Sure. Well, let me start with fourth quarter when we took large impairments and those were primarily related to capital decisions, right? Decisions that we made that were primarily natural gas-related. And this, again, of course, is pre-COVID, but in a capital disciplined way and trying to drive higher returns, being really ruthless about where our capital is invested and making difficult choices. And that was primarily the impact of the impairments that we saw in the fourth quarter. This quarter, it was primarily for two reasons: one, unique situation, Venezuela, which I'll comment on, and I'm sure Jay will add to; and we did lower our price outlook based on the economic impacts from the global pandemic. So we don't know what the impacts will be. But clearly, with the economic contraction and assuming economic recovery clearly, but it just results in lower demand for some time period. And we reflected that in lower prices. So in Venezuela, it's been a difficult operating environment for a while. Each quarter, we've been assessing our investment value. In the second quarter, the environment became even more difficult. As an example, our net production -- our share of net production in June was just 7,000 barrels a day. So it's really fallen off. And so under the accounting rules and the U.S. GAAP accounting rules, we have to assess whether the loss in value is other than temporary. And if we view it as other than temporary, we take an impairment. And unlike IFRS, it's a one -- it only goes in one direction. The other ones were tied to the oil price, and I talked about a few of those, and then we had a severance. So again, we follow U.S. GAAP. We're going to look at it each quarter. What I can say is the impairments this quarter, for the most part, had a different nature than last quarter. And maybe one comment on the price-related ones, and I'll kick it to Jay to talk about Venezuela. The price-related ones are really hitting either mature assets, late-in-life assets, where the remaining production term just gets impacted by the lower price outlook. The long-lived assets all are -- were not impaired. It was really mature remaining short-life direction -- duration where a lower price impacts the carrying value. But maybe Jay can comment on Venezuela.
