What is the formal charge on the oxygen atom in N_2O?

We gots $2 \times 5 + 6$ $\text{valence electrons}$ to distribute over three centres......
The Lewis structure commonly invoked is $: N \equiv \stackrel{+}{N} - {O}^{-}$. From left to right, there are 7, 6, and 9 electrons associated with nitrogen, nitrogen, and oxygen, which gives rise to formal charges of $0 , + 1 ,$ and $- 1$ respectively.
