Final answer:
The adjusting entry for Streep Factory's estimated future warranty claims of $400,000 related to 2014 sales is a debit to Warranty Expense and a credit to Warranty Liability for the same amount.
Step-by-step explanation:
When a company like Streep Factory sells a product with a warranty, it is essentially promising to incur future expenses related to servicing warranty claims. In 2014, Streep Factory spent $70,000 on servicing warranty claims. However, they estimate that an additional $400,000 will be spent in the future related to 2014 sales. The adjusting entry on December 31 would reflect this estimated liability.
Here's the adjusting entry for December 31:
Warranty Expense $400,000
Warranty Liability $400,000
This entry increases the warranty expense for the estimated future costs and records a corresponding liability because the company has an obligation to service future warranty claims.
