Innovative tobacco products: Nu Mark participates in the e-vapor category and has developed and commercialized other innovative tobacco products.
In addition, Nu Mark sources the production of its e-vapor products through overseas contract manufacturing arrangements.
In 2013, Nu Mark introduced MarkTen e-vapor products.
In April 2014, Nu Mark acquired the e-vapor business of Green Smoke, Inc.  and its affiliates (“Green Smoke”), which began selling e-vapor products in 2009.
In 2017, Altria Group, Inc. ’s subsidiaries purchased certain intellectual property related to innovative tobacco products.
In December 2013, Altria Group, Inc. ’s subsidiaries entered into a series of agreements with Philip Morris International Inc.  (“PMI”) pursuant to which Altria Group, Inc. ’s subsidiaries provide an exclusive license to PMI to sell Nu Mark’s e-vapor products outside the United States, and PMI’s subsidiaries provide an exclusive license to Altria Group, Inc. ’s subsidiaries to sell two of PMI’s heated tobacco product platforms in the United States.
Further, in July 2015, Altria Group, Inc.  announced the expansion of its strategic framework with PMI to include a joint research, development and technology-sharing agreement.
Under this agreement, Altria Group, Inc. ’s subsidiaries and PMI will collaborate to develop e-vapor products for commercialization in the United States by Altria Group, Inc. ’s subsidiaries and in markets outside the United States by PMI.

Distribution, Competition and Raw Materials: Altria Group, Inc. ’s tobacco subsidiaries sell their tobacco products principally to wholesalers (including distributors), large retail organizations, including chain stores, and the armed services.
The market for tobacco products is highly competitive, characterized by brand recognition and loyalty, with product quality, taste, price, product innovation, marketing, packaging and distribution constituting the significant methods of competition.
Promotional activities include, in certain instances and where permitted by law, allowances, the distribution of incentive items, price promotions, product promotions, coupons and other discounts.
growth will be measured annually at the end of each fiscal year.
The remaining awarded units plus associated earned dividend equivalents will be settled, and the restricted period will lapse after the average of actual performance results for the three components of an environmental index measured as a percentage of target performance meets or exceeds 100 percent.
The environmental index will be measured annually at the end of each fiscal year.
If the performance criteria have not been met within four years of the date of grant, all associated units shall be forfeited.
The 2005 environmental restricted stock units met their target as of Dec.  31, 2006 and were settled in shares in February 2007.
The 2005 restricted stock units measured on EPS growth and all 2006 restricted stock units met their targets and will be settled in shares in the first quarter of 2008.
A summary of the status of our nonvested restricted stock units as of Dec.  31, 2007, and changes during the year ended Dec.  31, 2007 are as follows:
## Table 1 ##
The total aggregate intrinsic value of nonvested restricted stock units as of Dec.  31, 2007 was $1.0 million and the weighted average remaining contractual life was 2.2 years.
The total fair value and total intrinsic value of restricted stock units vested during the years ended Dec.  31, 2007, 2006 and 2005 were as follows:
## Table 2 ##
(a) Intrinsic value is calculated as the market price at vesting date less the fair value at grant date Performance Share Plan Awards (PSP) — Xcel Energy’s board of directors has granted performance share awards under the Xcel Energy Omnibus Incentive Plan approved by the shareholders in 2000 and under the Xcel Energy 2005 Omnibus Incentive Plan.
Both plans allow Xcel Energy to utilize various performance goals on the performance share awards granted.
The PSP has been entirely dependent on a single measure, the TSR and it is measured over a three-year period.
Xcel Energy’s TSR is compared to the TSR of other companies in the Edison Electric Institute’s Electrics Index.
At the end of the three-year period, potential payouts of the performance share awards range from 0 percent to 200 percent, depending on the Xcel Energy’s TSR compared to the peer group.
On Jan.  2, 2004, Xcel Energy granted 323,548 performance share awards under the Xcel Energy Omnibus Incentive Plan.
The grant-date market price used to calculate the TSR for this grant was $17.03.
The 2004 performance share awards met the TSR requirements as of Dec.  31, 2006 and were settled in shares and cash in February 2007.
For years ended Dec.  31, 2007, 2006 and 2005, the PSP awards granted were as follows:
## Table 3 ##
The 2005 performance share awards were granted under the Xcel Energy Omnibus Incentive Plan whereas the 2006 and 2007 awards were granted under the Xcel Energy 2005 Omnibus Incentive Plan.
The 2005 performance share awards met the TSR requirements as of Dec.  31, 2007 and will be settled in shares and cash in the first quarter of 2008.
Benefit Costs — The components of net periodic pension cost (credit) are:
## Table 4 ##
Pension costs include an expected return impact for the current year that may differ from actual investment performance in the plan.
The return assumption used for 2008 pension cost calculations will be 8.75 percent.
The cost calculation uses a market-related valuation of pension assets.
Xcel Energy uses a calculated value method to determine the market-related value of the plan assets.
The market-related value begins with the fair market value of assets as of the beginning of the year.
The market-related value is determined by adjusting the fair market value of assets to reflect the investment gains and losses (the difference between the actual investment return and the expected investment return on the market-related value) during each of the previous five years at the rate of 20 percent per year.
Xcel Energy also maintains noncontributory, defined benefit supplemental retirement income plans for certain qualifying executive personnel.
Benefits for these unfunded plans are paid out of Xcel Energy’s operating cash flows.
Defined Contribution Plans Xcel Energy maintains 401(k) plans that cover substantially all employees.
Total contributions to these plans were approximately $21.8 million in 2007, $18.3 million in 2006 and $19.6 million in 2005.
Postretirement Health Care Benefits Xcel Energy has a contributory health and welfare benefit plan that provides health care and death benefits to most Xcel Energy retirees.  ?
The former NSP discontinued contributing toward health care benefits for nonbargaining employees retiring after 1998 and for bargaining employees of NSP-Minnesota and NSP-Wisconsin who retired after 1999.  ?
Xcel Energy discontinued contributing toward health care benefits for former NCE nonbargaining employees retiring after June 30, 2003.  ?
Employees of NCE who retired in 2002 continue to receive employer-subsidized health care benefits.  ?
Nonbargaining employees of the former NSP who retired after 1998, bargaining employees of the former NSP who retired after 1999 and nonbargaining employees of NCE who retired after June 30, 2003, are eligible to participate in the Xcel Energy health care program with no employer subsidy.
In conjunction with the 1993 adoption of SFAS No.106 — ‘‘Employers’ Accounting for Postretirement Benefits Other Than Pension,’’ Xcel Energy elected to amortize the unrecognized accumulated postretirement benefit obligation (APBO) on a straight-line basis over 20 years.
Regulatory agencies for nearly all of Xcel Energy’s retail and wholesale utility customers have allowed rate recovery of accrued benefit costs under SFAS No.106.
The Colorado jurisdictional SFAS No.106 costs deferred during the transition period are being amortized to expense on a straight-line basis over the 15-year period from 1998 to 2012.
NSP-Minnesota also transitioned to full accrual accounting for SFAS No.106 costs, with regulatory differences fully amortized prior to 1997.
Plan Assets — Certain state agencies that regulate Xcel Energy’s utility subsidiaries also have issued guidelines related to the funding of SFAS No.106 costs.
SPS is required to fund SFAS No.106 costs for Texas and New Mexico jurisdictional amounts collected in rates and PSCo is required to fund SFAS No.106 costs in irrevocable external trusts that are dedicated to the payment of these postretirement benefits.
Also, a portion of the assets contributed on behalf of nonbargaining retirees has been funded into a sub-account of the Xcel Energy pension plans.
These assets are invested in a manner consistent with the investment strategy for the pension plan.
activities, revenues associated with processing solid waste into refuse-derived fuel and investments in rental housing projects that qualify for low-income housing tax credits.
To report income from continuing operations for regulated electric and regulated natural gas utility segments, Xcel Energy must assign or allocate all costs and certain other income.
In general, costs are: ·directly assigned wherever applicable; ·allocated based on cost causation allocators wherever applicable;and .
allocated based on a general allocator for all other costs not assigned by the above two methods.
The accounting policies of the segments are the same as those described in Note 1 to the consolidated financil statements.
