ABSTRACT 

This research work was conducted on with special reference to the impact inventoryvaluation methods has on financial report statements of manufacturing companies. For a longtime now the Accounting profession has not been able to come up with any particular technique or method to be used uniformly in valuing inventory. This research work examined if the method used was as a result ofthe prevailing economic circumstances. A survey research design was adopted for the study; data collected weregotten from both the primary and secondary sources. An infinite population of over 3000 was used and a finite population of 220. Three hypotheses were tested at 5 percent level of significance. Tables and percentages were employed to answer the questionnaires while the statistical regression coefficient analysis and Z- test were used to test the hypotheses. It was found amongst others that the prevailing economic parameter influences the decision of choice of inventory valuation method used. The Accounting professional bodies should try as much as possible to adopt a particular method of inventory valuation and the weighted average method was recommended as a method that can withstand any economic challenges.

1.0 INTRODUCTION 

1.1BACKGROUND OF THE STUDY 

 Inventory valuation allows companies to provide a monetary value for items that make up their inventory (stock). 

 Inventories are usually the largest current asset of a business and are as important as funds (cash). It is a form of fund tied up in assets (current assets). It‟s proper or accurate measurement or valuation cannot be overlooked as it forms a greater percentage of an enterprise‟s current assets in particular and a total asset in general. For manufacturing companies, inventories usually represent approximately 20 to 60 percent (%) of their assets. If inventory is not properly valued, it may result that expenses and revenue may as well not be properly matched and a company could make poor business decisions that will affect the company‟s profit. It is essential the way assets are valued because it could be attributable to the numerous benefits which an organization stands to gain by keeping an accurately valued stock that meet shareholders needs, demands for financial information and also the relevant specification of a particular organization. However, it will be a waste of time if the record accuracy is poor. 

 Inventory in manufacturing company or concern comprises of the following components: 

Raw materials inventory 

Work- in- progress (semi- finished goods) inventory 

Finished goods inventory 

 These components show the relationship between production and sales, and it enables an organization to offer better service to its customers at a reasonable price. 

 However, the technique or method used in the valuation of inventories varies and the values placed on inventories vary in time with the prevailing economic parameters (inflation, deflation or static economy) and it can also be influenced by the management policy of the organization. For instance, if the objective of an enterprise is that of profit maximization, it may result to the use of a particular method so as to disclose lower profit, thereby using excess fund at its disposal to expand its operations. This type of organization may discard other methods of valuing inventories in favour of the method that suit it objectives. 

 According to Nwoha (2006:69), no area of accounting has produced wider difference in practice than the computation of amount at which inventories (stocks) and work-in-progress as stated in financial account.
