摘要:
A pivoting soccer goal mounted on a turntable can rotate so that a ball directed at the goal from nearly any angle will rotate the goal so that the ball will go into the goal. The goal can be seated in a standard golf cup and so can be used on a golf course. In another embodiment, the pivoting soccer goal can be mounted on a mat and set on any suitable field without the need for any holes in the ground.

A system and method for conducting ADR swaps is disclosed where ADR swap requests are read into a queue. The swap requests are then matched by security type. For example, a swap request can be made to exchange ADRs in a first security for underlying shares in the same security. The matching swap requests are then executed and the ADRs and underlying shares are exchanged.
