**FORWARD-LOOKING STATEMENTS** 

This prospectus and any applicable prospectus supplement, including the documents incorporated by reference herein and therein, and other statements that we may make, may contain forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, with respect to our financial results and outlook, capital adequacy, dividend policy and share repurchase program, accounting estimates and assumptions, credit quality including allowance levels, future pension plan contributions, effective tax rate, anticipated expense levels, contingent liabilities, acquisitions, strategies, market and industry trends, and expectations regarding the impact of accounting pronouncements and legislation, and all other statements that do not relate to historical facts.

Forward-looking statements are identified typically by words or phrases such as "believe," "expect," "anticipate," "intend," "estimate," "project," "likely," "plan," "goal," "target," "strategy," and similar expressions or future or conditional verbs such as "may," "will," "should," "would," and "could." You should read carefully the risk factors described in "Risk Factors" herein and in the documents incorporated by reference in this prospectus and the applicable prospectus supplement for a description of certain risks that could, among other things, cause our actual results to differ from these forward-looking statements.

Forward-looking statements are based on our current beliefs and expectations of future events or future results, and involve risks and uncertainties that are difficult to predict and subject to change. These statements are also based on assumptions about many important factors, including:

**DESCRIPTION OF THE DEBT SECURITIES** 

We may offer debt securities, which may be senior debt securities or subordinated debt securities and may be convertible or nonconvertible, as well as secured or unsecured. The following description briefly sets forth certain general terms and provisions of the debt securities. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to the debt securities, will be described in the applicable prospectus supplement.

Unless otherwise specified in the applicable prospectus supplement, our debt securities will be issued in one or more series under the indenture dated as of May 8, 2017, as amended or supplemented from time to time, between us and The Bank of New York Mellon Trust Company, N.A., acting as a trustee, a copy of which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. The terms of the debt securities will include those set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939, or the TIA. You should read the summary below, the applicable prospectus supplement and the provisions of the indenture and indenture supplement, if any, in their entirety before investing in our debt securities.

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any additions or changes in the defaults and events of default applicable to the particular debt securities being
issued;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the currency, currencies or currency units in which the purchase price for, the principal of and any premium and

may modify, amend, supplement or delete any of the terms of the indenture with respect to such series of debt securities).

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series or any other series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, may constitute a single series of securities under the indenture.

We will describe in the applicable prospectus supplement any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars. In addition, debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. We will describe in the applicable prospectus supplement information as to the methods for determining the amount of principal or interest, if any, payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked.

U.S. federal income tax consequences and special considerations, if any, applicable to any such series will be described in the applicable prospectus supplement. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

**Registration and Transfer** 

Unless otherwise indicated in the applicable prospectus supplement, we will issue each series of debt securities in fully registered form without coupons and in denominations of $2,000 and any integral multiples of

------

##### [**Table of Contents**](#toc)
$1,000 in excess thereof. Subject to the limitations provided in the indenture and in the applicable prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the office or agency maintained by us for such purpose, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

**Payment and Place of Payment** 

Unless otherwise indicated in the applicable prospectus supplement, we will pay principal of and any premium and interest on the debt securities to holders of record at the office or agency maintained by us for such purpose.

**Events of Default** 

Unless otherwise indicated in the applicable prospectus supplement, an event of default under the indenture with respect to any series of debt securities will mean any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay any installment of interest on any debt security of such series when due, if such failure
continues unremedied for 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay the principal and premium, if any, of any debt security of such series when due, either at
maturity, upon redemption, by declaration or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay any sinking fund installment on any debt security of such series when due, if such failure
continues unremedied for 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure on our part to perform any other obligation contained in the indenture for the benefit of such series
which continues for 90 days after written notice to us by the trustee or to us and the trustee by the holders of at least 25% in outstanding principal amount of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• occurrence of certain events of bankruptcy, insolvency or reorganization; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other event of default provided with respect to the debt securities of such series.

If an event of default under the indenture occurs and is continuing for any series of debt securities, other than an event of default resulting from a bankruptcy, insolvency or reorganization of the Corporation, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of all the debt securities of that series, or such amount provided for in the debt securities of that series, and all accrued but unpaid interest on all the debt securities of that series to be due and payable immediately. The debt securities will automatically be accelerated upon the occurrence of an event of default resulting from a bankruptcy, insolvency or reorganization of the Corporation.

In the case of a default in the payment of interest or principal, or premium, if any, we will be required, upon the demand of the trustee, to pay, for the benefit of the holders of the debt securities, the whole amount then due and payable on such debt securities with interest on any overdue principal, and premium, if any, and, to the extent that payment of such interest shall be legally enforceable, on any overdue interest, at the rate or rates prescribed in such debt securities.

If we fail to pay such amounts upon demand, the trustee may institute any action or proceeding at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Corporation or any other obligor upon the debt securities of such series, and collect the moneys adjudged or decreed to be payable out of the property of the Corporation or any other obligor upon the debt securities of such series, wherever situated, in the manner provided by law.

The holders of a majority in principal amount of the outstanding debt securities of a series may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any

------

##### [**Table of Contents**](#toc)
trust or power conferred on the trustee with respect to debt securities of that series, provided that any such direction is not in conflict with the indenture, could lawfully be taken, would not be unduly prejudicial to holders not joining in such direction and would not involve the trustee in personal liability, and the trustee may take any other action deemed proper by the trustee that is not inconsistent with such direction. Subject to the provisions of the indenture relating to the duties of the trustee, before proceeding to exercise any right or power under the indenture at the direction of the holders, the trustee is entitled to receive from those holders security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in complying with any direction.

No holder of any debt security of any series will have the right to institute any action, suit or proceeding with respect to an event of default, unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• that holder previously gives to the trustee written notice of the event of default with respect to debt
securities of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holders of not less than 25% in principal amount of the outstanding debt securities of that series also make
a written request to the trustee to take action in respect of the matter complained of;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holder offers the trustee security or indemnity satisfactory to the trustee against the costs, expenses and
liabilities to be incurred;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the trustee has not received from the holders of a majority in principal amount of the outstanding debt
securities of that series a direction inconsistent with such request; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the trustee fails to institute such action, suit or proceeding within 60 days.

However, any holder of a debt security has the absolute right to institute suit for any defaulted payment after the due dates for payment under that debt security.

We are required to furnish an officer's certificate to the trustee each year that states, to the knowledge of the certifying officer, whether we have complied with all conditions and covenants under the terms of the indenture, and, in the event of any default under the indenture, specifying such default and the nature and status thereof to the extent of the certifying officer's knowledge.

**Modification and Waiver** 

***Modification***

We and the trustee may, with the consent of holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series affected, modify and amend the indenture; however, without the consent of each holder of any debt security affected, we may not amend or modify the indenture to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• extend the stated maturity of the principal of, or any installment of interest on, such debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount of or the interest on or any premium payable upon the redemption of such debt
security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the amount of principal of an original issue discount security payable upon acceleration of its maturity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the place of payment where or the currency in which the principal of and premium, if any, or interest on
any debt security is denominated or payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• impair the holder's right to institute suit for the enforcement of any payment on any debt security after
the stated maturity or redemption date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage in principal amount of debt securities of any series, the consent of whose holders is

certain past defaults or certain covenants, except to increase the required percentage to effect such action or to provide that certain other provisions may not be modified or waived without the consent of all of the holders of each debt security
affected.

We and the trustee may modify and amend the indenture without the consent of the holders of the debt securities for specified purposes, including, among other things, to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change or eliminate provisions of the indenture provided that such change or elimination becomes effective only

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• secure the debt securities of any series or release any collateral or lien securing debt securities of any series
in accordance with the terms thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evidence any changes to the indenture in conjunction with the resignation, removal or merger of the trustee in
accordance with the terms of the indenture;

securities of a series previously authorized or add to the conditions, limitations or restrictions on the issuance of any debt securities of any series.

***Waiver of Default***

The holders of a majority in principal amount of the outstanding debt securities of any series generally may, on behalf of the holders of all the debt securities of that series, waive an event of default under the indenture with respect to that series and the consequences thereof. However, a default in the payment of the principal of, or premium, if any, or any interest on, any of the debt securities of that series cannot be so waived.

**Merger, Consolidation and Sale of Assets** 

The Corporation may not consolidate with or merge into any other person or sell, convey, transfer or lease all or substantially all its assets to any other person, unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the person formed by such consolidation or into which the Corporation is merged, or to which such sale,
conveyance, transfer or lease is made, expressly assumes, pursuant to a supplemental indenture, the due and punctual payment of the principal of and interest and premium, if any, on all of the debt securities under the indenture, according to their
tenor, and the due and punctual performance and observance of all other obligations to the holders of debt securities and the trustee under the indenture or the debt securities to be performed or observed by the Corporation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• immediately after giving effect to such consolidation, merger, sale, conveyance, transfer or lease, no default
shall have occurred and be continuing under the indenture.

The second bullet above shall not apply to: (i) any sale, conveyance, transfer or lease between or among the Corporation and one or more of its wholly-owned subsidiaries; (ii) any merger of the Corporation into any wholly-owned subsidiary of the Corporation; or (iii) any merger of the Corporation into an affiliate of the Corporation for the purpose of reincorporating or reorganizing.

The indenture provides that the person formed by such consolidation or into which the Corporation is merged or to which such sale, conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Corporation under the indenture with the same effect as if such successor person had been named as the Corporation in the indenture. In the event of a succession in compliance with this covenant, except in the case of a lease, the predecessor shall be relieved of and discharged from all of its obligations and covenants under the indenture and the debt securities.

**Discharge and Covenant Defeasance** 

Unless otherwise specified in the applicable prospectus supplement, we may discharge all of our obligations with respect to the debt securities of any series at any time, and we may also be released from our obligations under certain covenants that are described in the indenture with respect to such debt securities, if any, and elect not to comply with those sections and obligations without creating an event of default. Discharge under the first procedure is called "discharge" and under the second procedure is called "covenant defeasance."

Discharge or covenant defeasance may be effected only if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we irrevocably deposit with the trustee money or U.S. government obligations or a combination thereof, as trust
funds in trust in an amount sufficient to pay and discharge each installment of principal of, premium, if any, and interest on, all outstanding debt securities of the applicable series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• no default under the indenture with respect to such series has occurred and is continuing on the date of such
deposit; and

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we deliver to the trustee an opinion of counsel to the effect that the holders of the applicable series of debt
securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such discharge or covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as
would have been the case if such discharge or covenant defeasance had not occurred and, in the case of a discharge, such opinion is accompanied by a ruling to that effect received from or published by the U.S. Internal Revenue Service.

**Satisfaction and Discharge** 

Unless otherwise specified in the applicable prospectus supplement, we may terminate our obligations with respect to the debt securities of any series not previously delivered to the trustee for cancellation when all such securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• have become due and payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• will become due and payable at their stated maturity within one year; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are to be called for redemption within one year under arrangements satisfactory to the trustee for giving notice
of redemption;

by depositing with the trustee or paying agent, as trust funds in trust for that purpose, an amount sufficient to pay and discharge the entire indebtedness on such debt securities.

**Subordination** 

The terms of any series of debt securities under the indenture may provide that such series will be subordinated in right of payment to all senior indebtedness, as described in the applicable prospectus supplement.

**Global Securities** 

Unless we inform you otherwise in the applicable prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

**Governing Law** 

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

**PLAN OF DISTRIBUTION** 

We may offer and sell the securities described in this prospectus through underwriters, through dealers, through agents, directly to purchasers, through or in connection with hedging transactions, or through any combination of such methods of sale and may do so at a fixed price or prices (which may be changed), at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices.

Each time we sell securities, we will provide a prospectus supplement that will describe the method of distribution of the securities and name any underwriter, dealer or agent involved in the offer and sale. The prospectus supplement will also set forth the terms of the offering, including the purchase price of the securities and the proceeds we will receive from the sale of the securities, any underwriting discounts and other items constituting underwriters' compensation related to the offering, public offering or purchase price and any discounts or commissions allowed or paid to dealers, any commissions allowed or paid to agents and any securities exchanges on which the securities may be listed.

**Distribution Through Underwriters** 

We may offer and sell securities from time to time to one or more underwriters who would purchase the securities as principal for resale to the public, either on a firm commitment or best efforts basis. If the securities are sold to underwriters, we will execute an underwriting agreement with them at the time of the sale and we will name them in the applicable prospectus supplement. In connection with these sales, the underwriters will receive compensation in the form of underwriting commissions, which will be paid by us. The underwriters also may receive commissions from purchasers of securities for whom they may act as agent. Unless we specify otherwise in the applicable prospectus supplement, the underwriters will not be obligated to purchase the securities unless the conditions set forth in the underwriting agreement are satisfied, and if the underwriters purchase any of the securities, they will be required to purchase all of the offered securities. The underwriters may acquire the securities for their own account and may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or varying prices determined at the time of sale. The underwriters may sell the offered securities to or through dealers, and those dealers may receive discounts, concessions or commissions from the underwriters as well as from the purchasers for whom they may act as agent. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

**Distribution Through Dealers** 

We may offer and sell securities from time to time to one or more dealers who would purchase the securities as principal. The dealers then may resell the offered securities to the public at fixed or varying prices to be determined by the dealers at the time of resale. We will set forth the names of the dealers and the terms of the transaction in the applicable prospectus supplement.

**Distribution Through Agents** 

We may offer and sell securities through agents that become parties to a distribution agreement. We will name any agent involved in the offer and sale and describe any commissions payable by us in the applicable prospectus supplement. Unless we specify otherwise in the applicable prospectus supplement, the agent will be acting on a best efforts basis during the appointment period.

**Direct Sales** 

We may sell directly to, and solicit offers directly from, one or more purchasers without the involvement of any underwriters, dealers or agents. We will describe the terms of any sales of this kind in the prospectus supplement relating to the offer.

##### [**Table of Contents**](#toc)
**General** 

In connection with offerings made through underwriters or agents, we may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of securities. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or a post-effective amendment to the registration statement of which this prospectus forms a part.

We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus.

If indicated in the applicable prospectus supplement, we will authorize underwriters, dealers or agents to solicit offers by certain institutional investors to purchase securities from us pursuant to contracts providing for payment and delivery at a future date. In all cases, these purchasers must be approved by us. Unless otherwise set forth in the applicable prospectus supplement, the obligations of any purchaser under any of these contracts will not be subject to any conditions except that (i) the purchase of the securities must not at the time of delivery be prohibited under the laws of any jurisdiction to which that purchaser is subject and (ii) if the securities are also being sold to underwriters, we must have sold to these underwriters the securities not subject to delayed delivery. Underwriters and other agents will not have any responsibility in respect of the validity or performance of these contracts.

Underwriters, dealers, agents and other persons may be entitled under agreements which may be entered into with us to indemnification against and contribution toward certain civil liabilities, including liabilities under the Securities Act and to be reimbursed by us for certain expenses.

Subject to any restrictions relating to debt securities in bearer form, any securities initially sold outside the United States may be resold in the United States through underwriters, dealers or otherwise.

Securities may represent a new issue of securities with no established trading market. Any underwriters to whom offered securities are sold by us for public offering and sale may make a market in such securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time.

The anticipated date of delivery of the securities offered by this prospectus will be described in the applicable prospectus supplement. The securities offered by this prospectus may or may not be listed on a national securities exchange or a foreign securities exchange. No assurance can be given as to the liquidity or activity of any trading in the offered securities.

In connection with an underwritten offering, the underwriters may engage in over-allotment, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act.

Over-allotment involves sales in excess of the offering size, which creates a short position for the underwriters. The underwriters may enter bids for, and purchase, securities in the open market in order to stabilize the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover short positions. In addition, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions, or otherwise. These activities may cause the price of the securities to be higher than it would otherwise be. Those activities, if commenced, may be discontinued at any time.

Under Rule 15c6-1 of the SEC under the Exchange Act as currently in effect, trades in the secondary market generally are required to settle on the first business day following the trade date unless the parties to any such trade expressly agree otherwise. It is possible that we or any underwriter, dealer or agent selling our securities in reliance on this prospectus will elect to settle the sale of securities offered and sold in reliance on this prospectus in accordance with a longer than standard settlement cycle, in which case the alternative settlement cycle to be used will be specified in the applicable prospectus supplement. In the event such a longer than standard settlement cycle is elected, purchasers who desire to effect a trade of the securities they purchase at any time prior to the business day preceding the issue date of such securities will be required to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Any such purchasers of securities who desire to trade on any such day should consult their own advisers regarding the date on which such purchasers' trades may be settled.

The underwriters, agents, dealers and their affiliates may engage in financial or other business transactions with us and our subsidiaries in the ordinary course of business.

**Item 15.** **Indemnification of Directors and Officers.** <br>

Section 102 of the Delaware General Corporation Law allows a corporation to eliminate the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except in cases where the director breached his or her duty of loyalty to the corporation or its stockholders, failed to act in good faith, engaged in intentional misconduct or a knowing violation of the law, willfully or negligently authorized the unlawful payment of a dividend or approved an unlawful stock redemption or repurchase or obtained an improper personal benefit. Article Eleventh of the registrant's Restated Certificate of Incorporation contains a provision which eliminates directors' personal liability as set forth above.

Article Eighth of the registrant's Restated Certificate of Incorporation provides in effect that the registrant will indemnify its directors and officers to the fullest extent permitted by Delaware law. Section 145 of the Delaware General Corporation Law provides that a Delaware corporation has the power to indemnify its directors, officers, employees and agents in certain circumstances. Subsection (a) of Section 145 of the Delaware General Corporation Law empowers a corporation to indemnify any director, officer, employee or agent, or former director, officer, employee or agent, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding provided that such director, officer, employee or agent acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, provided that such director, officer, employee or agent had no reasonable cause to believe that his or her conduct was unlawful.

Subsection (b) of Section 145 of the Delaware General Corporation Law empowers a corporation to indemnify any director, officer, employee or agent, or former director, officer, employee or agent, who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys' fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except

------

##### [**Table of Contents**](#toc)
that no indemnification may be made in respect of any claim, issue or matter as to which such person has been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought determines that despite the adjudication of liability such person is fairly and reasonably entitled to indemnity for such expenses which the court deems proper.

Section 145 further provides that to the extent that a director or officer or employee of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, he or she will be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith.

The registrant has in effect insurance policies for general officers' and directors' liability insurance covering all of the registrant's officers and directors.

In connection with an offering of the securities registered hereunder, the registrant may enter into an underwriting agreement which may provide that the underwriters are obligated, under certain circumstances, to indemnify directors, officers and controlling persons of the registrant against certain liabilities, including liabilities under the Securities Act.

**Item 17.** **Undertakings.** <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this
registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in
volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus
filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) to include any material information with respect to the plan of distribution not previously disclosed in the
registration statement or any material change to such information in the registration statement;

*provided, however,* that paragraphs (a)(1)(i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to remove from registration by means of a post-effective amendment any of the securities being registered which
remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) that, for the purpose of determining liability under the Securities Act to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the
registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration
statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and
included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule
430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that
prospectus relates, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof. *Provided, however*, that no statement made in a registration statement or prospectus that is part of the
registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or

------

##### [**Table of Contents**](#toc)
prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) that, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in
the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the
securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such
securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be
filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or
used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the portion of any other free writing prospectus relating to the offering containing material information about
the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the
Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial *bona fide* offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors,
officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: <u>Registration Statement on Form S-3</u> 

Ladies and Gentlemen:

We refer to the Registration Statement on Form S-3 (the "<u>Registration Statement</u>") being filed by Northern Trust Corporation, a Delaware corporation (the "<u>Company</u>"), with the Securities and Exchange Commission (the "<u>SEC</u>") under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), relating to the registration of up to $1,500,000,000 principal amount of debt securities of the Company (the "<u>Securities</u>"). Unless otherwise specified in the applicable prospectus supplement, the Securities will be issued under the indenture, dated as of May 8, 2017 (as amended or supplemented from time to time, the "<u>Indenture</u>"), by and between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the "<u>Trustee</u>").

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

We have examined the Registration Statement and the exhibits thereto, the certificate of incorporation of the Company, as amended to the date hereof (the "<u>Charter</u>"), the bylaws of the Company, as amended to the date hereof (the "<u>Bylaws</u>"), and the resolutions adopted by the board of directors of the Company (the "<u>Board</u>") relating to the approval of the filing of the Registration Statement and the issuance of the Securities to be registered thereunder. We have also examined originals, or copies of originals certified to our satisfaction, of such agreements, documents, certificates and statements of the Company and others, and have examined such questions of law, as we have considered relevant and necessary as a basis for this opinion letter. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all persons and the conformity with the original documents of any copies thereof submitted to us for examination. As to facts relevant to the opinions expressed herein, we have relied upon without independent investigation or verification, and assumed the accuracy and completeness of, certificates, letters and oral and written statements and representations of public officials and officers and other representatives of the Company.

Based on and subject to the foregoing and the other limitations, qualifications and assumptions set forth herein, we are of the opinion that:

------

Northern Trust Corporation

October 22, 2025

The Securities of each series covered by the Registration Statement will constitute valid and binding obligations of the Company when: (i) the Registration Statement, as finally amended (including any necessary post-effective amendments), shall have become effective under the Securities Act and the Indenture (including any necessary supplemental indenture) shall have been qualified under the Trust Indenture Act of 1939, as amended; (ii) a prospectus supplement with respect to such series of the Securities shall have been filed with the SEC in compliance with the Securities Act and the rules and regulations thereunder; (iii) all necessary corporate action shall have been taken by the Company to authorize the form, terms, execution, delivery, performance, issuance and sale of such series of the Securities as contemplated by the Registration Statement, the prospectus supplement relating to such Securities and the Indenture and to authorize the execution, delivery and performance of a supplemental indenture or officers' certificate establishing the form and terms of such series of the Securities as contemplated by the Indenture; (iv) a supplemental indenture or officers' certificate establishing the form and terms of such series of the Securities shall have been duly executed and delivered by the Company and the Trustee (in the case of such a supplemental indenture) or by duly authorized officers of the Company (in the case of such an officers' certificate), in each case in accordance with the provisions of the Charter**,** the Bylaws, final resolutions of the Board or a duly authorized committee thereof and the Indenture; and (v) the certificates evidencing the Securities of such series shall have been duly executed and delivered by the Company, authenticated by the Trustee and issued, all in accordance with the Charter, the Bylaws, final resolutions of the Board or a duly authorized committee thereof, the Indenture and the supplemental indenture or officers' certificate, as the case may be, establishing the form and terms of the Securities of such series, and shall have been duly delivered in accordance with the applicable definitive purchase, underwriting or similar agreement to the purchasers thereof against payment of the agreed consideration therefor.

Our opinions are subject to bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, fraudulent transfer and other similar laws relating to or affecting creditors' rights generally and to general equitable principles (regardless of whether considered in a proceeding in equity or at law), including concepts of commercial reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief. Our opinion is also subject to (i) provisions of law which may require that a judgment for money damages rendered by a court in the United States of America be expressed only in United States dollars, (ii) requirements that a claim with respect to any Securities or other obligations that are denominated or payable other than in United States dollars (or a judgment denominated or payable other than in United States dollars in respect of such claim) be converted into United States dollars at a rate of exchange prevailing on a date determined pursuant to applicable law and (iii) governmental authority to limit, delay or prohibit the making of payments outside of the United States of America or in a foreign currency.

For the purposes of this letter, we have assumed that, at the time of the issuance, sale and delivery of any of the Securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Securities being offered will be issued and sold as contemplated in the Registration Statement and the
prospectus supplement relating thereto;

------

Northern Trust Corporation

October 22, 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the execution, delivery and performance by the Company of the Indenture and each indenture supplement to the
Indenture, as applicable, and the issuance sale and delivery of the Securities will not (A) contravene or violate the Charter or Bylaws, (B) violate any law, rule or regulation applicable to the Company, (C) result in a default under
or breach of any agreement or instrument binding upon the Company or any order, judgment or decree of any court or governmental authority applicable to the Company, or (D) require any authorization, approval or other action by, or notice to or
filing with, any court or governmental authority (other than such authorizations, approvals, actions, notices or filings which shall have been obtained or made, as the case may be, and which shall be in full force and effect);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the authorization thereof by the Company, as the case may be, will not have been modified or rescinded, and
there will not have occurred any change in law affecting the validity, legally binding character or enforceability thereof; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the Charter and the Bylaws, each as currently in effect, will not have been modified or amended and will be in
full force and effect.

We have further assumed that each Security and each supplemental indenture will be governed by the laws of the State of New York.

With respect to each instrument or agreement referred to in or otherwise relevant to the opinions set forth herein (each, an "<u>Instrument</u>"), we have assumed, to the extent relevant to the opinions set forth herein, that (i) each party to such Instrument (if not a natural person) was duly organized or formed, as the case may be, and was at all relevant times and is validly existing and in good standing under the laws of its jurisdiction of organization or formation, as the case may be, and had at all relevant times and has full right, power and authority to execute, deliver and perform its obligations under such Instrument; (ii) such Instrument has been duly authorized, executed and delivered by each party thereto; and (iii) such Instrument was at all relevant times and is a valid, binding and enforceable agreement or obligation, as the case may be, of, each party thereto.

This opinion letter is limited to the laws of the State of New York (excluding the securities laws of the State of New York). We express no opinion as to the laws, rules or regulations of any other jurisdiction, including, without limitation, the federal laws of the United States of America or any state securities or blue sky laws.

We hereby consent to the filing of this opinion letter as an exhibit to the Registration Statement and to all references to our Firm included in or made a part of the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.
