3.  Related Party Transactions

The Partnership’s cash is on deposit in commodity brokerage accounts with Morgan Stanley.  Monthly, MS&Co. pays the Partnership interest income on 100% of the average daily equity maintained in cash in the Partnership’s account during each month at a rate equal to 80% of the monthly average of the 4-week

MORGAN STANLEY SMITH BARNEY SPECTRUM STRATEGIC L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

U.S. Treasury bill discount rate.  MS&Co. will retain any interest earned in excess of the interest paid by MS&Co. to the Partnership.  For purposes of such interest payments, net assets do not include monies due to the Partnership on Futures Interests that have not been received.  The Partnership pays brokerage fees to MS&Co.

4.  Financial Instruments

The Partnership trades Futures Interests.  Subsequent to December 1, 2011, the Partnership trades futures and forwards through its investment in the Funds.  Futures and forwards represent contracts for delayed delivery of an instrument at a specified date and price.  Futures Interests are open commitments until settlement date, at which time they are realized.  They are valued at fair value, generally on a daily basis, and the unrealized gains and losses on open contracts (the difference between contract trade price and market price) are reported in the Partnership’s Statements of Financial Condition as a net unrealized gain or loss on open contracts.  The resulting net change in unrealized gains and losses is reflected in the “Net change in unrealized depreciation on investment in BHM I, LLC”, “Net change in unrealized appreciation (depreciation) on investment in PGR Master Fund” and “Net change in unrealized appreciation (depreciation) on investment in MB Master Fund” on open contracts from one period to the next on the Statements of Income and Expenses.  The fair value of exchange-traded futures, options and forward contracts is determined by the various futures exchanges, and reflects the settlement price for each contract as of the close of business on the last business day of the reporting period.

- 10 -

MORGAN STANLEY SMITH BARNEY SPECTRUM STRATEGIC L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The fair value of foreign currency forward contracts is extrapolated on a forward basis from the spot prices quoted as of approximately 3:00 P.M. (E.T.) of the last business day of the reporting period from various exchanges.  The fair value of non-exchange-traded foreign currency option contracts is calculated by applying an industry standard model application for options valuation of foreign currency options, using as input the spot prices, interest rates, and option implied volatilities quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period.  Risk arises from changes in the value of these contracts and the potential inability of counterparties to perform under the terms of the contracts.  There are numerous factors which may significantly influence the fair value of these contracts, including interest rate volatility.

The Partnership may invest in affiliated underlying funds.  Relevant authoritative guidance permits, as a practical expedient, the Partnership to measure the fair value of its investment in affiliated underlying funds on the basis of the net asset value per share of such investments (or the equivalent) if the net asset value per share of such investments (or the equivalent) is calculated in a manner consistent with the measurement principles of applicable authoritative guidance as of the Partnership’s reporting date.  The fair value of each affiliated underlying fund is based on the information provided by the affiliated underlying fund which reflects the Partnership’s share of the fair value of the net assets of the affiliated underlying fund (i.e., the practical expedient is used).

- 11 -

MORGAN STANLEY SMITH BARNEY SPECTRUM STRATEGIC L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The fair value of exchange-traded contracts is based on the settlement price quoted by the exchange on the day with respect to which fair value is being determined.  If an exchange-traded contract could not have

been liquidated on such day due to the operation of daily limits or other rules of the exchange, the settlement price will be equal to the settlement price on the first subsequent day on which the contract could be liquidated.   The fair value of off-exchange-traded contracts is based on the fair value quoted by the counterparty.

The Partnership’s contracts are accounted for on a trade-date basis.  The Partnership accounts for its derivative investments as described in Note 5. Derivatives and Hedging as required by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”).A derivative is defined as a financial instrument or other contract that has all three of the following characteristics:

1)   a) One or more “underlyings” and b) one or more “notional amounts” or payment provisions or both;

2)   Requires no initial net investment or a smaller initial net investment than would be required for other types of contracts that would be expected to have a similar response relative to changes in market factors; and

3)   Terms that require or permit net settlement.

Generally, derivatives include futures, forward, swaps or options contracts, and other financial instruments with similar characteristics such as caps, floors, and collars.

- 12 -

MORGAN STANLEY SMITH BARNEY SPECTRUM STRATEGIC L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The futures, forwards and options traded by the Partnership involve varying degrees of related market risk.  Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership’s open positions, and consequently in its earnings, whether realized or unrealized, and cash flow.  Gains and losses on open positions of exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are settled daily through variation margin.  Gains and losses on off-exchange-traded forward currency contracts are settled on termination of the contract.  Gains and losses on off-exchange-traded forward currency options contracts are settled upon an agreed-upon settlement date.

5.  Derivatives and Hedging

As of June 30, 2013 and December 31, 2012, the Partnership held no futures and forward contracts; therefore, there were no net unrealized gains or losses on futures or forward contracts.

The following tables summarize the net trading results of the Partnership for the three and six months  ended June 30, 2013 and 2012, respectively.

6.  Fair Value Measurements and Disclosures

On October 1, 2012, the FASB issued Accounting Standards Update (“ASU”) 2012-04 “Technical Corrections and Improvements”, which makes minor technical corrections and clarifications to ASC 820, “Fair Value Measurements and Disclosures”. When the FASB issued Statement 157 (codified in ASC 820), it conformed the use of the term “fair value” in certain pre-Codification standards but not others. ASU 2012-04 conforms the term’s use throughout the ASC “to fully reflect the fair value measurement and disclosure requirements” of ASC 820. The ASU also amends the requirements that must be met for an investment company to qualify for the exemption from presenting a statement of cash flows.  Specifically, it eliminates the requirements that substantially all of an entity’s investments

- 15 -

MORGAN STANLEY SMITH BARNEY SPECTRUM STRATEGIC L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

be carried at “market value” and that the investments be highly liquid. Instead, it requires substantially all of the entity’s investments to be carried at “fair value” and classified as Level 1 or Level 2 measurements under ASC 820. The amendments are effective for fiscal periods beginning after December 15, 2012. The adoption of this ASU did not have a significant impact on the Partnership’s financial statements.

Financial instruments are carried at fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  Assets and liabilities carried at fair value are classified and disclosed in the following three levels: Level 1 - unadjusted quoted market prices in active markets for identical assets and liabilities; Level 2 - inputs other than unadjusted quoted market prices that are observable for the asset or liability, either directly or indirectly (including unadjusted quoted market prices for similar investments, interest rates and credit risk); and Level 3 - unobservable inputs for the asset or liability (including the Partnership’s own assumptions used in determining the fair value of investments).  In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy.  In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.  The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment.

7.  Other Pronouncements

In June 2013, the FASB issued ASU 2013-08, “Financial Services – Investments Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements”.  ASU 2013-08 changes the approach to the investment company assessment, requires non-controlling ownership interests in other investment companies to be measured at fair value, and requires additional disclosures about the investment company’s status as an investment company.  The amendments are effective for interim and annual reporting periods beginning after December 15, 2013.  The Partnership is currently evaluating the impact this pronouncement would have on the financial statements.

8.  Income Taxes

No provision for income taxes has been made in the accompanying financial statements, as partners are individually responsible for reporting income or loss based upon their respective share of the Partnership’s revenues and expenses for income tax purposes. The Partnership files U.S. federal and state tax returns.

The guidance issued by the FASB on income taxes clarifies the accounting for uncertainty in income taxes recognized in the Partnership's financial statements, and prescribes a recognition threshold and

NOTES TO FINANCIAL STATEMENTS (CONCLUDED)

expected to be taken.  The Partnership has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements as of June 30, 2013 and December 31, 2012.  If applicable, the Partnership recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in other expenses in the Statements of Income and Expenses.  Generally, the 2009 through 2012 tax years remain subject to examination by U.S. federal and most state tax authorities.  No income tax returns are currently under examination.

9.  Subsequent Events

Management of Ceres performed its evaluation of subsequent events through the date of filing, and has determined that there were no subsequent events requiring adjustments of or disclosure in the financial statements.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

As of June 30, 2013, the percentage of assets allocated to each market sector was approximately as follows: Interest Rate 4.54%; Currency 2.63%; Equity 5.36%; and Commodity 87.47%.

Liquidity.  The Partnership deposits its assets with MS&Co. as its clearing commodity broker in separate futures, forward and options trading accounts established for each Trading Advisor.  Such assets are used as margin to engage in trading and may be used as margin solely for the Partnership’s trading. The assets are held in either non-interest bearing bank accounts or in securities and instruments permitted by the CFTC for investment of customer segregated or secured funds.  Since the Partnership’s sole purpose is to trade in futures, forwards and options, it is expected that the Partnership will continue to own such liquid assets for margin purposes.

The Partnership’s investment in futures, forwards and options may, from time to time, be illiquid.  Most U.S. futures exchanges limit fluctuations in prices during a single day by regulations referred to as “daily price fluctuation limits” or “daily limits.”  Trades may not be executed at prices beyond the daily limit.  If the price for a particular futures or options contract has increased or decreased by an amount equal to the daily limit, positions in that futures or options contract can neither be taken nor liquidated unless traders are willing to effect trades at or within the limit. Futures prices have occasionally moved the daily limit for several consecutive days with little or no trading.  These market conditions could prevent the Partnership from promptly liquidating its futures or options contracts and result in restrictions on redemptions.

- 21 -

There is no limitation on daily price moves in trading forward contracts on foreign currencies.  The markets for some world currencies have low trading volume and are illiquid, which may prevent the Partnership from trading in potentially profitable markets or prevent the Partnership from promptly liquidating unfavorable positions in such markets, subjecting it to substantial losses.  Either of these market conditions could result in restrictions on redemptions.  For the periods covered by this report, illiquidity has not materially affected the Partnership’s assets.

There are no known material trends, demands, commitments, events, or uncertainties at the present time that are reasonably likely to result in the Partnership’s liquidity increasing or decreasing in any material way.

As of June 30, 2013, approximately 0% of the Partnership’s total investment exposure through investments in underlying funds is forward contracts which are off-exchange traded.

Capital Resources.  The Partnership does not have, nor does it expect to have, any capital assets.  Redemptions of units of limited partnership interest (“Unit(s)”) in the future will affect the amount of funds available for investments in futures, forwards and options in subsequent periods.  It is not possible to estimate the amount, and therefore the impact, of future outflows of Units.

There are no known material trends, favorable or unfavorable, that would affect, nor any expected material changes to, the Partnership’s capital resource arrangements at the present time.

- 22 -

Off-Balance Sheet Arrangements and Contractual Obligations.  The Partnership does not have any off-balance sheet arrangements, nor does it have contractual obligations or commercial commitments to make future payments that would affect its liquidity or capital resources.

Results of Operations

General.  The Partnership’s results depend on the Trading Advisors and the ability of each Trading Advisor’s trading program to take advantage of price movements in the futures, forward and options markets.  Blenheim trades its Global Markets Strategy—Futures/FX on behalf of the Partnership.  The objective of the Global Markets Strategy is to capture substantial profits through the establishment of risk-controlled, strategic investment positions in markets where Blenheim has identified an unsustainable level of market disequilibrium that has not been reflected in the current market price. The essence of Blenheim’s trading approach is its ability to use discretion in formulating the most effective mix of trading methodologies, investment vehicles, and markets to maintain performance objectives. As trading opportunities are identified, Blenheim analyzes potential trading applications in order to achieve maximum capital appreciation with prudent risk management procedures.

Aventis trades its Aventis Barbarian Program on behalf of the Partnership.  The Aventis Barbarian Program is based on an ensemble of three discretionary subprograms: spreads, flat price directional, and options trading.  This type of trading is based primarily on the fundamentals of the market (i.e., changes in supply or demand of a commodity).  It will also include supply and demand of the pit, (i.e., discovery of over bought and over sold conditions).

- 23 -

PGR trades its PGR Mayfair Program on behalf of the Partnership.  PGR’s futures investment program seeks to profit over the medium term by exploiting inefficiencies in futures and forward markets across a broad range of asset classes and geographic regions. Proprietary models developed by the founding partners are implemented in an in-house trading system which systematically processes real-time data and executes trades automatically on electronic future exchanges and foreign exchange trading platforms.

The following chart sets forth the percentage and the amount of the Partnership’s net assets allocated to each Trading Advisor for the periods ending June 30, 2013, and March 31, 2013, respectively, and the change during the applicable period.

Trading Advisor	Allocations as of  June 30,        2013 (%)	Allocations as    of March 31,   2013 (%)	Allocations as of June 30,       2013($)	Allocations as      of March 31,     2013 ($)	Change during  the period (%)
Blenheim	84.77	82.47	51,946,384	56,939,603	(8.77)%
Aventis	8.99	9.73	5,507,269	6,717,195	(18.01)%
PGR	6.24	7.80	3,825,238	5,383,975	(28.95)%

The following presents a summary of the Partnership’s operations for the three and six months ended June 30, 2013 and 2012, and a general discussion of its trading activities during each period.  It is important to note, however, that the Trading Advisors trade in various markets at different times and that prior activity in a particular market does not mean that such market will be actively traded by the Trading Advisors or will be profitable in the future.  Consequently, the results of operations of the Partnership are difficult to discuss other than in the context of the Trading Advisors’ trading activities on behalf of the Partnership during the period in question.  Past performance is no guarantee of future results.

- 24 -

The Partnership’s results of operations set forth in the financial statements on pages 2 through 20 of this report are prepared in accordance with U.S. GAAP, which require the use of certain accounting policies that affect the amounts reported in these financial statements, including the following: the contracts the Partnership trades are accounted for on a trade-date basis and marked to market on a daily basis.  The difference between their original contract value and fair value is recorded on the Statements of Income and Expenses as “Net change in unrealized appreciation on investments in BHM I, LLC”, “Net change in unrealized appreciation (depreciation) on investment in PGR Master Fund” and “Net change in unrealized appreciation on investment in MB Master Fund” for open contracts and recorded as “Net realized trading gain (loss) on investment in BHM I, LLC, PGR Master Fund and MB Master Fund” when open positions are closed out.  The sum of these amounts constitutes the Partnership’s trading results.  The market value of a futures contract is the settlement price on the exchange on which that futures contract is traded on a particular day.  The value of a foreign currency forward contract is based on the spot rate as of approximately 3:00 P.M. (E.T.) the close of the business day. Interest income, as well as management fees, incentive fees, and brokerage fees of the Partnership are recorded on an accrual basis.

Ceres believes that, based on the nature of the operations of the Partnership, no assumptions relating to the application of critical accounting policies other than those presently used could reasonably affect reported amounts.

For the Three and Six Months Ended June 30, 2013

The Partnership recorded total trading results including interest income totaling $(1,855,167) and expenses totaling $1,448,998, resulting in a net loss of $3,304,165 for the three months ended June 30, 2013.

The Partnership’s net asset value per Unit decreased from $14.24 at March 31, 2013, to $13.53 at June 30, 2013.

- 25 -

During the second quarter, the Partnership posted a loss in Net Asset Value as trading losses in metals, currencies, and global stock indices offset gains from trading agriculturals and global interest rates. Trading results in the energy sector were relatively flat and had no material impact on the Partnership’s performance for the quarter. The most significant losses were incurred within the metals markets during April and June, from long positions in palladium and platinum futures as prices declined after U.S. economic data topped estimates, eroding the appeal of the metals as a store of value.  Furthermore, prices of palladium and platinum futures continued to decline as a South African mining union said it would postpone a potential strike until after talks with government leaders. Within the currency sector, losses were incurred primarily during June from short positions in the Japanese yen versus the U.S. dollar as the value of the yen rose on speculation the Bank of Japan may limit its monetary stimulus program to a two-year period. Meanwhile, long positions in the Swiss franc, euro, and British pound recorded losses as the value of these European currencies moved lower relative to the U.S. dollar during the latter half of the month on concern of weakness in European economies. Within the global stock index sector, losses were incurred primarily during June from long positions in Pacific Rim and European equity index futures as prices declined on concern central banks may scale back economic stimulus measures. A portion of the Partnership’s losses during the quarter was offset by gains experienced within the agricultural sector, primarily during June, from short positions in corn and soybean futures as prices fell during the first half of the month after warm weather and soil moisture boosted the outlook for U.S. yields.  Additional gains were recorded in this sector during April from long cocoa futures positions. Within the global interest rate sector, gains were experienced during June from short positions in U.S. fixed income futures as prices moved lower on speculation the U.S. Federal Reserve may curtail its asset purchase program.

- 26 -

The Partnership recorded total trading results including interest income totaling $220,911 and expenses totaling $3,040,039, resulting in a net loss of $3,260,950 for the six months ended June 30, 2013.  The Partnership’s net asset value per Unit decreased from $14.25 at December 31, 2012, to $13.53 at June 30, 2013.

During the first six months of the year, the Partnership posted a loss in Net Asset Value as losses from trading in global interest rates, currencies, and metals more than offset gains from trading global stock indices, agriculturals, and energies.  The most significant losses were incurred within the global interest rate sector, primarily during February, from short futures positions in U.S. government bonds and notes as prices rose after U.S. Federal Reserve Chairman, Ben Bernanke, announced that trailing inflation allowed the central bank to continue its bond buying program. Additional losses from short futures positions in U.S. government bonds and notes were experienced during March as prices advanced in the latter half of the month on concerns economic uncertainty in Cypress would deepen Europe’s debt crisis. Within the currency sector, losses were incurred primarily during June from short positions in the Japanese yen versus the U.S. dollar as the value of the yen rose on speculation the Bank of Japan may limit its monetary stimulus program to a two-year period. Meanwhile, long positions in the Swiss franc, euro, and British pound also recorded losses during June as the value of these European currencies moved lower relative to the U.S. dollar during the latter half of the month on concern of weakness in European economies. Losses were also incurred in the metals sector during April from short positions in gold and silver futures as precious metals prices fell sharply at mid-month on fears Cyprus and other crisis-hit countries may be forced to sell their gold reserves.  Additional losses were incurred during June from long positions in palladium and platinum futures as prices declined after U.S. economic data topped

- 27 -

estimates, eroding the appeal of the metals as a store of value. The Partnership’s losses during the first half of the year were partially offset by gains experienced within the global stock index sector, primarily during April, from long positions in U.S. and Pacific Rim equity index futures as prices rose amid optimism central banks will maintain loose monetary policies to boost economic growth. Within the agricultural sector, gains were experienced primarily during June from short positions in corn and soybean futures as prices fell during the first half of the month after warm weather and soil moisture boosted the outlook for U.S. yields. Gains were also achieved within the energy sector, primarily during February, from short positions in crude oil futures as prices declined on reports that the U.S. economy grew less-than-expected in January and amid reports of increased U.S. crude stockpiles.

For the Three and Six Months Ended June 30, 2012

The Partnership recorded total trading results including interest income totaling $(7,108,453) and expenses totaling $2,242,753, resulting in a net loss of $9,351,206 for the three months ended June 30, 2012.

The Partnership’s net asset value per Unit decreased from $16.16 at March 31, 2012, to $14.73 at June 30, 2012.

The most significant trading losses were incurred within the metals markets during May and June, from long futures positions in palladium as prices fell on concerns that Europe’s worsening debt crisis and a slowing U.S. recovery signal weaker demand for metals. Within the agricultural sector, losses were incurred primarily during May from long positions in corn futures as prices moved lower on speculation that rain will improve prospects for newly planted crops in the U.S. Additional losses were experienced from long positions in soybean futures as prices declined as rain and cool weather in some U.S. growing

areas boosted prospects for recently planted soybean crops. Within the global interest rate markets, losses were incurred primarily during April from short positions in U.S. fixed-income futures as prices advanced as Standard & Poor’s cut Spain’s credit rating, adding to concerns that central banks and politicians are failing to contain the European debt crisis. Within the global stock index sector, losses were incurred primarily during May from long positions in U.S. and Pacific Rim equity index futures as prices declined amid an unexpected rise in the U.S. unemployment rate and weakening economic data from China and Europe. Within the currency sector, losses were incurred during April and June. During April, losses were incurred from long positions in the Brazilian real versus the U.S. dollar as the value of the Brazilian real fell relative to the U.S. dollar after the Brazilian Central Bank purchased U.S. dollars in order to protect exporters from a strong local currency. During June, losses were incurred from short positions in the euro as the value of the euro rose against the U.S. dollar after European Union leaders eased terms on Spanish bank loans and moved towards resolving the region’s debt crisis. Within the energy sector, smaller losses were incurred primarily during May and June. During May, losses were incurred from long futures positions in crude oil and its related products as prices declined after crude stockpiles increased in the U.S. During June, losses were incurred from short positions in natural gas futures as prices advanced to the highest level since January on forecasts of above-normal temperatures across the U.S. Prices continued to rise after a U.S. government report revealed a smaller-than-expected gain in inventories.

The Partnership recorded total trading results including interest income totaling $(3,356,569) and expenses totaling $4,794,816, resulting in a net loss of $8,151,385 for the six months ended June 30, 2012.  The Partnership’s net asset value per Unit decreased from $16.02 at December 31, 2011, to $14.73 at June 30, 2012.

- 29 -

The most significant trading losses were incurred within the metals markets, primarily during March and May. During March, losses were incurred from long positions in palladium and aluminum futures as prices dropped on speculation of reduced demand from China, the world’s biggest metals purchaser. During May, losses were incurred from long futures positions in palladium as prices fell on concern that Europe’s worsening debt crisis and a slowing U.S. recovery signal weaker demand for metals. Within the global interest rate markets, losses were incurred primarily during April from short positions in U.S. fixed-income futures as prices advanced as Standard & Poor’s cut Spain’s credit rating, adding to concern central banks and politicians are failing to contain the European debt crisis. Within the currency markets, losses were incurred primarily during March and June. During March, losses were incurred from long positions in the Brazilian real versus the U.S. dollar as concern over earnings in China reduced demand for higher-yielding currency assets. During June, losses were incurred from short positions in the euro as the value of the euro rose against the U.S. dollar after European Union leaders eased terms on Spanish bank loans and moved towards resolving the region’s debt crisis. Within the agricultural markets, losses were incurred primarily during May and June from long positions in corn futures as prices moved lower on speculation that rain will improve prospects for newly planted crops in the U.S. Additional losses were experienced from long positions in soybean futures as prices declined as rain and cool weather in some U.S. growing areas boosted prospects for recently planted soybean crops. Within the global stock index markets, losses were incurred primarily during May from long positions in U.S. and Pacific Rim equity index futures as prices declined amid an unexpected rise in the U.S. unemployment rate and weakening economic data from China and Europe. A portion of the Partnership’s losses for the first half of the year was offset by gains achieved within the energy sector, primarily during February, from long futures positions in crude oil and its related products as prices increased after Iran

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Introduction

The Partnership is a commodity pool engaged primarily in the speculative trading of futures, forwards and options.  The market-sensitive instruments held by the Partnership are acquired for speculative trading purposes only and, as a result, all or substantially all of the Partnership’s assets are at risk of trading loss.  Unlike an operating company, the risk of market-sensitive instruments is inherent to the primary business activity of the Partnership.

The futures, forwards and options on such contracts traded by the Partnership involve varying degrees of related market risk.  Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership’s open positions, and consequently in its earnings, whether realized or unrealized, and cash flow.  Gains and losses on open positions of exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are settled daily through variation margin.  Gains and losses on off-exchange-traded forward currency contracts and forward currency options contracts are settled upon termination of the contract.  Gains and losses on off-exchange-traded forward currency options contracts are settled upon an agreed upon settlement date.

- 31 -

The Partnership’s total market risk may increase or decrease as it is influenced by a wide variety of factors, including, but not limited to, the diversification among the Partnership’s open positions, the volatility present within the markets, and the liquidity of the markets.

The face value of the market sector instruments held by the Partnership is typically many times the applicable margin requirements.  Margin requirements generally range between 2% and 15% of contract face value.  Additionally, the use of leverage causes the face value of the market sector instruments held by the Partnership typically to be many times the total capitalization of the Partnership.

The Partnership’s past performance is no guarantee of its future results.  Any attempt to numerically quantify the Partnership’s market risk is limited by the uncertainty of its speculative trading.  The Partnership’s speculative trading and use of leverage may cause future losses and volatility (i.e., “risk of ruin”) that far exceed the Partnership’s experience to date as discussed under the “Partnership’s Value at Risk in Different Market Sectors” section and significantly exceed the Value at Risk (“VaR”) tables disclosed.

Limited partners will not be liable for losses exceeding the current net asset value of their investment.

Quantifying the Partnership’s Trading Value at Risk

The following quantitative disclosures regarding the Partnership’s market risk exposures contain “forward-looking statements” within the meaning of the safe harbor from civil liability provided for such statements by the Private Securities Litigation Reform Act of 1995 (set forth in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934).  All quantitative disclosures in this section

- 32 -

are deemed to be forward-looking statements for purposes of the safe harbor, except for statements of historical fact.

The Partnership accounts for open positions on the basis of fair value accounting principles.  Any loss in the market value of the Partnership’s open positions is directly reflected in the Partnership’s earnings and cash flow.

The Partnership’s risk exposure in the market sectors traded by the Trading Advisors is estimated below in terms of VaR.  Please note that the VaR model is used to numerically quantify market risk for historic reporting purposes only and is not utilized by either Ceres or the Trading Advisors in their daily risk management activities.

VaR is a measure of the maximum amount which the Partnership could reasonably be expected to lose in a given market sector.  However, the inherent uncertainty of the Partnership’s speculative trading and the recurrence in the markets traded by the Partnership of market movements far exceeding expectations could result in actual trading or non-trading losses far beyond the indicated VaR of the Partnership’s experience to date (i.e., “risk of ruin”).  In light of the foregoing as well as the risks and uncertainties intrinsic to all future projections, the inclusion of the quantification in this section should not be considered to constitute any assurance or representation that the Partnership’s losses in any market sector will be limited to VaR or by the Partnership’s attempts to manage its market risk.

- 33 -

Exchange maintenance margin requirements have been used by the Partnership as the measure of its VaR.  Maintenance margin requirements are set by exchanges to equal or exceed the maximum losses reasonably expected to be incurred in the fair value of any given contract in 95% - 99% of any one-day interval.  Maintenance margin has been used rather than the more generally available initial margin, because initial margin includes a credit risk component, which is not relevant to VaR.

The Partnership’s Value at Risk in Different Market Sectors

The following tables indicate the trading VaR associated with the Partnership’s open positions by market category as of June 30, 2013 and December 31, 2012, and the highest, lowest and average values during the three months ended June 30, 2013 and for the twelve months ended December 31, 2012.  All open position trading risk exposures of the Partnership have been included in calculating the figures set forth below.  There has been no material change in the trading VaR information previously disclosed in the Form 10-K.

As of June 30, 2013, the Partnership’s total capitalization was approximately $61 million.

Limitations on Value at Risk as an Assessment of Market Risk

VaR models permit estimation of a portfolio’s aggregate market risk exposure, incorporating a range of varied market risks, reflect risk reduction due to portfolio diversification or hedging activities, and can cover a wide range of portfolio assets. However, VaR risk measures should be viewed in light of the methodology’s limitations, which include, but may not be limited to the following:

·   past changes in market risk factors will not always result in accurate predictions of the distributions and correlations of future market movements;

·   changes in portfolio value caused by market movements may differ from those of the VaR model;

·   VaR results reflect past market fluctuations applied to current trading positions while future risk depends on future positions;

·   VaR using a one-day time horizon does not fully capture the market risk of positions that cannot be liquidated or hedged within one day; and

·   the historical market risk factor data used for VaR estimation may provide only limited insight into losses that could be incurred under certain unusual market movements.

Non-Trading Risk

The Partnership has non-trading market risk on its foreign cash balances not needed for margin.  These balances and any market risk they may represent are immaterial.

Materiality, as used throughout this section, is based on an assessment of reasonably possible market movements and any associated potential losses, taking into account the leverage, optionality, and multiplier features of the Partnership’s market-sensitive instruments, in relation to the Partnership’s net assets.

Qualitative Disclosures Regarding Primary Trading Risk Exposures

The following qualitative disclosures regarding the Partnership’s market risk exposures - except for (A) those disclosures that are statements of historical fact and (B) the descriptions of how the Partnership manages its primary market risk exposures - constitute forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. The Partnership’s primary market risk exposures, as well as the strategies used and to be used by Ceres and the Trading Advisors for managing such exposures, are subject to numerous uncertainties, contingencies and risks, any one of which could cause the actual results of the Partnership’s risk controls to differ materially from the objectives of such strategies.  Government interventions, defaults and expropriations, illiquid markets, the emergence of dominant fundamental factors, political upheavals, changes in historical price relationships, an influx of new market participants, increased regulation, and many other factors could result in material losses, as well as in material changes to the risk exposures and the risk management strategies of the Partnership.  Investors must be prepared to lose all or substantially all of their investment in the Partnership.

Qualitative Disclosures Regarding Means of Managing Risk Exposure

The Partnership and the Trading Advisors, separately, attempt to manage the risk of the Partnership’s open positions in essentially the same manner in all market categories traded. Ceres attempts to manage market exposure by diversifying the Partnership’s assets among different market sectors and trading approaches through the selection of the commodity trading advisors and by daily monitoring of their performance.  In addition, the Trading Advisors establish diversification guidelines, often set in terms of the maximum margin to be committed to positions in any one market sector or market-sensitive instrument.

Ceres monitors and controls the risk of the Partnership’s non-trading instrument, cash. Cash is the only Partnership investment directed by Ceres, rather than the Trading Advisors.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the management of Ceres, Ceres’ President (Ceres’ principal executive officer) and Chief Financial Officer (Ceres’ principal financial officer) have evaluated the effectiveness of the design and operation of the Partnership’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2013.  The Partnership’s disclosure controls and procedures are designed to provide reasonable assurance that information the Partnership is required to disclose in the reports that the Partnership files or submits under the Exchange Act are recorded, processed, summarized and reported within the time period specified in the applicable rules and forms.  Based on this evaluation, the President and Chief Financial Officer of Ceres have concluded that the disclosure controls and procedures of the Partnership were effective at June 30, 2013.

Changes in Internal Control over Financial Reporting

There have been no changes during the period covered by this quarterly report in the Partnership’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that have materially affected or are reasonably likely to materially affect the Partnership’s internal control over financial reporting.

- 38 -

Limitations on the Effectiveness of Controls

Any control system, no matter how well designed and operated, can provide reasonable (not absolute) assurance that its objectives will be met.  Furthermore, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

PART II.  OTHER INFORMATION

Item 1.  LEGAL PROCEEDINGS

On June 1, 2011, Morgan Stanley & Co. Incorporated converted from a Delaware corporation to a Delaware limited liability company.  As a result of that conversion, Morgan Stanley & Co. Incorporated is now named Morgan Stanley & Co. LLC (“MS&Co.” or the “Company”).

MS&Co. is a wholly-owned, indirect subsidiary of Morgan Stanley, a Delaware holding company.  Morgan Stanley files periodic reports with the Securities and Exchange Commission as required by the Securities Exchange Act of 1934, which include current descriptions of material litigation and material proceedings and investigations, if any, by governmental and/or regulatory agencies or self-regulatory organizations concerning Morgan Stanley and its subsidiaries, including MS&Co.  As a consolidated subsidiary of Morgan Stanley, MS&Co. does not file its own periodic reports with the SEC that contain descriptions of material litigation, proceedings and investigations.  As a result, we refer you to the “Legal Proceedings” section of Morgan Stanley’s SEC 10-K filings for 2012, 2011, 2010, 2009, and 2008.

In addition to the matters described in those filings, in the normal course of business, each of Morgan Stanley and MS&Co. has been named, from time to time, as a defendant in various legal actions, including arbitrations, class actions, and other litigation, arising in connection with its activities as a global diversified financial services institution.  Certain of the legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages.  Each of Morgan Stanley and MS&Co. is also involved, from time to time, in investigations and

- 40 -

proceedings by governmental and/or regulatory agencies or self-regulatory organizations, certain of which may result in adverse judgments, fines or penalties.  The number of these investigations and proceedings has increased in recent years with regard to many financial services institutions, including Morgan Stanley and MS&Co.

MS&Co. is a Delaware corporation with its main business office located at 1585 Broadway, New York, New York 10036.  Among other registrations and memberships, MS&Co. is registered as a futures commission merchant and is a member of the National Futures Association.

During the preceding five years, the following administrative, civil, or criminal actions pending, on appeal or concluded against MS&Co. or any of its principals are material within the meaning of CFTC Rule 4.24(l)(2) or 4.34(k)(2):

On June 2, 2009, Morgan Stanley executed a final settlement with the Office of the New York State Attorney General (“NYAG”) in connection with its investigation relating to the sale of auction-rate securities (“ARS”).  Morgan Stanley agreed, among other things to: (1) repurchase at par illiquid ARS that were purchased by certain retail clients prior to February 13, 2008; (2) pay certain retail clients that sold ARS below par the difference between par and the price at which the clients sold the securities; (3) arbitrate, under special procedures, claims for consequential damages by certain retail clients; (4) refund refinancing fees to certain municipal issuers of ARS; and (5) pay a total penalty of $35 million.  On August 13, 2008, Morgan Stanley reached an agreement in principle on substantially the same terms with the Office of the Illinois Secretary of State, Securities Department (on behalf of a task force of

- 41 -

other states under the auspices of the North American Securities Administrators Association) that would settle their investigations into the same matters.

On June 5, 2012, the Company consented to and became the subject of an Order Instituting Proceedings Pursuant to Sections 6(c) and 6(d) of the Commodity Exchange Act, as amended, Making Findings and Imposing Remedial Sanctions by the CFTC to resolve allegations related to the failure of a salesperson to comply with exchange rules that prohibit off-exchange futures transactions unless there is an Exchange for Related Position (“EFRP”).  Specifically, the CFTC found that from April 2008 through October 2009, the Company violated Section 4c(a) of the Commodity Exchange Act and Commission Regulation 1.38 by executing, processing and reporting numerous off-exchange futures trades to the Chicago Mercantile Exchange (“CME”) and Chicago Board of Trade (“CBOT”) as EFRPs in violation of CME and CBOT rules because those trades lacked the corresponding and related cash, OTC swap, OTC option, or other OTC derivative position.  In addition, the CFTC found that the Company violated CFTC Regulation 166.3 by failing to supervise the handling of the trades at issue and failing to have adequate policies and procedures designed to detect and deter the violations of the Act and Regulations.  Without admitting or denying the underlying allegations and without adjudication of any issue of law or fact, the Company accepted and consented to entry of findings and the imposition of a cease and desist order, a fine of $5,000,000, and undertakings related to public statements, cooperation and payment of the fine.  The Company entered into corresponding and related settlements with the CME and CBOT in which the CME found that the Company violated CME Rules 432.Q and 538 and fined the Company $750,000 and CBOT found that the Company violated CBOT Rules 432.Q and 538 and fined the Company $1,000,000.

On March 15, 2010, the Federal Home Loan Bank of San Francisco filed two complaints against the Company and other defendants in the Superior Court of the State of California. These actions are styled Federal Home Loan Bank of San Francisco v. Credit Suisse Securities (USA) LLC, et al., and Federal Home Loan Bank of San Francisco v. Deutsche Bank Securities Inc. et al., respectively. Amended complaints filed on June 10, 2010 allege that defendants made untrue statements and material omissions in connection with the sale to plaintiff of a number of mortgage pass-through certificates backed by securitization trusts containing residential mortgage loans. The amount of certificates allegedly sold to plaintiff by the Company in these cases was approximately $704 million and $276 million, respectively. The complaints raise claims under both the federal securities laws and California law and seek, among other things, to rescind the plaintiff’s purchase of such certificates. On July 29, 2011 and September 8, 2011, the court presiding over both actions sustained defendants’ demurrers with respect to claims brought under the Securities Act of 1933, as amended, and overruled defendants’ demurrers with respect to all other claims. At June 25, 2013, the current unpaid balance of the mortgage pass-through certificates at issue in these cases was approximately $345 million, and the certificates had incurred actual losses of approximately $2.8 million. Based on currently available information, the Company believes it could incur a loss for this action up to the difference between the $345 million unpaid balance of these certificates (plus any losses incurred) and their fair market value at the time of a judgment against the Company, plus pre- and post-judgment interest, fees and costs.

The Company may be entitled to be indemnified for some of these losses and to an offset for interest received by the plaintiff prior to a judgment.

On July 9, 2010 and February 11, 2011, Cambridge Place Investment Management Inc. filed two separate complaints against the Company and other defendants in the Superior Court of the Commonwealth of Massachusetts, both styled Cambridge Place Investment Management Inc. v. Morgan Stanley & Co., Inc., et al. The complaints assert claims on behalf of certain clients of plaintiff’s affiliates and allege that defendants made untrue statements and material omissions in the sale of a number of mortgage pass-through certificates backed by securitization trusts containing residential mortgage loans. The total amount of certificates allegedly issued by the Company or sold to plaintiff’s affiliates’ clients by the Company in the two matters was approximately $263 million. Plaintiff filed amended complaints on October 14, 2011, which raise claims under the Massachusetts Uniform Securities Act and seek, among other things, to rescind the plaintiff’s purchase of such certificates. On November 22, 2011, defendants filed a motion to dismiss the amended complaints. On March 12, 2012, the court denied defendants’ motion to dismiss with respect to plaintiff’s standing to bring suit. Defendants sought interlocutory appeal from that decision on April 11, 2012. On April 26, 2012, defendants filed a second motion to dismiss for failure to state a claim upon which relief can be granted, which the court denied, in substantial part, on October 2, 2012. At June 25, 2013, the current unpaid balance of the mortgage pass-through certificates at issue in these cases was approximately $216 million, and the certificates had incurred actual losses of approximately $109 million. Based on currently available information, the Company believes it could incur a loss for these actions of up to

the difference between the $216 million unpaid balance of these certificates (plus any losses incurred) and their fair market value at the time of a judgment against the Company, plus pre- and post-judgment interest, fees and costs. The Company may be entitled to be indemnified for some of these losses and to an offset for interest received by the plaintiff prior to a judgment.

On July 15, 2010, China Development Industrial Bank (“CDIB”) filed a complaint against the Company, which is styled China Development Industrial Bank v. Morgan Stanley & Co. Incorporated et al. and is pending in the Supreme Court of the State of New York, New York County (“Supreme Court of NY, NY County”). The complaint relates to a $275 million credit default swap referencing the super senior portion of the STACK 2006-1 CDO. The complaint asserts claims for common law fraud, fraudulent inducement and fraudulent concealment and alleges that the Company misrepresented the risks of the STACK 2006-1 CDO to CDIB, and that the Company knew that the assets backing the CDO were of poor quality when it entered into the credit default swap with CDIB. The complaint seeks compensatory damages related to the approximately $228 million that CDIB alleges it has already lost under the credit default swap, rescission of CDIB’s obligation to pay an additional $12 million, punitive damages, equitable relief, fees and costs. On February 28, 2011, the court presiding over this action denied the Company’s motion to dismiss the complaint and on March 21, 2011, the Company appealed that order.  On July 7, 2011, the appellate court affirmed the lower court’s decision denying the motion to dismiss. Based on currently available information, the Company believes it could incur a loss of up to approximately $240 million plus pre- and post-judgment interest, fees and costs.

Based on currently available information, the Company believes it could incur a loss in this action up to the difference between the $100 million unpaid balance of these certificates (plus any losses incurred) and their fair market value at the time of a judgment against the Company, plus pre- and post-judgment interest, fees and costs. The Company may be entitled to be indemnified for some of these losses and to an offset for interest received by the plaintiff prior to a judgment.

Financial Instruments [Abstract]

Financial Instruments

4.  Financial Instruments

The Partnership trades Futures Interests.  Subsequent to December 1, 2011, the Partnership trades futures and forwards through its investment in the Funds.  Futures and forwards represent contracts for delayed delivery of an instrument at a specified date and price.  Futures Interests are open commitments until settlement date, at which time they are realized.  They are valued at fair value, generally on a daily basis, and the unrealized gains and losses on open contracts (the difference between contract trade price and market price) are reported in the Partnership's Statements of Financial Condition as a net unrealized gain or loss on open contracts.  The resulting net change in unrealized gains and losses is reflected in the "Net change in unrealized depreciation on investment in BHM I, LLC", "Net change in unrealized appreciation (depreciation) on investment in PGR Master Fund" and "Net change in unrealized appreciation (depreciation) on investment in MB Master Fund" on open contracts from one period to the next on the Statements of Income and Expenses.  The fair value of exchange-traded futures, options and forward contracts is determined by the various futures exchanges, and reflects the settlement price for each contract as of the close of business on the last business day of the reporting period.

The fair value of foreign currency forward contracts is extrapolated on a forward basis from the spot prices quoted as of approximately 3:00 P.M. (E.T.) of the last business day of the reporting period from various exchanges.  The fair value of non-exchange-traded foreign currency option contracts is calculated by applying an industry standard model application for options valuation of foreign currency options, using as input the spot prices, interest rates, and option implied volatilities quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period.  Risk arises from changes in the value of these contracts and the potential inability of counterparties to perform under the terms of the contracts.  There are numerous factors which may significantly influence the fair value of these contracts, including interest rate volatility.

The Partnership may invest in affiliated underlying funds.  Relevant authoritative guidance permits, as a practical expedient, the Partnership to measure the fair value of its investment in affiliated underlying funds on the basis of the net asset value per share of such investments (or the equivalent) if the net asset value per share of such investments (or the equivalent) is calculated in a manner consistent with the measurement principles of applicable authoritative guidance as of the Partnership's reporting date.  The fair value of each affiliated underlying fund is based on the information provided by the affiliated underlying fund which reflects the Partnership's share of the fair value of the net assets of the affiliated underlying fund (i.e., the practical expedient is used).

The fair value of exchange-traded contracts is based on the settlement price quoted by the exchange on the day with respect to which fair value is being determined.  If an exchange-traded contract could not have been liquidated on such day due to the operation of daily limits or other rules of the exchange, the settlement price will be equal to the settlement price on the first subsequent day on which the contract could be liquidated.   The fair value of off-exchange-traded contracts is based on the fair value quoted by the counterparty.

The Partnership's contracts are accounted for on a trade-date basis.  The Partnership accounts for its derivative investments as described in Note 5. Derivatives and Hedging as required by the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC").A derivative is defined as a financial instrument or other contract that has all three of the following characteristics:

1)   a) One or more "underlyings" and b) one or more "notional amounts" or payment provisions or both;

2)   Requires no initial net investment or a smaller initial net investment than would be required for other types of contracts that would be expected to have a similar response relative to changes in market factors; and

3)   Terms that require or permit net settlement.

Generally, derivatives include futures, forward, swaps or options contracts, and other financial instruments with similar characteristics such as caps, floors, and collars.

The futures, forwards and options traded by the Partnership involve varying degrees of related market risk.  Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership's open positions, and consequently in its earnings, whether realized or unrealized, and cash flow.  Gains and losses on open positions of exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are settled daily through variation margin.  Gains and losses on off-exchange-traded forward currency contracts are settled on termination of the contract.  Gains and losses on off-exchange-traded forward currency options contracts are settled upon an agreed-upon settlement date.

Income Taxes

8.  Income Taxes

No provision for income taxes has been made in the accompanying financial statements, as partners are individually responsible for reporting income or loss based upon their respective share of the Partnership's revenues and expenses for income tax purposes. The Partnership files U.S. federal and state tax returns.

The guidance issued by the FASB on income taxes clarifies the accounting for uncertainty in income taxes recognized in the Partnership's financial statements, and prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken.  The Partnership has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements as of June 30, 2013 and December 31, 2012.  If applicable, the Partnership recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in other expenses in the Statements of Income and Expenses.  Generally, the 2009 through 2012 tax years remain subject to examination by U.S. federal and most state tax authorities.  No income tax returns are currently under examination.

In June 2013, the FASB issued ASU 2013-08, "Financial Services – Investments Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements".  ASU 2013-08 changes the approach to the investment company assessment, requires non-controlling ownership interests in other investment companies to be measured at fair value, and requires additional disclosures about the investment company's status as an investment company.  The amendments are effective for interim and annual reporting periods beginning after December 15, 2013.  The Partnership is currently evaluating the impact this pronouncement would have on the financial statements.

Fair Value Measurements and Disclosures [Abstract]

Fair Value Measurements and Disclosures

6.  Fair Value Measurements and Disclosures

On October 1, 2012, the FASB issued Accounting Standards Update ("ASU") 2012-04 "Technical Corrections and Improvements", which makes minor technical corrections and clarifications to ASC 820, "Fair Value Measurements and Disclosures". When the FASB issued Statement 157 (codified in ASC 820), it conformed the use of the term "fair value" in certain pre-Codification standards but not others. ASU 2012-04 conforms the term's use throughout the ASC "to fully reflect the fair value measurement and disclosure requirements" of ASC 820. The ASU also amends the requirements that must be met for an investment company to qualify for the exemption from presenting a statement of cash flows.  Specifically, it eliminates the requirements that substantially all of an entity's investments be carried at "market value" and that the investments be highly liquid. Instead, it requires substantially all of the entity's investments to be carried at "fair value" and classified as Level 1 or Level 2 measurements under ASC 820. The amendments are effective for fiscal periods beginning after December 15, 2012. The adoption of this ASU did not have a significant impact on the Partnership's financial statements.

Financial instruments are carried at fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  Assets and liabilities carried at fair value are classified and disclosed in the following three levels: Level 1 - unadjusted quoted market prices in active markets for identical assets and liabilities; Level 2 - inputs other than unadjusted quoted market prices that are observable for the asset or liability, either directly or indirectly (including unadjusted quoted market prices for similar investments, interest rates and credit risk); and Level 3 - unobservable inputs for the asset or liability (including the Partnership's own assumptions used in determining the fair value of investments).  In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy.  In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.  The Partnership's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment.

The Partnership's assets and liabilities measured at fair value on a recurring basis are summarized in the following tables by the type of inputs applicable to the fair value measurements.

June 30, 2013	Unadjusted Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)			Total

During the period January 1, 2013 to June 30, 2013, and the twelve months ended December 31, 2012, there were no Level 3 assets and liabilities and there were no transfers of assets or liabilities between Level 1 and Level 2.
