We used "AvailableForSaleSecuritiesGrossUnrealizedGainLoss" in prior filings for this concept, but the 2013 taxonomy deprecated the above concept and created a new one with the period type changed to 'duration.' We must have an 'instant' period type in order to complete the calculation within this schedule. This is the unrealized gain on all our available-for-sale investments as of the quarter ending date.
