Disclosure of Fair Value of Financial Instruments	Note 9: Disclosure of Fair Value of Financial Instruments In addition to the disclosures in Note 10 for assets which are recorded at fair value, GAAP also requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value. The following disclosure of estimated fair value was determined by NPAMLP using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts NPAMLP could realize on disposition of the financial instruments at September 30, 2012 and December 31, 2011. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Cash equivalents, receivables, accounts payable, accrued expenses and other liabilities are carried at amounts which reasonably approximate their fair values due to their short term nature as of September 30, 2012 and December 31, 2011. Investment securities available for sale are carried at fair value and valued based on quoted market prices in an exchange and active markets. During the nine month period ended September 30, 2012, NPAMLP sold its entire portfolio of investment securities. In accordance with FASB authoritative guidance, NPAMLP has determined the estimated fair value of its wraparound mortgages based on discounted future cash flows at a current market rate. Management estimates that the carrying value approximates the estimated fair value of the wraparound mortgages at September 30, 2012 and December 31, 2011. NPAMLP classifies the fair value of the wraparound mortgages within Level 3 of the valuation hierarchy based on the significance of certain of the unobservable inputs used to estimate their fair values. Disclosure about fair value of financial instruments is based on pertinent information available to management as of September 30, 2012 and December 31, 2011. Although NPAMLP is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2011 and current estimates of fair value may differ significantly from the amounts presented herein.

Disclosure of Fair Value of Financial Instruments

Note 9: Disclosure of Fair Value of Financial Instruments

In addition to the disclosures in Note 10 for assets which are recorded at fair value, GAAP also requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value. The following disclosure of estimated fair value was determined by NPAMLP using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts NPAMLP could realize on disposition of the financial instruments at September 30, 2012 and December 31, 2011. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Cash equivalents, receivables, accounts payable, accrued expenses and other liabilities are carried at amounts which reasonably approximate their fair values due to their short term nature as of September 30, 2012 and December 31, 2011. Investment securities available for sale are carried at fair value and valued based on quoted market prices in an exchange and active markets. During the nine month period ended September 30, 2012, NPAMLP sold its entire portfolio of investment securities.

In accordance with FASB authoritative guidance, NPAMLP has determined the estimated fair value of its wraparound mortgages based on discounted future cash flows at a current market rate. Management estimates that the carrying value approximates the estimated fair value of the wraparound mortgages at September 30, 2012 and December 31, 2011. NPAMLP classifies the fair value of the wraparound mortgages within Level 3 of the valuation hierarchy based on the significance of certain of the unobservable inputs used to estimate their fair values. Disclosure about fair value of financial instruments is based on pertinent information available to management as of September 30, 2012 and December 31, 2011.
