The harmonized indicators initiative yielded a memorandum of understanding (MoU), signed in October 2013 in Washington, D.C., during the Private Sector Round table that takes place annually at the IMF-World Bank Annual Meetings, and an Addendum to the MoU, signed in the fall 2015.

The MoU, as amended by the Addendum, harmonizes the definitions of 38 indicators for private sector operations.
