N.C. Gen. Stat. § 58-3-75
In any determination of the financial condition of any fire or marine or fire and marine insurance company authorized to do business in this State, such company shall be charged, in addition to its unearned premium liability as prescribed in G.S. 58-3-71, with a liability for loss reserves in an amount equal to the aggregate of the estimated amounts payable on all outstanding claims reported to it which arose out of any contract of insurance or reinsurance made by it, and in addition thereto an amount fairly estimated as necessary to provide for unreported losses incurred on or prior to the date of such determination, as defined in G.S. 58-3-81(a), and including, both as to reported and unreported claims, an amount estimated as necessary to provide for the expense of adjusting such claims, and there shall be deducted, in determining such liability for loss reserves, the amount of reinsurance recoverable by such company, in respect to such claims, from assuming insurers in accordance with G.S. 58-7-21. Such loss and loss expense reserves shall be calculated in accordance with any method adopted or approved by the NAIC, unless the Commissioner determines that another more conservative method is appropriate.
