Do we need the NA values in Budget in Brief?

[MikeTheCanuck]

In PR#20 the "NA" values in the Amount field of the KPM data were dropped.

Question for the City Budget Office: are "NA" KPM values meaningfully distinct from a blank KPM value?

If the City Budget Office deems it equivalent in the representation we develop in the future, it's fine to leave that data out of the KPM endpoint data. If they deem it a meaningful distinction, we will need to find a way to represent that data somehow to those consuming the KPM endpoint.
