accrued (initiated deferred) proportion of income <strong>and</strong> <strong>the</strong> growth in past (forward) income. It can<br />
be seen as an adjustment term for <strong>accruals</strong> that take more than one period to reverse. They are<br />
zero when (a) <strong>the</strong>re is no growth in past <strong>and</strong> future income, or (b) no portion of income is<br />
deferred or prepaid in <strong>the</strong> past <strong>and</strong> <strong>the</strong> future, or (c) when T is equal to one, where T is <strong>the</strong><br />
number of periods it takes <strong>the</strong> <strong>accruals</strong> to reverse.<br />
As in <strong>the</strong> implications from (5), expression (24) indicates that normal <strong>accruals</strong> comprise of<br />
accrued <strong>and</strong> deferred components, with each of <strong>the</strong>m respectively consisting of three parts. The<br />
first part of <strong>the</strong> accrued (deferred) component of normal <strong>accruals</strong> captures <strong>the</strong> interaction<br />
between short-term growth in income <strong>and</strong> proportions of accrued (deferred) component in<br />
current income. If any of <strong>the</strong> two factors is zero, <strong>the</strong>n <strong>the</strong> first part of <strong>the</strong> accrued (deferred)<br />
component of normal <strong>accruals</strong> will be zero. The second part is attributed to <strong>the</strong> relaxation of<br />
credit (payable) policy. With <strong>the</strong> same level of income, firms can end up with higher magnitudes<br />
of accrued (deferred) components of <strong>accruals</strong> if a greater proportion of accrued revenue <strong>and</strong>/or<br />
expenses is recognized. The final part serves as an adjustment term for <strong>accruals</strong> which take more<br />
than one period to reverse.<br />
Finally, <strong>the</strong> above expression can be generalized to different categories of <strong>accruals</strong>. Let AC be a<br />
particular category of <strong>accruals</strong>, <strong>and</strong> EC is <strong>the</strong> income from <strong>the</strong> associated clean-surplus relation<br />
in Table 1. In our previous derivation AC represents TACC <strong>and</strong> EC will represent CNI. Likewise,<br />
if AC represents ∆NOA, <strong>the</strong>n EC will represent OI. One can show that for a given AC,<br />
