funding practices , we currently believe that we will not be required to make any contributions under the new ppa requirements until after 2012 .
accordingly , we do not expect to have significant statutory or contractual funding requirements for our major retiree benefit plans during the next several years , with total 2007 u.s .
and foreign plan contributions currently estimated at approximately $ 54 million .
actual 2007 contributions could exceed our current projections , as influenced by our decision to undertake discretionary funding of our benefit trusts versus other competing investment priorities , future changes in government requirements , renewals of union contracts , or higher-than-expected health care claims experience .
additionally , our projections concerning timing of ppa funding requirements are subject to change primarily based on general market conditions affecting trust asset performance and our future decisions regarding certain elective provisions of the ppa .
in comparison to 2005 , the unfavorable movement in core working capital during 2006 was related to trade payables performance and higher inventory balances .
at december 30 , 2006 , our consolidated trade payables balance was within 3% ( 3 % ) of the balance at year-end 2005 .
in contrast , our trade payables balance increased approximately 22% ( 22 % ) during 2005 , from a historically-low level at the end of 2004 .
the higher inventory balance was principally related to higher commodity prices for our raw material and packaging inventories and to a lesser extent , the overall increase in the average number of weeks of inventory on hand .
our consolidated inventory balances were unfavorably affected by u.s .
capacity limitations during 2006 ; nevertheless , our consolidated inventory balances remain at industry-leading levels .
despite the unfavorable movement in the absolute balance , average core working capital continues to improve as a percentage of net sales .
for the trailing fifty-two weeks ended december 30 , 2006 , core working capital was 6.8% ( 6.8 % ) of net sales , as compared to 7.0% ( 7.0 % ) as of year-end 2005 and 7.3% ( 7.3 % ) as of year-end 2004 .
we have achieved this multi-year reduction primarily through faster collection of accounts receivable and extension of terms on trade payables .
up until 2006 , we had also been successful in implementing logistics improvements to reduce inventory on hand while continuing to meet customer requirements .
we believe the opportunity to reduce inventory from year-end 2006 levels could represent a source of operating cash flow during 2007 .
for 2005 , the net favorable movement in core working capital was related to the aforementioned increase in trade payables , partially offset by an unfavorable movement in trade receivables , which returned to historical levels ( in relation to sales ) in early 2005 from lower levels at the end of 2004 .
we believe these lower levels were related to the timing of our 53rd week over the 2004 holiday period , which impacted the core working capital component of our operating cash flow throughout 2005 .
as presented in the table on page 16 , other working capital was a source of cash in 2006 versus a use of cash in 2005 .
the year-over-year favorable variance of approximately $ 116 million was attributable to several factors including lower debt-related currency swap payments in 2006 as well as business-related growth in accrued compensation and promotional liabilities .
the unfavorable movement in other working capital for 2004 , as compared to succeeding years , primarily relates to a decrease in current income tax liabilities which is offset in the deferred income taxes line our management measure of cash flow is defined as net cash provided by operating activities reduced by expenditures for property additions .
we use this non-gaap financial measure of cash flow to focus management and investors on the amount of cash available for debt repayment , dividend distributions , acquisition opportunities , and share repurchase .
our cash flow metric is reconciled to the most comparable gaap measure , as follows: .

year-over-year change 24.5% ( 24.5 % ) fffd19.1% ( fffd19.1 % ) our 2006 and 2005 cash flow ( as defined ) performance reflects increased spending for selected capacity expansions to accommodate our company 2019s strong sales growth over the past several years .
this increased capital spending represented 4.2% ( 4.2 % ) of net sales in 2006 and 3.7% ( 3.7 % ) of net sales in 2005 , as compared to 2.9% ( 2.9 % ) in 2004 .
for 2007 , we currently expect property expenditures to remain at approximately 4% ( 4 % ) of net sales , which is consistent with our long-term target for capital spending .
this forecast includes expenditures associated with the construction of a new manufacturing facility in ontario , canada , which represents approximately 15% ( 15 % ) of our 2007 capital plan .
this facility is being constructed to satisfy existing capacity needs in our north america business , which we believe will partially ease certain of the aforementioned logistics and inventory management issues which we encountered during 2006 .
for 2007 , we are targeting cash flow of $ 950-$ 1025 million .
we expect to achieve our target principally through operating .
