New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance (except revenue in the scope of other accounting standards, including standards related to leasing). The standard clarifies the required factors that an entity must consider when recognizing revenue and requires additional disclosures concerning contracts with customers, judgments concerning revenue recognition, and assets recognized for the costs to obtain or fulfill a contract. The standard also provides guidance regarding the measurement of gains and losses relative to the sale of certain nonfinancial assets, including real estate. ASU 2014-09 is effective for the Company beginning January 1, 2018. The Company has performed an initial assessment of ASU 2014-09 and plans to adopt the standard using the modified retrospective approach. Upon adoption of ASU 2016-02 (see below), the majority of our revenue will be subject to the allocation provisions outlined within the revenue standard. The Company is currently evaluating the specific implementation requirements for allocating the consideration within our contracts in accordance with ASU 2014-09 as well as other transactions subject to ASU 2014-09. The Company does not expect the new standard to have a material impact on the measurement and recognition of gains and losses on the sale of properties. In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 is effective for the Company beginning January 1, 2019. Early adoption of ASU 2016-02 is permitted. The standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. For leases in which the Company is the lessor, the standard requires that the lease and non-lease components of the lease agreement should be separated. Revenue related to the lease component of the contract will be recognized on a straight-line basis, while revenue related to the non-lease component will be recognized under the provisions of ASU 2014-09 (see above). For lease agreements longer than one year in which the Company is the lessee, the Company will measure the present value of the future lease payments and recognize a right-of-use asset and corresponding lease liability on its balance sheet. In addition, the new standard states that only direct leasing costs may be capitalized. The Company is evaluating the impact ASU 2016-02 will have on its financial position and results of operations. In March 2016, the FASB issued ASU 2016-05, Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships ("ASU 2016-05"). ASU 2016-05 states that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under FASB Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-05 is effective for the Company beginning January 1, 2017. The Company adopted the standard on a prospective basis. The adoption of ASU 2016-05 did not have a material impact on the Company's financial position or results of operations. In March 2016, the FASB issued ASU 2016-09. ASU 2016-09 is designed to simplify 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. Certain amendments in the standard are applied retrospectively and certain amendments are applied prospectively. The adoption of ASU 2016-09 did not have a material impact on the Company's financial position or results of operations. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 is designed to clarify how entities should classify cash receipts and cash payments in the statement of cash flows. ASU 2016-15 is effective for the Company beginning January 1, 2018. Early adoption of ASU 2016-15 is permitted. The standard requires retrospective application unless it is impracticable to do so. The Company is evaluating the impact ASU 2016-15 will have on its statement of cash flows. In February 2017, the FASB issued ASU 2017-05 Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets ("ASU 2017-05"). ASU 2017-05 is designed to provide guidance on how to recognize gain and losses on sales, including partial sale, of nonfinancial assets to noncustomers. ASU 2017-05 is effective for the Company beginning January 1, 2018. Early adoption is permitted but the standard is required to be adopted concurrently with ASU 2014-09. The Company is evaluating the impact ASU 2017-05 will have on the Company's financial position and results of operations.
