Introduction :

The Banking Regulation Act, 1949 requires the auditor of a
banking company to state whether the profit and loss account shows a true
balance of profit and loss for the period covered by such account.

The profit and loss account as set out in Form B of the Third
Schedule to the Act has three broad heads : income, expenditure and
appropriations.

Interest/discount on advances/bills and interest on deposits
form a valuable component of income.

The auditor should, on a systematic sample basis, check the
rates of interest, etc., with sanctions and agreements and physical existence of
collateral security.

He should examine with the aid of Computer Assisted Audit
Tools (CAATs) — General Audit Software whether :

  • Interest has been
    charged on all performing accounts up to the date of the balance sheet.
    According to the guidelines for income recognition, asset classification,
    etc., issued by the Reserve Bank of India, a bank cannot take to income
    unrealised interest on any non-performing advance;

  • Discount on bills
    outstanding on the date of the balance sheet has been properly apportioned
    between the current year and the following year;

  • Interest on
    inter-branch balances has been eliminated in the consolidated profit and loss
    account of the bank; and

  • Any interest
    subsidy received (or receivable) from the Reserve Bank of India in respect of
    advances made at a concessional rates of interest is correctly computed.

The CAAT auditor may also co-relate the interest on
advances/deposits with the amount of outstanding advances/deposits outstanding
using advanced statistical functions like correlation.

Account maintenance :


Control objective : Non-recovery of service charges on
non-maintenance of minimum balance in saving and current accounts.


Control objective description : Saving and current
account holders need to mandatorily maintain a minimum quarterly balance in
their accounts.

The minimum balance to be maintained depends upon the type of
account (Saving general, current etc.), type of customer (Individual, staff,
pensioner, corporate salary account, etc.), cheque book issue status (issued,
not issued) and type of branch (urban, rural, etc.).

The minimum balance required to be maintained by each account
holder is entered in the core banking system by the branch under the field
‘minimum balance required’, in the CASA Master. Since this activity is performed
at the branch level and not the central IT level, it may be subject to branch
errors of commission.

Non-maintenance of the required minimum balance attracts a
system-levied service charge. Once again this service charge may be waived with
due permission (in case of dormant accounts for instance) or possibly with
certain mal-intentions at the account level by the branch by applying a flag ‘N’
in the field ‘SC MIN BAL FLAG’ in the CASA Master.

The bank auditor must verify the accuracy of both the
‘minimum balance required’ and ‘SC MIN BAL’ to be maintained in the CASA Master.

Procedure within GENERAL AUDIT SOFTWARE?:

    Open the CASA Master file within GENERAL AUDIT SOFTWARE.
    SAVING ACCOUNT WITH CHEQUE BOOK AND INCORRECT MIN BALANCE REQUIRED TO BE MAINTAINED — Perform data — Direct extraction on the CASA Master by applying the command?:

[@list(product code, “SB GEN”) .AND. cheque-book issued flag = “Y” .AND. @nomatch(customer type code, “STAFF”, ‘EX STAFF”, “PENSIONER”)

.AND. minimum balance required <> 1000].

This report will provide a list all saving accounts (other than NRE), who are not STAFF, EX-STAFF, PENSIONER, having a cheque-book facility and where minimum balance required to be maintained in the account as per the system is other than

Rs.1000. Rs.1000 is defined by the bank policy.

    SAVING ACCOUNT WITHOUT CHEQUE-BOOK AND INCORRECT MIN BALANCE REQUIRED TO BE MAINTAINED — Perform data — Direct extraction on the CASA Master by applying the command?:

This report will provide a list all saving accounts (other than NRE), who are not STAFF, EX-STAFF, PENSIONER, having no cheque book facility and where minimum balance required to be maintained in the account as per the system is other than Rs.500. Rs.500 is defined by the bank policy.

    CURRENT ACCOUNT WITH CHEQUE BOOK AND INCORRECT MIN BALANCE REQUIRED TO BE MAINTAINED — Perform data — Direct ex-traction on the CASA Master by applying the command?:

[@list(product code, “CURRENT”) .AND. chequebook issued flag = “Y” .AND. minimum balance required <> 5000].
This report will provide a list of all current accounts, having a cheque-book facility and where minimum balance required to be maintained in the account as per the system is other than Rs.5000. Rs.5000 is defined by the bank policy.

SAVING ACCOUNTS WITH CUMULATIVE WITH- DRAWALS FOR HALF YEAR — Perform Analysis — Summarisation on the above intermediate report. “Fields to Summarise” to be selected from drop down field list as “account number”. This intermediate report will provide an account wise summary of all withdrawals — cash, cheque, debit funds transfer for all SAVING accounts for the transaction period 8th April to 8th September 08 along with the number of withdrawals (i.e., entries).

    4. COMPUTATION OF SERVICE CHARGES — Perform — Data — Field manipulation — Append
— Virtual numeric field having name “Service Charges” to the intermediate report generated at Step 3 above. Enter the command no_of_recs

* 1 in the parameter. This new field will provide service charges (folio charges) to be recovered from the account holder towards excess with-drawals over 50 entries.

    5. IDENTIFYING SAVING ACCOUNTS WITH WITH-DRAWALS IN EXCESS OF 50 — Perform data — Direct extraction on the intermediate report generated at step 4 above by applying the command:

(no_of_recs > 50)

This final report will provide all SAVINGS ac-counts where half-yearly withdrawals are greater than 50 entries along with service charges to be recovered.

These cases can be checked physically with the Statement of Accounts for the relevant saving accounts in the final report for recovery of folio charges and the accuracy of charges recovered.

Temporary Overdraft Interest Charges:

 Non-recovery of interest on Temporary Overdrafts (TODs) granted to saving accounts.

Introduction:

TODs are granted by the bank to an account holder when the account holder is short of available balance to meet specific payments on his account. The TOD is granted under the assurance by the account holder that the temporary overdraft would be made good through incoming funds in transit. TODs can be System TODs or Adhoc TODs. An account holder should normally not be granted multiple TODs, until earlier TODs are regularised. TODs which are not regularised within the limit end date should be specially taken up for scrutiny. Consistent delay in regularisations on few accounts should be dealt with strictly through punitive action.

Method within General Audit Software:
  1.  Open CASA TOD Ledger within the General Audit Software.

  2.  SAVING ACCOUNT TOD INSTANCES GRANTED — Perform data — Direct extraction on the CASA TOD Ledger by applying the command — (product name = “SAVING”)

  3.  Open CASA ledger within GENERAL AUDIT SOFTWARE.

 4.  INTEREST CHARGED on SAVING ACCOUNT TOD INSTANCES — Perform data — Direct extraction on the CASA Ledger by applying the   command– (tran code = 5002 .AND. product   code = 101)

   Tran code 5002 stands for INTEREST DEBITS and PRODUCT CODE 101 stands for SAVING GENERAL accounts.

 6.  ACCOUNT SUMMARY LIST OF INTEREST CHARGED ON SAVING TODs — Perform Analysis — Summarisation on the intermediate report generated at Step 4. Select ‘account number’ as Fields to Summarise.

  7.  INTEREST NOT CHARGED ON SAVINGS TODs GRANTED — Perform — File — Join — select the intermediate report generated in Step 5 above as the Primary file. Select the intermediate report generated in step 6 above as the Secondary file. Click on Match. Match the two files on matching key — “account number” in Primary file and “account number” in Secondary file. Use the Join  condition “Records With No Secondary Match”.
