CMS ENERGY CORPORATION CONSUMERS ENERGY COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) In connection with the sale of CMS Energy’s Argentine and Michigan assets to Lucid Energy in March 2007, CMS Energy entered into agreements that granted MEI, an affiliate of Lucid Energy, the right to any proceeds from an assignment of the ICSID award associated with TGN.
The agreements also granted MEI an option to purchase CMS Gas Transmission’s ownership interests in TGN, and the rights to any proceeds CMS Enterprises will receive if it sells its stock interest in CMS Generation San Nicolas Company.
In June 2008, CMS Energy executed an agreement with MEI and a third party to assign the ICSID award and to sell its interests in TGN directly to the third party.
In accordance with the agreements executed in March 2007, the proceeds from the assignment of the ICSID award and the sale of TGN were passed on to MEI and CMS Energy recognized an $8 million gain on the assignment of the ICSID award in Gain on asset sales, net on CMS Energy’s Consolidated Statements of Income (Loss).
CMS Energy also recognized a $197 million cumulative net foreign currency translation loss related to TGN, which had been deferred as a Foreign currency translation component of stockholders’ equity.
This charge was fully offset by the elimination of a $197 million Argentine currency impairment reserve on CMS Energy’s Consolidated Balance Sheets, created when it impaired its investment in TGN in March 2007.
For additional details, see “Impairment Charges” within this Note.
As of December 31, 2009, $7 million remained as a deferred credit on CMS Energy’s Consolidated Balance Sheets related to MEI’s right to proceeds that CMS Enterprises will receive if it sells its stock interest in CMS Generation San Nicolas Company.

Operating Activities Presented in the following table are specific components of net cash provided by operating activities for 2017, 2016, and 2015:
## Table 1 ##
Non-cash transactions comprise depreciation and amortization, changes in deferred income taxes, bad debt expense, and other non-cash operating activities and reconciling adjustments.2 Core working capital comprises accounts receivable, notes receivable, accrued revenue, inventories, accounts payable, and accrued rate refunds.
For 2017, net cash provided by operating activities at CMS Energy increased $76 million compared with 2016 and net cash provided by operating activities at Consumers increased $34 million compared with 2016.
These increases were due primarily to higher net income, net of non-cash transactions, which included the impacts of the TCJA.
Also contributing to the increases were lower postretirement benefit contributions and higher collections from customers.
These changes were offset partially by gas purchased at higher prices and increased spending on environmental remediation activities.
The increase at Consumers also reflected lower tax payments to CMS Energy.
For 2016, net cash provided by operating activities at CMS Energy decreased $11 million compared with 2015 and net cash provided by operating activities at Consumers decreased $113 million compared with 2015.
These changes were due primarily to lower customer collections, reflecting lower gas prices and sales volumes, offset partially by lower postretirement benefits contributions and higher net income.
At Consumers, higher income tax payments to CMS Energy also contributed to the decrease in net cash provided by operating activities in 2016.
DEVON ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued) Asset Divestitures In conjunction with the asset divestitures in 2013 and 2014, Devon removed $26 million and $706 million of goodwill, respectively, which were allocated to these assets.
Impairment Devon’s Canadian goodwill was originally recognized in 2001 as a result of a business combination consisting almost entirely of conventional gas assets that Devon no longer owns.
As a result of performing the goodwill impairment test described in Note 1, Devon concluded the implied fair value of its Canadian goodwill was zero as of December 31, 2014.
This conclusion was largely based on the significant decline in benchmark oil prices, particularly after OPEC’s decision not to reduce its production targets that was announced in late November 2014.
Consequently, in the fourth quarter of 2014, Devon wrote off its remaining Canadian goodwill and recognized a $1.9 billion impairment.
Other Intangible Assets As of December 31, 2014, intangible assets associated with customer relationships had a gross carrying amount of $569 million and $36 million of accumulated amortization.
The weighted-average amortization period for the customer relationships is 13.7 years.
Amortization expense for intangibles was approximately $36 million for the year ended December 31, 2014.
Other intangible assets are reported in other long-term assets in the accompanying consolidated balance sheets.
The following table summarizes the estimated aggregate amortization expense for the next five years.
