LORD ABBETT GLOBAL FUND, INC.

Lord Abbett Developing Local Markets Fund

Lord Abbett Global Allocation Fund

Supplement dated December 23, 2009

to the Prospectus and

Statement of Additional Information dated May 1, 2009

(All Share Classes)

Effective March 31, 2010, each Fund will no longer offer Class B shares, as follows:

Effective March 31, 2010 (the “Effective Date”), each Fund will no longer make its Class B shares available for purchase by new or existing investors. As of the Effective Date, Class B shares will only be issued: (i) upon the exchange of Class B shares from another Lord Abbett Fund; or (ii) to purchase shares in connection with a reinvestment of a dividend and/or capital gain distribution. Any purchase orders for Class B shares (other than for an exchange or a distribution reinvestment) received by the Funds (or their authorized agents) after 4:00 p.m. Eastern time on the Effective Date will be deemed to be a purchase order for Class A shares and would be subject to any applicable Class A sales charge.

After the Effective Date, Class B shareholders who participate in automatic investment programs will no longer be able to make automatic investments into Class B shares. Shareholders that want to continue their participation in automatic investment programs must make an election prior to the Effective Date to change their automatic investments to purchase either Class A or Class C shares. If we receive no election from a shareholder before the Effective Date regarding their automatic investment program, the program will terminate on the Effective Date.

Shareholders owning Class B shares as of the Effective Date may continue to hold those shares (and any Class B shares acquired after the Effective Date pursuant to an exchange or distribution reinvestment). As described in each Fund’s Prospectus, Class B shares will continue to be subject to any applicable contingent deferred sales charge and automatically will convert to Class A shares after approximately 8 years from the date of purchase.

Effective December 23, 2009, the following replaces the subsections titled “The Fund – Management – Portfolio Managers,” and “The Fund – Management – Developing Local Markets Fund” in the Prospectus:

Portfolio Managers. For the Developing Local Markets Fund, the Fund is managed by a team of experienced portfolio managers responsible for investment decisions together with a team of research analysts who provide country, industry, sector and macroeconomic research and analysis. For the Global Allocation Fund, Lord Abbett’s Asset Allocation Committee oversees and reviews the allocation and investment of the Fund’s assets in the underlying funds. The Statement of Additional Information contains additional information about portfolio manager compensation, other accounts managed, and ownership of Fund shares.
