COSTAMARE INC.

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2017 and 2018

(Expressed in thousands of U.S. dollars, except share and per share data, unless otherwise stated)

1. Basis of Presentation and General Information:

The accompanying consolidated financial statements include the accounts of Costamare Inc. (“Costamare”) and its wholly-owned subsidiaries (collectively, the “Company”). Costamare is organized under the laws of the Republic of the Marshall Islands.

On November 4, 2010, Costamare completed its initial public offering (“Initial Public Offering”) in the United States under the United States Securities Act of 1933, as amended (the “Securities Act”). On March 27, 2012, October 19, 2012, December 5, 2016 and May 31, 2017, the Company completed four follow-on public offerings in the United States under the Securities Act and issued 7,500,000 common shares, 7,000,000 common shares, 12,000,000 common shares and 13,500,000 common shares, respectively, par value $0.0001, at a public offering price of $14.10 per share, $14.00 per share, $6.00 per share and $7.10 per share, respectively. During 2015, the Company issued 448,800 shares to Costamare Shipping Company S.A. and 149,600 to Costamare Shipping Services Ltd. (Note 3). During 2016, the Company issued 598,400 shares, in aggregate, to Costamare Shipping Services Ltd. (Note 3). Additionally, during the year ended December 31, 2017, the Company issued 598,400 shares to Costamare Shipping Services Ltd. and another 299,200 shares during the six-month period ended June 30, 2018. On July 6, 2016, the Company implemented a dividend reinvestment plan (the “Plan”) (Note 14). As of June 30, 2018, under the Plan, the Company has issued to its common stockholders 7,984,950 shares, in aggregate. As at June 30, 2018, the aggregate issued share capital was 110,379,350 common shares. At June 30, 2018, members of the Konstantakopoulos Family owned, directly or indirectly, approximately 55.5% of the outstanding common shares, in the aggregate. Furthermore, (i) on August 7, 2013, the Company completed a public offering of 2,000,000 shares of its 7.625% Series B Cumulative Redeemable Perpetual Preferred Stock (the “Series B Preferred Stock”), par value $0.0001, at a public offering price of $25.00 per share, (ii) on January 21, 2014, the Company completed a public offering of 4,000,000 shares of its 8.50% Series C Cumulative Redeemable Perpetual Preferred Stock (the “Series C Preferred Stock”), par value $0.0001, at a public offering price of $25.00 per share, (iii) on May 13, 2015, the Company completed a public offering of 4,000,000 shares of its 8.75% Series D Cumulative Redeemable Perpetual Preferred Stock (the “Series D Preferred Stock”), par value $0.0001, at a public offering price of $25.00 per share and (iv) on January 30, 2018, the Company completed a public offering of 4,600,000 shares of its 8.875% Series E Cumulative Redeemable Perpetual Preferred Stock (the “Series E Preferred Stock”), par value $0.0001, at a public offering price of $25.00 per share.

As of December 31, 2017 and June 30, 2018, the Company owned and/or operated a fleet of 53 and 54 container vessels, respectively, with a total carrying capacity of approximately 316,307 and 315,065 twenty-foot equivalent units (“TEU”), through wholly-owned subsidiaries incorporated in the Republic of Liberia. The Company provides worldwide marine transportation services by chartering its container vessels to some of the world’s leading liner operators under long-, medium- and short-term time charters.

At June 30, 2018, Costamare had 78 wholly-owned subsidiaries, all incorporated in the Republic of Liberia, except five incorporated in the Republic of the Marshall Islands.

Revenues for the six-month period ended June 30, 2017 and 2018, derived from significant charterers individually accounting for 10% or more of revenues (in percentages of total revenues) were as follows:

	2017			2018
A		29	%		28	%
B		29	%		28	%
C		16	%		11	%
D		20	%		23	%
Total		94	%		90	%

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and applicable rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information. Accordingly, they do not include all the information and notes required by U.S. GAAP for annual 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, 2017, filed with the SEC on February 27, 2018.

COSTAMARE INC.

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2017 and 2018

(Expressed in thousands of U.S. dollars, except share and per share data, unless otherwise stated)

These unaudited interim consolidated financial statements have been prepared on the same basis as the Company's annual consolidated financial statements and, in the opinion of management, reflect all adjustments, consisting of only normal recurring adjustments, considered necessary for a fair presentation of the Company'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 and Recent Accounting Pronouncements:

A discussion of the Company’s significant accounting policies can be found in Note 2 of the Company’s Consolidated Financial Statements included in the Annual Report on Form 20-F for the year ended December 31, 2017. There have been no material changes to these policies in the six-month period ended June 30, 2018, except for as discussed below:

Adoption of new accounting standards:

Revenue from Contracts with Customers (Topic 606): On January 1, 2018, the Company adopted ASU No. 2014-09, "Revenue from Contracts with Customers" and the related amendments ("ASC 606" or "the new revenue standard") using the modified retrospective method. Under the new guidance, there is a five-step model to apply to revenue recognition. The five-steps consist of: (1) determination of whether a contract, an agreement between two or more parties that creates legally enforceable rights and obligations, exists; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when (or as) the performance obligation is satisfied. As a result of the adoption, there was no cumulative impact to the Company’s retained earnings at January 1, 2018 since the Company has chartered its vessels under time charter agreements, and in this respect, revenue is accounted for under the leases standard. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and improvements to Financial Instruments-Overall (Subtopic 825-10), which relates to technical corrections and improvements related to Update 2016-01 to increase stakeholders’ awareness of the amendments and to expedite the improvements. The amendments in this Update include items brought to the Board’s attention by stakeholders and clarify certain aspects of the guidance issued in Update 2016-01. The amendment clarifies, among others, that an entity measuring an equity security using the measurement alternative in paragraph 321-10-35-2, may change its measurement approach to a fair value method in accordance with Topic 820, Fair Value Measurement, through an irrevocable election that would apply to that security and all identical or similar investments of the same issuer. Once an entity makes this election, the entity should measure all future purchases of identical or similar investments of the same issuer using a fair value method in accordance with Topic 820. In addition the amendment clarifies that when an observable transaction occurs for a similar security, the adjustments made under the measurement alternative are intended to reflect the fair value of the security as of the date that the observable transaction for a similar security took place. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01—Financial Instruments—Overall (Subtopic 825-10), which includes the requirement for all equity investments (other than those accounted for under the equity method of accounting, those that result in consolidation of the investee or those without readily determinable fair value for which qualitative assessment does not indicate impairment) to be measured at fair value with changes in the fair value recognized through net income. The Update simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. This Update is effective for all entities for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is not permitted. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements.

(Expressed in thousands of U.S. dollars, except share and per share data, unless otherwise stated)

In August 2016, the FASB issued ASU No. 2016-15—Statement of Cash Flows (Topic 230)—Classification of Certain Cash Receipts and Cash Payments which addresses the following eight specific cash flow issues with the objective of reducing the existing diversity in practice: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of any corporate-owned life insurance policy (“COLI”) (including any bank-owned life insurance policy (“BOLI”)); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period, however early adoption is permitted. In order to conform with the current period presentation, the Company presented comparatives as required by the new ASU. During the six-month period ended June 30, 2017 and 2018, the amounts of $600 and $170, respectively, represent proceeds from settlements of insurance claims regarding hull and machinery and thus have been reclassified from Cash flows from operating activities to Cash flows from investing activities. During the six-month period ended June 30, 2017 and 2018, the amounts of $60 and nil, respectively, represent return on investment from equity method investees and thus have been reclassified from Cash flows from investing activities to Cash flows from operating activities.

In November 2016, the FASB issued ASU No. 2016-18—Statement of Cash Flows (Topic 230)—Restricted Cash, which addresses the requirement that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update apply to all entities that have restricted cash or restricted cash equivalents and are required to present a statement of cash flows under Topic 230. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period; however early adoption is permitted. Starting January 1, 2018, the Company presents cash, cash equivalents and restricted cash in the statement of cash flows as required by Topic 230, ASU 2016-18. In order to conform with the current period presentation, the Company presented comparatives as required by the new ASU. A reconciliation of the cash, cash equivalents and restricted cash is presented in the table below:

	For the six-month period ended June 30,
	2017		2018
Reconciliation of cash, cash equivalents and restricted cash
Cash and cash equivalents		195,023		124,392
Restricted cash – current portion		6,462		5,199
Restricted cash – non-current portion		36,480		30,256
Total cash, cash equivalents and restricted cash	$	237,965	$	159,847

In January 2017, the FASB issued ASU 2017-01 - Business Combinations (Topic 805) to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisition (or disposals) of assets or businesses. Under current implementation guidance, the existence of an integrated set of acquired activities (inputs and processes that generate outputs) constitutes an acquisition of business. This ASU provides a screen to determine when a set of assets and activities does not constitute a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This Update is effective for public entities with reporting periods beginning after December 15, 2017, including interim periods within those years. The amendments of this ASU should be applied prospectively on or after the effective date. Early adoption is permitted, including adoption in an interim period (i) for transactions for which the acquisition date occurs before the issuance date or effective date of the ASU, only when the transaction has not been reported in financial statements that have been issued or made available for issuance and (ii) for transactions in which a subsidiary is deconsolidated or a group of assets is derecognized that occur before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements.

In March 2018, the FASB issued ASU 2018-04 to supersede SEC paragraphs in ASC 320, Investments – Debt Securities, as a result of the issuance of SEC Staff Accounting Bulletin (SAB) 117. The adoption of this amendment (which follows the adoption of ASU 2016-01) did not have a material effect on the Company’s consolidated financial statements.

New Accounting Pronouncements - Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02—Leases (ASC 842), which requires lessees to recognize most leases on the balance sheet. This is expected to increase both reported assets and liabilities. The new lease standard does not substantially change lessor accounting. For public companies, the standard will be effective for the first interim reporting period within annual periods beginning after December 15, 2018, although early adoption is permitted. Lessees and lessors will be required to apply the new standard at the beginning of the earliest period presented in the financial statements in which they first apply the new guidance, using a modified retrospective transition method. The requirements of this standard include a significant increase in required disclosures. In addition, in July 2018, the FASB issued ASU No. 2018-11—Leases (ASC 842), which approved targeted improvements to the accounting standards and provides for (a) an optional new transition method for adoption that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption and (b) a practical expedient for lessors, under certain circumstances, to combine the lease and non-lease components of revenues for presentation purposes.  The Company intends to apply the alternative transition method and intends to elect the practical expedient for lessors for presentation purposes, upon adoption of ASC 842-Leases.The Company is analyzing the impact of the adoption of these new pronouncements on its consolidated financial statements, including assessing changes that might be necessary to information technology systems, processes and internal controls to capture new data and address changes in financial reporting.

In June 2016, the FASB issued ASU No. 2016-13—Financial Instruments—Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments. ASU 2016-13 amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. For public entities, the amendments of this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early application is permitted. Management is in the process of assessing the impact of the amendment of this Update on the Company’s consolidated financial position and performance.

In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815): Part I. Accounting for Certain Financial Instruments with Down Round Features; Part II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-controlling Interests with a Scope Exception, (ASU 2017-11). Part I of this Update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on the basis of the pricing of future equity offerings. Current accounting guidance creates cost and complexity for entities that issue financial instruments (such as warrants and convertible instruments) with down round features that require fair value measurement of the entire instrument or conversion option. Part II of this Update addresses the difficulty of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable non-controlling interests. The amendments in Part II of this Update do not have an accounting effect. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12), which amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and related disclosures.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting (Topic 718): ASU 2018-07 simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. For public business entities, the amendments in ASU 2018-07 are effective for annual periods beginning after 15 December 2018, and interim periods within those annual periods. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and related disclosures.

In July 2018, the FASB issued ASU 2018-10, Codification Improvements to (Topic 842) - Leases: ASU 2018-10 affects narrow aspects of the guidance issued in the amendments in Update 2016-02. The amendments in this Update related to transition, do not include amendments from proposed ASU, Leases (Topic 842): Targeted Improvements, specific to a new and optional transition method to adopt the new lease requirements in Update 2016-02. That additional transition method will be issued as part of a forthcoming and separate Update that will result in additional amendments to transition paragraphs included in this Update to conform with the additional transition method. Management is in the process of assessing the impact of the amendment of this Update on the Company’s consolidated financial statements.

17. Taxes:

Under the laws of the countries of incorporation for the vessel-owning companies and/or of the countries of registration of the vessels, the companies are not subject to tax on international shipping income; however, they are subject to registration and tonnage taxes, which are included in Vessel operating expenses in the accompanying consolidated statements of income.

The vessel-owning companies with vessels that have called on the United States during the relevant year of operation are obliged to file tax returns with the Internal Revenue Service. The applicable tax is 50% of 4% of U.S.-related gross transportation income unless an exemption applies. Management believes that, based on current legislation the relevant vessel-owning companies are entitled to an exemption under Section 883 of the Internal Revenue Code of 1986, as amended.

18. Derivatives:

(a) Interest rate swaps that meet the criteria for hedge accounting: The Company, according to its long-term strategic plan to maintain stability in its interest rate exposure, has decided to minimize its exposure to floating interest rates by entering into interest rate swap agreements. To this effect, the Company has entered into interest rate swap transactions with varying start and maturity dates, in order to manage its floating rate exposure.

These interest rate swaps are designed to hedge the variability of interest cash flows arising from floating rate debt, attributable to movements in three-month or six-month USD LIBOR. According to the Company’s Risk Management Accounting Policy, after putting in place the formal documentation required by ASC 815 in order to designate these swaps as hedging instruments as from their inception, these interest rate swaps qualified for hedge accounting. Accordingly, only hedge ineffectiveness amounts arising from the differences in the change in fair value of the hedging instrument and the hedged item are recognized in the Company’s earnings. Assessment and measurement of the effectiveness of these interest rate swaps are performed at each reporting period. For qualifying cash flow hedges, the fair value gain or loss associated with the effective portion of the cash flow hedge is recognized initially in “Other comprehensive income” and recognized to the consolidated statement of income in the periods when the hedged item affects profit or loss. Any ineffective portion of the gain or loss on the hedging instrument is recognized in the consolidated statement of income immediately.

19. Financial Instruments:

(a) Interest rate risk: The Company’s interest rates and loan repayment terms are described in Note 10.

(b) Concentration of credit risk: Financial instruments which potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, accounts receivable (included in current and non-current assets), equity method investments, equity securities, debt securities and derivative contracts (interest rate swaps and foreign currency contracts). The Company places its cash and cash equivalents, consisting mostly of deposits, with financial institutions of high credit ratings. The Company performs periodic evaluations of the relative credit standing of those financial institutions. The Company is exposed to credit risk in the event of non-performance by the counterparties to its derivative instruments; however, the Company limits its exposure by diversifying among counterparties with high credit ratings. The Company limits its credit risk with accounts receivable, equity method investments and equity and debt securities by performing ongoing credit evaluations of its customers’ and investees’ financial condition, receives charter hire in advance and generally does not require collateral for its accounts receivable.

(c) Fair value: The carrying amounts reflected in the accompanying consolidated balance sheet of financial assets and accounts payable approximate their respective fair values due to the short maturity of these instruments. The fair value of long-term bank loans with variable interest rates approximate the recorded values, generally due to their variable interest rates. The fair value of the interest rate swap agreements and the foreign currency agreements discussed in Note 18 above are determined through Level 2 of the fair value hierarchy as defined in FASB guidance for Fair Value Measurements and are derived principally from or corroborated by observable market data, interest rates, yield curves and other items that allow value to be determined.

The fair value of the interest rate swap agreements discussed in Note 18(a) and (b) equates to the amount that would be paid or received by the Company to cancel the agreements. As at December 31, 2017 and June 30, 2018, the fair value of these interest rate swaps in aggregate amounted to a net asset of $1,051 and $9,712, respectively.

The fair value of the forward contracts discussed in Note 18(c) determined through Level 2 of the fair value hierarchy as at December 31, 2017 and June 30, 2018, amounted to an asset of $112 and a liability of $182, respectively.

The following tables summarize the hierarchy for determining and disclosing the fair value of assets and liabilities by valuation technique on a recurring basis as of the valuation date.

There have been

except for as discussed below:

Adoption of new accounting standards:

the Company adopted ASU

No.

2014

-

09,

"Revenue from Contracts with Customers" and the related amendments ("ASC

606"

or "the new revenue standard") using the modified retrospective method. Under the new guidance, there is a

five

-step model to apply to revenue recognition. The

five

-steps consist of: (

1

) determination of whether a contract, an agreement between

two

or more parties that creates legally enforceable rights and obligations, exists; (

2

) identification of the performance obligations in the contract; (

3

) determination of the transaction price; (

4

) allocation of the transaction price to the performance obligations in the contract; and (

5

) recognition of revenue when (or as) the performance obligation is satisfied. As a result of the adoption, there was

no

cumulative impact to the Company’s retained earnings at

January 1, 2018

since the Company has chartered its vessels under time charter agreements, and in this respect, revenue is accounted for under the leases standard. The comparative information has

not

been restated and continues to be reported under the accounting standards in effect for those periods.

The amendment clarifies, among others, that an entity measuring an equity security using the measurement alternative in paragraph

may

change its measurement approach to a fair value method in accordance with Topic

820,

Fair Value Measurement, through an irrevocable election that would apply to that security and all identical or similar investments of the same issuer. Once an entity makes this election, the entity should measure all future purchases of identical or similar investments of the same issuer using a fair value method in accordance with Topic

820.

In addition the amendment clarifies that when an observable transaction occurs for a similar security, the adjustments made under the measurement alternative are intended to reflect the fair value of the security as of the date that the observable transaction for a similar security took place. The adoption of this new accounting guidance did

not

have a material effect on the Company’s consolidated financial statements.

which includes the requirement for all equity investments (other than those accounted for under the equity method of accounting, those that result in consolidation of the investee or those without readily determinable fair value for which qualitative assessment does

not

indicate impairment) to be measured at fair value with changes in the fair value recognized through net income. The Update simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. This Update is effective for all entities for fiscal years beginning after

December 15, 2017

and interim periods within those fiscal years. Early adoption is

- Business Combinations (Topic

)

to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisition (or disposals) of assets or businesses. Under current implementation guidance, the existence of an integrated set of acquired activities (inputs and processes that generate outputs) constitutes an acquisition of business. This ASU provides a screen to determine when a set of assets and activities does

not

constitute a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is

not

a business. This Update is effective for public entities with reporting periods beginning after

December 15, 2017,

including interim periods within those years. The amendments of this ASU should be applied prospectively on or after the effective date. Early adoption is permitted, including adoption in an interim period (i) for transactions for which the acquisition date occurs before the issuance date or effective date of the ASU, only when the transaction has

not

been reported in financial statements that have been issued or made available for issuance and (ii) for transactions in which a subsidiary is deconsolidated or a group of assets is derecognized that occur before the issuance date or effective date of the amendments, only when the transaction has

not

been reported in financial statements that have been issued or made available for issuance.

although early adoption is permitted. Lessees and lessors will be required to apply the new standard at the beginning of the earliest period presented in the financial statements in which they

). Part I of this Update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on the basis of the pricing of future equity offerings. Current accounting guidance creates cost and complexity for entities that issue financial instruments (such as warrants and convertible instruments) with down round features that require fair value measurement of the entire instrument or conversion option. Part II of this Update addresses the difficulty of navigating Topic

Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable non-controlling interests.

Derivative Instruments and Hedging Activities Disclosure [Text Block]

18.

Derivatives:

(a) Interest rate swaps that meet the criteria for hedge accounting:

The Company, according to its long-term strategic plan to maintain stability in its interest rate exposure, has decided to minimize its exposure to floating interest rates by entering into interest rate swap agreements. To this effect, the Company has entered into interest rate swap transactions with varying start and maturity dates, in order to manage its floating rate exposure.

These interest rate swaps are designed to hedge the variability of interest cash flows arising from floating rate debt, attributable to movements in

three

-month or

six

-month USD LIBOR. According to the Company’s Risk Management Accounting Policy, after putting in place the formal documentation required by ASC

815

in order to designate these swaps as hedging instruments as from their inception, these interest rate swaps qualified for hedge accounting. Accordingly, only hedge ineffectiveness amounts arising from the differences in the change in fair value of the hedging instrument and the hedged item are recognized in the Company’s earnings. Assessment and measurement of the effectiveness of these interest rate swaps are performed at each reporting period. For qualifying cash flow hedges, the fair value gain or loss associated with the effective portion of the cash flow hedge is recognized initially in “Other comprehensive income” and recognized to the consolidated statement of income in the periods when the hedged item affects profit or loss. Any ineffective portion of the gain or loss on the hedging instrument is recognized in the consolidated statement of income immediately.

At

December 31, 2017

and

June 30, 2018,

the Company had interest rate swap agreements with an outstanding notional amount of

$656,096

and

$328,440,

respectively. The fair value of these interest rate swaps outstanding at

December 31, 2017

and

June 30, 2018

amounted to a net asset of

$2,031

and

$9,585,

respectively, and these are included in the accompanying consolidated balance sheets. The maturity of these interest rate swaps range between

April 2020

and

May 2023.

During the

six

-month period ended

June 30, 2018,

the Company terminated

three

interest rate derivative instruments and paid the counterparties breakage costs of

$1,234

in aggregate and is separately reflected in Swap breakage costs in the accompanying consolidated statement of income for the

six

-month period ended

June 30, 2018.

The estimated net amount that is expected to be reclassified within the next

12

months from Accumulated Other Comprehensive Income / (Loss) to earnings in respect of the settlements on interest rate swaps amounts to

$2,921.

(b) Interest rate swaps that do

not

meet the criteria for hedge accounting:

the Company had interest rate swap agreements with an outstanding notional amount of

$89,752

and

$84,705,

respectively, for the purpose of managing risks associated with the variability of changing LIBOR-related interest rates. Such agreements did

not

meet hedge accounting criteria and, therefore, changes in its fair value are reflected in earnings. The fair value of these interest rate swaps at

December 31, 2017

and

June 30, 2018

was a liability of

$980

and a net asset of

$128,

respectively, and these are included in Fair value of derivatives in the accompanying consolidated balance sheets. The maturity of these interest rate swaps range between

August 2018

and

August 2020.

Financial Instruments Disclosure [Text Block]

19.

Financial Instruments:

(a) Interest rate risk:

The Company’s interest rates and loan repayment terms are described in Note

10.

(b) Concentration of credit risk:

Financial instruments which potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, accounts receivable (included in current and non-current assets), equity method investments, equity securities, debt securities and derivative contracts (interest rate swaps and foreign currency contracts). The Company places its cash and cash equivalents, consisting mostly of deposits, with financial institutions of high credit ratings. The Company performs periodic evaluations of the relative credit standing of those financial institutions. The Company is exposed to credit risk in the event of non-performance by the counterparties to its derivative instruments; however, the Company limits its exposure by diversifying among counterparties with high credit ratings. The Company limits its credit risk with accounts receivable, equity method investments and equity and debt securities by performing ongoing credit evaluations of its customers’ and investees’ financial condition, receives charter hire in advance and generally does

not

require collateral for its accounts receivable.

(c) Fair value:

The carrying amounts reflected in the accompanying consolidated balance sheet of financial assets and accounts payable approximate their respective fair values due to the short maturity of these instruments. The fair value of long-term bank loans with variable interest rates approximate the recorded values, generally due to their variable interest rates. The fair value of the interest rate swap agreements and the foreign currency agreements discussed in Note

18

above are determined through Level

2

of the fair value hierarchy as defined in FASB guidance for Fair Value Measurements and are derived principally from or corroborated by observable market data, interest rates, yield curves and other items that allow value to be determined.

The fair value of the interest rate swap agreements discussed in Note

18

(a) and (b) equates to the amount that would be paid or received by the Company to cancel the agreements. As at

December 31, 2017

and

June 30, 2018,

the fair value of these interest rate swaps in aggregate amounted to a net asset of

$1,051

and

$9,712,

respectively.

The fair value of the forward contracts discussed in Note

(c) determined through Level

"Revenue from Contracts with Customers" and the related amendments ("ASC

606"

or "the new revenue standard") using the modified retrospective method. Under the new guidance, there is a

five

-step model to apply to revenue recognition. The

five

-steps consist of: (

1

) determination of whether a contract, an agreement between

two

or more parties that creates legally enforceable rights and obligations, exists; (

2

) identification of the performance obligations in the contract; (

3

) determination of the transaction price; (

4

) allocation of the transaction price to the performance obligations in the contract; and (

5

) recognition of revenue when (or as) the performance obligation is satisfied. As a result of the adoption, there was

no

cumulative impact to the Company’s retained earnings at

January 1, 2018

since the Company has chartered its vessels under time charter agreements, and in this respect, revenue is accounted for under the leases standard. The comparative information has

not

been restated and continues to be reported under the accounting standards in effect for those periods.

may

change its measurement approach to a fair value method in accordance with Topic

Fair Value Measurement, through an irrevocable election that would apply to that security and all identical or similar investments of the same issuer. Once an entity makes this election, the entity should measure all future purchases of identical or similar investments of the same issuer using a fair value method in accordance with Topic

820.

In addition the amendment clarifies that when an observable transaction occurs for a similar security, the adjustments made under the measurement alternative are intended to reflect the fair value of the security as of the date that the observable transaction for a similar security took place. The adoption of this new accounting guidance did

not

have a material effect on the Company’s consolidated financial statements.

which includes the requirement for all equity investments (other than those accounted for under the equity method of accounting, those that result in consolidation of the investee or those without readily determinable fair value for which qualitative assessment does

not

indicate impairment) to be measured at fair value with changes in the fair value recognized through net income. The Update simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. This Update is effective for all entities for fiscal years beginning after

December 15, 2017

and interim periods within those fiscal years. Early adoption is

- Business Combinations (Topic

)

to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisition (or disposals) of assets or businesses. Under current implementation guidance, the existence of an integrated set of acquired activities (inputs and processes that generate outputs) constitutes an acquisition of business. This ASU provides a screen to determine when a set of assets and activities does

not

constitute a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is

not

a business. This Update is effective for public entities with reporting periods beginning after

December 15, 2017,

including interim periods within those years. The amendments of this ASU should be applied prospectively on or after the effective date. Early adoption is permitted, including adoption in an interim period (i) for transactions for which the acquisition date occurs before the issuance date or effective date of the ASU, only when the transaction has

not

been reported in financial statements that have been issued or made available for issuance and (ii) for transactions in which a subsidiary is deconsolidated or a group of assets is derecognized that occur before the issuance date or effective date of the amendments, only when the transaction has

). Part I of this Update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on the basis of the pricing of future equity offerings. Current accounting guidance creates cost and complexity for entities that issue financial instruments (such as warrants and convertible instruments) with down round features that require fair value measurement of the entire instrument or conversion option. Part II of this Update addresses the difficulty of navigating Topic 

480,

Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable non-controlling interests.
