''TANGEDCO neither analysed the reasons for excess transit loss nor fixed any accountability on the contractor as the contract did not have any clause for recovering the same from the contractor despite knowing the quantity short delivered.'' The report also pointed to ''unproductive expenditure'' of Rs 55.34 crore by TANGEDCO vis-a-vis the Minimum Guaranteeed Quantity (MGQ) matter. While dwelling on MGQ, the report referred to ''...an erroneous excess expenditure of Rs 10.61 crore, which is recoverable.'' Also, it said TANGEDCO should ensure that coal shortages are recorded at regular intervals and recoveries be effected before closure of contract to protect financial interest. The government entity ''may prioritise the reconciliation of transit loss, as it is pending for more than 19 years.'' On TN Minerals Limited (report for year ended 31 March 2018), the audit said operation of a mine despite knowing the poor quality of granite resulted in infructuous expenditure of Rs 71 lakh.
