How do I find out if personal injury award held in a trust account was in an interest bearing account or not?

My personal injury case had two parts, one with the women who hit me and one with my own insurance company. The women who hit me insurance company settled right away and the money was being held in trust until the case against my own insurance company was settled. Now that the case is settled, I received a settlement statement and was surprised to see that no interest earned was included on the statement. My attorneys tell me the trust account earned no interest. How do I know if this is true or not? Thank you.
