Internal Controls
Policies and procedures designed to protect assets, ensure reliable accounting records, improve operations, and promote compliance with laws.
Who is ultimately responsible for internal controls?
Management is responsible for designing, implementing, and maintaining effective internal controls.
Fraud Triangle
Three conditions commonly associated with fraud: pressure, opportunity, and rationalization.
Fraud Triangle - Pressure
A financial or personal incentive that motivates someone to commit fraud, such as debt or unrealistic performance goals.
Fraud Triangle - Opportunity
A weakness in internal controls that allows someone to commit fraud without being easily detected.
Fraud Triangle - Rationalization
The justification a person uses to convince themselves that committing fraud is acceptable.
Control Activities
Specific policies and procedures used to prevent or detect errors, theft, and fraud.
Separation of Duties
Dividing authorization, recordkeeping, and custody of assets among different employees to reduce fraud risk.
Authorization Controls
Requiring designated employees to approve transactions before they occur.
Documentation Controls
Using invoices, receipts, and other records to provide evidence of transactions.
Physical Controls
Protecting assets through locks, safes, security cameras, passwords, and restricted access.
Independent Verification
Having someone who did not perform a transaction check its accuracy, such as reviewing a bank reconciliation.
Preventative Controls
Controls designed to stop mistakes or fraud before they occur, such as approval requirements and separation of duties.
Detective Controls
Controls designed to identify errors or fraud after they occur, such as audits and bank reconciliations.
Sarbanes-Oxley Act (SOX)
A 2002 federal law strengthening corporate financial reporting, internal control accountability, and auditor independence.
SOX Section 404
Requires public-company management to assess and report on internal control over financial reporting; certain companies also require auditor attestation.
Cash
Money available for immediate use, including currency, coins, checking accounts, and qualifying deposits. Asset; normal debit; permanent.
Cash Equivalents
Highly liquid short-term investments readily convertible to known cash amounts with insignificant value-change risk, generally maturing within three months of acquisition.
Cash and Cash Equivalents on Financial Statements
Reported together as current assets on the balance sheet, unless restrictions require different classification.
Accounts Receivable
Amounts customers owe from credit sales. Current asset; normal debit; permanent account.
Allowance for Uncollectible Accounts
Estimated receivables that will not be collected. Contra-asset; normal credit; permanent account.
Notes Receivable
Written promises to receive money, often with interest. Asset; normal debit; permanent account.
Inventory
Goods held for sale in normal business operations. Current asset; normal debit; permanent account.
Sales Revenue
Income earned from selling goods. Revenue account; normal credit; temporary account.
Sales Returns and Allowances
Reductions in sales for returned, defective, or damaged merchandise. Contra-revenue; normal debit; temporary account.
Sales Discounts
Reductions in sales revenue for customers who pay within discount terms. Contra-revenue; normal debit; temporary account.
Bad Debt Expense
Estimated cost of credit sales that will not be collected. Expense; normal debit; temporary account.
Cost of Goods Sold (COGS)
Cost of inventory sold to customers. Expense; normal debit; temporary account.
Permanent Accounts
Balance sheet accounts that carry balances into the next accounting period, including assets, liabilities, and equity.
Temporary Accounts
Revenue, expense, and dividend accounts that are closed at the end of the accounting period.
Normal Debit Balance
Assets, expenses, dividends, and contra-revenue accounts normally increase with debits.
Normal Credit Balance
Liabilities, equity, revenue, and contra-asset accounts normally increase with credits.
Net Sales Revenue Formula
Gross Sales Revenue - Sales Returns and Allowances - Sales Discounts = Net Sales Revenue.
Net Sales Calculation Example
Sales $50,000, returns $2,000, discounts $1,000: Net Sales = $47,000.
Allowance Method
Estimates uncollectible receivables and records bad debt expense in the period associated with the credit sales.
Journal Entry to Establish Allowance
Debit Bad Debt Expense; Credit Allowance for Uncollectible Accounts.
Journal Entry to Write Off Uncollectible Account
Debit Allowance for Uncollectible Accounts; Credit Accounts Receivable.
Does Writing Off a Receivable Create New Bad Debt Expense?
No. Under the allowance method, the expense was estimated previously.
Journal Entry to Recover a Written-Off Account
First debit Accounts Receivable and credit Allowance; then debit Cash and credit Accounts Receivable when collected.
Net Realizable Value of Accounts Receivable
Accounts Receivable - Allowance for Uncollectible Accounts = Estimated collectible amount.
Percentage of Sales Method
Estimates bad debt expense using a percentage of credit sales; focuses on the income statement.
Percentage of Receivables Method
Estimates the required ending allowance using a percentage of receivables; focuses on the balance sheet.
Aging of Receivables
Groups receivables by how long they are overdue and applies estimated uncollectible percentages to each group.
Adjusting the Allowance Account
Required ending credit balance minus existing credit balance equals adjustment; an existing debit balance increases the adjustment.
Multi-Step Income Statement
Income statement that separates operating and nonoperating items and calculates gross profit, operating income, and net income.
Benefit of Multi-Step Income Statement
Provides clearer information about gross profitability, operating performance, and other income or expenses.
Gross Profit Formula
Net Sales Revenue - Cost of Goods Sold = Gross Profit.
Gross Profit Percentage Formula
Gross Profit / Net Sales Revenue × 100 = Gross Profit Percentage.
Gross Profit Example
Net sales $80,000 and COGS $48,000: Gross Profit = $32,000.
Gross Profit Percentage Example
Gross profit $32,000 and net sales $80,000: Gross Profit % = 40%.
Operating Income Formula
Gross Profit - Operating Expenses = Operating Income.
Net Income Formula
Total Revenues and Gains - Total Expenses and Losses = Net Income.
Goods Available for Sale Formula
Beginning Inventory + Net Purchases = Goods Available for Sale.
Ending Inventory Formula
Goods Available for Sale - Cost of Goods Sold = Ending Inventory.
COGS Formula (Periodic System)
Beginning Inventory + Net Purchases - Ending Inventory = Cost of Goods Sold.
Inventory Calculation Example
Beginning inventory $10,000 + net purchases $30,000 - ending inventory $8,000 = COGS $32,000.
Four Inventory Cost Methods
Specific Identification, FIFO, LIFO, and Weighted Average.
Specific Identification
Tracks the actual purchase cost of each specific inventory item sold.
Specific Identification - Pros and Cons
Accurate for unique or expensive items but impractical for large quantities of similar products.
FIFO (First In, First Out)
Assumes the oldest inventory costs are assigned to COGS first, leaving newer costs in ending inventory.
FIFO - Pros and Cons
Often approximates physical flow and gives recent inventory costs on the balance sheet; during rising prices, typically produces higher reported income.
LIFO (Last In, First Out)
Assumes the newest inventory costs are assigned to COGS first, leaving older costs in ending inventory.
LIFO - Pros and Cons
During rising prices, generally produces higher COGS and lower taxable income; ending inventory may reflect outdated costs. Not allowed under IFRS.
Weighted Average Cost
Assigns inventory costs using an average unit cost; periodic average = total goods available cost / total units available.
Weighted Average - Pros and Cons
Smooths price fluctuations and is relatively simple; does not track exact individual item costs.
FIFO During Rising Prices
Typically results in lower COGS, higher ending inventory, and higher net income than LIFO.
LIFO During Rising Prices
Typically results in higher COGS, lower ending inventory, and lower net income than FIFO.
FIFO Calculation Example
Buy 10 units at $5 and 10 at $7; sell 12. FIFO COGS = (10 × $5) + (2 × $7) = $64.
LIFO Calculation Example
Buy 10 units at $5 and 10 at $7; sell 12. LIFO COGS = (10 × $7) + (2 × $5) = $80.
Weighted Average Calculation Example
Buy 10 units at $5 and 10 at $7. Average = $6/unit; selling 12 gives COGS $72.
Perpetual Inventory System
Updates inventory and COGS records continuously as purchases and sales occur.
Periodic Inventory System
Determines COGS and ending inventory at the end of the period using inventory counts and accounting calculations.
Perpetual vs. Periodic
Perpetual records COGS at each sale; periodic generally calculates COGS at period-end.
Merchandising Company
Purchases finished goods and resells them to customers without substantially changing the products.
Manufacturing Company
Produces finished goods using raw materials, labor, and manufacturing overhead.
Manufacturing Inventory Types
Raw Materials, Work in Process, and Finished Goods.
FOB Shipping Point
Ownership and risk generally transfer to the buyer when goods are delivered to the carrier; buyer generally pays freight.
FOB Destination (FOB Selling Destination)
Ownership and risk generally transfer when goods reach the buyer's destination; seller generally pays freight.
