COSO is non profit organisation. It has its head quarter at New York. COSO stands for Committee of Sponsoring Organizations of the Treadway Commission.
It is combined initiative to fight against corporate fraud.
Given : "An entity determined that its variable interest rate on borrowing will increase significantly in the near future. Consequently, the entity hedged its variable by locking in a fixed rate for the relevant period."
