Yes. It will only affect the asset portion of the company's balance sheet.
When the company buys the one-year insurance policy, the journal entries will be:
Debit Credit
Prepaid insurance 1,000
Cash 1,000
When the insurance expires after a year, the journal entries will be:
Insurance Expense 1,000
Prepaid Insurance 1,000
Note:
Prepaid Insurance and Cash are both found in the assets section of the balance sheet.
Insurance Expense is found in the Income statement of the company and not in the balance sheet.
