Item 2.02              Results of Operations and Financial Condition.

On April 26, 2017, we issued a press release announcing our results of operations for the three-month period ended March 31, 2017.  A copy of that release is furnished herewith as Exhibit 99.1 and is incorporated herein by reference.

The press release includes forward-looking statements within the meaning of the Securities Act of 1933, as amended (the “Securities Act”) and the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  Such forward-looking statements are subject to risks and uncertainties, as disclosed from time to time in our filings with the Securities and Exchange Commission.  As a result of these factors, our actual results may differ materially from those indicated or implied by such forward-looking statements.

We also presented in the press release certain “non-GAAP” financial measures.  We presented our adjusted EBITDA, adjusted operating income (loss) and net debt for all periods presented in the release. The components of these non-GAAP measures are computed by using amounts that are determined in accordance with accounting principles generally accepted in the United States of America (“GAAP”).  Adjusted EBITDA is computed by subtracting the sum of direct costs, general and administrative expenses, and research and engineering expenses from the sum of operating revenues.  Adjusted operating income (loss) is computed similarly, but also subtracts depreciation and amortization expenses from the sum of operating revenues.  Net debt is calculated as total debt minus the sum of cash and cash equivalents and short-term investments. As part of the press release information, we have provided a reconciliation of adjusted EBITDA and adjusted operating income (loss) to income (loss) from continuing operations before income taxes and net debt to total debt which are the most closely comparable GAAP financial measures.

Management evaluates the performance of our operating segments and our consolidated results based on several criteria, including these non-GAAP measures, because it believes that these financial measures accurately reflect our ongoing profitability and performance.  There are, however, certain limitations to these measures and therefore they should be considered in addition to and not as an alternative to our results in accordance with GAAP.

The information in this Item 2.02, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to liabilities of that Section or Sections 11 and 12(a)(2) of the Securities Act.

Item 7.01.                                        Other Events.

On April 27, 2017, we will present certain information in connection with our call with shareholders, analysts and others relating to our results of operations discussed above.  Attached hereto as Exhibit 99.2 are slides that will be presented at that time.

The information included in this Current Report on Form 8-K under Item 7.01, including Exhibit 99.2, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that Section or Sections 11 and 12(a)(2) of the Securities Act.
