2. The SPES composite’s investment multiple (TVPI) is closest to:
选项：
A. 0.13.
B. 0.86.
C. 1.12.
解释：
The GIPS Glossary defines the TVPI (real estate and private equity) as "total value divided by since inception paid-in capital." The GIPS Glossary defines Total Value (real estate and private equity) as "residual value plus distributions". Using the data given in Exhibit I, the simplest way to find TVPI is to add RVPI and DPI. The calculation is: 0.99 + 0.13 = 1.12. Alternately, one can multiply the monetary amount of paid-in capital by RVPI to determine the residual value, add it to cumulative distributions, and divide the sum by paid-in capital. In this approach, the calculation is [(20 ×0.99) + 2.5]/20 = 1.12. (See Section 3.15 of the reading.)
