DSRI=(Receivables_t / Revenue_t) / (Receivables_t-1 / Revenue_t-1)
=(442.091 / 1569.787) / (314.502 / 1378.232)

SGI=Sales_t / Sales_t-1
=Revenue_t / Revenue_t-1
=1569.787 / 1378.232

5. DEPI = Depreciation Index

Measured as the ratio of the rate of Depreciation, Depletion and Amortization in year t-1 to the corresponding rate in year t.

DEPI greater than 1 indicates that assets are being depreciated at a slower rate. This suggests that the firm might be revising useful asset life assumptions upwards, or adopting a new method that is income friendly.

DEPI=(Depreciation_t-1 / (Depreciaton_t-1 + PPE_t-1)) / (Depreciation_t / (Depreciaton_t + PPE_t))
=(28.745 / (28.745 + 142.218)) / (24.837 / (24.837 + 136.187))
=0.168136 / 0.154244
=1.0901

Note: If the Depreciation, Depletion and Amortization data is not available, we assume that the depreciation rate is constant and set the Depreciation Index to 1.

The ratio of Selling, General, & Admin. Expense(SGA) to Sales in year t relative to year t-1.

SGA expenses index > 1 means that the company is becoming less efficient in generate sales.

SGAI=(SGA_t / Sales_t) / (SGA_t-1 /Sales_t-1)
=(297.865 / 1569.787) / (300.861 / 1378.232)
=0.189749 / 0.218295

=((1.051 + 934.665) / 2026.977) / ((12.009 + 959.262) / 2024.275)
=0.461631 / 0.479812
=0.9621
