Explanations

It can be seen that the side cross section of a table for table tennis with the net on top and a jumping ping-pong ball above it are depicted in the logo. The “Table Tennis” with 11 letters in total are the two missing words in the logo.

On top of that the table’s legs are moved closer to each other to create a silhouette of a tall vertical rectangle symbolizing the skyscraper 200 Clarendon Street, previously known as John Hancock Tower – the tallest building in Boston and the state of Massachusetts.
