STM32L010K8 internal EEPROM's default value

Hello, 

I'm looking for the default EEPROM memory values of STM32L0 family microcontroller. I'm using STM32L010K8 with internal 256 bytes EEPROM. I couldn't find any information about the default EEPROM values. When reading EEPROM values using STM32CubeProgrammer, it shows the values are all 0. Can somebody please confirm that this is the default EEPROM value after the chip is shipped out from the factory? Thank you!
