Example. A, a taxpayer who elected for his taxable year 1952 to include in gross income amounts received as loans from the Commodity Credit Corporation, received as loans $500 in 1952, $700 in 1953, and $900 in 1954. In 1956 all the pledged commodity was sold by the Commodity Credit Corporation for an amount $100 and $200 less than the loans with respect to the commodity pledged in 1952 and 1953, respectively, and for an amount $150 greater than the loan with respect to the commodity pledged in 1954. A, in making his return for 1956, shall include in gross income the sum of $150 if it is received during that year, but will not be allowed a deduction for the deficiencies of $100 and $200 unless he is required to satisfy such deficiencies and does satisfy them during that year.
