NOTE 7. Marketable Securities

The Company invests in agency securities, corporate securities, asset-backed securities, treasury securities and other securities. The following is a summary of amounts recorded on the Consolidated Balance Sheet for marketable securities (current and non-current).

Classification of marketable securities as current or non-current is dependent upon management’s intended holding period, the security’s maturity date and liquidity considerations based on market conditions. If management intends to hold the securities for longer than one year as of the balance sheet date, they are classified as non-current. At September 30, 2009, gross unrealized losses totaled approximately $19 million (pre-tax), while gross unrealized gains totaled approximately $4 million (pre-tax). At December 31, 2008, gross unrealized losses totaled approximately $30 million (pre-tax), while gross unrealized gains were not material. Gross unrealized losses related to auction rate securities totaled $11 million and $16 million (pre-tax) as of September 30, 2009 and December 31, 2008, respectively. Gross realized gains and losses on sales or maturities of marketable securities for the first nine months of 2009 and 2008 were not material. Cost of securities sold or reclassified use the first in, first out (FIFO) method. Since these marketable securities are classified as available-for-sale securities, changes in fair value will flow through other comprehensive income, with amounts reclassified out of other comprehensive income into earnings upon sale or “other-than-temporary” impairment.

3M has a diversified marketable securities portfolio of $1.216 billion as of September 30, 2009. Within this portfolio, current and long-term asset-backed securities (estimated fair value of $412 million) are primarily comprised of interests in automobile loans and credit cards. At September 30, 2009, the asset-backed securities credit ratings were AAA or A-1+, with the following exceptions: three securities rated AA with a total fair value of $23 million, one security rated A with a fair value of less than $1 million, and one security rated BBB with a fair value of less than $1 million. Historically, 3M’s marketable securities portfolio included auction rate securities that represented interests in investment grade credit default swaps, however, these have been written down to $6 million as of September 30, 2009. Since the second half of 2007, these auction rate securities failed to auction due to sell orders exceeding buy orders. Liquidity for these auction-rate securities is typically provided by an auction process that resets the applicable interest rate at pre-determined intervals, usually every 7, 28, 35, or 90 days. The funds associated with failed auctions will not be accessible until a successful auction occurs or a buyer is found outside of the auction process. Based upon an analysis of “temporary” and “other-than-temporary” impairment factors, auction rate securities with an original par value of approximately $34 million were written-down to an estimated fair value of $1 million as of December 31, 2008 and adjusted to an estimated fair value of $6 million as of September 30, 2009. There are $11 million (pre-tax) of temporary impairments associated with auction rate securities at September 30, 2009, which were recorded as unrealized losses within other comprehensive income. As of September 30, 2009, these investments have been in a loss position for more than 12 months. 3M recorded “other-than-temporary” impairment charges that reduced pre-tax income by approximately $8 million in the second quarter of 2008, $1 million in the first quarter of 2008, and $8 million in the fourth quarter of 2007. Refer to Note 10 for a table that reconciles the beginning and ending balances of auction rate securities.

3M reviews impairments associated with the above in accordance with the measurement guidance provided by ASC 320, Investments-Debt and Equity Securities, when determining the classification of the impairment as “temporary” or “other-than-temporary. In addition, as discussed in Note 1, beginning in April 2009, the Company considers the new accounting standard with respect to the determination of “other-than-temporary” impairments associated with investments in debt securities. A temporary impairment charge results in an unrealized loss being recorded in the other comprehensive income component of equity. Such an unrealized loss does not reduce net income for the applicable accounting period because the loss is not viewed as other-than-temporary. The factors evaluated to differentiate between temporary and other-than-temporary include the projected future cash flows, credit ratings actions, and assessment of the credit quality of the underlying collateral, as well as the factors included in the impairment model for debt securities included in the new standard relating to “other-than temporary” impairments, as described in Note 1.

The balances at September 30, 2009 for marketable securities by contractual maturity are shown below. Actual maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

Of the $20 million in unrealized losses at September 30, 2009, $1 million arose within the last 12 months. The market value of the investments that have been in an unrealized loss position for less than 12 months and for 12 months and longer is $40 million and $42 million, respectively. The market value of United States government obligations, government-sponsored enterprise obligations, and other debt securities with unrealized losses as of September 30, 2009, is $54 million. The $3 million of unrealized losses associated with United States government obligations, government sponsored enterprise obligations and other debt securities are not considered to be other-than-temporary because the present value of expected cash flows to be collected is equivalent to or exceeds the amortized cost basis of the securities. The market value of available-for-sale equity securities with unrealized losses as of September 30, 2009, is $28 million. All of the $17 million in unrealized losses associated with available-for-sale equity securities is related to the Company’s investment in one security. The Company does not intend to sell any of its impaired debt and equity securities, and, based upon its evaluation, the Company does not believe it is likely that the Company will be required to sell the investments before recovery of their amortized cost bases which is expected in the foreseeable future.

Other-than-temporary impairment

Upon acquisition of a security, BNY Mellon decides whether it is within the scope of ASC 325 -Investments – Other or will be evaluated for impairment under the guidance within ASC 320. Subsequently, if the security is downgraded we do not alter this decision.

ASC 325 provides specific guidance for certain debt securities which are beneficial interests in securitized financial assets. Specifically, ASC 325 provides incremental impairment guidance for a subset of the debt securities within the scope of ASC 320. For securities where there is no debt rating at acquisition, and the security is a beneficial interest in securitized financial assets, BNY Mellon uses the ASC 325 impairment model. For securities where there is no debt rating at acquisition and the security is not a beneficial interest in securitized financial assets BNY Mellon uses the impairment model guidance under ASC 320.

We routinely conduct periodic reviews to identify and evaluate each investment security to determine whether OTTI has occurred. Economic models are used to determine whether an OTTI has occurred on these securities. While all securities are considered, the securities primarily impacted by OTTI testing are non-agency RMBS and HELOCs. For each non-agency RMBS in the investment portfolio (including but not limited to those whose fair value is less than their amortized cost basis), an extensive, regular review is conducted to determine if an OTTI has occurred. Various inputs to the economic models are used to determine if an unrealized loss on non-agency RMBS is other-than-temporary. The most significant inputs are:

•

Default rate – the number of mortgage loans expected to go into default over the life of the transaction, which is driven by the roll rate of loans in each performance bucket that will ultimately migrate to default; and

•

Severity – the loss expected to be realized when a loan defaults

To determine if the unrealized loss for non-agency RMBS is other-than-temporary, we project total estimated defaults of the underlying assets (mortgages) and multiply that calculated amount by an estimate of realizable value upon sale in the marketplace (severity) in order to determine the projected collateral loss. We also evaluate the current credit enhancement underlying the bond to determine the impact on cash flows. If we determine that a given RMBS position will be subject to a write-down or loss, we record the expected credit loss as a charge to earnings.

In addition, we have estimated the expected loss by taking into account observed performance of the underlying securities, industry studies, market forecasts, as well as our view of the economic outlook affecting bond collateral.

The table below shows the projected weighted-average default rates and loss severities for the recent-vintage (i.e. 2007, 2006 and late 2005) non-agency RMBS portfolios at Sept. 30, 2009 and Dec. 31, 2008.


Projected weighted-average default rates and severities
	Sept. 30, 2009				Dec. 31, 2008
	Default Rate		Severity		Default Rate		Severity
Alt-A	42	%	51	%	28	%	43	%
Subprime	74	%	70	%	56	%	59	%
Prime	18	%	44	%	14	%	31	%

The HELOC portfolio holdings are regularly evaluated for potential OTTI. The HELOC securities credit enhancement is provided by a combination of excess spread, over-collateralization, subordination, and a note insurance policy provided by a monoline insurer. For the HELOC holdings, the rating is highly dependent upon the rating of the monoline insurance provider.

If a monoline insurer experiences a credit rating downgrade and it is determined that the monoline insurer may not be able to meet its obligations, the HELOC holdings guaranteed by that insurer are further evaluated based on the deal collateral and structure without the insurer guarantee. Potential losses are compared to the available total coverage provided by excess spread, over-collateralization and subordination for each bond to determine OTTI.

The following table provides the detail of securities portfolio losses. Securities losses in 2008 reflect mark-to-market (both credit and non-credit) impairment securities losses.

The following tables reflect investment securities credit losses recorded in earnings. The beginning balance represents the credit loss component for which OTTI occurred on debt securities in prior periods. The additions represent the first time a debt security was credit impaired or when subsequent credit impairments have occurred.

In conjunction with the restructuring of the investment securities portfolio, in the third quarter of 2009, we changed our intent to hold to maturity on $1.7 billion of securities included in the held-to-maturity classification and recorded mark-to-market losses, both credit and non-credit, on these securities in the income statement. These securities have experienced a decrease in the credit quality of the issuer or a significant increase in the risk-weight used for regulatory capital purposes.

Actual maturities may differ from contractual maturities because some borrowers have the right to call or prepay obligations with or without call penalties.

The Company currently invests funds in variable rate demand notes that have major bank liquidity agreements, municipal bonds and notes, commercial paper including money market instruments, auction rate securities and bank floating rate notes. Certain securities are subject to a hard-put option(s) where the principal amount is contractually assured by the issuer and any resistance to the exercise of these options would be deemed as a default by the issuer. Such a potential default would be reflected in the issuer’s respective credit rating, for which the Company maintains investment grade requirements pursuant to its corporate investment guidelines. While the Company believes its investments that have net unrealized losses are temporary, further declines in the value of these investments may be deemed other-than-temporary if the credit and capital markets were to continue to deteriorate in future periods. The Company does not have the intent to sell its investments and it is more likely than not that the Company will not have to sell the investments before the recovery of its cost basis. Therefore, the Company does not consider these investments to be other-than-temporarily impaired and will continue to monitor global market conditions to minimize the uncertainty of impairments in future periods.
