This document discusses Accounting Standard 2 and 6. AS 2 provides guidance on determining inventory costs and valuation. It specifies methods for computing inventory costs and determining the amount to report in financial statements. AS 6 deals with depreciation accounting. It applies to all depreciable assets except certain specified items. AS 6 requires that the depreciable amount of an asset be allocated systematically over its useful life and that the depreciation method be applied consistently over time. Both standards provide principles for uniform accounting practices related to inventory valuation and depreciation.
