Wealth Tax in Switzerland - seeking clarification

Does anyone have information on Wealth Tax that an expat has to pay, in Switzerland, on worldwide assets that they own ?  I understand that we have to pay about 1% of asset value, annually, as wealth tax, even if that assets is located or was earned outside fo switzerland. This came as a shock to us,last week.   

Specifically, we seek information on what assets are included in determining "wealth", and what assets are not necessary to declare for this purpose ?  For example, in my previous workplace, we did not have a pension plan; instead, the company gave us shares of company stock, that we are supposed to use to create our retirement income ( via selling or using dividends).  Does the market value of such stocks become a part of our assets, for the purpose of determining wealth tax ? If teh company had a pension plan, instead, it would have set aside assets to use as a source of revenue to pay my pension once I retired - but that asset would not be considered as assets that I own, for wealth tax purpose.
