Information for month-end adjustments follows:

December 31	One month of the 12-month, $3,720 insurance policy is expired by December 31. This leaves $3,410 not yet expired.
December 31	A physical count of supplies on December 31 shows that only $1,210 of supplies remain of the $2,020 supplies purchased.
December 31	The $6,240 of equipment purchased at the beginning of December has a useful life of 5 years and will be worth nothing at the end of 5 years (60 months). The business uses straight-line depreciation to allocate the $6,240 net cost over 60 months. On December 31, 1 month of depreciation must be recorded.
December 31	The business agreed on December 23 to provide a 4-week training service to a customer for a fixed fee of $1,640 paid in advance. By December 31, the business has provided 1 of the 4 weeks of services and earned one-fourth of the fee. No revenue is yet recorded.
December 31	On December 31, wages of $610 are owed to a part-time employee for work done over the past 3 weeks. Those wages are not yet paid or recorded.
December 31	The business agreed to provide 6 weeks of training services to a customer for a fee of $4,260, or $710 per week. The customer agrees to pay the full $4,260 at the end of 6 weeks when services are complete. By December 31, 2 weeks of services have been provided, but the business has not yet billed the customer or recorded the 2 weeks of services provided.
