FTS International, Inc. FTS International, Inc. (FTS), based in Fort Worth, Texas, is a privately held company which, through its subsidiaries, provides hydraulic fracturing and other services to oil and gas companies.

In 2012, we recorded negative equity method adjustments, prior to intercompany profit eliminations, of $91 million for our share of FTS’s net loss and recorded accretion adjustments of $45 million related to the excess of our underlying equity in net assets of FTS over our carrying value. We also funded a capital call of $3 million in 2012. The carrying value of our investment in FTS was less than our underlying equity in net assets by approximately $622 million as of December 31, 2012, of which $296 million was attributed to goodwill. The value attributed to goodwill decreased by $200 million during 2012, which represents our proportionate share, net of tax, of an impairment recorded by FTS related to its goodwill. The value not attributed to goodwill is being accreted over the nine-year estimated useful lives of the underlying assets.

In addition, in November 2012, we purchased our pro-rata share, equal to approximately $106 million, of preferred equity securities offered by FTS to existing stockholders. Each share of preferred stock is convertible into a specified number of shares of FTS common stock automatically upon a qualified initial public offering of FTS common stock and at our option at any time following the second anniversary of the issue date.

Chaparral Energy, Inc. Chaparral Energy, Inc., based in Oklahoma City, Oklahoma, is a private independent oil and natural gas company engaged in the production, acquisition and exploitation of oil and natural gas properties.

In 2012, we recorded a positive equity method adjustment of $4 million related to our share of Chaparral's net income, a $3 million charge related to our share of its other comprehensive income, and an amortization adjustment of $3 million related to our carrying value in excess of our underlying equity in net assets. The carrying value of our investment in Chaparral was in excess of our underlying equity in net assets by approximately $52 million as of December 31, 2012. This excess is attributed to the natural gas and oil reserves held by Chaparral and is being amortized over the estimated life of these reserves based on a unit of production rate.

Sundrop Fuels, Inc. In July 2011, we agreed to invest $155 million in preferred equity securities of Sundrop Fuels, Inc., a privately held cellulosic biofuels company based in Longmont, Colorado. The investment is being used to fund construction of a nonfood biomass-based “green gasoline” plant, capable of annually producing more than 40 million gallons of gasoline from natural gas and waste cellulosic material. The investment is intended to accelerate the development of an affordable, stable, room-temperature, natural gas-based fuel for immediate use in automobiles, diesel engine vehicles and aircraft. As of December 31, 2012, we had funded $115 million of our commitment, of which $80 million was funded in 2012. The remaining tranches of preferred equity investment will be scheduled around certain funding and operational milestones that are expected to be reached by July 2013. The full investment will represent approximately 50% of Sundrop Fuels’ equity on a fully diluted basis.

In 2012, we recorded a $3 million charge related to our share of Sundrop’s net loss. The carrying value of our investment in Sundrop was in excess of our underlying equity in net assets by approximately $53 million as of December 31, 2012. This excess will be amortized over the life of the plant, once it is placed into service.

Clean Energy Fuels Corp. In July 2011, we agreed to invest $150 million in newly issued convertible promissory notes of Clean Energy Fuels Corp. (Nasdaq:CLNE), based in Seal Beach, California. The investment is being made in three equal $50 million promissory notes, the first two of which were issued in July 2011 and July 2012, with the remaining note scheduled to be issued in June 2013. The notes bear interest at the annual rate of 7.5%, payable quarterly, and are convertible at our option into shares of Clean Energy’s common stock at a 22.5% conversion premium, resulting in a conversion price of $15.80 per share. Under certain circumstances following the second anniversary of the issuance of a note, Clean Energy can force conversion of the debt. The entire principal balance of each note is due and payable seven years following issuance. Clean Energy is using our $150 million investment to accelerate its build-out of LNG fueling infrastructure for heavy-duty trucks at truck stops across interstate highways in the U.S.

In December 2011, we also purchased one million shares of Clean Energy common stock for $10 million and classified this investment as available-for-sale and reported it at fair value. During 2012, the carrying value of our investment remained the same as the common stock price of Clean Energy changed from $12.46 per share as of December 31, 2011 to $12.45 per share as of December 31, 2012. Through December 31, 2012, we had recorded a mark-to-market pre-tax gain of $2 million in accumulated other comprehensive income for this investment.

Twin Eagle Resource Management LLC. In 2010, we invested $20 million in Twin Eagle Resource Management LLC, a natural gas trading and management firm. During 2012, we invested an additional $19 million and we recorded a $5 million charge related to our share of Twin Eagle’s net loss.

Maalt Specialized Bulk, LLC. In 2011, PTL Prop Solutions, LLC, a wholly owned subsidiary of Chesapeake, invested $12 million in Maalt Specialized Bulk, LLC (Maalt), which engages in bulk transportation services of sand. In 2012, we funded an additional investment of $1 million related to Maalt meeting certain performance targets as outlined in our investment agreement.

Gastar Exploration Ltd. Gastar Exploration Ltd. (NYSE MKT:GST), based in Houston, Texas, is an independent energy company engaged in the exploration, development and production of natural gas and oil in the U.S. Our investment in Gastar has a cost basis of $89 million and is classified as available-for-sale, and reported at fair value. During 2012, the carrying value of our investment decreased as the common stock price of Gastar decreased from $3.18 per share as of December 31, 2011 to $1.21 per share as of December 31, 2012. In March 2009, we booked an other-than-temporary-impairment of $70 million, and, through December 31, 2012, we had recorded a mark-to-market pre-tax loss of $11 million in accumulated other comprehensive income for this investment.
