CHICAGO, May 17, 2010 — Navigant Consulting, Inc. (NYSE: NCI) announced today that it has acquired Daylight Forensic & Advisory LLC, an international regulatory consulting and investigative firm specializing in financial investigations, AML consulting, regulatory compliance, forensic technology services, and fraud risk management. Combining Daylight Forensic & Advisory’s industry expertise with Navigant’s Disputes and Investigations practice creates a significantly enhanced global investigative service offering, and reinforces Navigant’s strong New York presence.

“This combination is clearly a case of the whole being greater than the sum of its parts,” said William M. Goodyear, Chairman and Chief Executive Officer of Navigant. “Daylight’s market leading expertise in corporate investigations and compliance around AML, FCPA and fraud risk management, combined with Navigant’s deep forensic accounting capabilities, creates a comprehensive offering in the global investigations and compliance space. This combination comes at a critical time for our clients who are facing increasing regulatory pressure and risks associated with global business transactions.”

Daylight Forensic & Advisory is headquartered in New York City and the majority of their 65 consulting professionals are based there. Daylight Forensic & Advisory was founded in 2006 by Ellen Zimiles, Chief Executive Officer, and Joseph Spinelli, Chief Operating Officer. Zimiles has more than 25 years of litigation and investigation experience, including 10 years as a federal prosecutor in the Southern District of New York. She is a leading authority on AML programs, corporate governance, regulatory compliance, fraud control and public corruption matters.

Spinelli is a leading authority on white-collar crime with more than 30 years of forensic experience, including eight years as New York State’s first Inspector General, leading fraud, abuse, waste and corruption investigations for all New York State agencies and authorities. He also served as Assistant Director of Criminal Justice for the State of New York, with responsibilities for the investigation of criminal complaints and fraud allegations throughout state government. In February 2010, Spinelli was appointed by Governor Paterson of New York to the New York State Commission on Public Integrity.

“Pairing Daylight’s strong business investigations expertise with Navigant’s global reach and established forensic accounting practice enables our combined organization to provide both enhanced services to clients and broader opportunities to employees,” commented Zimiles. “Navigant’s client-centric focus is shared by all of us at Daylight, where our top experts have always worked side by side with clients.”

Daylight Forensic & Advisory’s professionals possess a wide range of law enforcement, legal, accounting and regulatory expertise as well as years of consulting and investigating experience. Daylight Forensic & Advisory’s experience includes advanced work in AML compliance, fraud investigations, forensic technology, regulatory compliance, forensic accounting, investigative due diligence, and litigation advisory with industry expertise in financial institutions, insurance, law firms, government agencies, healthcare providers, manufacturers, and pharmaceutical companies, among others.

The combination of deep technical skills with hands-on experience is the hallmark of the Navigant approach.

Under the terms of the acquisition agreement, Navigant paid $30 million in cash at the closing, with an additional $10 million cash payment payable on the one year anniversary of the transaction.
