5. RESTRUCTURING

On November 14, 2011, we announced the decision to focus on the development of our oncology programs and consequently, we discontinued further development of our stem cell programs. With this decision, a total of 66 full-time positions were eliminated. Of those, as of March 31, 2012, 14 employees are continuing to provide services through various dates in the first half of 2012.

The outstanding restructuring liability is included in accrued restructuring charges on our condensed consolidated balance sheet as of March 31, 2012 and the components are summarized in the following table (in thousands):

	Employee Severance
	And Other Benefits
Beginning accrual balance as of December 31, 2011	$	3,730
Cash payments		(2,287	)
Adjustments or non-cash credits		(26	)
Ending accrual balance as of March 31, 2012	$	1,417

We may incur additional charges as a result of the restructuring as we exit one of the three buildings in which we lease space in Menlo Park, California. Such charges, if any, will be recorded as they are determined. We also plan to sell any excess equipment, the net proceeds of which may offset some of these future charges.
