During 2018, Becky loans her brother Ken $5,000, which he in-tends to use to establish a small business. Because Ken has no other assets and needs cash to establish the business, the agreement provides that Ken will repay the debt if (and when) sufficient funds are generated from the business. Becky and Ken do not establish an interest rate. The business is unsuccessful, and Ken is forced to file for bankruptcy in 2019. By the end of 2019, it is estimated that the creditors will receive only 20% of the amount owed. In 2020 the bankruptcy proceedings are closed, and the creditors receive 10% of the amount due on the debt. What is Becky's bad debt deduction for 2019? For 2020?
