Notes to Consolidated Financial Statements

(Unaudited)

Our consolidated financial statements include the accounts of Forestar Group Inc., all subsidiaries, ventures and other entities in which we have a controlling interest and variable interest entities of which we are the primary beneficiary. We eliminate all material intercompany accounts and transactions. Noncontrolling interests in consolidated pass-through entities are recognized before income taxes. We account for our investment in other entities in which we have significant influence over operations and financial policies using the equity method (we recognize our share of the entities’ income or loss and any preferential returns and treat distributions as a reduction of our investment). We account for our investment in other entities in which we do not have significant influence over operations and financial policies using the cost method (we recognize as income distributions of accumulated earnings).

We prepare our unaudited interim financial statements in accordance with U.S. generally accepted accounting principles and Securities and Exchange Commission requirements for interim financial statements. As a result, they do not include all the information and disclosures required for complete financial statements. However, in our opinion, all adjustments considered necessary for a fair presentation have been included. Such adjustments consist only of normal recurring items unless otherwise noted. We make estimates and assumptions about future events. Actual results can, and probably will, differ from those we currently estimate including those related to allocating cost of sales to real estate, minerals and fiber and measuring assets for impairment. These interim operating results are not necessarily indicative of the results that may be expected for the entire year. For further information, please read the financial statements included in our 2011 Annual Report on Form 10-K.

Accounting Standards Adopted in 2012

In first quarter 2012, we adopted Accounting Standards Update (ASU) 2011-04 — Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs and ASU 2011-05 — Comprehensive Income (Topic 220): Presentation of Comprehensive Income . Adoption of these pronouncements did not affect our earnings or financial position.

Pending Accounting Standards

Pending ASU 2011-10 – Property, Plant, and Equipment: Derecognition of in Substance Real Estate will be effective first quarter 2013. Adoption is not anticipated to have a significant effect on our earnings or financial position but may result in certain additional disclosures.

In first quarter 2012, we acquired from CL Realty, L.L.C. and Temco Associates, LLC, the ventures’ interest in 17 residential and mixed-use real estate projects for $47,000,000. Subsequent to closing of these acquisitions, we received $23,370,000 from the ventures, representing our pro-rata share of distributable cash. The purchase price was allocated to the acquired assets and liabilities based on their estimated fair value: $31,891,000 to real estate; $14,236,000 to investment in unconsolidated ventures; $1,385,000 to other assets; and $512,000 to liabilities directly related to the real estate acquired. Transaction costs of about $463,000 are included in other operating expense in first six months 2012.

The acquired assets and operating results are included within our real estate segment and represented approximately 1,130 fully developed lots, 4,900 planned lots and over 460 commercial acres on the date of acquisition, principally in the major markets of Texas. Pro forma consolidated operating income (loss) assuming these acquisitions had occurred at the beginning of 2011 would not be significantly different than those reported.

On June 3, 2012, we entered into a definitive agreement to acquire CREDO Petroleum Corporation (Credo) in an all cash transaction for $14.50 per share, representing an equity purchase price of approximately $146,000,000. Closing is subject to customary conditions, including approval by Credo’s stockholders and, if approved, is expected to close in second half of 2012. We obtained a commitment for bridge financing that, combined with available liquidity, is sufficient to fund the acquisition. However, we intend to pursue amendments to our senior secured credit facility to fund a significant portion of the purchase price.

In second quarter 2012, we incurred $2,461,000 in costs to outside advisors related to this proposed transaction, which are included in general and administrative expenses. We estimate remaining transaction costs will be approximately $4,500,000.

Real estate consists of:

Included in entitled, developed and under development projects are the estimated costs of assets we expect to convey to utility and improvement districts of $53,053,000 at second quarter-end 2012 and $61,526,000 at year-end 2011, including $34,402,000 in second quarter-end 2012 and $34,802,000 at year-end 2011 related to our Cibolo Canyons project near San Antonio, Texas. These costs relate to water, sewer and other infrastructure assets we have submitted to utility or improvement districts for approval and reimbursement. In second quarter 2012, these costs decreased by $11,065,000 as result of a consolidated venture’s sale of approximately 800 acres near Dallas. We submitted for reimbursement to these districts $2,350,000 in first six months 2012 and $2,336,000 in first six months 2011. We received $637,000 from these districts in first six months 2012 and $187,000 in first six months 2011. We expect to collect the remaining amounts billed when these districts achieve adequate tax bases to support payment.

Also included in entitled, developed and under development projects is our investment in the resort development owned by third parties at our Cibolo Canyons project. We received $300,000 in second quarter 2012 and $1,603,000 in second quarter 2011 from the Special Improvement District (SID) related to hotel occupancy revenues and other revenues from resort sales collected as taxes by the SID. We currently account for these receipts as a reduction of our investment. At second-quarter-end 2012, we have $35,067,000 invested in the resort development.

In first quarter 2012, entitled, developed and under development projects increased by $31,891,000 as a result of our acquisition of certain residential and mixed-use projects from CL Realty and Temco. Please read Note 3 for additional information. In second quarter 2012, entitled, developed and under development projects decreased by $51,493,000 as result of a consolidated venture’s sale of approximately 800 acres (Light Farms Project) near Dallas. We received $24,294,000 in net proceeds, the buyer assumed the outstanding debt of $30,991,000 and we recognized a gain on sale of $3,401,000.

At second quarter-end 2012, commercial and income producing properties primarily represents our investment in a 401 unit multifamily property in Houston with a carrying value of $46,001,000, a 413 room hotel in Austin with a carrying value of $20,480,000 and a 289 unit multifamily project in Austin, currently under construction, with a carrying value of $29,011,000. In first six months 2012, we invested $14,341,000 in construction costs associated with this multifamily property and the estimated cost to complete construction is approximately $4,854,000.

Depreciation expense, primarily related to commercial and income producing properties, was $1,812,000 in first six months 2012 and $1,760,000 in first six months 2011 and is included in other operating expenses.

We own directly or through ventures about 129,000 acres of timber, primarily in Georgia, and about 17,000 acres of timber under lease. The non-cash cost of timber cut and sold was $411,000 in first six months 2012 and $524,000 in first six months 2011.
