Calculating efficiency over a period of time can identify opportunities to reorganize staffing, or add or remove employees based on the company's volume of business, and an individual employee's long-term productivity can factor into merit increases and bonuses.
While trusts avoid probate, they don't avoid taxes. A transfer from a revocable trust will be taxed the same way as a transfer made through a will. Someone who inherits money from a revocable trust receives it tax-free, but the estate might have to pay estate tax on everything that it contains before distributing it.
As a beneficiary of an estate, you are not taxable on any assets received (money or property) unless it would have been taxable to the decedent (i.e. an IRA or pension account). Thus, you are not taxable on your inheritance of cash or real estate by the U.S. directly.
