How to obtain model information from forecast package

I have a little stupid question about forecast package. I want to get information about model formula. For example:

library(forecast)
fit <- auto.arima(WWWusage)
print(fit)

This produces: 

Series: WWWusage 
ARIMA(1,1,1)                    

Coefficients:
         ar1     ma1
      0.6504  0.5256
s.e.  0.0842  0.0896

sigma^2 estimated as 9.995:  log likelihood=-254.15
AIC=514.3   AICc=514.55   BIC=522.08

So in this case I can see that the model is ARIMA(1,1,1). But I can't find how to extract this directly.
