RRI required that all expenditure from Belipola go through head office. In the past, money was requested through the "budget requisition form" and then approved by head accountant at RRI. Then checks are passed to either company director (Mr. Charith Senanayake) or company chairman (Dr. Ranil Senanayake). After checks are signed they can be deposited into the account at Belipola. This system is up to date as of December 2015, but may have changed in January, 2016.
