Commitments and Contingencies Legal Proceedings On March 16, 2007, PDL BioPharma, Inc. , or PDL, filed a civil action against Alexion in the U. S.  District Court for the District of Delaware.
PDL claims willful infringement by Alexion of PDL patents due to sales of Soliris.
PDL seeks unspecified damages, but no less than a reasonable royalty, plus attorney’s fees.
Alexion has denied PDL's claims.
In addition, we filed counterclaims seeking declarations of non-infringement and invalidity of certain U. S.  patents held by PDL.
Alexion believes it has good and valid defenses to PDL's claims and intends to vigorously defend the case and pursue its counterclaims.
On February 4, 2008, SB2, Inc.  filed a civil action against Alexion in the United States District Court for the Northern District of California.
SB2, Inc.  claims willfull infringement by Alexion of SB2, Inc.  patents due to sales of Soliris.
SB2, Inc.  seeks unspecified monetary damages, equitable relief and attorneys fees.
Alexion believes it has good and valid defenses to SB2's claims and intends to vigorously defend the case and pursue its counterclaims.
The results of such civil actions cannot be predicted with certainty due to their early stages.
However, depending on the outcome of these legal matters, the operating results of the Company could be materially impacted through adjustments to cost of sales (see Notes 2, 6 and 15 for additional information related to royalties).
Product Supply The Large-Scale Product Supply Agreement dated December 18, 2002, or the Lonza Agreement, between Lonza Sales AG, or Lonza, and us, relating to the manufacture of Soliris, was amended in June 2007.
We amended our supply agreement to provide for additional purchase commitments of Soliris of $30,000 to $35,000 through 2013.
Such commitments may only be cancelled in limited circumstances.
The fair values of the plan assets at December 31, 2015 by asset category (see Note P) are as follows:
## Table 1 ##
(a) - (f) Reference is made to footnotes (a) through (f) in the above table of other postretirement benefit plan assets at December 31, 2016 by asset category.
Mortality Table Revision The Companies adopted revised mortality tables effective December 31, 2014 in the measurement of its pension and other postretirement benefit plan obligations, accounting costs, and required contribution amounts as discussed in Note E.  As a result of the adoption, Con Edison recognized an increase of less than $10 million in its other postretirement benefits obligation as of December 31, 2014.
The Companies, under their current New York rate plans, defer as a regulatory asset or liability, as the case may be, the differences between the actual level of expenses for pension and other postretirement benefits and amounts for those expenses reflected in rates.
Note G – Environmental Matters Superfund Sites Hazardous substances, such as asbestos, polychlorinated biphenyls (PCBs) and coal tar, have been used or generated in the course of operations of the Utilities and their predecessors and are present at sites and in facilities and equipment they currently or previously owned, including sites at which gas was manufactured or stored.
The Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 and similar state statutes (Superfund) impose joint and several liability, regardless of fault, upon generators of hazardous substances for investigation and remediation costs (which include costs of demolition, removal, disposal, storage, replacement, containment and monitoring) and natural resource damages.
Liability under these laws can be material and may be imposed for contamination from past acts, even though such past acts may have been lawful at the time they occurred.
The sites at which the Utilities have been asserted to have liability under these laws, including their manufactured gas plant sites and any neighboring areas to which contamination may have migrated, are referred to herein as “Superfund Sites.
” For Superfund Sites where there are other potentially responsible parties and the Utilities are not managing the site investigation and remediation, the accrued liability represents an estimate of the amount the Utilities will need to pay to investigate and, where determinable, discharge their related obligations.
For Superfund Sites (including the manufactured gas plant sites) for which one of the Utilities is managing the investigation and remediation, the accrued liability represents an estimate of the company’s share of the undiscounted cost to investigate the sites and, for sites that have been investigated in whole or in part, the cost to remediate the sites, if remediation is necessary and if a reasonable estimate of such cost can be made.
Remediation costs are estimated in light of the information available, applicable remediation standards and experience with similar sites.
The accrued liabilities and regulatory assets related to Superfund Sites at December 31, 2016 and 2015 were as follows:
resolution of its remaining liability for uncertain tax positions, which will depend on the progress of tax examinations with the various tax authorities.
See Note L to the financial statements in Item 8.
The Companies’ commitments to make payments in addition to these contractual commitments include their other liabilities reflected in their balance sheets, any funding obligations for their pension and other postretirement benefit plans, financial hedging activities, their collective bargaining agreements and Con Edison’s guarantees of certain obligations of the Clean Energy Businesses and CET - Electric.
See Notes E, F, O and “Guarantees” in Note H to the financial statements in Item 8.
Capital Resources Con Edison is a holding company that operates only through its subsidiaries and has no material assets other than its interests in its subsidiaries.
Con Edison finances its capital requirements primarily through internally-generated funds and the sale of its securities.
Con Edison’s ability to make payments on external borrowings and dividends on its common shares depends on receipt of dividends from its subsidiaries or proceeds from the sale of its securities or its interests in its subsidiaries.
For information about restrictions on the payment of dividends by the Utilities and significant debt covenants, see Note C to the financial statements in Item 8.
For information on the Companies’ commercial paper program and revolving credit agreements with banks, see Note D to the financial statements in Item 8.
The Companies require access to the capital markets to fund capital requirements that are substantially in excess of available internally-generated funds.
See “Capital Requirements,” above.
Each of the Companies believes that it will continue to be able to access capital, although capital market conditions may affect the timing and cost of the Companies’ financing activities.
The Companies monitor the availability and costs of various forms of capital, and will seek to issue Con Edison common stock and other securities when it is necessary or advantageous to do so.
For information about the Companies’ long-term debt and short-term borrowing, see Notes C and D to the financial statements in Item 8.
Con Edison plans to meet its 2017 capital requirements through internally-generated funds and the issuance of securities.
The company’s plans include the issuance of between $1,000 million and $1,800 million of long-term debt, most of which would be at the Utilities, and the issuance of additional debt secured by its renewable electric production projects.
The company’s plans also include the issuance of up to $350 million of common equity in addition to equity under its dividend reinvestment, employee stock purchase and long term incentive plans.
The Utilities finance their operations, capital requirements and payment of dividends to Con Edison from internallygenerated funds, contributions of equity capital from Con Edison, if any, and external borrowings.
See "Liquidity and Capital Resources" in Item 7.
In 2016, the NYSPSC authorized CECONY, through 2019, to issue up to $5,200 million of debt securities ($1,300 million of which the company had issued as of December 31, 2016).
In 2013, the NYSPSC authorized O&R, through 2017, to issue up to $305 million of debt securities ($295 of which the company had issued as of December 31, 2016).
The NYSPSC also authorized CECONY and O&R for such periods to issue up to $2,500 million and $125 million, respectively, of debt securities to refund existing debt securities.
At December 31, 2016, the Utilities had not refunded any securities pursuant to this authorization.
The Clean Energy Businesses have financed their operations and capital requirements primarily with capital contributions and borrowings from Con Edison, internally-generated funds and external borrowings.
See "Liquidity and Capital Resources" in Item 7.

CECONY
## Table 3 ##
Electric CECONY’s results of electric operations for the year ended December 31, 2015 compared with the year ended December 31, 2014 is as follows
## Table 4 ##
CECONY’s electric sales and deliveries in 2015 compared with 2014 were
## Table 5 ##
(a) Revenues from electric sales are subject to a revenue decoupling mechanism, as a result of which, delivery revenues generally are not affected by changes in delivery volumes from levels assumed when rates were approved.
(b) “Residential/Religious” generally includes single-family dwellings, individual apartments in multi-family dwellings, religious organizations and certain other not-for-profit organizations.
(c) Other electric operating revenues generally reflect changes in regulatory assets and liabilities in accordance with the revenue decoupling mechanism and other provisions of the company’s rate plans.
See Note B to the financial statements in Item 8.
(d) After adjusting for variations, principally weather and billing days, electric delivery volumes in CECONY’s service area decreased 0.9 percent in 2015 compared with 2014.
Operating revenues decreased $265 million in 2015 compared with 2014 due primarily to lower purchased power expenses ($352 million) and lower fuel expenses ($62 million), offset in part by higher revenues from the electric rate plan ($156 million) .
Purchased power expenses decreased $352 million in 2015 compared with 2014 due to a decrease in unit costs ($381 million), offset by an increase in purchased volumes ($29 million
Clean Energy Businesses The Clean Energy Businesses’ results of operations for the year ended December 31, 2015 compared with the year ended December 31, 2014 is as follows:
