(in millions)
New rates and rider recovery$19.8
Retail customer growth and demand7.6
Weather(14.5)
Prior year true-up of Winter Storm Uri carrying costs (a)(10.3)
Mark-to-market on non-utility natural gas commodity contracts(3.5)
Other(2.1)
$(3.0)

(a)

In certain jurisdictions, we have commission approval to recover carrying costs on Winter Storm Uri regulatory assets which offset increased interest expense. Additionally, the carrying costs accrued during the year ended December 31, 2022 included a one-time, $10.3 million true-up to reflect commission authorized rates.

Operations and maintenance expense increased primarily due to $14.8 million of higher employee-related expenses partially offset by $5.0 million of lower outside services expenses.

Depreciation and amortization was comparable to the prior year.

Taxes - property and production were comparable to the prior year.
