Internal Control and Cash

The Fraud Triangle

The Fraud Triangle is a foundational concept in internal control, explaining the three elements that must be present for fraud to occur: motive, opportunity, and rationalization. Understanding these elements helps organizations design controls to prevent fraud.

  • Motive: The reason or incentive for committing fraud, such as financial pressure.

  • Opportunity: The ability to commit fraud, often due to weak internal controls.

  • Rationalization: The justification or reasoning that makes the act acceptable to the perpetrator.

The Function of an Internal Control System

Internal controls are designed to protect company assets and ensure the reliability of financial reporting. They serve as barriers against fraud, waste, and inefficiency.

  • Fraud: Intentional misrepresentation or theft.

  • Waste: Inefficient use of resources.

  • Inefficiency: Failure to maximize productivity or minimize costs.

The Components of Internal Control

An effective internal control system consists of several interrelated components, often illustrated as a house structure. These components work together to ensure the integrity of financial information and safeguard assets.

  • Control Environment: The overall attitude, awareness, and actions of management and employees regarding internal controls.

  • Risk Assessment: Identifying and analyzing risks that may affect the achievement of objectives.

  • Control Procedures: Policies and procedures that help ensure management directives are carried out.

  • Information System: Methods for recording, processing, and reporting financial data.

  • Monitoring: Ongoing review of controls to ensure they are effective.

Internal Control Procedures

Specific procedures are implemented to achieve the objectives of internal control:

  • Smart Hiring Practices: Background checks, training, supervision, competitive salaries, and clear responsibilities.

  • Separation of Duties: Dividing responsibilities for asset handling, record keeping, and transaction approval to reduce risk of error or fraud.

  • Adequate Records: Maintaining detailed, prenumbered documents for all business transactions.

  • Information Technology: Using electronic systems (e.g., sensors, bar codes) to improve accuracy and speed.

Cash Receipts by Mail

Proper controls over cash receipts by mail are essential to prevent theft and ensure accurate recording. The process involves multiple departments and steps to safeguard cash.

  • Mailroom opens mail and separates checks from remittance advices.

  • Treasurer deposits checks and prepares deposit ticket.

  • Accounting department records remittance advices and updates cash records.

  • Controller verifies total amount credited to cash.

Controls Over Payment by Check

To prevent unauthorized payments, duties related to purchasing, receiving goods, preparing payments, and approving payments are separated. A payment packet typically includes a purchase order, invoice, and receiving report.

  • Purchase Order: Authorizes purchase.

  • Invoice: Documents the amount owed.

  • Receiving Report: Confirms goods were received.

Bank Reconciliation and Journalizing Transactions

Bank reconciliation compares the company's cash records with the bank statement to identify discrepancies. Adjustments are journalized to reflect accurate cash balances.

  • Bank Side: Deposits in transit, outstanding checks, bank errors.

  • Book Side: Bank collections, electronic funds transfers, service charges, interest revenue, NSF checks, cost of printed checks, book errors.

Receivables and Revenue

Revenue Recognition under GAAP

Revenue is recognized when it is earned, typically when goods are delivered or services performed. The amount recorded is the cash received or the fair market value of assets received.

  • Five-step process for revenue recognition:

    1. Identify the contract(s).

    2. Identify the performance obligation(s).

    3. Determine the transaction price.

    4. Allocate the transaction price to performance obligations.

    5. Recognize revenue when obligations are satisfied.

Sales Returns and Allowances

Customers may return unsatisfactory or damaged goods. Businesses estimate sales returns and allowances to adjust revenue and inventory accordingly.

  • Sales Refunds Payable: Liability for expected refunds.

  • Inventory Returns Estimated: Asset adjustment for goods expected to be returned.

Sales Discounts

Sales discounts incentivize early payment. For example, "2/10, n/30" means a 2% discount if paid within 10 days; otherwise, full payment is due in 30 days.

  • Sales Discount: Reduces revenue and encourages prompt payment.

Types of Receivables

Receivables are monetary claims against others and are classified as current assets. They arise from selling goods/services (accounts receivable) or lending money (notes receivable).

  • Accounts Receivable: Amounts owed by customers.

  • Notes Receivable: Formal written promises to pay.

Allowance for Uncollectible Accounts

Companies estimate uncollectible accounts to match expenses with revenues. The allowance method records estimated losses and uses a contra account to show expected uncollectibles.

  • Percent-of-Sales Method: Estimates expense as a percentage of sales (income statement approach).

  • Aging-of-Receivables Method: Analyzes specific accounts based on age (balance sheet approach).

Inventory and Cost of Goods Sold

Inventory Accounting

Inventory is recorded as an asset until sold, at which point its cost is transferred to expense (Cost of Goods Sold) on the income statement. Gross profit is the excess of sales revenue over cost of goods sold.

  • Inventory: Asset on the balance sheet.

  • Cost of Goods Sold: Expense on the income statement.

  • Gross Profit:

Periodic vs. Perpetual Inventory Systems

Inventory systems track goods bought, sold, and on hand. The perpetual system maintains continuous records, while the periodic system updates records at intervals.

  • Perpetual System: Used for all goods; continuous tracking.

  • Periodic System: Used for inexpensive goods; periodic tracking.

Inventory Costing Methods

Companies may use different methods to assign costs to inventory and cost of goods sold:

  • Specific-Identification Method: Tracks individual items.

  • Average-Cost Method: Uses weighted average cost.

  • First-In, First-Out (FIFO) Method: First costs in are first costs out.

  • Last-In, First-Out (LIFO) Method: Last costs in are first costs out.

Income Effects of FIFO, LIFO, and Average-Cost Methods

The choice of inventory method affects cost of goods sold, gross profit, and tax liability. FIFO yields lowest cost of goods sold and highest gross profit when prices rise; LIFO yields highest cost of goods sold and lowest gross profit.

Tax Advantages of LIFO

When costs are rising, LIFO results in lower taxable income and lower income taxes, increasing available cash. FIFO provides more up-to-date inventory cost for the balance sheet.

Lower-of-Cost-or-Market (LCM) Rule

The LCM rule requires inventory to be reported at the lower of its historical cost or market value (net realizable value), ensuring relevance and representational faithfulness in financial statements.

  • Disclosure: Sufficient information for decision-making.

  • Consistency: Use comparable methods from period to period.

Inventory Turnover and Days Inventory Outstanding (DIO)

These ratios measure how efficiently inventory is managed and sold.

  • Inventory Turnover:

  • Days Inventory Outstanding (DIO):

A higher turnover indicates rapid sales; a lower DIO means inventory is sold quickly.
