What is the difference between an assurance warranty and a service-type warranty under IFRS 15?

Under IFRS 15 (and ASC 606), warranties are classified as either assurance-type or service-type, and the accounting treatment is completely different.

Assurance Warranty:

This is a promise that the product will function as specified. It is not a separate performance obligation — it is simply a quality guarantee.

Characteristics:

• Required by law or standard industry practice
• Covers defects existing at the time of sale
• Customer has no option to purchase it separately
• Short duration (typically matches legal requirement)

Accounting: Accrue a warranty provision (expense + liability) at the time of sale using estimated repair/replacement costs. Revenue is unaffected — the full transaction price is allocated to the product.

Service-Type Warranty:

This provides a service beyond the basic assurance — it is essentially an extended warranty or maintenance contract. It is a separate performance obligation.

Characteristics:

• Customer has the option to purchase separately
• Covers events occurring after the sale (wear and tear, accidental damage)
• Extends beyond the standard assurance period
• Provides coverage not required by law

Accounting: Allocate a portion of the transaction price to the service-type warranty and recognize that revenue over the warranty service period.

Worked Example:

Starfield Electronics sells a commercial printer for $12,000 with:

• A standard 1-year warranty against manufacturing defects (assurance)
• An optional 3-year extended warranty for $1,800 (service-type)

Total cash received: $13,800

Revenue allocation:

Standard warranty provision: Starfield estimates $350 in expected repair costs during the 1-year assurance period. At the time of sale:

• Dr. Warranty Expense $350
• Cr. Warranty Provision (Liability) $350

Balance sheet at sale date:

• Revenue recognized: $12,000 (printer)
• Contract liability (deferred revenue): $1,800 (extended warranty)
• Warranty provision: $350 (assurance warranty estimated costs)

What if the warranty is bundled and the customer cannot buy it separately?

If the seller includes the extended warranty in the price and the customer has no option to purchase the product without it, you must still assess whether the warranty provides a service beyond assurance. Indicators that it is service-type even when bundled:

• The warranty period far exceeds the standard for the industry
• The warranty covers user-caused damage (not just defects)
• The seller regularly sells similar warranties separately to other customers

Exam tip: The CFA Level II exam will describe a warranty arrangement and ask whether it is a separate performance obligation. Look for the key words: "beyond assuring agreed-upon specifications" means service-type. "Meets agreed-upon specifications" means assurance.
