Proved reserves are evaluated in accordance with SEC regulations. 3. Probable reserves are the sum of proved reserves and probable reserves evaluated in accordance with SPE/WPC/AAPG/SPEE guideline Petroleum Resources Management System 7 (PRMS) approved in March 7 after deduction of proved reserves evaluated in accordance with SEC regulations. Probable reserves as of March 31, 7 are evaluated in accordance with the guideline established by SPE and WPC (1997 SPE/WPC). Probable reserves include reserves of bitumen. 4. Possible reserves are evaluated in accordance with PRMS. Possible reserves also include reserves of bitumen. 5. Disclosure details for the standardized measure of discounted future net cash flows related to proved oil and gas reserves and movements during the fiscal year under review are presented in accordance with the rules and regulations stipulated by the U.S. Financial Accounting Standards Board, and are reported in accordance with Accounting Standard Codification Topic 932 Extractive activities Oil and. In calculating the standardized measure of discounted future net cash flows, the period average of oil and gas prices at the first day of each month as well as period-end costs are applied to the estimated annual future production from proved reserves to determine future cash inflows. Future development costs are estimated based upon constant price assumptions and assume the continuation of existing economic, operating and regulatory conditions. Future income taxes are calculated by applying the period-end statutory rate to estimated future pretax cash flows after provision for taxes on the cost of oil and natural gas properties based upon existing laws and regulations. The discount is computed by applying a 1% discount factor to the estimated future net cash flows. 6. includes condensate and LPG. 7. The exchange rates as of March 31, 7, 8, 9, 1, 11, 12, 13, 14, 15 and 16 are the TTM rate of 118.9, 1., 98.26, 93.4, 83.15, 82.14, 93.99, 12.92, 1.27 and 112.69 per U.S.$, respectively. 8.
