Comprehensive Notes on Periodicity, Accrual Basis, Revenue Recognition, Adjusting Entries, and Related Concepts

Periodicity Assumption

  • The periodicity assumption (a GAAP concept) holds that the economic life of a business can be divided into artificial time periods for reporting purposes. It is interpreted as: "the economic life of a business can be divided into artificial time periods". The other options are common accounting notions but do not define periodicity.
  • This underpins accrual accounting and how we prepare financial statements over intervals (months, quarters, years).

GAAP and Accrual Basis Accounting

  • GAAP = Generally Accepted Accounting Principles.
  • We follow accrual basis accounting under GAAP, not cash basis.
  • Core idea: revenue recognition depends on when the performance occurs, not when cash is received.
  • Revenue cannot be recognized unless the performance obligation is satisfied, even if cash is paid or received earlier or later.

Revenue Recognition under accrual accounting

  • Key rule: recognize revenue when the service or performance obligation is satisfied, not when cash is received.
  • Example: Conrad Window Cleaners provides cleaning services for $100 on June 30; customer pays on July 5.
    • Revenue recognition: June 30 (when service performed).
    • Accounts receivable (asset) is created when service is performed, representing money owed by the customer.
    • When cash is received on July 5, Accounts Receivable is swapped for Cash.
  • Accounts Receivable (AR) is an asset that will eventually become cash.
  • The process emphasizes that accrual accounting focuses on when the activity occurred, not when cash changes hands.
Steps to determine when revenue should be recognized (under accrual basis)

1) Identify whether a contract exists with the customer (an agreement to provide goods/services).
2) Within the contract, determine the performance obligations (may be more than one).
3) Determine the transaction price.
4) Allocate the transaction price to each performance obligation.
5) Recognize revenue as each performance obligation is satisfied.

Example: Season tickets (multiple performance obligations)

  • Season tickets to a football team: contract includes 10 games throughout the season.
  • Total transaction price: $10,000; there are 10 performance obligations (games).
  • Revenue recognized as each game occurs: $1,000 per game.
  • Until a specific game occurs, revenue associated with that game cannot be recognized.
  • This illustrates multiple performance obligations within one contract and the need to allocate the price accordingly.

Expense Recognition Principle (Matching Principle)

  • The matching principle requires recognizing expenses in the period in which the related revenues are earned (i.e., when the effort or cost contributed to revenue occurs).
  • Common expression: "let the expenses follow the revenues". Do not focus on cash timing; focus on when the revenue was earned.
  • Cash-basis accounting is not allowed under GAAP; it can misstate profitability because it ignores when the related economic activity occurs.
  • If the business pays an expense before revenue is earned or pays after revenue is earned, matching requires aligning the expense with the associated revenue.

Cash basis vs Accrual basis (illustrative comparison)

  • Scenario: A painting contractor incurs costs in year 1 (supplies, labor) and gets paid in year 2.
    • Cash basis: Year 1 records expenses when paid (loss of $50,000); Year 2 records revenue when cash is received (revenue $80,000); net income across years is distorted.
    • Accrual basis (GAAP): Recognize revenue when work is performed and recognize expenses in the period incurred, even if cash flows occur in a different period. This yields a more accurate reflection: e.g., Year 1 shows revenue recognized for work performed and related expenses; Year 2 shows any remaining activity and cash receipts.

Updating and Adjusting Entries (overview)

  • Adjusting entries are made to ensure financial statements reflect the true economic position at the end of the period.
  • All adjusting entries affect exactly one income statement item and one balance sheet item.
  • The adjusting process is part of the period-end close after initial trial balance and before financial statements.
  • Two major categories of adjusting entries: Deferrals and Accruals. (Depreciation is treated as a separate, recurring adjustment involving a contra-asset account.)
  • A common summary: adjusting entries ensure expenses are recognized when incurred and revenues are reported when earned.

Deferrals (cash before activity)

  • Prepaid expenses: cash paid before the service/use occurs; asset is reduced as benefit is consumed and an expense is recognized.
    • Examples: prepaid expenses such as supplies, rent, insurance, or advertising.
  • Unearned revenues: cash received before the service/product is delivered; a liability is created and revenue is recognized as the service is performed.

Accruals (activity before cash)

  • Accrued revenues: revenues earned but not yet billed/collected; create an asset (Accounts Receivable) and revenue.
  • Accrued expenses: expenses incurred but not yet paid; recognize expense and a liability (Accounts Payable).

Adjusting Entries: Deferrals in detail (deferral category examples)

  • Deferral: Prepaid expenses
    • Concept: We paid cash ahead of receiving the service or benefit.
    • Journal entry pattern: Debit an Expense; Credit the corresponding Asset (e.g., Supplies, Prepaid Insurance).
    • Example: Sierra Corporation purchases supplies for $2,500 on Oct 5. End of Oct, on-hand supplies = $1,000.
    • Supplies used: $2,500 − $1,000 = $1,500.
    • Adjusting entry: Debit Supplies Expense $1,500; Credit Supplies $1,500.
  • Deferral: Prepaid insurance
    • Concept: Pay insurance in advance; expense is recognized as time passes.
    • Example: On Oct 4, Sierra pays $600 for a 1-year policy. Monthly expense = $600 / 12 = $50.
    • At Oct 31 (one month expired): Debit Insurance Expense $50; Credit Prepaid Insurance $50.
    • End result: Remaining prepaid insurance = $550.
  • Depreciation (a cost allocation mechanism for PPE, not a cash deferral)
    • Concept: Allocate the cost of long-lived assets over their useful life; accumulated depreciation is a contra-asset account.
    • Journal entry pattern: Debit Depreciation Expense; Credit Accumulated Depreciation (a contra-asset).
    • Example: If a car costs $10,000 and has a 10-year life with straight-line depreciation (no residual value assumed here), annual depreciation would be extDepreciationperyear=10,00010=1,000.ext{Depreciation per year} = \frac{10{,}000}{10} = 1{,}000. Notes: depreciation is not about fair market value; it's about cost allocation and matching revenues with the use of the asset.
    • Book value after depreciation: extBookValue=extCost−extAccumulatedDepreciationext{Book Value} = ext{Cost} - ext{Accumulated Depreciation}
    • Land is not depreciated.

Adjusting Entries: Accruals in detail (accrual category examples)

  • Accrued revenues
    • Concept: Revenue earned but not yet billed/collected; recognize revenue and an asset (Accounts Receivable).
    • Example: Sierra Corporation received $1,200 on Oct 2 for advertising services to be completed by Dec 31; on Oct 31, $400 of services were performed.
    • Liability originally recorded as Unearned Service Revenue: $1,200.
    • Adjusting entry when $400 of services are performed: Debit Unearned Service Revenue $400; Credit Revenue $400.
    • Result: liability decreases to $800; revenue increases by $400.
  • Accrued expenses
    • Concept: Expenses incurred but not yet paid; recognize expense and a liability (Accounts Payable).
    • Typical entries mirror the deferral patterns but in the opposite direction (expense recognized before cash payment).

Sierra Corporation: Worked through Deferrals, Accruals, and Adjustments (illustrative examples)

  • Example 1: Prepaid expenses – supplies
    • Initial: Purchase $2,500 of supplies on Oct 5 (asset increases).
    • End of Oct: Supplies on hand = $1,000.
    • Used: $2,500 − $1,000 = $1,500.
    • Adjusting entry: Debit Supplies Expense $1,500; Credit Supplies $1,500.
  • Example 2: Prepaid insurance
    • Initial: $600 paid Oct 4 for a 12-month policy; asset increases (Prepaid Insurance).
    • Monthly expiration: $50.
    • Oct 31 adjustment: Debit Insurance Expense $50; Credit Prepaid Insurance $50.
    • Balance after adjustment: Prepaid Insurance = $550.
  • Example 3: Depreciation on equipment
    • Depreciation expense recognized periodically; accumulated depreciation increases (contra-asset).
    • Journal entry pattern: Debit Depreciation Expense; Credit Accumulated Depreciation.
    • Example: If depreciation is $200 per month, Debit Depreciation Expense $200; Credit Accumulated Depreciation $200.
    • Book value concept: Cost minus accumulated depreciation; equipment cost remains on asset side, but accumulated depreciation shows the total depreciation against it.
  • Example 4: Unearned service revenue (revenue recognition after performance)
    • Initial: Sierra receives $4,000 on Oct for services to be performed; uneared revenue liability recorded.
    • Adjustment: When $4,000 of services are performed in March, debit Unearned Service Revenue $4,000; Credit Revenue $4,000.
    • Result: Liability decreases, Revenue increases, reflecting earned revenue and reduced obligation.

Recap: True/False style concepts from the lecture

  • Statement: Events that change a company’s financial statements are recorded in the periods in which the events occur. True under accrual accounting; revenue is recognized in the period when services are performed (the performance occurs).
  • Statement: Expense recognition requires recognizing expenses in the period in which they are paid. This is false under GAAP; expense recognition follows the matching principle (in the period incurred or in the period that relates to the revenue).
  • Statement: A simple rule for recognizing expenses is to let the revenue follow the expenses. This is false; the correct rule is to let the expenses follow the revenue (i.e., expenses should be recognized in the same period as the related revenue).
  • Overall: Under accrual basis accounting, we record transactions in the period in which the activities occur, not necessarily when cash changes hands.

Final takeaway

  • Accrual accounting aligns revenue with the period in which the performance occurs and aligns expenses with the revenues they help generate (matching).
  • Deferrals and accruals are the primary mechanisms for end-of-period adjustments to ensure accurate financial statements.
  • Depreciation uses accumulated depreciation to reflect asset usage without reducing the asset’s historical cost directly, preserving the original cost while showing the cost allocation over time.
  • Cash basis is simple but not GAAP-compliant; it can distort timing of revenue and expense recognition.
