I have American Depositary Receipts (ADRs) for the underlying Russian stocks. These ADRs are not trading in US for a year while the underlying stock trades in Russia ok. US financial institutions (Citi, BONY, etc) that sponsored there ADRs exited depositary agreements in mid ' 22 and, effectively, abandoned underlying securities. Thus, there is no link between these phantom ADRs and underlying Russian shares. Can I consider these ADRs worthless for tax purposes and write them off for '22? Brokerage statement shows some of them with N/A in the value column.
