Sale of Data Centers and Colocation Business

On May 1, 2017, we sold our data centers and colocation business to a consortium led by BC Partners, Inc. and Medina Capital in exchange for cash and a minority stake in the limited partnership that owns the consortium's newly-formed global secure infrastructure company, Cyxtera Technologies ("Cyxtera").

At the closing of this sale, we received pre-tax cash proceeds of $1.8 billion, and we valued our minority stake at $150 million, which was based upon the total amount of equity contributions to the limited partnership on the date made. Due to the sale and related restructuring actions we have taken regarding certain subsidiaries involved in the data centers and colocation business, we have estimated a cumulative current tax impact relating to the sale totaling $65 million, $18 million of which was accrued in 2016 and $47 million of which was accrued in 2017.

In connection with our sale of the data centers and colocation business to Cyxtera, we agreed to lease back from Cyxtera a portion of the data center space to provide data hosting services to our customers. Because we have continuing involvement in the business through our minority stake in Cyxtera's parent, we did not meet the requirements for a sale-leaseback transaction as described in ASC 840-40, Leases - Sale-Leaseback Transactions. Under the failed-sale-leaseback accounting model, we were deemed under GAAP to still own certain real estate assets sold to Cyxtera, which we continued to reflect on our consolidated balance sheet and depreciate over the assets' remaining useful life. We also treated a certain amount of the pre-tax cash proceeds from the sale of the assets as though it were the result of a financing obligation on our consolidated balance sheet, and our consolidated results of operations included imputed revenue associated with the portion of the real estate assets that we did not lease back and imputed interest expense on the financing obligation. A portion of the rent payments under our leaseback arrangement with Cyxtera were recognized as a reduction of the financing obligation, resulting in lower recognized rent expense than the amounts actually paid each period.

The following table reflects the assets sold to and the liabilities assumed by Cyxtera on May 1, 2017, including the impact of failed-sale-leaseback:



	Dollars in millions
Goodwill	$	1,142
Property, plant and equipment	1,051
Other intangible assets	249
Other assets	66
Less assets not removed as a result of the failed-sale-leaseback	(526		)
Total net amount of assets derecognized	$	1,982

Capital lease obligations	$	294
Other liabilities	274
Less imputed financing obligations from the failed-sale-leaseback	(628		)
Total net imputed liabilities recognized	$	(60	)

In addition, the failed-sale-leaseback accounting treatment had the following effects on our consolidated results of operations for the years ended December 31, 2018 and 2017:



	Positive (Negative) Impact to Net Income
	December 31,
	2018			2017
	(Dollars in millions)
Increase in revenue	$	74		49
Decrease in cost of sales	22			15
Increase in loss on sale of business included in selling, general and administrative expense	—			(102	)
Increase in depreciation expense (one-time)	—			(44	)
Increase in depreciation expense (ongoing)	(69		)	(47	)
Increase in interest expense	(55		)	(39	)
Decrease in income tax expense	7			65
Decrease in net income	$	(21	)	(103	)

After factoring in the costs to sell the data centers and colocation business, excluding the impact from the failed-sale-leaseback accounting treatment, the sale resulted in a $20 million gain as a result of the aggregate value of the proceeds we received exceeding the carrying value of the assets sold and liabilities assumed. Based on the fair market values of the failed-sale-leaseback assets, the failed-sale-leaseback accounting treatment resulted in a loss of $102 million as a result of the requirement to treat a certain amount of the pre-tax cash proceeds from the sale of the assets as though it were the result of a financing obligation. The combined net loss of $82 million was included in selling, general and administrative expenses in our consolidated statement of operations for the year ended December 31, 2017. The sale also resulted in a significant capital loss carryforward, which was entirely offset by a valuation allowance due to our determination that we are not likely to be able to utilize this carryforward prior to its expiration.

We evaluated our minority stake in the limited partnership and determined that we were not the primary beneficiary of the entity. As a result, we classified our $150 million investment in the limited partnership in other assets on our consolidated balance sheet as of December 31, 2018 and 2017. In addition to our investment, we have a $3 million payable to Cyxtera, classified in other accrued liabilities on our consolidated balance sheet as of December 31, 2018. We had a receivable for $10 million and $49 million, classified in other current assets on our consolidated balance sheet as of December 31, 2018 and 2017, respectively as a result of amounts charged for the lease of data center space. We will continue to have an ongoing obligation to Cyxtera related to our lease of data center space from them. During the year ended December 31, 2018, we paid rent to Cyxtera totaling $132 million. From May 1, 2017 through December 31, 2017, we paid rent to Cyxtera totaling $80 million.

Effective November 3, 2016, which is the date we entered into the agreement to sell our data centers and colocation business, we ceased recording depreciation of the property, plant and equipment to be sold and amortization of the business's intangible assets in accordance with applicable accounting rules. Otherwise, we estimate that we would have recorded additional depreciation and amortization expense of $67 million from January 1, 2017 through May 1, 2017.

Upon adopting ASU 2016-02, accounting for the failed sale leaseback will no longer be applicable based on our facts and circumstances, and the real estate assets and corresponding financing obligation will be derecognized from our consolidated financial statements. Please see "Leases" (ASU 2016-02) in Note 1— Background and Summary of Significant Accounting Policies for additional information on the impact the new lease standard will have on the accounting for the failed-sale-leaseback.
