Environmental Perpetuity Cost and Earning Yields of Oil and Gas Marketing Firms: Nigeria’s experience

The study examined the environmental perpetuity cost and earning yields of oil and gas marketing firms: Nigeria’s experience. Its main objective was: to specifically examine the extent to which environmental perpetuity costs influence earning yields of oil and gas marketing firms taking evidence from Nigeria. To achieve the objective, an ex-post facto design was employed and relevant data were obtained from secondary source. Multiple regression analytical tool was used to analyse the data in order to verify the hypotheses formulated for the study. The findings indicated that donations as a perpetuity cost positively influences earning yield though the influence is not a very strong one; support/social cost to destitute and less privileged significantly affect earnings per share; support to motherless babies’ homes and others significantly affect earnings per share; and donations/ social cost to nongovernmental organization significantly affect earnings per share. The researchers then recommended that government should encourage listed firms to disclose their donations which will strengthen the earning per share of these firms via increased employee productivity.
