Narrative:
Approximately 150 miles from [the destination airport]; at or near [the top of descent]; EICAS indicated lowering oil quantity on the left engine; but no EICAS caution or warning. Monitored. Quantity dropped to zero. Contacted dispatch and maintenance control referencing the impending shutdown. Oil pressure then slowly decreased. We declared an emergency with ATC. Determined that [the destination airport] to be more suitable than [another diversion airport] due to the 3-to-1 glide profile to [the destination airport]; while [the diversion airport] would require circling to descend with possible weather avoidance in the area. We obtained priority handling direct to [the destination airport]. EICAS then displayed low oil press caution. Shut down engine per ecl checklist. Briefed lead flight attendant. Uneventful landing at [the destination airport].
