 Other parameters and mechanisms that are dependent on the DSR, such as crypto-collateralized stability fees, are affected by the EDSR. This applies to all crypto-collateralized Vault Types except for Spark Protocol.
 
 Spark Protocol has a borrow rate spread that follows the Exposure Model methodology (14.3.1.3) and is defined as: 
-Spark DAI Effective borrow APY = Dai Savings Rate (EDSR while active) + Liquidation Ratio Spread + Asset Spread.
+Spark DAI Effective Borrow APY = Dai Savings Rate (EDSR while active) + Liquidation Ratio Spread + Asset Spread.
