Accounting 101: Comprehensive Study Guide and Problem Set and Review Guide

ACCOUNTS RECEIVABLE AND UNCOLLECTIBLE ACCOUNTS

Accounts Receivable (A/R) Lifecycle
  • Definition: Accounts receivable represent promises from customers for services or products provided on credit (A/R=Assets created by selling on creditA/R = \text{Assets created by selling on credit}).
  • Accounting for A/R Balances:
    • The Subsidiary Ledger: Also known as the Accounts Receivable Ledger, it is used to maintain individual accounts for each customer to track their specific outstanding balances.
    • Balance Calculation Example:
      • Beginning Balance: $52,000\$52,000
      • Collections on account: $14,800\$14,800 (Decreases A/R)
      • Additional services on account: $12,500\$12,500 (Increases A/R)
      • Cash received for future services: $5,000\$5,000 (Recorded as Unearned Revenue, a liability; does not affect A/R)
      • Ending Balance: "$52,000$14,800+$12,500=$49,700""\$52,000 - \$14,800 + \$12,500 = \$49,700"
  • Credit Sales Entries:
    • Sale to customer (e.g., CompStore): "Debit Accounts Receivable - CompStore, Credit Sales""\text{Debit Accounts Receivable - CompStore, Credit Sales}"
Uncollectible Accounts (Bad Debts)
  • Allowance Method: Follows the matching principle by estimating bad debts at the end of each period.
    • Percent of Sales Method: Estimates bad debt as a percentage of credit sales ($700,000×3%=$21,000\$700,000 \times 3\% = \$21,000).
    • Accounts Receivable Method: Estimates the Allowance for Doubtful Accounts balance via Aging of Receivables or a flat percentage of total A/R.
    • Aging Method Principle: The longer a receivable is past due, the lower the likelihood of collection.
    • Journal Entry for Write-off (Allowance Method):
      • "Debit Allowance for Doubtful Accounts, Credit Accounts Receivable""\text{Debit Allowance for Doubtful Accounts, Credit Accounts Receivable}"
      • Effect on total assets: No change (net realizable value remains the same).
    • Recovery of Write-off: Requires reversing the write-off and then recording the cash collection.
  • Direct Write-off Method: Recording the expense only when specific accounts are deemed uncollectible (Not GAAP compliant for most large firms).
    • Entry: "Debit Bad Debt Expense, Credit Accounts Receivable""\text{Debit Bad Debt Expense, Credit Accounts Receivable}"

INVENTORY SYSTEMS AND VALUATION

Inventory Systems
  • Perpetual Inventory System: Continuously updates inventory and Cost of Goods Sold (COGS) with each purchase and sale.
    • Recording a sale: Requires two entries:
      1. "Debit Cash/A/R, Credit Sales""\text{Debit Cash/A/R, Credit Sales}"
      2. "Debit COGS, Credit Inventory""\text{Debit COGS, Credit Inventory}"
  • Periodic Inventory System: Records purchases in a temporary account and updates inventory only at the end of the period via a physical count.
    • Recording a purchase: "Debit Purchases, Credit Cash/A/P""\text{Debit Purchases, Credit Cash/A/P}"
    • Recording a sale: "Debit Cash/A/R, Credit Sales""\text{Debit Cash/A/R, Credit Sales}" (No COGS entry is made at the time of sale).
  • COGS Equation (Periodic):
    • COGS=Beginning Inventory+PurchasesEnding Inventory\text{COGS} = \text{Beginning Inventory} + \text{Purchases} - \text{Ending Inventory}
Inventory Costing Methods
  • FIFO (First-In, First-Out): Assumes the oldest costs are transferred to COGS first; ending inventory is based on the most recent costs.
  • LIFO (Last-In, First-Out): Assumes the most recent costs are transferred to COGS first; ending inventory is based on the oldest costs.
    • Tax Advantage: LIFO often results in higher COGS and lower net income during periods of rising prices, reducing taxable income.
  • Weighted Average: Calculates a unit cost by dividing total cost of goods available for sale by total units available for sale.
    • Weighted Average Cost per Unit=Total CostTotal Units\text{Weighted Average Cost per Unit} = \frac{\text{Total Cost}}{\text{Total Units}}
  • Specific Identification: Identifies each item in ending inventory with a specific purchase and invoice.
Inventory Errors and Valuation Rules
  • Inventory Shrinkage: Loss of inventory due to theft, damage, or bookkeeping errors. Identified when the physical count is less than the ledger balance.
  • Lower of Cost or Market (LCM): Inventory must be reported at the lower of its historical cost or its current replacement cost (market value), supporting the Conservatism Principle.
  • Impact of Errors:
    • Understated Ending Inventory: Leads to overstated COGS and understated Net Income.
    • Overstated Ending Inventory: Leads to understated COGS and overstated Net Income.
Shipping and Ownership
  • FOB Shipping Point: Ownership transfers once the goods leave the seller's premises. The buyer pays freight-in (added to inventory cost\text{added to inventory cost}).
  • FOB Destination: Ownership transfers once goods arrive at the buyer's premises. The seller pays shipping/delivery expense.

INTERNAL CONTROL AND CASH MANAGEMENT

Principles of Internal Control
  • Identity: Policies and procedures designed to protect assets, ensure reliable accounting, and promote efficiency.
  • Limitations: Internal controls are NOT identical across companies; they must be tailored to specific needs.
  • Key Principles:
    • Establishing clear responsibilities (assigned to one person).
    • Maintaining adequate records.
    • Using technology (e.g., cash registers, time clocks).
    • Separation of duties (e.g., two people present when opening mail involving cash).
Cash and Cash Equivalents
  • Cash Equivalents: Short-term, highly liquid investments that are readily convertible to known cash amounts and are near maturity (typically within 3 months).
  • Cash Over and Short: An account used specifically to record discrepancies in the cash register where the physical cash does not match the recorded sales.
  • Petty Cash: Used for small payments.
    • Reimbursement involves debiting various expense accounts and crediting Cash (not the Petty Cash account itself).
Bank Reconciliation
  • Explains differences between the bank statement balance and the company's book balance.
  • Adjustments to Bank Balance:
    • Add: Deposits in transit.
    • Deduct: Outstanding checks.
  • Adjustments to Book Balance:
    • Add: Bank interest, EFT receipts.
    • Deduct: Bank service charges, NSF checks.
    • Example: A check written for $750\$750 but recorded as $768\$768 requires an addition of $18\$18 back to the book balance.

PLANT ASSETS, DEPRECIATION, AND INTANGIBLES

Plant Assets and Valuation
  • Characteristics: Used in operations, have useful lives exceeding one accounting period.
  • Cost Components: Includes invoice price, freight, assembly, and testing. It excludes financing/interest costs for natural resources.
  • Lump-Sum Purchase: Total cost is allocated based on relative appraised (market) values.
Depreciation Methods
  • Straight-Line: Annual Depreciation=CostSalvage ValueUseful Life\text{Annual Depreciation} = \frac{\text{Cost} - \text{Salvage Value}}{\text{Useful Life}}
  • Double-Declining Balance (DDB): An accelerated method.
    • Rate=2×(1Useful Life)\text{Rate} = 2 \times (\frac{1}{\text{Useful Life}})
    • Expense=Beginning Book Value×Rate\text{Expense} = \text{Beginning Book Value} \times \text{Rate}
  • Units-of-Production: Based on actual asset usage.
Natural Resources and Intangibles
  • Depletion: The process of allocating the cost of natural resources (e.g., timber, oil) to the periods in which they are extracted.
  • Amortization: The systematic allocation of the cost of intangible assets with limited lives (e.g., patents, copyrights).
  • Goodwill and Trademarks: Intangibles with indefinite lives; not subject to amortization but tested for impairment.
  • Book Value: The difference between the original cost and accumulated depreciation (CostAcc. Depr.\text{Cost} - \text{Acc. Depr.}).
Expenditures
  • Revenue Expenditures: Ordinary repairs that maintain normal operating condition (Expensed on the Income Statement\text{Expensed on the Income Statement}).
  • Capital Expenditures: Extraordinary repairs or additions that extend the asset's life or capacity (Capitalized on the Balance Sheet\text{Capitalized on the Balance Sheet}).

LIABILITIES AND PAYROLL

Current and Long-Term Liabilities
  • Known Liabilities: Measurable and certain obligations (e.g., A/P, Notes Payable).
  • Liability Characteristics: Present obligations, resulting from past events, requiring future sacrifice of assets or services.
  • Unearned Revenue: A liability created when cash is received in advance of providing service.
Notes Payable and Interest
  • Interest Formula: Interest=Principal×Annual Rate×Time (in years)\text{Interest} = \text{Principal} \times \text{Annual Rate} \times \text{Time (in years)}
  • Example: A 60-day, $5,000\$5,000 note at 12%12\%
    • Interest=$5,000×0.12×(60360)=$100\text{Interest} = \$5,000 \times 0.12 \times (\frac{60}{360}) = \$100
  • Total Maturity Value: Principal+Interest\text{Principal} + \text{Interest}
Bonds Payable
  • Bond Indenture: The legal contract identifying the rights and obligations of the issuer and bondholders.
  • Issuance Pricing:
    • At Par: Stated Rate == Market Rate.
    • At Premium: Stated Rate >> Market Rate. (Difference is credited to Premium on Bonds Payable).
    • At Discount: Stated Rate << Market Rate. (Difference is debited to Discount on Bonds Payable, a contra-liability).
  • Interest Tax Deductibility: Unlike dividends, bond interest is tax-deductible for the corporation.
Payroll Accounting
  • Gross Pay: Total earnings before deductions (Hours worked ×\times Hourly rate ±\pm Overtime).
    • 40hours×$25=$1,00040\, \text{hours} \times \$25 = \$1,000.
    • 6overtime hours×$37.50=$2256\, \text{overtime hours} \times \$37.50 = \$225.
    • Total Gross=$1,225\text{Total Gross} = \$1,225.
  • Net Pay: Gross pay minus all withholdings (Federal tax, Social Security, Medicare).

STOCKHOLDERS' EQUITY AND CORPORATIONS

Corporate Formation and Shares
  • Characteristics: Separate legal entity, limited liability for owners, continuous life.
  • Rights of Common Stockholders: Voting right, dividend right, liquidation right, and Preemptive Right (maintaining proportional ownership during new issuances).
  • Authorized vs. Issued vs. Outstanding:
    • Authorized: Maximum shares allowed to be sold.
    • Issued: Shares actually sold.
    • Outstanding: Issued shares currently held by investors (Issued minus Treasury Stock).
  • Par Value: An arbitrary value assigned per share by the corporate charter; represents the minimum legal capital.
Preferred Stock and Dividends
  • Preferred Stock: Has priority over common stock for dividends and liquidation assets.
  • Cumulative Preference: If dividends are missed, they accumulate and must be paid in the future before any common dividends.
  • Issuance at Premium: Excess over par is recorded as "Paid-in Capital in Excess of Par Value."
Retained Earnings and Dividends
  • Retained Earnings (RE): Cumulative net income minus net losses and cumulative dividends since inception.
    • Ending RE=Beginning RE+Net IncomeDividends\text{Ending RE} = \text{Beginning RE} + \text{Net Income} - \text{Dividends}
  • Cash Dividends: Reduce both Assets and Equity (Retained Earnings).
  • Stock Dividends: Transfer Retained Earnings to Paid-in Capital. They do NOT reduce total Equity or total Assets.

THE ACCOUNTING CYCLE AND FINANCIAL STATEMENTS

Accounting Principles and Assumptions
  • Going-Concern Assumption: The business will continue to operate indefinitely rather than being closed or sold.
  • Business Entity Assumption: A business is accounted for separately from its owner.
  • Cost Principle: Assets are recorded at their actual historical cost, not current market value.
  • Matching Principle (Expense Recognition): Record expenses in the same period as the revenues they generate.
  • Accrual Basis Accounting: Recording revenues when earned and expenses when incurred, regardless of cash flow timing.
The Closing Process
  • Temporary Accounts: Accounts that are closed to zero at year-end (Revenues, Expenses, Dividends/Withdrawals, Income Summary).
  • Permanent Accounts: Not closed; balances carry forward (Assets, Liabilities, Capital/Equity).
  • Income Summary: Used only during closing to summarize net income or loss before transferring the balance to RE/Capital.
  • Post-Closing Trial Balance: Verifies that total debits equal credits after all temporary accounts have been closed. Only permanent accounts appear here.
Financial Statements
  • Income Statement: Reports revenues and expenses for a period of time. Results in Net Income or Loss.
  • Statement of Retained Earnings (or Owner's Equity): Explains changes in the owners' stake over a period of time.
  • Balance Sheet: Lists assets, liabilities, and equity at a specific point in time.
  • Accounting Equation: Assets=Liabilities+Equity\text{Assets} = \text{Liabilities} + \text{Equity}
