II. Lecture Notes

1. Adjustment for office supplies(1) Why make adjustments at the end of accounting period/month?

It is not practical to make journal entries every few minutes/every day as the supplies are used.

Example: the consumption of chalk, ink or memo pad Only make an estimate or take a physical inventory of the supplies

remaining on hand at the end of the period; The “missing” supplies are assumed to have been used.

(2) An illustration Bought memo pads in cash, 500 Yuan

Office supplies (memo pads) 500Cash 500

Taking a physical inventory/or make an estimate at the end of the period200 Yuan of supplies is left.Office supplies (memo pads) expense 300

(1) Inventory systemsA. Perpetual inventory system

Purchases of merchandise are recorded by debiting the Merchandise Inventory account.Example: Beginning inventory (books @20 Yuan each) 2 000 Yuan Bought 100 books at 20 Yuan each

Merchandise Inventory + -

Beginning bal. 2000 2000

As the goods are sold, two entries are needed: one to recognize the revenue earned, and the second to transfer the cost of the goods out of inventory (into cost of goods sold)Example: Sold 20 books for cash at 25 Yuan each

Cash Sales + - - +

500 500

Merchandise inventory Cost of goods sold + - + - Beginning bal. 2000 400 400 2000

The basic characteristic of the perpetual inventory system is that the inventory account is continuously updated for all purchases and sales of merchandise.

Taking a physical inventoryBeginning inventory + purchases – cost of goods sold = Ending inventory

Who uses perpetual inventory system?--- Most businesses use perpetual inventory system in accounting for

products with a high per-unit cost but low sales volume, such as automobiles, heavy machinery, jewelry, home appliances, electronic equipment, etc.

--- Almost all manufacturing companies use perpetual inventory system.

--- In the days when all accounting records were maintained by hand, businesses that sold many types of low-cost products could not use this system. (Example: Wal-Mart could not use this system when it kept its accounts by hand)

--- With today’s point-of-sale terminals and bar-coded merchandise, even high-volume retailers like Wal-Mart and Trust-Mart can use this system.

--- Advances in technology (computer-aided accounting) extend the use of perpetual inventory system to more businesses and more types of products.

B. Periodic inventory system Acquisition of merchandise is recorded by debiting the Purchase

account. Merchandise inventory Purchases + - + - 2000 2000

8-2

The merchandise inventory account is brought up to date only at the end of the accounting period when a physical inventory is taken.

Beginning inventory + Purchases – ending inventory = cost of goods sold

Used when the need for current information about inventories and sales does not justify the cost of maintaining a perpetual system.

Businesses that sell many low-cost items and have manual accounting systems have to use periodic system.
