Times-Roman Publishing Company reports the following amounts in its first three years of operation:

($ in 000s) 2013 2014 2015
Pretax accounting income $ 250 $ 240 $ 230
Taxable income 290 220 260

The difference between pretax accounting income and taxable income is due to subscription revenue for one-year magazine subscriptions being reported for tax purposes in the year received, but reported in the income statement in later years when earned. The income tax rate is 40% each year. Times-Roman anticipates profitable operations in the future.
