Short-Term and Long-Term Debt

Short-Term Debt. Total short-term debt outstanding as of December 31, 2010, was $14.4 million ($7.1 million at December 31, 2009) and consisted of long-term debt due within one year and notes payable. (See ALLETE consolidated balance sheet.)

As of December 31, 2010, we had bank lines of credit aggregating $154.0 million ($157.0 million at December 31, 2009), the majority of which expire in January 2012. We expect to enter into new bank lines of credit during 2011 to replace the expiring facility. These bank lines of credit are available to provide short-term bank loans and credit support for commercial paper. At December 31, 2010, $1.0 million ($69.2 million at December 31, 2009) was drawn on our lines of credit leaving a $153.0 million balance available for use ($87.8 million at December 31, 2009). In December 2009, we drew $65.0 million on our $150.0 million syndicated revolving credit facility to temporarily fund the purchase of the 250 kV DC transmission line. In February 2010, we issued $80.0 million of First Mortgage Bonds (Bonds) (see Long-Term Debt, below). We used the proceeds from the sale of the Bonds to pay off the outstanding amount drawn on the line, resulting in the $65.0 million borrowing under our line of credit being classified as long-term debt at December 31, 2009.

On November 12, 2009, BNI Coal replaced a $6.0 million Promissory Note and Supplement (Line of Credit) with CoBANK, ACB with a $3.0 million Line of Credit and a $3.0 million term loan with CoBANK, ACB. The Line of Credit was renewed on December 22, 2010, and now expires on November 20, 2012. The Line of Credit is being used for general corporate purposes. As of December 31, 2010, $1.0 million was drawn on the Line of Credit. The $3.0 million term loan has a fixed interest rate of 5.19 percent and is payable in 28 equal quarterly installments commencing January 20, 2010, and ending on October 20, 2016.

Long-Term Debt. The aggregate amount of long-term debt maturing during 2011 is $13.4 million ($3.3 million in 2012; $73.9 million in 2013; $19.5 million in 2014; $16.3 million in 2015; and $658.6 million thereafter). Substantially all of our electric plant is subject to the lien of the mortgages collateralizing various First Mortgage Bonds. The mortgages contain non-financial covenants customary in utility mortgages, including restrictions on our ability to incur liens, dispose of assets, and merge with other entities.

In February 2010, we issued $80.0 million in principal amount of unregistered First Mortgage Bonds in the private placement market in three series as follows:

Issue Date	Maturity	Principal Amount	Interest Rate
February 17, 2010	April 15, 2021	$15 Million	4.85%

Expenditures for additions, significant replacements, improvements and major plant overhauls are capitalized; maintenance and repair costs are expensed as incurred. Gains or losses on non-rate base property, plant and equipment are recognized when they are retired or otherwise disposed. When regulated utility property, plant and equipment are retired or otherwise disposed, no gain or loss is recognized in accordance with the accounting standards for Regulated Operations. Our Regulated Operations capitalize AFUDC, which includes both an interest and equity component. AFUDC represents the cost of both debt and equity funds used to finance utility plant additions during construction periods. AFUDC amounts capitalized are included in rate base and are recovered from customers as the related property is depreciated. However, the MPUC has approved current cost recovery for several large capital projects recently, resulting in lower recognition of AFUDC. (See Note 3.

The amended guidance also requires that in the Level 3 reconciliation, the information about purchases, sales, issuances, and settle ments be disclosed separately on a gross basis rather than as one net number. The guidance for the Level 1 and 2 disclosures was adopted January#160;1,#160;2010, and did not have an impact on our consolidated financial position, results of operations or cash flows. The guidance for the activity in Level 3 disclosures is effective January 1, 2011, and is not expected to have an impact on our consolidated financial position, results of operations or cash flows as the amended guidance provides only disclosure requirements./font/divdiv style="DISPLAY: block; TEXT-INDENT: 0pt"br //divdiv style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"font style="DISPLAY: inline; FONT-STYLE: italic"Variable Interest Entities (VIEs)./font In June 2009, the FASB issued authoritative guidance changing the approach to determine a VIE mp;#8217;s primary beneficiary and requiring ongoing assessments of whether an enterprise is the primary beneficiary of a VIE.

Each of us must provide our own financing and is obligated to pay our ownership share of operating costs. Our share of direct operating expenses of Boswell Unit 4 is included in operating expense on our consolidated statement of income.
