6.	Goodwill

In the third quarter of 2011, the Company identified errors in its consolidated financial statements for the year ended December 31, 2010 and for each of the quarterly periods ended March 31, 2011 and June 30, 2011. The errors were due to the amount of recorded goodwill in connection with the 2010 acquisition of Enfora. The errors were made in connection with the Company's initial allocation of the consideration transferred in the acquisition resulting in understated goodwill and overstated acquired intangibles at the time of the acquisition by $1.7 million. As a result, the Company adjusted the gross value of goodwill and acquired intangible by $1.7 million to reflect the proper allocation.

The changes in the carrying amount of goodwill for the years ended December 31, 2011 and 2010 are as follows (in thousands):


	M2M Products and Solutions
	2011			2010
Balance at beginning of period	$	22,258		$	—
Goodwill acquired during the period		—			22,258
Goodwill acquisition price correction		1,700			—
Net deferred tax asset related adjustment due to goodwill correction		(612	)		—
Completion of deferred tax asset valuation (Note 2)		(297	)		—
Goodwill impairment during the period		(3,277	)		—

Balance at December 31,	$	19,772		$	22,258

During the third quarter of 2011, the Company experienced a sustained, significant decline in its stock price and based on actual and forecasted operating results of the M2M products and solutions reporting unit, the Company determined there were sufficient indicators of impairment present to require an interim impairment analysis.

Based upon fair value tests performed by a third party independent appraisal, the Company recorded a preliminary pre-tax goodwill impairment charge of approximately $3.5 million during the third quarter of 2011. In the fourth quarter of 2011, the Company finalized the impairment by reducing the previous estimate of impairment by approximately $237,000 for a total goodwill impairment of $3.3 million in 2011.

There were no further adjustments to the goodwill during its annual impairment test in the fourth quarter of 2011. The Company used the third party independent appraisal report from the third quarter of 2011 as its basis for its annual impairment analysis.
