Operation and maintenance expense increased $27 million in 2014 and increased $44 million in 2013. The increase in 2014 is primarily due to
increased gas operations expenses of $32 million, increased uncollectible expenses of $4 million, and increased corporate administrative expenses of $3
million, partially offset by decreased employee benefit expenses of $10 million and reduced energy optimization expenses of $2 million. The increase in
2013 is primarily due to increased gas operations expenses of $24 million, increased maintenance and repair costs of $14 million, increased transmission
costs of $14 million, increased corporate administrative expenses of $8 million and increased uncollectible expenses of $5 million, partially offset by
decreased employee benefit expenses of $19 million and decreased energy optimization expenses of $3 million.
Other (income) and deductions increased $27 million in 2014 and decreased $19 million in 2013. The increase in 2014 is primarily due to
contributions to the DTE Energy Foundation and other charitable organizations in 2014. The decrease in 2013 is due to lack of a contribution to the DTE
Energy Foundation in 2013, partially offset by a $5 million contribution to low income energy assistance funds.
Outlook — We continue to move forward in our efforts to achieve operational excellence, sustained strong cash flows and earn our authorized return on
equity. We expect that our planned significant infrastructure capital investments will result in earnings growth. Looking forward, additional factors may
impact earnings such as weather, the outcome of regulatory proceedings, benefit plan design changes, and investment returns and changes in discount rate
assumptions in benefit plans and health care costs. We expect to continue our efforts to improve productivity and decrease our costs while improving
customer satisfaction with consideration of customer rate affordability.

Operating revenues increased $71 million in 2014 and increased $36 million in 2013. The increases were due primarily to increased volumes on the
Bluestone pipeline and additional segments placed in service in the Susquehanna gathering system. Storage revenue also increased due to weather
favorability in early 2014, partially offset by lower market rates.
Operation and maintenance expense increased $21 million in 2014 and increased $6 million in 2013. The increases were due primarily to increased
activity on the Bluestone and Susquehanna projects and increased corporate overheads due to growth of this segment.
