| Accounting Policies [Abstract] | |
| Principles of Consolidation | Pr inciples 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 Containerships Inc. and its wholly-owned subsidiaries referred to in Note 1 above. All significant intercompany balances and transactions have been eliminated upon consolidation. |
| Use of Estimates | 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 | Other Comprehensive Income / (loss) : The Company follows the provisions of Accounting Standard Codification (ASC) 220, “Comprehensive Income”, which requires separate presentation of certain transactions, which are recorded directly as components of stockholders' equity . The Company presents Other Comprehensive Income / (Loss) in a separate statement according to ASU 2011-05. |
| Foreign Currency Translation | Foreign Currency Translation: The functional currency of the Company is the U.S. Dollar because the Company operate s its vessels in international shipping markets, and therefore , primarily transact s business in U.S. Dollars. The Company's account ing records are maintained in U.S. Dollars. Transactions involving other currencies during the years presented are converted into U.S. Dollars using the exchange rates in effect at the time of the transact ions. At the balance sheet date s , monetary assets and liabilities which are denominated in other currencies are translated into U.S. Dollars at the period -end exchange rates. Resulting gains or losses are reflected sepa rately in the accompanying consolidated statement s of operations . |
| Cash and Cash Equivalents | 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. |
| Restricted Cash | Restricted Cash : Restricted cash include s minimum cash deposits required to be maintained under the Company's borrowing arrangement s . |
| Accounts Receivable, Trade | Accounts Receivable, Trade: The account includes receivables from charterers for hire, freight and demurrage billings. 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 has been made as of December 31 , 2015 and 2014 . |
| Inventories | 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 the vessel operates under freight charter or when on the balance sheet date a vessel has been redelivered by her previous charterers and h as not yet been delivered to new charterers , or remains idle. Bunkers are also stated at the lower of cost or market and cost is determined by the first in, first out method. |
| Prepaid/Deferred Charter Revenue | Prepaid/Deferred Charter Revenue: The Company records identified assets or liabilities associated with the acquisition of a vessel at their relative fair value, determined by reference to market data. The Company values any asset or liability arising from the market value of the time charters assumed when a vessel is acquired. The amount to be recorded as an asset or liability at the date of vessel delivery is based on the difference between the current fair market value of the charter and the net present value of future contractual cash flows. In determining the relative fair value, when the present value of the contractual cash flows of the time charter assumed is different than its current fair value, the difference, capped to the excess between the acquisition cost and the vessel's fair value on a charter free basis, is recorded as prepaid charter revenue or as deferred revenue, respectively. Such assets and liabilities, respectively, are amortized as a reduction of, or an increase in, revenue over the period of the time charter assumed. |
| Property And Equipment | Property and E quipment: The Company acquired in December 2014 a plot of land , described in Note 5. Land is presented at its fair value on the date of acquisition and it is not subject to depreciation , but it qualifies to be reviewed for impairment . Equipment consists of office furniture and equipment and computer software and hardware. The useful life of the office furniture and equipment is 5 years and the computer software and hardware is 3 years. Depreciation is calculated on a straight-line basis. |
| Vessel Cost | Vessel Cost: Vessels are stated at cost which consists of the contract price and costs incurred upon acquisition or delivery of a vessel from a shipyard. Subsequent expenditures for conversions and major improvements are also capitalized when they appreciably extend the life, increase the earnings capacity or improve the efficiency or safety of the vessels; otherwise these amounts are charged to expense as incurred. |
| Vessel Depreciation | Vessel Depreciation: The Company depreciates containership vessels on a straight-line basis over their estimated useful lives, after considering the estimated salvage value. Each vessel's salvage value is the product of her light - weight tonnage and estimated scrap rate, which is estimated at $0.35 per light - weight ton for all vessels in the fleet . Management estimates the useful life of the Company's vessels to be 30 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 on the ability of a vessel to trade on a worldwide basis, the vessel's useful life is adjusted at the date such regulations are adopted. |
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets: The Company follows ASC 360-10-40 “Impairment or Disposal of Long-Lived Assets”, which addresses financial accounting and reporting for the impairment or disposal of long-lived assets. The Company reviews vessels for impairment whenever events or changes in circumstances indicate that the c a rrying amount of a vessel may not be recoverable. When the estimate of future undiscounted net operating cash flows, excluding interest charges, expected to be generated by the use of the vessel over her remaining useful life and her event ual disposition is less than her carrying amount, the Company evaluates the vessel for impairment loss. Measurement of the impairment loss is based on the fair value of the vessel. The fair value of the vessel is determined based on management estimates and assumptions and by making use of available market data and third party valuations. The Company evaluates the carrying amounts and periods over which vessels are depreciated to determine if events have occurred which would require modification to their carrying values or useful lives. In evaluating useful lives and carrying values of long-lived assets, management reviews certain indicators of potential impairment, such as undiscounted projected operating cash flows, vessel sales and purchases, business plans and overall market conditions. The current conditions in the containerships market with decreased charter rates and decreased vessel market values are conditions that the Company considers indicators of a potential impairment. In developing estimates of future undiscounted cash flows, the Company makes assumptions and estimates about the vessels' future performance, with the significant assumptions being related to charter rates, fleet utilization, vessels' operating expenses, vessels' residual value and the estimated remaining useful life of each vessel. The assumptions used to develop estimates of future undiscounted cash flows are based on historical trends as well as future expectations. The Company determines undiscounted projected net operating cash flows for each vessel and compares it to the vessel's carrying value. The projected net operating cash flows are determined by considering the historical and estimated vessels' performance and utilization, the charter revenues from existing time charters for the fixed fleet days and an estimated daily time charter equivalent for the unfixed days (based , to the extent applicable, on the most recent 10 year average historical 6-12 months time charter rates available for each type of vessel, considering also current market rates) over the remaining estimated life of each vessel, net of commissions, expected outflows for scheduled vessels' maintenance and vessel operating expenses assuming an average annual inflation rate of 3%. Effective fleet utilization is assumed to 98% in the Company's exercise, taking into account the period(s) each vessel is expected to undergo her scheduled maintenance (dry docking and special surveys), as well as an estimate of 1% off hire days each year, assumptions in line with the Company's historical performance. The review of the vessel's carrying amounts in connection with the estimated recoverable amount s for the year ended December 31, 2014 did not result in an indication of impairment , while i n 2015 and 2013, the above mentioned review indicated for certain of the Company's vessels impairment charges, which are separately reflected in the accompanying consolidated statements of operations (Note 4) . |
| Assets Held For Sale | Assets held for sale: It is the Company's policy to dispose of vessels and other fixed assets when suitable opportunities occur and not necessarily to keep them until the end of their useful life. The Company classifies assets or assets in disposal groups as being held for sale in accordance with ASC 360-10-45-9 "Long-Lived Assets Classified as Held for Sale", when the following criteria are met: ( i ) management possessing the necessary authority has committed to a plan to sell the asset (disposal group); (ii) the asset (disposal group) is immediately available for sale on an "as is" basis; (iii) an active program to find the buyer and other actions required to execute the plan to sell the asset (disposal group) have been initiated; (iv) the sale of the asset (disposal group) is probable, and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year; and (v) the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. In case a long-lived asset is to be disposed of other than by sale (for example, by abandonment, in an exchange measured based on the recorded amount of the nonmonetary asset relinquished, or in a distribution to owners in a spinoff) the Company continues to classify it as held and used until its disposal date. Long-lived assets or disposal groups classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell. These assets are not depreciated once they meet the criteria to be held for sale. |
| Accounting for Revenues and Expenses | Accounting for Revenues and Expenses: Revenues are generated from time charter agreements. 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. Revenues from time charter agreements providing for varying annual rates over their term are accounted for on a straight line basis. Income representing ballast bonus payments, in connection with the repositioning of a vessel by the charterer to the vessel owner, are recognized in the period earned. Deferred revenue, if any, includes cash received prior to the balance sheet date for which all criteria for recognition as revenue would not be met, including any deferred revenue resulting from charter agreements providing for varying annual rates, which are accounted for on a straight line basis. Voyage expenses, primarily consisting of port, canal and bunker expenses that are unique to a particular charter, are paid for by the charterer under time charter arrangements or by the Company under voyage 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 revenues are earned. |
| Earnings / loss per Common Share | Earnings / ( Loss ) per Common Share: Basic earnings / ( loss ) per common share are computed by dividing net income / ( loss ) attributable to common stockholders by the weighted average number of common sh ares outstanding during the period . Diluted earnings / ( loss ) per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised. |
| Segmental Reporting | Segmental Reporting: The Company has determined that it operates under one reportable segment, relating to its operations of the container 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. |
| Accounting for Dry-Docking Costs | Accounting for Dry-Docking Costs: The Company follow s the deferral method of accounting for dry-docking costs whereby actual costs incurred are deferred and amortized on a straight-line basis over the period through the date the next dry-docking will be 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 . The u namortized dry-docking cost is reflected in Deferred Charges, net, in the accompanying consolidated balance sheets . |
| Financing Costs | 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 are amortized to interest and finance costs over the life of the related debt using the effective interest method and, for the fees relating to loan facilities not used at the balance sheet date, according to the loan 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. |
| Repairs and Maintenance | Repairs and Maintenance: All repair and maintenance expenses including underwater inspection expenses are expensed in the period incurred. Such costs are included in vessel operating expenses in the accompanying consolidated statements of operations . |
| Share-based Payment | Share Based Payment: ASC 718 “Compensation – Stock Compensation”, requires the Company to measure 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 measure s 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 remeasured 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 va lue 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 is 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. |
| Variable Interest Entities | Variable Interest Entities: ASC 81 0-10-50 “Consolidation of Variable Interest Entities”, addresses the consolidation of business enterprises (variable interest entities) to which the usual condition (ownership of a majority voting interest) of consolidation does not apply. The guidance focuses on financial interests that indicate control. It concludes that in the absence of clear control through voting interests, a company's exposure (variable interest) to the economic risks and potential rewards from the variable interest entity's assets and activities are the best evidence of control. Variable interests are rights and obligations that convey economic gains or losses from changes in the value of the variable interest entity's assets and liabilities. 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. The Company's evaluation did not result in an identification of variable interest entities as of December 31, 2015 and 2014. |
| Fair Value Measurements | Fair Value Measurements: The Company follows the provisions of ASC 820 "Fair Value Measurements and Disclosures", which defines fair value and provides guidance for using fair value to measure assets and liabilities. The guidance creates a fair value hierarchy of measurement and describes fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts. In accordance with the requirements of accounting guidance relating to 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. |
| Concentration of Credit Risk | Concentration of Credit Risk: Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist principally of cash and trade accounts receivable. 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. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements The Financial Accounting Standards Board (“FASB” or the “Board”) and the International Accounting Standards Board (IASB) (collectively, the Boards) jointly issued a standard that will supersede virtually all of the existing revenue recognition guidance in U.S. GAAP and International Financial Reporting Standards, or IFRS, and is effective for annual periods beginning on or after December 15, 2016. The standard establishes a five-step model that will apply to revenue earned from a contract with a customer (with limited exceptions), regardless of the type of revenue transaction or the industry. The standard's requirements will also apply to the recognition and measurement of gains and losses on the sale of some non-financial assets that are not an output of the entity's ordinary activities (e.g., sales of property, plant and equipment or intangibles). Extensive disclosures will be required, including disaggregation of total revenue; information about performance obligations; changes in contract asset and liability account balances between periods and key judgments and estimates. Management is in the process of assessing the impact of the new standard on Company's financial position and performance. In August 2015, the Board issued ASU 2015-14-Revenue From Contracts With Customers that defers the effective period to annual reporting periods beginning after December 15, 2017. In August 2014, the FASB issued Accounting Standards Update ("ASU" or “Update”) No. 2014-15 – Presentation of Financial Statements - Going Concern. ASU 2014-15 provides guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 requires an entity's management to evaluate at each reporting period based on the relevant conditions and events that are known at the date of financial statements are issued, whether there are conditions or events, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued and to disclose the necessary information. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. Management do es 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 2015, the FASB issued the ASU 2015-02, “Consolidation (Topic 810)—Amendments to the Consolidation Analysis”, which amends the criteria for determining which entities are considered VIEs, amends the criteria for determining if a service provider possesses a variable interest in a VIE and ends the deferral granted to investment companies for application of the VIE consolidation model. The ASU is effective for interim and annual periods beginning after December 15, 2015. E arly application is permitted. Management do es not expect the adoption of this ASU to have a material impact on Company's results of operations, financial position or cash flows. 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. Management do es 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. Management 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. |
