Auto Parts, Inc. (the Company) manufactures automobile subassemblies marketed primarily to the large U.S. automakers. The publicly held Companys unaudited financial statements for the year ended December 31, 2018, reflect total assets of $56 million, total revenues of approximately $73 million, and pre-tax income of $6 million. The Companys audited financial statements for the year ended December 31, 2017, reflected total assets of $47 million, total revenues of approximately $60 million, and pre-tax income of $5 million. Earnings per share have increased steadily over the past five years, with a cumulative return of 140% over that period. During 2018, the Company significantly expanded its plant and fixed asset spending to accommodate increased orders received by its brake valve division. The company also accumulated significant levels of tooling supplies, which primarily consist of drill bits and machine parts utilized in the manufacturing process. The nature of the tooling supplies is such that the parts wear out relatively quickly and require continual replacement. In prior years, the Company expensed tooling supplies as they were purchased. However, at the beginning of 2018 the controller and chief financial officer (CFO) determined that capitalization of the tooling supplies would be the preferable method of accounting.The Company changed its accounting policy accordingly and began to include the tooling supplies in other current assets until the supplies are placed into service, at which time the Company enters a journal entry to remove the assets and record the costs of the used supplies as an expense. During the prior year, 2017, the Company incurred roughly $650,000 of tooling expense and held approximately $35,000 of the tooling supplies on hand at year-end. The on-hand supplies were not included in assets on Auto Parts balance sheet at December 31, 2017. The amount of supplies on hand at December 31, 2016 was trivial. In 2018 the Company purchased $1,330,000 of tooling supplies, of which the company used $1,000,000 during the year (in addition to the approximately $35,000 on hand at the beginning of the year). The increase of tooling supplies at year-end reflects the companys belief that prices would rise on the supplies in the first or second quarter of 2019. As such, the unaudited financial statements for the year ended December 31, 2018 reflect $1,000,000 of tooling expense on the income statement and $330,000 of tooling supplies as current assets on the balance sheet. The approximately $35,000 of tooling supplies on-hand at the end of last year were not included in the $1,000,000 tooling expense recorded in 2018 because those costs were expensed in 2017 under the old accounting policy. Because your accounting firm serves as external auditor for Auto Parts, the CFO and the controller asked your firm for advice on whether the Company would be required to account for and disclose the accounting policy change as a change in accounting principle, a change in estimate, or an error correction. In the clients opinion, the change is not material to the financial statements and, therefore, would not require disclosure in the 2018 financial statements. The client strongly prefers to not make any disclosure related to the policy change, as such the 2017 comparative statements would not be adjusted and the 2018 statements would simply reflect the new policy (i.e., in 2018 there would be a decrease in expense and increase in other current assets relative to the prior accounting policy) without the added attention of a disclosure. REQUIRED [1] Describe whether you agree that capitalization of the tooling supplies is the preferable method of accounting for Auto Parts, Inc. [2] In general, how do auditors develop an estimate of financial statement materiality? For Auto Parts, Inc., what is your estimate of financial statement materiality? Are there qualitative factors that might impact your decision about the materiality of the accounting treatment and the related disclosure? [3] Assuming the policy change is considered material, how should it be reported and disclosed in the 2018 financial statements and what would be the effect, if any, of the accounting change on the auditors report? [4] Do you concur with managements assessment that the accounting change is immaterial and, therefore, requires no disclosure? Why or why not
