  @param grossBillableRevenue   * The gross billable revenue. If this reconciliation data is
  for a {@link ProposalLineItem}
  and the {@link #pricingModel} is {@link PricingModel#GROSS},
  this is calculated from the
  {@link #grossRate}, {@link #billableVolume}, and the
  proposal line item's billing settings.
  This may be {@code null} for certain billing settings.
  Otherwise, the value of this field will
  be the same as the {@link #netBillableRevenue}.
  This value is read-only.
