Independent Auditors' Report
The Board of Trustees and Stockholders,
Lord Abbett Securities Trust:
We have audited the accompanying statements of net assets of Lord Abbett
Securities Trust - Growth & Income Series, International Series, World
Bond-Debenture Series and Alpha Series as of October 31, 1999, the related
statements of operations and of changes in net assets and the financial
highlights for each of the periods presented. These financial statements and the
financial highlights are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at October
31, 1999 by correspondence with the custodian and brokers; where replies were
not received from brokers, we performed other auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Lord Abbett
Securities Trust - Growth & Income Series, International Series, World
Bond-Debenture Series and Alpha Series at October 31, 1999, the results of their
operations, the changes in their net assets and their financial highlights for
the respective periods presented, in conformity with generally accepted
accounting principles.
