Xcel Energy’s management believes that ongoing earnings provide a meaningful comparison of earnings results and is representative of Xcel Energy’s fundamental core earnings power. Xcel Energy’s management uses ongoing earnings internally for financial planning and analysis, for reporting of results to the Board of Directors, and when communicating its earnings outlook to
analysts and investors.

Dividend Flexibility
Annual dividend growth target range of 4% – 6% — No dividend payout range target — Dividend growth may periodically exceed EPS growth
Dividend considerations — Providing a competitive dividend yield — Capital investment growth opportunities — Balance sheet and credit ratings — Projected cash generation and requirements
Dividend decisions are the responsibility of the Board of Directors
In February 2014, Xcel Energy’s Board of Directors increased the dividend 8 cents per share on an annual basis, or 7.1%

Minnesota Multi-Year Electric Rate Case
* In July 2014, the Minnesota Department of Commerce (DOC) recommended a cost disallowance of approximately $71.5 million on a Minnesota jurisdictional basis which equates to a total NSP System disallowance of approximately $94 million. This would reduce NSP-Minnesota’s revenue requirement by approximately $10.2 million in 2015. ** Adjustment relates to timing differences and/or methodology of accelerating amortization of the excess depreciation reserve over three years.
