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 thirty three modern high specification vessels consists of four suezmax crude oil tankers, twenty modern medium range tankers all of which are classed as IMO II/III vessels, eight 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, 2014, filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 26, 2015.

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 all 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, 2015 are not necessarily indicative of the results that might be expected for the fiscal year ending December 31, 2015.

Immaterial reclassification to correct prior period presentation: The reclassification reflects the value of the conversion of 350,000 class B units into common units during the six month period ended June 30, 2014 which were not reflected in the unaudited condensed consolidated statement of changes in partners' capital for the six month period ended June 30, 2014. This error was identified prior to December 31, 2014 and correctly presented in the Partnership's Consolidated Financial Statements included in the Annual Report on Form 20-F for the year ended December 31, 2014 (the “Consolidated Financial Statements for the year ended December 31, 2014”). Total partners' capital remained unchanged as the reclassification impacted only the Partnership's Limited Partners - Common and the Partnership's Limited Partners - Preferred, and no other financial statement line items were impacted by these reclassifications. This reclassification resulted in an increase of $2,787 to the Partnership's Limited Partners—Common and a decrease of $2,787 to the company's Limited Partners—Preferred.

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. There have been no changes to these policies in the six month period ended June 30, 2015.

Recent accounting pronouncements: On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No 2014-09, Revenue From Contracts With Customers, which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This standard is effective for public entities with reporting periods beginning after December 15, 2016. Early adoption is not permitted. The Partnership is currently evaluating the impact, if any, of the adoption of this new standard.

In April 2015, the FASB issued ASU 2015-03 Simplifying the Presentation of Debt Issuance Costs. To simplify presentation of debt issuance costs, the amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. This standard is effective for public entities with reporting periods beginning after December 15, 2015. Early adoption is permitted. The Partnership believes that the implementation of this standard will only affect the presentation of debt issuance costs which will be shown as a direct deduction of the related debt instead of under non-current assets in the accompanying balance sheets and has not elected the early adoption.

Transactions with Related Parties

3.	Transactions with Related Parties

The Partnership and its subsidiaries have related-party transactions with Capital Ship Management Corp. (the “Manager” or “CSM”), 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 pays 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 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 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 2015 this termination fee was adjusted to $9,760.

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

Under the terms of the fixed fee management agreement, the Manager charges the Partnership for additional fees and costs, relating to insurances deductibles, vetting, and repairs and spares that related to unforeseen events. For the six month periods ended June 30, 2015 and 2014 such fees amounted to $268 and $640 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 Capital General Partner (“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.

4. Fixed assets

(a) Advances for vessels under construction - related party

An analysis of advances for vessels under construction - related party is as follows:


	Advances for vessels under construction-related party
Balance as at January 1, 2015	$	66,641
Additions		—
Transfer to vessels		(30,323	)
Balance as at June 30, 2015	$	36,318

On July 24, 2014, the Partnership entered into a Master Agreement with CMTC to acquire five vessel owning companies that owned five under construction vessels (the “Newbuildings”) subject to the amendment of the partnership agreement to reset the target distributions to holders of the incentive distribution rights (the “IDR”) (Note 7).

As the reset of the IDR was a pre-condition for the acquisition of the vessels, the amount of $ 36,417, representing the difference between the fair value of the respective Newbuildings at the time of the approval of this transaction in August 2014 at the Partnership's annual general meeting of $ 347,917 and the contractual cash consideration of $ 311,500, is considered to be the deemed equity contribution and thus the fair value of the reset of the IDR. The fair value of the IDR reset has been accounted for in Partner's capital and in the Partnership's unaudited condensed consolidated balance sheets as “Advances for vessels under construction - related party”. The fair value of the new buildings amounting to $ 347,917 was based on the average of three valuations obtained from three independent shipbrokers.

The Newbuildings comprise two 50,000 Dead Weight Tonnage (“dwt”) product carriers and three 9,288 Twenty feet Equivalent Unit (“TEU”) post-panamax container carriers. Following the successful follow-on offering in September 2014 (Note 7), the Partnership made on September 10, 2014, an advance payment to CMTC of $30,224 in connection with the above acquisitions, and was presented as “Advances for vessels under construction - related party” in the Partnership's Consolidated Financial Statements for the year ended December 31, 2014. According to the Master Agreement the Partnership also has the right of first refusal to acquire six additional new building product tanker vessels with expected delivery dates in 2015 and 2016.

During the six month period ended June 30, 2015 the Partnership acquired from CMTC the shares of the three out of the five vessel owning companies (Note 4b). As a result, as at June 30, 2015, the amount of $36,318 consisted of advances of $15,818 that the Partnership paid to CMTC for the acquisition of the remaining two vessel owning companies and the fair value from the reset of the IDR of $20,500 that was applicable to these two vessels, and is presented as “Advances for vessels under construction-related party” in the Partnership's unaudited condensed consolidated balance sheets as of June 30, 2015.

(b) Vessels, net

An analysis of vessels is as follows:

	Vessel Cost	Accumulated depreciation	Net book value
Balance as at January 1, 2015	$1,396,735	$(276,665)	$1,120,070
Acquisition and improvements	134,173	-	134,173
Transfer from Advances for vessels under construction - related party	30,323	-	30,323
Depreciation for the period	-	(29,013	) (29,013)
Balance as at June 30, 2015	$1,561,231	$(305,678)	$1,255,553

All of the Partnership's vessels as of June 30, 2015 have been provided as collateral to secure the Partnership's credit facilities.

On March 31, June 10 and June 30, 2015, the Partnership acquired the shares of the vessel owning companies of the M/T Active, the M/V Akadimos (renamed to “CMA CGM Amazon”) and the M/T Amadeus for a total consideration of $33,500, $81,500 and $33,500 respectively. The total acquisition cost of $148,500 was funded by three separate drawn downs totaling $72,389 from the Partnership's existing credit facility of $225,000 and the remaining balance of $76,111 through the Partnership's available cash. The Partnership accounted for the acquisition of the vessel owning companies of the M/T Active, the M/V Akadimos and the M/T Amadeus as acquisition of assets. Thus these vessels were recorded in the Partnership's financial statements at their respective fair values of $36,333, $91,750 and $36,333 as quoted by independent brokers. As of December 31, 2014 the Partnership had paid advances of $14,407 to CMTC for the acquisition of the shares of these vessel owning companies which were part of the advance payment of $30,224 that the Partnership made to CMTC on September 10, 2014. The difference of $15,916 between the vessels' fair values of $164,416 and the acquisition cost of $148,500 was part of the excess of $36,417 that the Partnership had recorded in its financial statements in August 2014 upon the approval of the Master Agreement and the IDR reset from the Partnership's annual meeting.

During 2015, M/T Agisilaos, M/T Avax and M/T Akeraios underwent improvements during their scheduled special and intermediate survey respectively. The costs of these improvements for the three vessels amounted to $80 and were capitalized as part of the vessels' historic cost.

Net Income Per Unit

8.	Net Income Per Unit

The general partner's common unit holders' 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 determined 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 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.

The Partnership's net income for the six month periods ended June 30, 2015 and 2014 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 Earnings Per Unit (“EPU”) as follows:


BASIC and DILUTED	For the six month periods ended June 30,
Numerators	2015		2014
Partnership's net income	$	26,260	$	19,058

Significant Accounting Policies (Abstract)
Recent Accounting Pronouncements	Recent accounting pronouncements: On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No 2014-09, Revenue From Contracts With Customers, which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This standard is effective for public entities with reporting periods beginning after December 15, 2016. Early adoption is not permitted. The Partnership is currently evaluating the impact, if any, of the adoption of this new standard. In April 2015, the FASB issued ASU 2015-03 Simplifying the Presentation of Debt Issuance Costs. To simplify presentation of debt issuance costs, the amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. This standard is effective for public entities with reporting periods beginning after December 15, 2015. Early adoption is permitted. The Partnership believes that the implementation of this standard will only affect the presentation of debt issuance costs which will be shown as a direct deduction of the related debt instead of under non-current assets in the accompanying balance sheets and has not elected the early adoption.
