Basis of Presentation and Significant Accounting Policies (Policies)	3 Months Ended
Mar. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of Paramount and its consolidated subsidiaries, including the Operating Partnership. All significant inter-company amounts have been eliminated. In our opinion, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and changes in cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016, as filed with the SEC. We have made estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The results of operations for the three months ended March 31, 2017, are not necessarily indicative of the operating results for the full year.
Significant Accounting Policies	Significant Accounting Policies There are no material changes to our significant accounting policies as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016.
Recently Issued Accounting Literature	Recently Issued Accounting Literature In May 2014, the Financial Accounting Standard’s Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, an update to ASC Topic 606, Revenue from Contracts with Customers. ASU 2014-09, as amended, supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of this guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. This guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years, and can be applied using a full retrospective or modified retrospective approach. We will adopt the provisions of ASU 2014-09 on January 1, 2018 using the modified retrospective approach. We have commenced our plan for implementing this guidance and do not believe that the adoption will have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, an update to ASC Topic 842, Leases. ASU 2016-02 amends the existing guidance for lease accounting, including requiring lessees to recognize most leases on their balance sheets. ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either financing or operating and recording a right-of-use asset and a lease liability for all leases with a term greater than 12 months. ASU 2016-02 requires lessors to account for leases using an approach that is substantially similar to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2018, with early adoption permitted. We are currently evaluating the timing of adopting this standard. While we believe that the key changes in ASU 2016-02 relate to the separation of and allocation of consideration to, lease component (rental income) and non-lease components (revenue related to various services we provide), we continue to evaluate the other potential implications that this update will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, an update to ASC Topic 718, Compensation – Stock Compensation. ASU 2016-09 improves the accounting for share-based payments including income tax consequences and the classification of awards as either equity awards or liability awards. ASU 2016-09 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2016, with early adoption permitted. We adopted the provisions of ASU 2016-09 on January 1, 2017. This adoption did not have any impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, an update to ASC Topic 326, Financial Instruments – Credit Losses. ASU 2016-13 requires measurement and recognition of expected credit losses on financial instruments measured at amortized cost at the end of each reporting period rather than recognizing the credit losses when it is probable that the loss has been incurred in accordance with current guidance. ASU 2016-13 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2019, with early adoption permitted for fiscal years beginning after December 15, 2018. We are evaluating the impact of ASU 2016-13 but do not believe the adoption will have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, an update to ASC Topic 230, Statement of Cash Flows to provide guidance for areas where there is diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, with early adoption permitted. We adopted the provisions of ASU 2016-15 retrospectively on January 1, 2017. This adoption did not have a material impact on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-17, an update to ASC Topic 810, Consolidation. ASU 2016-17 requires a reporting entity to consider only its proportionate indirect interest in the VIE held through a common control party in evaluating whether it is the primary beneficiary of a VIE. Currently, ASU 2015-02 requires the reporting entity to treat the common control party’s interest in the VIE as if the reporting entity held the interest itself. ASU 2016-17 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2016. We adopted the provisions of ASU 2016-17 on January 1, 2017. This adoption did not have any impact on our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, an update to ASC Topic 230, Statement of Cash Flows to provide guidance on classification and presentation of changes in restricted cash on the statement of cash flows. ASU 2016-18 requires that an entity’s reconciliation of the beginning-of-period and end-of-period total amounts shown on the statement of cash flows to include restricted cash with cash and cash equivalents. ASU 2016-18 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, with early adoption permitted. We will adopt the provisions of ASU 2016-18 on January 1, 2018. This adoption will impact the presentation of our statement of cash flows, as well as require additional disclosures to reconcile cash and cash equivalents and restricted cash on our balance sheet to our statement of cash flows. In January 2017, the FASB issued ASU 2017-01, an update to ASC Topic 805, Business Combinations. ASU 2017-01 narrows the definition of a business and provides a framework for making reasonable judgments about whether a transaction involves an asset or a business. ASU 2017-01 clarifies that when substantially all the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. ASU 2017-01 also requires that a set cannot be considered a business unless it includes, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output. ASU 2017-01 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, with early adoption permitted for transactions (i.e., acquisitions or dispositions) that occurred before the issuance date or effective date of the standard if the transactions were not reported in financial statements that have been issued or made available for issuance. We adopted the provisions of ASU 2017-01 on October 1, 2016 and concluded that the acquisition of our One Front Street property in December 2016 did not meet the definition of a business and was treated as an asset acquisition. In February 2017, the FASB issued ASU 2017-05, an update to ASC Topic 610, Other Income. ASU 2017-05 clarifies the scope and accounting for derecognition of a nonfinancial asset. ASU 2017-05 eliminates the guidance in ASC 360-20 specific to real estate sales and partial sales. ASU 2017-05 also defines “in-substance nonfinancial assets” and includes guidance on partial sales of nonfinancial assets. ASU 2017-05 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017, with early adoption permitted for entities concurrently early adopting ASU 2014-09. We are evaluating the impact of ASU 2017-05 but do not believe that the adoption will have a material impact on our consolidated financial statements.
