One-sixth of the prepayment is consumed and one-fourth of the advance is earned; the remaining asset and liability carry the other portions forward.
This treats all cash as current-period expense and revenue despite five months of coverage and three milestones remaining.
The cash-date balances are recorded, but this omits the month-end consumption and performance adjustments.
This reverses the month-end account effects: consumption reduces the prepaid asset with a credit, and performance reduces the advance liability with a debit.
Answer: A
The $6,000 payment debits Prepaid Insurance and credits Cash; one of six months transfers $1,000 to Insurance Expense, leaving $5,000 prepaid. The $8,000 receipt debits Cash and credits Customer Advance; one of four milestones transfers $2,000 to Service Revenue, leaving a $6,000 liability. Cash is $15,000 minus $6,000 plus $8,000, or $17,000. Adjusted debit balances are $17,000 Cash, $5,000 Prepaid Insurance, and $1,000 Insurance Expense; credits are $15,000 Owners' Equity, $6,000 Customer Advance, and $2,000 Service Revenue. Each side totals $23,000.
