DEPI=(Depreciation_t-1 / (Depreciaton_t-1 + PPE_t-1)) / (Depreciation_t / (Depreciaton_t + PPE_t))
=(257.721 / (257.721 + 2619.726)) / (253.422 / (253.422 + 2499.182))
=0.089566 / 0.092066
=0.9728

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.

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)
=(174.922 / 1617.337) / (177.712 / 1808.46)
=0.108154 / 0.098267
=1.1006

An LVGI > 1 indicates an increase in leverage

LVGI=((LTD_t + CurrentLiabilities_t) / TotalAssets_t) / ((LTD_t-1 + CurrentLiabilities_t-1) / TotalAssets_t-1)
=((1666.541 + 2064.043) / 5541.969) / ((1315.908 + 2652.794) / 5899.404)
