Three men convicted in the massive kickback and bribery scheme in New York City’s payroll modernization program were each sentenced to 20 years in prison Monday.

Southern District Judge George Daniels (See Profile) handed down the lengthy terms to Mark Mazer, Gerard Denault and Dmitry Aronshtein, convicted of several conspiracies in 2013 for their roles in the CityTime project scandal that netted them nearly $100 million.

“It is a classic tale of greed and corruption,” Daniels said, faulting the three for their lack of remorse and refusal to accept responsibility.

Mazer, 50, is a former consultant with the city’s Office of Payroll Administration who prosecutors said was the lead actor in the scheme. Denault, 52, was S.A.I.C.’s project manager for CityTime, and Aronshtein, 53, a subcontractor for the project.

Run by lead contractor Science Applications International Corporation (S.A.I.C.), CityTime ended up costing New York City almost $700 million, more than 10 times its original estimate. S.A.I.C. had to forfeit some $500 million under a 2012 settlement with the government.

Mazer is represented by Gerald Shargel, a partner at Winston & Strawn; Denault by Barry Bohrer, a partner with Schulte Roth & Zabel; and Aronshtein by Jeffrey Hoffman and Susan Wolfe, partners at Hoffman & Pollok.
