Internal oscillator tolerance after production

In the manual I found the following sentence: "The internal oscillator circuit is designed for use with no external components to provide a clock source with tolerance less than ±25% untrimmed. An 8-bit trimming register allows adjustment to a tolerance of less than ±5%.
 
Now my question:
Is the tolerance after production 25% or 5%, what means is the controller after production trimmed or untrimmed?
