Hi Victor/ Rusmin,
An idea came to mind to look at possibly toll road operators. Singapore used to have one CMPacific which was delisted not long ago. The dividends payout was good.
The link below (dated 2011) listed some of these stocks and Bangkok Expressway and Metro PCL BEM: SET is one of them. In Indonesia, a Google search revealed one Jasa Marga (Persero) IDX: JSMR

Toll road operators. I believe, have recurring revenue, but possible downside is high debt.
Would like your opinion on whether this category of stocks is worth looking at. Thanks.
