LIFO or FIFO?
Ricardo “Rick” Martino, president and chief operating officer of Merrimack Tractors and Mowers,
Inc., of Nashua, New Hampshire, felt that his job had grown much more complicated during 2007
and 2008. Merrimack was a major regional manufacturer and seller of large commercial grass mowers
based on a design developed by his grandfather in the years after World War II. The company’s
major competitors were John Deere, The Toro Company, Simplicity, and Husqvarna—much older
and larger corporations with extensive lines of lawn care and maintenance equipment.
Originally, Merrimack mowers were manufactured and assembled in a workshop and factory in
Nashua. However, by 2008 the company was buying all of its tractors and machines, manufactured to
its specifications, from a contract manufacturer in China, and it was operating almost exclusively as a
machine-and-parts designer and distributor. The company had incorporated in 1980, and an initial
public offering was followed by additional offerings of shares over the next decade. By 2008 the
company had about 4,000 shareholders, including some mutual funds. About 25% of the outstanding
stock was held by members of the Martino family, and shares were traded on NASDAQ. Rick had
been elected president after the death of his father late in 1995.
Martino’s father had initiated several changes and made decisions that led to the company’s
current situation. In the early 1980s, management closed down the last manufacturing operations in
Nashua. Labor costs in Japan, and later in China, had historically been well below those in the United
States, so it made sense to outsource manufacturing to Japanese and, later, Chinese manufacturers.
Even with shipping costs, the mowers’ variable cost was substantially less than it would have been in
Nashua. The China arrangements had worked well, and there had been no problems meeting
demand in Merrimack’s markets at competitive prices. Through the years, the Martinos had thought
about expanding beyond their regional base but, in contrast to their competitors who had developed
national and international sales forces, had never done so.
However, by 2008 a number of things had changed. Economic development, including activities
supporting the 2008 Beijing Olympics Games, had increased wages and labor costs in China, and
material and energy costs were also rising. These cost increases were compounded by the ever

strengthening value of the Chinese currency (the Yuan or Renminbi) compared with the U.S. Dollar.1
Loyal suppliers had no choice but to raise prices they charged Merrimack for the mowers they
manufactured. Rising oil prices had also increased the costs of shipping finished mowers to the
United States. The cost of shipping a 40-foot container from Shanghai to the U.S. east coast had risen
from $3,000 in 2000 to almost $9,000 by 2008. These trends were in direct contrast to competitors like
The Toro Company, which still retained a material U.S. manufacturing presence that was less affected
by increasing manufacturing costs in Asia and actually appeared to benefit from the weakening
dollar in the export markets in which it competed. As a result, Merrimack’s sales margins on tractors
and mowers were under pressure. The projected net income for 2008 was below that of 2007 and
earlier years. Outside directors had been pressuring Rick Martino to keep earnings growing or face
the possibility that they would replace him with a professional manager who was not a Martino
family member.
Company management had discussed these trends but dismissed the idea of re-establishing
manufacturing operations in Nashua. Seeking another off-shore supplier was a possibility, but there
was no way of doing so before the end of 2008 or even 2009 if the company’s profit trends and
growth were to be maintained. Only the company controller, James Colburn, had an idea that seemed
worth considering to maintain the trend in income growth at Merrimack. Martino did not fully
understand the idea, which was based on changing the method of accounting for inventories of
tractors, mowers, and parts, but he felt he should carefully consider the idea for the change before
rejecting it. He also was a little uncomfortable with the idea of changing the rules of accounting to
increase reported income. Colburn tried to reassure Rick that Merrimack would have to make
additional disclosures in the notes to its financial statements explaining why it was changing its
method for accounting for inventory, and showing retroactive restatements of income, earnings per
share, inventory and total assets, retained earnings, and shareholders’ equity for the last several
years.
Inventory Accounting at Merrimack Mowers
In the earliest years at Merrimack, the company controller measured income by matching cash
received to the costs required to produce mowers. As a small, unincorporated business run by the
founder of the company, cash flow was considered an adequate measure of income, and income taxes
were paid by family members and employees who received cash from the company. With the
incorporation of the company in 1980, however, new accounting policies needed to be selected and
applied. Since that time, inventories had been reported at cost and using an assumption of last-in,
first-out (LIFO) flows applied on a periodic basis. LIFO had been selected to save on income tax
payments so that the cash saved could be used for investments, and about $2 million had been saved
since 1980.2
James Colburn told Rick Martino that if the company changed inventory accounting to a first-in,
first-out (FIFO) assumption, Merrimack could report a higher income figure in 2008 than it had
reported for 2007 but that this increase was likely to come at the cost of an increase in taxes payable.
Martino was surprised a simple change in accounting could increase company profits, but he
admitted to Colburn that his understanding of inventory accounting was scanty, and he would need
help understanding how a change might work. He was also acutely aware of the Securities and
Exchange Commission’s Financial Reporting Release (“FRR”) 36 which requires that a company’s

1 Since the Chinese authorities had allowed greater flexibility in the exchange rate, the CNY:USD rate of 8.3:1, which had
applied until mid-2005, had fallen to below 7.0:1 by early 2008.
2 Section 472(c) of the U.S. Internal Revenue Code requires that a taxpayer electing to use the LIFO method for tax purposes
must also use the same method for financial reporting.

Management Discussion and Analysis statement filed as part of the annual filings should “give
investors an opportunity to look at the [company] through the eyes of management by providing a
historical and prospective analysis of the [company]’s financial condition and results of operations,
with a particular emphasis on the [company]’s prospects for the future.”
Colburn agreed to prepare an analysis for Martino to illustrate how a change from LIFO to FIFO
inventory accounting might work and why 2008 might be a good year to think about a change to
FIFO. He told Martino that International Financial Reporting Standards (“IFRS”) prohibit the use of
the LIFO method and that moves in American accounting regulations toward the international
standards might require a change away from LIFO in the future anyway, so 2008 might be a good
year to make the change.
Colburn spent the next day preparing a memo for Martino explaining inventory accounting and
two exhibits (based on reel mower units only) showing on a pro-forma basis how income for 2008
might be changed if Merrimack switched from LIFO to FIFO and reported higher income. The memo
and pro-forma income statements are shown in Exhibits 1 and 2.
As soon as Rick Martino received the memo and exhibits, he began to study them, determined to
understand more about how the choice of accounting methods for inventory could have such a
dramatic effect on reported income and could potentially solve the company’s problem.

Exhibit 1 An Explanation of Inventory Accounting Methods
MEMORANDUM
To: Rick Martino, President and COO
From: James Colburn, Controller
Date: July 28, 2008
Subject: Inventory Accounting Methods
Accountants use two different systems of inventory accounting. The first is a “perpetual” system
which keeps track continuously of the value of items of inventory and records a cost-of-goods-sold
expense when each individual item is sold. Obviously, this method can become extremely
cumbersome for companies like ours with many products and high turnover. Like most large
companies, we use a “periodic” inventory system where we do not keep track of day to day
inventory levels but rather calculate an inventory value and cost of goods sold when we take a
physical check of our inventory levels at the end of each fiscal reporting period. The physical count
also allows us to verify if there has been any “shrinkage” of inventory (possibly due to damage,
obsolescence or fraud). Like all other accounts that we use, the following equation applies for
inventory:
Opening Balance on the Account + Increases – Decreases = Ending Balance
In this case, it translates to:
Beginning Inventory + Purchases – Cost of Goods Sold = Ending Inventory
which becomes (with a little algebraic manipulation)
Beginning Inventory + Purchases – Ending Inventory = Cost of Goods Sold
Three assumptions about the flow of costs through inventory accounts are associated with the
most commonly used inventory accounting methods and the inventory valuation method (LIFO,
FIFO and Average Cost). If one assumes that the oldest costs are matched with revenues first, the
method is identified as first-in, first-out, or FIFO, inventory valuation method. Alternatively, if one
assumes that the most recent costs are matched with revenues first, the method is identified as last-in,
first-out, or LIFO. Finally, the average cost method is based on the assumption that an “average cost”
is matched with revenue and provides results somewhere between LIFO and FIFO.
The actual physical flow of items does not need to correspond to the assumed flow of costs and it
seldom does. In accounting for produce in a grocery store, for example, an accountant could use a
LIFO assumption, even though the grocer would probably want to maintain FIFO physical flow.
It is useful to visualize layers of cost built up over time in the inventory account. FIFO always
takes the cost from the oldest layer. LIFO always takes the cost from the most recent layer, with the
result that the oldest layers may be costs measured well in the past.
In the United States, the Internal Revenue (Tax) Code permits companies to use the LIFO
assumption in calculating income subject to taxation provided that it is also used for financial
reporting purposes. If costs and prices are rising, the expensing of more recently purchased, highpriced
inventory increases cost of goods sold, reduces taxable income, and reduces tax payments if
the LIFO assumption is used. This was the case in 1980 when we elected to begin using the LIFO
method.

At the end of 2007, the difference between the LIFO and FIFO valuation of our inventory (which is
equal to the sum of the differences in Cost of Goods Sold between the two accounting methods since
1980) was approximately $5.5 million. As a result, we have not paid about $2 million in taxes which
would have been paid had we elected LIFO back in 1980. The real cost of us switching to FIFO is that
we will need to restate our historic earnings and realize the increase in inventory value of $5.5 million
leading to an instant tax liability of almost $2 million. However, there is probably an ongoing
increase in taxes payable as well.
This is not really an “additional” tax but just relates to the timing of the payment. The use of LIFO
means that the IRS has given us a delay in payment compared to the use of FIFO since 1980. If the
company was ever liquidated, we would reduce our inventory to zero and then there would be no
difference between the LIFO and FIFO inventory valuations. In such a setting, the cumulative
differences in Cost of Goods Sold over the life of the company would also go to zero and so we
would end up having to pay the amount anyway.
