The Mt. Gox Trustee Balance corresponds to the amount of BTC held in addresses controlled by Nobuaki Kobayashi, the trustee overseeing the Mt. Gox civil rehabilitation proceedings.

This is the Point-in-Time (PiT) variant of Mt. Gox Balance. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
