The carrying amount of goodwill for the periods ended December 31, 2011 and December 31, 2010 was $43,825,000, of which $40,614,000 is attributable to the Company's Rail Products segment and $3,211,000 is attributable to Construction Products segment.

As part of our procedures to determine fair values of all acquired assets, we determined the fair value of technology, intellectual property, goodwill and other intangible assets.

Identified intangible assets as of December 31, 2011 of $2,305,000 are attributable to the Company's Construction Products segment and $44,457,000 are attributable to the Company's Rail Products segment.  The components of the Company's intangible assets are as follows:

In conjunction with the acquisition of Portec, the Company recorded the fair values of the acquired intangible assets in accordance with ASC 805, Business Combinations.  As part of our procedures to determine fair values of all acquired assets the Company evaluated the technology and intellectual property along with other intangible assets that could be assigned a fair value under the acquisition.  The Company developed historical and projected cash flows of the technology-based product lines along with an estimate of future costs to maintain these technologies.  These estimates and other assumptions were used to determine the present value of the discounted cash flows of these various technologies.  In addition, the Company evaluated the future lives of the identified intangible assets to determine if they have definite or indefinite lives.

As a result of the Portec acquisition, the Company assigned a fair value of $6,280,000 to trademarks, $19,230,000 to technology-based product lines, $18,160,000 to customer relationships and $350,000 to a supplier relationship.  Several factors were considered that contributed to the fair value of these intangible assets, including, but not limited to, the Company's position within the global railway supply industry, the level of competition that exists, the life-cycle of the product categories, and the acceptance of the technologies within the global railway supply industry.

As a result of the IDSI acquisition, the Company assigned a fair value of $30,000 to non-compete agreements and $1,800,000 to customer relationships.  These identified intangible assets are being amortized over their respective useful lives identified in the above table.

Intangible assets are amortized over their useful lives ranging from 5 to 25 years, with a total weighted average amortization period of approximately 20 years.  Amortization expense for years ended December 31, 2011, 2010 and 2009 was approximately $2,818,000, $445,000 and $13,000, respectively.

Estimated amortization expense over the succeeding five years and thereafter is as follows:
