Basis Of Presentation and General Information

1.	Basis of Presentation and General Information

Capital Product Partners L.P. (the “Partnership”) was formed on January 16, 2007, under the laws of the Marshall Islands. The Partnership is an international shipping company. Its fleet of twenty seven modern high specification vessels consists of four Suezmax crude oil tankers, eighteen modern medium range tankers all of which are classed as IMO II/III vessels, four post panamax container carrier vessels, and one capesize bulk carrier. Its vessels are capable of carrying a wide range of cargoes, including crude oil, refined oil products, such as gasoline, diesel, fuel oil and jet fuel, edible oils and certain chemicals such as ethanol as well as dry cargo and containerized goods under short-term voyage charters and medium to long-term time and bareboat charters

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all the information and notes required by U.S. GAAP for complete financial statements. These statements and the accompanying notes should be read in conjunction with the Company's Annual Report on Form 20-F for the fiscal year ended December 31, 2012, filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 5, 2013.

These unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation of the Partnership's financial position, results of operations and cash flows for the periods presented. Operating results for the six-month period ended June 30, 2013 are not necessarily indicative of the results that might be expected for the fiscal year ending December 31, 2013.

Significant Accounting Policies

2.	Significant Accounting Policies

A discussion of the Partnership's significant accounting policies can be found in the Partnership's Consolidated Financial Statements included in the Annual Report on Form 20-F for the year ended December 31, 2012 (the “Consolidated Financial Statements for the year ended December 31, 2012”). The Company amended its significant accounting policies in order to include a new policy for deferred dry docking costs.

Deferred dry docking costs: The Company's vessels are required to be dry docked every 30 to 60 months for major repairs and maintenance that cannot be performed while the vessels are under operation. For the vessels that were operated under the floating fee management agreement and Crude's management agreement (Note 4) the Company has adopted the deferral method of accounting for dry-dock activities whereby costs incurred are deferred and amortized on a straight-line basis over the period until the next scheduled dry-dock activity.

Acquisitions

3.	Acquisitions

a. Hercules Container Carrier S.A. (M/V Aristotelis)

On March 20, 2013, the Partnership acquired the shares of Hercules Container Carrier S.A., the vessel owning company of the M/V Aristotelis (renamed Hyundai Premium) (“Hercules”) from Capital Maritime and Trading Corp. (“CMTC”) for a total consideration of $65,000 following the unanimous recommendation of the conflicts committee and the unanimous approval of the board of directors. The vessel at the time of her acquisition by the Partnership was fixed on a twelve year time charter, with Hyundai Merchant Marine Co Ltd (“Hyundai”). The time charter commenced in March 2013 and the earliest expiration date under the charter is in January 2025.

The Partnership accounted for the acquisition of Hercules as an acquisition of a business. All assets and liabilities of Hercules except the vessel, necessary permits and time charter agreement, were retained by CMTC. The purchase price of the acquisition has been allocated to the identifiable assets acquired, with the excess of the fair value of assets acquired over the purchase price recorded as a gain from bargain purchase.

•

Purchase Price

The total purchase consideration of $65,000 was funded by $27,000 through a draw-down from the Partnership's $350,000 credit facility (Note 7), by $36,268 representing part of the net proceeds from the issuance of 9,100,000 Partnership's Class B Convertible Preferred Units in March 2013 (Note 9) and by $1,732 from the Partnership's available cash.

•

Acquisition related costs

There were no costs incurred in relation to the acquisition of Hercules.

•

Purchase price allocation

The allocation of the purchase price to acquired identifiable assets was based on their estimated fair values at the date of acquisition.

The fair value allocated to each class of identifiable assets of Hercules and the gain from bargain purchase recorded as non operating income, net in the Partnership's unaudited condensed consolidated statements of comprehensive income for the six month period ended June 30, 2013 was calculated as follows:


	As of March 20, 2013
Vessel	$	54,000
Above market acquired time charter	$	19,707
Identifiable assets	$	73,707
Purchase price		(65,000	)
Gain from bargain purchase	$	8,707

After a subsequent review and reassessment of valuation methods and procedures of the $73,707 fair value amount for identifiable assets acquired, the Partnership concluded that its measurements for the assets acquired appropriately reflect consideration of all available information that existed as of the acquisition date. Therefore, the Partnership recorded a gain from bargain purchase of $8,707 in its unaudited condensed consolidated statements of comprehensive income, in accordance with Accounting Standard Codification (“ASC”) Subtopic 805-30 “Business Combinations, Goodwill or Gain from Bargain Purchase, Including Consideration Transferred” as of the Hercules acquisition date.

•

Identifiable intangible assets

The following table sets forth the component of the identifiable intangible asset acquired with the purchase of Hercules which is being amortized over its duration on a straight-line basis as a reduction of revenue:


Intangible assets	As of March 20, 2013		Duration of time charter acquired
Above market acquired time charter	$	19,707	11.8 years

The fair value of the above market time charter acquired was determined as the difference between the time charter rate at which the vessel was fixed at and market rate for comparable charter as provided by independent third parties on the business combination date discounted at a WACC of approximately 11%.

Total revenues and net income of M/V Aristotelis since its acquisition by the Partnership were $2,583 and $1,305 respectively and are included in the Partnership's unaudited condensed consolidated statements of comprehensive income for the six months period ended June 30, 2013.

•

Pro Forma Financial Information

.The supplemental pro forma financial information was prepared using the acquisition method of accounting and is based on the following:

	•		The Partnership's actual results of operations for the six month period ended June 30, 2013

	•		Pro forma results of operations of Hercules for the period from its vessel's delivery from the shipyard on March 11, 2013 (vessel inception) to March 20, 2013 as if Aristotelis was operating under post acquisition revenue and cost structure.

The combined results do not purport to be indicative of the results of the operations which would have resulted had the acquisition been effected at beginning of the applicable period noted above, or the future results of operations of the combined entity.

The following table summarizes total net revenues; net income and net income per common unit of the combined entity had the acquisition of Aristotelis occurred on March 11, 2013 (vessel inception):

	For the six months period ended June 30, 2013
Total revenues	$	81,957
Partnership's net income	$	64,424
Partnership's net income available to preferred unit holders	$	10,540
General Partner's interest in Partnership's net income	$	1,078
Common unit holders interest in Partnership's net income	$	52,806
Pro-forma weighted average of Partnership's common units outstanding - basic		68,385,001
Net income per common unit basic	$	0.76
Pro-forma weighted average of Partnership's common units outstanding - diluted		89,980,394
Net income per common unit diluted	$	0.71

b. Iason Container Carrier S.A. (M/V Attalos)

On 27 March 2013, the M/V Attalos (renamed Hyundai Paramount) (“Iason”) was delivered to CMTC from a shipyard and on the same date the Partnership acquired the shares of Iason Container Carrier S.A., the vessel owning company of Iason from CMTC for a total consideration of $65,000 following the unanimous recommendation of the conflicts committee and the unanimous approval of the board of directors. At the time of her acquisition by the Partnership the vessel was fixed on a twelve year time charter, with Hyundai Merchant Marine Co Ltd (“Hyundai”). The time charter commenced in April 2013 and the earliest expiration date under the charter is in February 2025.

The Partnership accounted for the acquisition of Iason as an acquisition of a business. All assets and liabilities of Iason except the vessel, necessary permits and time charter agreement, were retained by CMTC. The purchase price of the acquisition has been allocated to the identifiable assets acquired, with the excess of the fair value of assets acquired over the purchase price recorded as a gain from bargain purchase.

•

Purchase Price

The total purchase consideration of $65,000 was funded by $27,000 through a draw-down from the Partnership's $350,000 credit facility (Note 7), by $36,267 representing part of the net proceeds from the issuance of Partnership's Class B Convertible Preferred Units in March 2013 (Note 9) and by $1,733 from the Partnership's available cash.

•

Acquisition related costs

There were no costs incurred in relation to the acquisition of Iason.

•

Purchase price allocation

The allocation of the purchase price to acquired identifiable assets was based on their estimated fair values at the date of acquisition.

The fair value allocated to each class of identifiable assets of Iason and the gain from bargain purchase recorded as non operating income, net in the Partnership's unaudited condensed consolidated statements of comprehensive income for the six month period ended June 30, 2013 was calculated as follows:


	As of March 27, 2013
Vessel	$	54,000
Above market acquired time charter	$	19,768
Identifiable assets	$	73,768
Purchase price	$	(65,000	)
Gain from bargain purchase	$	8,768

After a subsequent review and reassessment of valuation methods and procedures of the $73,768 fair value amount for identifiable assets acquired, the Partnership concluded that its measurements for the assets acquired appropriately reflect consideration of all available information that existed as of the acquisition date. Therefore, the Partnership recorded a gain from bargain purchase of $8,768 in its unaudited condensed consolidated statements of comprehensive income, in accordance with ASC Subtopic 805-30 “Business Combinations, Goodwill or Gain from Bargain Purchase, Including Consideration Transferred” as of the Iason acquisition date.

•

Identifiable intangible assets

The following table sets forth the component of the identifiable intangible asset acquired with the purchase of Iason which is being amortized over its duration on a straight-line basis as a reduction of revenue:


Intangible assets	As of March 27, 2013		Duration of time charter acquired
Above market acquired time charter	$	19,768	11.8 years

Total revenues and net income of Atalos since its acquisition by the Partnership were $2,156 and $969 respectively and included in the Partnership's unaudited condensed consolidated statements of comprehensive income for the six month period ended June 30, 2013.

•

Pro Forma Financial Information

There is no pro forma financial information available in relation to the acquisition of Iason as its vessel was under construction up to the date of her acquisition by the Partnership.

Transactions with Related Parties

4.	Transactions with Related Parties

The Partnership and its subsidiaries, have related-party transactions with the Capital Shipmanagement Corp. (the “Manager”), due to certain terms of the following three different types of management agreements.

Fixed fee management agreement: At the time of the completion of the IPO the Partnership entered into an agreement with its Manager , according to which the Manager provides the Partnership with certain commercial and technical management services for a fixed daily fee per managed vessel which covers the commercial and technical management services, the respective vessels' operating costs such as crewing, repairs and maintenance, insurance, stores, spares, and lubricants as well as the cost of the first special survey or next scheduled dry-docking, of each vessel. In addition to the fixed daily fees payable under the management agreement, the Manager is entitled to supplementary compensation for additional fees and costs (as defined in the agreement) of any direct and indirect additional expenses it reasonably incurs in providing these services, which may vary from time to time. The Partnership also pay a fixed daily fee per bareboat chartered vessel in its fleet, mainly to cover compliance and commercial costs, which include those costs incurred by the manager to remain in compliance with the oil majors' requirements, including vetting requirements;

Floating fee management agreement: On June 9, 2011, the Partnership entered into an agreement with its Manager based on actual expenses with an initial term of five years per managed vessel. Under the terms of this agreement the Partnership compensates its Manager for expenses and liabilities incurred on the Partnership's behalf while providing the agreed services, including, but not limited to, crew, repairs and maintenance, insurance, stores, spares, lubricants and other operating costs. Costs and expenses associated with a managed vessel's next scheduled dry docking are borne by the Partnership and not by the Manager. The Partnership also pays its Manager a daily technical management fee per managed vessel that is revised annually based on the United States Consumer Price Index; and

Crude Carriers Corp. (“Crude”) management agreement: On September 30, 2011, the Partnership completed the acquisition of Crude. The five crude tanker vessels the Partnership acquired as part of the Crude's acquisition continue to be managed under a management agreement entered into in March 2010 with the Manager whose initial term expires on December 31, 2020. Under the terms of this agreement the Partnership compensates the Manager for all of its expenses and liabilities incurred on the Partnership's behalf while providing the agreed services, including, but not limited to, crew, repairs and maintenance, insurance, stores, spares, lubricants and other operating and administrative costs. The Partnership also pays its Manager the following fees:

(a) a daily technical management fee per managed vessel that is revised annually based on the United States Consumer Price Index;

(b) a sale and purchase fee equal to 1% of the gross purchase or sale price upon the consummation of any purchase or sale of a vessel acquired by Crude ; and

(c) a commercial services fee equal to 1.25% of all gross charter revenues generated by each vessel for commercial services rendered.

The Manager has the right to terminate the Crude management agreement and, under certain circumstances, could receive substantial sums in connection with such termination. As of March 2013 this termination fee had been adjusted from $9,000 to $9,654.

All the above three agreements will constitute the “Management Agreements”.

Under the terms of the fixed fee management agreement, the Manager charged the Partnership for additional fees and costs, relating to insurances deductibles, vetting, and repairs and spares that related to unforeseen events. For the six months period ended June 30, 2013 and 2012 such fees amounted to $389 and $1,016 respectively.

On April 4, 2007, the Partnership entered into an administrative services agreement with the Manager, pursuant to which the Manager will provide certain administrative management services to the Partnership such as accounting, auditing, legal, insurance, IT, clerical, investor relations and other administrative services. Also the Partnership reimburses CGP for all expenses which are necessary or appropriate for the conduct of the Partnership's business. The Partnership reimburses the Manager and CGP for reasonable costs and expenses incurred in connection with the provision of these services after the Manager submits to the Partnership an invoice for such costs and expenses, together with any supporting detail that may be reasonably required. These expenses are included in general and administrative expenses in the unaudited condensed consolidated statements of comprehensive income.

The Partnership follows the accounting guidance for derivative instruments which requires disclosure that establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosure about fair value measurements. This guidance enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing hierarchy for ranking the quality and reliability of the information used to determine fair values. The statement requires that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date;

Level 2: Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly;

Level 3: Inputs are unobservable inputs for the asset or liability.

The Partnership's interest rate swap agreements, entered into pursuant to its loan agreements, are based on LIBOR swap rates. LIBOR swap rates are observable at commonly quoted intervals for the full terms of the swaps and therefore are considered Level 2 items. The fair values of the interest rate swap determined through Level 2 of the fair value hierarchy are derived principally from or corroborated by observable market data. Inputs include quoted prices for similar assets, liabilities (risk adjusted) and market-corroborated inputs, such as market comparable, interest rates, yield curves and other items that allow value to be determined. Fair value of the interest rate swaps is determined using a discounted cash flow method based on market-base LIBOR swap yield curves. The fair value of the Partnership's interest rate swaps is the estimated value of the swap agreements at the reporting date, taking into account current interest rates and the forward yield curve and the creditworthiness of the Partnership and its counterparties.

Since March 31, 2012 and May 23, 2012 two out of three interest rate swaps did not qualify as cash flow hedges and the changes in their fair value was recognized in the unaudited condensed consolidated statements of comprehensive income whilst the third interest rate swap agreement qualified as a cash flow hedge and the changes in its fair value is recognized in accumulated other comprehensive loss. As a result the amount of $1,400 and $50, which was part of the Partnership's accumulated other comprehensive loss (“OCL”) as of March 31, 2012 and May 23, 2012 respectively, were attributable to the two ineffective hedges and were being amortized over their respective remaining term up to their maturity date March 27, 2013 and March 28, 2013, respectively in the Partnership's unaudited condensed consolidated statements of comprehensive income by using the effective interest rate method. For the six month period ended June 30, 2013 and 2012 the Partnership recorded an expense of $363 and $362 from the above amortization respectively.

The net result of the accumulated OCL amortization and the change of the fair value of certain interest rate swap agreements of $ 4 and $1,447 is presented under other non operating income (expense) net as a “Gain on interest rate swap agreement” in the Partnership's consolidated statements of comprehensive income for the six months period ended June 30, 2013 and June 30, 2012, respectively.

Omnibus Incentive Compensation Plan

a.	Partnership's Omnibus Incentive Compensation Plan

On April 29, 2008, the Board of Directors approved the Partnership's Omnibus Incentive Compensation Plan (the “Plan”) according to which the Partnership may issue a limited number of awards, not to exceed 500,000 units. The Plan was amended on July 22, 2010 increasing the aggregate number of restricted units issuable under the Plan to 800,000. The Plan is administered by the General Partner as authorized by the Board of Directors. The persons eligible to receive awards under the Plan are officers, directors, and executive, managerial, administrative and professional employees of the Manager, or CMTC, or other eligible persons (collectively, “key persons”) as the General Partner (“CGP”), in its sole discretion, shall select based upon such factors as it deems relevant. Members of the Board of Directors are considered to be employees of the Partnership (“Employees”) for the purposes of recognition of equity compensation expense, while employees of the Manager, CMTC and other eligible persons under the plan are not considered to be employees of the Partnership (“Non-Employees”). Awards may be made under the Plan in the form of incentive stock options, non-qualified stock options, stock appreciation rights, dividend equivalent rights, restricted stock, unrestricted stock, restricted stock units and performance shares.

On August 25 and 31, 2010 CGP awarded 448,000 and 347,200 unvested units to Employees and Non-Employees, respectively. Awards granted to certain Employees vest in three equal annual installments. The remaining awards will vest on August 31, 2013.

All unvested units are conditional upon the grantee's continued service as Employee and/or Non-Employee until the applicable vesting date. The unvested units will accrue distributions as declared and paid which will be retained by the custodian of the Plan until the units vest at which time they are payable to the grantee. As unvested unit grantees accrue distributions on awards that are expected to vest, such distributions are charged to Partner's capital.

On March 1, 2010 Crude adopted an equity incentive plan according to which Crude issued 399,400 shares out of 400,000 restricted shares that were authorized. Members of the Board of Directors were considered to be employees of Crude (“Employees”), while employees of Crude's affiliates and other eligible persons under this plan were not considered to be employees of Crude (“Non-Employees”). Awards granted to certain Employees vest in three equal annual installments. The remaining awards will vest on August 31, 2013.

All unvested shares are conditional upon the grantee's continued service as Employee and/or Non-Employee until the applicable vesting date. The unvested shares will accrue dividends as declared and paid, which will be retained by the custodian of Crude's equity incentive plan until the shares vest, at which time they are payable to the grantee. As unvested shares grantees accrue dividends on awards that are expected to vest, such dividends were charged to Stockholders' equity prior to Crude's acquisition and are charged to the Partner's capital subsequently to the acquisition.

c.	Acquisition of Crude by the Partnership

Upon the completion of the acquisition of Crude by the Partnership on September 30, 2011, the Crude's Equity Incentive Plan existing that date was incorporated into the Partnership's Plan at a ratio of 1.56 common Partnership's unit for each Crude share. The 205,000 unvested shares of Crude's Employee award converted to 319,800 Partnership's unvested units and the 194,400 unvested shares of Crude's Non-Employee award converted to 303,264 Partnership's unvested units. The terms and conditions of both plans are significantly the same and remained unchanged after the acquisition, with the exception of 20,000 Crude shares, which were converted to 31,200 Partnership's units upon the completion of the acquisition. These Crude shares were held by those members of the Crude's Independent Committee who were not designated by Crude to serve as a member of the Partnership board of directors and were vested in full immediately upon the consummation of the acquisition on September 30, 2011.

There were no forfeitures of awards during the period ended June 30, 2013. The Partnership estimates the forfeitures of unvested units to be immaterial. The Partnership will, however, re-evaluate the reasonableness of its assumption at each reporting period. As of June 30, 2013, the unvested units accrued $ 2,253 of distributions.

Unvested on June 30, 2013		335,535		2,504		650,464		4,736

For the six - month period ended June 30, 2013 the equity compensation expense that has been charged against income was $907 for the employee awards and $1,832 for the non-employee awards, this expense has been included in general and administrative expenses.

As of June 30, 2013, there was $309 of total unrecognized compensation cost related to unvested equity compensation arrangements granted to Employees under the Plan based on:

•

the grant date unit price of $8.08 on August 25, 2010 for the Employees awards that existed before the acquisition of Crude; and

•

the amortization of the fair value of equity compensation expense for Crude's Employees awards attributable to post-combination services determined upon the completion of the acquisition of Crude.

That cost is expected to be recognized over the remaining vesting period of 0.2 years.

As of June 30, 2013, there was $753 of total unrecognized compensation cost related to unvested equity compensation arrangements granted to Non-Employees under the Plan, valued based on the closing unit price of $9.28 on June 30, 2013. That cost is expected to be recognized over the remaining vesting period of 0.2 years.

The Partnership has used the straight-line method to recognize the cost of the awards.

Net Income Per Unit

The general partner's, common unit holders' and subordinated unitholders' interests in net income are calculated as if all net income for periods subsequent to April 4, 2007, were distributed according to the terms of the Partnership's Agreement, regardless of whether those earnings would or could be distributed. The Partnership Agreement does not provide for the distribution of net income; rather, it provides for the distribution of available cash, which is a contractually-defined term that generally means all cash on hand at the end of each quarter after establishment of cash reserves established by the Partnership's board of directors to provide for the proper resources for the Partnership's business. Unlike available cash, net income is affected by non-cash items. The Partnership follows the guidance relating to the Application of the Two-Class Method and its application to Master Limited Partnerships which considers whether the incentive distributions of a master limited partnership represent a participating security when considered in the calculation of earnings per unit under the Two-Class Method. This guidance also considers whether the partnership agreement contains any contractual limitations concerning distributions to the incentive distribution rights that would impact the amount of earnings to allocate to the incentive distribution rights for each reporting period.

Under the Partnership Agreement, the holder of the incentive distribution rights in the Partnership, which is currently the CGP, assuming that there are no cumulative arrearages on common unit distributions, has the right to receive an increasing percentage of cash distributions after the minimum quarterly distribution.

Excluding the non-cash gain from bargain purchase, as this was not distributed to the Partnership's unit holders for the six months period ended June 30, 2013 the Partnership's net income for the six months periods ended June 30, 2013 and 2012, did not exceed the First Target Distribution Level, and as a result, the assumed distribution of net income did not result in the use of increasing percentages to calculate CGP's interest in net income.

The two class method was used to calculate EPU as follows:

Gain on sale of claim

On November 14, 2012, Overseas Shipholding Group Inc. ("OSG") and certain of its subsidiaries made a voluntary filing for relief under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the District of Delaware (the "Bankruptcy Court"). The Partnership had three IMO II/III Chemical/Product tankers (M/T Alexandros II, M/T Aristotelis II and M/T Aris II) or (the “Vessels”), all built in 2008 by STX Offshore and Shipbuilding Co. Ltd. with long term bareboat charters to subsidiaries of OSG (“Original Charter Contracts” or “Rejected Charters”).

After discussions with OSG, the Partnership agreed to enter into new charter contracts (“New Charter Contracts”) with OSG on substantially the same terms as the Original Charter Contracts, but at a bareboat rate of $6.3 per day per vessel instead of $13.0 per day per vessel as per the Original Charter Contracts. The new charters were approved by the Bankruptcy Court on March 21, 2013 and were effective as of March 1, 2013. On the same date, the Bankruptcy Court also rejected the Original Charter Contracts as of March 1, 2013. Rejection of each charter constitutes a material breach of such charter. On May 24, 2013, the Partnership filed claims (the "Claims") against each of the charterers and their respective guarantors for damages resulting from the rejection of each of the Original Charter Contracts, including, among other things, the difference between the reduced amount of the New Charter Contracts and the amount due under each of the Rejected Charters. The total claim amount of the three claims stands at $54,096 (“Total Claim Amount”).

The Partnership unconditionally and irrevocably sold, transferred and assigned to Deutsche Bank 100% of its right, title, interest, claims and causes of action in and to arising in connection with all three of the claims that the vessel-owning subsidiaries have against OSG, via Assignment Agreements signed on June 25, 2013, thus releasing the Partnership of any payments or distributions of money or property in respect of the claim to be delivered or made to Deutsche Bank. In connection with the Assignment Agreements, on July 2, 2013, Deutsche Bank filed with the Bankruptcy Court six separate Evidences of Transfer of Claim, each pertaining to the Partnership's vessel-owning subsidiaries' claims against each charterer party to the original three charter agreements and each respective guarantor thereof.

The total amount to be received by Deutsche Bank, the largest part of which has been already paid, is dependent on the actual claim amount allowed by the Bankruptcy Court. The Partnership may be required to refund a portion of the purchase price or may receive an additional payment from Deutsche Bank. Pursuant to the Assignment Agreements, the Partnership received on June 26, 2013 from Deutsche Bank an amount of $32,000 as part payment for the assignment of the three claims (compared to $39,219 that would be the amount paid to the Partnership based on the purchase price should the full claim amount of $54,096 be allowed by the Bankruptcy Court). In addition, and pursuant to the Assignment Agreements, the Partnership in no event shall be required to refund more than $9,000 to Deutsche Bank except in the case of breach by the Partnership of its representations, warranties, covenants, agreements or indemnities set forth in the Assignment Agreements.

The Partnership has determined that it is not probable that the amount up to $9,000 will need to be paid back to Deutsche Bank and further believes that such amount cannot be reasonably estimated at this time. Accordingly, the Partnership has determined that the amount of $9,000 shall not be accrued by a charge to the unaudited condensed consolidated statements of comprehensive income for the six month period ended June 30, 2013. Additionally, the Partnership believes that it is not appropriate at this time to recognize an amount up to $7,219 that could potentially be paid to the Partnership by Deutsche Bank should the Bankruptcy Court allow the claim for more than an aggregate amount of $44,138, as this amount is deemed to be a gain contingency and would only be recognized once the contingency is resolved. Consequently, the Partnership has recorded the amount of $32,000 in its unaudited condensed consolidated statement of comprehensive income as “Gain on sale of claim”.

13. Commitments and Contingencies

Various claims, suits, and complaints, including those involving government regulations and product liability, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, agents, insurance and other claims with suppliers relating to the operations of the Partnership's vessels. The Partnership is not aware of any such claims or contingent liabilities, which should be disclosed, or for which a provision should be established in the accompanying unaudited condensed consolidated financial statements.

The Partnership accrues for the cost of environmental liabilities when management becomes aware that a liability is probable and is able to reasonably estimate the probable exposure. Currently, the Partnership is not aware of any such claims or contingent liabilities, which should be disclosed, or for which a provision should be established in the accompanying unaudited condensed consolidated financial statements.
