Walter Putnam: Northwestern Advisor Faced $65K Complaint

A recent, denied investor complaint against Tampa, Florida financial advisor Walter Putnam (CRD# 1274433) alleged that he recommended an unapproved investment. Financial Industry Regulatory Authority records show that he is registered as a broker with Northwestern Mutual Investment Services.

Mr. Putnam’s BrokerCheck report discloses two investor complaints. The most recent, filed in June 2026, alleged that as a representative of Northwestern Mutual Investment Services, he solicited funds for an investment in a private company which had not been approved by Northwestern Mutual. The complaint alleged damages of $65,000 and was denied by the firm.

A second investor complaint, filed in 2010, alleged that as a representative of Northwestern Mutual, he provided misleading information in connection with a variable life insurance policy. The complaint alleged unspecified damages and was denied by the firm.

For reference, FINRA Rule 3280 prohibits brokers like Mr. Putnam from engaging in private securities transactions—that is, transactions involving products unapproved by their firm—without providing prior written notice to their member firm, and, in cases where they have received or may receive selling compensation for the transaction, without receiving written approval from their member firm. Private securities transactions can involve many risks for the investor, as they may involve investments for which the firm has not conducted due diligence. Brokers who recommend private securities transactions may be held liable in the event of losses.

According to the Financial Industry Regulatory Authority, Walter Putnam holds 30 years of securities industry experience. Based in Tampa, Florida, he has been registered as a broker with Northwestern Mutual Investment Services since 1996. His past registrations include Robert W. Baird. His credentials include the passage of five securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the General Securities Representative Examination, or Series 7; the Investment Company Products/Variable Contracts Representative Examination, or Series 6; the Uniform Investment Adviser Law Examination, or Series 65; and the Uniform Securities Agent State Law Examination, or Series 63. He holds 26 state licenses. (Information current as of August 30, 2026.)
