Eric Purington, Portfolio Manager for the aberdeen Global Income Infrastructure fund says that large-scale infrastructure investors have raised billions to pump into the big names in the sector, the smaller private-equity firms and the middle-market opportunities have struggled to bring in capital. That has created an opportunity that Purington has taken advantage of for the last few years and that he sees continuing, as the infrastructure space continues booming; middle-market opportunities grow and mature and really pay off when they become investment targets for those well-funded, big private-equity investors. Purington says this trend has persisted over the last few years, is not dependent on government issues or subject to as much political risk as other infrastructure ideas.
