DTE's letter of credit and revolving credit facilities mature from 2019-2022 and include $1.4 billion at DTE, $400 million at DTEE and $300 million at DTE Gas.
DTEE's rating reflects Fitch's expectations of stable earnings and cash flows from the regulated utility operations, a constructive regulatory environment in Michigan and solid credit metrics.

Michigan 2017 Electric Rate Case: On April 18, 2018, DTEE received a rate increase of $65 million based on an above average 10% authorized ROE and a 36.84% regulatory capital structure.
Fitch assumes future equity support from the parent will maintain DTEE's balanced capital structure.

Future delays to completion of the NEXUS pipeline or other unanticipated adverse events could lead to future credit rating downgrades at DTE and DTEE.
DTE's ratings and Negative Rating Outlook reflect the strong credit quality of its two regulated utility subsidiaries, DTEE and DTEG, which are supported by a constructive regulatory environment in Michigan.
