Annotation of standard text ASTM ADJE091717-EA :

The Adjunct contains three sets of discount factor tables. The first set of tables presents values for the following six discount factors defined in Table 1: (1) Single Compound Amount (SCA); (2) Single Present-Value (SPV); (3) Uniform Capital-Recovery (UCR); (4) Uniform Present-Value (UPV); (5) Uniform Sinking-Fund (USF); and (6) Uniform Compound Amount (UCA). The second set of tables presents values for the modified UPV discount factor (UPV*) where a series of payments is increasing from period to period at a given rate, rather than remaining constant over the entire study period as is the case for the UPV. The third set of tables presents values for the modified SPV discount factor (SPV*) for determining the present value of a single payment occurring at a future point in time when that payment is specified in base-time prices but is expected to increase in value over time at a specified periodic rate. The factors for all three sets of tables have been calculated to four significant digits. The tables cover discount rates from 1 to 25% in 1% increments, and for time periods from 1 to 40 years in 1 year increments. The Adjunct contains an introductory section where each discount factor is described. The description includes an equation that uniquely defines the factor; terms used in the equation for that factor are also defined. Where appropriate, a sample calculation using a discount factor is provided. Tables 1 through 25 present discount factors for each of the six discounting operations defined in Table 1. The formula for each discount factor appears at the top of each of the tables. Each table presents discount factors for a specified discount rate. The UPV* discount factors are provided in Tables U-1 through U-25. Each table presents discount factors for a specified discount rate and rates of price increase ranging from 1 to 20 % (even values only above 10%). The SPV* discount factors are provided in Tables S-1 through S-25. Each table presents discount factors for a specified discount rate and rates of price increase ranging from 1 to 20% (even values only above 10 %).
