Study Notes on Chapter Four and Five: Perpetual Inventory System

Chapter Four Summary

Transportation Costs and Shipping Terms

  • FOB Shipping Point
    • Definition: The title of merchandise is transferred to the buyer at the shipping point.
    • Implications:
    • The buyer owns the goods during transit.
    • The buyer is responsible for shipping costs.
  • FOB Destination
    • Definition: The title of merchandise is transferred to the buyer at the destination point.
    • Implications:
    • The seller owns the goods during transit.
    • The seller pays for shipping costs.

Accounting for Shipping Costs

  • When goods are purchased at FOB shipping point:
    • The buyer must pay for shipping.
    • The shipping cost increases the cost of the inventory.
    • Recorded in the inventory account, affecting cash flow.
  • Example:
    • Merchandise inventory purchased for $500:
    • Accounts Payable will increase by $500.

Accounts Payable and Cash Transactions

  • When returning items:
    • Debit to Accounts Payable equals the amount returned.
    • Example entry for returning $50 worth:
      • Credit Merchandise Inventory by $50.
  • Purchase discounts:
    • Apply discount to total accounts payable.
    • Percentage of discount should be applied to the balance owed.
    • Example:
    • Total due after accounting for returns and discounts is $450.
    • Discount of $20 applied results in payment of $430.
    • Debit Accounts Payable to clear the balance.
    • Credit Merchandise Inventory to reflect the purchase discount.

Key Points on Inventory Accounting

  • Always credit accounts payable when incurring a liability or receiving inventory.
  • When goods are sold, you must make two sets of journal entries:
    1. For sales revenue.
    2. For reducing inventory and acknowledging cost of goods sold.
  • Cost of Goods Sold (COGS) is considered an expense; it should always have a debit balance, reflecting its nature as a cost.

Sales Transactions Under Perpetual Accounting

  • Requirement for two journal entries:
    • First entry for sales revenue (debit Accounts Receivable, credit Sales Revenue).
    • Second entry for adjusting inventory (debit Cost of Goods Sold, credit Merchandise Inventory).
  • Example:
    • Selling goods on credit for $1,000.
    • COGS entry relates to the cost of the sold items.
  • Sales discounts provided within a discount period (usually 10 days) allow customers to pay less if they pay early.
    • Calculate discount from the Accounts Receivable balance.

Sales Returns and Allowances

  • If a customer returns a product:
    • Flip the revenue journal entry:
    • Debit Sales Returns and Allowances, credit Accounts Receivable.
    • When products are returned:
    • Increase inventory: Debit Merchandise Inventory, credit COGS.
  • Tracking returns helps in managerial decision-making regarding product quality.

Summary of Inventory Management Under Perpetual System

  • Purchases increase inventory.
  • Returns decrease accounts payable and inventory.
  • Sales decrease inventory and increase cash flow via sales revenue.
  • Perpetual systems require constant updates to accounts to reflect real-time inventory levels.

Introduction to Periodic Inventory System

  • Periodic systems do not update inventory accounts throughout the period.
  • Inventory is counted at the end of the period.
  • Unique accounts for purchases, purchase returns, and discounts are used instead of direct inventory accounts.
    • Example:
    • Use "Purchases" instead of "Merchandise Inventory" when recording inventory purchases.
  • COGS is calculated at the end based on physical inventory counts:
    \text{COGS} = \text{Beginning Inventory} + \text{Net Purchases} - \text{Ending Inventory}

Multi-Step Income Statement

  • Divides income statement into revenue and expenses.
  • Clearly separated operating expenses:
    • Selling expenses and general/admin expenses.
  • Gross profit is calculated as:
    \text{Gross Profit} = \text{Total Revenue} - \text{COGS}
  • External benchmarking (comparing competitors’ gross profit ratios) aids in operational efficiency and profitability analysis.

Inventory Costing Methods

  • Four methods discussed:
    1. Specific Identification
    2. FIFO (First In, First Out)
    3. LIFO (Last In, First Out)
    4. Weighted Average Cost
  • Impact of these methods on COGS and ending inventory calculations:
    • FIFO sells oldest inventory first, LIFO sells newest first, weighted average uses an average of costs.
  • Example for Gas Station:
    • If purchasing prices fluctuate, revenue recognition may become complex without clear identification of cost layers for inventory sold.
