Contingent Corporation has the following contingencies on its horizon: $30,000 20,000 30,000 ?

(a) A lawsuit by Corporation Z, for which it is probable that Contingent will have to pay $20,000

(b) A reasonable possibility that Contingent will win a tax court case, resulting in a tax refund of $19,000

(c) A remote chance of hurricane damage to its building, resulting in a $17,000 loss

(d) A reasonably possible chance that Contingent will win a $10,000 lottery. (Contingent's chief executive officer may be able to "rig" the drawing!)

Determine the correct accounting treatment for each of the above.
