The National Social Security Institute (НОИ, EIK 121082521) administers the Pensions fund and the other state social-security (DOO) funds. This page fuses its public procurement from the АОП register with the DOO fund's execution — so administrative spend is shown at the scale of the billions the fund actually pays out in pensions and benefits.
Beyond total awarded value, contracts and contractors, the breakdown shows procurement categories, strategic suppliers and administrative spend versus benefits paid. See also the state budget and public procurement.
