By the numbers: On completion, Vivmark Residential is expected to hold a pro forma equity market capitalisation of roughly $53 billion and an enterprise value of about $71 billion.

The merger remains subject to customary closing conditions, including shareholder approval, and the companies will keep operating independently under their existing names until it closes.

The signal: Benjamin Schall, AvalonBay's chief executive and the incoming CEO of Vivmark Residential, said the name reflects an ambition to set a higher standard for the rental housing experience. According to the companies, “viv” derives from the Latin vivere (“to live”) and “mark” signals quality and lasting impact.
