Series 50 common mistakes
Series 50 · Understand the traps and how to avoid them.
Delivering a specific financing recommendation to a municipal entity client and recording only the conflict disclosures in the file, with no written analysis of why the recommended structure fits that issuer's objectives, resources, and constraints.
Candidates memorize the written-conflict-disclosure prong of MSRB Rule G-42 and treat disclosure as the whole of the fiduciary duty, so they never build the reasonable-basis analysis the rule also demands.
What to do instead
Before any recommendation goes out, write a one-page basis memo: client objectives, each alternative considered (including taking no action), relative costs and risks, and why the chosen structure wins. Treat that memo as a precondition to delivery, not follow-up paperwork.
Continuing to advise an issuer after learning that a swap dealer, underwriter, or other third party pays the firm compensation tied to the same transaction, reasoning that the client pays nothing extra so there is nothing to disclose.
Conflict training focuses on direct fee arrangements, so indirect and contingent compensation streams go unnoticed and untracked.
What to do instead
Build a revenue map for every engagement that lists all sources of compensation, direct and indirect, fixed and contingent. Apply Rule G-42(c) full and fair written disclosure to all material conflicts, obtain written client acknowledgment, and redo the analysis whenever the compensation structure changes.
Starting the analysis and giving informal structural advice to an issuer weeks before the written municipal advisory agreement is signed, treating the agreement as closing paperwork.
Clients push for immediate help and representatives assume a signed engagement letter can catch up later; regulation-by-contract feels like a formality rather than a condition precedent.
What to do instead
Adopt a hard gate: no advice, models, or recommendations until a written agreement covering scope of services, compensation, conflicts, and termination is executed. Communicate the gate to clients at first contact so the delay is expected.
Signing and sending an independent registered municipal advisor (IRMA) representation letter to an underwriter as a routine service, without confirming the firm actually meets the independence definition or clearing the letter through compliance.
Representatives see IRMA letters as a standard document that unlocks an underwriter exclusion, not as a substantive representation about the firm's ownership, affiliations, and compensation.
What to do instead
Before issuing any IRMA letter, verify against SEC Rule 15Ba1-1 that the firm is not controlled by or affiliated with an underwriter, is not receiving transaction-contingent compensation from the underwriter, and has no undisclosed conflict. Route every letter through compliance and log it.
Structuring a tax-exempt advance refunding of bonds issued after 2017, sizing the refunding issue to redeem the old bonds two or three years before the call date.
Study materials and real-world deal memory are full of pre-2018 advance refundings, so candidates apply the old rule to post-2017 issues without checking the tax status.
What to do instead
For bonds issued after December 31, 2017, treat tax-exempt advance refunding as unavailable; structure a current refunding within 90 days of the redemption date, or evaluate a taxable refunding if the savings justify it. Confirm the issue date and call provisions before modeling.
Reporting refunding 'savings' by subtracting total nominal debt service on the old bonds from total nominal debt service on the new bonds, then telling the issuer the deal clears its savings policy.
Nominal subtraction is arithmetically simple and produces a big, persuasive number, so candidates skip time-value discounting under exam time pressure.
What to do instead
Build period-by-period debt service for both sets of bonds, discount at the escrow reinvestment rate consistent with the issuer's policy, and present present value savings both in dollars and as a percentage of refunded par. State the discount rate and assumptions on the page.
Recommending an interest rate swap to hedge a variable-rate exposure without showing the issuer what it would cost to terminate the swap if rates move against the position, and without addressing who monitors the hedge after closing.
Attention goes to the headline benefit (synthetic fixed rate) and the candidates treat termination exposure as a remote tail event rather than a budgeted, ongoing risk.
What to do instead
Run scenario analysis at multiple rate levels and show the termination payment at each; disclose counterparty credit, basis, and remarketing/put risk; confirm the issuer has legal authority and a board-adopted swap policy; specify in the engagement who monitors, how often, and how collateral posting is handled.
Recommending how an issuer should invest bond proceeds or reserve funds and treating that recommendation as a routine banking courtesy outside the municipal advisory relationship.
Candidates associate municipal advisory work only with issuance, so proceeds investment feels like an operational afterthought rather than advice to a municipal entity.
What to do instead
Treat proceeds-investment recommendations as municipal advisory advice: document the issuer's permitted-investment constraints and state-law safe harbor analysis, evaluate provider credit and diversification, disclose any provider relationships or compensation, and record the basis for the recommendation.
Allowing a covered associate's $500 contribution to a city council candidate who votes on bond authorizations, and continuing to accept municipal advisory engagements from that city within two years of the contribution.
Candidates learn Rule G-37 as a broker-dealer rule and do not apply it to municipal advisors, and they overgeneralize the small-contribution exception without checking its conditions.
What to do instead
Apply Rule G-37 to the municipal advisory business: maintain a contribution log, pre-clear political contributions, and impose the two-year ban on new business with the issuer. Rely on the de minimis exception only where the amount is within the rule's limit per election per candidate and the contributor is not entitled to vote for that candidate.
Operating as a municipal advisor with no written supervisory procedures tailored to municipal advisory work and no principal reviewing recommendations before they reach the issuer.
Representatives think of compliance manuals as generic firm documents written for the broker-dealer side, and small advisory firms assume one experienced professional needs no oversight structure.
What to do instead
Adopt Rule G-44 supervisory procedures that specifically cover engagement approval, review of recommendations and the basis for them, conflict review, political contribution pre-clearance, gift and entertainment limits, and an annual compliance review; designate a principal responsible for review and document each review.
