To promote reciprocal openness and transparency, the Parties agreed on a Confidence-Building Measures Agreement (CBMA). The following are its key elements:

• The Parties agreed that the TMD systems subject to its provisions are: for the United States: the U.S. Army's Theater High-Altitude Area Defense (THAAD) system and the U.S. Navy's Theater-Wide TMD system; for the Russian Federation, Belarus, and Ukraine: the SA-12 system. (Kazakhstan does not possess the SA-12 system.) Additional lower-velocity TMD systems may in the future become subject to the CBMA's provisions as agreed upon by the Parties. All higher-velocity TMD systems will be subject to the CBMA.

• Ninety days after entry-into-force, the CBMA provides for an initial exchange of data, including data on each Party's own TMD systems and the components (i.e., launcher, interceptor missile, and radar) of each TMD system subject to the CBMA. The data will be updated annually by the Parties.

• The Parties are obligated to provide notifications regarding their respective country's test ranges from which TMD systems subject to the CBMA will be tested, and requires notification --10 days in advance -- of any test launches of interceptor missiles of TMD systems subject to the CBMA in which ballistic target-missiles are used.

• The Parties may provide additional information on a voluntary basis.

• The Parties will consider, within the Standing Consultative Commission (SCC), appropriate proposals to enhance the viability of the CBMA.

• Each Party may implement voluntary measures to enhance transparency, for example, through arranging demonstrations or tests of TMD systems which the other Parties may be invited to observe.

The CBMA will enter into force simultaneously with the Agreed Statements relating to lower- and higher-velocity TMD systems, and will remain in force as long as either of those Agreed Statements remains in force.
