Recent Accounting Pronouncements [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014 the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 provides a principles-based approach for a broad range of revenue generating transactions, including the sale of real estate, which will generally require more estimates, judgment and disclosures than under current guidance. In August 2015 the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09. ASU 2014-09 is now effective for public entities for annual periods beginning after December 15, 2017, including interim periods therein. The Company plans on adopting this standard using the modified retrospective method on January 1, 2018. The ASU provides for revenues from leases to continue to follow the guidance in Topics 840 and 842 and provides for loans to follow established guidance in Topic 310. Because this ASU specifically excludes these areas of our operations from its scope, we do not expect any impact to our accounting for lease revenue and interest income to result from the ASU. Additionally, the other significant types of contracts in which we engage, sales of real estate to customers, typically never remain executory across points in time. Because all performances obligations from these contracts would fall within a single period, the timing of our revenue recognition from sales of real estate is not expected to be affected by the ASU. We are in the initial stages of our evaluation of the ASU, whose eventual adoption is not expected to have a material impact on the timing and measurement of the Company’s income. In February 2016 the FASB issued ASU 2016-02, Leases. Public companies will be required to apply ASU 2016-02 for all accounting periods beginning after December 15, 2018 - for calendar-year REITs this means application will be required beginning January 1, 2019. Early adoption is permitted. All leases with lease terms greater than one year are subject to ASU 2016-02 , including leases in place as of the adoption date. Management expects that, because of the ASU 2016-02’s emphasis on lessee accounting, ASU 2016-02 will not have a material impact on our accounting for leases. Consistent with present standards, NHI will continue to account for lease revenue on a straight-line basis for most leases. Also consistent with NHI’s current practice, under ASU 2016-02 only initial direct costs that are incremental to the lessor will be capitalized. In February 2016 the FASB issued ASU 2016-02, Leases.

Also consistent with NHI’s current practice, under ASU 2016-02 only initial direct costs that are incremental to the lessor will be capitalized. We are in the initial stages of evaluating the extent of the effects, if any, that adopting the provisions of ASU 2016-12 in 2019 will have on NHI. In June 2016 the FASB issued ASU 2016-13, Financial Instruments - Credit Losses. ASU 2016-13 will require more timely recognition of credit losses associated with financial assets. While current GAAP includes multiple credit impairment objectives for instruments, the previous objectives generally delayed recognition of the full amount of credit losses until the loss was probable of occurring. The amendments in ASU 2016-13, whose scope is asset-based and not restricted to financial institutions, eliminate the probable initial recognition threshold in current GAAP and, instead, reflect an entity’s current estimate of all expected credit losses. Previously, when credit losses were measured under GAAP we generally only considered past events and current conditions in measuring the incurred loss. The amendments in ASU 2016-13 broaden the information that we must consider in developing our expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss that will be more useful to users of the financial statements. ASU 2016-13 is effective for public entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Because we are likely to continue to invest in loans and generate receivables, adoption of ASU 2016-13 in 2020 will have some effect on our accounting for these investments, though the nature of those effects will depend on the composition of our loan portfolio at that time; accordingly, we are in the initial stages of evaluating the extent of the effects, if any, that adopting the provisions of ASU 2016-13 in 2020 will have on NHI. In November 2016 the FASB issued ASU 2016-18, Restricted Cash. ASU 2016-18 will require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents, generally by requiring the inclusion of restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update do not provide a definition of restricted cash or restricted cash equivalents. ASU 2016-18 is effective for public entities for fiscal years beginning after December 15, 2017, including interim periods. The adoption of ASU 2016-18 is not expected to have a material effect on our consolidated financial statements. In January 2017 the FASB issued ASU 2017-01, Clarifying the Definition of a Business. ASU 2017-01 will narrow the definition of a business in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. Currently the definition of outputs contributes to broad interpretations of the definition of a business. Additionally, the Standard provides that when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the set is not a business. For purposes of this test, land and buildings can be combined along with the intangible assets for any in-place leases. For most of NHI’s acquisitions of investment property, this screen would be met and, therefore, not meet the definition of a business. ASU 2017-01 is effective for public entities for fiscal years beginning after December 15, 2017, including interim periods. Early application of this standard is generally allowed for acquisitions acquired after the standard was issued but before the acquisition has been reflected in financial statements. We adopted the provisions of ASU 2017-01 in the first quarter of 2017. The adoption of ASU 2017-01 did not have a material effect on our consolidated financial statements. Our acquisitions in 2017 were accounted for as asset acquisitions. On June 7, 2017, FASB members unanimously confirmed their intention to approve the proposed changes to the hedge accounting guidance in ASC 815. The final guidance is expected to be issued in the third quarter of 2017 with a mandatory effective date for public business entities’ fiscal years beginning after December 15, 2018. Early adoption is available for interim periods immediately upon issuance of the final guidance. Key provisions in the updated guidance include 1) changing the measurement and presentation of ineffectiveness in the financial statements so that the entire change in the fair value of the hedging instrument (including amounts excluded from the assessment of effectiveness) will be presented in the same income statement line item in which the earnings effect of the hedged item is presented, 2) changing effectiveness testing to allow the assessment of effectiveness on a qualitative basis in certain circumstances, and 3) adjustments to fair value hedging to allow new strategies.
