Restructuring

2008 Plan

In December 2008, our management approved, committed to, and initiated a restructuring plan, or the 2008 Plan, to improve efficiencies in our operations, which was largely driven by our plan to consolidate our facility in Carlsbad, California into the Longmont, Colorado facility. As a result of this relocation, we terminated approximately 70 California employees whose positions were relocated to Colorado and incurred approximately $1.5 million in severance-related costs, all of which was recognized and paid as of December 31, 2010.

As part of the 2008 Plan, we also incurred contract termination costs of $3.6 million since the inception of the 2008 Plan through September 30, 2011. We record charges for contract termination and other associated costs as restructuring expense, which is presented as a separate component within operating expenses. Accrued contract termination and other associated costs are recorded in the restructuring accrual line on our consolidated balance sheets. We expect to pay these contract lease termination costs over the remainder of the lease term ending in January 2013. Based on our estimates, we do not expect to receive any material amounts of sublease income through the remainder of the lease term.

The following table summarizes our 2008 Plan activities (in thousands):



	Contract Termination and Other Associated Costs
Accrued restructuring balance as of December 31, 2010	$	1,500
Restructuring plan expense	621
Cash payments	(909		)
Accrued restructuring balance as of December 31, 2011	1,212
Restructuring plan expense	57
Adjustments to restructuring plan	(247		)
Cash payments	(877		)
Accrued restructuring balance as of December 31, 2012	$	145

The adjustment to the 2008 Plan resulted from certain credits received in the first quarter of 2012 for previously paid common area maintenance (CAM) charges relating to our lease of the Carlsbad, California facility. We recorded this benefit as a reduction of restructuring expense, which is presented as a separate component within operating expenses.

During July 2012, we signed an amendment to our lease of the Carlsbad facility abating approximately $0.2 million in rent and other operating expenses in lieu of allowing the landlord to use the facility for the remainder of the lease term.

2010 Plan

In the second quarter of 2010, our management approved, committed to, and initiated a restructuring and cost reduction plan, or the 2010 Plan, to better align our resources in order to lower our breakeven point. The 2010 Plan included severance and related costs for the reduction of approximately 10% of our workforce, and fees associated with the acceleration of the closure of our Carlsbad, California facility. As a result of these actions, we intended to terminate approximately 26 employees located in the United States, of which 25 had been terminated as of September 30, 2011. We expected to incur approximately $0.4 million in severance-related costs, all of which were recognized as of December 31, 2010. Accrued severance-related costs are recorded in the restructuring accrual line on our consolidated balance sheets. The remainder of the severance and related restructuring costs attributable to our 2010 Plan were paid out in the third quarter of 2011.

As part of the 2010 Plan, we also incurred contract termination costs of $0.3 million since the inception of the 2010 Plan through September 30, 2011 for facility lease and other associated costs that we continued to incur without economic benefit, as we exited the remaining portion of our Carlsbad, California facility. We record charges for contract termination costs and other associated costs as restructuring expense, which is presented as a separate component within operating expenses. Accrued contract termination and other associated costs are recorded in the restructuring accrual line on our consolidated balance sheets. Based on our estimates, we do not expect to receive any material amounts of sublease income through the remainder of the lease term.

The following table summarizes our 2010 Plan activities (in thousands):



	Severance and Related Costs			Contract Termination and Other Associated Costs			Total
Accrued restructuring balance as of December 31, 2010	$	20		$	144		$	164
Restructuring plan expense	—			62			62

The adjustment to the 2010 Plan resulted from certain credits received in the first quarter 2012, for previously paid CAM charges relating to our lease of the Carlsbad, California facility. We recorded this benefit as a reduction of restructuring expense, which is presented as a separate component within operating expenses.

2012 Plan

In the first quarter 2012, our management approved, committed to, and initiated a restructuring and cost reduction plan, or the 2012 Plan, that is associated with the closure of our Israel Technology Development Center. The 2012 Plan is designed to re-align our software investments to focus on accelerating the development of embedded software features, in order to launch a competitive set of mid-range storage array products in 2012, and to provide more differentiated entry-level products for both OEM and channel customers. As a result of these actions, we terminated all employees located in our Israel Technology Development Center as of December 31, 2012. We incurred a total of $0.4 million in severance-related costs as of December 31, 2012. Accrued severance-related costs are recorded in the restructuring accrual line on our consolidated balance sheets. The majority of severance related restructuring costs attributable to our 2012 Plan were paid out in the second quarter of 2012, with the remainder paid out in the third quarter of 2012. Substantially all of our 2012 Plan workforce reductions were completed by July 31, 2012.

As part of the 2012 Plan, we also expect to incur approximately $0.4 million in contract termination costs for facility lease and other associated costs that we continue to incur without economic benefit, as we exited our Petah Tivka, Israel facility. We record charges for contract termination costs and other associated costs as restructuring expense, which is presented as a separate component within operating expenses. Accrued contract termination and other associated costs are recorded in the restructuring accrual line on our consolidated balance sheets. We paid the majority of the contract lease termination costs over the remainder of the facility lease term ending in December 2012. Approximately $0.2 million of our contractual commitments are expected to remain obligations of the Company through December 2013.

The majority of the activities comprising the 2012 Plan were completed by the end of 2012.

The following table summarizes our 2012 Plan activities (in thousands):



	Severance and Related Costs			Contract Termination and Other Associated Costs			Total
Restructuring plan charges	$	440		$	332		$	772
Reclassification of customer deposits	—			206			206
Cash payments	(440		)	(332		)	(772		)
Accrued restructuring balance as of December 31, 2012	$	—		$	206		$	206

As part of the 2012 Plan, the Company announced that it will no longer support the UVS product effective March 31, 2013. The adjustment to the 2012 Plan represents customer prepaid UVS maintenance agreements for terms covering periods after March 31, 2013 that we expect will require future refunds to those customers impacted by this decision. As these were previously recognized as a component of deferred revenue, there was no impact to earnings, but this adjustment reflects a reclassification within the balance sheet as of December 31, 2012.
