Revenue by Product Group The following table shows the percentage of product and related maintenance revenue contributed by each of our five product groups and services during fiscal 2014, 2013 and 2012:
## Table 0 ##
As described in Note 2 in the notes to consolidated financial statements, certain of our licensing arrangements allow customers the ability to remix among software products.
Additionally, we have arrangements with customers that include a combination of our products, with the actual product selection and number of licensed users to be determined at a later date.
For these arrangements, we estimate the allocation of the revenue to product groups based upon the expected usage of our products.
The actual usage of our products by these customers may differ and, if that proves to be the case, the revenue allocation in the table above would differ.
Revenue by Geography
## Table 1 ##
Most of our revenue is transacted in the United States dollar.
However, certain revenue transactions are denominated in foreign currencies, primarily the Japanese yen.
We recognize reduced revenue from those contracts in periods when the Japanese yen weakens in value against the United States dollar and additional revenue from those contracts in periods when the Japanese yen strengthens against the United States dollar.
For an additional description of how changes in foreign exchange rates affect our consolidated financial statements, see the discussion in Item 7A, “Quantitative and Qualitative Disclosures About Market Risk — Foreign Currency Risk.
” Revenue for Asia increased during fiscal 2014, as compared to fiscal 2013 and fiscal 2012, primarily due to increases in revenue from our software business and emulation hardware installations.
For the primary factors contributing to our increase in revenue in other geographies, excluding Japan, see the general description under “Revenue by Year,” above.
Revenue for Japan decreased by approximately $20 million during fiscal 2014, as compared to fiscal 2013, and during fiscal 2013, as compared to fiscal 2012, primarily due to the continued depreciation of the Japanese yen as well as difficult business conditions facing our Japanese customers.
Cadence’s net cash provided by operating activities for fiscal 2018 did not change due to the adoption of Topic 606.
The following table summarizes the effects of adopting Topic 606 on the financial statement line items of Cadence’s consolidated statement of cash flows for fiscal 2018:
## Table 2 ##
Financial Instruments In January 2016, the FASB issued ASU 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.
” Cadence adopted this standard on the first day of fiscal 2018, modifying its accounting and required disclosures for investments in equity securities, other than those accounted for using the equity method of accounting.
Prior to the adoption of the updated standard, Cadence’s investment in marketable equity securities was classified as available-for-sale, and changes in the fair value of the underlying securities were reported in accumulated other comprehensive loss in the consolidated balance sheets.
The new standard eliminated the available-for-sale classification for equity securities and requires changes in the fair value of Cadence’s investment to be recognized through net income for fiscal 2018 and each subsequent reporting period.
Upon adoption, Cadence recorded a cumulative-effect adjustment to increase retained earnings in the amount of $2.6 million related to unrealized holding gains previously recorded in accumulated other comprehensive loss.
Cadence’s non-marketable investments in equity securities consist of investments in privately-held companies and are presented as other assets in the consolidated balance sheets.
Prior to the adoption of the updated standard, non-marketable investments that were not accounted for using the equity method of accounting were recorded at cost, less impairment.
The new standard eliminated the cost method of accounting for investments in equity securities that do not have readily determinable fair values and permits the election of a measurement alternative that allows such securities to be recorded at cost, less impairment, if any, plus or minus changes resulting from observable price changes in market-based transactions for an identical or similar investment of the same issuer.
Cadence adopted the provisions of the new standard applicable to its investments in equity securities without a readily determinable fair value on a prospective basis and elected the measurement alternative for non-marketable investments previously accounted for under the cost method of accounting.
Gains and losses resulting from observable price changes or impairment will be recorded through net income in the period incurred.
For additional information regarding Cadence’s investments in equity securities, see Note 7 to the consolidated financial statements.
Income Tax In October 2016, the FASB issued ASU 2016-16, “Income taxes (Topic 740): Intra-entity Transfers of Assets Other Than Inventory.
” The new guidance requires the recognition of the income tax consequences of an intraentity asset transfer when the transfer occurs rather than when the asset has been sold to a third party.
For intra-
entity transfers of inventory, the income tax effects will continue to be deferred until the inventory has been sold to a third party.
Cadence adopted the new standard on the first day of fiscal 2018 using the modified retrospective transition approach and recorded a cumulative-effect adjustment to decrease retained earnings in the amount of $8.3 million.
The cumulative-effect adjustment includes the write-off of income tax consequences deferred from prior intra-entity transfers involving assets other than inventory and new deferred tax assets for amounts not recognized under U. S.  GAAP.
We anticipate the potential for increased volatility in future effective tax rates from the adoption of this guidance.
Stock-based Compensation In May 2017, the FASB issued ASU 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting,” that provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting.
Cadence adopted the standard on the first day of fiscal 2018.
The adoption of this standard did not impact Cadence’s consolidated financial statements or the related disclosures.
Cumulative Effect Adjustments to Retained Earnings The following table presents the cumulative effect adjustments, net of income tax effects, to beginning retained earnings for new accounting standards adopted by Cadence on the first day of fiscal 2018:
## Table 3 ##
* The cumulative effect adjustment from the adoption of Revenue from Contracts with Customers (Topic 606) is presented net of the related income tax effect of $17.5 million.
New Accounting Standards Not Yet Adopted Leases In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” requiring, among other things, the recognition of lease liabilities and corresponding right-of-use assets on the balance sheet by lessees for all leases with a term longer than 12 months.
The new standard is effective for Cadence in the first quarter of fiscal 2019.
A modified retrospective approach is required, applying the new standard to leases existing as of the date of initial application.
An entity may choose to apply the standard as of either its effective date or the beginning of the earliest comparative period presented in the financial statements.
Cadence adopted the new standard on December 30, 2018, the first day of fiscal 2019, and used the effective date as the date of initial application.
Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods prior to the first quarter of fiscal 2019.
Cadence elected certain practical expedients permitted under the transition guidance within the new standard, which among other things, allowed Cadence to carry forward its prior conclusions about lease identification and classification.
