ASU 2016-09 is effective for public business entities for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period, with early adoption permitted.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We adopted ASU 2016-09 as of January 1, 2017 and elected to account for forfeitures as they occur, rather than to account for them based on an estimate of expected forfeitures. This election was adopted using a modified retrospective transition method, with a cumulative effect adjustment to retained earnings. The related financial statement impact of this adjustment is not material. Depending on several factors, such as the market price of our common stock, employee stock option exercise behavior, and corporate income tax rates, the excess tax benefits associated with the exercise of stock options and the vesting and delivery of RSAs, RSUs, and PSUs, could generate a significant income tax benefit in a particular interim period, potentially creating volatility in Net income attributable to W. P. Carey and basic and diluted earnings per share between interim periods. Under the former accounting guidance, windfall tax benefits related to stock-based compensation were recognized within Additional paid-in capital in our consolidated financial statements. Under ASU 2016-09, these amounts are reflected as a reduction to Provision for income taxes. For reference, windfall tax benefits related to stock-based compensation recorded in Additional paid-in capital for the years ended December 31, 2016 and 2015 were </font><font style="font-family:inherit;font-size:10pt;">$6.7 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$12.5 million</font><font style="font-family:inherit;font-size:10pt;">, respectively. Windfall tax benefits related to stock-based compensation recorded as a deferred tax benefit for the year ended December 31, 2017 was </font><font style="font-family:inherit;font-size:10pt;">$4.6 million</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In October 2016, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">ASU 2016-17, Consolidation (Topic 810): Interests Held through Related Parties That Are under Common Control.</font><font style="font-family:inherit;font-size:10pt;"> ASU 2016-17 changes how a reporting entity that is a decision maker should consider indirect interests in a VIE held through an entity under common control. If a decision maker must evaluate whether it is the primary beneficiary of a VIE, it will only need to consider its proportionate indirect interest in the VIE held through a common control party. ASU 2016-17 amends ASU 2015-02, which we adopted on January 1, 2016, and which currently directs the decision maker to treat the common control party’s interest in the VIE as if the decision maker held the interest itself. ASU 2016-17 is effective for public business entities in fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. We adopted ASU 2016-17 as of January 1, 2017 on a prospective basis. The adoption of this standard did not have a material impact on our consolidated financial statements.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2017, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business</font><font style="font-family:inherit;font-size:10pt;">. ASU 2017-01 intends to clarify the definition of a business with the objective of adding guidance to assist entities with 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. While an integrated set of assets and activities, collectively referred to as a “set,” that is a business usually has outputs, outputs are not required to be present. ASU 2017-01 provides a screen to determine when a set is not a business. The screen requires that when substantially all of 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 will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. We elected to early adopt ASU 2017-01 on January 1, 2017 on a prospective basis. While our acquisitions have historically been classified as either business combinations or asset acquisitions, certain acquisitions that were classified as business combinations by us likely would have been considered asset acquisitions under the new standard. As a result, all transaction costs incurred during the year ended December 31, 2017 were capitalized since our acquisitions during the year were classified as asset acquisitions. Most of our future acquisitions are likely to be classified as asset acquisitions under this new standard. In addition, goodwill that was previously allocated to businesses that were sold or held for sale will no longer be allocated and written off upon sale if future sales were deemed to be sales of assets and not businesses.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2017, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">ASU 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment</font><font style="font-family:inherit;font-size:10pt;">. ASU 2017-04 removes step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. ASU 2017-04 will be effective for public business entities in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years in which a goodwill impairment test is performed, with early adoption permitted. We adopted ASU 2017-04 as of April 1, 2017 on a prospective basis. The adoption of this standard did not have a material impact on our consolidated financial statements.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Pronouncements to be Adopted after </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">December 31, 2017</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2014, the FASB issued</font><font style="font-family:inherit;font-size:10pt;font-style:italic;"> ASU 2014-09</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers (Topic 606).</font><font style="font-family:inherit;font-size:10pt;"> ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 does not apply to our lease revenues, which constitute a majority of our revenues, but will primarily apply to revenues generated from our operating properties and our Investment Management business. We adopted this guidance for our interim and annual periods beginning January 1, 2018 using the modified retrospective method. We performed a comprehensive evaluation of the impact of the new standard across our revenue streams, and determined that the timing of revenue recognition and its classification in our consolidated financial statements will remain substantially unchanged.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">ASU 2016-02, Leases (Topic 842). </font><font style="font-family:inherit;font-size:10pt;">ASU 2016-02 outlines a new model for accounting by lessees, whereby their rights and obligations under substantially all leases, existing and new, would be capitalized and recorded on the balance sheet. For lessors, however, the accounting remains largely unchanged from the current model, with the distinction between operating and financing leases retained, but updated to align with certain changes to the lessee model and the new revenue recognition standard. The new standard also replaces existing sale-leaseback guidance with a new model applicable to both lessees and lessors. In addition, it also requires lessors to record gross revenues and expenses associated with activities that do not transfer services to the lessee (such as real estate taxes and insurance). Additionally, the new standard requires extensive quantitative and qualitative disclosures. Early application will be permitted for all entities. The new standard must be adopted using a modified retrospective transition of the new guidance and provides for certain practical expedients. Transition will require application of the new model at the beginning of the earliest comparative period presented. We will adopt this guidance for our interim and annual periods beginning January 1, 2019. The ASU is expected to impact our consolidated financial statements as we have certain operating office and land lease arrangements for which we are the lessee. We are evaluating the impact of the new standard and have not yet determined if it will have a material impact on our business or our consolidated financial statements.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">ASU 2016-13, Financial Instruments — Credit Losses. </font><font style="font-family:inherit;font-size:10pt;">ASU 2016-13 introduces a new model for estimating credit losses based on current expected credit losses for certain types of financial instruments, including loans receivable, held-to-maturity debt securities, and net investments in direct financing leases, amongst other financial instruments. ASU 2016-13 also modifies the impairment model for available-for-sale debt securities and expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for losses. ASU 2016-13 will be effective for public business entities in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early application of the guidance permitted.

ASU 2016-18 intends to reduce diversity in practice for the classification and presentation of changes in restricted cash on the statement of cash flows. ASU 2016-18 requires 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.

The amendments define the term “in substance nonfinancial asset,” in part, as a financial asset promised to a counterparty in a contract if substantially all of the fair value of the assets (recognized and unrecognized) that are promised to the counterparty in the contract is concentrated in nonfinancial assets. If substantially all of the fair value of the assets that are promised to the counterparty in a contract is concentrated in nonfinancial assets, then all of the financial assets promised to the counterparty are in substance nonfinancial assets within the scope of Subtopic 610-20. This amendment also clarifies that nonfinancial assets within the scope of Subtopic 610-20 may include nonfinancial assets transferred within a legal entity to a counterparty. For example, a parent company may transfer control of nonfinancial assets by transferring ownership interests in a consolidated subsidiary. ASU 2017-05 is effective for periods beginning after December 15, 2017, with early application permitted for fiscal years beginning after December 15, 2016. We adopted this guidance for our interim and annual periods beginning January 1, 2018. The adoption of ASU 2017-05 is not expected to have a significant impact on our consolidated financial statements.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2017, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">ASU 2017-09, Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting</font><font style="font-family:inherit;font-size:10pt;">. ASU 2017-09 clarifies when to account for a change to the terms and conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, vesting conditions, or classification of the award (as equity or liability) changes as a result of the change in terms or conditions. ASU 2017-09 will be effective in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted.

ASU 2017-12 will make more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess hedge effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. ASU 2017-12 will be effective in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We are in the process of evaluating the impact of adopting ASU 2017-12 on our consolidated financial statements, and expect to adopt the standard for the fiscal year beginning January 1, 2019.</font></div></div>
