Co-xTVaR has almost the opposite advantages and disadvantages of standard deviation. It is calculated as the amount by which each risk is worse than its expectation in those situations in which the totality of risks being modeled exceeds its expectation.

The exercise becomes one of managing tradeoffs, as risk managers balance the simplicity of effort against the potential benefits of capital optimization.

In choosing a capital allocation method, firms must balance the sophistication of the method with calculation time and resource commitment.
