THE LORD ABBETT FAMILY OF FUNDS¹

Supplement dated March 28, 2018

to the Prospectuses and Statements of Additional Information

This supplement supersedes and replaces corresponding the prospectus and statement of additional information (“SAI”) supplement dated March 15, 2018.² You should read this supplement in conjunction with your Fund’s prospectus and SAI.

Effective March 15, 2018, the following information replaces the subsection of the prospectus titled “Choosing a Share Class – Additional Information about the Availability of Share Classes – Class A Shares” and supplements and supersedes any information to the contrary in each Fund’s prospectus and SAI.

Class A Shares. Class A shares are available for investment by retirement and benefit plans only under the following circumstances: (i) the retirement and benefit plans have previously invested in Class A shares of the Fund as of the close of business on December 31, 2015; (ii) the retirement and benefit plan investments are subject to a front-end sales charge and, with respect to retirement or benefit plans serviced by a recordkeeping platform, such recordkeeping platform is able to apply properly a sales charge on such investments by the plan; or (iii) the retirement and benefit plan investments are eligible for a Class A sales charge waiver under Appendix A to this prospectus. Class A shares remain available to retail non-retirement accounts, traditional and Roth IRAs, Coverdell Education Savings Accounts, SEPs, SARSEPs, SIMPLE IRAs, individual 403(b) plans, and 529 college savings plans.

Effective April 30, 2018, the following information replaces the row titled “Automatic Conversion” of the table in the subsection of the prospectus titled “Choosing a Share Class – Key Features of Share Classes – Class C Shares” and supplements and supersedes any information to the contrary in each Fund’s prospectus and SAI:

Class C Shares
Automatic Conversion	Automatic conversion into Class A shares the month following the tenth anniversary of purchase(*)

^(*) Effective April 30, 2018, Class C shares will convert automatically into Class A shares on the 25^th day of the month (or, if the 25th is not a business day, the next business day thereafter) following the tenth anniversary of the month on which the purchase order was accepted, provided that the Fund or the financial intermediary through which a shareholder purchased Class C shares has records verifying that the Class C shares have been held for at least ten years.

¹ Class A and C shares are not available in all Lord Abbett Funds. Please review your Fund’s prospectus and SAI to determine whether the Fund offers these share classes.

²This supplement does not supersede or affect the supplement to Lord Abbett Securities Trust’s prospectus dated March 15, 2018 concerning financial intermediary compensation.

Effective April 30, 2018, the following information is inserted in the SAI and supplements and supersedes any information to the contrary in each Fund’s prospectus and SAI:

Conversions of Class C Shares. Class C shares will convert automatically into Class A shares ten years after the date of purchase. When Class C shares that a shareholder acquired through a purchase or exchange convert, any other Class C shares that the shareholder acquired as reinvested dividends and distributions also will convert into Class A shares on a pro rata basis. Class C shares held through a financial intermediary in an omnibus account will be converted into Class A shares only if the intermediary can document that the shareholder has met the required holding period. It is the financial intermediary’s (and not the Fund’s) responsibility to keep records and to ensure that the shareholder is credited with the proper holding period. Not all financial intermediaries are able to track purchases to credit individual shareholders’ holding periods. In particular, group retirement plans held through third party intermediaries that hold Class C shares in an omnibus account may not track participant level share lot aging. Please consult with your financial intermediary about your eligibility to exercise this conversion privilege.

The following policies are added to “Appendix A: Intermediary-Specific Sales Charge Policies and Waivers” in each Fund’s prospectus as of the applicable date indicated below:
