VARIABLE INTEREST ENTITIES
Consolidated Variable Interest Entities ("VIEs")
The Company holds a variable interest in the following joint ventures or entities for which it is the primary beneficiary.

Asia Pacific joint ventures
The Company has variable interests in three joint ventures that own and operate manufacturing and logistics facilities, which produce chemicals and provide services in Asia Pacific. The Company's variable interests in these joint ventures relate to arrangements between the joint ventures and the Company, involving the majority of the output on take-or-pay terms with pricing ensuring a guaranteed return to the joint ventures.

Polishing materials joint venture
The Company has variable interests in a joint venture that manufactures products in Japan for the semiconductor industry. Each joint venture partner holds several equivalent variable interests, with the exception of a royalty agreement held exclusively between the joint venture and the Company. In addition, the entire output of the joint venture is sold to the Company for resale to third-party customers.

Ethylene storage joint venture
The Company has variable interests in a joint venture that provides ethylene storage in Alberta, Canada. The Company's variable interests relate to arrangements involving a majority of the joint venture's storage capacity on take-or-pay terms with pricing ensuring a guaranteed return to the joint venture; and favorably priced leases provided to the joint venture. The Company provides the joint venture with operation and maintenance services and utilities.

Ethanol production and cogeneration in Brazil
The Company held a variable interest in a joint venture located in Brazil that produces ethanol from sugarcane. In August 2015, the partner exercised an equity option which required Dow to purchase their equity interest. On March 31, 2016, the partner's equity investment transferred to the Company. On July 11, 2016, the Company paid $202 million to the former partner, which was classified as "Purchases of noncontrolling interests" in the consolidated statements of cash flows. This former joint venture is now 100 percent owned by the Company. The Company continues to hold variable interests in a related entity that owns a cogeneration facility. The Company's variable interests are the result of a tolling arrangement where it provides fuel to the entity and purchases a majority of the cogeneration facility’s output on terms that ensure a return to the entity’s equity holders.

Chlor-alkali manufacturing joint venture
The Company previously held an equity interest in a joint venture that owns and operates a membrane chlor-alkali manufacturing facility. The Company’s variable interests in this joint venture related to equity options between the partners and a cost-plus off-take arrangement between the joint venture and the Company, involving proportional purchase commitments on take-or-pay terms and ensuring a guaranteed return to the joint venture. In the second quarter of 2015, Mitsui (a 50 percent equity owner in this joint venture), provided notice of its intention to transfer its equity interest to Dow as part of the Transaction with Olin. On October 5, 2015, the Company purchased Mitsui's equity interest in the membrane chlor-alkali joint venture for $133 million, which resulted in a loss of $25 million included in "Sundry income (expense) - net" in the consolidated statements of income and included as a component of the pretax gain on the Transaction. See Note 7 for additional information on this Transaction.

U.S. Seed production joint venture
The Company previously held a 49 percent equity interest in a joint venture that managed the growth, harvest and conditioning of soybean seed and grain, corn and wheat in the United States. The Company's variable interest in this joint venture related to an equity option between the partners. Terms of the equity option required the Company to purchase the partner's equity investment at a price based on a specified formula, after a specified period of time, and satisfaction of certain conditions, if the partner elected to sell its equity investment. On August 10, 2015, the equity option was determined to be exercisable and the partner provided notice to the Company of its intent to exercise the equity option, which resulted in an after-tax loss of $22 million, included in "Net income attributable to noncontrolling interests" in the consolidated statements of income. The Company purchased the partner's equity investment on September 18, 2015, which resulted in the joint venture becoming a wholly owned subsidiary of Dow. Subsequent to the purchase of the partner's equity investment, the Company sold its entire ownership interest in the subsidiary to a third party and recognized a pretax gain of $44 million on the sale in the third quarter of 2015, included in "Sundry income (expense) - net" in the consolidated statements of income.

Assets and Liabilities of Consolidated VIEs
The Company's consolidated financial statements include the assets, liabilities and results of operations of VIEs for which the Company is the primary beneficiary. The other equity holders’ interests are reflected in "Net income attributable to noncontrolling interests" in the consolidated statements of income and "Noncontrolling interests" in the consolidated balance sheets.

The following table summarizes the carrying amounts of these entities’ assets and liabilities included in the Company’s consolidated balance sheets at December 31, 2017 and 2016:

In addition, the Company holds a variable interest in an entity created to monetize accounts receivable of select European entities. The Company is the primary beneficiary of this entity as a result of holding subordinated notes while maintaining servicing responsibilities for the accounts receivable. The carrying amounts of assets and liabilities included in the Company’s consolidated balance sheets pertaining to this entity were current assets of $671 million (zero restricted) at December 31, 2017 ($477 million, zero restricted, at December 31, 2016) and current liabilities of less than $1 million (zero nonrecourse) at December 31, 2017 (less than $1 million, zero nonrecourse, at December 31, 2016).

Amounts presented in the consolidated balance sheets and the table above as restricted assets or nonrecourse obligations relating to consolidated VIEs at December 31, 2017 and 2016 are adjusted for intercompany eliminations and parental guarantees.

Nonconsolidated VIEs
The Company holds a variable interest in the following entities for which Dow is not the primary beneficiary.

Polysilicon joint venture
As a result of the DCC Transaction, the Company holds variable interests in Hemlock Semiconductor L.L.C. The variable interests relate to an equity interest held by the Company and arrangements between the Company and the joint venture to provide services. The Company is not the primary beneficiary, as it does not direct the activities that most significantly impact the economic performance of this entity; therefore, the entity is accounted for under the equity method of accounting. At December 31, 2017, the Company had a negative investment basis of $752 million in this joint venture (negative $902 million at December 31, 2016), classified as "Other noncurrent obligations" in the consolidated balance sheets. The Company's maximum exposure to loss was zero at December 31, 2017 (zero at December 31, 2016). See Note 12 for additional information on this joint venture.

Silicon joint ventures
Also as a result of the DCC Transaction, the Company holds minority voting interests in certain joint ventures that produce silicon inputs for the Company. These joint ventures operate under supply agreements that sell inventory to the equity owners using pricing mechanisms that guarantee a return, therefore shielding the joint ventures from the obligation to absorb expected losses. As a result of the pricing mechanisms of these agreements, these entities are determined to be VIEs. The Company is not the primary beneficiary, as it does not hold the power to direct the activities that most significantly impact the economic performance of these entities; therefore, the entities are accounted for under the equity method of accounting. The Company's maximum exposure to loss as a result of its involvement with these variable interest entities is determined to be the carrying value of the investment in these entities. At December 31, 2017, the Company's investment in these joint ventures was $103 million ($96 million at December 31, 2016), classified as "Investment in nonconsolidated affiliates" in the consolidated balance sheets, representing the Company's maximum exposure to loss.

AFSI
The Company holds variable interests in AFSI, a company that produces and sells proprietary technologies for the horticultural market. The variable interests in AFSI relate to a sublease agreement between Dow and AFSI, and a tax receivable agreement that entitles Dow to additional consideration in the form of tax savings, which is contingent on the operations and earnings of AFSI. The Company is not the primary beneficiary, as Dow is a minority shareholder in AFSI and AFSI is governed by a board of directors, the composition of which is mandated by AFSI's corporate governance requirements that a majority of the directors be independent. The Company's investment in AFSI was $51 million at December 31, 2017 ($46 million at December 31, 2016), classified as "Investment in nonconsolidated affiliates" in the consolidated balance sheets. In the fourth quarter of 2016, as a result of a decline in the market value of AFSI, the Company recognized a $143 million pretax impairment charge related to its equity interest in AFSI (see Notes 12 and 22 for further information).

On April 4, 2017, the Company and AFSI revised certain agreements related to the divestiture of the AgroFresh business, including termination of an agreement related to a receivable for six million warrants, which was valued at $1 million at December 31, 2016. The Company also entered into an agreement to purchase up to 5,070,358 shares of AFSI's common stock, which represented approximately 10 percent of AFSI's common stock outstanding at signing of the agreement, subject to certain terms and conditions. At December 31, 2017, the Company had a receivable with AFSI related to the tax receivable agreement of $4 million ($12 million at December 31, 2016), classified as "Accounts and notes receivable - Other" in the consolidated balance sheets. The Company's maximum exposure to loss was $55 million at December 31, 2017 ($59 million at December 31, 2016).

Crude acrylic acid joint venture
The Company held a variable interest in a joint venture that manufactured crude acrylic acid in the United States and Germany on behalf of the Company and the other joint venture partner. The variable interest related to a cost-plus arrangement between the joint venture and each joint venture partner. The Company was not the primary beneficiary, as a majority of the joint venture’s output was committed to the other joint venture partner; therefore, the entity was accounted for under the equity method of accounting.

In the fourth quarter of 2017, the joint venture was dissolved by mutual agreement with return of the originally contributed assets to the partners. The carrying value of the Company's investment prior to the dissolution was $168 million, which was also determined to be fair value, therefore, no gain or loss was recognized as a result of the transaction. The fair value of assets recognized included $47 million of cash, $67 million of other assets and $48 million of goodwill (net of $6 million settlement of an affiliate's pre-existing obligation). At December 31, 2016, the Company’s investment in the joint venture was $171 million, classified as “Investment in nonconsolidated affiliates” in the consolidated balance sheets.
