Omaisuudenhoitoyhtiö Arsenal: Omaisuudenhoitoyhtiö Arsenal Oy ("Asset Management Corporation Arsenal") is a corporation founded by the Government of Finland for management of assets.  Arsenal was founded after the early 1990s recession in 1993 as a response to the nationalization of failed banks, mainly Säästöpankki and STS Bank.  (The contribution of the Säästöpankki group to the total damages to the government was 96%.)  The defaulted debts led to a large amount property being passed to the government as collateral, with concomitant bankruptcy court cases where the state had an interest.  In 1994, Arsenal held 4.822 million euros of assets and had 12.684 customers.  In 1999, the business managing the real estate collateral was spun off as Kapiteeli Oyj, which was bought by Sponda in 2006.  (Sponda was also founded as a result of the same crisis around real estate and stocks from the collapsed SKOP Bank, but since 2012 has had no government ownership.)  Most of the remaining collateral was sold between 2000 and 2003.  In 2003, Arsenal voluntarily started liquidation proceedings.  As of May 2013, Arsenal had 121 debtors and 28 court cases ongoing, and kept four employees.

Thousands of German-Argentines have become professionals and technicians like doctors, bureaucrats, teachers and soldiers.  They founded German schools such as the Hölters Schule and German-language newspapers such as the "Argentinisches Tageblatt" (Argentine Daily).
