Neutr: Case alignment is neutral: the functions S, A, and P are not marked morphologically.
NoAMark: The function A is not explicitly marked, while S, P, or both are marked. A is therefore marked with a zero (∅) morpheme.
AAff: The function A is marked with affixation.

In Surgut Khanty, the A is in the nominative case in the active voice, which means that it takes a zero morpheme no matter whether it is expressed by a noun or a pronoun. In the case of nominal P’s, which are also unmarked, the S, A, and P roles are neutrally coded (1). However, if the P is expressed by a personal pronoun, it takes the accusative case, hence the A, S and P roles are morphologically distinguishable (cf. NoAMark value) (2). The passive is very frequent in Surgut Khanty, and in this construction the A is marked by the locative (3). The S is always in the nominative (4).
