(formerly Bombay Stock Exchange (“BSE”) announced their strategic partnership to calculate, disseminate, and license the widely followed BSE suite of indices. Highlights The S&P BSE SENSEX Gold Hedged Index and S&P BSE SENSEX Dynamic Gold Hedged Index seek to simulate the returns of an investment strategy which is long the S&P BSE SENSEX and hedged against changes in the Indian rupee versus gold. The indices are calculated by hedging the beginning-of-period S&P BSE SENSEX total return index values using rolling Multi Commodity Exchange (MCX) Gold Mini futures contracts. The hedge only protects against adverse movements in the relative value of the Indian rupee, as expressed in the rupee price of gold. Stock market risk is not hedged in any way. The results of the gold-hedged index strategy, versus that of an un-hedged strategy, vary depending upon the movement of the gold futures contract and the Indian rupee. Those holding long gold futures contracts gain when the Indian rupee loses value as expressed by gold. Conversely, they lose when the opposite occurs. S&P BSE SENSEX Gold Hedged Index. The index is rebalanced monthly during the one-day roll of the gold futures contracts to equalize notional exposure to equity and gold. S&P BSE SENSEX Dynamic Gold Hedged Index. The index is rebalanced monthly during the five-day roll of the gold futures contracts to adjust the notional exposure of equity and gold. The index is also re-weighted when the equity and gold exposures exceed certain thresholds as defined in Index Maintenance. Index Family The S&P BSE SENSEX Gold Hedged Indices are part of the suite of S&P BSE indices. For information on the other S&P BSE indices, please refer to www.spdji.com and www.asiaindex.co.in. S&P Dow Jones Indices: S&P BSE SENSEX Gold Hedged Indices Methodology 2 This methodology was created by Asia Index Private Limited to achieve the aforementioned objective of measuring the underlying interest of each index governed by this methodology document. Any changes to or deviations from this methodology are made in the sole judgment and discretion of Asia Index Private Limited so that the index continues to achieve its objective. S&P Dow Jones Indices: S&P BSE SENSEX Gold Hedged Indices Methodology 3 Index Construction Approaches Each index is calculated as a combination of a long S&P BSE SENSEX position overlaid with a long position in MCX Gold Mini futures. Index Calculations Calculating the Daily Return Series. The indices are calculated based on the total return of a hypothetical portfolio consisting of long S&P BSE SENSEX and long MCX Gold Mini futures positions. The return and the total return index value are calculated as follows: = 1 푡 푆푆푆푆푆 푆푆푆푆푅 푅 푟 − = 푆1 퐺퐺퐺퐺푡 푅퐺퐺퐺퐺 = _− + _ 퐺퐺퐺퐺푟 푅ℎ=푒퐺푒푒1퐺+ 퐻푅 푆푆푆푆푅푟 ∗ 푅푆푆푆푆푆 퐻푅 퐺퐺퐺퐺푟 ∗ 푅퐺퐺퐺퐺 푡 ℎ푒퐺푒푒퐺 푟 where:퐼 � 푅 � ∗ 퐼 RSPBTR = Total return of the S&P BSE SENSEX since the previous rebalancing day RGold = Return of Gold Mini futures since the previous rebalancing day Rhedged = Return of the total return index since the previous rebalancing day It = The total return index value on day t SPBTRr = S&P BSE SENSEX total return index value on the previous rebalancing day SPBTRt = S&P BSE SENSEX total return index value on day t Goldr = Gold Mini futures closing price on the previous rebalancing day (based on the latest contract that the index rolled into) Goldt = Gold Mini futures closing price on day t HR_SPBTRr = Hedge ratio for the S&P BSE SENSEX total return index as described below HR_Goldr = Hedge ratio for the Gold Mini futures as described below Ir = The total return index value on the previous rebalancing day Asia Index Private Limited: S&P BSE SENSEX Gold Hedged Indices Methodology 4 Hedge Ratio. Index hedge ratios are as follows: For S&P BSE SENSEX Gold Hedged Index, the hedge ratio on the rebalancing day is equalized at 100%. HR_SPBTRr = 100% HR_Goldr = 100% For S&P BSE SENSEX Dynamic Gold Hedged Index, the hedge ratio is calculated as follows on reference date t which is one business day prior to the rebalancing date. _ = 푡 푡−1 푟 푆푆푆푆푅 퐼 퐻푅 푆푆푆푆푅 푡−1 ∗ 푡 _ = 푆푆푆푆푅 퐼 퐺퐺퐺퐺푡 퐼푡−1 퐻푅 퐺퐺퐺퐺푟 ∗ For more information퐺퐺퐺퐺 on푡− 1the index퐼푡 calculation methodology, please refer to S&P Dow Jones Indices’ Index Mathematics Methodology. Monthly Roll. The S&P BSE SENSEX Gold Hedged Index uses the designated Gold Mini futures on the MCX (ticker GOLDM) as illustrated in Table 1. Gold Mini futures are not held to maturity. Instead, the long futures positions roll to the next designated contract at the close of business on the fifth-to-the-last business day that is both an equity and a commodity exchange business day. The positions are rebalanced to equal weights on that day. If either the MCX or the BSE is closed on a particular day at the end of the month, that day is not used in the calculation of the five business days. Table 1: Futures Contracts Roll Rebalancing Month Roll Out Roll In Month (M) Expiration in Month (M+1) Expiration in Month (M+2) For example, at the beginning of February 2016, the hypothetical portfolio holds the Mar- 16 futures. On Febuary 23rd, the futures contract is rolled into the Apr-16 futures. The positions are rebalanced so that the notional of the Apr-16 futures equals the equity position. The equal-weight rebalancing occurs monthly.

On each day, 20% of the gold futures contract is rolled into the new contract. The roll schedule is illustrated in Table 1. Asia Index Private Limited: S&P BSE SENSEX Gold Hedged Indices Methodology 5 Index Maintenance Rebalancing S&P BSE SENSEX Gold Hedged Index. The index is rebalanced monthly so that the notional exposure to equity and gold is equal after the close of the fifth-to-the-last business day that is both an equity and a commodity exchange business day. The positions are rebalanced to equal weights on that day. If either the MCX or the BSE is closed on a particular day at the end of the month, that day is not used in the calculation of the five business days. No announcements are made. The index also has a limited loss provision as follows: • By the close of any given business day, if the S&P BSE SENSEX Gold Hedged Index loses 80% or more since the last rebalancing day then the S&P BSE SENSEX Gold Hedged Index rebalances on that business day. It rebalances again normally after the close of the fifth-to-the-last business day of the month. S&P BSE SENSEX Dynamic Gold Hedged Index. The index is rebalanced in the last five trading days of the month during the roll period of the Gold Mini futures contracts. It is also rebalanced if the difference between the values of the gold futures exposure and the equity exposure is more than 10% above or below the value of the index as of the last rebalancing, or if the sum of the equity return and gold futures return since the last rebalancing is more than 20% or below -20%. On any rebalancing day, the S&P BSE SENSEX Dynamic Gold Hedged Index calculates the number of units of futures to hold after closing, and is rebalanced on t+1.
