I work for a yank company as well. Final salary pension.
  I let them make contributions but i do not make any additional ones. 
 I do 2 things with the cash i should be putting by for a pension. 
 Firstly i take up the right to buy company shares every month, for every share i buy the company matches it so i get my shares at 50% basically. 
 Secondly I stick my money in bricks and mortar and play the buy to let game. 
 When it comes time to retire i will sell my shares, flog the flats and bugger off with the profits to a sunny climate. 
 If the tax man wants to chase me for the capital gains tax he is more than welcome to try and find me.......
