Our reporting units as of December 31, 2021 are described in detail in Note 2.k. to Notes to Consolidated Financial Statements included in our Annual Report. During the second quarter of 2022, as a result of the realignment of our global managerial structure, we reassessed the composition of our reportable segments (see Note 9 for a description and definition of our reportable segments) as well as our reporting units.


We note the following changes to our reporting units as a result of the reassessment described above:
•our former Europe RIM reporting unit is now managed as two separate reporting units: (1) our Middle East, North Africa and Turkey ("MENAT") businesses will comprise our "MENAT RIM" reporting unit and (2) our other businesses in Europe and South Africa ("ESA") will comprise our “ESA RIM” reporting unit; •our former ANZ RIM and Asia RIM reporting units are now managed as one "APAC RIM" reporting unit; and •our asset lifecycle management ("ALM") business, which includes our legacy secure IT asset disposition business (which was primarily previously included in our North America RIM reporting unit) and the business acquired through our acquisition of Intercept Parent, Inc. ("ITRenew"), will comprise our newly formed "ALM" reporting unit.

There were no changes to our Latin America RIM, Global Data Center and Fine Arts reporting units. We have reassigned goodwill associated with the reporting units impacted by the reorganization on a relative fair value basis, where appropriate. The fair value of each of our new reporting units was determined based on the application of a combined weighted average approach of preliminary fair value multiples of revenue and earnings and discounted cash flow techniques. These fair values represent our best estimate and preliminary assessment of goodwill allocations to each of the new reporting units on a relative fair value basis. We have completed an interim goodwill impairment analysis before and after the reporting unit changes, and we have concluded that the goodwill associated with each of our reporting units was not impaired.

Our Global Data Center Business features storage rental provided to customers at contractually specified rates over a fixed contractual period, which are accounted for in accordance with Accounting Standards Codification ("ASC") No. 842 ("ASC 842"), Leases, as amended. Storage rental revenue, including revenue associated with power and connectivity, associated with our Global Data Center Business for the three and six months ended June 30, 2022 and 2021 are as follows:

Our stock-based compensation expense includes the cost of stock options, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan ("ESPP") (together, the "Employee Stock-Based Awards").

•Upon an award recipient's retirement on or after attaining age 55 with at least five years of service, if the sum of (i) the award recipient’s age at retirement and (ii) the award recipient’s years of service with us totals at least 65, the award recipient is entitled to continued vesting of any outstanding Employee Stock-Based Awards, provided that their retirement occurs on or after a minimum of six months from the grant date (the "Retirement Criteria").

•Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the Retirement Criteria on or before the date of grant, or will meet the Retirement Criteria before the six month anniversary in the year of the grant, will be expensed over six months from the date of grant and (ii) grants of Employee Stock-Based Awards to employees who will meet the Retirement Criteria during the award’s normal vesting period will be expensed between the date of grant and the date upon which the award recipient meets the Retirement Criteria.

•Stock options and RSUs granted to award recipients who meet the Retirement Criteria will be delivered to the award recipient based upon the original vesting schedule. If an award recipient retires and has met the Retirement Criteria, stock options will remain exercisable until the original expiration date of the stock options. PUs granted to award recipients who meet the Retirement Criteria will be delivered in accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions.

Acquisition and integration costs represent operating expenditures directly associated with the closing and integration activities of our business acquisitions that have closed, or are highly probable of closing, and include (i) advisory, legal and professional fees to complete business acquisitions and (ii) costs to integrate acquired businesses into our existing operations, including move, severance, facility upgrade and system integration costs (collectively, "Acquisition and Integration Costs"). Acquisition and Integration Costs do not include costs associated with the formation of joint ventures or costs associated with the acquisition of customer relationships. Total Acquisition and Integration Costs is $16,878 and $32,539 for the three and six months ended June 30, 2022, respectively, and $2,277 for both the three and six months ended June 30, 2021.

(1) The gains for the three and six months ended June 30, 2022 primarily consisted of gains of approximately $49,000 associated with the sale and sale-leaseback transactions of 11 facilities and parcels of land in the United States, as part of our program to monetize a portion of our industrial assets. The terms for these leases are consistent with the terms of our lease portfolio, which are disclosed in detail in Note 2.i. to Notes to Consolidated Financial Statements included in our Annual Report.

(2) The gains for the three and six months ended June 30, 2021 primarily consisted of gains of approximately $127,400 associated with the sale-leaseback transactions of five facilities in the United Kingdom, as part of our program to monetize a small portion of our industrial assets. The terms for these leases are consistent with the terms of our lease portfolio, which are disclosed in detail in Note 2.i. to Notes to Consolidated Financial Statements included in our Annual Report.

(1)We recognized net foreign currency transaction gains of $55,039 and $68,240 for the three and six months ended June 30, 2022, respectively. These gains primarily consist of the impact of changes in the exchange rate of the Euro and the British pound sterling against the United States dollar on our intercompany balances with and between certain of our subsidiaries.

(2)On March 24, 2022, as a result of our loss of control, we deconsolidated the businesses included in the acquisition of OSG Records Management (Europe) Limited, excluding Ukraine. We recognized a loss of approximately $105,800 associated with the deconsolidation to Other expense (income), net in the first quarter of 2022 representing the difference between the net asset value prior to the deconsolidation and subsequent remeasurement of the retained investment to fair value of zero. We have concluded that the deconsolidation does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as it does not represent a strategic shift that will have a major effect on our operations and financial results. The loss was partially offset by a gain recorded in the first quarter of 2022 of approximately $35,800 associated with the Clutter Transaction (as defined in Note 4).

(3)Other, net for the three and six months ended June 30, 2021 is primarily comprised of (a) a gain of approximately $181,200 associated with our IPM Divestment (as defined and discussed in Note 4 to Notes to Consolidated Financial Statements included in our Annual Report) and (b) a gain of approximately $20,300 associated with the loss of control and related deconsolidation, as of May 18, 2021 of one of our wholly owned Netherlands subsidiaries, for which we had value-added tax liability exposure that was recorded in 2019.

(1)The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and six months ended June 30, 2022 were the benefits derived from the dividends paid deduction and the differences in the tax rates to which our foreign earnings are subject. In addition, there were gains and losses recorded in Other expense (income), net and Gain (loss) on disposal/write-down of property, plant and equipment net, during the period for which there was an insignificant tax impact. During the first quarter of 2022, there was also a release of valuation allowances on deferred tax assets of our U.S. taxable REIT subsidiaries ("TRS") of approximately $9,900 as a result of the ITRenew Transaction.

(2)The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and six months ended June 30, 2021 were the impacts of differences in the tax rates at which our foreign earnings are subject and a discrete tax expense of approximately $12,000 primarily resulting from a tax law change in the United Kingdom, partially offset by the benefits derived from the dividends paid deduction.
