    (a) Facts. The books of the taxpayer, whose return is made on the 
basis of the calendar year, reveal the following facts:

The taxable income thus shown is computed without any net operating loss 
deduction. The assumption is also made that none of the other 
modifications prescribed in Sec. 1.172-5 apply. There are no net 
operating losses for 1950, 1951, 1952, 1953, 1964, 1965, or 1966.
    (b) Loss sustained in 1956. The portions of the $75,000 net 
operating loss for 1956 which shall be used as carrybacks to 1954 and 
1955 and as carryovers to 1957, 1958, 1959, 1960, and 1961 are computed 
as follows:
    (1) Carryback to 1954. The carryback to this year is $75,000, that 
is, the amount of the net operating loss.
    (2) Carryback to 1955. The carryback to this year is $60,000, 
computed as follows:

Net operating loss...........................................    $75,000
