5.38 Solomon Pty Ltd is a highly successful, closely held Brisbane company that manufactures and assembles motor vehicle speciality parts that are sold in auto parts stores. Sales and profits have expanded rapidly in the past few years and the prospects for future years are every bit as encouraging. In fact, the Solomon brothers are currently considering either selling out to a large company or going public to obtain additional capital. The company originated in 1964 when Frank Solomon decided to manufacture tooled parts. In 1979, the company changed over to the auto parts business. Fortunately, it has never been necessary to expand the facilities, but space problems have recently become severe and expanded facilities will be necessary. Land and building costs in Brisbane are currently extremely inflated. Management has always relied on you for help in its problems because the financial controller is sales-orientated and has little background in the controllership function. Salaries of all officers have been fairly modes in order to reinvest earnings in future growth. In fact, the company is oriented towards long-run wealth of the brothers more than towards short-run profit. The brothers have all their personal wealth invested in the firm. A major reason for the success of Solomon has been the small but excellent sales force. The sales policy is to sell to small auto shops at high prices. This policy is responsible for fairly significant credit losses, but the profit margin is high and the results have been very successful. The firm has every intention of continuing this policy in the future. Your firm has been auditing Solomon since 1974 and you have been on the job for the past three years. The company has excellent internal controls and has always been cooperative. In recent years Solomon has attempted to keep net profit at a high level because of borrowing needs and future sellout possibilities. Overall, the company has always been pleasant to deal with and willing to help in any way possible. There have never been any major audit adjustments and an unmodified opinion has always been issued. In the current year you have completed the test of the sales and collection area. The tests of controls and substantive test of transactions for sales and sales returns and allowances were excellent, and an extensive confirmation yielded no material misstatements. You have carefully reviewed the cutoff for sales and for sales returns and allowances and found these to be excellent. All recorded bad debts appear reasonable, and a review of the aged trial balance indicated that conditions seem about the same as in past years.
