The $2 billion arms deal was exposed following the interim report of Buhari's investigations committee on arms procurement under the Goodluck Jonathan administration. The committee report showed extra-budgetary spending to the tune of N643.8 billion and additional spending of about $2.2 billion in the foreign currency component under the Goodluck Jonathan's watch. Preliminary investigation suggested that about $2 billion may have been disbursed for the procurement of arms to fight against Boko Haram insurgency in Nigeria.
