On an on-going basis, management evaluates the estimates and judgments, including those related to future drydock dates, the selection of useful lives for tangible assets, expected future cash flows from long-lived assets to support impairment tests, provisions necessary for accounts receivables, provisions for legal disputes, and contingencies. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates under different assumptions and/or conditions.</font></div>falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for the use of estimates in the preparation of financial statements in conformity with generally accepted accounting principles.Reference 1: http://www.xbrl.org/2003/role/presentationRef

Vessels acquired in an asset acquisition or in a business combination are recorded at fair value. Subsequent expenditures for major improvements and upgrading are capitalized, provided they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels.

<div><font style="font-face: Times New Roman" size="2" color="#000000">  Depreciation is computed using the straight line method over the useful life of the vessels, after considering the estimated residual value. Management estimates the residual values of our dry bulk vessels based on a scrap value cost of steel times the weight of the ship noted in lightweight ton (LWT). Residual values are periodically reviewed and revised to recognize changes in conditions, new regulations or other reasons. Revisions of residual values affect the depreciable amount of the vessels and affects depreciation expense in the period of the revision and future periods. Prior to December 31, 2012, management estimated the residual values of its vessels based on a scrap rate of $285 per LWT. Effective January 1, 2013, following management's reassessment after considering current market trends for scrap rates and ten-year average historical scrap rates of the residual values of the Company's vessels, the estimated scrap value per LWT was increased to $340. This change in accounting estimate of scrap value did not materially affect the statement of income and the earnings per unit of the Company in the three and six month period ended June 30, 2013.</font></div>

<div><font style="font-face: Times New Roman" size="2" color="#000000"><i><b></b></i>In February 2013, the Financial Accounting Standards Board (“FASB”) issued amended standards requiring additional disclosures for other comprehensive income. The amended standards require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The amendments apply to all entities that issue financial statements that are presented in conformity with U.S. GAAP and that report items of other comprehensive income. Public companies are required to comply with these amendments for all reporting periods presented, including interim periods. For public entities, the amendments are effective prospectively for reporting periods beginning after December 15, 2012. Navios Partners has adopted the new amendments as of January 1, 2013. The adoption of the new standard did not have a significant impact on Navios Partners' consolidated financial statements.</font></div>falsefalsefalsenonnum:textBlockItemTypenaDisclosure of the adoption of new accounting pronouncements that may impact the entity's financial reporting.No definition available.false0falseACCOUNTING POLICIES (Policies)UnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.navios-mlp.com/role/DisclosureSummaryOfSignificantAccountingPoliciesPolicies14
