Letter of Undertakings (LOUs) issued by the Punjab National Bank (PNB) are said to be a fund-based facility. The LOUs issued by PNB and outstanding money collected thereon, and foreign exchange paid against the LOUs by other banks abroad at the end of each financial year should have been reconciled by the statutory auditors who certified the PNB's annual accounts.
