Fixed income commingled funds – Some of the fixed income securities are held in commingled funds, which have daily net asset values derived from the underlying securities; these are classified as Level 2 investments.
Real estate funds – The value of the real estate funds is reported by the fund manager and is based on a valuation of the underlying properties.
Inputs used in the valuation include items such as cost, discounted future cash flows, independent appraisals and market based comparable data.

Concentration of Credit Risk: We evaluated our pension plans’ asset portfolios for the existence of significant concentrations of credit risk as of March 31, 2011.
Types of concentrations that were evaluated include investment funds that represented 10% or more of the pension plans’ net assets.
As of March 31, 2011, 11% of our plan assets is comprised of Bartram International Fund, which holds only actively traded stock.
Other Defined Benefit Plans Under various U. S.  bargaining unit labor contracts, we make payments into multi-employer pension plans established for union employees.
We are liable for a proportionate part of the plans’ unfunded vested benefit upon our withdrawal from the plan; however, information regarding the relative position of each employer with respect to the actuarial present value of accumulated benefits and net assets available for benefits is not available.
Contributions to the plans and amounts accrued were not material for the years ended March 31, 2011, 2010 and 2009.

Segments and Related Information The regulated electric utility operating results of NSP-Minnesota, NSP-Wisconsin, PSCo and SPS, as well as the regulated natural gas utility operating results of NSP-Minnesota, NSP-Wisconsin, and PSCo are each separately and regularly reviewed by Xcel Energy’s chief operating decision maker.
Xcel Energy evaluates performance by each utility subsidiary based on profit or loss generated from the product or service provided.
These segments are managed separately because the revenue streams are dependent upon regulated rate recovery, which is separately determined for each segment.
Given the similarity of the regulated electric utility operations of its utility subsidiaries, and the similarity of the regulated natural gas utility operations its utility subsidiaries, Xcel Energy has the following reportable segments: regulated electric utility, regulated natural gas utility and all other.  ?
Xcel Energy’s regulated electric utility segment generates, transmits and distributes electricity in Minnesota, Wisconsin, Michigan, North Dakota, South Dakota, Colorado, Texas and New Mexico.
In addition, this segment includes sales for resale and provides wholesale transmission service to various entities in the United States.
Regulated electric utility also includes commodity trading operations.
In October 2005, SPS reached a definitive agreement to sell its delivery system operations in Oklahoma, Kansas and a small portion of Texas to Tri-County Electric Cooperative.
Effective July 31, 2006, SPS completed the sale to Tri-County Electric Cooperative for $24.5 million and a gain of $6.1 million was recognized.
SPS now provides wholesale service to Tri-County Electric Cooperative.  ?
Xcel Energy’s regulated natural gas utility segment transports, stores and distributes natural gas primarily in portions of Minnesota, Wisconsin, North Dakota, Michigan and Colorado.
Revenues from operating segments not included above are below the necessary quantitative thresholds and are therefore included in the all other category.
Those primarily include steam revenue, appliance repair services, nonutility real estate
