Basis of Presentation and General Information [Abstract]
Basis of Presentation and General Information	1 . Basis of Presentation and General Information The accompanying consolidated financial statements include the ac counts of Diana Shipping Inc. ( or “DSI” ) and its wholly-owned and beneficially-owned subsidiaries (collectively, the “Company”). DSI was formed on March 8, 1999 as Diana Shipping Investment Corp. under the laws of the Republic of Liberia. In February 2005, the Company's articles of incorporation were amended. Under the amended articles of incorporation, the Company was renamed Diana Shipping Inc. and was re - domiciled from the Republic of Liberia to the Republic of the Marshall Islands. The Company is engaged in the ocean transportation of dry bulk cargoes worldwide mainly through the ownership of dry bulk carrier vessels. The Company also operates the majority of its own fleet through Diana Shipping Services S.A. ( or “DSS”) , a wholly - owned subsidiary and a limited number of vessels through a 50% owned joint venture (Notes 3 and 4 ) . The consolidated balance sheet as of December 31, 2015 has been derived from the audited consolidated financial statements at that date, as adjusted to conform to current period presentation for compensating cash balance, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Diana Shipping Services S.A. , or DSS , provides the Company and its vessels with management services since November 12, 2004, pursuant to management agreements and since October 1, 201 3 administrative services with regards to services related to DSI's operations and its subsidiaries . Such costs are eliminated in consolidation. As at December 31, 2016, DSS does not provide management services to seven vessels in the Company's fleet whose management has been transferred progressively since August 2015 to Diana Wilhelmsen Management Limited (Notes 3 (b) and 4 (d) ). During 2016 , 2015 and 2014 c harterers that individually accounted for 10% or more of the Company's time charter revenues were as follows: Charterer 2016 2015 2014 A 19% 24% 10% B 15% C 10% 20% D 10% 18% E 12% 12% F 10% 15%

Significant Accounting Policies and Recent Accounting Pronouncements [Abstract]
Significant Accounting Policies	Principles of Consolidation : The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles , and include the accounts of Diana Shipping Inc. an d its wholly-owned subsidiaries . All intercompany balances and transactions have been eliminated upon consolidation. Use of Estimates: The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Other Comprehensive Income / ( loss ) : The Company separate ly present s certain transactions, which are recorded directly as components of stockholders' equity . Other Comprehensive Income / (Loss) is presented in a separate statement. Foreign Currency Translation: The functional currency of the Company is the U.S. d ollar because the Company's vessels operate in international shipping markets, and therefore primarily transact business in U.S. d ollars. The Company's account ing records are maintained in U.S. d ollars. Transactions involving other currencies during the year are converted into U.S. d ollars using the exchange rates in effect at the time of the transactions. At the balance sheet dates, monetary assets and liabilities which are denominated in other currencies are translated into U.S. d ollars at the year-end exchange rates. Resulting gains or losses are reflected separately in the accompanying consolidated statements of operations . Cash and Cash Equivalents: The Company considers highly liquid investments such as time deposits, certificates of deposit and their equivalents with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents may also include compensating cash balances kept against the Company's loan facilities that are not deemed to be sufficiently material to require segregation on the balance sheet. As of December 31, 2016 and 2015, such balances are separately presented as “Compensating cash balance” and consist of minimum cash deposits required to be maintained at all times under the Company's loan facilities (Note 8). Accounts Receivable, Trade: The amount shown as accounts receivable, trade , at each balance sheet date, includes receivables from charterers for hire , ballast bonus billings, if any, hold cleanings and extra voyage insurance, net of any provision for doubtful accounts. At each balance sheet date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate provision for doubtful accounts. No provision for doubtful accounts was established as of December 31, 2016 and 2015 . Loan Receivable from Related Parties : The amounts shown as Due from related parties, current and non-current, in the consolidated balance sheet as at December 31, 2016 and 2015 , (Note 4 (b)) represent amounts receivable from Diana Containerships Inc. with respect to a loan agreement with a wholly owned subsidiary of Diana Containerships Inc., net of any provision for credit losses. Interest income and fees, deriving from the agreement are recorded in the accounts as incurred. At each balance sheet date, amounts due under the aforementioned loan agreement are assessed for purposes of determining the appropriate provision for credit losses. As at December 31, 2016 and 2015 , the Company assess ed the ability of Diana Containerships to meet its obligations under the loan agreement by taking into consideration existing economic conditions, the current financial condition of Diana Containerships Inc. historical losses, and other risks/factors that may affect its future financial condition and its ability to meet its obligations . As a result of this assessment, the Company did not record any provision for credit losses, as it determined that Diana Containerships will be able to meet its obligations under the loan in the near future. Inventories : Inventories consist of lubricants and victualling which are stated at the lower of cost or market. Cost is determined by the first in, first out method. Inventories may also consist of bunkers when on the balance sheet date a vessel remains idle. Bunkers are also stated at the lower of cost or market and cost is determined by the first in, first out method. Vessel Cost: Vessels are stated at cost which consists of the contract price and any material expenses incurred upon acquisition or during construction . E xpenditures for conversions and major improvements are also capitalized when they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels; otherwise these amounts are charged to expense as incurred. Interest cost incurred during the assets' construction periods that theoretically could have been avoided if expenditure for the assets had not been made is also capitalized. The capitalization rate, applied on accumulated expenditures for the vessel, is based on interest rates applicable to outstanding borrowings of the period. Property and equipment: The Company owns t he land and building where its offices are located. Land is presented in its fair value on the date of acquisition and it is not subject to depreciation . The building has an estimated useful life of 55 years with no residual value. Depreciation is calculated on a straight-line basis. Equipment consists of office furniture and equipment, computer software and hardware and vehicles which consist of motor scooters and a car . The useful life of the car is 10 year s , of the office furniture, equipment and the scooters is 5 years; and of the computer software and hardware is 3 years. Depreciation is calculated on a straight-line basis. Impairment of Long-Lived Assets: L ong-lived assets (vessels, land, and building) and certain identifiable intangibles held and used by an entity are reviewed for impairment whenever events or changes in circumstances (such as market conditions, obsolesce or damage to the asset , potential sales and other business plans ) indicate that the carrying amount of the assets may not be recoverable. When the estimate of undiscounted projected net operating cash flows, excluding interest charges, expected to be generated by the use of the asset over its remaining useful life and its eventual disposition is less than its carrying amount, the Company should evaluate the asset for an impairment loss. Measurement of the impairment loss is based on the fair value of the asset. The Company determines the fair value of its assets based on management estimates and assumptions and by making use of available market data and taking into consideration third party valuations. With respect to the vessels, the Company determines undiscounted projected net operating cash flows for each vessel by considering the historical and estimated vessels' performance and utilization, assuming ( i ) future revenues calculated for the fixed days, using the fixed charter rate of each vessel from existing time charters and for the unfixed days, the most recent 10 year average of historical 1 year time charter rates available for each type of vessel over the remaining estimated life of each vessel, net of brokerage commissions. Historical ten-year blended average one-year time charter rates are in line with the Company's overall chartering strategy, they reflect the full operating history of vessels of the same type and particulars with the Company's operating fleet and they cover at least a full business cycle; (ii) expected outflows for scheduled vessels' maintenance; (iii) vessel operating expenses increasing annually by an annual inflation rate of 3%, which approximates current projections for global inflation rate; (iv) effective fleet utilization of 98% taking into account the period each vessel is expected to remain off hire for scheduled maintenance (dry docking and special surveys) and 1% off hire days (other than for dry docking and special surveys) each year, assumptions in line with the Company's historical performance and its expectations for future fleet utilization under its current fleet deployment strategy. The Company concluded based on this exercise that step two of the impairment analysis was not required and has not identified any facts or circumstances that would require the write down of vessel values as at December 31, 2016 or in the near future and n o impairment loss has been identified or recorded for 2016 , 2015 and 2014 . With respect to the land and building , t he Company determines undiscounted projected net operating cash flows by considering an estimated monthly rent the Company would have to pay in order to lease a similar property , during the useful life of the building . As at December 31, 2016, 2015 and 2014, no impairment loss was identified or recorded and the Company has not identified any other facts or circumstances that would require the write down of the value of its land or building in the near future. Vessel Depreciation : Depreciation is computed using the straight-line method over the estimated useful life of the vessels, after considering the estimated salvage (scrap) value. Each vessel's salvage value is equal to the product of its lightweight tonnage and estimated scrap rate. Management estimates the useful life of the Company's vessels to be 25 years from the date of initial delivery from the shipyard. Second hand vessels are depreciated from the date of their acquisition through their remaining estimated useful life. When regulations place limitations over the ability of a vessel to trade on a worldwide basis, its remaining useful life is adjusted at the date such regulations are adopted . Accounting for Dry-Docking Costs : The Company follows the deferral method of accounting for dry-docking costs whereby actual costs incurred are deferred and are amortized on a straight-line basis over the period through the date the next dry-docking is scheduled to become due. Unamortized dry-docking costs of vessels that are sold are written off and included in the calculation of the resulting gain or loss in the year of the vessel's sale . Financing Costs : Fees paid to lenders for obtaining new loans or refinancing existing ones are deferred and recorded as a contra to debt. Other fees paid for obtaining loan facilities not used at the balance sheet date are capitalized as deferred financing costs. Fees relating to drawn loan facilities are amortized to interest and finance costs over the life of the related debt using the effective interest method and fees incurred for loan facilities not used at the balance sheet date are amortized using the straight line method according to their availability terms. Unamortized fees relating to loans repaid or refinanced as debt extinguishment are expensed as interest and finance costs in the period the repayment or extinguishment is made. Loan commitment fees are charged to expense in the period incurred, unless they relate to loans obtained to finance vessels under construction, in which case they are capitalized to the vessels' cost. Concentration of Credit Risk: Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist principally of cash , trade accounts receivable and the loan receivable from a related party . The Company places its temporary cash investments, consisting mostly of deposits, with various qualified financial institutions and performs periodic evaluations of the relative credit standing of those financial institutions that are considered in the Company's investment strategy. The Company limits its credit risk with accounts receivable by performing ongoing credit evaluations of its customers' financial condition and generally does not require collate ral for its accounts receivable and does not have any agreements to mitigate credit risk. The Company limits its credit risk with the loan receivable by performing ongoing credit evaluations of Diana Containerships' financial condition. The loan agreement is guaranteed by Diana Containerships but does not have any collateral and the Company has not entered into any agreement to mitigate credit risk. Accounting for Revenues and Expenses: Revenues are generated from time charter agreements and are usually paid fifteen days in advance. Time charter agreements with the same charterer are accounted for as separate agreements according to the terms and conditions of each agreement. Time charter revenues are recorded over the term of the charter as service is provided. Income representing ballast bonus payments by the charterer to the vessel owner is recognized in the period earned. Revenues from time charter agreements providing for varying annual rates over their term are accounted for on a straight line basis. Compensation due to earlier redelivery tha n the minimum period agreed in the charter party is recognized in the period earned. Deferred revenue includes cash received prior to the balance sheet date for which all criteria to recogni ze as revenue have not been met. D eferred revenue may also include deferred revenue resulting from charter agreements providing for varying annual rates, which are accounted for on a straight line basis , or the unamortized balance of the liability associated with the acquisition of second-hand vessels with time charters attached which were acquired at values below fair market value at the date the acquisition agreement is consummated. Voyage expenses, primarily consisting of commissions, port, canal and bunker expenses that are unique to a particular charter, are paid for by the charterer under time charter arrangements, except for commissions, which are always paid for by the Company, regardless of charter type. All voyage and vessel operating expenses are expensed as incurred, except for commissions. Commissions are deferred over the related voyage charter period to the extent revenue has been deferred since commissions are due as the Company's revenues are earned. Repairs and Maintenance: All repair and maintenance expenses including underwater inspection expenses are expensed in the year incurred. Such costs are included in vessel operating expenses in the accompanying consolidated statements of operations . Earnings / (loss) per Common Share: Basic earnings / (loss) per common share are computed by dividing net income / (loss) available to common stockholders by the weighted average number of common shares outstanding during the year. Diluted earnings per common share, reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised. Segmental Reporting: The Company has determined that it operates under one reportable segment, relating to its operations of the dry-bulk vessels. The Company reports financial information and evaluates the operations of the segment by charter revenues and not by the length of ship employment for its customers, i.e. spot or time charters. The Company does not use discrete financial information to evaluate the operating results for each such type of charter. Although revenue can be identified for these types of charters, management cannot and does not identify expenses, profitability or other financial information for these charters. As a result, management, including the chief operating decision maker, reviews operating results solely by revenue per day and operating results of the fleet. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable. Fair Value Measurements : T he Company classifies and discloses its assets and liabilities carried at the fair value in one of the following categories: Level 1: Quoted market prices in active markets for identical assets or liabilities; Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data; Level 3: Unobservable inputs that are not corroborated by market data. Share Based Payment s : T he Company measure s the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost is recognized over the period during which an employee is required to provide service in exchange for the award—the requisite service period (usually the vesting period). No compensation cost is recognized for equity instruments for which employees do not render the requisite service. Employee share purchase plans will not result in recognition of compensation cost if certain conditions are met. The Company initially measures the cost of employee services received in exchange for an award or liability instrument based on its current fair value; the fair value of that award or liability instrument is re - measured subsequently at each reporting date through the settlement date. Changes in fair value during the requisite service period are recognized as compensation cost over that period with the exception of awards granted in the form of restricted shares which are measured at their grant date fair value and are not subsequently re - measured. The grant-date fair value of employee share options and similar instruments are estimated using option-pricing models adjusted for the unique characteristics of those instruments (unless observable market prices for the same or similar instruments are available). If an equity award is modified after the grant date, incremental compensation cost will be recognized in an amount equal to the excess of the fair value of the modified award over the fair value of the original award immed iately before the modification . Derivatives: The Company is exposed to interest rate fluctuations associated with its variable rate borrowings and its objective is to manage the impact of such fluctuations on earnings and cash flows of its borrowings. In this respect, in May 2009, the Company entered into a five-year zero cost collar agreement, novated in March 2012, and terminated in May 2014, to manage its exposure to interest rate changes related to its borrowings. The collar agreement was considered as an economic hedge agreement as it did not meet the criteria of hedge accounting; therefore, the change s in its fair value were recognized in earnings (Note 14 ). Equity method investments: Investments in common stock in entities over which the Company exercises significant influence, but does not exercise control are accounted for by the equity method of accounting. Under this method , the Company records such an investment at cost and adjusts the carrying amount for its share of the earnings or losses of the entity subsequent to the date of investment and reports the recognized earnings or losses in income. Dividends received , if any, reduce the carrying amount of the investment. When the Company's share of losses in an entity accounted for by the equity method equals or exceeds its interest in the entity, the Company does not recognize further losses, unless the Company has made advances, incurred obligations and made payments on behalf of the entity. The Company also evaluates whether a loss in value of an investment that is other than a temporary decline should be recognized. Evidence of a loss in value might include absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity that would justify the carrying amount of the investment. In 2016 , the Company assessed the financial condition of Diana Containerships Inc. , the market conditions that could affect its operations in the near future and historical losses of its investment and as a result the Company record ed an impairment (Note 3(a)) as it was considered that the loss in the value of its investment was other than temporary . Variable Interest Entities: The Company evaluates financial instruments, service contracts, and other arrangements to determine if any variable interests relating to an entity exist, as the primary beneficiary would be required to include assets, liabilities, and the results of operations of the variable interest entity in its financial statements. For 2016, the Company also considered the amendments under ASU 2015-02, “Consolidation (Topic 810)—Amendments to the Consolidation Analysis”, issued in February 2015. The Company's evaluation did not result in an identification of variable interest entities as of December 31, 2016 and 2015 .
Recent Accounting Pronouncements not yet adopted	Recent Accounting Pronouncement s not yet adopted In July 2015, the FASB issued ASU No. 2015-11 –Inventory. ASU 2015-11 is part of FASB Simplification Initiative. Current guidance requires an entity to measure inventory at the lower of cost or market. Market could be the replacement cost, net realizable value or net realizable value less an approximately normal profit margin. Under this Update, the entities will be required to measure inventory at the lower of cost or net realizable value. Net realizable value is defined as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments under the Update more closely align measurement of inventory in US GAAP with the measurement of inventory in IFRS. For public entities, the amendments of this Update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments of this Update should be applied prospectively with early application permitted. The Company does not expect the adoption of this ASU to have a material impact on Company's results of operations, financial position or cash flows. 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. The Company is analyzing the impact of the adoption of this guidance on the Company's 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 March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU" or "Update") No. 2016-09- Compensation-Stock Compensation – Improvements to Employee Share-Based Payment Accounting (Topic 718) which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, all excess income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess t ax benefits should be classified along with other income tax cash flows as an operating activity. In regards to forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period, however early adoption is permitted. The Company has adopted the provisions of ASU 2016-09, which did not impact its consolidated financial statements and notes disclosures. In May and April 2016, the FASB issued two Updates with respect to Topic 606: ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” and ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” The amendments in these Updates do not change the core principle of the guidance in Topic 606, which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services by applying the following steps: (1) Identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The amendments in Update 2016-10 simply clarify the following two aspects of Topic 606: (1) identifying performance obligations and (2) licensing implementation guidance. The amendments in Update 2016-12 similarly affect only certain narrow aspects of Topic 606; namely, (1) “Assessing the Collectibility Criterion in Paragraph 606-10-25-1(e) and Accounting for Contracts That Do Not Meet the Criteria for Step 1 (Applying Paragraph 606-10-25-7),” (2) “Presentation of Sales Taxes and Other Similar Taxes Collected from Customers,” (3) “Noncash Consideration,” (4) “Contract Modifications at Transition,” (5) “Completed Contracts at Transition,” and (6) “Technical Correction.” The amendments in these Updates also affect the guidance in Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in these Updates are the same as the effective date and transition requirements in Topic 606 (and any other Topic amended by Update 2014-09). Accounting Standards Update 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” has deferred the effective date of Update 2014-09 for public business entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted. The new revenue standard may be applied using either of the following transition methods: (1) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (2) a modified retrospective approach with the cumulative effect of initially adopting the standard recognized at the date of adoption (which includes additional footnote disclosures). The Company will adopt the standard in the first quarter of 2018 and preliminarily expect to use the modified retrospective method. Currently, the Company is in the process of evaluating the impact of the standard and of reviewing historical contracts to quantify the impact that the adoption of the standard will have on sp ecific performance obligations. 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. The Company is in the process of assessing the impact of the amendment of this Update on the Company's consolidated financial position and performance. 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 corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); 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, howe ver early adoption is permitted. The Company is currently evaluating the provisions of this guidance and assessing its impact on its consolidated financial statements and notes disclosures. 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. The Company is currently evaluating the provisions of this guidance and assessing its impact on its consolidated financial statements and notes disclosures.

Earnings Per Share [Abstract]
Loss Per Share	12. L oss per S hare All common shares issued (including the restricted shares issued under the Company's Incentive Plan s ) are the Company's common stock and have equal rights to vote and participate in dividends upon their vesting. The calculation of basic earnings /( loss) per share does not treat the non-vested shares (not considered participating securities) as outstanding until the time/service-based vesting restriction has lapsed. For the purpose of calculating diluted earnings per share the weighted average number of diluted shares outstanding includes the incremental shares assumed issued determined in accordance with the treasury stock method. For 2016 , 2015 and 2014 and on the basis that the Company incurred losses, the effect of incremental shares would be anti-dilutive and t herefore basic and diluted loss per share was the same. Profit or loss attributable to common equity holders is adjusted by the amount of dividends on Series B Preferred Stock as follows: 2016 2015 2014 Net loss $ (164,237) $ (64,713) $ (10,268) Less dividends on series B preferred shares $ (5,769) $ (5,769) $ (5,080) Net loss attributed to common stockholders (170,006) (70,482) (15,348) Weighted average number of common shares, basic and diluted 80,441,517 79,518,009 81,292,290 Loss per share, basic and diluted $ (2.11) $ (0.89) $ (0.19)

Income Taxes [Abstract]
Income Taxes	13. Income Taxes Under the laws of the countries of the companies' incorporation and / or vessels' registration, 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 operations . Pursuant to the Internal Revenue Code of the United States (the “Code”), U.S. source income from the international operations of ships is generally exempt from U.S. tax if the company operating the ships meets both of the following requirements, (a) the Company is organized in a foreign country that grants an equivalent exception to corporations organized in the United States and (b) either ( i ) more than 50% of the value of the Company's stock is owned, directly or indirectly, by individuals who are “residents” of the Company's country of organization or of another foreign country that grants an “equivalent exemption” to corporations organized in the United States (50% Ownership Test) or (ii) the Company's stock is “primarily and regularly traded on an established securities market” in its country of organization, in another country that grants an “equivalent exemption” to United States corporations, or in the United States (Publicly -Traded Test). Notwithstanding the foregoing, the regulations provide, in pertinent part, that each class of the Company's stock will not be considered to be “regularly traded” on an established securities market for any taxable year in which 50% or more of the vote and value of the outstanding shares of such class are owned, actually or constructively under specified stock attribution rules, on more than half the days during the taxable year by persons who each own 5% or more of the value of such class of the Company's outstanding stock, (“5 Percent Override Rule”). The Company and each of its subsidiaries expects to qualify for this statutory tax exemption for the 2016, 2015 and 2014 taxable years, and the Company takes this position for United States federal income tax return reporting purposes. However, there are factual circumstances beyond the Company's control that could cause it to lose the benefit of this tax exemption in future years and thereby become subject to United States federal income tax on its United States source income such as if, for a particular taxable year, other shareholders with a five percent or greater interest in the Company's stock were, in combination with the Company's existing 5% shareholders, to own 50% or more of the Company's outstanding shares of its stock on more than half the days during the taxable year. The Company estimates that since no more than the 50% of its shipping income would be treated as being United States source income, the effective tax rate is expected to be 2% and accordingly it anticipates that the impact on its results of operations will not be material. The Company believes that it satisfies the Publicly-Traded Test and all of its United States source shipping income is exempt from U.S. federal income tax. Based on its U.S. source Shipping Income for 2016, 2015 and 2014, the Company would be subject to U.S. federal income tax of approximately $80 , $166 and $246, respectively, in the absence of an exemption under Section 883.

Financial Instruments	14 . Financial Instruments and Fair Value Disclosures The carrying values of temporary cash investments, accounts receivable and accounts payable approximate their fair value due to the short-term nature of these financial instruments. The fair values of long-term bank loans approximate the recorded values, due to their variable interest rates. The fair value of long-term loan receivable from Diana Containerships also approximate s its recorded value , due to its variable interest rate . The fair value of the Senior Unsecured Notes (Note 8) having a fixed interest rate amounted to $52,169 as of December 31, 2016 , and was determined through the Level 1 input of the fair value hierarchy as defined in FASB guidance for Fair Value Measurements based on the quoted price of the instrument on that date as stated under the ticker Symbol “DSXN” on the NYSE. The Company is exposed to interest rate fluctuations associated with its variable rate borrowings and its objective is to manage the impact of such fluctuations on earnings and cash flows of its borrowings. In May 2009 the Company entered into a five-year zero cost collar agreement (novated in March 2012), with a floor at 1% and a cap at 7.8% of a notional amount of $100,000 to manage its exposure to interest rate changes related to its borrowings. The collar agreement, which matured on May 27, 2014, was used as an economic hedge agreement and did not meet the criteria for hedge accounting; therefore, the changes in its fair value were recognized in earnings. During 2014, the Company incurred gain of $68, separately presented as “Gain from derivative instruments” in the related accompanying consolidated statement of operations. Currently the company does not have any derivative instruments to manage such fluctuations.

Significant Accounting Policies and Recent Accounting Pronouncements [Abstract]
Principles of Consolidation	(a) Principles of Consolidation: The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, and include the accounts of Diana Shipping Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.
Use of Estimates	(b) Use of Estimates: The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Other Comprehensive Income / (Loss)	(c) Other Comprehensive Income / (loss): The Company separately presents certain transactions, which are recorded directly as components of stockholders’ equity. Other Comprehensive Income / (Loss) is presented in a separate statement.
Foreign Currency Translation	(d) Foreign Currency Translation: The functional currency of the Company is the U.S. dollar because the Company’s vessels operate in international shipping markets, and therefore primarily transact business in U.S. dollars. The Company’s accounting records are maintained in U.S. dollars. Transactions involving other currencies during the year are converted into U.S. dollars using the exchange rates in effect at the time of the transactions. At the balance sheet dates, monetary assets and liabilities which are denominated in other currencies are translated into U.S. dollars at the year-end exchange rates. Resulting gains or losses are reflected separately in the accompanying consolidated statements of operations.
Cash and Cash Equivalents	(e) Cash and Cash Equivalents: The Company considers highly liquid investments such as time deposits, certificates of deposit and their equivalents with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents may also include compensating cash balances kept against the Company’s loan facilities that are not deemed to be sufficiently material to require segregation on the balance sheet. As of December 31, 2016 and 2015, such balances are separately presented as “Compensating cash balance” and consist of minimum cash deposits required to be maintained at all times under the Company’s loan facilities (Note 8).
Accounts Receivable, Trade	(f) Accounts Receivable, Trade: The amount shown as accounts receivable, trade, at each balance sheet date, includes receivables from charterers for hire, ballast bonus billings, if any, hold cleanings and extra voyage insurance, net of any provision for doubtful accounts. At each balance sheet date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate provision for doubtful accounts. No provision for doubtful accounts was established as of December 31, 2016 and 2015.
Loan Receivable from Related Parties	(g) Loan Receivable from Related Parties : The amounts shown as Due from related parties, current and non-current, in the consolidated balance sheet as at December 31, 2016 and 2015, (Note 4(b)) represent amounts receivable from Diana Containerships Inc. with respect to a loan agreement with a wholly owned subsidiary of Diana Containerships Inc., net of any provision for credit losses. Interest income and fees, deriving from the agreement are recorded in the accounts as incurred. At each balance sheet date, amounts due under the aforementioned loan agreement are assessed for purposes of determining the appropriate provision for credit losses. As at December 31, 2016 and 2015, the Company assessed the ability of Diana Containerships to meet its obligations under the loan agreement by taking into consideration existing economic conditions, the current financial condition of Diana Containerships Inc. historical losses, and other risks/factors that may affect its future financial condition and its ability to meet its obligations. As a result of this assessment, the Company did not record any provision for credit losses, as it determined that Diana Containerships will be able to meet its obligations under the loan in the near future.
Inventories	(h) Inventories : Inventories consist of lubricants and victualling which are stated at the lower of cost or market. Cost is determined by the first in, first out method. Inventories may also consist of bunkers when on the balance sheet date a vessel remains idle. Bunkers are also stated at the lower of cost or market and cost is determined by the first in, first out method.
Vessel Cost	(i) Vessel Cost: Vessels are stated at cost which consists of the contract price and any material expenses incurred upon acquisition or during construction. Expenditures for conversions and major improvements are also capitalized when they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels; otherwise these amounts are charged to expense as incurred. Interest cost incurred during the assets' construction periods that theoretically could have been avoided if expenditure for the assets had not been made is also capitalized. The capitalization rate, applied on accumulated expenditures for the vessel, is based on interest rates applicable to outstanding borrowings of the period.
Property and equipment	(j) Property and equipment: The Company owns the land and building where its offices are located. Land is presented in its fair value on the date of acquisition and it is not subject to depreciation. The building has an estimated useful life of 55 years with no residual value. Depreciation is calculated on a straight-line basis. Equipment consists of office furniture and equipment, computer software and hardware and vehicles which consist of motor scooters and a car. The useful life of the car is 10 years, of the office furniture, equipment and the scooters is 5 years; and of the computer software and hardware is 3 years. Depreciation is calculated on a straight-line basis.
Impairment of Long-Lived Assets	(k) Impairment of Long-Lived Assets: Long-lived assets (vessels, land, and building) and certain identifiable intangibles held and used by an entity are reviewed for impairment whenever events or changes in circumstances (such as market conditions, obsolesce or damage to the asset, potential sales and other business plans) indicate that the carrying amount of the assets may not be recoverable. When the estimate of undiscounted projected net operating cash flows, excluding interest charges, expected to be generated by the use of the asset over its remaining useful life and its eventual disposition is less than its carrying amount, the Company should evaluate the asset for an impairment loss. Measurement of the impairment loss is based on the fair value of the asset. The Company determines the fair value of its assets based on management estimates and assumptions and by making use of available market data and taking into consideration third party valuations. With respect to the vessels, the Company determines undiscounted projected net operating cash flows for each vessel by considering the historical and estimated vessels’ performance and utilization, assuming (i) future revenues calculated for the fixed days, using the fixed charter rate of each vessel from existing time charters and for the unfixed days, the most recent 10 year average of historical 1 year time charter rates available for each type of vessel over the remaining estimated life of each vessel, net of brokerage commissions. Historical ten-year blended average one-year time charter rates are in line with the Company’s overall chartering strategy, they reflect the full operating history of vessels of the same type and particulars with the Company’s operating fleet and they cover at least a full business cycle; (ii) expected outflows for scheduled vessels’ maintenance; (iii) vessel operating expenses increasing annually by an annual inflation rate of 3%, which approximates current projections for global inflation rate; (iv) effective fleet utilization of 98% taking into account the period each vessel is expected to remain off hire for scheduled maintenance (dry docking and special surveys) and 1% off hire days (other than for dry docking and special surveys) each year, assumptions in line with the Company’s historical performance and its expectations for future fleet utilization under its current fleet deployment strategy. The Company concluded based on this exercise that step two of the impairment analysis was not required and has not identified any facts or circumstances that would require the write down of vessel values as at December 31, 2016 or in the near future and no impairment loss has been identified or recorded for 2016, 2015 and 2014. With respect to the land and building, the Company determines undiscounted projected net operating cash flows by considering an estimated monthly rent the Company would have to pay in order to lease a similar property, during the useful life of the building. As at December 31, 2016, 2015 and 2014, no impairment loss was identified or recorded and the Company has not identified any other facts or circumstances that would require the write down of the value of its land or building in the near future.
Vessel Depreciation	(l) Vessel Depreciation : Depreciation is computed using the straight-line method over the estimated useful life of the vessels, after considering the estimated salvage (scrap) value. Each vessel’s salvage value is equal to the product of its lightweight tonnage and estimated scrap rate. Management estimates the useful life of the Company’s vessels to be 25 years from the date of initial delivery from the shipyard. Second hand vessels are depreciated from the date of their acquisition through their remaining estimated useful life. When regulations place limitations over the ability of a vessel to trade on a worldwide basis, its remaining useful life is adjusted at the date such regulations are adopted.
Accounting for Dry-Docking Costs	(m) Accounting for Dry-Docking Costs : The Company follows the deferral method of accounting for dry-docking costs whereby actual costs incurred are deferred and are amortized on a straight-line basis over the period through the date the next dry-docking is scheduled to become due. Unamortized dry-docking costs of vessels that are sold are written off and included in the calculation of the resulting gain or loss in the year of the vessel’s sale.
Financing Costs	(n) Financing Costs : Fees paid to lenders for obtaining new loans or refinancing existing ones are deferred and recorded as a contra to debt. Other fees paid for obtaining loan facilities not used at the balance sheet date are capitalized as deferred financing costs. Fees relating to drawn loan facilities are amortized to interest and finance costs over the life of the related debt using the effective interest method and fees incurred for loan facilities not used at the balance sheet date are amortized using the straight line method according to their availability terms. Unamortized fees relating to loans repaid or refinanced as debt extinguishment are expensed as interest and finance costs in the period the repayment or extinguishment is made. Loan commitment fees are charged to expense in the period incurred, unless they relate to loans obtained to finance vessels under construction, in which case they are capitalized to the vessels’ cost.
Concentration of Credit Risk	(o) Concentration of Credit Risk: Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist principally of cash, trade accounts receivable and the loan receivable from a related party. The Company places its temporary cash investments, consisting mostly of deposits, with various qualified financial institutions and performs periodic evaluations of the relative credit standing of those financial institutions that are considered in the Company’s investment strategy. The Company limits its credit risk with accounts receivable by performing ongoing credit evaluations of its customers’ financial condition and generally does not require collateral for its accounts receivable and does not have any agreements to mitigate credit risk. The Company limits its credit risk with the loan receivable by performing ongoing credit evaluations of Diana Containerships’ financial condition. The loan agreement is guaranteed by Diana Containerships but does not have any collateral and the Company has not entered into any agreement to mitigate credit risk.
Accounting for Revenues and Expenses	(p) Accounting for Revenues and Expenses: Revenues are generated from time charter agreements and are usually paid fifteen days in advance. Time charter agreements with the same charterer are accounted for as separate agreements according to the terms and conditions of each agreement. Time charter revenues are recorded over the term of the charter as service is provided. Income representing ballast bonus payments by the charterer to the vessel owner is recognized in the period earned. Revenues from time charter agreements providing for varying annual rates over their term are accounted for on a straight line basis. Compensation due to earlier redelivery than the minimum period agreed in the charter party is recognized in the period earned. Deferred revenue includes cash received prior to the balance sheet date for which all criteria to recognize as revenue have not been met. Deferred revenue may also include deferred revenue resulting from charter agreements providing for varying annual rates, which are accounted for on a straight line basis, or the unamortized balance of the liability associated with the acquisition of second-hand vessels with time charters attached which were acquired at values below fair market value at the date the acquisition agreement is consummated. Voyage expenses, primarily consisting of commissions, port, canal and bunker expenses that are unique to a particular charter, are paid for by the charterer under time charter arrangements, except for commissions, which are always paid for by the Company, regardless of charter type. All voyage and vessel operating expenses are expensed as incurred, except for commissions. Commissions are deferred over the related voyage charter period to the extent revenue has been deferred since commissions are due as the Company’s revenues are earned.
Repairs and Maintenance	(q) Repairs and Maintenance: All repair and maintenance expenses including underwater inspection expenses are expensed in the year incurred. Such costs are included in vessel operating expenses in the accompanying consolidated statements of operations.
Earnings / (loss) per Common Share	(r) Earnings / (loss) per Common Share: Basic earnings / (loss) per common share are computed by dividing net income / (loss) available to common stockholders by the weighted average number of common shares outstanding during the year. Diluted earnings per common share, reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised.
Segmental Reporting	(s) Segmental Reporting: The Company has determined that it operates under one reportable segment, relating to its operations of the dry-bulk vessels. The Company reports financial information and evaluates the operations of the segment by charter revenues and not by the length of ship employment for its customers, i.e. spot or time charters. The Company does not use discrete financial information to evaluate the operating results for each such type of charter. Although revenue can be identified for these types of charters, management cannot and does not identify expenses, profitability or other financial information for these charters. As a result, management, including the chief operating decision maker, reviews operating results solely by revenue per day and operating results of the fleet. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable.
Fair Value Measurements	(t) Fair Value Measurements : The Company classifies and discloses its assets and liabilities carried at the fair value in one of the following categories: Level 1: Quoted market prices in active markets for identical assets or liabilities; Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data; Level 3: Unobservable inputs that are not corroborated by market data.
Share Based Payments	(u) Share Based Payments: The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost is recognized over the period during which an employee is required to provide service in exchange for the award—the requisite service period (usually the vesting period). No compensation cost is recognized for equity instruments for which employees do not render the requisite service. Employee share purchase plans will not result in recognition of compensation cost if certain conditions are met. The Company initially measures the cost of employee services received in exchange for an award or liability instrument based on its current fair value; the fair value of that award or liability instrument is re-measured subsequently at each reporting date through the settlement date. Changes in fair value during the requisite service period are recognized as compensation cost over that period with the exception of awards granted in the form of restricted shares which are measured at their grant date fair value and are not subsequently re-measured. The grant-date fair value of employee share options and similar instruments are estimated using option-pricing models adjusted for the unique characteristics of those instruments (unless observable market prices for the same or similar instruments are available). If an equity award is modified after the grant date, incremental compensation cost will be recognized in an amount equal to the excess of the fair value of the modified award over the fair value of the original award immediately before the modification.
Derivatives	(v) Derivatives: The Company is exposed to interest rate fluctuations associated with its variable rate borrowings and its objective is to manage the impact of such fluctuations on earnings and cash flows of its borrowings. In this respect, in May 2009, the Company entered into a five-year zero cost collar agreement, novated in March 2012, and terminated in May 2014, to manage its exposure to interest rate changes related to its borrowings. The collar agreement was considered as an economic hedge agreement as it did not meet the criteria of hedge accounting; therefore, the changes in its fair value were recognized in earnings (Note 14).
Equity method investments	(w) Equity method investments: Investments in common stock in entities over which the Company exercises significant influence, but does not exercise control are accounted for by the equity method of accounting. Under this method, the Company records such an investment at cost and adjusts the carrying amount for its share of the earnings or losses of the entity subsequent to the date of investment and reports the recognized earnings or losses in income. Dividends received, if any, reduce the carrying amount of the investment. When the Company’s share of losses in an entity accounted for by the equity method equals or exceeds its interest in the entity, the Company does not recognize further losses, unless the Company has made advances, incurred obligations and made payments on behalf of the entity. The Company also evaluates whether a loss in value of an investment that is other than a temporary decline should be recognized. Evidence of a loss in value might include absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity that would justify the carrying amount of the investment. In 2016, the Company assessed the financial condition of Diana Containerships Inc., the market conditions that could affect its operations in the near future and historical losses of its investment and as a result the Company recorded an impairment (Note 3(a)) as it was considered that the loss in the value of its investment was other than temporary.
Variable Interest Entities	(x) Variable Interest Entities: The Company evaluates financial instruments, service contracts, and other arrangements to determine if any variable interests relating to an entity exist, as the primary beneficiary would be required to include assets, liabilities, and the results of operations of the variable interest entity in its financial statements. For 2016, the Company also considered the amendments under ASU 2015-02, “Consolidation (Topic 810)—Amendments to the Consolidation Analysis”, issued in February 2015. The Company’s evaluation did not result in an identification of variable interest entities as of December 31, 2016 and 2015.
Recent Accounting Pronouncements not yet adopted	Recent Accounting Pronouncement s not yet adopted In July 2015, the FASB issued ASU No. 2015-11 –Inventory. ASU 2015-11 is part of FASB Simplification Initiative. Current guidance requires an entity to measure inventory at the lower of cost or market. Market could be the replacement cost, net realizable value or net realizable value less an approximately normal profit margin. Under this Update, the entities will be required to measure inventory at the lower of cost or net realizable value. Net realizable value is defined as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments under the Update more closely align measurement of inventory in US GAAP with the measurement of inventory in IFRS. For public entities, the amendments of this Update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments of this Update should be applied prospectively with early application permitted. The Company does not expect the adoption of this ASU to have a material impact on Company's results of operations, financial position or cash flows. 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. The Company is analyzing the impact of the adoption of this guidance on the Company's 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 March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU" or "Update") No. 2016-09- Compensation-Stock Compensation – Improvements to Employee Share-Based Payment Accounting (Topic 718) which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, all excess income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess t ax benefits should be classified along with other income tax cash flows as an operating activity. In regards to forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period, however early adoption is permitted. The Company has adopted the provisions of ASU 2016-09, which did not impact its consolidated financial statements and notes disclosures. In May and April 2016, the FASB issued two Updates with respect to Topic 606: ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” and ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” The amendments in these Updates do not change the core principle of the guidance in Topic 606, which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services by applying the following steps: (1) Identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The amendments in Update 2016-10 simply clarify the following two aspects of Topic 606: (1) identifying performance obligations and (2) licensing implementation guidance. The amendments in Update 2016-12 similarly affect only certain narrow aspects of Topic 606; namely, (1) “Assessing the Collectibility Criterion in Paragraph 606-10-25-1(e) and Accounting for Contracts That Do Not Meet the Criteria for Step 1 (Applying Paragraph 606-10-25-7),” (2) “Presentation of Sales Taxes and Other Similar Taxes Collected from Customers,” (3) “Noncash Consideration,” (4) “Contract Modifications at Transition,” (5) “Completed Contracts at Transition,” and (6) “Technical Correction.” The amendments in these Updates also affect the guidance in Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in these Updates are the same as the effective date and transition requirements in Topic 606 (and any other Topic amended by Update 2014-09). Accounting Standards Update 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” has deferred the effective date of Update 2014-09 for public business entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted. The new revenue standard may be applied using either of the following transition methods: (1) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (2) a modified retrospective approach with the cumulative effect of initially adopting the standard recognized at the date of adoption (which includes additional footnote disclosures). The Company will adopt the standard in the first quarter of 2018 and preliminarily expect to use the modified retrospective method. Currently, the Company is in the process of evaluating the impact of the standard and of reviewing historical contracts to quantify the impact that the adoption of the standard will have on sp ecific performance obligations. 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. The Company is in the process of assessing the impact of the amendment of this Update on the Company's consolidated financial position and performance. 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 corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); 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, howe ver early adoption is permitted. The Company is currently evaluating the provisions of this guidance and assessing its impact on its consolidated financial statements and notes disclosures. 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. The Company is currently evaluating the provisions of this guidance and assessing its impact on its consolidated financial statements and notes disclosures.
