For the quarter ended December 31, 2010, the net interest margin was 2.87%, as compared to 3.30% for the same period in 2009. The decrease in the net interest margin was primarily due to the shift in the relative composition of interest-earning assets to increased amounts of cash and cash equivalents as higher yielding investment securities were called and repaid during the later part of fiscal 2010 and first quarter of fiscal 2011.
The Company established a provision for loan losses of $580,000 for the quarter ended December 31, 2010, compared to $135,000 for the same quarter in 2009. The increased provision for the 2010 period primarily related to an additional specific reserve of $315,000 established with respect to an 18-unit condominium project located in Philadelphia in which the estimated net realizable value of the collateral has been determined to be less than the $4.2 million loan balance based on a recent appraisal. Although the loan is impaired, the loan is not considered non-performing as the loan is not delinquent or in non-accrual status. At December 31, 2010, the Company's non-performing assets totaled $9.5 million or 1.8% of total assets as compared to $6.7 million or 1.4% at September 30, 2010. The non-performing assets consisted of one construction loan totaling $206,000, three commercial real estate loans to two borrowers totaling $898,000, 24 one-to four-family residential mortgage loans totaling $6.3 million and five real estate owned properties representing two projects totaling $2.0 million. The allowance for loan losses totaled $3.7 million, or 1.4% of total loans and 50.2% of non-performing loans at December 31, 2010.
Non-interest income amounted to $134,000 for the three months ended December 31, 2010, compared with $19,000 for the same period in 2009. The improvement compared to the 2009 period was due to the reduced level of other than temporary impairment ("OTTI") charges arising from the Company's redemption in kind in June 2008 of its entire investment in a mutual fund. The decline in the amount of losses recognized between the 2009 and 2010 periods reflected the decline in the amount of the OTTI charges from $204,000 for the three months ended December 31, 2009 to $95,000 for the three months ended December 31, 2010 related to the non-agency mortgage-backed securities acquired as part of the redemption in kind of such investment.
