ANALOG DEVICES, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) expected durations of less than one year.
The Company generally offers a twelve-month warranty for its products.
The Company’s warranty policy provides for replacement of defective products.
Specific accruals are recorded for f known product warranty issues.
Transaction Price: The transaction price reflects the Company’s expectations about the consideration it will be entitled to receive from the customer and may include fixed or variable amounts.
Fixed consideration primarily includes sales to direct customers and sales to distributors in which both the sale to the distributor and the sale to the end customer occur within the same reporting period.
Variable consideration includes sales in which the amount of consideration that the Company will receive is unknown as of the end of a reporting period.
Such consideration primarily includes credits issued to the distributor due to price protection and sales made to distributors under agreements that allow certain rights of return, referred to as stock rotation.
Price protection represents price discounts granted to certain distributors to allow the distributor to earn an appropriate margin on sales negotiated with certain customers and in the event of a price decrease subsequent to the date the product was shipped and billed to the distributor.
Stock rotation allows distributors limited levels of returns in order to reduce the amounts of slow-moving, discontinued or obsolete product from their inventory.
A liability for distributor credits covering variable consideration is made based on the Company's estimate of historical experience rates as well as considering economic conditions and contractual terms.
To date, actual distributor claims activity has been materially consistent with the provisions the Company has made based on its historical estimates.
For the years ended November 2, 2019 and November 3, 2018, sales to distributors were $3.4 billion in both periods, net of variable consideration for which the liability balances as of November 2, 2019 and November 3, 2018 were $227.0 million and $144.9 million, respectively.
Contract Balances: Accounts receivable represents the Company’s unconditional right to receive consideration from its customers.
Payments are typically due within 30 to 45 days of invoicing and do not include a significant financing component.
To date, there have been no material impairment losses on accounts receivable.
There were no material contract assets or contract liabilities recorded on the consolidated balance sheets in any of the periods presented.
The Company generally warrants that products will meet their published specifications and that the Company will repair or replace defective products for twelve-months from the date title passes to the customer.
Specific accruals are recorded for known product warranty issues.
Product warranty expenses during fiscal 2019, fiscal 2018 and fiscal 2017 were not material.

(1) Based on the contractual rate that was being charged at the time the loan was restructured or placed on nonaccrual status.
Cross-Border Outstandings Cross-border outstandings can include loans, receivables, interest-bearing deposits with other banks, other interest-bearing investments and other monetary assets that are denominated in either dollars or other non-local currency.
As of December 31, 2017, 2016 and 2015, there were no aggregate cross-border outstandings from borrowers or counterparties in any country that exceeded 1%, or were between 0.75% and 1% of consolidated total assets.
Derivatives In the normal course of business, we enter into a variety of derivative transactions in order to meet the financing needs of our customers, and to reduce our exposure to fluctuations in interest rates and foreign currency exchange rates.
These transactions include interest rate swap contracts, interest rate options, foreign exchange contracts, residential loan commitment rate locks, forward sale contracts and purchase options.
The assets and liabilities for derivatives on the Consolidated Balance Sheets reflect the market value of these transactions.
We designate certain derivatives as hedging instruments in a qualifying hedge accounting relationship (fair value or cash flow hedge).
Our remaining derivatives consist of economic hedges that do not qualify for hedge accounting and derivatives held for customer accommodation trading, or other purposes.
We monitor the results of each transaction to ensure that management’s intent is satisfied.
We do not use derivatives for speculative purposes.
For additional information regarding our derivative instruments, see Note 13 “Derivatives” in our audited Consolidated Financial Statements in Part II, Item 8 — Financial Statements and Supplementary Data, included in this report.
The table below presents our derivative assets and liabilities.
## Table 2 ##
(1) The notional or contractual amount of interest rate derivatives and foreign exchange contracts is the amount upon which interest and other payments under the contract are based.
For interest rate derivatives, the notional amount is typically not exchanged.
Therefore, notional amounts should not be taken as the measure of credit or market risk as they do not measure the true economic risk of these contracts.
(2) Amounts reflect changes in the treatment of variation margin on certain centrally cleared derivatives.
(3) Amounts represent the impact of enforceable master netting agreements that allow us to net settle positive and negative positions.
At December 31, 2017, the total derivative net asset value decreased $10 million and the total net liability value decreased by $349 million from December 31, 2016 driven by a change in the presentation of variation margin payments in the Consolidated Balance Sheets in 2017.
Effective January 3, 2017, variation margin payments made on certain centrally-cleared derivative contracts were classified as settlement of those derivatives rather than the

Notes to Consolidated Financial Statements Note 3.
Investments – (Continued) The majority of the holdings in this category are collateralized mortgage obligations (“CMOs”) typically collateralized with prime residential mortgages and corporate asset-backed structured securities (“ABS”).
The holdings in these sectors include 515 securities in a gross unrealized loss position aggregating $1,928 million.
The aggregate severity of the unrealized loss was 23.0% of amortized cost.
The contractual cash flows on the asset-backed structured securities are passed through, but may be structured into classes of preference.
The securities in this category are modeled in order to evaluate the risks of default on the performance of the underlying collateral.
Within this analysis multiple factors are analyzed including probable risk of default, loss severity upon a default, payment delinquency, over collateralization and interest coverage triggers, credit support from lower-rated tranches and rating agency actions amongst others.
Securities are modeled against base-case and reasonable stress scenarios of probable default activity, given current market conditions, and then analyzed for potential impact to the Company’s particular holdings.
The structured securities held are generally secured by over collateralization or default protection provided by subordinated tranches.
For the year ended December 31, 2008, there were OTTI losses of $465 million recorded on asset-backed securities.
The remainder of the holdings in this category includes mortgage-backed securities guaranteed by an agency of the U. S.  Government.
There were 272 agency mortgage-backed pass-through securities and 2 agency CMOs in an unrealized loss position aggregating $2 million as of December 31, 2008.
The cumulative unrealized losses on these securities were 2.0% of amortized cost.
These securities do not tend to be influenced by the credit of the issuer but rather the characteristics and projected cash flows of the underlying collateral.
For the year ended December 31, 2008, there were no OTTI losses recorded for mortgage-backed securities guaranteed by an agency of the U. S.  Government.
The asset-backed securities in an unrealized loss position by ratings distribution are as follows:
