Pool APY
Annual Percentage Yield of the underlying pool.
In the case of lending, the spread is the difference between the lending APY (the % of compounded interests paid to lenders) and the borrowing APY (the % of compounded interests paid by borrowers).
Utilization rate
Percentage of funds supplied that is actually borrowed and thus generating interests. When fully matched P2P, the utilization rate is, by definition, 100%. When on the pool, the utilization rate of the sum of all funds is below 100% as there is always more liquidity available than borrowed.
