ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of the notes we are offering and certain other matters about us and our financial condition. The second part, the accompanying base prospectus, provides general information about the debt securities that we may offer from time to time, some of which may not apply to the notes we are offering hereby. Generally, when we refer to the prospectus, we are referring to both this prospectus supplement and the accompanying base prospectus. If the description of the notes varies between this prospectus supplement and the accompanying base prospectus, you should rely on the information in this prospectus supplement. References in this prospectus to “Edison International,” “we,” “us,” and “our” mean Edison International on a stand-alone basis, not consolidated with its subsidiaries.

FORWARD-LOOKING STATEMENTS

This prospectus and the documents they incorporate by reference contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements reflect our current expectations and projections about future events based on our knowledge of present facts and circumstances and assumptions about future events and include any statement that does not directly relate to a historical or current fact. In this prospectus and elsewhere, the words “expects,” “believes,” “anticipates,” “estimates,” “projects,” “intends,” “plans,” “probable,” “may,” “will,” “could,” “would,” “should,” and variations of such words and similar expressions, or discussions of strategy or of plans, are intended to identify forward-looking statements. Such statements necessarily involve risks and uncertainties that could cause actual results to differ materially from those anticipated. Some of the risks, uncertainties and other important factors that could cause results to differ, or that otherwise could impact us and our subsidiaries, include, but are not limited to:

decisions and other actions by the California Public Utilities Commission (“CPUC”), the Federal Energy Regulatory Commission, the Nuclear Regulatory Commission and other regulatory authorities, including determinations of authorized rate of return or return on equity, approval of proposed spending on grid modernization, outcome of San Onofre CPUC proceedings, and delays in regulatory actions;

•

our ability to borrow funds and access capital markets on reasonable terms;

•

risks associated with cost allocation, including the potential movement of costs to certain customers, caused by the ability of cities, counties and certain other public agencies to generate and/or purchase electricity for their local residents and businesses, along with other possible customer bypass or departure due to increased adoption of distributed energy resources or technological advancements in the generation, storage, transmission, distribution and use of electricity, and supported by public policy, government regulations and incentives;

•

risks inherent in the construction of SCE’s transmission and distribution infrastructure investment program, including those related to project site identification, public opposition, environmental mitigation, construction, permitting, power curtailment costs (payments due under power contracts in the event there is insufficient transmission to enable acceptance of power delivery) and governmental approvals;

•

risks associated with the operation of transmission and distribution assets and power generating facilities including: public safety issues, failure, availability, efficiency and output of equipment and availability and cost of spare parts;

S-1

•

risks associated with the decommissioning of San Onofre, including those related to public opposition, permitting, governmental approvals, and cost overruns;

•

physical security of our critical assets and personnel and the cyber security of our critical information technology systems for grid control, and business and customer data;

•

ability to develop our competitive businesses, manage new business risks, and recover and earn a return on our investment in newly developed or acquired businesses;

•

cost and availability of electricity, including the ability to procure sufficient resources to meet expected customer needs in the event of power plant outages or significant counterparty defaults under power-purchase agreements;

•

environmental laws and regulations, both at the state and federal levels, or changes in the application of those laws, that could require additional expenditures or otherwise affect the cost and manner of doing business;

•

changes in tax laws and regulations, at both the state and federal levels, or changes in the application of those laws; that could affect recorded deferred tax assets and liabilities and effective tax rates;

•

changes in the fair value of investments and other assets;

•

changes in interest rates and rates of inflation, including escalation rates, which may be adjusted by public utility regulators;

•

governmental, statutory, regulatory or administrative changes or initiatives affecting the electricity industry, including the market structure rules applicable to each market adopted by the North American Electric Reliability Corporation, Regional Transmission Organizations, and similar regulatory bodies in adjoining regions;

•

availability and creditworthiness of counterparties and the resulting effects on liquidity in the power and fuel markets and/or the ability of counterparties to pay amounts owed in excess of collateral provided in support of their obligations;

•

cost and availability of labor, equipment and materials;

•

our ability to obtain sufficient insurance, including insurance relating to SCE’s nuclear facilities and wildfire-related liability, and to recover the costs of such insurance or in the absence of insurance the ability to recover uninsured losses;

•

potential for penalties or disallowances for non-compliance with applicable laws and regulations;

•

cost of fuel for generating facilities and related transportation, which could be impaired by, among other things, disruption of natural gas storage facilities, to the extent not recovered through regulated rate cost escalation provisions or balancing accounts;

•

disruption of natural gas supply due to unavailability of storage facilities, which could lead to electricity service interruptions; and

•

weather conditions and natural disasters.

Additional information about risks and uncertainties that could cause results to differ from those currently expected or that otherwise could impact us, including more detail about the factors described above, is included in our Annual Report on Form 10-K for the year ended December 31, 2016 and our Current Reports on Form 8-K filed subsequent to that date. Forward-looking statements speak only as of the date they are made and we are not obligated to publicly update or revise forward-looking statements.

RISK FACTORS

Your decision whether or not to purchase any of the notes will involve some degree of risk. You should be aware of and carefully consider the following risk factors and the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2016 (which is incorporated by reference in this prospectus supplement and the related base prospectus). New risks may emerge at any time, and we cannot predict such risks or estimate the extent to which they may affect our financial performance. You should also read and consider all of the other information provided or incorporated by reference in this prospectus supplement and the related base prospectus before deciding whether or not to purchase any of the notes. See “Forward-Looking Statements” in this prospectus supplement and “Where You Can Find More Information” in the base prospectus.

You may be unable to sell your notes if a trading market for the notes does not develop.

The notes will be a new series of securities for which there is currently no established trading market, and none may develop. We do not intend to apply for listing of the notes on any securities exchange or for quotation on any automated dealer quotation system. The liquidity of any market for the notes will depend on the number of holders of the notes, the interest of securities dealers in making a market in the notes, and other factors. Accordingly, we cannot assure you as to the development or liquidity of any market for the notes. If an active trading market does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price depending upon prevailing interest rates, the market for similar securities, general economic conditions, our performance and business prospects, and certain other factors.

The notes are our obligations and not obligations of our subsidiaries and will be effectively subordinated to the claims of the subsidiaries’ creditors.

The notes are our obligations exclusively and not obligations of our subsidiaries. Because we are a holding company, our obligations under the notes will be structurally subordinated to all existing and future liabilities and preferred equity of our subsidiaries. Therefore, our creditors, including holders of the notes, will not have a direct right to participate in the assets of any subsidiary upon the liquidation or reorganization of the subsidiary. Instead, our creditors will participate in those assets only to the extent that we receive a distribution from the subsidiary on account of any claim or interest that we have against or in the subsidiary. At December 31, 2016, our subsidiaries had total consolidated liabilities of approximately $36 billion and preferred equity outstanding with a total liquidation value of approximately $2.2 billion. SCE expects to issue $700 million of first and refunding mortgage bonds in March 2017.

We may be unable to meet our ongoing and future financial obligations if our subsidiaries are unable to pay dividends to us.

Our ability to meet our financial obligations is primarily dependent on the earnings and cash flows of our subsidiaries and their ability to pay dividends, make other distributions or repay funds owed from time to time to us. Prior to funding Edison International, our subsidiaries have financial and regulatory obligations that must be satisfied, including, among others, debt service and preferred stock dividends. The CPUC also regulates SCE’s capital structure and limits the dividends it may pay to us. In addition, the indenture under which the notes will be issued does not limit our ability, or the ability of our subsidiaries, to pledge shares of stock as security for other indebtedness.

S-4

USE OF PROCEEDS

We intend to use the net proceeds from the offering of the notes to repay commercial paper borrowings and/or for general corporate purposes. The current weighted average interest rate of our commercial paper borrowings is 1.02%.

S-5

CERTAIN TERMS OF THE NOTES

The notes will be a series of our debt securities issued under an indenture dated as of September 10, 2010 between Edison International, as issuer, and The Bank of New York Mellon Trust Company, N.A., as trustee.

The summary of selected provisions of the notes and the indenture referred to below supplements, and to the extent inconsistent supersedes and replaces, the description of the general terms and provisions of the debt securities and the indenture contained in the accompanying base prospectus. This summary is not complete and is qualified by reference to provisions of the notes and the indenture. Forms of the notes and the indenture have been or will be filed with the Securities and Exchange Commission and you may obtain copies as described under “Where You Can Find More Information” in the accompanying base prospectus.

Interest Rate and Maturity

The notes will bear interest at the rate of 2.125% per year. Interest on the notes will be payable semi-annually in arrears on April 15 and October 15 of each year, beginning on October 15, 2017, to the holders of record at the close of business on the immediately preceding April 1 and October 1, respectively. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months; provided that the amount of interest payable for any period shorter or longer than a full interest period will be computed on the basis of a 360-day year consisting of twelve 30-day months and the actual number of days elapsed in the period using 30-day months.

The notes will mature on April 15, 2020. The notes are subject to earlier redemption at our option as described under “—Optional Redemption.”

If any interest payment date, redemption date or the maturity date of the notes is not a business day in any place of payment, then payment of the principal, premium, if any, and interest may be made on the next business day in that place of payment. In that case, no interest will accrue on the amount payable for the period from and after the applicable interest payment date, redemption date or maturity date, as the case may be. The regular record date for all payments of interest on the notes will be the first day of the month in which payment is to be made, whether or not such day is a business day.

We will pay interest on, principal of, and any premium on, the notes at stated maturity, upon redemption or otherwise, as described under “—Book-Entry, Delivery and Form.” The notes initially will be issued in book-entry form and represented by global securities deposited with, or on behalf of, The Depository Trust Company, as Depositary, and registered in the name of Cede & Co., its nominee. This means that you will not be entitled to receive a certificate for the notes that you purchase except in limited circumstances. If any of the notes are issued in certificated form they will be issued only in fully registered form without coupons, in denominations of $1,000 and integral multiples of $1,000.

Ranking

The notes will be our unsecured senior debt obligations and will rank on a parity in right of payment with all of our other unsecured and unsubordinated indebtedness. The notes are our obligations exclusively, and are not the obligations of any of our subsidiaries. Because we conduct our operations primarily through our subsidiaries and substantially all of our consolidated assets are held by our subsidiaries, the notes will be effectively subordinated to all existing and future liabilities (including indebtedness) and preferred equity of our subsidiaries. At December 31, 2016, our subsidiaries had total consolidated liabilities of approximately $36 billion, and preferred equity outstanding with a total liquidation value of approximately $2.2 billion. SCE expects to issue $700 million of first and refunding mortgage bonds in March 2017. See “Description of the Debt Securities—Ranking—Holding Company Structure” in the accompanying base prospectus.

S-6

Optional Redemption

We will be entitled to redeem the notes at our option as described below. You will not be permitted to require us to redeem or repurchase the notes at your option.

All or a portion of the notes may be redeemed at our option at any time or from time to time. The redemption price for the notes to be redeemed on any redemption date will be equal to the greater of the following amounts:

•

100% of principal amount; or

•

the sum of the present values of the remaining scheduled payments of principal and interest on the notes being redeemed on that redemption date (not including any portion of any payments of interest accrued to the redemption date) discounted to the redemption date on a semi-annual basis at the Adjusted Treasury Rate (as defined below) plus 10 basis points, as determined by the Independent Investment Banker (as defined below),

plus, in each case, accrued and unpaid interest on the notes to be redeemed to but excluding the redemption date. The redemption price will be calculated by us on the basis of a 360-day year consisting of twelve 30-day months.

Notwithstanding the foregoing, installments of interest on notes that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date according to the notes and the indenture.

“Adjusted Treasury Rate” means, for any date fixed for redemption, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for the date fixed for redemption.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term to stated maturity of the bonds to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the bonds to be redeemed.

“Comparable Treasury Price” means, for any date fixed for redemption, the average of the Reference Treasury Dealer Quotations for the date fixed for redemption, or if only one Reference Treasury Dealer quotation is received, such quotation.

“Independent Investment Banker” means Barclays Capital Inc. or its successor or, if such firm or its successor, as applicable, is unwilling or unable to select the Comparable Treasury Issue, one of the remaining Reference Treasury Dealers appointed by us.

“Reference Treasury Dealer” means (1) Barclays Capital Inc., Wells Fargo Securities, LLC, and any other primary U.S. Government securities dealer in the United States of America (a “Primary Treasury Dealer”) designated by, and not affiliated with, any of the foregoing or their successors, provided, however, that if any of the foregoing, or any of their designees, ceases to be a Primary Treasury Dealer, we will appoint another Primary Treasury Dealer as a substitute, and (2) any other Primary Treasury Dealer selected by us.

“Reference Treasury Dealer Quotations” means, for each Reference Treasury Dealer and any date fixed for redemption, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing

S-7

to the Independent Investment Banker by the Reference Treasury Dealer at 5:00 p.m. New York City time on the third business day preceding the date fixed for redemption.

We will provide notice of any redemption at least 30 days but not more than 60 days before the redemption date to the registered holders of the notes to be redeemed. We may make any redemption conditional upon the receipt by the paying agent, on or prior to the date fixed for redemption, of money sufficient to pay the redemption price. If the paying agent has not received the money by the date fixed for redemption, we will not be required to redeem the debt securities. See “Description of the Debt Securities—Redemption” in the accompanying base prospectus.

Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

No Sinking Fund

There will be no provisions for any sinking funds for the notes.

Other

We may, from time to time, without notice to or the consent of the holders of the notes, increase the principal amount of the notes under the indenture and issue such increased principal amount (or any portion thereof), in which case any additional notes so issued shall have the same form and terms (other than the date of issuance, public offering price, and, under certain circumstances, the date from which interest thereon shall begin to accrue and the first interest payment date), and shall carry the same right to receive accrued and unpaid interest as the notes previously issued, and such additional notes shall form a single series with the notes offered by this prospectus supplement, provided that such additional notes shall be fungible with the notes offered by this prospectus supplement for United States federal income tax purposes.

Book-Entry, Delivery, and Form

The notes will be represented by one or more permanent global notes in definitive, fully registered form without interest coupons. Upon issuance, the notes will be deposited with The Bank of New York Mellon Trust Company, N.A., as trustee, as custodian for The Depository Trust Company in New York, New York (which we refer to as “DTC”), and registered in the name of DTC or its nominee.

Ownership of beneficial interests in a global note will be limited to persons who have accounts with DTC, which we refer to as “participants,” or persons who hold interests through participants. Ownership of beneficial interests in a global note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants).

So long as DTC, or its nominee, is the registered owner or holder of any of the notes, DTC or that nominee, as the case may be, will be considered the sole owner or holder of such notes represented by the global note for all purposes under the note indenture and the notes. No beneficial owner of an interest in a global note will be able to transfer such interest except in accordance with DTC’s applicable procedures, in addition to those provided for under the note indenture.

Payments of the principal of, and interest on, a global note will be made to DTC or its nominee, as the case may be, as the registered owner thereof. None of the trustee, any paying agent, or we will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

S-8

We expect that DTC or its nominee, upon receipt of any payment of principal or interest in respect of a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global note as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in such global note held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

We expect that transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and procedures and will be settled in same-day funds.

We expect that DTC will take any action permitted to be taken by a holder of notes only at the direction of one or more participants to whose account the DTC interests in a global note is credited and only in respect of such portion of the aggregate principal amount of notes as to which such participant or participants has or have given such direction.

A global note is exchangeable for definitive notes in registered certificate form if:

•

DTC (i) notifies us that it is unwilling or unable to continue as depositary for the global notes, and we fail to appoint a successor depositary, or (ii) has ceased to be a clearing agency registered under the Securities Exchange Act of 1934, as amended; or

•

at our option, we notify the trustee in writing that we have elected to cause the issuance of the certificated securities.

In all cases, certificated securities delivered in exchange for any global note or beneficial interests in global notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures). Certificated securities may be presented for registration, transfer and exchange at The Bank of New York Mellon Trust Company, N.A., Chicago, Illinois, or the office or agency designated for such purpose.

DTC has advised us that: DTC is a limited purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the Uniform Commercial Code and a “Clearing Agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies and certain other organizations that clear through or maintain a custodial relationship with a participant, either directly or indirectly, whom we refer to as indirect participants.

Although DTC is expected to follow the foregoing procedures in order to facilitate transfers of interests in a global note among participants of DTC, they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. None of the trustee, the paying agent, nor we will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Same Day Settlement and Payment

We will make payments in respect of the notes represented by the global notes (including principal, interest and premium, if any) by wire transfer of immediately available funds to the accounts specified by the global noteholder. We will make all payments of principal, interest and premium with respect to certificated securities by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no account

S-9

is specified, by mailing a check to that holder’s registered address. The exchange notes represented by the global notes are expected to trade in DTC’s Same Day Funds Settlement System, and any permitted secondary market trading activity in the notes will, therefore, be required by DTC to be settled in immediately available funds. We expect that secondary trading in any certificated securities will also be settled in immediately available funds.

S-10

UNDERWRITING

Barclays Capital Inc. and Wells Fargo Securities, LLC (together, the “Representatives”), as representatives of the underwriters named below, have entered into an underwriting agreement, dated the date of this prospectus supplement, with Edison International relating to the offer and sale of the notes. In the underwriting agreement, Edison International has agreed to sell to each underwriter, and each underwriter has severally agreed to purchase from Edison International, the principal amount of notes set forth opposite its name below:


Underwriter	Principal Amount of Notes to be Purchased
Barclays Capital Inc.	$	180,000,000
Wells Fargo Securities, LLC.		180,000,000
BNP Paribas Securities Corp		20,000,000
PNC Capital Markets LLC		20,000,000

Total	$	400,000,000

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the notes if they purchase any of the notes.

The underwriters propose to offer the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and may offer the notes to dealers at the public offering price less a concession not to exceed 0.200% of the principal amount of the notes. The underwriters may allow, and dealers may reallow a concession not to exceed 0.125% of the principal amount of the notes on sales to other dealers. After the initial offering of the notes to the public, the underwriters may change the public offering price and concessions.

In connection with this offering, we will pay an underwriting discount to the underwriters of 0.350% of the principal amount of the notes.

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include over-allotment, syndicate covering transactions, and stabilizing transactions. Over-allotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased by the underwriter in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the underwriters, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member.

Any of these activities may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

We estimate that our total expenses for this offering, excluding the underwriting discount, will be $500,000.

Certain of the underwriters and their affiliates have performed investment banking, commercial banking and advisory services for us and our affiliates from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time, engage in transactions with and perform services for us and our affiliates in the ordinary course of their business.

S-11

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve our securities and instruments or those of our affiliates. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

We expect delivery of the notes will be made against payment therefor on or about March 29, 2017, which is the fifth business day after the date of this prospectus. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of this prospectus or the next succeeding business day will be required, by virtue of the fact that the notes initially will not settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisor.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

Selling Restrictions

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

DESCRIPTION OF THE DEBT SECURITIES

The following is a general description of the terms and provisions of the debt securities we may offer and sell by this prospectus in one or more distinct offerings. This summary is not meant to be a complete description of each series of debt securities. This prospectus and any accompanying prospectus supplement will contain the particular terms and conditions for each series of debt securities. For more information about the debt securities, please refer to the indenture dated as of September 10, 2010 between Edison International and The Bank of New York Mellon Trust Company, N.A., as trustee, for the issuance of debt securities, which we refer to as the “indenture” in this prospectus.

We have filed a copy of the indenture as an exhibit to the registration statement that includes this prospectus. We refer to the trustee for the indenture as the “indenture trustee.” The indenture is governed by the Trust Indenture Act of 1939 and may be supplemented or amended from time to time.

The indenture gives us broad authority to set the particular terms of each series of debt securities, including the right to modify certain of the terms contained in the indenture. The particular terms of a series of debt securities and the extent, if any, to which the particular terms of the issue modify the terms of the indenture will be described in the prospectus supplement relating to the debt securities.

The indenture contains the full legal text of the matters described in this section. Because this section is a summary, it does not describe every aspect of the debt securities or the indenture. This summary is subject to and qualified by all the provisions of the indenture, including definitions of terms used in the indenture. Therefore, you should read carefully the detailed provisions of the indenture, which we have incorporated by reference as an exhibit to the registration statement that includes this prospectus. This summary also is subject to and qualified by the description of the particular terms of the debt securities in the applicable prospectus supplement.

General

We may issue an unlimited amount of debt securities under the indenture in one or more series. We need not issue all debt securities of one series at the same time and, unless otherwise provided, we may reopen a series, without the consent of the holders of the debt securities of that series, for issuances of additional debt securities of that series.

Prior to the issuance of each series of debt securities, the terms of the particular debt securities will be specified in a supplemental indenture (including any pricing supplement) or in one or more officer’s certificates of Edison International pursuant to a supplemental indenture or a board resolution. We refer you to the applicable prospectus supplement for a description of the following terms, among others, of the series of debt securities:

•

the title of the debt securities;

•

any limit upon the aggregate principal amount of the debt securities of that series;

•

the date or dates on which principal will be payable or how to determine the dates;

•

the rate or rates or method of determination of interest; the date from which interest will accrue; the dates on which interest will be payable, which we refer to as the “interest payment dates;” and any record dates for the interest payable on the interest payment dates;

•

any obligation or option of Edison International to redeem, purchase or repay debt securities, or any option of the registered holder to require Edison International to redeem or repurchase debt securities, and the terms and conditions upon which the debt securities will be redeemed, purchased or repaid;

•

the denominations in which the debt securities will be issuable (if other than denominations of $1,000 and any integral multiple of $1,000 in excess thereof);

•

any provision relating to deferral of interest payments;

•

whether the debt securities are subject to discharge or defeasance at our option;

•

whether the debt securities are to be issued in whole or in part in the form of one or more global debt securities and, if so, the identity of the depositary for the global debt securities; and

•

any other terms of the debt securities.

Ranking

The debt securities will be unsecured senior debt obligations of Edison International. The indebtedness represented by the debt securities will rank equally with all other unsecured and unsubordinated debt of Edison International.

Holding Company Structure

Edison International conducts its operations through its subsidiaries and substantially all of its consolidated assets are held by its subsidiaries. Accordingly, Edison International’s cash flow and its ability to meet its obligations under its debt securities are largely dependent upon the earnings of its subsidiaries and the distribution or other payment of these earnings to Edison International. The subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on the Edison International debt securities or to make any funds available for payment of amounts due on these debt securities.

Because Edison International is a holding company, its obligations under the debt securities will be structurally subordinated to all existing and future liabilities and preferred equity of its subsidiaries. Therefore, the rights of Edison International’s creditors, including the rights of the holders of the debt securities issued by Edison International, to participate in the assets of any subsidiary upon the liquidation or reorganization of the subsidiary will depend on the rights of Edison International against the subsidiary. In that regard, Edison International’s equity interest in the subsidiary would be subject to the prior claims of the subsidiary’s creditors and preferred stockholders. To the extent that Edison International may itself be a creditor with recognized claims against any of its subsidiaries, Edison International’s claims would be subordinated to any security interest in, or mortgages or other liens on, the assets of the subsidiary or any other indebtedness or other liabilities of the subsidiary that are senior to the claims held by Edison International.

Payment of Debt Securities—Interest

Unless indicated otherwise in an applicable prospectus supplement, we will pay interest on the debt security on each interest payment date to the person in whose name the debt security is registered as of the close of business on the regular record date relating to the interest payment date.

Unless otherwise specified in connection with a particular offering of debt securities:

•

if an interest payment date falls on a day that is not a Business Day, the payment due on such interest payment date will be postponed to the next succeeding Business Day and no further interest will accrue in respect of such postponement;

•

interest will be computed on the basis of a 360-day year consisting of twelve 30-day months; provided that the amount of interest payable for any period shorter or longer than a full interest period will be computed on the basis of a 360-day year consisting of twelve 30-day months and the actual number of days elapsed in the period using 30-day months; and

•

in this section, “Business Day” means any day which is a day on which commercial banks settle payments and are open for general business in Los Angeles.

If a date for payment of interest or principal on the debt securities falls on a day that is not a business day in the place of payment, such payment will be made on the next succeeding business day in such place of payment as if made on the date the payment was due. No interest will accrue on any amounts payable for the period from and after the due date for payment of such principal or interest.

If we default in paying interest on a debt security, we will pay defaulted interest in either of the two following ways:

•

We will first propose to the indenture trustee a payment date for the defaulted interest. Next, the indenture trustee will choose a special record date for determining which registered holders are entitled to the payment. The special record date will be between 10 and 15 days before the payment date we propose. Finally, we will pay the defaulted interest on the payment date to the registered holder of the debt security as of the close of business on the special record date.

•

Alternatively, we can propose to the indenture trustee any other lawful manner of payment, provided that is not inconsistent with the requirements of any securities exchange on which the debt securities are listed for trading, if any. If the indenture trustee thinks the proposal is practicable, payment will be made as proposed.

Payment of Debt Securities—Principal

Unless indicated otherwise in an applicable prospectus supplement, we will pay principal of and any premium on the debt securities at stated maturity, upon redemption or otherwise, upon presentation of the debt securities at the office of the indenture trustee, as our initial paying agent. Any other paying agent initially designated for the debt securities of a particular series will be named in the applicable prospectus supplement.

In our discretion, we may change the place of payment on the debt securities, and may remove any paying agent, may appoint one or more additional paying agents, and may act as our own paying agent.

If the stated maturity of the debt securities falls on a day that is not a Business Day, the payment due at stated maturity will be postponed to the next succeeding Business Day, and no further interest will accrue in respect of such postponement.

Form; Transfers; Exchanges

Unless we indicate otherwise in an applicable prospectus supplement, the debt securities will be issued

•

only in fully registered form;

•

without interest coupons; and

•

in denominations of $1,000 and any integral multiple of $1,000 in excess thereof.

Global Debt Securities

We may issue debt securities of any series in whole or in part in the form of one or more global debt securities that will be deposited with, or on behalf of, The Depositary Trust Company (“DTC”) or a depositary identified in the prospectus supplement relating to that series. Unless and until it is exchanged in whole or in part for individual certificates evidencing debt securities in definitive form, a global security may not be transferred except as a whole by the depositary for that global security to a nominee of that depositary or by a nominee of that depositary to that depositary or another nominee of that depositary or by that depositary or that nominee to a successor of that depositary or a nominee of that successor. We will describe the specific terms of the depositary arrangement for a series of debt securities, and how that arrangement may affect the process for receiving payments on the debt securities, in the prospectus supplement relating to that series.

Exchange

You may have your debt securities divided into debt securities of smaller denominations (of at least $1,000) or combined into debt securities of larger denominations, as long as the total principal amount is not changed. This is called an “exchange.”

You may exchange or transfer debt securities (other than debt securities represented by a global security) at the office of the indenture trustee. The indenture trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities (other than debt securities represented by a global security). We may appoint another agent or act as our own agent for this purpose. The entity performing the role of maintaining the list of registered holders is called the “security registrar.” It will also perform transfers, if applicable.

In our discretion, we may change the place for registration of transfer of the debt securities (other than debt securities represented by a global security) and may remove and/or appoint one or more additional security registrars.

Except as otherwise provided in a prospectus supplement, there will be no service charge for any transfer or exchange of the debt securities, but you may be required to pay a sum sufficient to cover any tax or other governmental charge payable in connection with the transfer or exchange. We may block the transfer or exchange of (a) debt securities during a period of 15 days prior to mailing any notice of redemption or (b) any debt security selected for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part.

Redemption

We will set forth any terms for the redemption of debt securities in a prospectus supplement. Unless we indicate otherwise in a prospectus supplement, and except with respect to debt securities redeemable at the option of the registered holder, debt securities will be redeemable upon notice mailed between 30 and 60 days prior to the redemption date. If less than all of the debt securities of any series or any tranche of a series are to be redeemed, the indenture trustee will select the debt securities to be redeemed. In the absence of any provision for selection, the indenture trustee will choose a method of random selection it deems fair and appropriate.

Debt securities will cease to bear interest on the redemption date. We will pay the redemption price and any accrued interest to but excluding the redemption date once you surrender the debt security for redemption. If only part of a debt security is redeemed, the indenture trustee will deliver to you a new debt security of the same series for the remaining portion without charge.

We may make any redemption conditional upon the receipt by the paying agent, on or prior to the date fixed for redemption, of money sufficient to pay the redemption price. If the paying agent has not received the money by the date fixed for redemption, the redemption will not occur.

Events of Default

An “event of default” occurs with respect to debt securities of any series if:

(a)

we do not pay any interest on any debt securities of the applicable series within 30 days of the due date (following any deferral allowed under the terms of the debt securities and elected by us);

(b)

we do not pay principal or premium on any debt securities of the applicable series on the due date;

(c)

we do not pay any sinking fund installment on debt securities of the series within 60 days of the due date;

(d)

we remain in breach of a covenant (excluding covenants not applicable to the affected series) of the indenture for 90 days after we receive a written notice of default stating we are in breach and requiring remedy of the breach; the notice must be sent by either the indenture trustee or registered holders of at least 33% of the principal amount of debt securities of the affected series;

(e)

we file for bankruptcy or other specified events in bankruptcy, insolvency, or reorganization occur; or

(f)

any other event of default specified in the applicable prospectus supplement occurs.

No event of default with respect to a series of debt securities necessarily constitutes an event of default with respect to the debt securities of any other series issued under the indenture.

Remedies

Acceleration

If an event of default occurs and is continuing with respect to any series of debt securities, then either the indenture trustee or the registered holders of not less than 33% in principal amount of the outstanding debt securities of that series may declare the principal amount of all of the debt securities of that series to be due and payable immediately. If an event of default described in clauses (d) or (e) of “—Events of Default” above occurs and is continuing with respect to all series of debt securities, then either the indenture trustee or the registered holders of not less than 33% in principal amount of all outstanding debt securities may declare the principal amount of all outstanding debt securities to be due and payable immediately.

Rescission of Acceleration

After the declaration of acceleration has been made and before the indenture trustee has obtained a judgment or decree for payment of the money due on any series or all series of debt securities, as the case may be, the registered holders of not less than a majority in aggregate principal amount of the outstanding debt securities of that series or all series may rescind and annul the declaration and its consequences, if

•

we pay or deposit with the indenture trustee a sum sufficient to pay

•

all overdue interest;

•

the principal of and any premium which have become due other than by the declaration of acceleration and overdue interest on these amounts;

•

interest on overdue interest to the extent lawful;

•

all amounts due to the indenture trustee under the indenture; and

•

all events of default with respect to the affected series, other than the nonpayment of the principal which has become due solely by the declaration of acceleration, have been cured or waived as provided in the indenture.

For more information as to waiver of defaults, see “Waiver of Default and of Compliance” below.

Control by Registered Holders; Limitations

Subject to the indenture, if an event of default with respect to the debt securities of any series occurs and is continuing, the registered holders of a majority in principal amount of the outstanding debt securities of that series will have the right to

•

direct the time, method and place of conducting any proceeding for any remedy available to the indenture trustee, or

•

exercise any trust or power conferred on the indenture trustee with respect to the debt securities of the series.

If an event of default is continuing with respect to all the series of debt securities, the registered holders of a majority in aggregate principal amount of the outstanding debt securities of all the series, considered as one class, will have the right to make such direction, and not the registered holders of the debt securities of any one of the series. These rights of registered holders to make direction are subject to the following limitations:

•

the registered holders’ directions will not conflict with any law or the indenture; and

•

the registered holders’ directions may be declined to be followed by the indenture trustee where the indenture trustee determines such directions would involve it in personal liability.

The indenture trustee may also take any other action it deems proper which is consistent with the registered holders’ direction.

In addition, the indenture provides that no registered holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture for the appointment of a receiver or for any other remedy under the indenture unless

•

that registered holder has previously given the indenture trustee written notice of a continuing event of default;

•

the registered holders of not less than 33% in aggregate principal amount of the outstanding debt securities of all the affected series, considered as one class, or, in the case of an event of default described in clauses (a), (b) or (c) of “Events of Default,” above, that series, have made written request to the indenture trustee to institute proceedings in respect of that event of default and have offered the indenture trustee indemnity satisfactory to it against costs and liabilities incurred in complying with the request; and

•

for 60 days after receipt of the notice request and offer of such indemnity, the indenture trustee has failed to institute a proceeding and no direction inconsistent with the request has been given to the indenture trustee during the 60-day period by the registered holders of a majority in aggregate principal amount of outstanding debt securities of all the series, considered as one class, or, in the case of an event of default described in clauses (a), (b) or (c) of “Events of Default,” above, that series.

Furthermore, no registered holder will be entitled to institute any action if and to the extent that the action would disturb or prejudice the rights of other registered holders, seek to obtain priority or preference over other registered holders or enforce any right under the indenture except as provided in the indenture and for the equal and ratable benefit of all registered holders.

However, each registered holder has an absolute and unconditional right to receive payment when due and to bring a suit to enforce that right.

Notice of Default

The indenture trustee is required to give the registered holders of the debt securities notice of any default under the indenture to the extent required by the Trust Indenture Act of 1939, unless the default has been cured or waived; except that in the case of an event of default of the character specified above in clause (d) under “Events of Default,” no notice shall be given to the registered holders until at least 30 days after the occurrence thereof.

The Trust Indenture Act of 1939 currently permits the indenture trustee to withhold notices of default (except for certain payment defaults) if the indenture trustee in good faith determines the withholding of the notice to be in the interests of the registered holders.

We will furnish the indenture trustee with a statement each calendar year as to our compliance with the conditions and covenants in the indenture.

Waiver of Default and of Compliance

The registered holders of a majority in aggregate principal amount of the outstanding debt securities of all affected series (voting as one class) may waive, on behalf of the registered holders of all debt securities of all such series, any past default under the indenture, except a default in the payment of principal, premium or interest, or with respect to compliance with certain provisions of the indenture that cannot be amended without the consent of the registered holder of each outstanding debt security.

Compliance with some of the covenants in the indenture or otherwise provided with respect to debt securities may be waived by the registered holders of a majority in aggregate principal amount of the affected debt securities, considered as one class.

Covenants

Consolidation, Merger and Conveyance of Assets as an Entirety

Subject to the provisions described in the next paragraph, Edison International will preserve its corporate existence.

Edison International has agreed not to consolidate with or merge into any other entity and not to convey, transfer or lease its properties and assets substantially as an entirety to any entity, unless:

•

the entity formed by the consolidation or into which Edison International is merged, or the entity which acquires or which leases the property and assets of Edison International substantially as an entirety, is an entity organized and existing under the laws of the United States of America or any State of the United States or the District of Columbia, and expressly assumes, by supplemental indenture, the due and punctual payment of the principal, premium and interest on all the outstanding debt securities and the performance of all of the covenants of Edison International under the indenture,

•

immediately after giving effect to the transactions, no event of default, and no event which after notice or lapse of time or both would become an event of default, will have occurred and be continuing, and

•

we have given the indenture trustee an officers’ certificate and legal opinion that all conditions in the indenture relating to the transactions have been complied with.

Notwithstanding the foregoing, we may merge or consolidate with or transfer all or substantially all of its assets to an affiliate that has no significant assets or liabilities and was formed for the purpose of changing our jurisdiction of organization or our form of organization; provided that the successor assumes all of our obligations under the indenture.

No Financial Covenants

The indenture contains no financial or other similar restrictive covenants. Any such covenants with respect to any particular series of debt securities will be set forth in the applicable prospectus supplement.

Modification of Indenture

Without Registered Holder Consent

Without the consent of any registered holders of debt securities, we and the applicable indenture trustee may enter into one or more supplemental indentures for any of the following purposes:

•

to evidence the succession of another entity to Edison International; or

•

to add one or more covenants of Edison International or other provisions for the benefit of the registered holders of all or any series or tranche of debt securities, or to surrender any right or power conferred upon Edison International; or

•

to add any additional events of default for all or any series of debt securities; or

•

to add to, change or eliminate any provision of the indenture that does not adversely affect the interests of the registered holders in any material respect; or

•

to provide security for the debt securities of any series; or

•

to add guarantors for the debt securities of any series; or

•

to establish the form or terms of debt securities of any series or tranche or any debt securities guarantees as permitted by the indenture; or

•

to provide for the issuance of bearer securities; or

•

to evidence and provide for the acceptance of appointment of a separate or successor indenture trustee; or

•

to provide for the procedures required to permit the utilization of a noncertificated system of registration for any series or tranche of debt securities; or

•

to cure any ambiguity, defect or inconsistency or to make any other changes, provided that any such action does not adversely affect the interests of the holders of the debt securities in any material respect; or

•

to comply with the rules or regulations of any securities exchange or automated quotation system on which any series or tranche of debt securities may be listed or traded; or

•

to qualify the indenture under the Trust Indenture Act of 1939 or to add to the indenture any provisions expressly required by the Trust Indenture Act of 1939; or

•

to conform the indenture or any debt securities to the relevant description in this prospectus, a prospectus supplement or other disclosure document, provided that such changes do not adversely affect the interests of the holders of the debt securities in any material respect.

If the Trust Indenture Act of 1939 is amended after the date of the indenture so as to require changes to the indenture or so as to permit changes to, or the elimination of, provisions which, at the date of the indenture or at any time thereafter, were required by the Trust Indenture Act of 1939 to be contained in the indenture, the indenture will be deemed to have been amended so as to conform to the amendment or to effect the changes or elimination, regardless of whether Edison International and the applicable indenture trustee enter into one or more supplemental indentures to effect or evidence the amendment as described above.

In our discretion, with notice to the indenture trustee, we may change any place or places where

•

we may pay principal, premium and interest,

•

debt securities may be surrendered for transfer or exchange, or

•

notices and demands to or upon Edison International may be served.

With Registered Holder Consent

We and the indenture trustee may, with some exceptions, amend or modify any indenture with the consent of the registered holders of at least a majority in aggregate principal amount of the debt securities of all series affected by the amendment or modification (voting as one class). However, no amendment or modification may, without the consent of the registered holder of each outstanding debt security affected thereby,

•

change the stated maturity of the principal or interest on any debt security (other than pursuant to the terms of the debt security), or reduce the principal amount, interest or premium payable or change the currency in which any debt security is payable, or impair the right provided for in the indenture to bring suit to enforce any payment;

•

reduce the percentages of registered holders whose consent is required for any supplemental indenture or waiver or reduce the requirements for quorum and voting under the indenture; or

•

modify certain of the provisions in the indenture relating to supplemental indentures and waivers of certain covenants and past defaults.

A supplemental indenture which changes or eliminates any provision of the indenture expressly included solely for the benefit of registered holders of debt securities of one or more particular series or tranches will be deemed not to affect the rights under the indenture of the registered holders of debt securities of any other series or tranche.

Miscellaneous

The indenture provides that some debt securities, including those for which payment or redemption money has been deposited or set aside in trust, will not be deemed to be “outstanding” in determining whether the registered holders of the requisite principal amount of the outstanding debt securities have given or taken any demand, direction, consent or other action under the indenture as of any date, or are present at a meeting of registered holders for quorum purposes.

We will be entitled to set any day as a record date for the purpose of determining the registered holders of outstanding debt securities of any series entitled to give or take any demand, direction, consent or other action under the indenture, in the manner and subject to the limitations provided in the indenture. In some circumstances, the indenture trustee also will be entitled to set a record date for action by registered holders. If a record date is set for any action to be taken by registered holders of particular debt securities, the action may be taken only by persons who are registered holders of the respective debt securities on the record date.

Any money we provide to a paying agent for the payment of principal, premium or interest that remains unclaimed at the end of two years after the payment became due and payable will be repaid to us. Thereafter, the holder of debt securities entitled to such payment must look only to us for payment.

Defeasance and Covenant Defeasance

The indenture provides, unless the terms of the particular series of debt securities provide otherwise, that we may, upon satisfying several conditions, cause ourselves to be:

•

discharged from our obligations, with some exceptions, with respect to any series of debt securities, which we refer to as “defeasance”; and

•

released from our obligations under specified covenants with respect to any series of debt securities, which we refer to as “covenant defeasance.”

One condition we must satisfy is the irrevocable deposit with the indenture trustee, in trust, of money and/or government obligations which, through the scheduled payment of principal and interest on those obligations, would provide sufficient moneys to pay the principal of and any premium and interest on those debt securities on the maturity dates of the payments or upon redemption.

The indenture permits defeasance with respect to any series of debt securities even if a prior covenant defeasance has occurred with respect to the debt securities of that series. Following a defeasance, payment of the debt securities defeased may not be accelerated because of an event of default. Following a covenant defeasance, payment of the debt securities may not be accelerated by reference to the specified covenants affected by the covenant defeasance. However, if an acceleration were to occur, the realizable value at the acceleration date of the money and government obligations in the defeasance trust could be less than the principal and interest then due on the respective debt securities, since the required deposit in the defeasance trust would be based upon scheduled cash flows rather than market value, which would vary depending upon interest rates and other factors.

Under current United States federal income tax law, the defeasance contemplated in the preceding paragraphs would be treated as an exchange of the relevant debt securities in which holders of the debt securities might recognize gain or loss. In addition, the amount, timing and character of amounts that holders would be

required after the defeasance to include in income might be different from that which would be includible in the absence of the defeasance. Prospective investors are urged to consult their own tax advisors as to the specific consequences of a defeasance, including the applicability and effect of tax laws other than United States federal income tax laws.

Under current United States federal income tax laws, unless accompanied by other changes in the terms of the debt securities, covenant defeasance generally should not be treated as a taxable exchange.

Resignation and Removal of the Indenture Trustee; Deemed Resignation

The indenture trustee may resign at any time by giving written notice to us.

The indenture trustee may also be removed with respect to any series of debt securities by act of the registered holders of a majority in principal amount of the then outstanding debt securities of any such series.

No resignation or removal of the indenture trustee and no appointment of a successor indenture trustee will become effective until the acceptance of appointment by a successor indenture trustee in accordance with the requirements of the indenture.

Under some circumstances, we may appoint a successor indenture trustee and, if the successor accepts, the indenture trustee will be deemed to have resigned.

Governing Law

The indenture and the related debt securities will be governed by and construed in accordance with the laws of the State of New York.
