1 Index specifications

The Solactive GLD^® Long USD Gold Index (“Solactive GLD^® Long USD Gold Index”, the “Index”) is an Index of Solactive AG and is calculated and distributed by Solactive AG.

The Solactive GLD^® Long USD Gold Index aims to track the daily performance of a hypothetical long position in physical gold and a short position in a basket of non-USD currencies (the “FX Basket”). The specific currencies and weights of the FX Basket are as follows: (i) Euro (57.6%), (ii) Japanese Yen (13.6%), (iii) British Pound Sterling (11.9%), (iv) Canadian Dollar (9.1%), (v) Swedish Krona (4.2%) and (vi) Swiss Franc (3.6%). Each of physical gold and each of the non-USD currencies in the FX Basket shall be an “Index Component”.

The Index will perform as follows:

The Index is calculated and published in USD every Index Business Day (barring an Index Disruption Event or Extraordinary Event).

1.4 Prices and calculation frequency

1.4.1 Index Closing Level

In calculating the Index Closing Level, the following shall be used: (i) For gold: the LBMA A.M. Gold Price; and (ii) for each of the Currency Pairs consisting of the USD and the currencies in the FX Basket, the WMCO 9am UK FX spot rate. The precise calculation is described in more detail in Section 3.

In the event that there is: (i) an incorrect calculation made in respect of the Index Closing Level; or (ii) any Gold Price or FX Price is corrected by the price source for that price, then the Index Closing Level as previously calculated shall be adjusted, on a retrospective basis, as soon as the Committee becomes aware of the occurrence of that event, as follows: (a) where (i) applies, the Committee shall undertake a correction to the calculation made in respect of the Index Closing Level for that day; and (b) where (ii) applies, the Committee shall make such adjustment as has been made by the price source for the purposes of calculating the Index Closing Level for the affected day. In each case, the Committee shall distribute such corrected or adjusted Index Closing Level through Reuters.

In the event that there is any disruption, for any reason, to the calculation or publication of those spot prices being used for the purposes of such calculation, or in the event that data is not provided to Reuters or to the pricing services of Boerse Stuttgart AG, then this may result in a disruption to the calculation of the Index Closing Level, meaning that the Index is unable to be distributed. Such disruption shall only continue for so long as the underlying price source continues to be unavailable for the purposes of calculation of the Index Level or any of the components of the Index.

1.5 Index Disruption Events

It shall be an Index Disruption Event if either an FX Basket Disruption Event or Gold Disruption Event occurs or exists; provided that, where an Extraordinary Event has occurred or exists, such Extraordinary Event shall take precedence.

“FX Basket Disruption Event” means the occurrence and existence of any of the following on any Index Business Day with respect to the FX Basket Currencies forming part of the FX Basket:

“Gold Disruption Event” means the occurrence and existence of any of the following on any Index Business Day with respect to Gold:

4

1.5a Extraordinary Events

It shall be an Extraordinary Event if an Index Disruption Event continues for 10 Index Business Days. In the case of an Extraordinary Event, the Committee shall be responsible for selecting that price or component which is to be used in place of that price or component which is or has become unavailable (so changing the composition of the Index to substitute that price or component which has become unavailable).

1.6 Decision-making Bodies for Index Disruption Events and Extraordinary Events

A Committee composed of staff from Solactive AG is responsible for decisions regarding the composition of Solactive GLD^® Long USD Gold Index from time to time, as well as any amendments that are required to be made to these Guidelines or to the rules for calculation of the Index (in this document referred to as the “Committee” or the “Index Committee”). Notwithstanding the foregoing, Solactive AG may only change these Guidelines to maintain compliance with the relevant laws and regulations applicable with the regard to an index provider or index administrator, and to ensure the continued integrity of the index. No Committee member has an active role in the markets in which the Index Components are traded (such as the LBMA for Gold). In making a determination regarding the existence of any Index Disruption Event or an Extraordinary Event, the Committee may consult with participants in the markets in which the Index Components are traded. In any event, the Index Committee shall remain independent of these market participants and shall at all times be solely responsible for the determination of the existence of any Index Disruption Event or an Extraordinary Event.

1.6.1 Decisions with Respect to an Index Disruption Event.

If the Index Sponsor determines in good faith that an Index Disruption Event has occurred and exists (and no Extraordinary Event has occurred and exists) with respect to the Reference Price of any Index component on any Index Business Day, the Index Sponsor will calculate the Index as follows –

1.6.2 Decisions with Respect to an Extraordinary Event.

The Committee shall also make any decisions regarding the future composition of the Solactive GLD^® Long USD Gold Index, in the event that any Extraordinary Events should occur, and shall thereafter implement any necessary adjustments to the Index that might be required.

Provided that all of the relevant information is readily available to Solactive AG, Solactive AG shall use its reasonable endeavours to provide at least two Index Business Days prior notice before the day on which the relevant change to the Index composition will become effective.

1.7 Publication

All specifications and information relevant for calculating the Index are made available on the http://www.solactive.de web page and sub-pages.

2 Composition of the Index

2.1 Currency Pairs, Target Weights, and Rebalancing

At the close of each Index Business Day, the weight of each Currency Pair in the FX Basket shall be reset to the target weight for that currency, as is set out below:

The currency weights used in the Index are identical to those determined by the U.S. Federal Reserve in 1978¹ and used in the “index of the weighted-average foreign exchange value of the U.S. Dollar”. The weights were fixed and reflected the weighted average of the exchange values of the U.S. Dollar against 10 major foreign currencies. The weight of each currency in the index was equal to the country’s average share of total trade (imports plus exports) for the five years 1972 to 1976. The base period of the index is March 1973, which corresponds to the start of the period of generalized floating of exchange rate.

The U.S. Federal Reserve revised the weights in October 1998², when the Euro was about to replace 5 of the currencies initially included in the index (German deutsche mark, French franc, Italian lira, Dutch guilder and Belgium franc). The weights attributed to the Euro are equal to the aggregated weights of the 5 currencies it substituted.

Since then, the U.S. Federal Reserve has not made other changes to the currency weights.

3 Calculation of the Index

3.1 Determination of the Index Closing Level

(a) Index Closing Level when no Index Disruption Event has occurred on the current or previous Index Business Day and exists on the current Index Business Day

The level of the Index Closing Level shall be calculated in accordance with the following formula:

		= LBMA A.M. Gold Price on Index Business Day t
		= The Index Closing Level in terms of a number of ounces of gold on Index Business Day t, calculated as
		Where:
						= Number of currencies currency pairs included in the FX Basket
						= FX profit and loss for currency i on Index Business Day t, calculated as
		If currency i is EUR/USD or GBP/USD, then
		Otherwise
				Where:
						= Target Weight of currency i on Index Business Day t, as defined in Section 2.1.
						= LBMA P.M. Gold Price on Index Business Day t. However, on days where the LBMA does not plan to publish an LBMA P.M. Gold Price (for instance on the Index Business Day before 25th December or 31st December), it should be the LBMA P.M. Gold Price on the Index Business Day immediately preceding Index Business Day t.
						= WMCo 4pm UK FX spot rate for currency i on Index Business Day t
						= FX return of currency i on Index Business Day t, calculated as
						If currency i is EUR/USD or GBP/USD, then
						Otherwise

8

						Where:
								= WMCo 9am UK FX spot rate for currency i on Index Business Day t
								=WMCo 9am UK FX 1 week forward fixing for currency i on Index Business Day t
								=FX spot settlement date for currency i entered on Index Business Day t as determined by market conventions
								= FX 1 week forward settlement date for currency i entered on Index Business Day t as determined by market conventions

(b) Index Closing Level when an FX Index Disruption Event with respect to the WMCO 9am UK FX Spot Rate has occurred and exists

On any day that an FX Index Disruption Event has occurred and exists with respect to an affected currency, the return for the affected currency on Index Business Day t shall be equal to zero but the return for the non-affected currencies will be calculated in the ordinary course.

(c) Index Closing Level when a Gold Index Disruption Event with respect to the LBMA AM Gold Price has occurred and exists

On any Index Business Day that a Gold Index Disruption Event has occurred and exists, then the Index Closing Level on that Index Business Day shall be equal to Index Closing Level from the prior Index Business Day.

(d) Index Closing Level after Index Disruption Event no longer exists

If currency i is EUR/USD or GBP/USD, then

Otherwise

is the Index Business Day before the first Index Business Day of one of the following Index Disruption Events - (i) an FX Basket Disruption Event with respect to the WMCO 9am UK FX Spot Rate or (ii) a Gold Disruption Event with respect to the LBMA AM Gold Price.
