B notifies C, an aircraft manufacturer, that it wants to purchase an aircraft of a particular type. At the time C receives the order, C has on hand several partially completed aircraft of this type; however, C does not have any completed aircraft of this type on hand. C and B agree that B will purchase one of these aircraft after it has been completed. C retains title to and risk of loss with respect to the aircraft until the sale takes place. The agreement between C and B is a contract for the manufacture of property under paragraph (b)(2)(i) of this section, even if labeled as a contract for the sale of property, because the manufacture of the aircraft is necessary for C's obligations under the agreement to be fulfilled and the manufacturing was not complete when B and C entered into the agreement.
C, a master developer whose taxable year ends December 31, owns 5,000 acres of undeveloped land with a cost basis of $5,000,000 and a fair market value of $50,000,000. To obtain permission from the local county government to improve this land, a service road must be constructed on this land to benefit all 5,000 acres. In 2001, C enters into a contract to sell a 1,000-acre parcel of undeveloped land to B, a residential developer, for its fair market value, $10,000,000. In this contract, C agrees to construct a service road running through the land that C is selling to B and through the 4,000 adjacent acres of undeveloped land that C has sold or will sell to other residential developers for its fair market value, $40,000,000. C reasonably estimates that it will incur allocable contract costs of $50,000 (excluding the cost of the land) to construct this service road, which will be owned and maintained by the county. C must reasonably allocate the cost of the service road among the benefitted parcels. The portion of the estimated total allocable contract costs that C allocates to the 1,000-acre parcel being sold to B (based upon its fair market value) is $10,000 ($50,000 × ($10,000,000 ÷ $50,000,000)). Construction of the service road is finished in 2002. Because the estimated total allocable contract costs attributable to C's construction activities, $10,000, are less than 10 percent of the contract's total contract price, $10,000,000, C's contract with B is not a construction contract under paragraph (b)(2)(ii) of this section. Thus, C's contract with B is not a long-term contract under paragraph (b)(2)(i) of this section, notwithstanding that construction of the service road is not completed in 2001.
In 2002, C, whose taxable year ends December 31, enters into a contract to construct a building for B. In November of 2003, the building is completed in every respect necessary for its intended use, and B occupies the building. In early December of 2003, B notifies C of some minor deficiencies that need to be corrected, and C agrees to correct them in January 2004. C reasonably estimates that the cost of correcting these deficiencies will be less than five percent of the total allocable contract costs. C's contract is complete under paragraph (c)(3)(i)(A) of this section in 2003 because in that year, B used the building and C had incurred at least 95 percent of the total allocable contract costs attributable to the building. C must use a permissible method of accounting for any deficiency-related costs incurred after 2003.
In 2001, C, whose taxable year ends December 31, agrees to construct a shopping center, which includes an adjoining parking lot, for B. By October 2002, C has finished constructing the retail portion of the shopping center. By December 2002, C has graded the entire parking lot, but has paved only one-fourth of it because inclement weather conditions prevented C from laying asphalt on the remaining three-fourths. In December 2002, B opens the retail portion of the shopping center and the paved portion of the parking lot to the general public. C reasonably estimates that the cost of paving the remaining three-fourths of the parking lot when weather permits will exceed five percent of C's total allocable contract costs. Even though B is using the subject matter of the contract, C's contract is not completed in December 2002 under paragraph (c)(3)(i)(A) of this section because C has not incurred at least 95 percent of the total allocable contract costs attributable to the subject matter.
In 2001, C, whose taxable year ends December 31, agrees to manufacture 100 machines for B. By December 31, 2002, C has delivered 99 of the machines to B. C reasonably estimates that the cost of finishing the related work on the contract will be less than five percent of the total allocable contract costs. C's contract is not complete under paragraph (c)(3)(i)(A) of this section in 2002 because in that year, B is not using the subject matter of the contract (all 100 machines) for its intended purpose.
On January 1, 2001, C, whose taxable year ends December 31, enters into a single long-term contract to design and manufacture a satellite and to develop computer software enabling B to operate the satellite. At the end of 2001, C has not finished manufacturing the satellite. Designing the satellite and developing the computer software are non-long-term contract activities that are incident to and necessary for the taxpayer's manufacturing of the subject matter of a long-term contract because the satellite could not be manufactured without the design and would not operate without the software. Thus, under paragraph (d)(1) of this section, C must allocate these non-long-term contract activities to the long-term contract and account for the gross receipts and costs attributable to designing the satellite and developing computer software using the PCM.
C agrees to manufacture equipment for B under a long-term contract. In a separate contract, C agrees to design the equipment being manufactured for B under the long-term contract. Under paragraph (d)(1) of this section, C must allocate the gross receipts and costs related to the design to the long-term contract because designing the equipment is a non-long-term contract activity that is incident to and necessary for the manufacture of the subject matter of the long-term contract.
On January 1, 2001, C, a construction contractor, and B, a real estate investor, enter into an agreement requiring C to build two office buildings in different areas of a large city. The agreement provides that the two office buildings will be completed by C and accepted by B in 2002 and 2003, respectively, and that C will be paid $1,000,000 and $1,500,000 for the two office buildings, respectively. The agreement will provide C with a reasonable profit from the construction of each building. Unless C is required to use the PCM to account for the contract, C is required to sever this contract under paragraph (e)(2) of this section because the buildings are independently priced, the agreement provides for separate delivery and acceptance of the buildings, and, as each building will generate a reasonable profit, a reasonable businessperson would have entered into separate agreements for the terms agreed upon for each building.
C, a large construction contractor whose taxable year ends December 31, accounts for its construction contracts using the PCM and has elected to use the 10-percent method described in § 1.460-4(b)(6). In September 2001, C enters into an agreement to construct four buildings in four different cities. The buildings are independently priced and the contract provides a reasonable profit for each of the buildings. In addition, the agreement requires C to complete one building per year in 2002, 2003, 2004, and 2005. As of December 31, 2001, C has incurred 25 percent of the estimated total allocable contract costs attributable to one of the buildings, but only five percent of the estimated total allocable contract costs attributable to all four buildings included in the agreement. C does not request the Commissioner's consent to sever this contract. Using the 10-percent method, C does not take into account any portion of the total contract price or any incurred allocable contract costs attributable to this agreement in 2001. Upon examination of C's 2001 tax return, the Commissioner determines that C entered into one agreement for four buildings rather than four separate agreements each for one building solely to take advantage of the deferral obtained under the 10-percent method. Consequently, to clearly reflect the taxpayer's income, the Commissioner may require C to sever the agreement into four separate contracts under paragraph (e)(2) of this section because the buildings are independently priced, the agreement provides for separate delivery and acceptance of the buildings, and a reasonable businessperson would have entered into separate agreements for these buildings.
In 2001, C, a shipbuilder, enters into two agreements with the Department of the Navy as the result of a single negotiation. Each agreement obligates C to manufacture a submarine. Because the submarines are of the same class, their specifications are similar. Because C has never manufactured submarines of this class, however, C anticipates that it will incur substantially higher costs to manufacture the first submarine, to be delivered in 2007, than to manufacture the second submarine, to be delivered in 2010. If the agreements are treated as separate contracts, the first contract probably will produce a substantial loss, while the second contract probably will produce substantial profit. Based upon these facts, aggregation is required under paragraph (e)(2) of this section because the submarines are interdependently priced and a reasonable businessperson would not have entered the first agreement without also entering into the second.
In 2001, C, a manufacturer of aircraft and related equipment, agrees to manufacture 10 military aircraft for foreign government B and to deliver the aircraft by the end of 2003. When entering into the agreement, C anticipates that it might receive production orders from B over the next 20 years for as many as 300 more of these aircraft. The negotiated contract price reflects C's and B's consideration of the expected total cost of manufacturing the 10 aircraft, the risks and opportunities associated with the agreement, and the additional factors the parties considered relevant. The negotiated price provides a profit on the sale of the 10 aircraft even if C does not receive any additional production orders from B. It is unlikely, however, that C actually would have wanted to manufacture the 10 aircraft but for the expectation that it would receive additional production orders from B. In 2003, B accepts delivery of the 10 aircraft. At that time, B orders an additional 20 aircraft of the same type for delivery in 2007. When negotiating the price for the additional 20 aircraft, C and B consider the fact that the expected unit cost for this production run of 20 aircraft will be lower than the unit cost of the 10 aircraft completed and accepted in 2003, but substantially higher than the expected unit cost of future production runs. Based upon these facts, aggregation is not permitted under paragraph (e)(2) of this section. Because the parties negotiated the prices of both agreements considering only the expected production costs and risks for each agreement standing alone, the terms and conditions agreed upon for the first agreement are independent of the terms and conditions agreed upon for the second agreement. The fact that the agreement to manufacture 10 aircraft provides a profit for C indicates that a reasonable businessperson would have entered into that agreement without entering into the agreement to manufacture the additional 20 aircraft.
In 2001, C, whose taxable year ends December 31, agrees to manufacture and install an industrial machine for B. C elects under paragraph (f) of this section to classify the agreement as a long-term manufacturing contract and to account for it using the PCM. The agreement requires C to deliver the machine in August 2003 and to install and test the machine in B's factory. In addition, the agreement requires B to accept the machine when the tests prove that the machine's performance will satisfy the environmental standards set by the Environmental Protection Agency (EPA), even if B has not obtained the required operating permit. Because of technical difficulties, C cannot deliver the machine until December 2003, when B conditionally accepts delivery. C installs the machine in December 2003 and then tests it through February 2004. B accepts the machine in February 2004, but does not obtain the operating permit from the EPA until January 2005. Under paragraph (c)(3)(i)(B) of this section, C's contract is finally completed and accepted in February 2004, even though B does not obtain the operating permit until January 2005, because C completed all its obligations under the contract and B accepted the machine in February 2004.
