Other Income (Expense), Net Items recorded to other income (expense), net arise from transactions and events not directly related to our principal income earning activities.
The detail of other income (expense), net is presented in Note 24, Supplemental Information, to the consolidated financial statements.2016 vs.  2015 Other income (expense), net of $58.1 increased $10.8 primarily due to lower foreign exchange losses, favorable contract settlements, and receipt of a government subsidy.
The prior year included a gain of $33.6 ($28.3 after-tax, or $.13 per share) resulting from the sale of two parcels of land.
No other individual items were significant in comparison to the prior year.2015 vs.  2014 Other income (expense), net of $47.3 decreased $5.5 and included a gain of $33.6 ($28.3 after-tax, or $.13 per share) resulting from the sale of two parcels of land.
The gain was partially offset by unfavorable foreign exchange impacts and lower gains on other sales of assets and emissions credits.
No other individual items were significant in comparison to fiscal year 2014.
## Table 0 ##
2016 vs.  2015 Interest incurred decreased $4.2.
The decrease primarily resulted from a stronger U. S.  dollar on the translation of foreign currency interest of $6, partially offset by a higher average debt balance of $2.
The change in capitalized interest was driven by a decrease in the carrying value of projects under construction, primarily as a result of our exit from the Energy-from-Waste business.2015 vs.  2014 Interest incurred decreased $5.5.
The decrease was driven by the impact of a stronger U. S.  dollar on the translation of foreign currency interest of $12, partially offset by a higher average debt balance of $7.
The change in capitalized interest was driven by a higher carrying value in construction in progress.
Loss on Extinguishment of Debt On 30 September 2016, in anticipation of the Versum spin-off, Versum issued $425.0 of notes to Air Products, who then exchanged these notes with certain financial institutions for $418.3 of Air Products’ outstanding commercial paper.
The exchange resulted in a loss of $6.9 ($4.3 after-tax, or $.02 per share).
In September 2015, we made a payment of $146.6 to redeem 3,000,000 Unidades de Fomento (“UF”) Series E 6.30% Bonds due 22 January 2030 that had a carrying value of $130.0 and resulted in a net loss of $16.6 ($14.2 after-tax, or $.07 per share).
Effective Tax Rate The effective tax rate equals the income tax provision divided by income from continuing operations before taxes.
Refer to Note 23, Income Taxes, to the consolidated financial statements for details on factors affecting the effective tax rate.2016 vs.  2015 On a GAAP basis, the effective tax rate was 27.5% and 24.0% in 2016 and 2015, respectively.
The change included a 240 bp impact from tax costs associated with business separation, primarily resulting from a dividend declared in 2016 to repatriate cash from a foreign subsidiary, as discussed above in “Business Separation Costs.
” The remaining 110 bp change was primarily due to the increase in mix of income in jurisdictions with a higher effective tax rate and the impact of business separation costs for which a tax benefit was not available.
On a nonGAAP basis, the effective tax rate increased from 24.2% in 2015 to 24.8% in 2016, primarily due to the increase in and mix of income in jurisdictions with a higher effective tax rate.
Homebuilding Operating Margin Analysis
## Table 1 ##
Home Sales Gross Profit Gross profit from home sales increased by 59%, to $744.0 million in 2010, from $467.5 million in 2009, and, as a percentage of home sales revenues, increased 420 basis points, to 17.3%.
Approximately 350 basis points of the increase in the home sales gross profit percentage was a result of the average cost of our homes declining by more than our average selling prices, caused largely by a reduction in our construction costs on homes closed during the current year.
The reduction in construction costs primarily results from changes in product design, as well as cost reductions obtained from our suppliers and sub-contractors in prior periods.
In addition, the increase in home sales gross profit is partially due to our efforts beginning in fiscal 2009 to acquire lot positions in new communities and construct and close houses from these new projects.
Homes closed on these recently acquired finished lots yielded higher gross profits than those on land and lots acquired in prior years.
Approximately 70 basis points of the increase was due to a decrease in the amortization of capitalized interest and property taxes as a percentage of homes sales revenues, resulting from reductions in our interest and property taxes incurred over the past year, as well as more closings occurring on acquired finished lots, rather than internally developed lots.
Future changes in gross profit percentages are impacted by the use of sales incentives and price adjustments to generate an adequate volume of home closings.
We expect our gross profit percentage to decline in the first half of fiscal 2011 due to current weak housing market conditions.
Land Sales Revenue Land sales revenues decreased 82% to $7.4 million in 2010, from $40.3 million in 2009.
Of the $40.3 million of revenues in fiscal 2009, $26.9 million related to land sale transactions in the fourth quarter of fiscal 2008 for which recognition of the revenue had been deferred due to the terms of the sale.
Fluctuations in revenues from land sales are a function of how we manage our inventory levels in various markets.
We generally purchase land and lots with the intent to build and sell homes on them; however, we occasionally purchase land that includes commercially zoned parcels which we typically sell to commercial developers, and we also sell residential lots or land parcels to manage our land and lot supply.
Land and lot sales occur at unpredictable intervals and varying degrees of profitability.
Therefore, the revenues and gross profit from land sales fluctuate from period to period.
As of September 30, 2010, we had $3.3 million of land held for sale that we expect to sell in the next twelve months.
Net Sales Orders The value of net sales orders increased 27%, to $8,308.6 million (29,709 homes) in 2014 from $6,567.0 million (25,120 homes) in 2013, with significant increases in four of our six regions.
The increases in sales order value in those regions were primarily due to increases in volume as we have expanded our operations and increased our market share in many of our markets over the past year.
To a lesser extent and to varying degrees, increases in selling prices also contributed to the value of net sales orders in each region.
The number of net sales orders increased 18% and the average price of our net sales orders increased 7% to $279,700 during 2014 compared to 2013.
The largest percentage increase in net sales orders occurred in our East region, reflecting the positive impact of our recent acquisitions of the homebuilding operations of Regent Homes and Crown Communities, which contributed 714 net sales orders to the East region in 2014.
Crown Communities also contributed 508 net sales orders to the Southeast region in 2014.
The decreases in net sales orders that occurred in our Midwest and Southwest regions were primarily due to decreases in sales orders in our Minnesota, Colorado, Phoenix and Albuquerque markets.
We believe our business is well positioned for the future; however, our future sales volumes will depend on the economic strength of each of our operating markets and our ability to successfully implement our operating strategies in each market.
## Table 2 ##
Sales Order Backlog Sales order backlog represents homes under contract but not yet closed at the end of the period.
Many of the contracts in our sales order backlog are subject to contingencies, including mortgage loan approval and buyers selling their existing homes, which can result in cancellations.
A portion of the contracts in backlog will not result in closings due to cancellations.
The largest percentage increase in our sales order backlog occurred in our East region, reflecting the positive impact of our recent acquisitions of the homebuilding operations of Regent Homes and Crown Communities, which contributed 377 homes to our East region backlog at September 30, 2014.
Crown Communities also contributed 305 homes to our Southeast region backlog at September 30, 2014.
