| THREE MONTHS ENDED SEPTEMBER 30, |  | NINE MONTHS ENDED SEPTEMBER 30,
| 2022(1) |  | 2021 |  | 2022(1) |  | 2021(2)

(1) The gain for the nine months ended September 30, 2022 primarily consists of gains of approximately $66,000 associated with sale and sale-leaseback transactions, of which (i) approximately $17,000 relates to sale-leaseback transactions of two facilities in the United States and one in Canada during the third quarter of 2022 and (ii) approximately $49,000 relates to sale and sale-leaseback transactions of 11 facilities and parcels of land in the United States during the second quarter of 2022. (2) The gain for the nine months ended September 30, 2021 primarily consists of gains of approximately $127,400 associated with sale-leaseback transactions of five facilities in the United Kingdom during the second quarter of 2021. (3) The gains recognized during both 2022 and 2021 are the result of our program to monetize a small portion of our industrial assets through sale and sale-leaseback transactions. 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 Current Report.
Schedule of Other (Income) Expense, Net | Other (income) expense, net for the three and nine months ended September 30, 2022 and 2021 consists of the following:
|  | THREE MONTHS ENDED SEPTEMBER 30, |  | NINE MONTHS ENDED SEPTEMBER 30,
DESCRIPTION |  | 2022 |  | 2021 |  | 2022 |  | 2021
Foreign currency transaction (gains) losses, net(1) |  | $ | (58,519) |  |  | $ | (23,200) |  |  | $ | (126,759) |  |  | $ | (16,157) |

Other, net(2)(3) |  | 5,649 |  |  | 4,699 |  |  | 87,902 |  |  | (183,861) |
Other (Income) Expense, Net |  | $ | (52,870) |  |  | $ | (18,501) |  |  | $ | (38,186) |  |  | $ | (200,018) |
(1)We recognized net foreign currency transaction gains of $58,519 and $126,759 for the three and nine months ended September 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 the subsequent remeasurement of the retained investment to a 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 nine months ended September 30, 2021 is primarily comprised of (a) a gain of approximately $180,600 associated with our IPM Divestment (as defined and discussed in Note 4 to Notes to Consolidated Financial Statements included in our Current 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.
Schedule of Income Taxes | Our effective tax rates for the three and nine months ended September 30, 2022 and 2021 are as follows:
| THREE MONTHS ENDED SEPTEMBER 30, |  | NINE MONTHS ENDED SEPTEMBER 30,
| 2022(1) |  | 2021(2) |  | 2022(1) |  | 2021(2)
Effective Tax Rate | 11.0 | % |  | 29.1 | % |  | 10.7 | % |  | 28.1 | %
(1)The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and nine months ended September 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 (income) expense, 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 nine months ended September 30, 2021 were the impacts of differences in the tax rates at which our foreign earnings are subject, partially offset by the benefits derived from the dividends paid deduction. The costs associated with Project Summit (as defined in Note 11) are more heavily weighted to our United States qualified REIT subsidiaries ("QRSs"), and, therefore, provide no tax benefit. Additionally, the nine months ended September 30, 2021 reflects a discrete tax expense of approximately $12,000 primarily resulting from a tax law change in the United Kingdom.
