Item 2.02 Results of Operations and Financial Condition

Navigant  Consulting,  Inc.  has  reported  its first  quarter  2006  results of
operations.  The Company's  press release  dated April 27, 2006  announcing  the
results for the first quarter 2006 is attached hereto as Exhibit 99.1.

The press release presented non-GAAP financial information, such as EBITDA
(earnings before interest, taxes, depreciation and amortization), which is not a
measure of financial performance under generally accepted accounting principles.
The Company believes EBITDA is useful supplemental information for investors to
evaluate financial performance. This data is also used by the Company for
assessment of its operating and financial results, in addition to operating
income, net income and other GAAP measures. Management believes EBITDA is a
useful indicator of the Company's financial and operating performance and its
ability to generate cash flows from operations that are available for taxes and
capital expenditures. Investors should recognize that EBITDA might not be
comparable to similarly-titled measures of other companies. This measure should
be considered in addition to, and not as a substitute for or superior to, any
measure of performance prepared in accordance with accounting principles
generally accepted in the United States.
