We will be required to devote significant management attention and resources to integrating the business practices and operations of NDS with our business. We may be unable to realize the planned synergies from the acquisition or other benefits in the timeframe that we expect or at all. We continue to assess synergies that we may realize as a combined company, the realization of which will depend on a number of factors.

Read in the 10-K

Additional difficulties we may encounter as part of the integration process include the following:

•the costs of integration and compliance and the possibility that the full benefits anticipated to result from our acquisition of NDS will not be realized;

•any delay in the integration of management teams, strategies, operations, products and services;

•diversion of the attention of each company’s management as a result of our acquisition of NDS;

•differences in business backgrounds, corporate cultures and management philosophies that may delay successful integration;

•operating in foreign jurisdictions where we have no prior operating experience, including compliance, workforce and operational challenges;

•the ability to create and enforce uniform standards, controls, procedures, policies and information systems;

•the challenge of integrating complex systems, technology, networks and other assets of NDS into those of ours in a seamless manner that minimizes any adverse impact on customers, suppliers, employees and other constituencies;

•potential unknown liabilities and unforeseen increased expenses or delays associated with the acquisition, including costs to integrate NDS beyond current estimates; or

•the disruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies.

Any of these factors could adversely affect each company’s ability to maintain relationships with customers, suppliers, employees and other constituencies or our ability to achieve the anticipated benefits of the acquisition or could reduce each company’s earnings or otherwise adversely affect our business and financial results after the acquisition. These risks are not limited to our acquisition of NDS and could also apply to our future acquisitions.

Uncertainties associated with our acquisition of NDS may cause a loss of management personnel and other key employees, which could adversely affect our future business, operations and financial results.

The acquisition of NDS could disrupt our and NDS’ businesses. We are dependent on the experience and industry knowledge of senior management and other key employees to execute our business plans, which could be disrupted by the unanticipated departure of any key member of our management team or employee base, as well as management or key employees of NDS. Our and NDS’ current and prospective employees may experience uncertainty about their roles within our company, which may have an adverse effect on the ability of each of us to attract or retain key management and other key personnel.

Accordingly, no assurance can be given that we will be able to attract or retain our and NDS’ key management personnel and other key employees to the same extent that our companies have previously been able to attract or retain such employees. In addition, because of the specialized and technical nature of our business, our future performance is dependent on the continued service of, and on our ability to attract and retain, qualified management, engineering,

technical, marketing and support personnel. Competition for such personnel is intense, and we may be unable to continue to attract or retain such personnel.

Our results after our acquisition of NDS may suffer if we do not effectively manage our expanded operations following the acquisition or the business of NDS may underperform relative to our expectations.

Following our acquisition of NDS, the size and complexity of our business will increase significantly beyond the current size of either our or NDS’ existing business. Our future success depends, in part, upon our ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and new types of manufacturing processes and products and associated increased costs and complexity. There can be no assurances that we will be successful after completion of the acquisition or that we will realize the expected benefits currently anticipated from our acquisition of NDS.

Additionally, we may not be able to maintain the levels of revenue, earnings or operating efficiency that we and NDS have achieved or might achieve separately. The business and financial performance of NDS is subject to certain risks and uncertainties, including the risk of the loss of, or changes to, its relationships with its customers. We may be unable to achieve the same growth, revenues and profitability that NDS has achieved in the past.

Integration efforts may result in significant costs and divert management attention and resources. These matters could adversely affect our business and financial results for an extended period following the completion of such transaction.
