Segment Reporting: one one Accounting for Special Survey and Dry-docking Costs: Deferred Finance Charges: ones Accounting for Revenue and Related Expenses: Voyage expenses comprise commissions, bunkers and port expenses and are unique to a particular charter. Commissions in all cases are paid by the Company and are recognized on a pro-rata basis. All other voyage expenses are paid by the charterer under time charter arrangements or by the Company under voyage charter arrangements and are recognized as incurred. Vessel operating expenses comprise all expenses relating to the operation of the vessel, including crewing, repairs and maintenance, insurance, stores, lubricants and miscellaneous expenses. Vessel operating expenses are paid by the Company and are accounted for on an accrual basis. Under a bareboat charter, the charterer assumes responsibility for all voyage and vessel operating expenses, dry-docking expenses and risk of operation. Leasing: one 75% 90% Equity Compensation Plan: 14). Earnings/(Loss) per Share: two Dilution is computed by either the treasury stock method or the two–class 15). Derivatives 815, (i) Hedge Accounting Contracts which meet the strict criteria for hedge accounting are accounted for as cash flow hedges. A cash flow hedge is a hedge of the exposure to variability in cash flows that is attributable to a particular risk associated with a recognized asset or liability, or a highly probable forecasted transaction that could affect profit or loss. The effective portion of the gain or loss on the hedging instrument is recognized directly as a component of “Accumulated other comprehensive income/loss” in equity, while any ineffective portion, if any, is recognized immediately in current period earnings. The Company discontinues cash flow hedge accounting if the hedging instrument expires and it no longer meets the criteria for hedge accounting or designation is revoked by the Company. At that time, any cumulative gain or loss on the hedging instrument recognized in equity is kept in equity until the forecasted transaction occurs. When the forecasted transaction occurs, any cumulative gain or loss on the hedging instrument is recognized in the statement of income. If a hedged transaction is no longer expected to occur, the net cumulative gain or loss recognized in equity is transferred to net profit or loss for the year as a component of “Loss on derivatives”.

All unvested restricted shares are conditional upon the option holder’s continued service as an employee of the Company, or as a director until the applicable vesting date. Until the forfeiture of any restricted shares, the grantee has the right to vote such restricted shares, to receive and retain all regular cash dividends paid on such restricted shares and to exercise all other rights provided that the Company will retain custody of all distributions other than regular cash dividends made or declared with respect to the restricted shares. The Company pays dividends on all restricted shares regardless of whether they have vested and there is no obligation of the employee to return the dividend when employment ceases. The Company did not pay any dividends in the years ended December 31, 2014, 2015 2016. The Company estimates the forfeitures of non-vested share awards to be immaterial and hence accounts for forfeitures as they occur. Management has selected the accelerated method allowed by the guidance with respect to recognizing stock based compensation expense for restricted share awards with graded vesting because it considers this method to better match expense with benefits received. In addition, non-vested awards granted to non-employees are measured at their then-current fair value as of the financial reporting dates until non-employees complete the service.

Earnings Per Share [Text Block] | 15. Earnings/(loss) per share Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per share give effect to all potentially dilutive securities. All of the Company’s shares (including non-vested restricted stock issued under the Plan) participate equally in dividend distributions and in undistributed earnings. The Company applies the two two For purposes of calculating diluted earnings per share, dividends declared during the period for non-vested restricted stock and undistributed earnings allocated to non-vested stock are not deducted from net income as reported since such calculation assumes non-vested restricted stock is fully vested from the grant date. The Company calculates basic and diluted earnings per share as follows: Year Ended December 31, 2014 2015 2016 Numerator Net income/(loss) 12,685,826 2,566,678 (7,798,300 ) Less: Undistributed earnings allocated to non-vested shares (26,357 ) (13,457 ) — Net income/(loss) attributable to common shareholders, basic 12,659,469 2,553,221 (7,798,300 ) Denominator Weighted average number of shares outstanding, basic and diluted 39,305,644 41,315,127 39,824,038 Earnings/(loss) per share, basic and diluted 0.32 0.06 (0.20 ) Non-vested, participating restricted common stock does not have a contractual obligation to share in the 2016 December 31, 2016.

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 have been included in Vessel operating expenses in the 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 certain requirements. Among other things, in order to qualify for this exemption, the Company operating the ships must be incorporated in a country which grants an equivalent exemption from income taxes to U.S. corporations. All the Company’s ship-operating subsidiaries satisfy these initial criteria. In addition, these companies must be more than 50% 50% In addition, the management of the Company believes that by virtue of a special rule applicable to situations where the ship-operating companies are beneficially owned by a publicly traded company like the Company, the more than 50% |

Derivatives, Policy [Policy Text Block] | Derivatives 815, (i) Hedge Accounting Contracts which meet the strict criteria for hedge accounting are accounted for as cash flow hedges. A cash flow hedge is a hedge of the exposure to variability in cash flows that is attributable to a particular risk associated with a recognized asset or liability, or a highly probable forecasted transaction that could affect profit or loss. The effective portion of the gain or loss on the hedging instrument is recognized directly as a component of “Accumulated other comprehensive income/loss” in equity, while any ineffective portion, if any, is recognized immediately in current period earnings. The Company discontinues cash flow hedge accounting if the hedging instrument expires and it no longer meets the criteria for hedge accounting or designation is revoked by the Company. At that time, any cumulative gain or loss on the hedging instrument recognized in equity is kept in equity until the forecasted transaction occurs. When the forecasted transaction occurs, any cumulative gain or loss on the hedging instrument is recognized in the statement of income. If a hedged transaction is no longer expected to occur, the net cumulative gain or loss recognized in equity is transferred to net profit or loss for the year as a component of “Loss on derivatives”.
