How does surprise library handle missing values in matrix factorisation SVD model?

I am not sure how it handles missing values. Does it fill NA values with 0 and then do the matrix factorization or it simply does not consider those missing values while calculating cost function.

I tried lookin for it in the documentation but it is not mentioned anywhere.
