 if FIFO had been used in the year 2016.
B. The profit sharing of expense reflects the indirect effect of the change in an accounting principle. Under the SFAS No. 154, the indirect effects from period before the change are recorded in the year of the change.
In this case, profit sharing expense recorded in the year 2007 is composed of :
$ 900 x 10%     =   $ 90 (year 2017 under the FIFO)
$ 60 x 10%   = $ 6 (difference in the profit sharing for the year 2016)
        Net        = $ 96 (profit sharing expense for the FIFO in year 2017)
C.                              Retaining earnings statement of 2017
    Retained earning, Jan 1 as reported                                 $ 8000
