NOTES to CONSOLIDATED FINANCIAL STATEMENTS 62 On March 28, 2003, the governance, compensation and nominating committee of Xcel Energy’s board of directors granted restricted stock units and performance shares under the Xcel Energy Inc.
Omnibus Incentive Plan approved by the shareholders in 2000.
Restrictions on the restricted stock units lapse upon the achievement of a 27-percent total shareholder return (TSR) for 10 consecutive business days and other criteria relating to Xcel Energy’s common equity ratio.
Under no circumstances will the restrictions lapse until one year after the grant date.
TSR is measured using the market price per share of Xcel Energy common stock, which at the grant date was $12.93, plus common dividends declared after grant date.
The TSR was met in the fourth quarter of 2003, and approximately $31 million of compensation expense was recorded at Dec.  31, 2003.
The remaining cost of $10 million related to the 2003 restricted stock units was recorded in the first quarter of 2004.
In January 2004, Xcel Energy’s board of directors approved the repurchase of up to 2.5 million shares of common stock to fulfill the requirements of the restricted stock unit exercise.
On March 29, 2004, the restricted stock units lapsed, and Xcel Energy issued approximately 1.6 million shares of common stock.
On Dec.  9, 2003, the governance, compensation and nominating committee of Xcel Energy’s board of directors approved restricted stock units and performance shares under the Xcel Energy Inc.
Omnibus Incentive Plan.
On Jan.  2, 2004, Xcel Energy granted 836,186 restricted stock units and performance shares.
The grant-date market price used to calculate the TSR for this grant is $17.03.
No expense has been recorded for the 2004 restricted stock units as it is not currently probable they will be earned.
On Dec.  14, 2004, the governance, compensation and nominating committee of Xcel Energy’s board of directors approved restricted stock units and performance shares under the Xcel Energy Inc.
Omnibus Incentive Plan.
On Jan.  1, 2005, Xcel Energy granted 843,251 restricted stock units and performance shares.
The grant-date market price used to calculate the TSR for this grant is $18.10.
Xcel Energy applies Accounting Principles Board Opinion No.25 – “Accounting for Stock Issued to Employees” in accounting for stock-based compensation and, accordingly, no compensation cost is recognized for the issuance of stock options, as the exercise price of the options equals the fair-market value of Xcel Energy’s common stock at the date of grant.
In December 2002, the FASB issued SFAS No.148 – “Accounting for Stock-Based Compensation – Transition and Disclosure,” amending SFAS No.123 to provide alternative methods of transition for a voluntary change to the fair-value-based method of accounting for stock-based employee compensation, and requiring disclosure in both annual and interim Consolidated Financial Statements about the method used and the effect of the method used on results.
The pro forma impact of applying SFAS No.148 is as follows at Dec.  31:

Energy Source Statistics
## Table 1 ##
(a) This category includes wind energy de-bundled from RECs and also includes Windsource RECs.
Xcel Energy uses RECs to meet or exceed state resource requirements and may sell surplus RECs.
(b) Includes energy from other sources, including solar, biomass, oil and refuse.
Distributed generation from the Solar*Rewards program is not included, and was approximately 0.198, 0.152, and 0.146 net million KWh for 2013, 2012 and 2011, respectively NATURAL GAS UTILITY OPERATIONS Overview The most significant developments in the natural gas operations of the utility subsidiaries are continued volatility in natural gas market prices, uncertainty regarding political and regulatory developments that impact hydraulic fracturing, safety requirements for natural gas pipelines and the continued trend of declining use per customer, as a result of improved building construction technologies, higher appliance efficiencies and conservation.
From 2000 to 2013, average annual sales to the typical residential customer declined 17 percent and the typical small commercial and industrial customer declined 11 percent on a weather-normalized basis.
Although wholesale price increases do not directly affect earnings because of natural gas cost-recovery mechanisms, high prices can encourage further efficiency efforts by customers.
The Pipeline and Hazardous Materials Safety Administration Pipeline Safety Act — The Pipeline Safety, Regulatory Certainty, and Job Creation Act, signed into law in January 2012 (Pipeline Safety Act) requires additional verification of pipeline infrastructure records by pipeline owners and operators to confirm the maximum allowable operating pressure of lines located in high consequence areas or more-densely populated areas.
The DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) will require operators to re-confirm the maximum allowable operating pressure if records are inadequate.
This process could cause temporary or permanent limitations on throughput for affected pipelines.
In addition, the Pipeline Safety Act requires PHMSA to issue reports and develop new regulations including: requiring use of automatic or remote-controlled shut-off valves; requiring testing of certain previously untested transmission lines; and expanding integrity management requirements.
The Pipeline Safety Act also raises the maximum penalty for violating pipeline safety rules to $2 million per day for related violations.
While Xcel Energy cannot predict the ultimate impact Pipeline Safety Act will have on its costs, operations or financial results, it is taking actions that are intended to comply with the Pipeline Safety Act and any related PHMSA regulations as they become effective.
PSCo can generally recover costs to comply with the transmission and distribution integrity management programs through the PSIA rider.
NSP-Minnesota Public Utility Regulation Summary of Regulatory Agencies and Areas of Jurisdiction — Retail rates, services and other aspects of NSP-Minnesota’s retail natural gas operations are regulated by the MPUC and the NDPSC within their respective states.
The MPUC has regulatory authority over security issuances, certain property transfers, mergers with other utilities and transactions between NSP-Minnesota and its affiliates.
In addition, the MPUC reviews and approves NSP-Minnesota’s natural gas supply plans for meeting customers’ future energy needs.
NSP-Minnesota is subject to the jurisdiction of the FERC with respect to certain natural gas transactions in interstate commerce.
NSP-Minnesota is subject to the DOT, the Minnesota Office of Pipeline Safety, the NDPSC and the SDPUC for pipeline safety compliance, including pipeline facilities used in electric utility operations for fuel deliveries.
Pension Benefits Xcel Energy has several noncontributory, defined benefit pension plans that cover almost all employees.
Generally, benefits are based on a combination of years of service, the employee’s average pay and, in some cases, social security benefits.
Xcel Energy’s policy is to fully fund into an external trust the actuarially determined pension costs recognized for ratemaking and financial reporting purposes, subject to the limitations of applicable employee benefit and tax laws.
In addition to the qualified pension plans, Xcel Energy maintains a supplemental executive retirement plan (SERP) and a nonqualified pension plan.
The SERP is maintained for certain executives that were participants in the plan in 2008, when the SERP was closed to new participants.
The nonqualified pension plan provides unfunded, nonqualified benefits for compensation that is in excess of the limits applicable to the qualified pension plans, with distributions funded by Xcel Energy’s consolidated operating cash flows.
The total obligations of the SERP and nonqualified plan as of Dec.  31, 2016 and 2015 were $43.5 million and $41.8 million, respectively.
In 2016 and 2015, Xcel Energy recognized net benefit cost for financial reporting for the SERP and nonqualified plans of $7.9 million and $9.5 million, respectively.
In 2016, Xcel Energy established rabbi trusts to provide partial funding for future distributions of the SERP and its deferred compensation plan, supplemented by Xcel Energy’s consolidated operating cash flows as determined necessary.
For more information regarding the funding of rabbi trusts, see Note 11 to the consolidated financial statements.
Also in 2016, Xcel Energy amended the deferred compensation plan to provide eligible participants the ability to diversify deferred settlements of equity awards, other than time-based equity awards, into various fund options.
Xcel Energy bases the investment-return assumption on expected long-term performance for each of the investment types included in its pension asset portfolio.
Xcel Energy considers the historical returns achieved by its asset portfolio over the past 20-year or longer period, as well as the long-term return levels projected and recommended by investment experts.
Xcel Energy continually reviews its pension assumptions.
The pension cost determination assumes a forecasted mix of investment types over the long-term.  ?
Investment returns in 2016 were below the assumed level of 6.87 percent; ?
Investment returns in 2015 were below the assumed level of 7.09 percent; ?
Investment returns in 2014 were above the assumed level of 7.05 percent; and ?
In 2017, Xcel Energy’s expected investment-return assumption is 6.87 percent.
The assets are invested in a portfolio according to Xcel Energy’s return, liquidity and diversification objectives to provide a source of funding for plan obligations and minimize the necessity of contributions to the plan, within appropriate levels of risk.
The principal mechanism for achieving these objectives is the projected allocation of assets to selected asset classes, given the long-term risk, return, and liquidity characteristics of each particular asset class.
There were no significant concentrations of risk in any particular industry, index, or entity.
Market volatility can impact even well-diversified portfolios and significantly affect the return levels achieved by pension assets in any year.
The following table presents the target pension asset allocations for Xcel Energy at Dec.  31 for the upcoming year:
## Table 2 ##
Xcel Energy’s ongoing investment strategy is based on plan-specific investment recommendations that seek to minimize potential investment and interest rate risk as a plan’s funded status increases over time.
The investment recommendations result in a greater percentage of long-duration fixed income securities being allocated to specific plans having relatively higher funded status ratios and a greater percentage of growth assets being allocated to plans having relatively lower funded status ratios.
The aggregate projected asset allocation presented in the table above for the master pension trust results from the plan-specific strategies.
Earnings Adjusted for Certain Items (Ongoing Earnings and Ongoing Diluted EPS) GAAP diluted EPS reflects the potential dilution that could occur if securities or other agreements to issue common stock (i. e. , common stock equivalents) were settled.
The weighted average number of potentially dilutive shares outstanding used to calculate Xcel Energy Inc. ’s diluted EPS is calculated using the treasury stock method.
Ongoing earnings reflect adjustments to GAAP earnings (net income) for certain items.
Ongoing diluted EPS is calculated by dividing the net income or loss of each subsidiary, adjusted for certain items, by the weighted average fully diluted Xcel Energy Inc.  common shares outstanding for the period.
Ongoing diluted EPS for each subsidiary is calculated by dividing the net income or loss of such subsidiary, adjusted for certain items, by the weighted average fully diluted Xcel Energy Inc.  common shares outstanding for the period.
We use these non-GAAP financial measures to evaluate and provide details of Xcel Energy’s core earnings and underlying performance.
We believe these measurements are useful to investors to evaluate the actual and projected financial performance and contribution of our subsidiaries.
For the year ended Dec.  31, 2017, Xcel Energy recognized an estimated one-time, non-cash, income tax expense of approximately $23 million for net excess deferred tax assets which may not be recovered from customers or not attributable to regulated operations, increased valuation allowances, etc.
due to the enactment of the TCJAin December 2017.
For the year ended Dec.  31, 2018, there were no such adjustments to GAAP earnings and therefore GAAP earnings equal ongoing earnings.
See Note 7 to the consolidated financial statements for further information.
