We finance our investment portfolio primarily through repurchase agreements (“repo”). Our repurchase transactions generally have maturities that range from 30 days to one year but may have longer or shorter maturities based upon our business needs and risk management strategy. We typically seek to diversify our borrowings across a wide range of counterparties and financing terms.

As of December 31, 2018, we had 46 repo counterparties and a weighted average agency funding rate of 2.79%. Our weighted average days to maturity for agency financing transactions totaled 49 days as of December 31, 2018.
