In accordance with GAAP, loans held for sale and other real estate assets are not included in our assessment of the Allowance.

Changes in the allowance for loan and lease losses for impaired loans (included in the above amounts) were as follows:

	Year Ended December 31,
	2014			2013			2012
	(Dollars in thousands)

Balance, beginning of year	$	349		$	3,011		$	772
Provision for loan and lease losses	1,354			—			2,520
Other changes	(170		)	(2,662		)	(281		)
Balance, end of year	$	1,533		$	349		$	3,011

The amounts included in other changes above represent net charge-offs and net transfers of allocated allowances for loans and leases that were not classified as impaired for the entire year. At December 31, 2014 and 2013, all impaired loans were measured based on the fair value of the underlying collateral for collateral-dependent loans or at the loan’s observable market price.

In determining the amount of our Allowance, we rely on an analysis of our loan portfolio, our experience and our evaluation of general economic conditions, as well as regulatory requirements and input. If our assumptions prove to be incorrect, our current Allowance may not be sufficient to cover future loan losses and we may experience significant increases to our Provision.
