Shareholders are required to maintain an investment in Class B stock equal to the sum of a membership investment requirement and an activity-based investment requirement. The membership investment requirement is currently 0.04 percent of each member's total assets as of December 31, 2012, subject to a minimum of $1,000 and a maximum of $7,000,000. The activity-based investment requirement is currently 4.10 percent of outstanding advances.

The Bank generally repurchases surplus stock on the last business day of the month following the end of each calendar quarter. For the repurchases that occurred on January 31, 2013, April 30, 2013, July 31, 2013 and October 31, 2013, surplus stock was defined as the amount of stock held by a member in excess of 102.5 percent of the member’s minimum investment requirement. For the repurchases that occurred on each of these dates, a member's surplus stock was not repurchased if the amount of that member's surplus stock was $100,000 or less or if, subject to certain exceptions, the member was on restricted collateral status. On January 31, 2013, April 30, 2013, July 31, 2013 and October 31, 2013, the Bank repurchased surplus stock totaling $198,427,400, $168,555,900, $182,879,400 and $224,091,800, respectively, none of which was classified as mandatorily redeemable capital stock at those dates.
