Cash Flows from Financing Activities: 

 

Total debt at December 31, 2005, was $2.381 billion, down from $2.821 billion at year-end 2004, with the decrease primarily attributable to the retirement of $400 million in medium-term notes. There were no new long-term debt issuances in 2005. In 2005, the cash flow decrease in net short-term debt of $258 million includes the portion of short-term debt with original maturities of 90 days or less. The repayment of debt of $656 million primarily related to the retirement of $400 million in medium-term notes and commercial paper retirements. Proceeds from debt of $429 million primarily related to commercial paper issuances. Total debt was 19% of total capital (total capital is defined as debt plus equity), compared with 21% at year-end 2004.

 

Debt securities, including the Company’s shelf registration, its medium-term notes program, dealer remarketable securities and Convertible Note, are all discussed in more detail in Note 8 to the Consolidated Financial Statements. 3M has a shelf registration and medium-term notes program through which $1.5 billion of medium-term notes may be offered. In 2004, the Company issued approximately $62 million in debt securities under its medium-term notes program. No debt was issued under this program in 2005. The medium-term notes program and shelf registration have remaining capacity of approximately $1.438 billion. The Company’s $350 million of dealer remarketable securities (classified as current portion of long-term debt) were remarketed for one year in December 2005. In addition, the Company has Convertible Notes with a book value of $539 million at December 31, 2005.



The next put option date for these Convertible Notes is November 2007, thus at year-end 2005 this debt is classified as long-term debt. At December 31, 2005, the dealer remarketable securities and $62 million of medium-term notes are classified as current portion of long-term debt as the result of put provisions associated with these debt instruments.
