20. Acquisitions

InterOil Corporation

On February 22, 2017, the Corporation completed the acquisition of InterOil Corporation (IOC) for $2.7 billion. The IOC acquisition was mostly unproved properties in Papua New Guinea. Consideration included 28 million shares of Exxon Mobil Corporation common stock having a value on the acquisition date of $2.2 billion, a Contingent Resource Payment (CRP) with a fair value of $0.3 billion and cash of $0.2 billion. The CRP provided IOC shareholders $7.07 per share in cash for each incremental independently certified Trillion Cubic Feet Equivalent (TCFE) of resources above 6.2 TCFE, up to 11.0 TCFE. IOC’s assets include a contingent receivable related to the same resource base for volumes in excess of 3.5 TCFE at amounts ranging from $0.24 - $0.40 per thousand cubic feet equivalent. The fair value of the contingent receivable was $1.1 billion at the acquisition date. Fair values of contingent amounts were based on assumptions about the outcome of the resource certification, future business plans and appropriate discount rates.

On September 6, 2017, the resource certification was finalized triggering both payment of the CRP to former IOC shareholders and receipt of the current portion of the contingent receivable. The earnings impact from settlement of the CRP and the related contingent receivable was not material.

Permian Basin Properties

On February 28, 2017, the Corporation completed the acquisition for $6.2 billion of a number of companies from the Bass family in Fort Worth, Texas, that indirectly own mostly unproved oil and gas properties in the Permian Basin. Consideration included 68 million shares of Exxon Mobil Corporation common stock having a value on the acquisition date of $5.5 billion, together with additional contingent cash payments tied to future drilling and completion activities (up to a maximum of $1.02 billion). Fair value of the contingent payment was $0.7 billion as of the acquisition date and is expected to be paid beginning in 2020 and ending no later than 2032 commensurate with development of the resource. Fair value of the contingent payment was based on assumptions including drilling and completion activities, appropriate discount rates and tax rates.

The fair value of the contingent payment is adjusted each quarter. The earnings impact from these adjustments was not material.
