Other Ameren sponsors a 401(k) plan for eligible employees.
The Ameren 401(k) plan covered all eligible employees at December 31, 2015.
The plan allows employees to contribute a portion of their compensation in accordance with specific guidelines.
Ameren matches a percentage of the employee contributions up to certain limits.
The following table presents the portion of the matching contribution to the Ameren 401(k) plan attributable to the continuing operations for each of the Ameren Companies for the years ended December 31, 2015, 2014, and 2013:
## Table 0 ##
(a) Includes amounts for Ameren registrant and nonregistrant subsidiaries.
NOTE 12 – STOCK-BASED COMPENSATION The 2014 Incentive Plan is Ameren’s long-term stock compensation plan for eligible employees and directors.
The 2006 Incentive Plan was replaced prospectively for new grants beginning in April 2014.
The 2014 Incentive Plan provides for a maximum of 8 million common shares to be available for grant to eligible employees and directors.
To the extent that the issuance of a share that is subject to an outstanding award under the 2006 Incentive Plan would cause Ameren to exceed the maximum authorized shares under the 2006 Incentive Plan, the issuance of that share will take place under the 2014 Incentive Plan.
This will reduce the maximum number of shares that may be granted under the 2014 Incentive Plan.
The 2014 Incentive Plan awards may be stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance share units, cash-based awards, and other stock-based awards.
A summary of nonvested shares at December 31, 2015, and changes during the year ended December 31, 2015, under the 2006 Incentive Plan and the 2014 Incentive Plan are presented below:
## Table 1 ##
(a) Includes performance share units (share units) granted to certain executive and nonexecutive officers and other eligible employees in 2015 under the 2014 Incentive Plan.
(b) Includes share units granted in 2013 that vested as of December 31, 2015, that were earned pursuant to the terms of the award grants.
Also includes share units that vested due to attainment of retirement eligibility by certain employees.
Actual shares issued for retirement-eligible employees will vary depending on actual performance over the three-year measurement period.
Ameren recorded compensation expense of $19 million, $19 million, and $20 million for the years ended December 31, 2015, 2014, and 2013, respectively, and a related tax benefit of $7 million, $7 million, and $8 million for the years ended December 31, 2015, 2014, and 2013, respectively.
Ameren settled performance share units of $27 million, $33 million, and $11 million for the years ended December 31, 2015, 2014, and 2013.
There were no significant compensation costs capitalized related to the performance share units during the years ended December 31, 2015, 2014, and 2013.
As of December 31, 2015, total compensation cost of $21 million related to nonvested awards not yet recognized is expected to be recognized over a weighted-average period of 23 months.
Performance Share Units A share unit vests and entitles an employee to receive shares of Ameren common stock (plus accumulated dividends) if, at the end of the three-year performance period, certain specified performance or market conditions have been met and if the individual remains employed by Ameren through the required vesting period.
The exact number of shares issued pursuant to a share unit varies from 0% to 200% of the target award, depending on actual company performance relative to the performance goals.
The vesting period for share units awarded in 2015 extended beyond the three-year performance period to the payout date, while the vesting period for share units awarded in 2013 and 2014 matched the three-year performance period.
Issuer Purchases of Equity Securities The following table provides information regarding purchases of our common stock that were made by us during the fourth quarter of 2011.
## Table 2 ##
(1) In May 2010, our Board of Directors approved a $3.5 billion share repurchase program.
We completed this program in the fourth quarter of 2011.
In total, we repurchased 49.2 million common shares for $3.5 billion, or $71.18 per share, under this program.
(2) During the fourth quarter of 2011, we repurchased 672,326 shares from company employees for the payment of personal income tax withholdings resulting from restricted stock vesting and stock option exercises.
Such repurchases are in addition to the $3.5 billion repurchase program.
Under the Devon Energy Corporation Incentive Savings Plan (the “Plan”), eligible employees may purchase shares of our common stock through an investment in the Devon Stock Fund (the “Stock Fund”), which is administered by an independent trustee, Fidelity Management Trust Company.
Eligible employees purchased approximately 45,000 shares of our common stock in 2011, at then-prevailing stock prices, that they held through their ownership in the Stock Fund.
We acquired the shares of our common stock sold under the Plan through open-market purchases.
We filed a registration statement on Form S-8 on January 26, 2012 registering any offers and sales of interests in the Plan or the Stock Fund and of the underlying shares of our common stock purchased by Plan participants after that date.
Similarly, under the Devon Canada Corporation Savings Plan (the “Canadian Plan”), eligible Canadian employees may purchase shares of our common stock through an investment in the Canadian Plan, which is administered by an independent trustee, Sun Life Assurance Company of Canada.
Eligible Canadian employees purchased approximately 9,000 shares of our common stock in 2011, at then-prevailing stock prices, that they held through their ownership in the Canadian Plan.
We acquired the shares sold under the Canadian Plan through open-market purchases.
These shares and any interest in the Canadian Plan were offered and sold in reliance on the exemptions for offers and sales of securities made outside of the U. S. , including under Regulation S for offers and sales of securities to employees pursuant to an employee benefit plan established and administered in accordance with the law of a country other than the U. S.
CECONY’s gas sales and deliverr the last five years were:
## Table 3 ##
For further discussion of the company’s gas operating revenues and its gas results, see “Results of Operations” in Item 7.
For additional segment information, see Note N to the financial statements in Item 8.
Gas Peak Demand The gas peak demand for firm service customers in CECONY’s service area occurs during the winter heating season.
The daily peak day demand during the winter 2009/2010 (through January 31, 2010) occurred on January 3, 2010 when the demand reached 872 mdths.
The 2009/2010 winter demand included an estimated 502 mdths for CECONY’s full-service customers and 370 mdths for customers participating in its gas retail access program.
“Design weather” for the gas system is a standard to which the actual peak demand is adjusted for evaluation and planning purposes.
The company estimates that under design weather conditions the 2010/2011 service area peak demand will be 1,146 mdths, including an estimated 661 mdths for its full-service customers and 485 mdths for its retail access customers.
The company forecasts average annual growth of the peak gas demand over the next five years at design conditions to be approximately 1.0 percent in its service area.
The forecasted peak demand at design conditions does not include gas used by interruptible gas customers or in generating stations (electricity and steam).
The company continues to monitor the potential impact on customer demand from the continuing difficult economic conditions.
Gas Supply CECONY and O&R have combined their gas requirements, and contracts to meet those requirements, into a single portfolio.
The combined portfolio is administered by, and related management services are provided by, CECONY (for itself and as agent for O&R) and costs are allocated between the Utilities in accordance with provisions approved by the NYSPSC.
See Note S to the financial statements in Item
representing more than 50% of the aggregate commitments of all lenders under the New Facility.
Borrowings under the New Facility bear interest at an annual rate of LIBOR plus a margin, currently 125 bps, linked to our credit rating.
The interest rate under the New Facility at December 31, 2011 was 1.77%.
The New Facility contains various affirmative and negative covenants, including the requirement for us to maintain, at the end of each fiscal quarter, a ratio of net debt for borrowed money to adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) in respect of the previous 12-month period of not more than 3.25 to 1.
We have complied with this covenant at all times.
The New Facility provides us with access to approximately $80 million of additional borrowings compared to the old Facility.
The margin added to the annual rate of LIBOR is currently 100 bps higher than the old Facility.
Such increase has not caused a material change to our cost of borrowing.
As of December 31, 2011 we had total borrowings under the New Facility of $157.5 million.
The amount which we are able to draw down on under the Agreement is limited by financial covenants as described in more detail below.
At December 31, 2011 we had a remaining overall borrowing capacity of $1,028.0 million.
However, our drawdown capacity on the New Facility was limited to $784.5 million based on existing balances outstanding under the Facility at December 31, 2011.
The Company did not have any letters of credit outstanding under the New Facility as of December 31, 2011.
The Facility contains the most restrictive covenant of all of our debt requiring us to maintain, at the end of each fiscal quarter, a ratio of net debt for borrowed money to adjusted EBITDA in respect of the previous 12-month period of not more than 3.25 to 1.
At December 31, 2011 and 2010 we were in compliance with all financial and other covenants.
At December 31, 2011 our Net Debt/adjusted EBITDA(1) was 1.42 to 1 as defined by the debt agreements, well below the financial covenants of existing outstanding debt.
Failure to comply with the financial and other covenants under these agreements would constitute default and would allow the lenders to accelerate the maturity of all indebtedness under the related agreement.
If such acceleration were to occur, we would not have sufficient liquidity available to repay the indebtedness.
We would likely have to seek amendments under the agreements for relief from the financial covenants or repay the debt with proceeds from the issuance of new debt or equity, and/or asset sales, if necessary.
We may be unable to amend the agreements or raise sufficient capital to repay such obligations in the event the maturities are accelerated.
(1) Adjusted EBITDA and Net Debt, which are non-GAAP measures used for these covenants, are calculated in accordance with the definition in the debt agreements.
In this context, these measures are used solely to provide information on the extent to which we are in compliance with debt covenants and may not be comparable to adjusted EBITDA and Net Debt used by other companies.
Reconciliations of adjusted EBITDA to net income and net debt to total debt are as follows:
