The ticker EIP no longer belongs to any operating company. It belonged to the Eaton Vance Pennsylvania Municipal Bond Fund, a closed-end municipal bond fund managed by Eaton Vance Management in Boston, which ceased to exist as a standalone issuer when shareholders voted it into a larger municipal fund in the same family at the close of trading in January 2019.
The sequence that retired the ticker ran in about seven weeks. Shareholders approved the reorganization at a special meeting in late December 2018. A final pre-merger distribution of $0.0663 per share went payable in late January 2019 to clear out accumulated undistributed income. The exchange itself settled at a ratio of 1.034833791 shares of the acquiring fund for each EIP share.
Every load-bearing figure that survives for this name lives in the record of the former fund, a quarterly portfolio schedule as of year-end 2018 and a deregistration application filed in the spring of 2020. The central question for anyone still holding the ticker in a watchlist is not what the fund did next, but why a symbol that looked like an energy infrastructure equity in a screening tool actually pointed to a bond fund that no longer trades.
