1. This column refers to Hulten-Wykoff categories (Hulten and Wykoff 1981b; Wykoff and Hulten 1979). Type A assets are types of assets for which Hulten and Wykoff specifically estimated age-price profiles. Type B assets are those for which they used empirical research by others and their judgement to estimate the depreciation rate. Type C assets are assets for which they estimated an average declining-balance rate from data for all type A and B assets.
2. The depreciation rate for this type of asset is not used for computers and peripheral equipment. Depreciation rates for these assets are taken from Oliner as described in the text.
3. The declining-balance rate is from the Hulten-Wykoff communications equipment aggregate.
4. Instruments and other private nonresidential equipment, called producer durable equipment by Hulten-Wykoff, are classified by them as type C but appear to be type B as they were given a declining-balance rate of 1.6203.
5. The declining-balance rate is from the Hulten-Wykoff other producer durable equipment aggregate.
6. The depreciation rates for nuclear fuel are based on a straight-line rate pattern and a Winfrey retirement pattern.
7. The declining-balance rate is from the Hulten-Wykoff fabricated metal products aggregate.
8. The declining-balance rate is from the Hulten-Wykoff engines and turbines aggregate.
9. The depreciation rate and service life listed apply to nonmanufacturing industries; the service lives and depreciation rates used for manufacturing industries differ by industry. The Hulten-Wykoff type of asset listed applies to all industries.
10. The declining-balance rate is from the Hulten-Wykoff trucks, buses, and truck trailer aggregate.
11. Depreciation rates for autos are derived from data on new- and used-auto prices.
12. The declining-balance rate is from the Hulten-Wykoff furniture and fixtures aggregate.
13. The declining-balance rate is from the Hulten-Wykoff tractors aggregate.
14. The declining-balance rate is from the Hulten-Wykoff service industry machinery aggregate.
15. The declining-balance rate is set to the Hulten-Wykoff producer durable equipment default.
16. The declining-balance rate is from the Hulten-Wykoff electrical equipment (not elsewhere classified) aggregate.
17. The declining-balance rate is from the Hulten-Wykoff commercial aggregate.
18. The declining-balance rate is from the Hulten-Wykoff other private nonresidential structures aggregate, which consists of buildings used primarily for social and recreational activities and buildings not elsewhere classified.
19. The declining-balance rate is from the Hulten-Wykoff public utilities aggregate.
20. The declining-balance rate is set to the Hulten-Wykoff private nonresidential structures default.
21. The declining-balance rate is from the Hulten-Wykoff mining exploration, shafts, and wells aggregate.
22. The declining-balance rate is from the Hulten-Wykoff other private nonresidential structures aggregate, which consists of streets, dams and reservoirs, and sewer and water facilities.
23. The declining-balance rate is set to the Hulten-Wykoff producer durable equipment default.
24. For all consumer durables except for motor vehicles and parts and computing equipment, the declining-balance rate is set to the Hulten-Wykoff producer durable equipment default.
25. The corresponding Hulten-Wykoff consumer durables category is other.
26. Depreciation rates for computers and peripheral equipment are taken from Oliner as described in the text of the article. The information listed applies to video and audio products and musical instruments. The corresponding Hulten-Wykoff aggregate is radio and television receivers, recorders, and musical instruments. Radio and television receivers, recorders, and musical instruments are classified by Hulten-Wykoff as type B but are indistinguishable from type C as their declining-balance rate is 1.65.
27. The corresponding Hulten-Wykoff consumer durables category is wheel goods, durable toys, sports equipment.
28. The declining-balance rate is from the Hulten-Wykoff motor vehicles and parts aggregate. The declining-balance rate for this category is calculated under the assumption that the service life for consumer durables motor vehicles and parts is equal to the service life for producer durable equipment autos previously used by BEA.
29. For most government nonresidential equipment, the declining-balance rate is set to the Hulten-Wykoff producer durable equipment default. Where possible, the rate is set equal to the rate used for comparable equipment in the private sector.
30. Missiles are depreciated using straight-line patterns of depreciation and a Winfrey retirement pattern.
31. Depreciation rates for government-owned autos are derived from data on autos that are privately owned.
32. Depreciation rates for these assets are taken from Oliner as described in the text of the article.
33. For all government nonresidential structures, the declining-balance rate is set to the Hulten-Wykoff private nonresidential structures default.
