Basis of Presentation

Our interim consolidated financial statements have been prepared, without audit, in accordance with the instructions to Form 10-Q and, therefore, do not necessarily include all information and footnotes necessary for a fair statement of our consolidated financial position, results of operations, and cash flows in accordance with accounting principles generally accepted in the U.S., or GAAP.

In the opinion of management, the unaudited financial information for the interim periods presented in this Report reflects all normal and recurring adjustments necessary for a fair statement of financial position, results of operations, and cash flows. Our interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes for the year ended December 31, 2013, which are included in the 2013 Annual Report, as certain disclosures that would substantially duplicate those contained in the audited consolidated financial statements have not been included in this Report. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our consolidated financial statements and the accompanying notes. Actual results could differ from those estimates.

The unaudited consolidated financial statements included in this Report have been retrospectively adjusted to reflect the disposition (or planned disposition) of certain properties as discontinued operations for all periods presented.

Basis of Consolidation

Our consolidated financial statements reflect all of our accounts, including those of our controlled subsidiaries and our tenancy-in-common interests as described below. The portion of equity in a consolidated subsidiary that is not attributable, directly or indirectly, to us is presented as noncontrolling interests. All significant intercompany accounts and transactions have been eliminated.

We have investments in tenancy-in-common interests in various domestic and international properties. Consolidation of these investments is not required as such interests do not qualify as VIEs and do not meet the control requirement required for consolidation. Accordingly, we account for these investments using the equity method of accounting. We use the equity method of accounting because the shared decision-making involved in a tenancy-in-common interest investment provides us with significant influence on the operating and financial decisions of these investments.

Additionally, we own interests in single-tenant net-leased properties leased to companies through noncontrolling interests in partnerships and limited liability companies that we do not control but over which we exercise significant influence. We account for these investments under the equity method of accounting. At times, the carrying value of our equity investments may fall below zero for certain investments. We intend to fund our share of the jointly-owned investments’ future operating deficits should the need arise. However, we have no legal obligation to pay for any of the liabilities of such investments nor do we have any legal obligation to fund operating deficits.

We apply accounting guidance for consolidation of VIEs to certain entities in which the equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. Fixed price purchase and renewal options within a lease as well as certain decision-making rights within a loan can cause us to consider an entity a VIE.

Recent Accounting Requirement

The following Accounting Standards Update, or ASU, promulgated by the Financial Accounting Standards Board, or FASB, is applicable to us:

ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) — ASU 2014-08 changes the requirements for reporting discontinued operations. A discontinued operation may include a component of an entity or a group of components of an entity, or a business. Under this new guidance, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a “strategic shift that has or will have a major effect on an entity’s operations and financial results.” The new guidance also requires disclosures including pre-tax profit or loss and significant gains or losses arising from dispositions that represent an “individually significant component of an entity,” but do not meet the criteria to be reported as discontinued operations under ASU 2014-08. In the ordinary course of business, we sell properties, which, under prior accounting guidance, we generally reported as discontinued operations; however, under ASU 2014-08 such property dispositions typically would not meet the criteria to be reported as discontinued operations. We elected to early adopt ASU 2014-08 prospectively for all dispositions after December 31, 2013. Consequently, individually significant properties that are sold or classified as held-for-sale during 2014 will not be reclassified to discontinued operations in the Consolidated statements of income, but will be disclosed in the Notes to consolidated financial statements. By contrast, and as required by the new guidance, the consolidated statements of income for the prior year periods reflect all dispositions through December 31, 2013 as discontinued operations, which were deemed discontinued operations under the prior accounting guidance. This ASU did not have a significant impact on our financial position or results of operations for any of the periods presented.
