Key Terms

Issuer:	Credit Suisse AG (“Credit Suisse”), acting through its Nassau Branch
Underlyings:	Each Underlying is identified in the table below, together with its Bloomberg ticker symbol, Initial Level and Knock-In Level:
	Underlying	Ticker	Initial Level	Knock-In Level
	iShares Silver Trust (“SLV”)	SLV UP
	Market Vectors Gold Miners ETF (“GDX”)	GDX UP
Interest Rate:	Expected to be between 10.50% - 12.50% per annum (approximately 5.25% - 6.25% for the term of the securities) (to be determined on the Trade Date). Interest will be calculated on a 30/360 basis.
Interest  Payment Dates:	Unless redeemed earlier, interest will be paid quarterly in arrears on June 30, 2011 and the Maturity Date, subject to the modified following business day convention. No interest will accrue or be payable following an Early Redemption.
Redemption  Amount:	At maturity, the Redemption Amount you will be entitled to receive will depend on the individual performance of each Underlying and whether a Knock-In Event occurs. If the securities are not subject to Early Redemption, the Redemption Amount will be determined as follows:
	If a Knock-In Event occurs during the Observation Period, the Redemption Amount will equal the principal amount of the securities you hold multiplied by the sum of one plus the Underlying Return of the Lowest Performing Underlying. In this case, the maximum Redemption Amount will equal the principal amount of the securities. Therefore, unless the Final Level of each of the Underlyings is greater than or equal to its Initial Level, the Redemption Amount will be less than the principal amount of the securities and you could lose your entire investment. If a Knock-In Event does not occur during the Observation Period, the Redemption Amount will equal the principal amount of the securities you hold.
	Any payment you will be entitled to receive at maturity is subject to our ability to pay our obligations as they become due.
Early Redemption:	The Issuer may redeem the securities in whole, but not in part, on any Interest Payment Date scheduled to occur on or after June 30, 2011 upon at least three business days notice at 100% of the principal amount of the securities, together with the interest payable on that Interest Payment Date.
Knock-In Event:	A Knock-In Event will occur if the closing level of either Underlying reaches or falls below the Knock-In Level for that Underlying on any trading day during the Observation Period.
Knock-In Level:	The Knock-In Level for each Underlying will be approximately 80.00% of the Initial Level of such Underlying.
Lowest Performing Underlying:	The Underlying with the lowest Underlying Return.
Underlying Return:	For each Underlying, the Underlying Return will be calculated as follows:

	Final Level – Initial Level Initial Level	; subject to a maximum of zero
Initial Level:*	For each Underlying, the closing level of such Underlying on the Trade Date.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.
Observation  Period:	The period from but excluding the Trade Date to and including the Valuation Date.
Valuation Date:†	September 27, 2011
Maturity Date:†	September 30, 2011
Listing:	The securities will not be listed on any securities exchange.
CUSIP:	22546EY40

^*In the event that the closing level of either Underlying is not available on the Trade Date, the Initial Level for such Underlying will be determined on the immediately following trading day on which a closing level is available.

^†The Valuation Date for either Underlying is subject to postponement if such date is not an underlying business day for such Underlying or as a result of a market disruption event in respect to such Underlying and the Maturity Date is subject to postponement if such date is not a business day or if the Valuation Date for either Underlying is postponed, in each case as described in the accompanying product supplement under “Description of the Securities-Market disruption events.”

Hypothetical Redemption Amounts and Total Payments on the Securities

The tables and examples below illustrate hypothetical Redemption Amounts payable at maturity and, in the case of the tables, total payments over the term of the securities (which include both payments at maturity and the total interest paid on the securities) on a $1,000 investment in the securities for a range of Underlying Returns for the Lowest Performing Underlying, both in the event a Knock-In Event does not occur and in the event a Knock-In Event does occur. The tables and examples assume that (i) the securities are not redeemed prior to maturity, (ii) the Interest Rate applicable to the securities is 11.50% per annum (approximately 5.75% for the term of the securities) (the midpoint of the expected range set forth on the cover of this pricing supplement), (iii) the term of the securities is exactly 6 months and (iv) the Knock-In Level for each Underlying is 80% of the Initial Level for such Underlying. In addition, the examples below assume that the Initial Level is $31 for SLV and $58 for GDX. The examples are intended to illustrate hypothetical calculations of only the Redemption Amount and do not illustrate the calculation or payment of any individual interest payment. The Redemption Amounts and total payment amounts set forth below are provided for illustration purposes only. The actual Redemption Amounts and total payments applicable to a purchaser of the securities will depend on several variables, including, but not limited to (a) whether the closing level of either Underlying is less than or equal to its respective Knock-In Level on any trading day during the Observation Period and (b) the Final Level of the Lowest Performing Underlying determined on the Valuation Date. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, whether and by how much the Final Level of the Lowest Performing Underlying will decrease in comparison to its Initial Level. Any payment you will be entitled to receive is subject to our ability to pay our obligations as they become due. The numbers appearing in the following tables and examples have been rounded for ease of analysis.

TABLE 1: A Knock-In Event DOES NOT occur during the Observation Period.

Percentage Change from the Initial Level to the Final Level for the Lowest Performing Underlying	Underlying Return of the Lowest Performing Underlying	Redemption Amount per $1,000 Principal Amount of Securities (Knock-In Event does not occur)	Total Interest Payment per $1,000 Principal Amount of Securities	Total Payment per $1,000 Principal Amount of Securities

TABLE 2: A Knock-In Event DOES occur during the Observation Period.

Percentage Change from the Initial Level to the Final Level for the Lowest Performing Underlying	Underlying Return of the Lowest Performing Underlying	Redemption Amount per $1,000 Principal Amount of Securities (Knock-In Event occurs)	Total Interest Payment per $1,000 Principal Amount of Securities	Total Payment per $1,000 Principal Amount of Securities

-50%	-50%	$500	$57.50	$557.50

Example 1: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during the Observation Period; and the Final Level of the Lowest Performing Underlying is less than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying       during the Observation Period	Final Level on the Valuation Date
SLV	$31	$31.00 (100% of Initial Level)	$34.10 (110% of Initial Level)
GDX	$58	$46.40 (80% of Initial Level)	$46.40 (80% of Initial Level)

Since the closing level of GDX reaches its Knock-In Level during the Observation Period, a Knock-In Event occurs. GDX is also the Lowest Performing Underlying.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of GDX — Initial Level of GDX	; subject to a maximum of 0.00
Initial Level of GDX

= ($46.40 – $58)/$58 = -0.200

Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 x (1 – 0.200) = $800

3

Example 2: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during the Observation Period; the Lowest Performing Underlying never reaches or falls below its Knock-In Level during the Observation Period; and the Final Level of the Lowest Performing Underlying is less than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying       during the Observation Period	Final Level on the Valuation Date
SLV	$31	$24.80 (80% of Initial Level)	$34.10 (110% of Initial Level)
GDX	$58	$51.04 (88% of Initial Level)	$51.04 (88% of Initial Level)

Since the closing level of SLV reaches its Knock-In Level during the Observation Period, a Knock-In Event occurs. GDX is the Lowest Performing Underlying, even though its closing level never reaches or falls below its Knock-In Level during the Observation Period.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of GDX — Initial Level of GDX	; subject to a maximum of 0.00
Initial Level of GDX

= ($51.04 – $58)/$58 = -0.120

Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 x (1 – 0.120) = $880

Example 3: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during the Observation Period; and the Final Level of the Lowest Performing Underlying is greater than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
SLV	$31	$24.80 (80% of Initial Level)	$34.10 (110% of Initial Level)
GDX	$58	$55.10 (95% of Initial Level)	$69.60 (120% of Initial Level)

Since the closing level of SLV reaches its Knock-In Level, a Knock-In Event occurs. SLV is also the Lowest Performing Underlying.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of SLV — Initial Level of SLV	; subject to a maximum of 0.00
Initial Level of SLV

= ($34.10 – $31)/ $31 = 0.100

BUT 0.100 is greater than the maximum of 0.00, so the Underlying Return of the Lowest Performing Underlying is 0.00.

Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 x (1 + 0.00) = $1,000

4

Example 4: A Knock-In Event does not occur.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
SLV	$31	$27.28 (88% of Initial Level)	$34.10 (110% of Initial Level)
GDX	$58	$52.20 (90% of Initial Level)	$63.80 (110% of Initial Level)

Since the closing level of each Underlying did not reach or fall below its Knock-In Level during the Observation Period, a Knock-In Event does not occur.

Therefore, the Redemption Amount equals $1,000.

Selected Risk Considerations

An investment in the securities involves significant risks. Investing in the securities is not equivalent to investing directly in the Underlyings. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement.

• YOU MAY RECEIVE LESS THAN THE PRINCIPAL AMOUNT AT MATURITY — You may receive less at maturity than you originally invested in the securities, or you may receive nothing, excluding any accrued or unpaid interest. If a Knock-In Event occurs during the Observation Period and the Final Level of the Lowest Performing Underlying is less than its Initial Level, you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, the Redemption Amount you will be entitled to receive will be less than the principal amount of the securities and you could lose your entire investment. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, whether and by how much the Final Level of the Lowest Performing Underlying will decrease in comparison to its Initial Level. Any payment you will be entitled to receive at maturity is subject to our ability to pay our obligations as they become due.

• THE SECURITIES WILL NOT PAY MORE THAN THE PRINCIPAL AMOUNT, PLUS ACCRUED AND UNPAID INTEREST, AT MATURITY OR UPON EARLY REDEMPTION — The securities will not pay more than the principal amount, plus accrued and unpaid interest, at maturity or upon early redemption. If the Final Level of each Underlying is greater than its respective Initial Level (regardless of whether a Knock-In Event has occurred), you will not receive the appreciation of either Underlying. Assuming the securities are held to maturity and the term of the securities is exactly 6 months, the maximum amount payable with respect to the securities is expected to be between $1,052.50 and $1,062.50 (to be determined on the Trade Date) for each $1,000 principal amount of the securities.

• THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE — Although the return on the securities will be based on the performance of the Underlyings, the payment of any amount due on the securities, including any applicable interest payments, early redemption payment or payment at maturity, is subject to the credit risk of Credit Suisse. Investors are dependent on our ability to pay all amounts due on the securities and, therefore, investors are subject to our credit risk. In addition, any decline in our credit ratings, any adverse changes in the market’s view of our creditworthiness or any increase in our credit spreads is likely to adversely affect the value of the securities prior to maturity.

• THE REDEMPTION AMOUNT PAYABLE AT MATURITY WILL BE LESS THAN THE PRINCIPAL AMOUNT OF THE SECURITIES EVEN IF A KNOCK-IN EVENT OCCURS WITH RESPECT TO ONLY ONE UNDERLYING AND THE FINAL LEVEL OF ONLY ONE UNDERLYING FALLS BELOW ITS INITIAL LEVEL — Even if the closing level of only one Underlying reaches or falls below its Knock-In Level on any trading day during the Observation Period, a Knock-In Event will have occurred. In this case, the Redemption Amount payable at maturity will be less than the principal amount of the securities if, in addition to the occurrence of a Knock-In Event, the Final Level of just one Underlying falls below its Initial Level. This will be true even if the closing level of the Lowest Performing Underlying never reached or fell below its Knock-In Level on any trading day during the Observation Period.

5

• THE SECURITIES ARE SUBJECT TO A POTENTIAL EARLY REDEMPTION, WHICH WOULD LIMIT YOUR ABILITY TO ACCRUE INTEREST OVER THE FULL TERM OF THE SECURITIES —The securities are subject to a potential early redemption. The securities may be redeemed on any Interest Payment Date scheduled to occur on or after June 30, 2011 upon at least three business days notice. If the securities are redeemed prior to the Maturity Date, you will be entitled to receive the principal amount of your securities and any accrued but unpaid interest payable on such Interest Payment Date. In this case, you will lose the opportunity to continue to accrue and be paid interest from the date of Early Redemption to the scheduled Maturity Date. If the securities are redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that yield as much interest as the securities.

• SINCE THE SECURITIES ARE LINKED TO THE PERFORMANCE OF MORE THAN ONE UNDERLYING, YOU WILL BE FULLY EXPOSED TO THE RISK OF FLUCTUATIONS IN THE LEVEL OF EACH UNDERLYING — Since the securities are linked to the performance of more than one Underlying, the securities will be linked to the individual performance of each Underlying. Because the securities are not linked to a basket, in which case the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the levels of the Underlyings to the same degree for each Underlying. For example, in the case of securities linked to a basket, the return would depend on the weighted aggregate performance of the basket components as reflected by the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component, to the extent of the weightings of such components in the basket. However, in the case of securities linked to the lowest performing of each of two Underlyings, the individual performance of each Underlying is not combined to calculate your return and the depreciation of either Underlying is not mitigated by the appreciation of the other Underlying. Instead, if a Knock-In Event occurs, the Redemption Amount payable at maturity will depend on the lowest performing of the two Underlyings to which the securities are linked.

• CERTAIN BUILT-IN COSTS ARE LIKELY TO ADVERSELY AFFECT THE VALUE OF THE SECURITIES PRIOR TO MATURITY — While the payment at maturity described in this pricing supplement is based on the full principal amount of your securities, the original issue price of the securities includes the agent’s commission and the cost of hedging our obligations under the securities through one or more of our affiliates. As a result, the price, if any, at which Credit Suisse (or its affiliates), will be willing to purchase securities from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the Maturity Date could result in a substantial loss to you. The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity.

• LACK OF LIQUIDITY — The securities will not be listed on any securities exchange. Credit Suisse (or its affiliates) intends to offer to purchase the securities in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities when you wish to do so. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which Credit Suisse (or its affiliates) is willing to buy the securities. If you have to sell your securities prior to maturity, you may not be able to do so or you may have to sell them at a substantial loss.

• POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities.

6

• MANY ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE SECURITIES —  In addition to the levels of the Underlyings on any trading day during the Observation Period, the value of the securities will be affected by a number of economic and market factors that may either offset or magnify each other, including:

  • the expected volatility of the Underlyings;

  • the time to maturity of the securities;

  • the Early Redemption feature, which is likely to limit the value of the securities;

  • interest and yield rates in the market generally;

  • global gold and silver supply and demand, which is influenced by such factors as forward selling by gold and silver producers, purchases made by gold and silver producers to unwind gold and silver hedge positions, central bank purchases and sales of gold, and production and cost levels in major gold-producing countries and in major silver-producing countries, such as Peru, Mexico and China;

  • investors’ expectations with respect to the rate of inflation;

  • geopolitical conditions and a variety of economic, financial, political, regulatory or judicial events that affect the components comprising the Underlyings, or markets generally and which may affect the levels of the Underlyings; and

  • our creditworthiness, including actual or anticipated downgrades in our credit ratings.

  Some or all of these factors may influence the price that you will receive if you choose to sell your securities prior to maturity. The impact of any of the factors set forth above may enhance or offset some or all of any change resulting from another factor or factors.

• NO OWNERSHIP RIGHTS RELATING TO THE UNDERLYINGS — Your return on the securities will not reflect the return you would realize if you actually owned the Underlyings or the equity securities that comprise the Underlyings. The return on your investment, which is based on the percentage change in the Underlyings, is not the same as the total return you would receive based on the purchase of the Underlyings or the equity securities that comprise the Underlyings.

• NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to shares of the Underlyings or the equity securities that comprise the Underlyings.

• ANTI-DILUTION PROTECTION IS LIMITED — The calculation agent will make anti-dilution adjustments for certain events affecting the shares of each Underlying. However, the calculation agent will not make an adjustment in response to all events that could affect the shares of each Underlying. If an event occurs that does not require the calculation agent to make an adjustment, the value of the securities may be materially and adversely affected. See “Description of the Securities—Adjustments—For reference funds” in the accompanying product supplement for further information.

• THERE ARE RISKS ASSOCIATED WITH THE UNDERLYINGS — Although shares of the Underlyings are listed for trading on the NYSE Arca, Inc. (“NYSE Arca”) and a number of similar securities have been traded on various national securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of the Underlyings or that there will be liquidity in the trading market. The Underlyings are subject to management risk, which is the risk that the Underlyings’ investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Pursuant to the Underylings’ investment strategy or otherwise, the investment advisor for the Underlyings may add, delete or substitute the assets held by the Underlyings. Any of these actions could adversely affect the price of the shares of each Underlying and consequently the value of the securities. For further information on the Market Vectors Gold Miners ETF, please refer to the accompanying underlying supplement, and for further information on the iShares Silver Trust, please refer to “The iShares Silver Trust” herein.

• COMMODITY PRICES ARE CHARACTERIZED BY HIGH AND UNPREDICTABLE VOLATILITY, WHICH COULD LEAD TO A HIGH AND UNPREDICTABLE VOLATILITY IN THE ISHARES SILVER TRUST – The market price of silver which comprises the iShares Silver Trust tends to be highly volatile. Commodity market prices are not related to the value of a future income or earnings stream, as tends to be the case with fixed -income and equity investments, but are subject to rapid fluctuations based on numerous factors, including changes in supply and demand relationships, governmental programs and policies, national and international monetary, trade, political and economic events, changes in interest and exchange rates, speculation and trading activities in commodities and related contracts, weather, and agricultural, trade, fiscal and exchange control policies. Many commodities are also highly cyclical. These factors may have a larger impact on commodity prices and commodity -linked instruments than on traditional fixed -income and equity securities. These variables may create additional investment risks that cause the value of the securities to be more volatile than the values of traditional securities. These and other factors may affect the price of the iShares Silver Trust, and thus the value of your securities, in unpredictable or unanticipated ways. The high volatility and cyclical nature of commodity markets may render such an investment inappropriate as the focus of an investment portfolio.

• THE VALUE OF THE ISHARES SILVER TRUST MAY NOT FULLY REPLICATE THE PERFORMANCE OF THE PRICE OF SILVER – The performance of the iShares Silver Trust may not fully replicate the performance of the price of silver due to the fees and expenses charged by the iShares Silver Trust or by restrictions on access to silver or due to other circumstances. The iShares Silver Trust does not generate any income and as the iShares Silver Trust regularly sells silver to pay for its ongoing expenses, the amount of silver represented by the iShares Silver Trust has gradually declined over time. The iShares Silver Trust sells silver to pay expenses on an ongoing basis irrespective of whether the trading price of the iShares Silver Trust rises or falls in response to changes in the price of silver. The sale of the iShares Silver Trust’s silver to pay expenses at a time of low silver prices could adversely affect the value of the iShares Silver Trust. Additionally, there is a risk that part or all of the iShares Silver Trust’s silver could be lost, damaged or stolen due to war, terrorism, theft, natural disaster or otherwise.

• THERE ARE RISKS IN SECURITIES RELATING TO COMMODITIES TRADING ON THE LONDON BULLION MARKET ASSOCIATION – The value of the iShares Silver Trust is closely related to the price of silver. Silver is traded on the London Bullion Market Association (“LBMA”). The LBMA is a self-regulated association of bullion market participants. Although all market -making members of the LBMA are supervised by the Bank of England and are required to satisfy a capital adequacy test, the LBMA itself is not a regulated entity. If the LBMA should cease operations, or if bullion trading should become subject to a value added tax or other tax or any other form of regulation currently not in place, the role of LBMA price fixings as a global benchmark for the value of silver may be adversely affected. The LBMA is a principals’ market which operates in a manner more closely analogous to over-the-counter physical commodity markets than regulated futures markets, and certain features of U.S. futures contracts are not present in the context of LBMA trading. For example, there are no daily price limits on the LBMA, which would otherwise restrict fluctuations in the prices of commodities trading on the LBMA. In a declining market, it is possible that prices would continue to decline without limitation within a trading day or over a period of trading days.

• THE PERFORMANCE OF THE MARKET VECTORS GOLD MINERS ETF MAY NOT CORRELATE TO THE PERFORMANCE OF ITS TRACKED INDEX — The Market Vectors Gold Miners ETF will generally invest in all of the equity securities included in its tracked index (the “Tracked Index”). There may, however, be instances where the Market Vectors Gold Miners ETF’s investment advisor may choose to overweight a stock in its Tracked Index, purchase securities not included in the Tracked Index that the investment advisor believes are appropriate to substitute for a security included in the Tracked Index or utilize various combinations of other available investment techniques in seeking to track accurately the Tracked Index. In addition, the performance of the

Market Vectors Gold Miners ETF will reflect additional transaction costs and fees that are not included in the calculation of the Tracked Index. Also, corporate actions with respect to the equity securities included in the Tracked Index (such as mergers and spin-offs) may impact the variance between the Market Vectors Gold Miners ETF and its Tracked Index. Finally, because the shares of the Market Vectors Gold Miners ETF are traded on a national securities exchange and are subject to market supply and investor demand, the market value of one share of the Market Vectors Gold Miners ETF may differ from the net asset value per share. For all of the foregoing reasons, the performance of the Market Vectors Gold Miners ETF may not correlate with the performance of its Tracked Index.

• RISKS ASSOCIATED WITH INVESTMENTS IN SECURITIES WITH CONCENTRATION IN A SINGLE INDUSTRY — The stocks comprising the NYSE Arca Gold Miners Index and that are generally tracked by the Market Vectors Gold Miners ETF are stocks of companies primarily engaged in the mining of gold or silver. The shares of the Market Vectors Gold Miners ETF may be subject to increased price volatility as they are linked to a single industry, market or sector and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that industry, market or sector. Because the Market Vectors Gold Miners ETF primarily invests in stocks and ADRs of companies that are involved in the gold mining industry, and to a lesser extent the silver mining industry, the shares of the Market Vectors Gold Miners ETF are subject to certain risks associated with such companies.
  
  Gold mining companies are highly dependent on the price of gold and subject to competition pressures that may have a significant effect on their financial condition. Gold prices are subject to volatile price movements over short periods of time and are affected by numerous factors. These include economic factors, including, among other things, the structure of and confidence in the global monetary system, expectations of the future rate of inflation, the relative strength of, and confidence in, the U.S. dollar (the currency in which the price of gold is generally quoted), interest rates and gold borrowing and lending rates, and global or regional economic, financial, political, regulatory, judicial or other events. Gold prices may also be affected by industry factors such as industrial and jewelry demand, lending, sales and purchases of gold by the official sector, including central banks and other governmental agencies and multilateral institutions which hold gold, levels of gold production and production costs, and short-term changes in supply and demand because of trading activities in the gold market.
  
  Silver mining companies are highly dependent on the price of silver. Silver prices can fluctuate widely and may be affected by numerous factors. These include general economic trends, technical developments, substitution issues and regulation, as well as specific factors including industrial and jewelry demand, expectations with respect to the rate of inflation, the relative strength of the U.S. dollar (the currency in which the price of silver is generally quoted) and other currencies, interest rates, central bank sales, forward sales by producers, global or regional political or economic events, and production costs and disruptions in major silver producing countries such as Peru, Mexico and China.
