EBU Single Rulebook Q&A 8 January 2014 2014_716 Handling of unrealised gains/losses in Own Funds and Exposures

Does unrealised gains/losses refer to all gains and losses for financial instruments accounted at fair value which occured life to date or only unrealised gains/losses of the current year? Will unrealised gaines and losses despite being deducted from own funds be still part of the exposure? How should the position "Losses for the current financial year" be calculated?
