Christopher R. Bohane, assistant secretary of Aberdeen Municipal Income Fund, submitted a Form 4 that lists no transactions, according to the SEC information supplied for this report. The source identifies the fund with ticker MFM. It provides no purchase, sale or other transaction to describe, and no associated quantity, execution price or transaction date.

The source publication timestamp is September 29, 2026, at 16:09:49 UTC. That timestamp identifies publication of the source item; it does not establish when any securities transaction occurred. The supplied information also indicates that the filing does not identify a Rule 10b5-1 trading plan.

Those are the available details about this particular disclosure. The supplied summary contains no holdings balance, transaction table, explanatory footnotes or account of why the form was submitted. It therefore does not establish whether Bohane owns fund shares, whether any ownership position changed outside this record, or whether additional explanation appears in the full document.

How Form 4 disclosures work

Form 4 is part of the SEC’s system for disclosing securities ownership and changes in ownership by people subject to Section 16 of the Securities Exchange Act. That system generally covers directors, certain officers and beneficial owners of more than 10% of a covered class of equity securities. The SEC is the federal agency responsible for administering these disclosure rules.

A Form 4 ordinarily reports a change in beneficial ownership. Most reportable transactions must be disclosed within two business days, although exceptions apply. The form can cover more than an open-market purchase or sale: awards, gifts, option exercises and other ownership changes may also appear, with transaction codes distinguishing their nature.

A typical transaction entry identifies the security, the transaction date, the amount acquired or disposed of and, where applicable, the price. Separate information addresses securities owned after the transaction and whether ownership is direct or indirect. Footnotes can explain matters such as trusts, shared ownership or the terms of an award.

None of those transaction details is available here. “No transactions” is the reported content of this disclosure; it is not a stated trade size of zero shares at a price of zero dollars. There is also no disclosed transaction date to substitute for the publication timestamp.

What the trading-plan notation covers

Rule 10b5-1 provides a framework under which a qualifying trading arrangement can offer an affirmative defense against insider-trading liability. Such arrangements can establish trading instructions in advance, subject to conditions intended to separate those instructions from later possession of material nonpublic information.

Form 4 includes a checkbox addressing whether a reported transaction was made under an arrangement intended to satisfy that rule’s affirmative-defense conditions. The absence of an identified plan in this summary does not supply a trading motive, establish wrongdoing or describe Bohane’s broader trading arrangements. Here, the summary reports no transaction in the first place.

What to watch

The full SEC filing, including any remarks and footnotes, is the document to consult for further explanation. Any subsequent amendment would also need to be read on its own terms. The supplied summary establishes no future trade or scheduled ownership change.
