Fair values of securities are estimated based on financial models or prices paid for similar securities. It is possible future interest rates could change considerably resulting in a material change in the estimated fair value.

Nonrated trust preferred securities at December 31, 2012 and 2011, consist of separate obligations issued by three holding companies headquartered in Wisconsin. One of the issuers with par value totaling $750 elected to defer payment of interest beginning in 2011, and that obligation was maintained on nonaccrual status at December 31, 2011. During 2012, past due interest on this issue was repaid, and all payments were current at December 31, 2012.

Nonrated senior subordinated notes at December 31, 2012 and 2011, consist of one obligation issued by a Wisconsin state chartered bank.

The following table indicates the number of months securities that are considered to be temporarily impaired have been in an unrealized loss position at December 31:

At December 31, 2012, 35 debt securities had unrealized losses with aggregate depreciation of 1.10% from the amortized cost basis, compared to 11 debt and equity securities which had unrealized losses with aggregate depreciation of 4.16% from the amortized cost basis at December 31, 2011. These unrealized losses relate principally to an increase in interest rates relative to interest rates in effect at the time of purchase or reclassification from available-for-sale to held-to-maturity classification and are not due to changes in the financial condition of the issuers. However, the unrealized loss on nonrated trust preferred securities is due to an increase in credit spreads for risk on such investments demanded in the market. In analyzing an issuer’s financial condition, management considers whether the securities are issued by a government body or agency, whether a rating agency has downgraded the securities, industry analysts’ reports, and internal review of issuer financial statements. Since management does not intend to sell and has the ability to hold debt securities until maturity (or the foreseeable future for securities available for sale), no declines are deemed to be other than temporary.

The amortized cost and estimated fair value of debt securities and nonrated trust preferred securities and senior subordinated notes at December 31, 2012, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Securities with a fair value of $44,914 and $56,659 at December 31, 2012 and 2011, respectively, were pledged to secure public deposits, other borrowings, and for other purposes required by law.

There were no sales of securities during 2012. During 2011, PSB realized a gain of $32 ($19 after tax expense) from the sale of its remaining investment in FNMA preferred stock generating proceeds of $37. There was no sale of securities during 2010. However, during 2010, PSB realized a loss of $20 ($12 after tax benefits) on recognition of other-than-temporary impairment to the amortized cost basis of its investment in FNMA preferred stock.

During 2010, PSB transferred all of its municipal, trust preferred, and senior subordinated note securities from the available-for-sale classification to the held-to-maturity classification to better reflect its intent and practice to hold these long-term debt securities until maturity. Fair value of the securities was $54,130 at the time of the transfer, which included a $2,552 unrealized gain over the existing amortized cost basis. The unrealized gain will be amortized against the new cost basis (equal to transfer date fair value) over the remaining life of the securities.

Scheduled amortization at December 31, 2012, of the remaining unrealized gain is as follows:

2013	$	396
2014		335
2015		274
2016		194
2017		115
Thereafter		112
