At July 31, 2011 and October 31, 2010, the carrying value of cash and cash equivalents and restricted cash approximated fair value. Gibraltar’s investment in the portfolio of non-performing loans was recorded at fair value at inception based on the acquisition price as determined by Level 3 inputs. Due to the relatively short period of time since the Company’s acquisition of the investment and the absence of any significant evidence to the contrary, the Company believes the fair value of these financial instruments approximate their carrying values at July 31, 2011.
At the end of the reporting period, the Company determines the fair value of its mortgage loans held for sale and the forward loan commitments it has entered into as a hedge against the interest rate risk of its mortgage loans using the market approach to determine fair value. The evaluation is based on the current market pricing of mortgage loans with similar terms and values as of the reporting date and by applying such pricing to the mortgage loan portfolio. The Company recognizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale as a gain or loss. In addition, the Company recognizes the fair value of its forward loan commitments as a gain or loss. These gains and losses are included in interest and other income. Interest income on mortgage loans held for sale is calculated based upon the stated interest rate of each loan and is included in “interest and other income”.
The table below provides, for the periods indicated, the aggregate unpaid principal and fair value of mortgage loans held for sale as of the date indicated (amounts in thousands).

IRLCs represent individual borrower agreements that commit the Company to lend at a specified price for a specified period as long as there is no violation of any condition established in the commitment contract. These commitments have varying degrees of interest rate risk. The Company utilizes best-efforts forward loan commitments (“Forward Commitments”) to hedge the interest rate risk of the IRLCs and residential mortgage loans held for sale. Forward Commitments represent contracts with third-party investors for the future delivery of loans whereby the Company agrees to make delivery at a specified future date at a specified price. The IRLCs and Forward Commitments are considered derivative financial instruments under ASC 815, “Derivatives and Hedging”, which requires derivative financial instruments to be recorded at fair value. The Company estimates the fair value of such commitments based on the estimated fair value of the underlying mortgage loan and, in the case of IRLCs, the probability that the mortgage loan will fund within the terms of the IRLC. To manage the risk of nonperformance of investors regarding the Forward Commitments, the Company assesses the credit worthiness of the investors on a periodic basis.

The Company recognizes inventory impairment charges based on the difference in the carrying value of the inventory and its fair value at the time of the evaluation. The fair value of the aforementioned inventory was determined using Level 3 criteria. See Note 1, Significant Accounting Policies, “Inventory” for additional information regarding the Company’s methodology on determining fair value.
