Verbatim excerpts. This is the contractor's contemporaneous announcement of its award, not an audited final obligation or proof of readiness. The federal task-order identifier is NOT in this announcement; do not infer it from later records.

"The Centers for Medicare & Medicaid Services (CMS) Center for Consumer Information and Insurance Oversight (CCIIO) has awarded CGI Federal Inc. (CGI), a wholly-owned U.S. operating subsidiary of CGI Group Inc. (NYSE: GIB) (TSX: GIB.A), a contract to build the U.S. government’s federally-facilitated health insurance exchange, Federal Exchange (FX). The contract has an estimated total contract value of US$93.7 million over a two-year base with three, one-year option periods. The US$55.7 million base contract has been awarded."
