3M has a diversified marketable securities portfolio. Within this portfolio, asset-backed securities primarily include interests in automobile loans, credit cards and other asset-backed securities. 3M’s investment policy allows investments in asset-backed securities with minimum credit ratings of Aa3 by Moody’s Investors Service or AA- by Standard & Poor’s or Fitch Ratings or DBRS. Asset-backed securities must be rated by at least two of the aforementioned rating agencies, one of which must be Moody’s Investors Service or Standard & Poor’s. At December 31, 2017, all asset-backed security investments were in compliance with this policy. Approximately 90 percent of all asset-backed security investments were rated AAA or A-1+ by Standard & Poor’s and/or Aaa or P-1 by Moody’s Investors Service and/or AAA or F1+ by Fitch Ratings. Interest rate risk and credit risk related to the underlying collateral may impact the value of investments in asset-backed securities, while factors such as general conditions in the overall credit market and the nature of the underlying collateral may affect the liquidity of investments in asset-backed securities. 3M does not currently expect risk related to its holding in asset-backed securities to materially impact its financial condition or liquidity.
