On January 1, 2019, we adopted Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842), as amended ("ASU 2016-02"). The selected financial data above for 2019 reflects the adoption of ASU 2016-02. At January 1, 2019, we recognized the cumulative effect of initially applying ASU 2016-02 as an adjustment to the opening balance of (Distributions in excess of earnings) Earnings in excess of distributions, resulting in an increase of approximately $5.8 million to stockholders' equity.
(2)
On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). The selected financial data above for 2018 reflects the adoption of ASU 2014-09. At January 1, 2018, we recognized the cumulative effect of initially applying ASU 2014-09 as an adjustment to the opening balance of (Distributions in excess of earnings) Earnings in excess of distributions, resulting in a decrease of approximately $30.2 million to stockholders' equity.

The selected financial data above for 2018 includes the results of IODC from January 10, 2018.

In June 2019, we received a notification of assessment from tax and customs authorities in the Netherlands related to a value-added tax (“VAT”) liability of approximately 16.8 million Euros primarily related to the years ending December 31, 2018 and 2017, as described more fully in Note 2.y. to Notes to Consolidated Financial Statements included in this Annual Report. Based on our estimate of the amount of loss related to this matter that is both probable and estimable, we have restated the following: (i) selling, general and administrative expenses and interest expense were increased by approximately $11.0 million and $0.4 million, respectively, and the provision for income taxes was decreased by approximately $2.0 million for the year ended December 31, 2018 and (ii) selling, general and administrative expenses and interest expense were increased by approximately $16.6 million and $0.1 million, respectively, and the provision for income taxes was decreased by approximately $3.0 million for the year ended December 31, 2017.

Beginning in the fourth quarter of 2019, we present Significant Acquisition Costs (as defined in Note 2.x. to Notes to Consolidated Financial Statements included in this Annual Report) as a separate line on our Consolidated Statements of Operations. Previously, these costs were included within Cost of sales (excluding depreciation and amortization) and Selling, general and administrative expense. All prior periods are now presented to conform to this presentation. This change in presentation resulted in a decrease in Cost of sales (excluding depreciation and amortization) of approximately $7.6 million, $20.5 million, $12.0 million and $0.0 million for the years ended December 31, 2018, 2017, 2016 and 2015, respectively, and a decrease to Selling, general and administrative expense of approximately $43.0 million, $64.4 million, $120.0 million and $47.0 million for the years ended December 31, 2018, 2017, 2016 and 2015, respectively. See Note 2.x. to Notes to Consolidated Financial Statements included in this Annual Report for additional information on this change in presentation.

Beginning in 2019, we present gains on sale of real estate as a component of operating income in the line item (Gain) loss on disposal/write-down of property, plant and equipment, net in our Consolidated Statements of Operations. Such amounts are presented gross of tax with any tax impact presented within Provision (benefit) for income taxes. All prior periods are now presented to conform to this presentation. Previously, we classified gains on sale of real estate, net of tax, as a separate line on our Consolidated Statements of Operations and excluded such amounts from our reported operating income. We presented such amounts net of tax as these gains were presented below the Provision (benefit) for income taxes in our Consolidated Statements of Operations. This change in presentation resulted in an increase in (Gain) loss on disposal/write-down of property, plant and equipment, net of approximately $63.8 million, $1.6 million, $2.3 million and $1.1 million for the years ended December 31, 2018, 2017, 2016 and 2015, respectively, and an increase in Provision (benefit) for income taxes of approximately $8.5 million, $0.0 million, $0.1 million and $0.2 million for the years ended December 31, 2018, 2017, 2016 and 2015, respectively. See Note 2.x. to Notes to Consolidated Financial Statements included in this Annual Report for additional information on this change in presentation.
