Deposit Contracts, Liabilities [Abstract] |
Deposit contracts | Deposit contracts Deposit liability contracts each contain a fixed interest crediting rate, which ranges from 2.5% to 3.0%. Certain deposit contracts also contain a variable interest crediting feature based on actual investment returns realized by the Company that can increase the overall effective interest crediting rate on those contracts to 6.1% to 6.5%. These variable interest crediting features are considered embedded derivatives. We include the estimated fair value of these embedded derivatives with the host deposit liability contracts. Changes in the estimated fair value of these embedded derivatives are recorded in other expenses in the condensed consolidated statements of income. The following table represents activity in the deposit liabilities for the six months ended June 30, 2014 and the year ended December 31, 2013:
