1. (Matching Principle) Accountants try to prepare income statements that are as accurate as possible. A basic requirement in preparing accurate income statements is to match costs against revenues properly. Proper matching of costs against revenues requires that costs resulting from typical business operations be recognized in the period in which they expired. 

(a) List three criteria that can be used to determine whether such costs should appear as charges in the income statement for the current period.

(b) As generally presented in financial statements, the following items or procedures have been criticized as improperly matching costs with revenues. Briefly discuss each item from the viewpoint of matching costs with revenues and suggest corrective or alternative means of presenting the financial information.

(1) Receiving and handling costs.

(2) Valuation of inventories at the lower of cost or market.

(3) Cash discounts on purchases.
