E. Inventories

Our major classes of inventories were as follows as of December 31, 2011 and 2010 (in thousands):

	December 31,

	2011		2010
Raw materials	$	1,892	$	2,332
Work in process		3,696		55
Finished goods		9,618		13,957

Total inventories	$	15,206	$	16,344

Included in work in process and finished goods inventories as of December 31, 2011 and 2010 was approximately $3.0 million and $1.5 million, respectively, of Feraheme produced in third-party manufacturing facilities and using processes for which we have not yet received regulatory approval. We believe future regulatory approval of these facilities and processes is probable and that this inventory is realizable.

On a quarterly basis, we analyze our inventory levels to determine whether we have any obsolete, expired, or excess inventory. If any inventory is expected to expire prior to being sold, has a cost basis in excess of its net realizable value, is in excess of expected sales requirements as determined by internal sales forecasts, or fails to meet commercial sale specifications, the inventory is written-down through a charge to cost of goods sold. The determination of whether inventory costs will be realizable requires estimates by management. A critical input in this determination is future expected inventory requirements, based on internal sales forecasts. Once packaged, Feraheme currently has a shelf-life of four years in the U.S., and as a result of comparison to internal sales forecasts, we expect to fully realize the carrying value of our current Feraheme inventory. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. Charges for inventory write-downs are not reversed if it is later determined that the product is saleable.

Equity-based compensation of approximately $0.1 million and $0.8 million was capitalized into inventory for the years ended December 31, 2011 and 2010, respectively.
