Recent Developments

Acquisition of the M/T Anikitos

On May 4, 2018, we completed the acquisition from Capital Maritime of the shares of the company owning the M/T Anikitos, an eco-type MR product tanker (50,082 dwt IMO II/III chemical product tanker built in 2016, Samsung Heavy Industries (Ningbo) Co., Ltd.), for a total consideration of $31.5 million. The M/T Anikitos is currently employed by Petrobras, at a gross daily rate of $15,300, with earliest charter expiry in June 2020. The charterer has the option to extend the time charter for eighteen months (+/-30 days) at the same gross daily rate. We financed the acquisition with $15.9 million in cash and the assumption of a $15.6 million term loan (the “Anikitos tranche”) under a credit facility previously arranged by Capital Maritime with ING Bank N.V (the “2015 credit facility”). The Anikitos tranche is required to be repaid in thirteen consecutive equal quarterly installments of $0.4 million, beginning two years from the anniversary of the delivery of the M/T Anikitos, plus a balloon payment of $11.0 million, which is payable concurrently with the final quarterly instalment in June 2023. The Anikitos tranche bears interest at LIBOR plus a margin of 2.50% and is subject to ship finance covenants similar to the covenants applicable under our existing facilities.

Sale of the M/T Aristotelis and partial prepayment of our $460 million credit facility (the “2017 credit facility”)

On December 22, 2017, we entered into a memorandum of agreement for the sale of the M/T Aristotelis (51,604 dwt IMO II/III chemical product tanker built in 2013, Hyundai Mipo Dockyard Ltd., South Korea) with an unaffiliated third party for $29.4 million. Upon entering the agreement, the M/T Aristotelis met the criteria to be classified as held for sale. Under this agreement, as amended, the vessel was delivered to its buyer on April 25, 2018. On the same date, we prepaid $14.4 million under our 2017 credit facility in connection to the sale of the M/T Aristotelis.

Acquisition of the M/T Aristaios

In January 2018, we completed the acquisition from Capital Maritime of the shares of the company owning the M/T Aristaios, an eco-type crude tanker (113,689 dwt, Ice Class 1C, built in 2017, Daehan Shipbuilding Co. Ltd., South Korea), for a total consideration of $52.5 million. The M/T Aristaios is currently employed under a time charter to Tesoro at a gross daily rate of $26,400. The Tesoro charter commenced in January 2017 with duration of five years +/-45 days. We financed the acquisition with $24.2 million in cash and the assumption of a $28.3 million term loan under a credit facility previously arranged by Capital Maritime with Crédit Agricole Corporate and Investment Bank and ING Bank NV (the “Aristaios credit facility”). The Aristaios credit facility bears interest at LIBOR plus a margin of 2.85% and is payable in 12 consecutive semi-annual instalments of approximately $0.9 million beginning in July 2018, plus a balloon payment of $17.3 million payable concurrently with the last semi-annual instalment due in January 2024. The Aristaios credit facility is subject to ship finance covenants similar to the covenants applicable under our existing facilities.

Quarterly Common and Class B Unit Cash Distribution

On April 18, 2018, the Board declared a cash distribution of $0.08 per common unit for the first quarter of 2018, which was paid on May 14, 2018 to common unit holders of record as of May 2, 2018. In addition, the Board declared a cash distribution of $0.21375 per Class B Unit for the first quarter of 2018, in accordance with the Partnership’s Second Amended and Restated Partnership Agreement. This cash distribution on Class B Units was paid on May 10, 2018 to Class B Unitholders of record as of May 2, 2018.

On July 18, 2018, the Board declared a cash distribution of $0.08 per common unit for the second quarter of 2018 payable on August 14, 2018 to common unit holders of record as of August 2, 2018. In addition, the Board declared a cash distribution of $0.21375 per Class B Unit for the second quarter of 2018, in accordance with the Partnership’s Second Amended and Restated Partnership Agreement. This cash distribution on Class B Units will be paid on August 10, 2018 to Class B Unitholders of record as of August 2, 2018.

As previously announced, we intend to review our distributions from time to time in the light of a range of factors, including, among other things, our access to the capital markets, the refinancing of our external debt, the level of our capital expenditures and our ability to pursue accretive transactions. For further information on the risks affecting the level of our distributions, see “Item 3. Key Information—D. Risk Factors—Risk Related to Our Business and Operations—We cannot assure you that we will pay any distributions on our units ” in our Annual Report on Form 20-F for the year ended December 31, 2017, filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 5, 2018.

Fleet Employment

In April 2018, we reached an agreement with PIL to extend the charter of the M/V Agamemnon (108,892 dwt / 8,266 TEU, container carrier built in 2007, Daewoo Shipbuilding & Marine Engineering Co., Ltd., South Korea) for an additional eleven to thirteen months, following the expiration of the present charter, at an increased gross daily rate of $20,000. The M/V Agamemnon previously earned $8,250 gross per day under a one-year charter. The extended charter with the increased gross daily rate of $20,000 commenced in June 2018.

In April 2018, we agreed to charter the M/V Archimidis (108,892 dwt / 8,266 TEU, container carrier built in 2006, Daewoo Shipbuilding & Marine Engineering Co., Ltd., South Korea) to MSC for two years +/- 30 days at $18,000 gross per day. The charter commenced in May 2018. The M/V Archimidis previously was employed under a one-year charter with PIL at a gross daily rate of $8,250.

The M/T Avax (47,834 dwt, Ice Class 1A IMO II/III chemical product tanker, built in 2007 Hyundai Mipo Dockyard, South Korea), the M/T Axios (47,872 dwt, Ice Class 1A IMO II/III chemical product tanker, built 2007 Hyundai Mipo Dockyard, South Korea) and the M/T Assos (47,872 dwt, Ice Class 1A IMO II/III chemical product tanker, built 2006 Hyundai Mipo Dockyard, South Korea) have secured employment for two years +/- 30 days at a gross daily rate of $13,850 with Petrobras. The charterer has the option to extend the respective time charters for an additional eleven months +/-30 days at the same rate.

Furthermore, and as previously announced, the M/T Alexandros II (51,258 dwt, IMO II/III chemical/product tanker, built in 2008 STX Offshore & Shipbuilding Co., Ltd, South Korea), the M/T Aristotelis II (51,226 dwt, IMO II/III chemical/product tanker, built in 2008 STX Offshore & Shipbuilding Co., Ltd, South Korea), the M/T Aris II (51,218 dwt, IMO II/III chemical/product tanker, built in 2008 STX Offshore & Shipbuilding Co., Ltd, South Korea) and the M/T Ayrton II (51,260 dwt, IMO II/III chemical/product tanker, built in 2009 STX Offshore & Shipbuilding Co., Ltd, South Korea), have also secured employment with Petrobras for two years +/- 30 days at a gross daily rate of $14,700. The charterer has the option to extend the respective time charters for an additional eleven months +/-30 days at $14,850 per day. The charters of the M/T Aristotelis II the M/T Aris II and the M/T Ayrton II are subject to final vetting approval.

In addition the M/T Alkiviadis (36,721 dwt, Ice Class 1A IMO II/III chemical/product tanker, built in 2006 Hyundai Mipo Dockyard Company Ltd., South Korea) has been fixed by CSSA S.A., a fully owned subsidiary of Total S.A., for an additional twenty months +/- 30 days at gross daily rate of $12,500. The charter extension commenced in August 2018.

As of the date of this report, our charter coverage for the rest of 2018 and 2019 is 77% and 59%, respectively.

Factors Affecting Our Future Results of Operations

Please refer to our Annual Report on Form 20-F for the year ended December 31, 2017, filed on March 5, 2018, regarding the factors affecting our future results of operations.

5

Results of Operations

Six-Month Period Ended June 30, 2018 Compared to the Six-Month Period Ended June 30, 2017

Our results of operations for the six-month periods ended June 30, 2018 and 2017 differ primarily due to:

Total Revenues

Total revenues, consisting of time, voyage and bareboat charter revenues, amounted to $131.1 million for the six-month period ended June 30, 2018, compared to $122.3 million for the six-month period ended June 30, 2017. The increase of $8.8 million was primarily a result of the increase in the average number of vessels in our fleet and the increase in the number of voyage charters performed by our vessels during the six-month period ended June 30, 2018, partly offset by the lower average charter rates earned by certain of our vessels and the increase in off-hire days incurred by certain of our vessels that underwent their special survey during the six-month period ended June 30, 2018 compared to the corresponding period in 2017. For the six-month period ended June 30, 2018, related party revenues decreased to $12.7 million, compared to $22.2 million for the six-month period ended June 30, 2017 as the average number of vessels chartered by Capital Maritime during the six-month period ended June 30, 2018 decreased by 2.2 vessels compared to the average number of vessels chartered by Capital Maritime during the same period in 2017. Time, voyage and bareboat charter revenues are mainly comprised of the charter hires received from unaffiliated third-party charterers and Capital Maritime and are affected by the number of days our vessels operate, the average number of vessels in our fleet and the charter rates.

For the six-month period ended June 30, 2018, Petrobras, HMM and CMA CGM accounted for 18%, 17% and 16% of our total revenues, respectively. For information on the risks arising from a concentration of counterparties, see “Item 3. Key Information—D. Risk Factors—Risks Inherent in Our Operations—We currently derive all of our revenues from a limited number of charterers and the loss of any charterer or charter or vessel could result in a significant loss of revenues and cash flow ” in our Annual Report on Form 20-F for the year ended December 31, 2017.

Voyage Expenses

Total voyage expenses amounted to $18.4 million for the six-month period ended June 30, 2018, compared to $5.8 million for the six-month period ended June 30, 2017. The increase of $12.6 million was primarily attributable to the increased number of voyage charters under which certain of our vessels were employed during the six-month period ended June 30, 2018, compared to the corresponding period in 2017. Voyage expenses primarily consist of bunkers, port expenses and commissions. Voyage expenses incurred during time and bareboat charters are paid for by the charterer, except for commissions, which are paid for by us. Voyage expenses incurred during voyage charters are paid for by us.

Vessel Operating Expenses

For the six-month period ended June 30, 2018 our total vessel operating expenses amounted to $50.2 million compared to $41.7 million for the six-month period ended June 30, 2017. The $8.5 million increase in total vessel operating expenses primarily reflects the increase in the number of vessels in our fleet incurring operating expenses, following the redelivery of certain of our vessels previously employed on bareboat charters, the acquisition of M/T Aristaios, and the increase in the number of vessels passing their special survey during the six-month period ended June 30, 2018 compared to the corresponding period in 2017.

Total vessel operating expenses for the six-month period ended June 30, 2018 include expenses of $6.2 million incurred under the management agreements we have with Capital Ship Management Corp., (our “Manager”), compared to $5.7 million during the six-month period ended June 30, 2017.

6

General and Administrative Expenses

General and administrative expenses amounted to $3.2 million for the six-month period ended June 30, 2018, compared to $3.0 million for the six-month period ended June 30, 2017. General and administrative expenses include board of directors’ fees and expenses, audit and certain legal fees and other fees related to the requirements of being a publicly traded partnership.

Vessel Depreciation and Amortization

Vessel depreciation and amortization decreased to $37.0 million for the six-month period ended June 30, 2018, compared to $37.1 million for the six-month period ended June 30, 2017.

Total Other Expense, Net

Total other expense, net for the six-month period ended June 30, 2018 amounted to $13.0 million, compared to $12.7 million for the six-month period ended June 30, 2017. The increase of $0.3 million reflects higher interest costs incurred as a result of an increase in the LIBOR weighted average interest rate and the partial write-off of deferred financing costs associated with the mandatory debt prepayment in connection to the sale of M/T Aristotelis during the six-month period ended June 30, 2018, partly offset by the foreign exchange gains recognized during the same period compared to the corresponding period in 2017.

The weighted average interest rate on the loans outstanding under our credit facilities for the six-month period ended June 30, 2018 was 5.16%, compared to 4.14% for the corresponding period in 2017. See also Note 6 to our unaudited interim condensed consolidated financial statements included elsewhere herein.

Partnership’s Net Income

As a result of the factors described above, the Partnership’s net income for the six-month period ended June 30, 2018 amounted to $9.3 million, compared to $22.1 million for the six-month period ended June 30, 2017.

Liquidity and Capital Resources

As of June 30, 2018, total cash and cash equivalents amounted to $32.5 million and restricted cash (under our credit facilities) amounted to $18.5 million. As of June 30, 2018, there were no undrawn amounts under the terms of our credit facilities

Generally, our primary sources of funds have been cash from operations, bank borrowings and, depending on our access to the capital markets, securities offerings.

Depending on the prevailing market rates when our charters expire, we may not be able to re-charter our vessels at rates similar to those under their current charters or we might trade certain of our vessels in the spot market, which translate into revenues that are inherently more volatile. As a result, our future cash flows from operations may be affected. Cash flows from operations may be further affected by other factors described in our Annual Report on Form 20-F for the year ended December 31, 2017 in “Item 3. Key Information—D. Risk Factors”.

Because we distribute all of our “available cash” (a contractually defined term, generally referring to cash on hand at the end of each quarter after provision for reserves), we generally rely upon external financing sources, including bank borrowings and, depending on our access to the capital markets, securities offerings, to fund replacement, expansion and investment capital expenditures, and to refinance or repay outstanding indebtedness under our credit facilities. Since 2011, our board of directors has elected not to provision cash reserves for estimated replacement capital expenditures. Therefore, our ability to maintain and grow our asset base, including through further dropdown opportunities from Capital Maritime or acquisitions from third parties, and to pay or increase our distributions as well as to maintain a strong balance sheet depends on, among other things, our ability to obtain required financing, access financial markets and refinance part or all of our existing indebtedness on commercially acceptable terms.

In April 2016, in the face of severely depressed trading prices for master limited partnerships, including us, a significant deterioration in our cost of capital and potential loss of revenue, our board of directors took the decision to protect our liquidity position by creating a capital reserve and setting distributions at a level that our board believes to be sustainable and consistent with the proper conduct of our business. We used cash accumulated as a result of quarterly allocations to our capital reserve to partially prepay our indebtedness as part of our refinancing in October 2017. We expect to continue to reserve cash in amounts necessary to service our debt in the future, including making quarterly amortization payments. Please see “Item 8A: How We Make Cash Distributions” for further information on our cash distribution policy in our Annual Report on Form 20-F for the year ended December 31, 2017.

On September 6, 2017, we entered into the loan agreement documenting our 2017 credit facility. (See our Annual Report on Form 20-F for the year ended December 31, 2017, in “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources”).

On January 17, 2018, we partially financed the acquisition of the company owning the M/T Aristaios through the assumption of the Aristaios credit facility. The Aristaios credit facility, amounting to $28.3 million, bears interest at LIBOR plus a margin of 2.85% and is payable in 12 consecutive semi-annual instalments of approximately $0.9 million beginning in July 2018, plus a balloon payment of $17.3 million, payable concurrently with the last semi-annual instalment due in January 2024. The Aristaios credit facility is subject to ship finance covenants similar to the covenants applicable under our existing facilities.

7

On April 25, 2018, we prepaid the amount of $14.4 million under Tranche A of our 2017 credit facility in connection with the sale of M/T Aristotelis.

On May 4, 2018, we partially financed the acquisition of the company owning the M/T Anikitos through the assumption of the Anikitos tranche under the 2015 credit facility. The Anikitos tranche of $15.6 million, is required to be repaid in thirteen consecutive equal quarterly installments of $0.4 million, beginning two years from the anniversary of the delivery of the M/T Anikitos, plus a balloon payment of $11.0 million, which is payable concurrently with the final quarterly instalment in June 2023. The 2015 credit facility bears interest at LIBOR plus a margin of 2.50% and is subject to ship finance covenants similar to the covenants applicable under our existing facilities.

The table below presents our principal repayment schedule under (i) our 2017 credit facility, (ii) the Aristaios credit facility and (iii) the Amor and Anikitos tranches under our 2015 credit facility, as of June 30, 2018:

Subject to our ability to obtain required financing and access financial markets, we expect to continue to evaluate opportunities to acquire vessels and businesses. We currently have no capital commitments to purchase or build additional vessels. For the twelve-month period ending June 30, 2019, we anticipate that three of our vessels will undergo special survey.

Total partners’ capital as of June 30, 2018 amounted to $916.9 million compared to $933.4 million as of December 31, 2017, corresponding to a decrease of $16.5 million. The decrease primarily reflects $26.3 million of distributions declared and paid during the six-month period ended June 30, 2018 partially offset by net income of $9.3 million and equity compensation expense of $0.5 million.

As of June 30, 2018, we had negative working capital, which was driven principally by repayments of our credit facilities over the next 12 months, as well as other factors, such as deferred revenues.

Subject to shipping and charter and financial market developments, we believe that our working capital will be sufficient to meet our existing liquidity needs for at least the next 12 months.

Cash Flows

The following table summarizes our cash and cash equivalents provided by / (used in) operating, investing and financing activities for the periods, presented in millions:

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $48.0 million for the six-month period ended June 30, 2018 compared to $62.3 million for the six-month period ended June 30, 2017. The decrease of $14.3 million was mainly attributable to (a) the decrease of $11.9 million in cash from operations, which was attributable to, among other factors, lower time charter rates affecting our revenues and an increase in our total expenses, including vessel voyage and operating expenses and (b) the negative effect of the changes in our operating assets and liabilities amounting to $2.8 million, which were partially offset by a decrease of $0.4 million in dry-docking costs. Changes in our operating assets and

8

liabilities were driven mainly by an increase in our inventories and trade receivables and a decrease in deferred revenue, in each case mainly attributable to the increase in the number of voyage charters performed by our vessels, partly offset by a reduction in the amounts we reimbursed to our Manager for expenses paid on our behalf and by the increase in trade accounts payable and accrued liabilities during the six-month period ended June 30, 2018, compared to the six-month period ended June 30, 2017.

Net Cash Used in Investing Activities

Net cash used in investing activities refers primarily to cash used for vessel acquisitions and improvements partly offset by proceeds from the sale of vessels. Net cash used in investing activities for the six-month period ended June 30, 2018 amounted to $11.1 million compared to $1.4 million during the six-month period ended June 30, 2017. The increase of $9.7 million in net cash flows used in investing activities during the six-month period ended June 30, 2018, was primarily attributable to cash used for the acquisition of the companies owning the M/T Anikitos and the M/T Aristaios, partially offset by the proceeds from the sale of the M/T Aristotelis. During the six-month period ended June 30, 2017, we did not acquire or dispose of any vessels. Cash consideration paid for vessel improvements for the six-month period ended June 30, 2018 amounted to $0.5 million compared to $1.4 million during the six-month period ended June 30, 2017.

Net Cash Used in Financing Activities

Net cash used in financing activities for the six-month period ended June 30, 2018, was $67.2 million compared to $29.3 million for the six-month period ended June 30, 2017. The increase of $37.9 million in net cash used in financing activities was mainly attributable to (a) the increase in amortization payments of long-term debt by $32.1 million following the refinancing of approximately all of our credit facilities outstanding in October 2017, resulting in an increase in long term debt principal amortization under our new 2017 credit facility and the mandatory prepayment under the same facility following the disposal of the M/T Aristotelis; (b) the decrease by $5.0 million in net proceeds from the issuance of common units (as we did not issue common units under our shelf registration in the six-month period ended June 30, 2018) and (c) the increase by $0.7 million in distributions to our unitholders during the six-month period ended June 30, 2018 compared to the corresponding period in 2017.

Borrowings

Our long-term borrowings are reflected in our balance sheet as “Long-term debt, net” and in current liabilities as “Current portion of long-term debt, net”.

As of June 30, 2018, total borrowings were $478.9 million, consisting of: (i) $419.2 outstanding under our 2017 credit facility; (ii) $15.8 million outstanding under the Amor tranche of the 2015 credit facility; (iii) $15.6 million outstanding under the Anikitos tranche of the 2015 credit facility and (iv) $28.3 million outstanding under Aristaios credit facility.

As of December 31, 2017, our total borrowings were $475.8 million, consisting of (i) $460.0 million principal amount outstanding under our 2017 credit facility and (ii) $15.8 million principal amount outstanding under the Amor tranche of the 2015 credit facility.

Credit Facilities

For information relating to our credit facilities, please refer to Note 7 of our audited Consolidated Financial Statements included in the Annual Report on Form 20-F for the year ended December 31, 2017, Note 6 to our unaudited interim condensed consolidated financial statements included elsewhere herein and the description above in “Liquidity and Capital Resources”.

As of June 30, 2018 and December 31, 2017, we were in compliance with all financial debt covenants. Our ability to comply with the covenants and restrictions contained in our credit facilities and any other debt instruments we may issue or enter into in the future may be affected by events beyond our control, including prevailing economic, financial and industry conditions, such as interest rate developments, changes in the funding costs offered by our banks and changes in asset valuations. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired. If we are in breach of any of the restrictions, covenants, ratios or tests in our credit facilities, we are unlikely to be able to make any distributions to our unitholders, a significant portion of our obligations may become immediately due and payable and our lenders’ commitment to make further loans to us, if any, may terminate. We may not have, or be able to obtain, sufficient funds to make these accelerated payments. In addition, obligations under our credit facilities are secured by our vessels, and if we are unable to repay debt under the credit facilities, the lenders could seek to foreclose on those assets.

Any contemplated vessel acquisitions will have to be at levels that do not impair the required ratios, see “Item 5.B. Liquidity and Capital Resources—Borrowings—Our Credit Facilities” in our Annual Report on Form 20-F for the year ended December 31, 2017. The global economic downturn that has occurred in the last several years has had an adverse effect on vessel values, and economic conditions remain fragile with significant uncertainty surrounding levels of recovery and long-term economic growth effects. If the estimated asset values of vessels in our fleet decrease, we may be obligated to prepay part of our outstanding debt in order to remain in compliance with the relevant covenants in our credit facilities. A decline in the market value of our vessels could also affect our ability to refinance our credit facilities and/or limit our ability to obtain additional financing. A decrease of 10% in the aggregate fair market values of our vessels would not cause any violation of the total indebtedness to aggregate market value covenant contained in our credit facilities.

Off-Balance Sheet Arrangements

As of June 30, 2018, we have not entered into any off-balance sheet arrangements.

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-seven high specification vessels consists of four suezmax crude oil tankers, twenty-one modern medium range tankers all of which are classed as IMO II/III vessels, ten post panamax container carrier vessels, one aframax crude-oil tanker 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 unaudited condensed consolidated financial statements and the accompanying notes should be read in conjunction with the Partnership’s consolidated financial statements for the year ended December 31, 2017, included in the Partnership’s Annual Report on Form 20-F for the fiscal year ended December 31, 2017, filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 5, 2018.

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, 2018 are not necessarily indicative of the results that might be expected for the fiscal year ending December 31, 2018.

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, 2017 (the “Consolidated Financial Statements for the year ended December 31, 2017”).

3. Transactions with related parties

The Partnership and its subsidiaries have related-party transactions including vessel acquisitions (Note 4) with Capital Maritime & Trading Corp. (“CMTC”) which is a related party unit holder. The Partnership and its subsidiaries have also related party transactions with Capital Ship Management Corp. (the “Manager” or “CSM”) arising from certain terms of the following three different types of management agreements.

The Manager has the right to terminate the Crude management agreement and, under certain circumstances, could receive substantial sums in connection with such termination. In March 2018 this termination fee was adjusted to $10,347 from $10,124.

All the above three agreements constitute the “Management Agreements” and the related management fees are included in “Vessel operating expenses – related party” in the accompanying unaudited condensed consolidated statements of comprehensive income.

3. Transactions with related parties – continued

On April 4, 2007, the Partnership entered into an administrative services agreement with the Manager, pursuant to which the Manager has agreed to provide certain administrative management services to the Partnership such as accounting, auditing, legal, insurance, IT, clerical, and other administrative services. Also the Partnership reimburses the Manager and its general partner, Capital GP L.L.C. (the “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. In January 2016, the Partnership amended the executive services agreement with CGP according to which CGP also provides certain executive officers services for the management of the Partnership’s business as well as investor relation and corporate support services to the Partnership. For the six-month periods ended June 30, 2018 and 2017 such fees amounted to $844, for each period, and are included in “General and administrative expenses” in the accompanying unaudited condensed consolidated statements of comprehensive income.

Balances and transactions with related parties consisted of the following:

4. Fixed assets and assets held for sale

An analysis of vessels, net is as follows:

All of the Partnership’s vessels as of June 30, 2018 have been provided as collateral to secure the Partnership’s credit facilities.

On May 4, 2018, pursuant to the agreement the Partnership had entered into in January 2018 and the Share Purchase Agreement (“SPA”) entered into with CMTC on May 4, 2018, acquired the shares of the company owning the M/T Anikitos an eco-type medium range product tanker (50,082 dwt IMO II/III Chemical Product Tanker built in 2016, Samsung Heavy Industries (Ningbo) Co., Ltd.) for a total consideration of $31,500, comprising $15,875 in cash and the assumption of the then outstanding balance of $15,625 (the “Anikitos Tranche”) of a credit facility (“2015 credit facility”) previously arranged by CMTC with ING Bank NV (Note 6). The Partnership also assumed CMTC’s guarantee with respect to this loan. The Partnership accounted for this acquisition as acquisition of an asset as the fair values of the vessel and the time charter attached, are concentrated in a single identifiable asset, the M/T Anikitos. The Partnership considered whether any value should be assigned to the attached charter party agreement acquired and concluded that the contracted daily charter rate was above the market rates on the acquisition date and therefore the total consideration was allocated to the vessel cost and the above market acquired charter. The Partnership allocated the cost of the vessel and the time charter acquired on the basis of their relative fair values. Thus the vessel was recorded in the Partnership’s financial statements at a value of $31,004 and the above market acquired charter at a value of $496 (Note 5).

4. Fixed assets and assets held for sale – Continued

(a) Vessels, net – Continued

On January 17, 2018, the Partnership entered into an SPA with CMTC for the purchase of the shares of the company owning the M/T Aristaios, a 113,689 DWT crude oil tanker, for a total consideration of $52,500 comprising $24,167 in cash and the assumption of the then outstanding balance of $28,333 of Advance A of a credit facility (the “Aristaios credit facility”) previously arranged by CMTC with Credit Agricole Corporate and Investment Bank and ING Bank NV (Note 6). The Partnership also assumed CMTC’s guarantee with respect to this loan. The Partnership accounted for this acquisition as acquisition of an asset as the fair values of the vessel and the time charter attached, are concentrated in a single identifiable asset, the M/T Aristaios. The Partnership considered whether any value should be assigned to the attached charter party agreement acquired and concluded that the contracted daily charter rate was above the market rates on the acquisition date and therefore the total consideration was allocated to the vessel cost and the above market acquired charter. The Partnership allocated the cost of the vessel and the time charter acquired on the basis of their relative fair values. Thus the vessel was recorded in the Partnership’s financial statements at a value of $42,955 and the above market acquired charter at a value of $9,545 (Note 5).

(b) Improvements

During the six-month period ended June 30, 2018 and 2017, certain of the Partnership’s vessels underwent improvements. The costs of these improvements amounted to $954 and $944 respectively and were capitalized as part of the vessels’ cost.

(c) Assets held for sale

An analysis of assets held for sale is as follows:

On December 22, 2017 the Partnership entered into a Memorandum of Agreement with an unrelated party for the disposal of the M/T Aristotelis at a price of $29,400. Upon entering the agreement the Partnership considered that M/T Aristotelis met the criteria to be classified as held for sale and measured the vessel at the lower of its carrying amount and fair value less the cost associated with the sale. As of January 1, 2018 the amount of $29,027 represented the vessel’s fair value less cost to sell of $28,862 and inventories of $165. Under this agreement, as amended, the vessel was delivered to its Buyer on April 25, 2018.

5. Above market acquired charters

On May 4, 2018 the Partnership acquired the shares of the company owning the M/T Anikitos from CMTC including a time charter attached to the vessel with a time charter daily rate exceeding the market rate for equivalent time charters prevailing at the time of acquisition. The value allocated to the above market acquired time charter of $496 was determined on the basis of the relative fair values of the assets in the asset group acquired. The fair value of the time charter representing the difference between the time charter rate at which the vessel was fixed and the market rate for comparable charters, was determined by independent appraisers on the acquisition date and was recorded as an asset in the unaudited condensed consolidated balance sheet as of the acquisition date under “above market acquired charters” (Note 4).

On January 17, 2018 the Partnership acquired the shares of the company owning the M/T Aristaios from CMTC including a time charter attached to the vessel with a time charter daily rate exceeding the market rate for equivalent time charters prevailing at the time of acquisition. The value allocated to the above market acquired time charter of $9,545 was determined on the basis of the relative fair values of the assets in the asset group acquired. The fair value of the time charter representing the difference between the time charter rate at which the vessel was fixed and the market rate for comparable charters, was determined by independent appraisers on the acquisition date and was recorded as an asset in the unaudited condensed consolidated balance sheet as of the acquisition date under “above market acquired charters” (Note 4).

Above market charters acquired are amortized using the straight line method as a reduction to revenues over the remaining term of the charters. For the six-month periods ended June 30, 2018 and 2017, revenues were reduced by $8,278 and $7,744 as a result of the amortization of the above market acquired charters, respectively.

5. Above market acquired charters – Continued

An analysis of above market acquired charters is as follows:

As of June 30, 2018 the remaining carrying amount of unamortized above market acquired time charters was $76,798 and will be amortized in future years as follows:

6. Long-Term Debt

As of June 30, 2018 and December 31, 2017 the Partnership’s long-term debt consisted of the following:

Details of the Partnership’s credit facilities are discussed in Note 7 of the Partnership’s Consolidated Financial Statements for the year ended December 31, 2017.

On May 4, 2018, upon the completion of the acquisition of the shares of the company owning the M/T Anikitos (Note 4), the Partnership assumed CMTC’s guarantee with respect to the outstanding balance of $15,625 under the term loan that was entered into on November 19, 2015 with ING Bank N.V. The term loan is required to be repaid in thirteen consecutive equal quarterly installments of $355, beginning in May 2020, plus a balloon payment of $11,010 payable together with the final quarterly instalment in June 2023. The term loan bears interest at LIBOR plus a margin of 2.50%.

On January 17, 2018, upon the completion of the acquisition of the shares of the company owning the M/T Aristaios (Note 4), the Partnership assumed CMTC’s guarantee with respect to the outstanding balance of $28,333 under the term loan that was entered into on January 2, 2017 with Credit Agricole Corporate and Investment Bank and ING Bank NV. The term loan is required to be repaid in twelve consecutive equal semi-annual installments of $917, beginning in July 2018, plus a balloon payment of $17,333 payable together with the final semi-annual installment due in January 2024. The term loan bears interest at LIBOR plus a margin of 2.85%.

6. Long-Term Debt – Continued

During the six-month period ended June 30, 2018 the Partnership repaid the amount of $26,416 in line with the amortization schedule of its 2017 credit facility and prepaid the amount of $14,383 in connection with the sale of the M/T Aristotelis under the same facility.

As of June 30, 2018 and December 31, 2017 the Partnership was in compliance with all financial debt covenants.

For the six-month periods ended June 30, 2018 and 2017 interest expense amounted to $12,518 and $12,481, respectively and the weighted average interest rate of the Partnership’s loan facilities was 5.16% and 4.14% respectively.

7. Financial Instruments

The Partnership follows the accounting guidance for financial instruments that establishes a framework for measuring fair value under 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 a 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.

(a) Fair value of financial instruments

The carrying value of cash and cash equivalents and restricted cash, which are considered Level 1 items as they represent liquid assets with short-term maturities, trade receivables, due to related parties, trade accounts payable and accrued liabilities approximates their fair value. The fair values of long-term variable rate bank loans approximate the recorded values, due to their variable interest being the LIBOR and due to the fact the lenders have the ability to pass on their funding cost to the Partnership under certain circumstances, which reflects their current assessed risk. The Partnership believes that the terms of its loans are similar to those that could be procured as of June 30, 2018. LIBOR rates are observable at commonly quoted intervals for the full terms of the loans and hence bank loans are considered Level 2 items in accordance with the fair value hierarchy.

(b) Concentration of credit risk

Financial instruments which potentially subject the Partnership to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable. The Partnership places its cash and cash equivalents, consisting mostly of deposits with creditworthy financial institutions rated by qualified rating agencies. A limited number of financial institutions hold the Partnership’s cash. Most of the Partnership’s revenues were derived from a few charterers. For the six month periods ended June 30, 2018 and 2017 there were three and four customers respectively, that each accounted for more than 10% of the Partnership’s revenues for each period. The Partnership does not obtain rights of collateral from its charterers to reduce its credit risk.

8. Partners’ Capital

As of June 30, 2018 and December 31, 2017 the Partnership’s partners’ capital was comprised of the following units:

8. Partners’ Capital – continued

During the six-month period ended June 30, 2017, the Partnership issued 1,536,403 new common units under its At-The-Market offering (the “ATM offering”) and equity distribution agreement the Partnership had entered into with UBS Securities LLC in September 2016. This issuance resulted in net proceeds of $5,120 after the payment of commission to the sales agent but before offering expenses. During the six-month period ended June 30, 2018 the Partnership did not issue any new common units under its ATM offering.

Details of the Partnership’s Partner’s Capital are discussed in Note 12 of the Partnership’s Consolidated Financial Statements for the year ended December 31, 2017.

During the six-month periods ended June 30, 2018 and 2017, the Partnership declared and paid the following distributions to its common and preferred unit holders:

9. Omnibus Incentive Compensation Plan

As of June 30, 2018 the unvested units accrued $514 of distributions.

The following table contains details of the plan:

For the six-month periods ended June 30, 2018 and 2017 the equity compensation expense that has been charged in the unaudited condensed consolidated statements of comprehensive income was $217 for each period for the employee awards and $249 and $361 for the non-employee awards, respectively. This expense has been included in “General and administrative expenses” in the unaudited condensed consolidated statements of comprehensive income.

As of June 30, 2018 the total unrecognized compensation cost related to non-vested awards is $462 and is expected to be recognized over a weighted average period of 0.5 year. The Partnership uses the straight-line method to recognize the cost of the awards.

10. Net Income Per Unit

The general partner’s and 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 Limited Partnership Agreement (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 and 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.

The Partnership 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 excluded the effect of the 12,983,333 Class B Convertible Preferred Units in calculating dilutive Earnings Per Unit (“EPU”) as of June 30, 2018 and 2017 as they were anti-dilutive.

As of June 30, 2018 and 2017 the Partnership excluded the effect of 545,002 and 679,168 non-vested unit awards in calculating dilutive EPU for its common unitholders respectively, as they were anti-dilutive. The non-vested units are participating securities because they receive distributions from the Partnership and these distributions do not have to be returned to the Partnership if the non-vested units are forfeited by the grantee.

The Partnership’s net income for the six-month periods ended June 30, 2018 and 2017 did not exceed the First Target Distribution Level of $0.2425 per unit per quarter, as such term is defined in the Partnership Agreement, 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:

11. 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.

(a) Lease Commitments

Future minimum rental receipts, excluding any profit share revenue that may arise, based on non-cancellable long-term time and bareboat charter contracts, as of June 30, 2018 are:
