Schematic representation of conditions (6) for a single loan <i>j</i>.

<p>The principal amount <i>m</i>_<i>j</i> and each installment are multiplied by their accumulation factor after <i>t</i> periods. If the installment amounts (yellow, red, and green, respectively) are equal to the principal with its accumulation factor (blue) as it happens at time <i>t</i> = 3, then loan <i>j</i> has been completely repaid.</p
