( a ) total debt includes scheduled principal payments only .
( b ) represents debt obligations borrowed from non-consolidated variable interest entities for which international paper has , and intends to effect , a legal right to offset these obligations with investments held in the entities .
accordingly , in its con- solidated balance sheet at december 31 , 2012 , international paper has offset approximately $ 5.2 billion of interests in the entities against this $ 5.2 billion of debt obligations held by the entities ( see note 11 variable interest entities and preferred securities of subsidiaries on pages 69 through 72 in item 8 .
financial statements and supplementary data ) .

pension obligations and funding at december 31 , 2012 , the projected benefit obliga- tion for the company 2019s u.s .
defined benefit plans determined under u.s .
gaap was approximately $ 4.1 billion higher than the fair value of plan assets .
approximately $ 3.7 billion of this amount relates to plans that are subject to minimum funding require- ments .
under current irs funding rules , the calcu- lation of minimum funding requirements differs from the calculation of the present value of plan benefits ( the projected benefit obligation ) for accounting purposes .
in december 2008 , the worker , retiree and employer recovery act of 2008 ( wera ) was passed by the u.s .
congress which provided for pension funding relief and technical corrections .
funding contributions depend on the funding method selected by the company , and the timing of its implementation , as well as on actual demo- graphic data and the targeted funding level .
the company continually reassesses the amount and timing of any discretionary contributions and elected to make voluntary contributions totaling $ 44 million and $ 300 million for the years ended december 31 , 2012 and 2011 , respectively .
at this time , we expect that required contributions to its plans in 2013 will be approximately $ 31 million , although the company may elect to make future voluntary contributions .
the timing and amount of future contributions , which could be material , will depend on a number of factors , including the actual earnings and changes in values of plan assets and changes in interest rates .
