5.	INTANGIBLES AND OTHER ASSETS

Intangible amounts have been impacted by the Company’s change in accounting method for the treatment of external patent and trademark costs. The Company no longer capitalizes external legal, filing, and continuation or annuity fees associated with patent and trademark applications. Under the current method of accounting, these types of external patent-related costs are expensed as incurred and classified as general and administrative expenses in the Company’s condensed consolidated statement of income consistent with the treatment of internal legal expenses. Costs associated with purchased patents and other purchased intangible assets continue to be capitalized as incurred. See Note 1 to the condensed consolidated financial statements for additional information regarding this change in accounting method.
