Wiki Wiki Summary
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.
Operation Mincemeat Operation Mincemeat was a successful British deception operation of the Second World War to disguise the 1943 Allied invasion of Sicily. Two members of British intelligence obtained the body of Glyndwr Michael, a tramp who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as the fictitious Captain (Acting Major) William Martin.
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.

Risk Factors
NII HOLDINGS INC Item 1A Risk Factors Investors should be aware of various risks, including the risks described below
Our business, financial condition or results of operations could be materially adversely affected by any of these risks
The trading price of our common stock could decline due to any of these risks, and investors may lose all or part of any investment
Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and included elsewhere
Please note that additional risks not presently known to us or that we currently deem immaterial may also impair our business and operations
If we are not able to compete effectively in the highly competitive wireless communications industry, our future growth and operating results will suffer
Our success will depend on the ability of our operating companies to compete effectively with other telecommunications services providers, including wireline companies and other wireless telecommunications companies, in the markets in which they operate
Some of our competitors are financially stronger than we are, which may limit our ability to compete based on price
Because of their resources, and in some cases ownership by larger companies, some of our competitors may be able to offer services to customers at prices that are below the prices that our operating companies can offer for comparable services
If we cannot compete effectively based on the price of our service offerings, our results of operations may be adversely affected
For example, many of our competitors are well-established companies that have: • substantially greater financial and marketing resources; • larger customer bases; • better name recognition; • bundled service offerings; • larger spectrum positions; and • larger coverage areas than those of our operating companies
In addition, we anticipate that our operating companies will continue to face market pressure to reduce the prices charged for their products and services because of increased competition in our markets
Our operating companies may face disadvantages when competing against formerly government-owned incumbent wireline operators or wireless operators affiliated with them
In some markets, our operating companies may not be able to compete effectively against a formerly government-owned monopoly telecommunications operator, which today enjoys a near monopoly on the provision of wireline telecommunications services and may have a wireless affiliate or may be controlled by shareholders who also control a wireless operator
Our operating companies may be at a competitive disadvantage in these markets because formerly government-owned incumbents or affiliated competitors may have: • close ties with national regulatory authorities; • control over connections to local telephone lines; or • the ability to subsidize competitive services with revenues generated from services they provide on a monopoly or near-monopoly basis
25 _________________________________________________________________ Our operating companies may encounter obstacles and setbacks if local governments adopt policies favoring these competitors or otherwise afford them preferential treatment
As a result, our operating companies may be at a competitive disadvantage to incumbent providers, particularly as our operating companies seek to offer new telecommunications services
Our coverage is not as extensive as those of other wireless service providers in our markets, which may limit our ability to attract and retain customers
Since our digital mobile networks do not offer nationwide coverage in the countries in which we operate and our technology limits our potential roaming partners, we may not be able to compete effectively with cellular and personal communications services providers in our markets
Many of the cellular and personal communications services providers in our markets have networks with substantially more extensive areas of service
Additionally, many of these providers have entered into roaming agreements with each other, which permit these providers to offer coverage to their subscribers in each other’s markets
The iDEN technology that we deploy is not compatible with other wireless technologies such as digital cellular or personal communications services technologies or with other iDEN networks not operating in the 800 MHz spectrum
As a result, with the exception of GSM 900 MHz systems, we cannot enter into roaming agreements with the operators of these other networks
Although the i2000 digital phone that we sell is compatible with both iDEN 800 MHz and GSM 900 MHz systems, our customers will not be able to roam on other iDEN 800 MHz or GSM 900 MHz systems where we do not have a roaming agreement
As a result, we will not be able to provide coverage to our subscribers outside of our currently operating digital markets until: • other operators deploy iDEN 800 MHz or GSM 900 MHz technology in markets outside of our coverage areas and we enter into roaming agreements with those operators; or • handsets that can be used on both iDEN 800 MHz and non-GSM 900 MHz wireless communications networks become available and we enter into roaming agreements with the operators of those networks
If we do not keep pace with rapid technological changes, we may not be able to attract and retain customers
The wireless telecommunications industry is experiencing significant technological change
Future technological advancements may enable other wireless technologies to equal or exceed our current level of service and render iDEN technology obsolete
If Motorola, the sole supplier of iDEN technology, is unable or unwilling to upgrade or improve iDEN technology or develop other technology to meet future advances in competing technologies on a timely basis, or at an acceptable cost, we will be less able to compete effectively and could lose customers to our competitors
In addition, competition among the differing wireless technologies could: • segment the user markets, which could reduce demand for our technology; and • reduce the resources devoted by third-party suppliers, including Motorola, which supplies all of our current digital mobile technology, to developing or improving the technology for our systems
If our wireless communications technology does not perform in a manner that meets customer expectations, we will be unable to attract and retain customers
Customer acceptance of the services we offer is and will continue to be affected by technology-based differences and by the operational performance and reliability of our digital mobile networks
We may have difficulty attracting and retaining customers if we are unable to address and resolve satisfactorily performance or other transmission quality issues as they arise or if these issues: • limit our ability to expand our network coverage or capacity as currently planned; or • place us at a competitive disadvantage to other wireless service providers in our markets
26 _________________________________________________________________ Our equipment is more expensive than that of some competitors, which may affect our ability to establish and maintain a significant subscriber base
We currently market multi-function digital handsets, and Motorola is the sole supplier of all our handsets
The higher cost of our equipment may make it more difficult for us to attract customers
In addition, the higher cost of our handsets requires us to absorb a comparatively larger part of the cost of offering handsets to new and existing customers
These higher costs of handsets place us at a competitive disadvantage and may reduce our growth and profitability
We may lose a competitive advantage because our competitors are providing two-way radio dispatch and other services
Several of our competitors have introduced Push-To-Talk over Cellular service, which is a walkie-talkie type of service similar to our Direct Connect service
In addition, we do not have short messaging system (SMS) interoperability agreements in all our markets
Consequently, our competitive advantage may be impaired
Because we rely on one supplier to implement our digital mobile networks, any failure of that supplier to perform could adversely affect our operations
Motorola is currently our sole source for most of the digital network equipment and all of the handsets used throughout our markets
In addition, iDEN technology is a proprietary technology of Motorola, meaning that there are no other suppliers of this technology, and it is the only widespread, commercially available digital technology that operates on non-contiguous spectrum
Much of the spectrum that our operating companies hold in each of the markets we serve is non-contiguous
The non-contiguous nature of our spectrum may make it more difficult for us to migrate to a new technology if we choose to do so
Additionally, if Motorola fails to deliver system infrastructure equipment and handsets or enhancements on a timely, cost-effective basis, we may not be able to adequately service our existing customers or add new customers
Nextel Communications, a subsidiary of SprintNextel Corporation, is the largest customer of Motorola with respect to iDEN technology and provides significant support with respect to new product development
Nextel Communications and Sprint merged on August 12, 2005, and as a result, Nextel Communications became a subsidiary of Sprint Nextel
The new combined company had previously announced plans to migrate Nextel’s push-to-talk services to a next generation CDMA network platform
Nextel Communications had also announced an agreement with Motorola for a three-year extension of its iDEN infrastructure supply agreement and handset purchase agreement, with certain modifications
Any decrease by Nextel Communications in its use of iDEN technology could significantly increase our costs for equipment and new developments and could impact Motorola’s decision to continue to support iDEN technology
In the event Motorola determines not to continue manufacturing, supporting or enhancing our iDEN based infrastructure and handsets, because Nextel Communications decreases its use of iDEN technology or otherwise, we may be materially adversely affected
We expect to continue to rely principally on Motorola for the manufacture of a substantial portion of the equipment necessary to construct, enhance and maintain our digital mobile networks and for the manufacture of handsets for the next several years
We operate exclusively in foreign markets, and our assets, customers and cash flows are concentrated in Latin America, which presents risks to our operating and financing plans
We face political and economic risks in our markets, which may limit our ability to implement our strategy and our financial flexibility and may disrupt our operations
The countries in which we operate are considered to be emerging markets
Although political, economic and social conditions differ in each country in which we currently operate, political and economic developments in one country may affect our business as a whole, including our access to international capital markets
Negative developments or unstable conditions in the countries in which we operate or in other emerging market countries could have a material adverse effect on our financial condition and results of operations
In Peru, for example, there was significant terrorist activity in the 1980s and the early 1990s
During that time, anti-government groups escalated violence against the government, the private sector and 27 _________________________________________________________________ Peruvian residents
Incidents of terrorist activity continue to occur
Similar outbreaks of terrorism or political violence have occurred in Mexico and other countries in which we operate
In addition, in 2001, after prolonged periods of recession followed by political instability, the Argentine government announced it would not service its public debt
In order to address the worsening economic and social crisis, the Argentine government abandoned its decade-old fixed Argentine peso-US dollar exchange rate, allowing the currency to float to market levels
During 2006, there will be presidential elections held in three of our major markets
We are unable to predict the impact that presidential or other contested local or national elections and the associated transfer of power from incumbent officials or political parties to elected victors, may have on the local economy or the growth and development of the local telecommunications industry
Changes in leadership or in the ruling party in the countries in which we operate may affect the economic programs developed under the prior administration, which in turn, may adversely affect the economies in the countries in which we operate and our business operations and prospects in these countries
Due to our significant operations in Argentina and Brazil, our business is particularly exposed to risks associated with adverse economic and political conditions in those countries
In recent years, both Argentina and Brazil have been negatively affected by volatile economic and political conditions
These volatile conditions pose risks for our business
In particular, the volatility of the Argentine peso and the Brazilian real has affected our recent financial results
The depreciation of the currencies in Argentina and Brazil in 2002 had a material negative impact on our financial results
After a prolonged period of recession, followed by political instability, Argentina announced in December 2001 that it would impose tight restrictions on bank accounts, would not service its public sector debt and suspended foreign currency trading
In January 2002, the Argentine government abandoned its decade-old fixed Argentine peso-US dollar exchange rate
The resulting depreciation of the Argentine peso against the US dollar during the 2002 calendar year was 66prca
A depreciation of the Argentine peso generally affects our consolidated financial statements by generating a foreign currency transaction loss on US dollar-denominated debt
Until October 31, 2002, the liabilities of our Argentine operating company included US dollar-denominated secured debt, for which we recognized foreign currency transaction losses of dlra137dtta5 million for the ten months ended October 31, 2002
A depreciation of the Argentine peso also affects our consolidated financial statements by reducing the translation rate of all Argentine peso-denominated balances
To the extent net income is generated by our Argentine operating company, the amount would be reduced by a depreciation of the Argentine peso
The Brazilian economy has been characterized by frequent and occasionally drastic intervention by the Brazilian government and by volatile economic cycles
The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the course of Brazil’s economy
In early 1999, the Brazilian government allowed the Brazilian real to float freely, resulting in a 32prca depreciation against the US dollar that year
In 2002, the Brazilian real depreciated against the US dollar by 18prca
In addition, economic and market conditions in other emerging markets can influence the perception of Brazil’s economic and political situation
We are subject to fluctuations in currency exchange rates and limitations on the expatriation or conversion of currencies, which may result in significant financial charges, increased costs of operations or decreased demand for our products and services
Nearly all of our revenues are earned in non-US currencies, while a significant portion of our capital and operating expenditures, including imported network equipment and handsets, and substantially all of our outstanding debt, is priced in US dollars
In addition, we report our results of operations in US dollars
Accordingly, fluctuations in exchange rates relative to the US dollar could have a material adverse effect on our earnings or assets
For example, the 1999 and 2002 currency devaluations in Brazil resulted in significant charges against our earnings in 1999 and 2002 and negative adjustments to the carrying value of our assets in Brazil
The economic upheaval in Argentina in 2002 led to the unpegging of the Argentine peso to the US dollar exchange rate and the subsequent significant devaluation of the Argentine peso, which resulted in 28 _________________________________________________________________ charges against our earnings in 2002 and negative adjustments to the carrying values of our assets in Argentina
Any depreciation of local currencies in the countries in which our operating companies conduct business may result in increased costs to us for imported equipment and may, at the same time, decrease demand for our products and services in the affected markets
If our operating companies distribute dividends in local currencies in the future, the amount of cash we receive will also be affected by fluctuations in exchange rates and currency devaluations
In addition, some of the countries in which we have operations do or may restrict the expatriation or conversion of currency
Our operating companies are subject to fluctuating economic conditions in the local markets in which they operate, which could hurt their performance
Our operations depend on the economies of the markets in which our operating companies conduct business
These markets are in countries with economies in various stages of development or structural reform, some of which are subject to rapid fluctuations in terms of commodity prices, local consumer prices, employment levels, gross domestic product, interest rates and inflation rates
If these fluctuations have an effect on the ability of customers to pay for our products and services, our business may be adversely affected
As a result, our operating companies may experience lower demand for their products and services and a decline in the growth of their customer base and in revenues
Some of our operating companies conduct business in countries where the rate of inflation is significantly higher than in the United States
Any significant increase in the rate of inflation in any of these countries may not be completely or partially offset by corresponding price increases implemented by our operating companies, even over the long term
Our operating companies are subject to local laws and customs in the countries in which they operate, which could impact our financial results
Our operations are subject to local laws and customs in the countries in which we operate, which may differ from those in the US We could become subject to legal penalties in foreign countries if we do not comply with local laws and regulations, which may be substantially different from those in the United States
In some foreign countries, particularly in those with developing economies, persons may engage in business practices that are prohibited by United States regulations applicable to us such as the Foreign Corrupt Practices Act
Although we implement policies and procedures designed to ensure compliance with these laws, there can be no assurance that all of our employees, consultants, contractors and agents will not take actions in violations of our policies
Any such violation, even if prohibited by our policies, could have a material adverse effect on our business
We pay significant import duties on our network equipment and handsets, and any increases could impact our financial results
Our operations are highly dependent upon the successful and cost-efficient importation of network equipment and handsets from North America and, to a lesser extent, from Europe and Asia
Any significant increase in import duties in the future could significantly increase our costs
To the extent we cannot pass these costs on to our customers, our financial results will be negatively impacted
In the countries in which our operating companies conduct business, network equipment and handsets may be subject to significant import duties and other taxes
We are subject to foreign taxes in the countries in which we operate, which may reduce amounts we receive from our operating companies or may increase our tax costs
Many of the foreign countries in which we operate have increasingly turned to new taxes, as well as aggressive interpretations of current taxes, as a method of increasing revenue
For instance, Brazil has a tax on financial transactions, certain provinces in Argentina adopted higher tax rates on telecommunications services in 2001, and Argentina adopted a federal universal services tax in 2001
The provisions of new tax laws may attempt to prohibit us from passing these taxes on to our customers
These taxes may reduce the amount of earnings that we can generate from our services
29 _________________________________________________________________ Distributions of earnings and other payments, including interest, received from our operating companies may be subject to withholding taxes imposed by some countries in which these entities operate
In general, a US corporation may claim a foreign tax credit against its Federal income tax expense for foreign withholding taxes and, under certain circumstances, for its share of foreign income taxes paid directly by foreign corporate entities in which the company owns 10prca or more of the voting stock
Our ability to claim foreign tax credits is, however, subject to numerous limitations, and we may incur incremental tax costs as a result of these limitations or because we do not have US Federal taxable income
We may also be required to include in our income for US Federal income tax purposes our proportionate share of specified earnings of our foreign corporate subsidiaries that are classified as controlled foreign corporations, without regard to whether distributions have been actually received from these subsidiaries
Nextel Brazil has received tax assessment notices from state and federal Brazilian tax authorities asserting deficiencies in tax payments related primarily to value added taxes, import duties and matters surrounding the definition and classification of equipment and services
Nextel Brazil has filed various petitions disputing these assessments
In some cases we have received favorable decisions, which are currently being appealed by the respective governmental authorities
In other cases, our petitions have been denied and we are currently appealing those decisions
We currently estimate the range of possible losses related to matters for which Nextel Brazil has not accrued liabilities, as they are not deemed probable, to be between dlra74dtta1 million and dlra78dtta1 million as of December 31, 2005
We have entered into a number of agreements that are subject to enforcement in foreign countries, which may limit efficient dispute resolution
A number of the agreements that we and our operating companies enter into with third parties are governed by the laws of, and are subject to dispute resolution in the courts of or through arbitration proceedings in, the countries or regions in which the operations are located
We cannot accurately predict whether these forums will provide effective and efficient means of resolving disputes that may arise
Even if we are able to obtain a satisfactory decision through arbitration or a court proceeding, we could have difficulty enforcing any award or judgment on a timely basis
Our ability to obtain or enforce relief in the United States is also uncertain
Government regulations determine how we operate in various countries, which could limit our growth and strategic plans
In each market in which we operate, one or more regulatory entities regulate the licensing, construction, acquisition, ownership and operation of our wireless communications systems
Adoption of new regulations, changes in the current telecommunications laws or regulations or changes in the manner in which they are interpreted or applied could adversely affect our operations
Because of the uncertainty as to the interpretation of regulations in some countries in which we operate, we may not always be able to provide the services we have planned in each market
In some markets, we are unable, or have limitations on our ability, to offer some services, such as interconnection to other telecommunications networks and participation in calling party pays programs, which may increase our net costs
Further, the regulatory schemes in the countries in which we operate allow third parties, including our competitors, to challenge our actions
For instance, some of our competitors have challenged the validity of some of our licenses or the scope of services we provide under those licenses, in administrative or judicial proceedings, particularly in Chile
It is possible that, in the future, we may face additional regulatory prohibitions or limitations on our services
Inability to provide planned services could make it more difficult for us to compete in the affected markets
Further, some countries in which we conduct business impose foreign ownership limitations upon telecommunications companies
Finally, in some of our markets, local governments have adopted very stringent rules and regulations related to the placement and construction of wireless towers, which can significantly impede the planned expansion of our service coverage area, eliminate existing towers and impose new and onerous taxes and fees
These issues affect our ability to operate in each of our markets, and therefore impact our business strategies
In addition, local governments have placed embargoes on a number of our cell sites owned by our operating companies in 30 _________________________________________________________________ Argentina and Brazil
If we are not able to successfully overcome these embargoes, we may have to remove the cell sites and find a more acceptable location
See the “Regulatory and Legal Overview” discussion for each operating company under “Business — I Operating Companies
” If our licenses to provide mobile services are not renewed, or are modified or revoked, our business may be restricted
Wireless communications licenses and spectrum allocations are subject to ongoing review and, in some cases, to modification or early termination for failure to comply with applicable regulations
If our operating companies fail to comply with the terms of their licenses and other regulatory requirements, including installation deadlines and minimum loading or service availability requirements, their licenses could be revoked
Further, compliance with these requirements is a condition for eligibility for license renewal
Most of our wireless communications licenses have fixed terms and are not renewed automatically
Because governmental authorities have discretion as to the grant or renewal of licenses, our licenses may not be renewed or, if renewed, renewal may not be on acceptable economic terms
For example, under existing regulations, our licenses in Brazil and Peru are renewable once, but no regulations presently exist regarding how or whether additional renewals will be granted
Any modification or termination of our license or roaming agreements with Nextel Communications could increase our costs
Nextel Communications has licensed to us the right to use “Nextel” and other of its trademarks on a perpetual royalty-free basis in Latin America
However, Nextel Communications may terminate the license on 60 days notice if we commit one of several specified defaults (namely, failure to maintain agreed quality controls or a change in control of NII Holdings)
If there is a change in control of one of our subsidiaries, upon 30 days notice, Nextel Communications may terminate the sublicense granted by us to the subsidiary with respect to the licensed marks
The loss of the use of the “Nextel” tradename could have a material adverse effect on our operations
We also depend upon our roaming agreements with Nextel Communications for access to its iDEN network in the United States
We have identified material weaknesses in our internal control over financial reporting
As required by Section 404 of the Sarbanes-Oxley Act of 2002, our management has conducted an assessment of our internal control over financial reporting
As defined under the rules implementing Section 404, internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles
To evaluate the effectiveness of our internal control over financial reporting, management uses the criteria described in “Internal Control — Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission
In our 2004 annual report on Form 10-K and our quarterly reports on Form 10-Q for the quarters ended March 31, 2005, June 30, 2005 and September 30, 2005, we provided a detailed description of two material weaknesses over internal control over financial reporting we had identified at the time
In this 2005 annual report on Form 10-K, we continue to identify the existence of one material weakness in our internal controls over financial reporting
A material weakness is a significant deficiency or a combination of significant deficiencies that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected
Based on the material weaknesses we identified, and in accordance with the PCAOB standards, we concluded that our internal control over financial reporting was not effective as of the dates of the applicable quarterly and annual reports
We are in the process of developing and implementing remedial measures to address the material weakness in our internal control over financial reporting
We have extensive work remaining to test the remedial measures and to remedy this material weakness
There can be no assurance as to when the remediation plan will be implemented and successfully tested
Until our remedial efforts are completed, we 31 _________________________________________________________________ will continue to incur the expenses and management burdens associated with the additional resources and oversight required to prepare our consolidated financial statements
If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud
As a result, current and potential stockholders could lose confidence in our financial reporting, which would harm our business and the trading price of our stock
Effective internal controls are necessary for us to provide reliable financial reports and effectively prevent fraud
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate
We have in the past discovered, and may in the future discover, areas of our internal controls that need improvement
As initially discussed in our 2004 annual report on Form 10-K, we identified a material weakness related to the accounting for income taxes as a result of our assessment of internal controls over financial reporting in 2004 and in 2005
We are continuing to work to improve our internal controls
We cannot be certain that these measures will ensure that we implement and maintain adequate controls over our financial processes and reporting in the future
Any failure to implement required new or improved controls or difficulties encountered in their implementation could harm our operating results or cause us to fail to meet our reporting obligations
Inadequate internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our stock
Our debt limits our flexibility and increases our risk of default
Our debt could have important consequences to you, such as: • limiting our flexibility in planning for, or reacting to, changes in our business and the industries in which we compete and increasing our vulnerability to general adverse economic and industry conditions; and • limiting our ability to obtain additional financing that we may need to fund future working capital, capital expenditures, product development, acquisitions or other corporate requirements
As of December 31, 2005, the book value of our long-term debt was dlra1cmam148dtta8 million, including dlra350dtta0 million of 2dtta75prca convertible notes due 2025, dlra300dtta0 million of 2dtta875prca convertible notes due 2034, dlra91dtta5 million of 3dtta5prca convertible notes due 2033, dlra232dtta4 million for a syndicated loan facility, dlra124dtta8 million in obligations associated with the sale and leaseback of communication towers, dlra42dtta5 million in capital lease obligations and dlra7dtta6 million in spectrum license financing in Brazil
Our ability to meet our debt obligations and to reduce our indebtedness will depend on our future performance
Our performance, to a certain extent, is subject to general economic conditions and financial, business, political and other factors that are beyond our control
We cannot assure you that we will continue to generate cash flow from operations at or above current levels, that we will be able to meet our cash interest payments on all of our debt or that the related assets currently owned by us can be sustained in the future
If our business plans change, including as a result of changes in technology, or if we decide to offer new communication services or expand into new markets or further in our existing markets, as a result of the construction of additional portions of our network or the acquisition of competitors or others, or if economic conditions in any of our markets generally, or competitive practices in the mobile wireless telecommunications industry change materially from those currently prevailing or from those now anticipated, or if other presently unexpected circumstances arise that have a material effect on the cash flow or profitability of our mobile wireless business, then the anticipated cash needs of our business as well as the conclusions presented herein as to the adequacy of the available sources of cash and timing on our ability to generate net income could change significantly
Any of these events or circumstances could involve significant additional funding needs in excess of the identified currently available sources, and could require us to raise additional capital to meet those needs
In addition, we continue to assess the opportunities to raise additional funding on attractive terms 32 _________________________________________________________________ and conditions and at times that do not involve any of these events or circumstances and may do so if the opportunity presents itself
However, our ability to seek additional capital, if necessary, is subject to a variety of additional factors that we cannot presently predict with certainty, including: • the commercial success of our operations; • the volatility and demand of the capital markets; and • the future market prices of our securities
If we are unable to generate cash flow from operations in the future to service our debt, we may try to refinance all or a portion of our debt
We cannot assure you that sufficient future borrowings will be available to pay or refinance our debt
Our financing agreements have had and may contain covenants that limit how we conduct our business, which may affect our ability to grow as planned
As a result of restrictions that have been contained in certain of our financing agreements and may be contained in future financing agreements, we may be unable to raise additional financing, compete effectively or take advantage of new business opportunities
This may affect our ability to generate revenues and profits
Our current financing agreements have, and any future financing agreements may contain, covenants that limit how we conduct business by restricting our ability to: • incur or guarantee additional indebtedness; • pay dividends and make other distributions; • prepay subordinated indebtedness; • make investments and other restricted payments; • enter into sale and leaseback transactions; • create liens; • sell assets; and • engage in transactions with affiliates
We have significant intangible assets that are not likely to generate adequate value to satisfy our obligations in the event of liquidation
If we were liquidated, the value of our assets likely would not be sufficient to satisfy our obligations
We have a significant amount of intangible assets, such as licenses
The value of these licenses will depend significantly upon the success of our digital mobile network business and the growth of the SMR and wireless communications industries in general
Moreover, the transfer of licenses in liquidation would be subject to governmental or regulatory approvals that may not be obtained or that may adversely impact the value of such licenses
Our net tangible book value was dlra727dtta8 million as of December 31, 2005
Agreements with Motorola reduce our operational flexibility and may adversely affect our growth or operating results
We have entered into agreements with Motorola that impose limitations and conditions on our ability to use other technologies that would displace our existing iDEN digital mobile networks
These agreements may delay or prevent us from employing new or different technologies that perform better or are available at a lower cost because of the additional economic costs and other impediments to change arising under the Motorola agreements
For example, our infrastructure supply and installation services agreements with Motorola require that we must provide Motorola with notice of our determination that Motorola’s technology is no longer suited to our needs at least six months before publicly announcing or entering into a contract to purchase equipment utilizing an alternate technology
In addition, if Motorola manufactures, or elects to manufacture, the equipment utilizing the alternate technology that we elect to deploy, we must give Motorola the opportunity to supply 50prca of our infrastructure 33 _________________________________________________________________ requirements for the equipment utilizing the alternate technology for three years
This may limit our ability to negotiate with an alternate equipment supplier
We may not be able to finance a change of control offer
Upon the occurrence of certain kinds of change of control events, we may be required to repurchase the majority of the principal amount of all of our outstanding debt
Concerns about health risks associated with wireless equipment may reduce the demand for our services
Portable communications devices have been alleged to pose health risks, including cancer, due to radio frequency emissions from these devices
The actual or perceived risk of mobile communications devices could adversely affect us through increased costs of doing business, additional governmental regulation that sets emissions standards or otherwise limits or prohibits our devices from being marketed and sold, a reduction in subscribers, reduced network usage per subscriber or reduced financing available to the mobile communications industry
Further research and studies are ongoing, and we cannot be sure that these studies will not demonstrate a link between radio frequency emissions and health concerns
