24.1 Substantive Testing of Business Cycles

Substantive Testing of Business Cycles

Substantive audit procedures represent the operational core of field testing in a financial statement audit. Governed by PSA 330 (The Auditor's Responses to Assessed Risks), substantive procedures are designed to detect material misstatements at the assertion level. Substantive procedures encompass tests of details (of classes of transactions, account balances, and disclosures) and substantive analytical procedures organized across five primary business operating cycles.

1. The Revenue and Collection Cycle

The revenue cycle comprises activities associated with selling goods or services to customers, billing, and collecting cash. Because revenue is a prime target for fraudulent financial reporting, PSA 240 establishes a rebuttable presumption that there are risks of fraud in revenue recognition. The primary audit risks are overstatement of revenue (Occurrence) and overstatement of accounts receivable (Existence).

Substantive Testing of Revenue Transactions

1. Sales Cut-Off Tests: The auditor verifies that sales transactions are recorded in the period in which control of the goods or services transferred to the customer under PFRS 15:
   • Select a sample of sales invoices recorded 5 to 10 business days before and after the balance sheet date.
   • Inspect corresponding delivery receipts, bills of lading, and shipping documents.
   • Confirm that shipping terms (e.g., FOB Shipping Point vs FOB Destination) were respected:
     • If goods were shipped FOB Destination on December 30, 2026, and delivered to the customer on January 4, 2027, recording revenue in 2026 represents a premature sales cutoff error that overstates 2026 revenue and understates 2026 inventory.
2. Testing for Fictitious Sales and Premature Recognition:
   • Vouch recorded sales entries in the sales journal to customer purchase orders, approved credit files, and signed shipping documents.
   • Scan sales journals for unusual large or round-sum transactions recorded immediately prior to year-end.
   • Inquire into sales contracts containing side agreements (e.g., liberal return rights, extended payment terms, or buy-back clauses).
3. Bill-and-Hold Transactions:
   • A bill-and-hold arrangement is an agreement where an entity bills a customer for a product but retains physical possession until transfer at a future date.
   • Under PFRS 15 (paragraph B81), revenue cannot be recognized until control passes, requiring all four conditions:
     1. The reason for the bill-and-hold arrangement must be substantive (requested by the customer, e.g., lack of storage space).
     2. The product must be identified separately as belonging to the customer.
     3. The product currently must be ready for physical transfer to the customer.
     4. The entity cannot have the ability to use the product or to direct it to another customer.

Substantive Testing of Trade Accounts Receivable

1. External Confirmation Procedures (PSA 505):
   • The auditor sends confirmation letters directly to customers sampled from the aged accounts receivable subsidiary ledger.
   • Handling Non-Responses to Positive Confirmations: When customers do not respond to initial and follow-up positive confirmation requests, the auditor must perform alternative audit procedures:
     • Examining subsequent cash collections received after year-end (inspecting bank deposit slips, official receipts, and bank statements matching specific invoice numbers).
     • Inspecting customer purchase orders, sales contracts, internal shipping documents (bills of lading, delivery receipts), and sales invoices.
2. Evaluation of Allowance for Expected Credit Losses (ECL) under PFRS 9:
   • Review management's provision matrix and historical loss rates, evaluating forward-looking macroeconomic factors (inflation, GDP growth, interest rates).
   • Test the accuracy of the aging of accounts receivable by vouching sample invoice dates.
   • Inquire regarding significantly past-due balances, disputed billings, or customers undergoing corporate rehabilitation or insolvency proceedings.

2. The Expenditure and Disbursement Cycle

The expenditure cycle covers purchasing goods and services, recording liabilities, and disbursing cash. The primary audit risk is understatement of liabilities and expenses (Completeness) to artificially inflate net income and improve working capital ratios.

The Search for Unrecorded Liabilities (Out-of-Period Liability Search)

The search for unrecorded liabilities is the most critical substantive procedure for accounts payable. The auditor performs the following steps:

1. Review Subsequent Cash Disbursements: Obtain the cash disbursements journal, check registers, and bank statements for the period immediately following year-end (e.g., January 1 to February 28).
2. Examine Voucher Documentation: For disbursements exceeding a specified dollar threshold, inspect the underlying vendor invoice and receiving report to determine when the goods were received or services rendered.
3. Assess Cutoff: If the goods were received or services were performed on or before December 31, trace the transaction to the year-end accounts payable subsidiary ledger:
   • If the item is included in the December 31 accounts payable balance: properly accounted for.
   • If the item is omitted from December 31 accounts payable: an unrecorded liability exists. The auditor calculates the misstatement and adds it to the Summary of Unadjusted Audit Differences (SUAD).
4. Review Unmatched Receiving Reports: Inspect receiving reports dated on or before December 31 for which no vendor invoice had arrived by year-end (unbilled goods received). Verify that an appropriate accrual was recorded at year-end.
5. Confirm Accounts Payable with Suppliers: Send confirmation requests to major active suppliers, vendors with zero balances at year-end, and vendors with fluctuating balances (blank form confirmations are preferred).

3. The Inventory and Production Cycle

Inventory is often the largest current asset on the balance sheet, highly susceptible to physical theft, obsolescence, and valuation manipulation. Governed by PSA 501 (Audit Evidence - Specific Considerations for Selected Items) and PAS 2 (Inventories), substantive procedures focus on Existence, Completeness, and Valuation.

Physical Inventory Count Observation (PSA 501)

Pursuant to PSA 501, if inventory is material to the financial statements, the auditor shall obtain sufficient appropriate audit evidence regarding the existence and condition of inventory by attending physical inventory counting, unless impracticable.

The Auditor's Role During the Count

• The auditor observes, rather than conducts, the count. Management is responsible for counting the inventory; the auditor observes the client's count procedures, assesses compliance with written count instructions, and performs independent test counts.
• Dual-Direction Test Counts:
  • Floor to Count Sheets (Completeness): The auditor selects physical items on the warehouse floor and traces them to the client's count tags/sheets. Ensures all physical items are recorded.
  • Count Sheets to Floor (Existence): The auditor selects recorded items from the client's count sheets and inspects the physical goods on the warehouse floor. Ensures recorded items physically exist.
• Cutoff Documentation: The auditor records the document numbers of the last receiving report and the last shipping document used prior to or during the physical count. This allows the auditor to verify that post-count inventory reconciliations align with the sales and purchases cutoffs.

Goods in Transit and Consignments

Pricing and Valuation Testing (PAS 2)

Under PAS 2, inventories must be measured at the lower of cost and net realizable value (LCNRV):

$\text{Net Realizable Value } (NRV) = \text{Estimated Selling Price} - \text{Estimated Costs of Completion} - \text{Estimated Costs Necessary to Make the Sale}$

• Testing Unit Costs: Test purchase invoices against the client's cost-flow formula (FIFO or weighted average). For manufacturers, test standard costing variance allocations (raw materials, direct labor, manufacturing overhead) under PAS 2.
• Testing NRV: Compare recorded unit cost against actual subsequent selling prices realized in January/February, net of commissions, freight, and packaging costs. If $NRV < \text{Cost}$, verify that a write-down to allowance for inventory obsolescence was recorded through profit or loss.

4. The Payroll and Personnel Cycle

The payroll cycle involves hiring, wage calculation, statutory deductions, and cash disbursements. Unlike inventory or receivables, payroll is dominated by high-volume, highly recurring transactions with relatively small balance sheet accruals at year-end. The primary testing method is Substantive Analytical Procedures complemented by statutory compliance verification.

• Overtime vs Production Vol.         • Home Dev. Mutual Fund (Pag-IBIG)     • Auditor witnesses physical
• Accrued 13th Month Pay Recalc.      • BIR Withholding Tax on Comp.           cash/envelope distribution.

Core Substantive Procedures for Payroll

1. Substantive Analytical Procedures:
   • Develop an independent auditor expectation of annual gross payroll: $\text{Expected Payroll} = \text{Number of Full-Time Equivalent Employees (FTE)} \times \text{Average Base Wage Rate} \times (1 + \text{Percentage Merit Increase})$.
   • Compare monthly payroll expenses across departments against budgeted headcount and prior year actuals.
   • Recompute accrued 13th Month Pay mandated under Presidential Decree No. 851, ensuring that $1/12$ of total basic salary earned during the calendar year is accrued.
2. Testing Statutory Deductions in the Philippines:
   • Select a sample of individual employee payroll calculations from the monthly payroll registers and verify compliance with statutory deduction tables:
     • Social Security System (SSS): Verify employer and employee share contributions against SSS salary brackets, including Mandatory Provident Fund (WISP).
     • Philippine Health Insurance Corporation (PhilHealth): Verify deduction percentages against the statutory premium rate.
     • Home Development Mutual Fund (Pag-IBIG): Verify mandatory monthly contributions.
     • Bureau of Internal Revenue (BIR): Verify withholding tax computations against revised withholding tax tables under the TRAIN Law (Republic Act No. 10963) and verify annual BIR Form 2316 filings.
3. Surprise Payroll Payoffs (Detecting "Ghost Employees"):
   • When internal controls over cash payroll or timekeeping are weak, or fraud is suspected, the auditor performs a surprise payroll distribution.
   • The auditor accompanies the paymaster during the actual distribution of paychecks or cash envelopes. Each employee must present valid government photo identification and sign for their pay in the presence of the auditor.
   • Unclaimed paychecks or pay envelopes must be retained by the auditor for investigation to detect fictitious ("ghost") employees.

5. The Financing and Investing Cycles

The financing and investing cycles encompass transactions relating to long-term capital (equity, debt) and capital allocation (cash management, investments, property, plant, and equipment).

Substantive Testing of Cash and Cash Equivalents

Cash is the most liquid asset, carrying supreme inherent risk of misappropriation, theft, and cutoff distortion.

1. Bank Confirmation Letters: The auditor sends standard electronic or paper bank confirmation requests to all commercial banks where the client held accounts, loans, or lines of credit during the year, including accounts closed during the period.
2. Testing Year-End Bank Reconciliations:
   • Obtain client-prepared bank reconciliations for all bank accounts as of December 31.
   • Trace the ending bank balance to the direct bank confirmation.
   • Trace the ending book balance to the general ledger cash account.
   • Vouch Deposits in Transit: Inspect subsequent bank statements (cutoff bank statements) to verify that deposits in transit cleared the bank within 1 to 3 business days following year-end.
   • Vouch Outstanding Checks: Inspect canceled/cleared checks in the cutoff bank statement to verify that checks written on or before December 31 were properly listed as outstanding.
3. Cutoff Bank Statement: A bank statement covering 7 to 14 days immediately following the balance sheet date, sent directly by the bank to the auditor, used to verify reconciling items.
4. Detecting Kiting and Lapping:
   • Kiting: Transferring money from one bank account to another and recording the transaction improperly so that cash is counted simultaneously in both bank accounts at year-end, artificially inflating cash balances.
     • Detection: The auditor prepares an Interbank Transfer Schedule, checking the dates of withdrawal and deposit per books and per bank around year-end.

   ────────────────────────────────────────────────────────────────────────────────────────────

• Lapping: The postponement of entries for the collection of receivables to conceal an existing cash shortage (stealing Customer A's payment, applying Customer B's subsequent payment to Customer A's account, and repeating).
  • Detection: Comparing details of bank deposit slips against customer remittance advices and daily cash receipt journal postings.

Substantive Testing of Investments (PFRS 9)

• Inspect physical stock and bond certificates in the vault, or obtain direct confirmation from independent custodians, depository agents (e.g., Philippine Depository & Trust Corp. - PDTC), or brokers.
• Verify classification under PFRS 9:
  • Fair Value Through Profit or Loss (FVTPL)
  • Fair Value Through Other Comprehensive Income (FVTOCI)
  • Amortized Cost
• Verify fair value measurement: Vouch year-end market quotations to the Philippine Stock Exchange (PSE) or Bloomberg/Reuters pricing feeds.

Substantive Testing of Property, Plant, and Equipment (PPE)

• Vouch Additions: Inspect supplier contracts, invoices, board approvals, and installation completion certificates for significant capital expenditures during the year.
• Search for Unrecorded Retirements: Inquire regarding decommissioned assets, analyze scrap sales revenue, review insurance policies for cancelled coverage, and inspect the physical plant floor.
• Analyze Repairs and Maintenance: Vouch large debit entries in repairs and maintenance expense to ensure capitalizable replacements or betterment costs under PAS 16 were not improperly expensed.
• Recalculate Depreciation and Impairment: Independently recompute depreciation expense under PAS 16; assess whether triggers for asset impairment under PAS 36 exist.
