## Abstract

This final rule amends the Export Administration Regulations to implement the Wassenaar Arrangement's December 2005 agreement to revise the formula for calculating computer performance from Composite Theoretical Performance (CTP) measured in Millions of Theoretical Operations Per Second (MTOPS) to Adjusted Peak Performance (APP) measured in Weighted TeraFLOPS (Trillion Floating point Operations Per Second) (WT). This rule also establishes new control levels in Category 4 of the Commerce Control List (CCL) expressed in WT. In addition, this rule renames License Exception CTP to License Exception APP (Adjusted Peak Performance) to correspond to the new formula. This rule also makes conforming changes to the EAR based on the new computer parameter, such as, revising the parameters for eligibility of License Exception APP. This rule also moves Bulgaria from Computer Tier 3 to Computer Tier 1, removes High Performance Computer (XP) and Missile Technology (MT) controls from certain Export Control Classification Numbers (ECCNs) in Category 4 of the CCL, and removes the section of the EAR dedicated to various requirements for high performance computers.
