precious jewellery (3.7%), and other unclassified transactions (18%). While Switzerland has a long tradition of manufacturing cars, there are currently no large-scale assembly line automobile manufacturers in the country. Tourism Switzerland has highly developed tourism infrastructure, especially in the mountainous regions and cities, making it a good market for tourism-related equipment and services. 14% of hotels were in Grisons, 12% each in the Valais and Eastern Switzerland, 11% in Central Switzerland and 9% in the Bernese Oberland. The ratio of lodging nights in relation to resident population ("tourism intensity", a measure for the relative importance of tourism to local economy) was largest in Grisons (8.3) and Bernese Oberland (5.3), compared to a Swiss average of 1.3. 56.4% of lodging nights were by visitors from abroad (broken down by nationality: 16.5% Germany, 6.3% UK, 4.8% USA, 3.6% France, 3.0% Italy) The total financial volume associated with tourism, including transportation, is estimated to CHF 35.5 billion (as of 2010) although some of this comes from fuel tax and sales of motorway vignettes. The total gross value added from tourism is 14.9 billion. Tourism provides a total of 144,838 full time equivalent jobs in the entire country. The total financial volume of tourist lodging is 5.19 billion CHF and eating at the lodging provides an additional 5.19 billion. The total gross value added of 14.9 billion is about 2.9% of Switzerland's 2010 nominal GDP of 550.57 billion CHF. Banking and finance In 2003, the financial sector comprised an estimated 11.6% of Switzerland's GDP and employed approximately 196,000 people (136,000 of whom work in the banking sector); this represents about 5.6% of the total Swiss workforce. Swiss neutrality and national sovereignty, long recognized by foreign nations, have fostered a stable environment in which the banking sector was able to develop and thrive. Switzerland has maintained neutrality through both World Wars, is not a member of the European Union, and was not even a member of the United Nations until 2002. Currently an estimated 28 percent of all funds held outside the country of origin (sometimes called "offshore" funds) are kept in Switzerland. In 2009 Swiss banks managed 5.4 trillion Swiss Francs. Most of the financial sector is centred in Zurich and Geneva. Zurich specialises in banking (UBS, Credit Suisse, Julius Baer) as well as insurance (Swiss Re, Zurich insurance), whilst Geneva specialises in wealth management (Pictet Group, Lombard Odier, Union Bancaire Privée), and commodity
