Note: 

The Investment Manager is charged with the responsibility of valuing the assets held by REL and the Partnership. The Partnership has directed that securities and instruments be valued at their fair value. REL's valuation policy follows the IFRS accounting standards and IPEV Valuation Guidelines. Riverstone values each underlying investment in accordance with the Riverstone private fund valuation policy, the IFRS accounting standards and IPEV Valuation Guidelines. The value of REL's portion of that investment is derived by multiplying its ownership percentage by the value of the underlying investment. If there is any divergence between the Riverstone private fund valuation policy and REL's valuation policy, the Partnership's proportion of the total holding will follow REL's valuation policy and the Fund V or Fund VI proportion will follow the Riverstone private fund valuation policy. Valuations determined by Riverstone are disclosed quarterly to investors.

Riverstone values its investments using common industry valuation techniques, including comparable public market valuation, comparable merger and acquisition transaction valuation, and discounted cash flow valuation.

For development-type investments, Riverstone also considers the recognition of appreciation of subsequent financing rounds, if any, or if subsequent financing rounds are below original cost, the investment is valued at the "down round". For those early stage privately held companies where there are other indicators of a decline in the value of the investment, Riverstone will value the investment accordingly even in the absence of a subsequent financing round.

Riverstone reviews the valuations on a quarterly basis with the Riverstone investment committee as part of the valuation process. Ernst & Young LLP attends the valuation review meetings that are relevant to the Company as part of their statutory audit process.
