Intangible assets with definite useful lives are amortized over their estimated lives and are tested for impairment whenever indicators of impairment arise. The following is a summary of other intangible assets (in thousands):

	December 31, 2011
	Gross Carrying Amount		Accumulated Amortization			Net
Resident relationships	$	3,169	$	(3,167	)	$	2
Operating lease intangible and renewal options		11,665		(2,705	)		8,960
Non-compete agreements		331		(265	)		66
Total	$	15,165	$	(6,137	)	$	9,028

The resident relationships and non-compete agreements were fully amortized as of second and fourth quarter of 2012, respectively. The remaining balance of $8.7 million of unamortized operating lease intangible was written off in connection with the purchase of the underlying leased properties in the second quarter of 2012.

Amortization expense related to definite-lived intangible assets for the years ended December 31, 2012, 2011 and 2010, was $0.4 million, $1.2 million, and $1.6 million, respectively.
