Item 1: Proxy Voting Record

Registrant: Putnam Municipal Opportunities Trust

The fund did not vote proxies relating to portfolio securities during the period covered by this report.


Any ballot marked 'Abstain' is considered to have been voted. Ballots marked 'Abstain' are considered to have been voted against management's recommendation if management's recommendation is 'For' or 'Against,' and for management’s recommendation if management’s recommendation is ‘Abstain.’ Where management has recommended that shareholders 'Abstain' from voting on a ballot item, a ballot marked 'For' or 'Against' is considered to have been voted against management's recommendation to 'Abstain.'

Where management has made no recommendation on a ballot item, 'NA' is used to indicate that there is no management recommendation that a shareholder may vote 'For' or 'Against.'
