliate of TV Azteca, which owns a minority interest in Unefon, which is our second largest customer in Mexico and accounted for approximately 2prca of our total revenues for the year ended December 31, 2005 (assuming our merger with SpectraSite, Inc
In addition, we received dlra14dtta2 million in interest income, net, from TV Azteca for the year ended December 31, 2005
14 ______________________________________________________________________ [69]Table of Contents If any of these customers were unwilling or unable to perform their obligations under our agreements with them, our revenues, results of operations, and financial condition could be adversely affected
In the ordinary course of our business, we also sometimes experience disputes with our customers, generally regarding the interpretation of terms in our agreements
Although historically we have resolved these disputes in a manner that did not have a material adverse effect on our company or our customer relationships, in the future these disputes could lead to a termination of our agreements with customers or a material modification of the terms of those agreements, either of which could have a material adverse effect on our business, results of operations and financial condition
If we are forced to resolve any of these disputes through litigation, our relationship with the applicable customer could be terminated or damaged, which could lead to decreased revenues or increased costs, resulting in a corresponding adverse effect on our business, results of operations and financial condition
Status of Iusacell Celular’s financial restructuring exposes us to certain risks and uncertainties
Iusacell Celular is our largest customer in Mexico and accounted for approximately 3prca of our total revenues for the year ended December 31, 2005 (assuming our merger with SpectraSite, Inc
Iusacell has been in default under certain of its debt obligations and involved in litigation with certain of its creditors
While Iusacell reported in January 2006 that it has reached an agreement in principle with its creditors to restructure its debt obligations, if the restructuring is not completed, Iusacell files for bankruptcy, or the creditor litigation has an adverse impact on Iusacell’s overall liquidity, it could interfere with Iusacell’s ability to meet its operating obligations, including rental payments under our leases with them
We may not realize the intended benefits of our merger with SpectraSite, Inc
if we are unable to integrate SpectraSite’s operations, wireless communications tower portfolio, customers and personnel in a timely and efficient manner, which could adversely affect our business and the value of our Class A common stock
Achieving the benefits of our merger with SpectraSite, Inc
depends in part on the integration of our operations, wireless communications tower portfolios and personnel with those of SpectraSite in a timely and efficient manner and the ability of the combined company to realize the anticipated synergies from this integration
Integration may be difficult and unpredictable for many reasons, including, among others, the size of SpectraSite’s wireless communications tower portfolio and because SpectraSite’s and our internal systems and processes were developed without regard to such integration
Our successful integration with SpectraSite requires coordination of different personnel, which may be difficult and unpredictable because of possible cultural conflicts and differences in policies, procedures and operations between the companies and the different geographical locations of the companies
Our successful integration also requires attention to and maintenance of our business relationships with current customers, which if compromised, would result in disruptions to our business
If we cannot successfully integrate SpectraSite’s operations, wireless communications tower portfolio, customers and personnel, we may not realize the expected benefits of the merger, which could adversely affect the combined company’s business and could adversely affect the value of our Class A common stock
In addition, the integration of our business with SpectraSite may place a significant burden on management and its internal resources
The diversion of management’s attention from ongoing business concerns and any difficulties encountered in the transition and integration process could harm our business and financial results of the combined company and the value of our Class A common stock
We expect to incur substantial expenses related to the integration of SpectraSite
We expect to incur substantial expenses in connection with the integration of the business, policies, procedures, operations and systems of SpectraSite
While we have integrated many of the companies’ systems and administrative activities to date, we do not expect to complete our integration efforts until the second quarter of 2006
If we fail to meet the challenges involved in integrating the companies’ business and operations, or we are unable to do so on a timely basis, it could result in substantial additional expenses and harm to the combined company
These expenses could, particularly in the near term, exceed the savings that we expect to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the integration of the businesses
15 ______________________________________________________________________ [70]Table of Contents New technologies could make our tower leasing business less desirable to potential tenants and result in decreasing revenues
The development and implementation of new technologies designed to enhance the efficiency of wireless networks could reduce the use and need for tower-based wireless services transmission and reception and have the effect of decreasing demand for tower space
Examples of such technologies include technologies that enhance spectral capacity, such as lower-rate vocoders, which can increase the capacity at existing sites and reduce the number of additional sites a given carrier needs to serve any given subscriber base
In addition, the emergence of new technologies could reduce the need for tower-based broadcast services transmission and reception
For example, the growth in delivery of video services by direct broadcast satellites could adversely affect demand for our antenna space
The development and implementation of any of these and similar technologies to any significant degree could have an adverse effect on our operations
We could have liability under environmental laws
Our operations, like those of other companies engaged in similar businesses, are subject to the requirements of various federal, state and local and foreign environmental and occupational safety and health laws and regulations, including those relating to the management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances, materials and wastes
As owner, lessee or operator of many thousands of real estate sites underlying our towers, we may be liable for substantial costs of remediating soil and groundwater contaminated by hazardous materials, without regard to whether we, as the owner, lessee or operator, knew of or were responsible for the contamination
Many of these laws and regulations contain information reporting and record keeping requirements
We cannot assure you that we are at all times in complete compliance with all environmental requirements
We may be subject to potentially significant fines or penalties if we fail to comply with any of these requirements
The current cost of complying with these laws (including amounts we expect to pay the EPA pursuant to the Facilities Audit Agreement) is not material to our financial condition or results of operations
However, the requirements of these laws and regulations are complex, change frequently, and could become more stringent in the future
It is possible that these requirements will change or that liabilities will arise in the future in a manner that could have a material adverse effect on our business, financial condition and results of operations
Our business is subject to government regulations and changes in current or future laws or regulations could restrict our ability to operate our business as we currently do
We are subject to federal, state, local and foreign regulation of our business, including regulation by the FAA, the FCC, the EPA and OSHA Both the FCC and the FAA regulate towers used for wireless communications and radio and television antennas and the FCC separately regulates transmitting devices operating on towers
Similar regulations exist in Mexico, Brazil and other foreign countries regarding wireless communications and the operation of communications towers
Local zoning authorities and community organizations are often opposed to construction in their communities and these regulations can delay, prevent or increase the cost of new tower construction, modifications, additions of new antennas to a site, or site upgrades, thereby limiting our ability to respond to customer demands and requirements
Existing regulatory policies may adversely affect the associated timing or cost of such projects and additional regulations may be adopted which increase delays or result in additional costs to us, or that prevent such projects in certain locations
These factors could adversely affect our operations
Increasing competition in the tower industry may create pricing pressures that may adversely affect us
Our industry is highly competitive, and our customers have numerous alternatives for leasing antenna space
Some of our competitors, such as national wireless carriers that allow collocation on their towers, are larger and have greater financial resources than we do, while other competitors are in weak financial condition or may have lower return on investment criteria than we do
Competitive pricing pressures for tenants on towers from these competitors could adversely affect our lease rates and services income
16 ______________________________________________________________________ [71]Table of Contents In addition, if we lose customers due to pricing, we may not be able to find new customers, leading to an accompanying adverse effect on our profitability
Increasing competition could also make the acquisition of high quality tower assets more costly
Our competition includes: • national and regional tower companies; • wireless carriers that own towers and lease antenna space to other carriers; • site development companies that purchase antenna space on existing towers for wireless carriers and manage new tower construction; and • alternative site structures (eg, building rooftops, billboards and utility poles)
If we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results
Our real property interests relating to our towers consist primarily of leasehold and sub-leasehold interests, fee interests, easements, licenses and rights-of-way
A loss of these interests may interfere with our ability to operate our towers and generate revenues
For various reasons, we may not always have the ability to access, analyze and verify all information regarding titles and other issues prior to completing an acquisition of communications sites
Further, we may not be able to renew ground leases on commercially viable terms
Approximately 85prca of the owned communications sites in our portfolio as of December 31, 2005 are located on leased land
Approximately 85prca of these sites are on land where our property interests in such land have a final expiration date of 2015 and beyond
Our inability to protect our rights to the land under our towers may have a material adverse affect on us
If we are unable or choose not to exercise our rights to purchase towers that are subject to lease and sublease agreements at the end of the applicable period, our cash flows derived from such towers would be eliminated
Our communications site portfolio includes towers that we operate pursuant to lease and sublease agreements that include a purchase option at the end of each lease period
If we are unable or choose not to exercise our rights to purchase towers under these agreements at the end of the applicable period, our cash flows derived from such towers would be eliminated
For example, our SpectraSite subsidiary has entered into lease or sublease agreements with affiliates of SBC Communications (SBC) with respect to approximately 2cmam500 towers pursuant to which SpectraSite has the option to purchase the sites upon the expiration of the lease or sublease beginning in 2013
The aggregate purchase option price for the SBC towers was approximately dlra282dtta4 million as of December 31, 2005, and will accrete at a rate of 10prca per year to the applicable expiration of the lease or sublease of a site
In addition, we have entered into a similar agreement with ALLTEL with respect to approximately 1cmam776 towers, for which we have an option to purchase the sites upon the expiration of the lease or sublease beginning in 2016
The aggregate purchase option price for the ALLTEL towers was approximately dlra56dtta2 million as of December 31, 2005, and will accrete at a rate of 3prca per annum
We may not have the required available capital to exercise our right to purchase these or other lease or subleased towers at the end of the applicable period
Even if we do have available capital, we may choose not to exercise our right to purchase such towers for business or other reasons
In the event that we decide to exercise these purchase rights, the benefits of the acquisitions of such towers may not exceed the associated acquisition, compliance and integration costs, and our financial results could be adversely affected
Our towers may be affected by natural disasters and other unforeseen damage for which our insurance may not provide adequate coverage
Our towers are subject to risks associated with natural disasters, such as ice and wind storms, tornadoes, floods, hurricanes and earthquakes, as well as other unforeseen damage
Any damage or destruction to our towers 17 ______________________________________________________________________ [72]Table of Contents as a result of these or other risks would impact our ability to provide services to our customers and could impact our results of operation and financial condition
For example, as a result of the severe hurricane activity in 2005, approximately 25 of our broadcast and wireless communications sites in the southeastern United States and Mexico suffered material damage and many more suffered lesser damage
While we maintain insurance, including business interruption insurance, for our towers against these risks, we may not have adequate insurance to cover the associated costs of repair or reconstruction
Further, such business interruption insurance may not adequately cover all of our lost revenues, including potential revenues from new tenants that could have been added to our towers but for the damage
If we are unable to provide services to our customers as a result of damages to our towers, it could lead to customer loss, resulting in a corresponding adverse effect on our business, results of operations and financial condition
Our costs could increase and our revenues could decrease due to perceived health risks from radio emissions, especially if these perceived risks are substantiated
Public perception of possible health risks associated with cellular and other wireless communications media could slow the growth of wireless companies, which could in turn slow our growth
In particular, negative public perception of, and regulations regarding, these perceived health risks could slow the market acceptance of wireless communications services and increase opposition to the development and expansion of tower sites
The potential connection between radio frequency emissions and certain negative health effects has been the subject of substantial study by the scientific community in recent years, and numerous health-related lawsuits have been filed against wireless carriers and wireless device manufacturers
If a scientific study or court decision resulted in a finding that radio frequency emissions posed health risks to consumers, it could negatively impact the market for wireless services, as well as our wireless carrier customers, which would adversely effect our operations, costs and revenues
We do not maintain any significant insurance with respect to these matters
The bankruptcy proceeding of our Verestar subsidiary exposes us to risks and uncertainties
Our wholly owned subsidiary, Verestar, Inc, filed for protection under Chapter 11 of the federal bankruptcy laws in December 2003
If Verestar fails to honor certain of its contractual obligations because of its bankruptcy filing or otherwise, claims may be made against us for breaches by Verestar of those contracts as to which we are primarily or secondarily liable as a guarantor (which we do not expect to exceed dlra3dtta2 million)
In addition, in July 2005, the Official Committee of Unsecured Creditors appointed in the bankruptcy proceeding (the Committee) filed a complaint in the US District Court for the Southern District of New York against us and certain of our and Verestar’s current and former officers, directors and advisors, and also filed a complaint in the Bankruptcy Court against us
(The case initially filed in the District Court has since been transferred to the Bankruptcy Court, and both cases are now pending as a single, consolidated case before the same Bankruptcy judge
) Pursuant to the complaints, the Committee is seeking unspecified compensatory damages of not less than dlra150dtta0 million, punitive damages and various costs and fees
The outcome of this complex litigation cannot be predicted by us with certainty, is dependent upon many factors beyond our control, and could take several years to resolve
If any such claims are successful, however, they could have a material adverse impact on our financial position and results of operations
For more information regarding the Verestar bankruptcy and
