On October 1, 2014, Lyndon, Inc. purchased a computer system for $86,000 from AIT Systems. The computer system had an estimated life of 5 years and residual value of $3,000. Lyndon paid $2,820 for shipping and insurance and hired an engineering company to install and set up the computer system for $7,500. AIT asked for $20,000 cash payment immediately; in addition, AIT accepted a one-year note payable of $50,000 plus 6% interest due on September 30, 2015. The remaining $16,000 is due in 30 days; however, AIT allowed a 2% discount on this $16,000 if Lyndon makes a payment by October 15. Lyndon paid the invoice on October 31. Lyndon uses the straight-line depreciation method.
On July 1, 2016, Lyndon replaced a hard drive costing $12,000 and, as a result, the useful life of the computer system increased by 2 years.
On January 10, 2017, the computer system experienced irreparable damage. Lyndon made a claim to the insurance company. Subsequently, Lyndon received $40,000 cash on January 31, 2017.
