iPath<sup class="product">®</sup> US Treasury Long Bond Bear ETN

iPath^® US Treasury Long Bond Bear ETN (DLBS)

The iPath^® US Treasury Long Bond Bear Exchange Traded Note is linked inversely to the performance of the Barclays Capital Long Bond US Treasury Futures Targeted Exposure Index™. The index seeks to produce returns that track movements in response to an increase or decrease, as applicable, in the yields available to investors purchasing long dated U.S. Treasury bonds. The level of the index is designed to increase in response to a decrease in long dated Treasury bond yields and to decrease in response to an increase in long dated Treasury bond yields. To accomplish this objective, the performance of the index tracks the returns of a notional investment in a weighted "long" position in relation to 30-year U.S. Treasury futures contracts, as traded on the Chicago Board of Trade.

The iPath^® US Treasury Long Bond Bear ETN employs an index multiplier that provides the investor at maturity or upon redemption a participation rate of $0.10 gain or loss per each 1.00 point decrease or increase, respectively, in the level of the index. For purposes of calculating the closing indicative note value on a given day, the index multiplier is multiplied by the daily index performance, which is added to the daily interest that accrued from a notional investment of the value of the ETN at the 28-day U.S. Treasury Bill rate, from which all applicable costs and fees are deducted.

Index Returns

Index Returns measure returns over the relevant period using the change in the index level expressed as a percentage from the beginning of the relevant period to the end of the relevant period. Index Returns are for illustrative purposes only and do not represent actual iPath ETN performance. Index Returns do not reflect any management fees, transaction costs, or expenses which would reduce your actual return. Indexes are unmanaged and one cannot invest directly in an index.

Market Returns

Market Returns measure returns over the relevant period using the change in the midpoint of the bid/ask spread at 4:00 pm Eastern time (or the last midpoint of the bid/ask spread prior to 4:00 pm Eastern time) expressed as a percentage from the beginning of the relevant period to the end of the relevant period and do not represent the returns you would receive if you traded at other times. Market Returns do not account for brokerage commissions, which will reduce actual returns.

Indicative Value Returns

The Indicative Value Returns measure the returns over the relevant period using the change in the Indicative Value expressed as a percentage from the beginning of the relevant period to the end of the relevant period and reflect the current investor fee.

Redemption Value

Subject to the notification requirements described in the prospectus, Securities may be redeemed on any redemption date during the term of the Securities. If Securities are redeemed, they will receive a cash payment per Security equal to the closing indicative note value on the applicable valuation date. At least 50,000 units³ of a particular iPath ETN must be redeemed at one time in order to exercise the right to redeem Securities on any Redemption Date.

A Redemption Date is the third business day following each valuation date. Valuation Date means each business day during the term of the Securities inclusive or, if such date is not a trading day, the next succeeding trading day, not to exceed five business days.

Indicative Value

An intraday "indicative value" meant to approximate the intrinsic economic value of each iPath ETN is calculated and published by Bloomberg or a successor under the respective ticker symbols listed above. Additionally, the Daily Indicative value of each iPath ETN is calculated and posted each trading day to the Indicative Values table above. In connection with iPath ETNs, the term "indicative value" refers to the value at a given time determined based on the following equation:

Indicative Value = Closing Indicative Note Value + Intraday Index Performance Amount; provided that if such calculation results in a negative value, the intraday indicative note value will be $0;

Where:

Principal Amount per Unit = $100

Closing Indicative Note Value = The closing indicative note value of the iPath ETN on the calendar day immediately preceding the trading day on which the Indicative Value is calculated.

Intraday Index Performance Amount = (1) The Index Multiplier times (2) the difference of (a) the most recently published level of the Index on such trading day minus (b) the closing level of the Index on the index business day immediately preceding such trading day;.

Index Multiplier = The Index Multiplier as described in the pricing supplement.

The indicative value calculation is provided for reference purposes only. It is not intended as a price or quotation, or as an offer or solicitation for the purchase, sale, redemption or termination of the iPath ETNs, nor do they reflect hedging or transaction costs, credit considerations, market liquidity, or bid-offer spreads. Furthermore, as the intraday indicative note value is calculated using the closing indicative note value on the immediately preceding calendar day, the intraday indicative note value published at any time during a given trading day will not reflect the daily interest or the daily investor fee that may have accrued over the course of such trading day. Published index levels from the sponsors of the indices underlying each iPath ETN may occasionally be subject to delay or postponement. Any such delays or postponements will affect the current index level and therefore the indicative value of each iPath ETN. For this reason and others, the actual trading price of the iPath ETN may be different from their indicative value.

¹ The investor fee on the inception date of the ETNs will equal zero. On each subsequent calendar day until maturity or early redemption of the ETNs, the investor fee will equal the Yearly Fee (0.75%) times the closing indicative note value of the ETNs on the immediately preceding calendar day, divided by 365. In addition, on each "roll day" for the relevant Treasury futures contracts underlying the Index, $0.005 will be charged and deducted from the closing indicative note value of each ETN. See the applicable prospectus for more details.

² The effect of the index multiplier is to adjust the rate at which the value of the ETN changes in response to change in the underlying Index level. As a result of the index multiplier, the ETN will record a $0.10 gain or loss for every 1.00 point increase or decrease, respectively, in the level of the Index.

³ The issuer may from time to time in its sole discretion reduce, in part or in whole, the minimum redemption amount of 50,000 units, applicable to all holders, at the time the reduction becomes effective.
