Company (“DP&L”), which it owns through DPL Inc.  (“DPL”), the parent company of DP&L.
IPL generates, transmits, distributes and sells electricity to approximately 470,000 customers in the city of Indianapolis and neighboring areas within the state of Indiana.
IPL owns and operates four generating stations.
Two of the generating stations are primarily coal-fired stations.
The third station has a combination of units that use coal (base load capacity) and natural gas and/or oil (peaking capacity) for fuel to produce electricity.
The fourth station is a small peaking station that uses gas-fired combustion turbine technology for the production of electricity.
IPL’s gross electric generation capacity is 3,699 MW.
Approximately 45% of IPL’s coal is provided by one supplier with which IPL has long-term contracts.
A key driver for the business is tariff recovery for environmental projects through the rate adjustment process.
IPL’s customers include residential, industrial, commercial and all other which made up 33%, 13%, 36% and 6%, respectively, of North America Utilities revenue for 2011.
The remaining 12% of North America Utilities revenue is from DPL.
DP&L generates, transmits, distributes and sells electricity to more than 500,000 customers in a 6,000 square mile area of West Central Ohio.
DP&L, with certain other Ohio utilities and their affiliates, commonly owns seven coal-fired electric generating facilities and numerous transmission facilities.
DP&L also has one wholly-owned coal-fired plant.
DP&L is affiliated with DPL Energy, LLC (“DPLE”) which owns peaking generation units located in Ohio and Indiana.
DP&L’s wholly-owned plants and share of the capacity of its jointly-owned plants and DPLE’s wholly-owned peaking units aggregates to approximately 3,817 MW.
During the period November 28, 2011 through December 31, 2011, approximately 80% of DP&L’s coal was provided by four suppliers and DP&L has long-term contracts with three of them.
DP&L’s customers include residential, commercial, industrial and governmental, which make up 67%, 21% and 12%, respectively, of DP&L’s revenue for the period after acquisition in November 2011.

(1) IPL plants: Eagle Valley, Georgetown, Harding Street and Petersburg.
(2) DP&L wholly-owned plants: Hutchings, Tait Units 1-3 and diesels, Yankee Street, Yankee Solar, Monument and Sidney.
DP&L jointly-owned plants: Beckjord Unit 6, Conesville Unit 4, East Bend Unit 2, Killen, Miami Fort Units 7 & 8, Stuart and Zimmer.
In addition to the above, DP&L, also owns a 4.9% equity ownership in OVEC, an electric generating company.
OVEC has two plants in Cheshire, Ohio and Madison, Indiana with a combined generation capacity of approximately 2,655 MW.
DP&L’s share of this generation capacity is approximately 111 MW.
DPLE plants: Tait Units 4-7 and Montpelier Units 1-4.
Distribution

At January 31, 2015, there was $84 million of unrecognized compensation expense related to nonvested time-based share awards that we expect to recognize over a weighted-average period of 1.9 years.
Earnings per Share We compute our basic earnings per share based on the weighted-average number of common shares outstanding, and our diluted earnings per share based on the weighted-average number of common shares outstanding adjusted by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued.
Potentially dilutive securities include stock options, nonvested share awards and shares issuable under our employee stock purchase plan.
Nonvested market-based share awards and nonvested performance-based share awards are included in the average diluted shares outstanding each period if established market or performance criteria have been met at the end of the respective periods.
At January 31, 2015, options to purchase 17.3 million shares of common stock were outstanding as follows (shares in millions):
## Table 2 ##
The computation of dilutive shares outstanding excludes the out-of-the-money stock options because such outstanding options' exercise prices were greater than the average market price of our common shares and, therefore, the effect would be antidilutive (i. e. , including such options would result in higher earnings per share).
The following table presents a reconciliation of the numerators and denominators of basic and diluted earnings per share in fiscal 2015, 2014 and 2013 (11-month):
## Table 3 ##
(1) The calculation of diluted loss per share for fiscal 2013 (11-month) does not include potentially dilutive securities because their inclusion would be antidilutive (i. e. , reduce the net loss per share).
Repurchase of Common Stock In June 2011, our Board of Directors authorized a $5.0 billion share repurchase program.
The June 2011 program replaced our prior $5.5 billion share repurchase program authorized in June 2007.
There is no expiration date governing the period over which we can repurchase shares under the June 2011 share repurchase program.
The following table presents the amount and cost of shares we repurchased and retired in fiscal 2015, 2014 and 2013 (11- month) under the June 2011 program and the June 2007 program ($ and shares in millions):
renewable energy programs, and other liabilities.
Retirement benefits are also excluded from the table above.
For details related to benefit payments, see Note 12, Retirement Benefits.
Off-Balance-Sheet Arrangements: CMS Energy, Consumers, and certain of their subsidiaries also enter into various arrangements in the normal course of business to facilitate commercial transactions with third parties.
These arrangements include indemnities, surety bonds, letters of credit, and financial and performance guarantees.
Indemnities are usually agreements to reimburse a counterparty that may incur losses due to outside claims or breach of contract terms.
The maximum payment that could be required under a number of these indemnity obligations is not estimable; the maximum obligation under indemnities for which such amounts were estimable was $150 million at December 31, 2014.
While CMS Energy and Consumers believe it is unlikely that they will incur any material losses related to indemnities they have not recorded as liabilities, they cannot predict the impact of these contingent obligations on their liquidity and financial condition.
For additional details on these and other guarantee arrangements, see Note 4, Contingencies and Commitments – Guarantees.
Capital Expenditures: Over the next five years, CMS Energy and Consumers expect to make substantial capital investments.
CMS Energy and Consumers may revise their forecasts of capital expenditures periodically due to a number of factors, including environmental regulations, business opportunities, market volatility, economic trends, and the ability to access capital.
Presented in the following table are CMS Energy’s and Consumers’ estimated capital expenditures, including lease commitments, for 2015 through 2019:
## Table 4 ##
OUTLOOK Several business trends and uncertainties may affect CMS Energy’s and Consumers’ financial condition and results of operations.
These trends and uncertainties could have a material impact on CMS Energy’s and Consumers’ consolidated income, cash flows, or financial position.
For additional details regarding these and other uncertainties, see Forward-Looking Statements and Information; Item 1A.
Risk Factors; and Note 4, Contingencies and Commitments.
CONSUMERS ELECTRIC UTILITY AND GAS UTILITY BUSINESS OUTLOOK AND UNCERTAINTIES Energy Optimization Plan: The 2008 Energy Law requires Consumers to achieve energy savings equivalent to annual usage reduction targets through at least 2015.
The targets increase annually, with the goal of achieving cumulative reductions of 5.6 percent in customers’ electricity use and 3.9 percent in customers’ natural gas use by December 31, 2015.
Under its energy optimization plan, Consumers provides its customers with incentives to reduce usage by offering energy audits, rebates and discounts on purchases of highly efficient appliances, and other incentives and programs.
At December 31, 2014, Consumers had achieved cumulative reductions of 6.0 percent in customers’ electricity use and 4.0 percent in customers’ natural gas use; the savings results will be certified by a third party.
Consumers estimates that, through its gas and electric energy optimization programs, its customers realized $280 million in energy savings during 2014.
