ACQUISITIONS AND DISPOSITIONS	ACQUISITIONS AND DISPOSITIONS Sale of California Precast Operations On August 2, 2012, we executed a definitive asset purchase agreement to sell substantially all of the Company’s California precast operations to Oldcastle Precast, Inc. ("Oldcastle") for $21.3 million in cash, plus net working capital adjustments. The assets purchased by Oldcastle included certain facilities, fixed assets, and working capital items. The transaction was completed on August 20, 2012. The results of operations for these units have been included in discontinued operations for the periods presented. In conjunction with the sale to Oldcastle, we also entered into certain sublease and license agreements with Oldcastle for certain land and property that is leased or owned by us. As the sublease and license agreements provide payment for the full amount of our obligation under the leases, we did not record any liability for exit obligations associated with these agreements. During the first quarter of 2013, we made payments totaling $1.9 million to Oldcastle related to the reacquisition of certain uncollected receivables as well as the settlement of certain accrued liabilities. At June 30, 2013, $0.4 million of the acquired receivables are recorded in other receivables on the condensed consolidated balance sheet. Purchase of Colorado River Concrete Assets On September 14, 2012, we purchased four ready-mixed concrete plants and related assets and inventory from Colorado River Concrete L.P., Cindy & Robin Concrete, L.P., and E&R Artecona Family Limited Partnership (collectively, "CRC") in our west Texas market for $2.4 million in cash and a $1.9 million promissory note at an annual interest rate of 4.5%. This note is being paid in twenty-four equal monthly installments which began in January 2013. We made cash payments on the promissory note of approximately $0.5 million during the six months ended June 30, 2013. The purchase of these assets allows us to expand our business in two of our major markets: west Texas and north Texas. We acquired plant and equipment valued at $3.2 million, inventory valued at $0.2 million, and goodwill valued at $1.0 million. No liabilities were assumed in the purchase. The goodwill ascribed to the purchase is related to the synergies we expect to achieve with expansion of these areas in which we already operate. We expect the goodwill to be deductible for tax purposes. Purchase of Bode Gravel and Bode Concrete Equity Interests On October 30, 2012, we completed the acquisition of all the outstanding equity interests of Bode Gravel Co. and Bode Concrete LLC (collectively, the "Bode Companies") pursuant to an equity purchase agreement dated October 17, 2012. The Bode Companies operated two fixed and one portable ready-mixed concrete plants and 41 mixer trucks in the San Francisco area, and produced approximately 243,000 cubic yards of ready-mix concrete in 2011. The purchase price for the acquisition was $24.5 million in cash, plus working capital and closing adjustments of $1.6 million, plus potential earn-out payments. The earn-out payments are contingent upon reaching negotiated volume hurdles, with an aggregate present value of up to $7.0 million in cash payable over a six-year period, resulting in total consideration fair value of $33.1 million. We funded the acquisition from cash on hand and borrowings under our 2012 Credit Agreement as defined in Note 8. The purchase price allocation has been prepared and recorded on a preliminary basis and may change as additional information becomes available regarding the fair value and tax basis of the assets and liabilities acquired. Changes to the purchase price allocation will be made as soon as practical, but no later than one year from the acquisition date of October 30, 2012. The excess of the purchase price over the fair values of the assets acquired and liabilities assumed represents the goodwill resulting from the acquisition. The goodwill ascribed to the purchase is related to the synergies we expect to achieve, as well as expansion of our business in the San Francisco, California area in which we already operate. We expect a portion of the goodwill to be deductible for tax purposes. See Note 14 for additional information regarding income taxes. Sale of Smith Precast Operations On December 17, 2012, we completed the sale of substantially all of our assets associated with our Smith Precast operations ("Smith") located in Phoenix, Arizona, to Jensen Enterprises, Inc. ("Jensen") for $4.3 million in cash and the assumption of certain obligations. The assets purchased by Jensen included certain facilities, fixed assets, and working capital items. In addition, Jensen assumed the obligations of a capital lease previously held by Smith. The results of operations for this unit have been included in discontinued operations for the periods presented. Other In October 2006, we acquired certain aggregates assets located in New Jersey. Pursuant to the purchase agreement, additional consideration would be due if we were able to receive permits that allowed us to mine the minerals from certain areas. In April 2012, we obtained the permits necessary to allow us to mine this area of property. Accordingly, we accrued $1.4 million in additional purchase consideration during the quarter ended June 30, 2012. On October 5, 2012, we signed an agreement with the seller to pay a total of $1.0 million in lieu of the $1.4 million contractual payment due to a lower volume of aggregate assets available to mine than originally contemplated in the agreement. We signed a promissory note for the $1.0 million settlement, payable in eight equal quarterly installments at an annual interest rate of 2.5%, which began in November 2012. We made cash payments on the promissory note of approximately $0.2 million during the six months ended June 30, 2013. In October 2010, we acquired three ready-mixed concrete plants and related assets and inventory in our west Texas market for approximately $3.0 million. We made cash payments of $0.4 million at closing and issued promissory notes for the remaining $2.6 million at an annual interest rate of 5%. We made cash payments on these notes of approximately $0.2 million during each of the six months ended June 30, 2013 and 2012. In August 2010, we entered into a redemption agreement to have our 60% interest in our Michigan subsidiary, Superior Materials Holdings, LLC (“Superior”), redeemed by Superior. At the closing of the redemption on September 30, 2010, we and certain of our subsidiaries paid $0.6 million in cash and issued a $1.5 million promissory note to Superior as partial consideration for certain indemnifications and other consideration provided by the minority owner and their new joint venture partner pursuant to the redemption agreement. In January 2012, we paid $0.8 million to complete payment of the note.
