Section 431 (d)(1 )(A) of the Code requires the Secretary to extend the period of time required to amortize any unfunded liability of a plan for a period of time (not in excess of 5 years) if the plan submits an application meeting the criteria stated in section 431 (d)(1 )(B) of the Code. The Plan has submitted the required information to meet the criteria in section 431 (d)(1 )(B) of the Code, including a certification from the plan's actuary that: (i) absent the extension under section 431 (a)(1 )(A) of the Code, the Plan would have an accumulated funding deficiency in the current plan year or any of the 9 succeeding plan years, (ii) the Plan Sponsor has adopted a plan to improve the Plan's funding status, (iii) the Plan is projected to have sufficient assets to timely pay expected benefits and anticipated expenditures over the amortization period as extended, and (iv) the notice required under section 431 (d)(3)(A) has been provided, in accordance with section 3.05 of Rev. Proc. 2010-52. In granting this ruling, it is expected that: (i) the Plan's assumptions and methods will be reviewed and updated as appropriate so that each prescribed assumption is applied in accordance with applicable law and regulations, (ii) each other assumption is reasonable (taking into account the experience of the Plan and reasonable expectations) and such other assumptions, in combination, offer the best estimate of anticipated experience under the Plan, and (iii) the plan sponsor obtained the appropriate approvals for any changes in assumptions or funding methods (whether through an individual private letter ruling or by qualifying for automatic approvals available in the Code, Treasury Regulations or other generally applicable guidance).
