EXPLANATORY NOTE

This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends our Annual Report on Form 10-K (the “Original Annual Report”) for the year ended December 31, 2005, which was originally filed with the Securities and Exchange Commission on June 16, 2006. We are filing this Amendment solely to enhance our disclosure regarding controls and procedures and the material weaknesses in our internal controls over financial reporting described in Item 9A. In particular, our revised Item 9A discussion included herein provides greater specificity with respect to:

 

    when the material weaknesses were identified, by whom they were identified and when we believe they began;
    the scope and quantity of our projects which were affected by our material weakness relating to construction contract management; and
    the nature and timing of the significant measures that we took in 2005 to remediate our material weaknesses.

We have included as exhibits to this Amendment new certifications of our chief executive officer and chief financial officer.

Except as described above, no attempt has been made in this Amendment to modify or update other disclosures presented in the Original Annual Report. This Amendment does not reflect events occurring after the filing of the Original Annual Report or modify or update those disclosures affected by subsequent events. Accordingly, this Amendment should be read in conjunction with our filings with the SEC subsequent to the filing of the Original Annual Report, including any amendments to those filings.

PART II.

Item 9A. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports filed or submitted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to management, including the principal executive and financial officers, as appropriate to allow timely decisions regarding required disclosure. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

An evaluation was performed under the supervision and with the participation of the Company’s management, under the supervision of our principal executive officer (CEO) and principal financial officer (CFO), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of December 31, 2005. Based on that evaluation and the material weakness in internal control over financial reporting described in (b) below, our CEO and our CFO have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), were not effective to ensure the information required to be disclosed by us in reports that we file or submit under the Exchange Act is properly recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

(b) Management’s Report on Internal Control Over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Our internal controls were designed to provide reasonable assurance as to the reliability of our financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with generally accepted accounting principles in the United States, as well as to safeguard assets from unauthorized use or disposition.

Due to inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of control effectiveness to future periods are subject to the risk that the controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management of the Company made an assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005. In making this assessment, management used the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and concluding on this evaluation. Based on this evaluation and the identification of the material weaknesses discussed below, management concluded that the Company did not maintain effective internal control over financial reporting as of December 31, 2005.

Company-Level Controls: A material weakness in our internal control over financial reporting exists related to the Company’s financial statement close process. The weakness was identified by our accounting management during the assessment of our internal control system in December 2005 and was determined to be a material weakness in April of 2006. This weakness in our company-level controls resulted in delays in our ability to timely close our books and records during 2005. Such delays in closing the books and records are at least in part a contributing factor to the delays we have experienced in filing our quarterly and annual financial statements with the SEC. This material weakness resulted primarily from insufficient staffing of qualified accounting personnel.

We believe that this weakness began in January 2005 as the Company’s accounting staff began to respond to a number of resource demands, including a larger than normal turnover of international and corporate accounting personnel; a significant increase in the workload of the accounting staff as they supported the Audit Committee’s independent investigation as well as investigations by the SEC and the Department of Justice; and a substantial increase in the volume of accounting transactions associated with the 46 percent annual increase in the Company’s revenue.

Construction Contract Management: A material weakness exists related to controls over the project reporting used in the accounting process. This weakness existed throughout 2005 and is a continuation of a material weakness reported in our 2004 Form 10-K, which was first identified by management in March of 2005. Management of the Company determined that the weakness had not been fully remediated during reviews of the project cost estimates used in the accounting process in closing the quarters ended September 30, and December 31, 2005. The weakness primarily impacts three large Nigerian contracts, with a total contract value of approximately $620 million, for which cost estimates were not updated to reflect current information and insufficient measures were taken to independently verify uniform and reliable cost estimates. This material weakness could materially affect project related accounts, and it specifically resulted in material changes to revenue and cost of sales on contracts during the preparation of our preliminary financial statements by our accounting staff prior to the issuance of the financial statements.

Because of the material weaknesses described above, management concluded that as of December 31, 2005, the Company did not maintain effective internal control over financial reporting based upon the criteria described above.

GLO CPAs LLP, an independent registered accounting firm, audited management’s assessment of the effectiveness of the Company’s internal control over financial reporting. GLO CPAs LLP issued an audit report thereon, which is included in this Annual Report on Form 10-K.

(c) Changes in Internal Control over Financial Reporting

During the course of 2005, we undertook significant efforts to improve our internal control over financial reporting. These significant changes included the following:

 

    Initiation of an enhanced worldwide awareness program to educate employees with respect to the content of our whistleblower policy to achieve better reporting of any suspected problems.

 

    Implementation of an “enhanced and stand-alone” FCPA Compliance Program separate from that incorporated into our Code of Business Conduct and Ethics. This enhanced FCPA Compliance Program includes the training of Company personnel by the Company’s General Counsel or outside legal counsel.

Table of Contents
    Realignment of the reporting of all business units’ financial staffs directly to the Corporate Controller’s Office.

 

    Expansion of the International and Corporate accounting and finance staff by 133% during 2005 to strengthen existing internal controls over project management, cash disbursements, tax compliance, and financial reporting.

 

    Movement of the internal audit function from an outsourced function with an independent accounting firm to an experienced in-house department to facilitate more frequent and more in-depth examinations of controls throughout the Company.

 

    Adoption of a more frequent rotation policy for the staff at our international business units.

(d) Remediation Activities

Company management with oversight from the Audit Committee has devoted substantial effort to the remediation of its material weakness described in (b) above and to making improvements in our internal control over financial reporting. Specifically, subsequent to December 31, 2005, we are actively working to strengthen our accounting and finance team to correct the identified material weakness in our internal controls and our efforts include:

 

    The hiring of additional senior accounting personnel at both the business unit level and the corporate administrative offices during the first five months of 2006;

 

    The initiation of efforts to develop more standardized and timely project management reporting and management review processes through documentation, training, and retention of personnel;

 

    The recruitment of other candidates with the intention of expeditiously filling vacancies in our accounting, finance, and project management teams;

 

    The continued review and monitoring of the accounting department structure and organization, both in terms of size and expertise; and

 

    The conducting of additional training and increased supervision of accounting personnel.

We believe the implemented and planned changes to our internal control over financial reporting and our disclosure controls and procedures will be adequate to provide reasonable assurance that the information required to be disclosed in our Exchange Act reports is properly recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, as appropriate, to allow timely decisions regarding required disclosures. Specifically, we believe the additional accounting personnel, and in particular, additional supervisory personnel, will allow us to ensure that all control procedures related to closing our books and preparing financial statements, such as reconciliations and analyses, are properly performed and reviewed. The additional supervisory personnel in the project accounting area will allow us to continue to improve our review of monthly project results and estimates prior to closing the books and preparing the financial statements. The reorganization of our accounting department structure will continue to provide for additional supervision of Nigerian project accounting personnel. Finally, we have provided accounting personnel with training in Sarbanes Oxley controls documentation and information systems use, which has helped improve internal control awareness and compliance.
