Shader vertex position

Hi,

I can't figure out what's this. Vertex position relative to object position ? World position ? Camera position ? Something else ?

 o.vertex = mul(UNITY_MATRIX_P,
                 mul(UNITY_MATRIX_MV, float4(0.0, 0.0, 0.0, 1.0))
                 + v.vertex 
                 * float4(_Scale, _Scale, 1.0, 1.0));
