Paragraphs:
ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts)
We account for uncertain tax positions by applying a minimum recognition threshold to tax positions before recognizing these positions in the financial statements. The reconciliation of our total gross unrecognized tax benefits is as follows:
The unrecognized tax benefits of $13.0 million, if recognized, will impact the Company’s effective tax rate. In accordance with our accounting policy, we recognize accrued interest and penalties related to unrecognized tax benefits as a component of tax expense. We had $3.0 million and $1.2 million of accrued interest and penalties at December 31, 2019 and 2018, respectively. We expect the total amount of tax contingencies will decrease by approximately $3.5 million in 2020 based on statute of limitation expiration.
With few exceptions, the Company is no longer subject to federal, state or foreign income tax examinations by tax authorities for years before 2016.
Question:
What was the company's accrued interest and penalties in 2019?
Answer: $3.0 million
