We give a first example of a (nonregular) extension with closed remainder which cannot be obtained as B-extension. Extensions with closed discrete remainders and extensions whose remainders are retract are mostly considered. We answer some open questions about separation properties and metrizability of B-extensions.}, number={2}, journal={Applied General Topology}, author={Caterino, Alessandro and Vipera, M.
