Major account classification of expenditures for property items including land, buildings and equipment. Further guidance for determining the proper classification can be found in the University of Alaska Accounting and Administrative Manual, Section 100 A-25. Buildings have a value of $100,000 or more and an expected useful life of greater than fifteen years. Equipment items have a value of $5,000 or more and an expected life of one year or longer. Building costs include structural additions, nonstructural improvements, field equipment (either added or replaced) and related freight. Equipment is defined as tangible, nonexpendable personal property. Equipment costs include the related freight, postage and installation charges. Entries for budget, payroll or accounting purposes may not be made to this account code.
