FACTBOX: Key elements of U.S. aid to Pakistan

WASHINGTON (Reuters) - U.S. Congress on Wednesday approved a law to triple nonmilitary aid to Pakistan to about $1.5 billion a year for the next five years as part of a plan to fight extremism.

It now goes to President Barack Obama to sign into law. Following are key elements of the legislation:

* The aid, which must be approved by congressional appropriators each year from 2010 to 2014, is intended to fund a range of development projects, including Pakistani schools and roads, agricultural development, energy generation, water resource management and the judicial system.

* The Obama administration must submit a report to Congress within 45 days of the law's enactment, laying out a plan for monitoring programs as well as key objectives for aid and a general description of programs to be funded.

* The administration must certify each year that "reasonable progress" is being made to meet the objectives of the aid.

* The administration has wide leeway in how it may use aid. The only amount earmarked is $150 million to be spent in 2010 for police equipping and training.

* The administration must submit a report twice a year to Congress listing people or entities that have received more than $100,000 for aid projects. This can be classified for security reasons.

* Any military aid must go through a civilian government. No security-related aid can be given from 2011 to 2014 unless Pakistan is cooperating to dismantle nuclear supplier networks and combat "terrorists," and its security forces must not subvert political or judicial processes.
